Reviewing 2015 OLED Industry through Keywords

  1. OLED TV

OLED TV, first released in Q4 2013, recorded approximately 50,000 units of shipment each in Q1 and 2 this year. The shipment increased to 100,000 units in Q3, more than twice the amount of each quarter in H1 2015. As it is estimated that close to 200,000 units were released in Q4, over 90% of LG Displayโ€™s 2015 target is expected to be achieved. This is considered to be showing price competitiveness against other TV as the price of OLED TV fell to 1/2 of the initial price and effectiveness of aggressive marketing emphasizing the advantages of OLED TV compared to newly released LCD TV. In Q3 earnings results announcement, LG Display revealed their plan of 1,000,000 units of OLED TV panel shipment in 2016 and forecast OLED TVโ€™s growth. For the industry, 2015 has been the year that secured foothold for OLED TVโ€™s market expansion.

 

  1. Galaxy S6 Edge

At the time of Galaxy S6 and Galaxy S6 Edgeโ€™s release, Samsung Electronics estimated the initial supply to be 50:50. However, Galaxy S6 Edge showed 70% in actual demand and this led to shortage in supply. Samsung Display met the demand by starting flexible AMOLED line operation earlier than scheduled. 2015 proved future market growth potential by opening consumersโ€™ wallets through designs possible only with flexible AMOLED panel.

 

  1. Samsung Display Supply Diversification

During the Q3 earnings announcement, Samsung Display revealed their plan to expand non-Samsung clients by 30%. Accordingly, in Q3, when smartphone marketโ€™s growth was expected to slow down, the sales performance improved by 13% compared to its previous quarter through key clientโ€™s new product release and expansion of client base. Particularly, the market occupation of AMOLED panel shipped toward China is analyzed to have increased within the global mobile market as Chinese set companies released AMOLED panel equipped smartphones.

 

  1. Appleโ€™s OLED Application

Apple, which has been using LCD panel for all products, first applied flexible AMOLED panel, produced by LG Display, to 2015 smartwatch Apple Watch and drew much attention. In H2, Apple diversified suppliers by using Samsung Displayโ€™s flexible AMOLED panel. This move is analyzed to be groundwork for flexible OLED application to smartphone following smartwatch. 2015 has been a year with much interest in when flexible AMOLED panel equipped iPhone will be released.

 

  1. OLED Lighting

Global OLED lighting industry went through a great transformation in 2015. OLEDWorks announced they will acquire key parts of Philipsโ€™ OLED lighting business, relevant production facilities, and intellectual property. With this take over, OLEDWorks greatly expanded business through widened product portfolio and simultaneous lighting panel mass production in the US and Germany. LG Chem. transferred OLED lighting business to LG Display. The value of transfer is 1.6 billion KRW, and it is seen to be a strategy to increase competiveness by transferring the business to LG Display with their OLED panel mass production knowledge and to focus on existing materials business. The take over and business transfer of the main players in OLED lighting industry, OLEDWorks and LG Chem., are following their own business strategy. However, following these moves, related investment is expected to be delayed for some time and eyes are on how these will affect the OLED lighting business overall.

Koreaโ€™s Last PMOLED Company to Fade into History?

NeoView Kolon, a subsidiary merged by Kolon Group in order to foster electronics business in 2001, is known within the industry to close down the PMOLED sector on December 31.

 

NeoView Kolon established factory in Hongseong, South Chungcheong Province of South Korea in 2003 and began PMOLED mass production. At this point, Samsung SMD (the current Samsung Display) and LG Electronics were also mass producing PMOLED. Other PMOLED producing companies included Koreaโ€™s Orion, Japanโ€™s Futaba, and Tohoku Pioneer, and Chinaโ€™s Visionox. However, Samsung SMD stopped PMOLED business and sold manufacturing equipment to Chinaโ€™s Truly, and Samsung Display began AMOLED business from 2007. Subsequently, LG Electronics also closed down PMOLED sector and merged OLED related personnel to LG Display and launched AMOLED business. Orion was sold to Chinaโ€™s Changhong.

 

With the active application of AMOLED to Samsung Electronicsโ€™ Galaxy series, global PMOLED business began to rapidly shrink, and in order to maintain business, PMOLED companies pushed ahead with OLED lighting panel business.

 

NeoView Kolon entered into the automotive instrument panel business with PMOLED transparent display, but this business was also not easy. Furthermore, as the factory location is Hongseong, deep in the countryside, there was high turnover of employees and difficulty in technology development and recruitment. Despite the investment of over 100,000 million KRW, the company showed continued deficit.

 

NeoView Kolon turned into a financial sinkhole for Kolon Group and worsened the Groupโ€™s financial structure, leading to persistent discussion of selling or withdrawal of the business. Recently, Samsung Display is actively pushing forward the transparent AMOLED panel business. As such, transparent display business value for Kolon decreased, and it is estimated that this led to the decision of closing down the business.

New Products to be Released Using Visionoxโ€™s AMOLED Display

On Dec. 25th, Visionox announced that two products using its display panels will soon be released, including a 5.5 inch AMOLED display applied to high-end smartphone, and a 1.45 inch AMOLED display applied to smartwatch.

NTHU is reshaping the lighting world via Candlelight OLED

Numerous researches have been sounding alarm with increasing frequency on the health hazards of blue light. They report that blue light possesses potential hazard to the retina of human eyes, circadian rhythm, melatonin secretion, and cancer risk.

 

To devise a human-friendly light source and to also trigger a โ€œLighting Renaissanceโ€, the Prof. Jouโ€™s OLED research group from National Tsing Hua University (NTHU), Taiwan, demonstrates a high light quality and blue-hazard free candlelight OLED, that serves as a good measure and a wisely choice for general lighting. Just before Christmas, the candlelight OLED has won the International Dark-Sky Association Lighting Design Award and Domestic golden lighting medal. Moreover, Taiwan’s government highlights and entirely promotes NTHU and WiseChip Semiconductor Inc. to further investigate candlelight OLED technology via the highest Ministry of Economic Affairs support in following two years. Itโ€™s surely confirmed that the health-friendly candlelight OLED can be commercialized, accessible and affordable for human mankind by the end of 2017.

 

Additionally, the IDA website announced that โ€œSince 2006, Prof. Jou has worked with students on organic LED (OLED) lighting technologies in an effort to create lighting that minimizes negative impacts to human health. In this work, he and his research team has made numerous breakthroughs, such as the creation of very low color temperature OLED, sunlight-style OLED, pseudo-natural light OLED, and candlelight-style OLED devices. Their candlelight-style OLED has attracted a considerable attention from both academia and industries. Most importantly, the candle-like OLED has also been praised by medical experts and is considered one of the safest electricity-driven lighting sources. This lighting can be used in both indoor and outdoor applications.โ€

 

Upcoming lighting industrial trends should be psychological- and physiological- friendly lighting sources. Currently, the gross production value of OLED up to 4,000 billion US dollars.

Transparent Electrode Needs Development for Next Generation Display to Surge

Recently, with various research results regarding transparent electrode, interest in next generation transparent electrode is increasing.

 

In early December, UNIST (Ulsan National Institute of Science and Technology) developed printing technology that can arrange the Ag nanowire in the direction chosen on top of substrate. Ag nanowire is transparent electrode that can be applied to large area flexible touch panel and display products. This technology allows the surface to be flat through the fusion of nanotechnology to the existing printing process and increases transmittance.

 

Around the same time, ETRI (Electronics and Telecommunications Research Institute) developed technology that replaces thin metal electrode on top of OLED substrate with graphene transparent electrode. The metal electrode that were being used in OLED was mostly silver (Ag) material, but due to the reflection of internal light, the viewing angle changed depending on the angle. The external light also affected picture quality due to reflection. The newly developed technology used graphene that mostly does not reflect internal/external light as transparent electrode and improved transmittance and picture quality.

 

At present, ITO (indium tin oxide) is most widely used as transparent electrode materials. However, the supply is limited and flexible electronic device application is narrow. As such, the demand for the development of new materials that can replace this is greatly increasing. Particularly, as ITO is not suitable for stretchable device, the next generation transparent electrode development is considered to be a key issue for future display.

 

At 2016 Production/Process Technology Development and Application Cases by Flexible Transparent Electrode and Film Materials Seminar (December 17) held in Seoul, South Korea, Dr. Won Mok Kim of KIST (Korea Institute of Science and Technology) discussed, of many flexible transparent electrodes, TCO (transparent conductive oxide) production and process technology through presentation titled โ€˜TCO based flexible transparent electrode production and process technology development trend and applicationsโ€™.

 

Of the transparent conductive materials, oxides have been researched the longest, and they are most widely used transparent conductive materials. Oxide including conductive materials have optical band gap of โ‰ฅ3.0 eV and therefore has high transmittance and can be flexible. Kim revealed that TCO needs further improvement in conductivity and transmittance for display application.

 

Regarding transparent body, when refractive indexes of components are different, the path of light through the transparent body is refracted. When this occurs, the object becomes hazy although transparent. Haze is quantified and used to assess the transparent bodyโ€™s performance. Kim explained that for solar cell the haze is purposefully increased to transmit more light to the internal active materials. However, if the display is clouded the clarity of image is reduced and therefore haze has to be lowered. To achieve this, Kim reported that the TCOโ€™s surface roughness has to be reduced.

 

Kim revealed that there are two issues, temperature and flexibility, when TCO is used as transparent electrode. ITOโ€™s conductivity is highest at 300 โ„ƒ, and for ZnO it is around 200 โ„ƒ. Channel cracks could occur with TCO when higher than bending strain is applied, and the crack could snap when it is bent further, destroying the device performance. Kim explained that to increase the bending strain, the thickness has to be reduced. However, when doing so as the sheet tension increases, the process has to be designed carefully considering the tradeoff.

 

Transparent electrode could be applied to display, solar cell, touch panel, and lighting among others and therefore requires much development. Although oxides have been long researched as transparent electrode materials, Kim concluded that even more diverse value can be created through fusion with next generation materials.

OLED and Graphene Together Achieves Innovative Technology

By Choong Hoon Yi

 

Korean research team is expected to greatly improve displayโ€™s transmittance and picture quality through fusing graphene technology, focus of much attention as the new material to OLED technology.

 

On December 15, ETRI (Electronics and Telecommunications Research Institute) replaced the thin metal electrode that was used as transparent electrode on top of the OLED substrate with graphene transparent electrode, and succeeded in developing original technology that is conductive and transparent.

 

This research results were presented in Scientific Reports, a journal from the publishers of Nature on December 2.

 

The metal electrode used in OLED until now has been mostly silver material, but due to the reflection of internal light, the viewing angle changed depending on the angle. The external light also affected picture quality due to reflection.

 

In order to solve this problem, ETRI research team focused on graphene that mostly does not reflect internal/external light. By replacing the material, the team reported that the transmittance increased by approximately 40% and reflectance improved by approximately 60%.

 

OLED was successfully lighted by attaching graphene transparent electrode to the organic layer on top of the film form (23 x 23 mm, 30 ใŽ› thickness) of substrate. The research team believes this will be able to contribute much when applied to transparent OLED display and white OLED-based large area OLED display in future.

 

Particularly, unlike the existing vacuum process OLED production method, this technology can be employed via lamination where film is attached to the organic layer and graphene. Therefore, OLED can be produced through simpler process. It is expected that this can be evolved into production technology using roll to roll process.

 

Additionally, ETRI, together with Hanwha Techwin, is working on applying graphene transparent electrode to OLEDโ€™s lower electrode through collaboration of high quality graphene thin film electrode materials. The related technology development results were published online by The IEEE (Institute of Electrical and Electronics Engineers) of Selected Topics in Quantum Electronics.

 

ETRIโ€™s Dr. Jeong-Ik Lee (soft I/O interface research section) anticipated that โ€œthis technology will be able to play a role in widening the gap with latecomer countries in OLED industry where challenging latecomers are strongโ€.

 

This research was carried out through Koreaโ€™s Ministry of Science, ICT and Future Planning and Institute for Information & Communications Technology Promotion (IITP)โ€™s โ€œEnergy reducing environment adapting I/O platform technology development for future advertisement serviceโ€ project and Ministry of Trade, Industry and Energy and Korea Evaluation Institute of Industrial Technologyโ€™s โ€œSubstrate size 5.5 generation or larger graphene film and OLED device/panel foundation and application technology development for graphene materials OLED transparent electrode and thin film encapsulation applicationโ€.

 

ETRI is planning to additionally develop sheet tension reducing technology by manufacturing metal in thin, grid forms and enlargement technology to produce mobile display size within 2016.

 

Through this technology, the research team produced 6 international patent applications and 6 papers. ETRI is intending to transfer the technology to graphene film and display panel companies among others. Commercialization is estimated to begin after 3 years.

[Process Explanation]

After manufacturing laminated film, formed with bonding layer (BL) and PET film, using surface treated substrate, graphene transparent electrode is transferred on to the bonding layer. By laminating the laminated film that includes graphene transparent electrode on the substrate (lower electrode and organic layer), OLED where graphene transparent electrode is used as upper electrode is complete.

Heraeus Materials Reveals Innovative Conductive Polymer Transparent Electrode

Heraeus Materials Koreaโ€™s Jinwhan Kim

By Choong Hoon Yi

 

At 2016 Production/Process Technology Development and Application Cases by Flexible Transparent Electrode and Film Materials Seminar (December 17), Heraeus Materials Koreaโ€™s Jinwhan Kim revealed new product of Clevios, Heraeusโ€™ main transparent electrode series, through a presentation titled Conductive Polymer-based Flexible Transparent Electrode Production and Process Technology Development Trend and Application Examples.

 

Transparent electrode possesses high transmittance of โ‰ฅ 80% and conductivity of โ‰ค 500 ฮฉ/ใ…, and is being used as electronic component for displays including OLED electrode. The transparent electrode can be mainly categorized into 3 types: thin metal film, carbon allotrope, and conductive polymer. Heraeus Materials is considered a major company producing conductive polymer together with SKC.

 

Although many people regard Heraeus as a company producing gold and silver bullion, Kim explained that Heraeus is focusing on display and semiconductor related chemicals. Particularly, Kim added that Clevios, Heraeusโ€™ representative product, contains over 20 years of PEDOT materials know-how and experience.

 

Clevios™ P, the existing PEDOT:PSS product, is mostly produced in Leverkusen, Germany, and essentially uses thermal curing. Kim revealed that when Clevios™ P is coated, it shows bluish hue and the degree changes depending on the thickness. The conductivity is 1,000 S/cm and has the refractive index similar to glass.

 

While the existing Clevios product has sufficient flexibility to be applied to flexible products, Kim reported that future flexible display requires transparent electrode with higher specifications, emphasizing the importance of product development, and introduced new product Clevios™ HY.

 

High conductive transparent electrode, Ag nanowire was added to the existing Clevios PEDOT:PSS product to produce Clevios™ HY. AG nanowire typically has rough surface but Clevios PEDOT:PSS corrects this by making it flat. The highly flexible new product has relatively low sheet tension of less than 100 ฮฉ/ใ…. Kim emphasized that this new product can be turned to solvent base and used in printing process, revealing they are developing Clevios™ HYJET, a PEDOT:PSS transparent electrode for printing use.

Now is the Time to Invest for OLED to be the Next Generation Display

By Hyun Jun Jang

 

 

 

 

On December 10, a seminar specializing company bizocean held โ€˜2016 Next Generation Displayโ€™s Latest Trend and Cutting Edge Industry Application Issues and Business Creation Seminarโ€™ in Korea Technology Center. Professor Changhee Lee of Seoul National University, the first speaker of the seminar, announced that as OLED will become the technology for future display, now is the time for investment by the companies.

 

Lee reported that the display follows cameraโ€™s resolution, and although resolution has been developed up to UHD, he forecast that it will advance further. He also added that higher the resolution, the display performance that consumers demand will increase.

 

Regarding the current display market status, Lee explained that as the LCDโ€™s margin is falling the market has to turn to OLED, but it is still expensive and capacity is low. Additionally, from the way consumers are still using the term liquid crystal regarding Samsungโ€™s AMOLED smartphone, Lee speculated that people have difficulty in distinguishing between LCD and OLED. He told the audience that the industry should inform the public of the OLEDโ€™s differences from LCD through transparent, flexible displays that show OLEDโ€™s superior traits, and open the market through product differentiation strategy.

 

For the future display, Lee pointed out printing OLED. He explained that although printing OLEDโ€™s lifetime, particularly blueโ€™s, falls short compared to vacuum evaporation, it is estimated to reach commercialization stage after 2-3 years. Despite the flaws in terms of materials, Lee reported that the advantages such as reduced production cost, fast tact time, and material usage efficiency will lead to the opening of the market. For these reasons, Samsung and LG are carrying out development.

 

Lee forecast that LCD, in its maturity stage of the industry life cycle, will lead the market for a while, but OLED technology will rapidly evolve and become the focus of the next generation display market. Regarding OLED TV, Lee mentioned that large area OLED mass production through printing technology is urgent in order to achieve price competitiveness. At present, OLEDโ€™s capacity is less than 1/100 of LCD. As such, even if there is demand, supply may not be able to meet it and Lee suggested the need for investment to the companies. He added that if there is low supply when the number of customers is high, the opening of the market could be delayed.

Lee mentioned QLED as another future display technology. QLED has the same structure as OLED but uses quantum dot as the emitting materials, changing colors through different sizes. Lee reported that the color gamut is high as the wavelengths are shorter than OLED emitting materials. Also as the same material is used, QLED has an advantage of reduced material production cost and development of micro display with 2,000 ppi is complete. However, Lee added that as the lifetime is nowhere near sufficient, commercialization stage is still far away.

[Analyst Column] LCD Industry Administration to Worsen after 3 Years

Choong Hoon Yi, Chief Analyst, UBI Research

 

 

BOE is intending to carry out a large amount of investment in order to operate Gen10.5 LCD line from 2018. Meanwhile, key set makers including Apple, Samsung Electronics, LG Electronics, and Panasonic are devising strategy to move from LCD to OLED for smartphone and premium TV displays. As such, it is becoming more likely for the LCD industry to be in slump from 2018.

 

At present, the area where LCD industry can create profit is LTPS-LCD for smartphone. The forecast smartphone market for this year is approximately 15 billion units. Of this, Samsung Electronics and Apple are occupying 20% and 15% of the market respectively. OLED equipped units are less than 2 billion.

 

However, from 2018 the conditions change greatly. Firstly, Apple, which has been using LCD panel only, is estimated to change approximately 40% of the display to OLED from 2017 earliest and 2018 latest. Apple is testing flexible OLED panels of JDI, LG Display, and Samsung Display, and recommending them to invest so flexible OLED can be applied to iPhone from 2017. The total capa. Is 60K at Gen6. As new investments for Gen6 line of Samsung Display and LG Display are expected to be carried out from 2016, supply is theoretically possible from 2017.

If 5inch flexible OLED is produced from Gen6 line, under the assumption of 50% yield at 60K capa. 65 million units can be produced annually, and approximately 1 billion units if the yield is 80%. If Appleโ€™s iPhone shipment in 2017 is estimated to be around 2.7 billion units, within the 50-60% yield range approximately 25% of the display is changed to OLED from LCD, and if yield reaches 80% around 40% will change. The companies that are supplying Apple with LCD for smartphone, LG Display, JDI, and Sharp, are expected to show considerable fall in sales and business. These 3 companies could be reduced to deficit financial structure just from Appleโ€™s display change

 

Furthermore, as Apple is not producing low-priced phones, under the assumption that future iPhone could all have OLED display, Apple could cause the mobile device LCD industry to stumble after 3 years.

 

Samsung Electronics also is gradually changing Galaxy series display to OLED from LCD. Of the forecast 2015 shipment of 3 billion units, 50%, 1.5 billion units, has OLED display, but Samsung Electronics is expected to increase flexible OLED and rigid OLED equipped products in future. Particularly, as Apple is pushing for flexible OLED application from 2017, Samsung Electronics, whose utilizing OLED as the main force, is estimated to increase flexible OLED usage more than Apple. It is estimated that all Galaxy series product displays will be changed to OLED from 2019.

 

 

Under these assumptions, of the estimated smartphone market in 2020 of approximately 20 billion units, Samsung Electronics and Appleโ€™s forecast marketsโ€™ 7 billion could be considered to use OLED.

 

Samsung Display is strengthening supply chain of set companies using their OLED panels. Samsung Display is supplying OLED panels to diverse companies such as Motorola and Huawei as well as Samsung Electronics, and also expected to supply rapidly rising Xiaomi from 2016. If smartphone display is swiftly changed to OLED from LCD from 2017, Chinese display companies that are currently expanding TFT-LCD lines are to be adversely affected.

 

Additionally, in the premium TV market, LG Electronics mentioned that they will focus on OLED TV industry at this yearโ€™s IFA2015. As a part of this, LG Display is planning to expand the current Gen8 34K to 60K by the end of next year. Furthermore, in order to respond to the 65inch market, Gen9.5 line investment is in consideration. In the early 2015, Panasonic commented that they were to withdraw from TV business but changed strategy with new plans of placing OLED TV on the market in Japan and Europe from next year.

 

As Samsung can no longer be disconnected from the OLED TV business, there are reports of investment for Gen8 OLED for TV line in 2016. Although OLED TV market is estimated to be approximately 350 thousand units this year, in 2016, when Panasonic joins in, it is expected to expand to 1.2 million units. The OLED TVโ€™s market share in โ‰ฅ55inch TV market is estimated to be only 4% but in premium TV market it is estimated to be significant value of โ‰ฅ10%.

 

 

 

 

If Samsung Display invests in Gen8 OLED for TV line in 2016, from H2 2017 supply to Samsung Electronics is possible. As OLED Gen8 lineโ€™s minimum investment has to be over 60K to break even, it can be estimated that Samsung Display will invest at least 60K continuously in future.

 

Under these conditions, LCD industry can only be in crisis. Firstly, it becomes difficult for Sharp to last. Sharp, which is supplying TFT-LCD for Appleโ€™s iPhones and LCD for Samsung Electronicsโ€™ TV, will lose key customers. Secondly, BOE, AUO, and JDI, the companies selling LCD panels to these companies, are not ready to produce OLED and therefore damage is inevitable.

 

BOE is carrying out aggressive investment with plans to lead the display industry in future with operation of Gen10.5 LCD line. Therefore, from 2018, as the main cash cow items disappear, administration pressure could increase.

[2015 OLED Evaluation Seminar] Oxide TFT Technology that 2015 should Spotlight

By Hyun Jun Jang

 

During the 2015 OLED Evaluation Seminar (December 4) hosted by UBI Research, Professor Jin-Seong Park of Hanyang University gave a presentation titled OLED Oxide TFT Technology Trend, discussing oxide TFT, related industry, and technological issues as well as TFT technology that should receive the spotlight in 2016.

 

Oxide TFT has an advantage of high mobility and large area uniformity compared to a-Si TFT. As such, it is being more applied to large area OLED panel and used in LG Displayโ€™s OLED TV.

 

Park revealed that there are mainly 4 issues regarding oxide TFT and led with the reliability issue. Oxide TFT is essentially in amorphous state but when crystalized, the density and crystallizability increase; as oxygen does not move away and stay in place, defects occur less and reliability is high. Japanโ€™s SEL and Sharp published CAAC (C-Axis Aligned Crystal) structure related oxide TFT paper, and Cornell University produced CAAC oxide TFT by increasing the substrate temperature and adjusting oxygenโ€™s partial pressure.

 

The second issue is composition ratio. Park reported that composition ratio is the most closely related characteristic to TFTโ€™s mobility. He revealed that recently research is being carried out centering around IGZO (indium gallium zinc oxide), but also oxide TFT research with different composition ratio is continually published. For example, ITZO (indium tin zinc oxide)โ€™s mobility has been reported to reach 30cm/Vsec, and BOE is working on the related research. Research results, which showed increased mobility and reliability for IGZTO, which is IZTO with G added, was published, as well as ZnON (zinc oxide nitride) TFTโ€™s 100cm/Vsec mobility. BOE demonstrated ZnO TFT applied 14.1inch AMOLED.

 

The third issue is the device structure. Park explained that efficiency can increase when top gate structure is used to oxide TFT as parasitic capacitor is not needed, but that the process is difficult. However, Park reported that JOLED revealed when self-alignment is used the number of masks used can be reduced and increases performance. This structure is applied to OLED TV by LG Display.

 

Lastly, Park gave the safety of device as the last issue. Oxide TFT can exhibit degradation effects from light, oxygen, hydrogen, and moisture. Park reported that hydrogen particularly has great effect on the safety. He explained that although the current prevailing OLED TFT is LTPS, as the panel becomes larger there will be technological competition between oxide and LTPS. Reporting that TFT which is cost efficient and shows high performance in diverse factors such as resolution will dominate the market, Park concluded his presentation.

 

 

 

[2015 OLED Evaluation Seminar] Professor Hong Mun-Pyo of Korea University Retraces Flexible OLEDโ€™s Key Issues

By Hyun Jun Jang

 

During the 2015 OLED Evaluation Seminar (December 4) hosted by UBI Research, Professor Hong Mun-Pyo of Korea University gave a talk titled Flexible AMOLED Gas Barrier Technology Development Status. Through this presentation, he discussed in detail flexible OLEDโ€™s outline, technological issues, and encapsulation among other key issues.

 

Flexible display signifies a display that was produced on top of flexible substrate, and not an existing glass substrate, which can bend, fold, or roll without breaking. Hong emphasized flexible display is the next generation display that can simultaneously satisfy consumers and panel makers, and an area that OLED can be more valuable compared to LCD.

 

There are 3 essential issues in flexible display, substrate, TFT array, and display processes, as well as ancillary issues such as application and cost. Hong reported key issues regarding substrate and display process.

 

Flexible display uses plastic substrate, instead of glass, that is strong against shock and can bend. Therefore, handling technology that manages plastic substrate is considered a key technology in flexible display production. Hong revealed that for handling technology, a film lamination method and vanish coating method are mainly used. A film lamination method is where plastic substrate is attached to carrier glass using adhesive before being processed and a vanish coating method is where the PI substrate is coated to the carrier glass before processing. He emphasized that no matter which method is used, the debonding technology used to detach the plastic substrate from the glass plays a crucial role in deciding yield.

 

Hong followed the substrate discussion with encapsulation technology. Encapsulation technology prevents moisture and oxygen that affect OLED panelโ€™s performance from infiltrating in order to increase the displayโ€™s lifetime. As it is a core process that decides OLED panelโ€™s yield, OLED panel production companies are focusing on optimum encapsulation technology development.

 

Key issues of encapsulation technology that is currently being applied to flexible OLED, barrier coating related issues are considered the most important. Barrier coating is the coating applied to the plastic substrate to overcome the limitations that occur as existing glass substrate is replaced by plastic. For flexible encapsulation, as can type or frit seal technologies that were used for glass encapsulation cannot be used, face seal or TFE technologies that can be applied to flexible are used. Also, as the permeability of oxygen and moisture has to be 10-6g/m2day or less, high performing barrier coating technology is needed.

 

When barrier coating is used to flexible OLED, generally 3 problems occur. Firstly, physically cracks or particles can develop. Regarding this, Hong explained that this issue can be solved if process is properly maintained. The second problem is micro defects that can arise on the surface of plastic film, which can be solved through optimized process, according to Hong. Lastly, nano-sized pin holes can come up. Hong revealed that multi-layers of barrier coating can solve this problem.

 

Generally, when OLED panel is produced the thickness of encapsulation layer is not a big issue. However, Hong emphasized that the thickness becomes a core issue when producing flexible OLED panel. He reported that hybrid structure of encapsulation where gas barrier cover plate is attached to passivation layer placed via PECVD can be the solution.

 

Although the most suitable process technology for hybrid encapsulation production is R2R, as appropriate results are not obtained when CVD is applied to R2R, Hong reported that research is being carried out toward the sputtering using direction. He revealed that if reflection plate is added to the sputtering equipment and neutron beam release is induced, defects that occur during the sputtering process can be reduced as the target thin film stabilizes.

[2015 OLED Evaluation Seminar] Can LG Display and Samsung Display Become OLED Marketโ€™s Rule Maker?

By Hyun Jun Jang

 

At 2015 OLED Evaluation Seminar (December 4) hosted by UBI Research, UBI Researchโ€™s president Choong Hoon Yi gave a talk titled AMOLED Panel Industry Trend and Market Forecast discussing OLED industry until 2015 and forecasting 2016 OLED market.

 

Yi presented 2 issues related to flexible OLED. The first issues he discussed was regarding foldable types in foldable display. Yi explained that in-folding is where display is placed inside and out-folding has display on the outside, and revealed that in-folding type is mainly being developed. He also added that these technologies will be useful in FinTech (financial technology: new form of financial technology using mobile, social network, big data, etc.).

 

According to Yi, another issue for flexible display is film application. In order to increase the yield of flexible display, film has to replace cover glass. However, this could lead to unpleasant touch sensation and Yi emphasized technology such as polishing has to be applied to improve this to convince the consumers.

 

Regarding the market, Yi estimated that the total global smartphone market will grow to record approximately 2,000 million units until 2020, with Samsung Electronicsโ€™ 400 million units. He also estimated that the OLED display proportion of Samsungโ€™s Galaxy series will continue to increase and that most of Galaxy products will have AMOLED panel in 2019. Of this, Yi announced that flexible OLED and rigid OLED are to record approximately 280 million units and 120 million units respectively. He also forecast that the OLED TV market will grow into approximately 11 million units and that materials and equipment companies will rapidly grow.

 

At present, the display market is entering low growth state, and companies are focusing on strengthening the market competitiveness through new technology development and production potential increase. Samsung Display is actively striving to increase OLED panelโ€™s supply for external companies. LG Display announced 1.84 billion KRW investment for worldโ€™s largest OLED focused P10 factory and other areas.

 

Yi reported that as flexible OLED evolves, the mobile display resolution competition of the present will disappear, and he estimated that as LTPS-LCD market decreases, the sales of related panel companies, such as BOE, Sharp, JDI, and LGD, will diminish.

 

Yi also told the audience that he is expecting Samsung Electronics to put OLED TV on the market from 2018 and the sales of the companies, Sharp, AUO, and CSOT, that were supplying them with LCD panels will fall. Essentially, he explained that as the OLED market grows, LCD dealing companiesโ€™ position will weaken which will lead to the strengthening of OLED panel production and related companiesโ€™ position.

 

When asked about the future of Korean display panel companies, Yi replied that when LCD and OLED are competing, set companies decides the market. However, if OLED can unite the market, Yi emphasized that the display panel will be rebranded as Rule Maker and LG Display and Samsung Display will be in its center.

[Expert Talk] Interview with SAES Group’s Dr. Mauro Riva

Dr. Mauro Riva, SAES Groupโ€™s OLED/OLET business developer, kindly answered a few questions regarding OLED for OLEDNET. He will be speaking at the 2nd OLED KOREA Conference (February 24-25, 2016) in Seoul, Korea.

 

With much thanks to Dr. Riva for taking the time to answer some questions, here is the full script of the interview.

 

  • What is your personal opinion on OLEDโ€™s marketability?

I believe that OLEDs have just to leverage on their unique, distinctive properties, in order to enable brand new market segments, rather than entering competition in already crowded and established markets. I mean that the specificities of organic materials make them the only candidates for creating an entire future portfolio of portable, flexible, feather-light and, possibly, low power high definition display devices.

Thus, the ability to generate really new, fancy, conformable and sustainable displays is, in my opinion, the first ingredient to boost OLEDโ€™s marketability. The second ingredient could be, in the long run, lower raw material and manufacturing costs, with respect to competing display technologies.

 

  • Is there a particular reason for your choice to speak at the OLED specific conference rather than a more general IT conference?

As an advanced materials Company, SAES Group have developed a comprehensive portfolio of functionalized polymer composites, to be integrated in a plurality of OLED device architectures. For this reason, an OLED specific conference is the perfect place to directly discuss the important theme of encapsulation, with the people working everyday on this peculiar technology. We wanted to have a direct and frank debate with scientists and technicians specifically involved in OLEDs, rather than in general IT themes, in order to be far more focused on the manifold organic diode encapsulation issues.

 

  • What are the latest issues on OLED encapsulation?

I think that OLEDs are nowadays facing the same issues they had since the beginning: basically, OLED materials are extremely sensitive to oxidizing agents and, especially, to moisture. This requires encapsulation materials with exceptionally high barrier properties, and active fillers or getters, capable of absorbing water on a single molecule basis. The optimization of many functional properties in single encapsulating materials is a very complex materials science problem. The fact that OLED materials can also be very sensitive to heat or radiations, generates many process constraints as well.

It turns out that encapsulation materials must be specifically engineered taking into account the OLED structure, the device architecture, the chemical and physical nature of the materials and, nevertheless, the specific processes to be applied. Perfecting OLED encapsulation is thus a very challenging task, which requires deep technical interaction between advanced encapsulation materials providers and OLED makers.

 

  • Could you tell me about development concept and characteristics? Also perhaps recent performances and outcome?

As far as the Organic Electronics Business Development Area is concerned, we provide a very large portfolio of active edge sealants, active transparent fillers, dispensable getters. These products come as the result of our deep know-how in functional polymer composites, and they are specially tailored to address customersโ€™ specific OLED designs and processes. Leveraging on our functional polymer composite technology, we have been able to develop solventless formulations, with water sorption capacities exceeding 13 percent in weight and very high flexibility and adhesiveness for fully bendable devices. Our products can be applied via screen printing, blading, syringe, ink-jetting, ODF and even be employed in thin film encapsulation structures, to make them simpler and more reliable.

Together with the functional polymer composite based products, we also provide high performance tape dryers, as thin as 110 microns, for R&D and small scale bottom emission OLEDs. Another important class of products is related to AlkaMax: this technology offers an efficient and safe method of depositing ultrapure alkali metals. Our alkali metal dispensers and pills keep the alkali metal pure in the form of a stable salt, until it is thermally activated in the evaporation chamber.

 

  • What are OLED related main manufacturing equipment type and who are your main clients?

We see syringe dispensing as one of the main methods for dispensing our functional polymer composites. Ink-jetting is also becoming more and more widespread, together with ODF, especially for active fillers. As of today, we get the most revenues in this field from PMOLED makers. The AMOLED market is broadening, and we have some very good customers there as well, who are especially in need of effective solutions for smartphone and tablet size high definition displays. OLED lighting is still early stage, but we are already collaborating with the major players in that field, so far at R&D or pre-production stage. The main market for our products for the organic electronics market is indeed Asia.

 

  • Are there any areas where you are collaborating with material companies?

We have many collaborations worldwide, with other material companies as well. Regarding the functional polymer composite technology, we are collaborating in the areas of organic electronics, specialized food packaging and gas barrier films.

We are also engaged in very fruitful collaborations with specialized equipment makers.

ย 

  • Is there anything you would like to add?

I would just kindly invite everyone who is interested in OLED encapsulation to visit our website and to directly contact us, for deepening all the technical aspects about our product portfolio.

The proactive and collaborating approach with our customers and the Research and Innovation focus have always been the heart of our Company way of doing: the OLEDs world offers us a real exciting and challenging arena for making innovation happen, together with all the players involved in this fascinating emerging technology.

Planar Aims for Transparent OLED Product Mass Production in Feb 2016

On November 30 (local time), a US based display production company Planar held an online presentation titled โ€˜Planar Look Thru OLED Transparent Display Webinarโ€™, discussing transparent display traits and disclosing specifications for products which are estimated to be mass produced from February 2016.

 

Transparent display is defined as a display with see-through screen showing objects behind the display as well as the display contents. Recently, it is receiving much attention as a technology with high potential for diverse applications expanding existing display industry.

 

Planar explained that unlike the existing display, transparent display pixels are separated into transparent and emitting areas with RGB subpixels located in the emitting area. Planar clarified that what is black on general display becomes see-through and white becomes opaque.

 

Transparent displayโ€™s performance is decided by several factors such as transmittance, brightness, and color gamut. Regarding this, Planar revealed that the transmittance of transparent display is not fixed but can be affected by ambient light; brighter the surrounding environment, higher the transmittance. Additionally, viewers have tendency to perceive the display with higher color gamut as brighter than the actual brightness, and transparent displayโ€™s color gamut is therefore an important factor.

 

In early 2015, Planar revealed a 55inch transparent OLED display prototype. At present, Planar is receiving pre-order and aiming for mass production in February 2016. The company also reported basic specifications for the panel: 45% of transmittance, 100% color gamut, and Full HD (1,920×1,080) of resolution. The product also has 5 input sources: 4 HDMI terminals, and 1 display port.

 

During the webinar, Planar explained that 32 touch points using IR (infra-red) touch system installation is an option. Although this is less accurate than touch system using touch film, Planar explained that this was an unavoidable choice in order to increase the transmittance. They also added that they are continuing research for new touch system application.

 

The 55inch panel price starts from under USD 15,000 and Planar is currently receiving pre-order. Although there are many factors that affect transparent OLEDโ€™s lifetime, it was measured to be 20,000 hours at LT50. Answering the question on whether it is affected by UV light, Planar explained that it can be UV sensitive and the product was designed to be an indoor installation.

 

It is estimated that the transparent OLED panel used in the Planarโ€™s product released is produced by Samsung Display as it has the same 45% transmittance, 1920×1080 resolution, and 400nit brightness.

Professor Jang-Ung Park of UNIST Discusses Transparent Electrodeโ€™s Present and Future

During the International Advanced Materials & Application Technology Expo (November 25-27), Professor Jang-Ung Park of Ulsan National Institute of Science and Technology (UNIST) gave an in-depth lecture on transparent electrodeโ€™s new technology and research results under the presentation title of โ€˜Technology Trend and Development Direction of High Performance Transparent & Stretchable Electrodes Using Graphene and Ag Nanowire Complexโ€™.

 

Transparent electrode is an electronic component with usually โ‰ฅ80% transparency, and sheet tension of โ‰ค500ฮฉ/ใ… of conductivity. This technology is widely used in electronics including LCD front electrode and OLED electrode in display, touchscreen, solar cell, and optoelectronic device.

 

Park explained that the main market for transparent electrode is display and touchscreen, and announced that the transparent electrode market is to grow into US$4,800 million in 2020 from 2015โ€™s US$ 3,400 million.

 

The electrode materials that is mainly being used at present is ITO (indium tin oxide) film produced through evaporation or sputtering. ITOโ€™s merits include good conductivity from the low sheet tension and suitable for mass production. However, China is the main producer of the rare main material, indium, and has a drawback of high processing temperature. As such, research for indium replacement is continuing.

 

Graphene, CNT (carbon nano tube), Ag nanowire, and metal mesh are some of the materials that are in the spotlight as ITO replacement. However, Park emphasized that transparent electrodes that are being developed at present have difficulty in surpassing ITO in terms of electronical and optical properties. Instead, he explained that as the display shape changes, the replacement material can be used for displays where ITO cannot be applied.

 

At present, ITO is being used as the main electrode material for flat display. However, its weakness against mechanical stress and limitation in flexibility led to some views that flexible display application will be difficult. Regarding this Park explained that thickness of substrate is more important than ITOโ€™s traits for displayโ€™s curvature radius and therefore if substrate becomes thinner, ITO can be applied even to foldable display as well as flexible. He added that although folding the display is acceptable, stretchable display is impossible as the properties are destroyed when pulled.

 

Park emphasized that in order for the wearable display market, including the smartwatch market, to grow, the comfort of the user is important. He reported as a human body does not conform to a specific curvature radius, to improve the user comfort, stretchable panel that can bend in diverse directions is a necessity. For this to be possible, transparent electrode that can replace ITO is required.

 

For example, watch shaped application can be replaced with stretchable display up to the strap part that wraps around the wrist. Glasses shaped application can have stretchable display for curved areas such as lenses. Also, within textiles industry, research into smart textiles through electronic circuit application is continuing.

 

As the transparent electrode that can replace ITO, Park suggested graphene and Ag nanowire complex. Ag nanowire reduces high sheet tension of graphene, and graphene prevents Ag nanowireโ€™s oxidization, complementing each other. Park revealed that โ‰ฅ90% transmittance and โ‰ค30ฮฉ/ใ… was achieved through research. He emphasized as stretchability increased to 100%, it is suitable for stretchable display.

The Opening of OLED TV Market, Starts Now

On November 25, LG Electronics and LG Display announced that they are planning to reveal OLED sculptures in various shapes such as tunnel, waves, cylinder, and others using 250 units of 55inch OLED panels at N Seoul Tower in South Korea. The sculptures will screen diverse contents with artistic merit and provide extraordinary spectacle while advertising OLEDโ€™s astonishing picture quality.

 

This N Seoul Tower OLED sculpture installation is the second OLED signage that LG Electronics revealed to the public; on November 19, LG Electronics installed โ€˜OLED Momentโ€™, a supersize OLED signage, in 2 locations in Incheon International Airport and held a completion ceremony.

 

LG Electronics is aiming to lead the OLED TV market through 2 track strategy of OLED TV price reduction and OLED promotion. At the Q2 performance announcement, they revealed their plan for aggressive marketing through OLED promotion. The successive OLED sculpture installation can be seen as a part of LG Electronicsโ€™ OLED promotion strategy.

 

This strategy is analyzed to be fairly effective. On November 3, LG electronics revealed that the October sales figure was 4,500 units which is more than twice the amount sold in the beginning of the year. At the same time, OLED TV is continually falling down. 55inch UHD OLED TV, which was priced around US$ 3,000 on amazon.com in September, fell to the current around US$ 2,000.

 

Japanโ€™s Panasonic revealed their plan to actively sell UHD OLED TV from 2016. Chinaโ€™s companies including Skyworth, Changhong, Hisense, and Konka are intending to present or release OLED TV.

 

With LGโ€™s aggressive OLED TV marketing and the increase of OLED TV selling companies, the industryโ€™s attention is on the future OLED TV marketโ€™s growth. According to UBI Research, OLED TV market is estimated to grow and record approximately 17 million units in 2020.

The last 5 years of budget for Korean semiconductor, which is a key industry for the nation, and display related industryโ€™s original technology development expenses was researched and analyzed.

 

Electronic information device sectorโ€™s expenses can be categorized into semiconductor, display, LED/lighting, and evaluation maintenance fee.

 
In 2011, 130,000 million KRW was provided as technology development expense, but since then the amount annually decreased. In 2015, the amount was 95,000 million KRW, but in 2016, it is estimated to decrease further 42% and only 55,000 million KRW is expected to be provided.

Semiconductor funding for 2015 occupies 58% of the total budget with 54,800 million KRW. Although that amount will be reduced to 35,600 million KRW in 2016, it is expected to occupy 65% of the total funding.

 

For display section, the 2015 funding is only 19,500 million KRW, a 21% of the total budge. In 2016, this is estimated to fall to 17%.

 

The government funding for display sector, which is the core of Korean electronic information industry, is around the same level as LED/Lighting sector.

 

The rapid reduction of government funding for display industry is expected to cause much difficulty in future display business.

The Korean display panel market that is being maintained by 2 companies, Samsung Display and LG Display, recorded 62 billion KRW in 2012. However, it fell to 52 billion KRW in 2014, and the market power is gradually weakening. As Chinese companies are becoming more active in LCD market, Korean companiesโ€™ price competitiveness is waning in low-priced panel market.

 

If BOEโ€™s Gen10.5 line begins operation in 2018, Korean display companiesโ€™ market power is analyzed to rapidly fall in LCD market. In order for the Korean display business to take-off again, now is the time for the government to fund OLED panel which has high added value.

ETRI Reveals Graphene Applied OLED Lighting

At R&D Korea 2015 (November 19-21), ETRI (Electronics and Telecommunications Research Institute) revealed OLED lighting and graphene related research results.

 

Since 2013, ETRI has been participating in โ€˜Graphene Applied OLED Device/Panel Technology Developmentโ€™ project as a supervising organization. This project is a part of โ€˜Graphene Device/Component Commercialization Technology Businessโ€™, which is a Korean national project. This projectโ€™s ultimate aims include development of graphene electrode material with โ‰ฅ15ฮฉ sheet resistance, โ‰ฅ90% transmittance, 3nm thickness, โ‰ค5% sheet resistance uniformity, โ‰ค5nm surface profile, and โ‰ฅ5.5 generation area, graphene based protection layer that can be used for 5.5 generation 55inch OLED panel with โ‰ค10-6 g/m2 WVTR, graphene anode OLED with โ‰ฅ90% external quantum efficiency compared to ITO anode OLED, and diagonally 1300mm OLED panel prototype.

In this exhibition, ETRI presented OLED lighting that used graphene as the electrode. ETRIโ€™s Dr. Jeong-Ik Lee explained that recently interest in graphene electrode is increasing to replace ITO electrode and to apply graphene electrode, optical, electrical, and process issues have to be considered. When graphene is used as OLED electrode instead of ITO, thickness and refractive index change optically and electrically energy levels change, and these have to be considered when designing. He also emphasized that in terms of process, it has to be designed keeping in mind of before and after process of electrode procedure. Dr. Lee revealed that at present optical and electrical issues are solved while the process issues are in research stage, and they are planning to present the results of this research within this year.

 

Graphene, with its high resistivity, is known as next generation electrode material favorable to flexible and foldable. Dr. Lee pointed out that graphene has wider viewing angle than ITO when used as transparent electrode is another important advantage, and particularly as white light sourceโ€™s spectrum cannot change according to the viewing angle, graphene is suitable for application.

 

Graphene is a key material with a wide arrange of applications, it is being developed in diverse areas such as OLED encapsulation as well as in electrode sector. The Ministry of Science, ICT and Future Planning of Korea estimated that domestic graphene market will record 19 billion KRW until 2025. Korea Evaluation Institute of Industrial Technology, the organization in charge of this national project, gave their target as developing 9 top technology through graphene and achieve 17 billion KRW sales. Regarding this, Dr. Lee emphasized compared to other countries, Korean investment in graphene is relatively low and that now is the time for the Korean corporations and government agencies to pay more attention higher value-added businesses.

AMOLED Smartphone to Exceed 200 Million Units This Year

It is anticipated that AMOLED display equipped smartphone will exceed 200 million units this year.

 

According to a market research company UBI Research, AMOLED equipped smartphone recorded 60 million units in Q3 2015, and estimated the total shipment of this year to be above 220 million units. This is approximately a 40% increase compared to last yearโ€™s result of 160 million units.

[Automotive Display Seminar] Automotive Display, Urgent Transparent Display Technology Development Needed

By Choong Hoon Yi

 

On November 13, Automotive Display Development Technology and Commercialization Planning seminar was hosted by Educational Center of Future Technology in Yeouido, South Korea.

 

KATECH (Korea Automotive Technology Institute)โ€™s Dr. Sun-Hong Park explained that โ€œas the automotive display market grows, display marketโ€™s domain is expandingโ€ and announced โ€œmarket for CID (Central Information Display) that mainly functions as navigation device and HUD (Head Up Display) that can show mileage and speed is steadily growing since 2008 and it is anticipated to grow considerably in futureโ€. He added that particularly, 7inch or larger CID is increasing its market share in display market and that CID is becoming larger. He also mentioned that with the increase of traffic accidents from driverโ€™s lack of attention to the road, HUD that can show information on the front window is necessary. However, legibility issues due to brightness and reflectiveness and technological issues such as integration with other display device need to be solved.

Dr. Chi-Sun Hwang of ETRI (Electronics and Telecommunications Research Institute) compared display technology that can actualize transparent display, and technological issues to be solved in order for it to be applied to automotive. Hwang explained that although display technology that can produce transparent display include LCD, OLED TFEL (thin film EL), HUD (projection) among others, AMOLED is the most suitable considering resolution and transmittance. Although LCD technology level is at commercialization stage, as the transmittance is not high it can interfere with the driverโ€™s viewing field. He also added that โ€œpoly Si TFT technology performance is good, transmittance is limited. However, oxide TFT technologyโ€™s transmittance is high and performance is continuing to improve, it needs to be more actively developedโ€. To be used as an automotive display, it has to meet certain conditions such as temperature, production cost, and brightness to be an automotive component as well as being placed in the suitable location in the driverโ€™s viewing field; compared to other general display, automotive display is facing higher number of technical issues.

With the focus on the transparent display from automotive display industry, the interest in the technology needed for the application to automotive is also increasing. In order to lead the automotive display market, understanding of automotive componentsโ€™ characteristics and effort to solve the diverse issues facing the optimized driving condition are required as well as knowledge of display itself.

[Expert Talk] Dr. Mauro Riva, SAES Groupโ€™s OLED/OLET Business Developer, on Encapsulation

Dr. Mauro Riva, SAES Groupโ€™s OLED/OLET business developer, discussed his views on OLED in general as well as SAES Groupโ€™s technology through his interview with the OLEDNET and presentation at the OLEDs World Summit (October 27-29) titled โ€˜The Encapsulation Questionโ€™.

 

Encapsulation is required to prevent the oxidation of emitting and electrode materials by blocking moisture and oxygen. It also protects the device from mechanical and physical shocks. The basic configurations of encapsulation can be divided into 3: glass-to-glass, barrier film lamination, and thin film encapsulation methods. Glass-to-glass configuration is applied to rigid AMOLED for mass produced mobile, barrier film lamination and thin film encapsulation methods are used for flexible AMOLED, and barrier film lamination is used for large area AMOLED panel for TV.

According to Dr. Riva OLED encapsulation is still facing the same issues it had since the beginning: OLED materialsโ€™ extreme sensitivity to oxidizing agents and moisture in particular. He added that OLED materials can also be very sensitive to heat or radiations, generating many process constraints. Encapsulation technology is directly related to the lifetime of the OLED device and Dr. Riva raised several questions regarding the current issues surrounding the technology including the appropriate target lifetime, best definition of โ€œlifetimeโ€, and reliability of the โ€œaccelerated testsโ€. He emphasized that while much progress have been made, a โ€œsingle optimal, universal solutionโ€ does not exist yet to meet various encapsulation requirements depending on OLED architecture, materials, environment, applications, etc. As such, encapsulation materials have to be specifically engineered to meet different types of OLED devices while having โ€œexceptionally high barrier properties, and active fillers or getters, capable of absorbing water on a single molecule basisโ€. Thus, perfecting this technology is a very challenging task, and, according to Dr. Riva, something that requires in depth collaboration between advance encapsulation materials providers and OLED makers.

 

For their part in this technology progression, Dr. Riva reported that SAES Group provides a very large portfolio of active edge sealants, active transparent fillers, and dispensable getters. He explained that the portfolio is the results of deep know-how in functional polymer composites (FPC), โ€œspecially tailored to address customersโ€™ specific OLED designs and processesโ€. Discussing the FPC during his talk in OLEDs World Summit, Dr. Riva emphasized the versatility of this approach.

Regarding application methods for SAES Groupโ€™s FPC products, Dr. Riva explained that they can be dispensed via screen printing, blading, syringe, ink-jetting, ODF (one drop filling), and even be employed in thin film encapsulation structures, to make them simpler and more reliable. Furthermore, Dr. Riva reported that while SAES Group considers syringe dispensing as one of the main methods for applying their FPC, โ€œink-jetting is also becoming more and more widespread, together with ODF, especially for active fillersโ€.

 

Dr. Riva believes the FPC could play an important role in making the encapsulation more effective, and that SAES Group can โ€œleverage on its advanced materials expertiseโ€ and in-depth getter/purification knowledge, to โ€œperfect FPC based encapsulation solutions for OLEDsโ€. 11% of SAES Groupโ€™s net sales is allocated to Research and Innovation every year with strong cooperation with universities and R&D centers. The company is collaborating with many companies in diverse areas of interest such as OLED lighting, manufacturing equipment, specialized food packaging, and gas barrier films. This proactive and collaborating approach will enable the SAES Group to play a key role in developing more marketable OLED devices.

[Expert Talk] OLEDWorksโ€™ Co-founder David DeJoy Talks New Lighting Experience

Through an interview with OLEDNET and his presentation during the OLEDs World Summit (October 27-29), OLEDWorksโ€™ co-founder, chairman and CEO David DeJoy discussed OLEDWorksโ€™ vision and OLED lighting.

 

OLEDWorks hit the headlines in April this year when it was announced they would acquire key OLED assets and relevant intellectual property from Royal Philips whose main OLED product is Lumiblade. This acquisition was finalized earlier this month, taking this relatively small but already dynamic player within the OLED lighting industry to another level with plans that include continuing production in both Germany and the US, and expanding the product portfolio.

 

As the worldโ€™s first area light source, OLED lighting is naturally diffusive. As the light is uniform without flickers, the glare and eye fatigue is minimized. Although it is similar to LED in that it is a solid-state lighting, OLED produces little heat and color temperature can be easily adjusted. With its thinness of the panel and no need for extra installation space, OLED lighting can bring forth new design perspectives and applications. During his talk, DeJoy commented that OLED will bring the light closer to the user and will deliver a better light experience in diverse settings including patient rooms, recovery rooms in hospitals, retail, and museums.

 

Although customer response to OLED light quality is extremely positive, DeJoy acknowledged that it is facing many challenges in entering the lighting market and divided the strategy to overcome this into โ€œthe four โ€˜Aโ€™sโ€: awareness, adaptability, availability, and affordability.

 

The โ€˜awarenessโ€™ includes education about the technology and benefits, as well as confidence in the OLED lighting technology reliability. The effort to build the OLED lighting awareness includes government partnerships such as DOE Funded Gateway Projects, and NYSERDA Demonstration Projects. Designers and architects are also increasingly turning to OLED for inspiration and source material. OLED lightingโ€™s previously mentioned advantages are closely linked to the second โ€˜Aโ€™, โ€˜adaptabilityโ€™. Its thinness, lack of heat, and no need for additional installation space mean that OLED lighting can easily be integrated into fixtures and used as a building material by being directly mounted on surfaces. On the subject of โ€˜availabilityโ€™, DeJoy emphasized that more luminaire and final products should become more available to specifiers. He added that there are many in product development but they need to get into the hands of the end user. Discussing the โ€˜affordabilityโ€™ of OLED lighting, DeJoy used OLED panel cost scenario published by the US Department of Energy which estimates that the panel price will continue to fall to reach US$10/klm, which corresponds to approximately US$100/m2, in 2025. DeJoy added that when examining the affordability of OLED lighting, the total cost has to be considered. For example, OLED lighting does not require heat sink or extra installation cost. Also, many applications do not need very high lumen output with focused beams; โ€œit is not all about $/klmโ€.

DeJoy explained that OLEDWorks long term goal is making OLED lighting adaptable and available, making it easier to change the lighting when it is broken, and be user friendly. He reported that OLEDWorks will continue to expand the product portfolio, which now includes Lumiblade, for โ€œincreased performance, additional form factors, and additional CCT options, while reducing product costsโ€. DeJoy also added that this is โ€œakin to the LED evolution and consistent with the U.S. Department of Energy forecastโ€. With their proactive and enthusiastic approach to the OLED lighting market, the industry is watching OLEDWorks with great interest. OLEDWorksโ€™ effect on OLED lighting market is expected to be significant.

In 2014, Visionox developed 570ppi RGB AMOLED panel with newly developed pixel structure, Z-Type. This Z-Type arrangement had larger blue sub-pixel with green and red sub-pixels beside it. The new panel has resolution of 604ppi which is a 35ppi increase from the 2014 panel. With this new reveal, Visionox displayed their high resolution OLED technology improvement.

 

The 604ppi panel combined the self-developed pixel layout under proprietary intellectual property rights and co-developed Chinese FMM. The resolution is 2,560 ร— 1,440, manufactured using real RGB method and not pentile.

 

Chinese companies are developing their high resolution AMOLED panel technology at a fast pace. In August, EverDisplay presented 734ppi 6inch panel, and the technology difference with Korean panel companies is rapidly decreasing.

 

Visionox revealed that this OLED panel shows Visionoxโ€™s research development for high resolution OLED is continuing and aptly demonstrated the current results.

[IWFPE 2015] What Will Replace ITO?

2015 IWFPE (International Workshop on Flexible & Printable Electronics) was held at Le Win Hotel in Jeonju, South Korea (November 4-6). During the workshop, many OLED display related presentations commented on ITOโ€™s replacement material.

 

Dr. Jennifer Colegrove, CEO of US research company Touch Display Research, discussed hot trends of 2015-2016. Dr. Colegrove included high resolution, transparent display, wearable device, and flexible display in the hot trends. Of these she pointed out ITO replacement material regarding touch panel. She mentioning metal mesh, silver nanowire, CNT, and graphene as materials that could replace ITO. Dr. Colegrove added that the material has to be flexible in order to be applicable to flexible display and needs to have high efficiency.

 

๊ทธ๋ž˜ํ•€

 

Hanwha Techwinโ€™s Dr. Seungmin Cho announced that graphene, which has higher uniformity compared to ITO, will be the material of future. With lower resistance than ITO, graphene shows good characteristics, but Dr. Cho explained that high cost and particles produced are issues that need to be solved. He also commented that China selected graphene related national projects and is striving to develop the technology.

 

Dr. Hyunkoo Lee of ETRI (Electronics and Telecommunications Research Institute) presented that the multi-layered graphene that ETRI, Sungkyunkwan University, and KAIST (Korea Advanced Institute of Science and Technology) co-developed will become the material that can replace ITO. He also introduced the results that as the transmittance is particularly high, it is suitable for transparent display, and compared to silver nanowire material in high resolution top emission structure, the displayโ€™s brightness is higher.

 

ITO replacement development is an issue for the future of display industryโ€™s progress. It is estimated that research development on graphene as one of the ITO replacement electrodes will be actively carried out.

[Merck Display Insight 2015] Merck Reveals Latest Performance Results for Red and Green Solution Process Materials

On November 5, during the 16th Merck Display Insight 2015 seminar, Merck revealed the development results for solution process materials. The solution process materials presented were red and blue materialsโ€™ efficiency, lifetime, and CIE.

 

At present UDCโ€™s evaporation materials are being used in OLED mass production. UDCโ€™s evaporation material performance, published on the company website, were compared with Merckโ€™s materials. Merckโ€™s red materialโ€™s efficiency was 19.1cd/A, lifetime was 5,900 hours, and the CIE was (0.66, 0.34) which were approximately 66% of UDC materialโ€™s efficiency (29cd/A), 26% of UDC materialโ€™s lifetime (23,000 hours), and showed equal CIE.

 

For Merckโ€™s green material, efficiency was 76.4cd/A, lifetime was 5,200 hours, and the CIE was (0.32, 0.63). These were approximately 89% of UDCโ€™s greenโ€™s 85cd/A of efficiency, and 29% of 18,000 hours of lifetime. The CIE were similar with UDCโ€™s (0.31, 0.63).

 

The comparison of the published materialsโ€™ performance, efficiency of solution process materials are developed to the similar levels as evaporation materials, but material lifetime require more research. Through this seminar, Merck revealed that the LT95โ€™s solution process materialโ€™s lifetime will be solution process OLEDโ€™s most crucial challenge.

 

During the question and answer part of the poster session, Merck also revealed positive outlook that full stack solution process OLED product will be produced within the next 3-4 years.

 

Despite being one of the latecomers within the OLED material business, Merck is producing notable results in solution process material development and OLED material sales. This yearโ€™s sales results are anticipated to be higher than expected.

 

According to 2015 Solution Process OLED Annual Report, published by UBI Research, the key issue for solution process OLED is solution process emitting material performance. The solution process red and greenโ€™s efficiency reached to the similar levels as evaporation material. However, lifetime showed to be โ‰คapprox. 30% of evaporation material in LT95. On the other hand, solution process blue is analyzed to be falling behind evaporation material in both lifetime and efficiency. As such, it is estimated that solution process OLED will be mass produced using the hybrid structure where red and green are formed through printing, and blue is formed through evaporation.

[IWFPE 2015] AUOโ€™s Bendable AMOLED

During the IWFPE 2015 (November 4-6) held in Jeonju, South Korea, AUO gave a presentation on bendable AMOLEDโ€™s concept and technology first revealed in August.

 

AUOโ€™s R&D manager Terence Lai reported that the bendable AMOELD can actualize new user interface through applying displayโ€™s bending characteristics and this can be the innovation that could change the existing touch interface.

 

AUOโ€™s bendable AMOLED is 5inch with 295 PPI using the LTPS TFT and hybrid encapsulation with top emission structure. It has 02.mm thickness and through bending sensor of file type, it can process diverse functions by detecting different bending directions.

 

Current flexible AMOLED trend is moving from curved to foldable, jumping past bendable. Key panel companies and research laboratories are focusing on developing foldable.

 

It is anticipated that the AUOโ€™s bendable AMOLED panel will provide new direction for the flexible AMOLED development that is heading toward foldable. Development of applications suitable to bendable and functions that utilizes bending characteristics are expected to be key issues.

LG OLED TV Records Highest Monthly Sales Volume

LG Electronicsโ€™ strategy of OLED promotion and OLED TV price reduction appears to be working successfully.

 

On November 3, LG Electronics reported that the October sales exceeded 4,500 units, twice the volume of early 2015. Particularly, the sales volume of the first week of October exceeded 2,000 units and contributed to breaking the monthly sales volume record.

 

The OLED TVโ€™s bigger price drops from the last week of September seem to have led the high sales volume in the first week of October. According to Amazon, 55inch FHD curved OLED TV fell to US$ 1,797 from October, approximately a 28% drop from Augustโ€™s US$ 2,499. 55inch UHD curved OLED TV and UHD flat OLED TV also fell to the US$ 2,000 range, making the price difference with UHD LCD TV to be US$ 500. This price competitiveness is analyzed to contribute to the increased sales volume.

 

Aggressive marketing is also a factor for this sales volume growth. In September, LG Electronics installed OLED TV in 39 key airports in 23 countries including the US, Germany, and Russia, and revealed plan to install approximately 200 units of OLED TV until the end of October. Advertisement of OLED TV can also be easily seen in Korean subway stations. LG Electronicsโ€™ OLED promotion strategy, revealed during the Q2 performance announcement appears to be effective.

 

Recently, LG Electronics announced their aim to lead the OLED TV market through strengthening OLED=LG image and OLED TV and UHD TV product diversification.

LG Electronics Strives to Establish OLED=LG Image

On October 29, during the performance announcement, LG Electronics revealed their plan to carry out aggressive marketing through establishment of OLED=LG image.

 

LG Electronics Home Entertainment business reported that the TV shipment doubled in this quarter compared its previous quarter due to OLED TV and UHD TV product mix. LG Electronics reported that OLED TV market expansion from Korea and North America into Europe and Russia among others contributed to the sales increase.

 

LG Electronics is anticipating sales increase in Q4 from peak TV market and general market promotion brought premium TV sales expansion. Accordingly, LG Electronics forecast their Q4 sales to be similar to 2014 and that business profit to increase slightly due to improvement in TVโ€™s profit stabilization.

 

Regarding aggressive marketing from Chinse TV companies including Hisense, and TCL, Jinho Ha of LG Electronics Home Entertainment planning department, admitted the threat. However, through premium TV technology such as smart TV, design, and OLED, Ha explained that they will secure product superiority. He also added that Chinse companiesโ€™ North American TV market share is around 3% in terms of volume and remains minimal in revenue.

LG Display Reveals Confidence in OLED

On October 22, LG Display emphasized their conviction in large area OLED and plastic OLED once again when announcing the performance results held in LG Twin Towers. LG Display revealed that their future business will be OLED and will lead the market through OLED.

 

LG Displayโ€™s CFO Sang-don Kim announced that OLED is the top priority in terms of portfolio, and regarding displayโ€™s future direction, explained that there is new momentum through automotive, IoT, and commercial display. He also added that the sales did not quite meet what was estimated earlier this year but it is on proper track.

 

LG Display is estimating 400-500 thousand units of OLED TV panel shipment for TV and aiming for 1 million units next year. Regarding the poor sales, he gave trial errors in new technology development, which was the main focus, as the reason. LG Display will plan optimized investment after market trend consideration.

 

In 2015, 55inch or larger panel for TV occupied 8% of the shipment, but the target is gradually increasing it to 20% or higher. LG Display highlighted TVs are becoming larger at a fast pace; 65inch and 77inch OLED TV, rather than what was expected to be the main product 55inch, showed higher than expected sales. Kim explained that to maximize production cost reduction of OLED panel, they are internally adjusting material cost and yield. He also forecast that the demand will increase through production increasing projects.

 

LG Display recorded 7,000 million USD* of revenue in 2015 Q3. This 7% increase compared to its previous quarter is due to the increase of shipment area through TVโ€™s panel size increase and success of product mix. Business profit fell by 32% compared to previous quarter with 300 million USD*. LG Display revealed they will push for profit improvement through inventory level management and operation rate adjustment. They also reported they will strengthen competitiveness through synergy with OLED lighting business and showed anticipation for future.

Absolute Requirements for the Automotive OLED Displayโ€™s Success

On October 15, in IMID Exhibition Business Forum held in Korea International Exhibition Center (October 14-16), KATECH (Korea Automotive Technology Institute)โ€™s head of Intelligent Control System R&D Center Dr. Inbeom Yang presented โ€˜Future of Automotive Technology and the Role of Smart Displayโ€™ and forecast the future of automotive display.

 

Dr. Yang revealed that โ€œif existing vehicles focused on technological factors, future vehicles will evolve entirely centering on the driver, and the automotive display also will develop following this trendโ€. He also added that the driverโ€™s safety and convenience have to be the priority.

 

Dr. Yang gave 4 examples of future automotive display. Firstly, he discussed ADAS and their flaws. ADAS (Advanced Driver Assistance Systems) help the driver to operate the vehicle safely. If ADAS can be actualized through displays such as HUD (head-up display), the driverโ€™s safety can be maintained with ease.

 

The second item mentioned was a function that notifies the driver status reports linked with time and location. Dr. Yang reported that a device needs to be developed that can function in specific situations with sensors and sounds as well as on display.

 

Dr. Yang forecast that if display, touch technology, and haptic technology are combined and applied to vehicles, operation and feedback will be simpler for the driver. He announced that multi-functional & configuration display will also be introduced which will allow driver to recognize and control.

 

Audiโ€™s concept vehicleย that was presented in IAA 2015 Audi e-tron quattro has full OLED interface and all functions required for the vehicle operation can be controlled via touch display without physical buttons.

 

As futuristic displays such as these are developed that increases driverโ€™s convenience, the proportion of display within a vehicle is expected to increase, and developed focusing on the driver centered UI (user interface). OLED Display can maximize the driverโ€™s accuracy with fast response rate and high contrast ratio. Along with safety, and design freedom that comes with flexibility, it is suitable for automotive display. However, the linkage with the UI system optimized for the driver is essential rather than performance of the display panel itself; collaboration between display panel companies, and automotive system and peripheral companies is expected to be a major point in early market occupancy between automotive display panel companies.

LG Electronics Bets on OLED TV

LG Electronics actively began aggressive marketing for OLED TV.

 

In IMID Exhibition (October 14-16), LG Electronics installed an OLED comparison experience zone to allow the visitors to see OLED TV and LCD TV at once. This direct comparison exhibition with OLED and LCD is the 2nd one after one in WIS 2015. In this exhibition in IMID Exhibition 2015, LG Electronics presented their new 2015 release 55inch UHD LCD TV and 55inch UHD OLED TV. This is considered a reflection of LG Electronicsโ€™ determination to target the market through OLED TV rather than LCD TV.

 

LCD TV is illuminated through BLU and therefore difficult to achieve perfect black. Through IMID Exhibition 2015โ€™s comparison experience zone, LG Electronics emphasized OLED TVโ€™s merits such as perfect black, perfect viewing angle, and ultra slim design.

 

Since the release of OLED TV, LG Electronics continued presentations that emphasized OLED TVโ€™s advantages in diverse exhibitions. However, recently they are pursuing aggressive promotion focusing on OLED even exhibiting comparison against their own latest LCD TV. On the other hand, their rival Samsung Electronics is maintaining their 2-track strategy of using OLED and LCD in different applications each. The industry is focused on how these development will affect the large area TV market.

Samsung to Increase External Transaction by More Than 30%

Samsung Electronics reported a third-quarter earnings through a conference call on October 29 local time. Samsung Displayโ€™s Chang Hoon Lee revealed that OLED panelโ€™s production cost can now compete against LCD and the company has plans to increase the external transaction ratio by more than 30% of yield.

The display business department was expected to have a difficult time in Q3 2015 due to the smartphone marketโ€™s slowdown of growth and latecomersโ€™ competitiveness increase. However, with the key customer baseโ€™s release of new products and increase of new clientele, and secured operation ratio, the performance results improved.

Lee also revealed 2016 strategy of increasing the low-to-medium priced products, expanding the new market, diversifying products, and procuring transaction base. Lee also added that Samsung will prepare to secure new growth power through transparent, mirror, HUD, and automotive display development via technology leadership in areas such as flexible OLED.

It was also announced that the additional installation of OLED line will be decided after examining the market status. A3 line has been in operation since April. Supply competitiveness will be strengthened through complementary investment for existing line.

Samsung Electronics recorded a 6% increase compared to the previous quarter with revenue of USD 47 billion. With the help of currency exchange rate, business profit showed approximately USD455 millionย compared to the previous quarter with USDย 6.7 billion.

Samsung and LGโ€™s Shared Vision for OLED

On the first day of OLEDs World Summit (October 27-29) held in Berkeley, USA, Samsung Display and LG Display gave their talks back to back. Samsung Displayโ€™s Vice President Chang Hoon Lee and LG Displayโ€™sย Joo Soo Lim discussed their thoughts on OLED under the titles of โ€˜The Future of OLEDsโ€™ and โ€˜A Future Game Changerโ€™ respectively.

Samsung Displayโ€™s Lee, who gave his presentation first, reiterated Samsung Displayโ€™s leadership position in the mobile market and how Samsung Electronicsโ€™ recent mobile display reflects this. Comparing RGB pixel structure and their own diamond pixel structure, Lee drew comparison between human eyes and diamond pixels; due to cell distribution in eyes, humans are more sensitive to green colors and that diamond pixels reflect this by having twice as many green subpixels as blue and red ones. The diamond pixels also maximize the sub-pixel packing and increases the PPI.

Regarding the advantages of OLED display, Lee gave 2 examples using Samsung Electronicsโ€™ latest smartphone models. Utilizing the fact that selective control of each pixel is possible in AMOLED displays, Samsung provided Vision Aid to help people with color blindness. OLEDโ€™s ability to achieve total black is used in Super Dimming function where screen brightness can be reduced to 2nits to be used in the dark environment.

LG Displayโ€™s Lim revealed that an adult in the US spends 9 hours 40 minutes a day on average looking at one form of display or another. Highlighting the need and importance of quality display, Lim also discussed advantages of OLED display over LCD such as total black, 3D effects, and color gamut.

As the future OLED display, Both Lee and Lim placed slightly more emphasis on flexible (plastic) OLED than transparent or mirror display. Samsung Display discussed requirements necessary for a successful flexible display in more depth touching on the need for suitable cover window, flexible touch (sensor), flexible encapsulation, and flexible backplane. On the other hand, LG Display discussed flexible displayโ€™s design freedom and its influences on the wearable, mobile, and automotive markets. Lim also placed much importance on how flexible OLED can be used in virtual reality display market. The 2 speakers ended their talks affirming the need for new display market and innovation through OLED technology and new applications.

The presentations given by the 2 apparent leaders in the OLED display industry were remarkably similar with both speakers underlining major points of OLED in broad strokes. The need for solutions for future OLED, whether it be flexible, transparent, or mirror display, through innovation and technological advances is an absolute truth if not maybe too obvious. There also may be some comfort to be had in the shared vision within the OLED community. However, it is also a fact that numerous attendees of the conference commented on the similarities of the 2 presentations and the lack of any surprises.

What is Solution Process OLEDโ€™s Key Issue?

In the 2015 Display Printed Electronics Seminar held in The K Hotel in Seoul on October 7, Dankook Universityโ€™s Professor Byung Doo Chin and Korea Research Institute of Chemical Technologyโ€™s Dr. Jaemin Lee gave presentations. They discussed key issues of solution process OLED; Professor Chin examined technological issues of print OLED/PLED device while Dr. Lee discussed technology trend of solution process OLED device.

 

Professor Chin reported that of the materials being used in current solution process, red, and green progressed greatly in terms of efficiency and lifetime. However, he explained that as blueโ€™s efficiency and lifetime are lower than the other 2 colors, unless these issues improve, white actualization, as well as blue actualization, is difficult and panel cannot properly perform.

 

Material research development can occur for evaporation OLED only through material synthesis and purification. However, for solution process OLED, turning the materials to ink has to be additionally considered. Dr. Lee announced that diverse collaboration are happening between material and ink related companies for these reasons.

 

In the seminar, Professor Chin and Dr. Lee agreed that the key to the solution process OLED development is material characteristics development. According to the solution process material traits presented by Sumitomo Chem. and DuPont, while red and green traits are fast catching up to ones used for evaporation OLED, this is not true for blue. Despite these disadvantages, solution process OLED is a key technology that can produce large area RGB OLED panel using Gen8, or higher, manufacturing equipment; continued research development of solution process technology is expected in future.

Samsung Display Expands AMOLED Panel Supply. A Green Light for AMOLED Business?

On October 7, Samsung Electronics announced tentative Q3 performance results. The announced sales figure and operating profit are approximately US$ 46,000 million and US$ 7,000 million each. These figures are an increase of 5.07% from previous quarterโ€™s sales (US$ 44 thousand million) and a 5.8% increase from previous quarterโ€™s operating profit (US$ 6,000 million), much higher numbers than industryโ€™s expectations.

 

Compared to the same period in 2014, operating profit increased by 79.80%, and since last yearโ€™s Q4, the rise is continuing for the 4th quarter. The display business departmentโ€™s much higher figures than expected is considered to be the main reason for this performance increase.

 

The major cause for this positive effects is increase in demand for general class AMOLED panel through Samsung Displayโ€™s aggressive procurement of customer base; AMOLED panel is applied to Samsung Electronicsโ€™ mid to low priced smartphones and there is great increase in AMOLED panel applied products by set companies of other countries such as China.

 

Due to the increased demand, Samsung Displayโ€™s operation rate rose, and it is estimated that this will also greatly affect material companiesโ€™ performance improvement.

Solution Process Panel, Cheaper To Produce than LCD

According to 2015 Solution Process OLED Report, published by UBI Research on October 14, solution process technology could produce 55inch OLED panel at approximately 43% cheaper cost compared to WRGB method.

 

The report added that this value is the result of analysis of 2015 Q2 55inch UHD OLED panel price and yield, which is slightly higher than current production price of 55inch UHD LCD panel. However, considering that the solution process OLED structure will become simplified and that yield of backplane and encapsulation can be improved, the OLED panels will be able to be produced at lower cost than LCD panel. The report also revealed that solution process OLED can be an alternative solution for large area OLED panel in achieving price competitiveness.

 

Solution process is a technology that can produce large area RGB pixel OLED panel using Gen8, or higher, equipment without cutting the mother glass. Key AMOLED panel companies are active in developing this technology.

 

However, as solvent is used in order to turn the existing evaporation material into ink, its purity is decreased leading to lower emitting efficiency and therefore lower lifetime. Despite these factors, key panel companiesโ€™ enthusiasm for solution process technology is due to the high emitting material usage efficiency without using color filter, and simple structure compared to WRGB OLED panel which leads to production cost decrease.

 

Panasonic has been most active in developing solution process applied OLED panel, and has presented several times in CES and IFA. BOE and AUO also have revealed solution process OLED panel produced via ink-jet manufacturing equipment, and CSOT is considering solution process development. Samsung Display and LG Display, leaders of AMOLED industry, are also actively developing the technology. LG Display has adopted Gen8 ink-jet manufacturing equipment, and Samsung Display has started solution process OLED panel development with a focus on ink-jet manufacturing equipment companies.

 

Material and manufacturing equipment companies as well as panel companies are leading the solution process technology development and commercialization. Kateeva agreed on technology collaboration with Sumitomo Chem. while Merck did the same with Seiko Epson. DuPont recently revealed that they enlarged solution process OLED material production facilities and began operation.

 

Following these participation by key panel, material, and manufacturing equipment companies in solution process technology development and commercialization, it is anticipated that the solution process OLED panel market will record rapid growth.

 

UBI Researchโ€™s 2015 Solution Process OLED Report forecast that solution process OLED panel market will actively begin mass production from 2018 and show approximately US$ 2,329 million in 2020.

LG Chem.โ€™s OLED Lighting Business Toward LGD. What is the Future Direction?

It was announced that LG Display will take over LG Chem.โ€™s OLED lighting business department. As the department that was leading the opening of OLED lighting panel market is being merged into LG Display, a significant change in OLED lighting industry is anticipated.

 

One of the merits of this merge is expected to be further improving OLED lighting panelโ€™s mass production potential through LG Displayโ€™s existing OLED panel mass production line, labor, and technology. Additionally, when new investment of OLED lighting panel mass production line is being processed, time and cost can be reduced on the basis of LG Displayโ€™s manufacturing equipment/material supply chains.

 

On the other hand, as OLED lighting market is still in initial stages the size is not so large. As such, whether LG Display will newly invest is a key issue. Generally, for display panel companies that invest with market size of thousands of millions of dollars in mind, OLED lighting panel lineโ€™s new investment does not seem to have a great advantage for LG Display.

 

Therefore, if LG Display carries out OLED lighting panel business, the first step is estimated to be mass production in parts of Pajuโ€™s AP2 line rather than new investment for OLED lighting panel mass production line. If parts of AP2 line begin mass production first, mass production timing can be much sooner than new investment and can positively affect expansion of OLED lighting panel market.

 

The issue is marketing strategy. In 2009, Samsung Electronics successfully opened AMOLED smartphone market in Korea via push strategy using AMOLED themed music video that became viral. Much like this, in order to show profit in OLED lighting panel business, LG Display should open the market through push marketing strategy.

Samsung Display Shows OLED/LCD Confidence in IMID

In IMID Display 2015 Business Forum (October 14 โ€“ 15), Samsung Display Vice President Hak Sun Kim gave a presentation titled โ€˜New Experience with Large Screen LCD/OLEDโ€™ and discussed Samsung Displayโ€™s technological points and strategy regarding OLED and LCD.

 

Kim emphasized that in the current large area display panel market LCD and OLED should be approached through different points of view and strategies; LCD requires additional value on top of existing technology and OLED should develop a new market that LCD cannot reach.

 

At present, LCD is catching up to OLED in large area panel through diverse technology development. Kim revealed that the key factors in large area LCD panel are immersion and realism. Immersion can catch up to OLED through curved technology, and realism can be matched through contrast increasing technology.

 

Regarding OLED, Kim mentioned transparent and mirror OLED display, developed by Samsung Display, as examples and stressed that future displayโ€™s worth when switched off will become important. Different from LCD, OLEDโ€™s transmittance and emitting areas can be separated and increase the transmittance value above that of LCD; when applied to transparent display, adequate transmittance can be achieved. Additionally, when used as mirror display, OLEDโ€™s transmittance and reflectance act independently which makes it more suitable in application compared to LCD where the two act in inverse proportion.

 

In this IMID Display exhibition, Samsung Display presented 55inch ultra-slim UHD curved TV, transparent, and mirror OLED display simultaneously. It is estimated that Samsung Display will continue their 2-track strategy where they reveal both OLED and LCD in different applications. On October 14, Dong-gun Park, CEO of Samsung Display, announced that they will strive to continue leading the market through unrivaled OLED and LCD technology prowess.

TAG Heuer to Unveil Smartwatch Worth $1,800

On September 29 (local time), the TAG Heuer CEO, Jean-Claude Biver, told CNBC news that they will unveil their Android-powered smartwatch on November 9 at the LVMH building in New York. The announced price for the connected watch is $1,800.

 

The watch, Carrera 01, is produced by TAG Heuer, French luxury group LVMHโ€™s biggest watchmaker, using Googleโ€™s Android OS in a venture with Intel. Biver told CNBC that could not have had better partners than Intel and Google for their first smartwatch. He also revealed he loved the Apple-Hermes deals because it showed that the smartwatch has cracked the luxury market.

 

“We were a little bit concerned about the price, because we’re going to sell it at $1,800 … and now we are quite reassured because Apple is telling us we can sell at $1,500 or even more,” he said. “I’m very, very pleased.”

 

Biver also told CNBC that TAG Heuer would not try to chase Apple but instead chase Swiss watch industry.

 

DuPont Displays Opens OLED Materials Scale-Up Facility for Next Generation TVs

On 30 September (local time), DuPont Displays announced the opening of a state-of-the-art, scale-up manufacturing facility designed to deliver production scale quantities of advanced materials that enable large-format, solution-based printed OLED displays.

 

These materials are designed to help manufacturers develop OLED displays that are brighter, more vivid, longer lasting and significantly less expensive than the OLED TVs on the market today.ย  The facility is located at the DuPont Stine-Haskell Research Center (Stine-Haskell) in Newark, Del., near DuPontโ€™s global headquarters in Wilmington, US.

 

DuPontโ€™s new scale-up facility is sized to meet the future growth expectations of the OLED TV industry, which analysts predict will increase by over 70 percent for the next several years and will require large quantities of highly sophisticated OLED materials. This new OLED facility at Stine-Haskell has large-scale formulation systems and can support simultaneous production of multiple product lines.

 

โ€œMaterials are critical to the performance of an OLED TV and we are confident that DuPont has the best performing solution OLED materials available in the market today,โ€ said Avi Avula, global business director, DuPont Displays.ย  โ€œOur vision is that OLEDs will become the display standard and to make that vision a reality, we are focused on helping our customers bring the cost of large sized OLED TVs down to less than $1000 by 2020.โ€

LG UHD OLED TV Price Falls Once More

The price of OLED TV by LG Electronics is falling fast. The 55inch flat UHD OLED TV (55EF9500), released last month, fell to $3,999 in 3 weeks, a 27% decrease from the initial $5,499. This price decrease is much faster than that of LG Electronicsโ€™ curved model of 55inch UHD OLED TV released in April.

 

Samsung Electronicsโ€™ 55inch SUHD TV, UN55JS9000, showed approximately over $2,500 price difference in comparison with 55EF9500 between the 1st week and the 2nd week of September. However, in the 3rd week, UN55JS9000 and 55EF9500 each showed 4% and 15% of decrease rate to record $2,497 and $3,999 respectively, with approximately $1,500 difference. This is the highest reduction rate for LG Electronicsโ€™ OLED TV.

In addition to the price reduction, LG Electronics is marketing their products aggressively. They are in the process of installing OLED TV this month in 39 key airports in 23 countries including the US, Germany, and Russia, with plans to install approximately 200 units of OLED TV by the end of October.

LG Curved OLED TV, IMID 2015

[IAA 2015] Audi and Porsche, Propose Future Models of Smart Car

At IAA 2015 (September 17 โ€“ 27), Audi and Porsche presented OLED lighting and display equipped vehicles.

 

In the past, Audi has proved OLED technologyโ€™s excellence through diverse models and demonstrations, including introduction of โ€˜swarmโ€™ in 2013 with its 3D OLED car rear lighting panels. At this motor show, Audi revealed Audi e-tron quattro, the first concept car with Matrix OLED technology. As well as the Matrix OLED lighting, interior OLED display was also applied to the concept car. Audi explained that the Matrix OLED lighting, which was applied to the rear lighting, can continuously change lights and does not cast shadow. Full OLED interface was also applied to the car and all functions required in driving can be control by display touch. Audi revealed that they will gradually apply these technology to next generation Audi series.

 

Porsche presented their first four-seat electric sports car Mission E as a concept model. The instrument cluster for this concept car is displayed virtually in OLED. The menu can be activated through buttons on the handle. It can also be automatically activated as the clusterโ€™s eye tracking system can perceive the driverโ€™s attention. The display also follows the seat position and body attitude of the driver in what is known as a parallax effect; the display moves according to the driverโ€™s posture for easier viewing. Porsche revealed that Porsche Car Connect technology will also be applied which will allow the user to control key functions of the vehicle through a smartphone.

 

As OLED using lighting and display are actively applied to smart cars, attention on the automotive OLED is also increasing. At the National Research Development Industry General Workshop, held in July 2015, Samsung Display and LG Display each stated their thoughts on display that will be applied to future smart cars.

 

Samsung Displayโ€™s executive director Hye Yong Chu asserted that smart is displayโ€™s future, including smart car. She also explained that for the actualization of smart technology, other ancillary smart technology, such as eye tracking and voice recognition technology, are required.

 

Yoon Sooyoung, LG Displayโ€™s vice president, stated that automotive display can be used for CID, dashboard, cluster, and window, and that the development of transparent and flexible technology is necessary.

 

During the keynote session of IMID 2015, Munhyun Kim of Hyundai Motors revealed that OLED panels will mainly be applied to smart car compared to LCD as it can easily be flexible. He also added that the automotive OLEDโ€™s percentage within the total OLED market will increase, and anticipated that it will exceed 30% in 2017.

Q2 AMOLED Market, the Largest So Far

According to UBI Researchโ€™s Weekly OLED Analysis Report, Q2 AMOLED panels recorded the largest shipment and sales so far. With 56 million units, the Q2 shipment increased by 35% in comparison with Q1, and a 19% increase compared to the same period last year. US$ 2,800 million was recorded for sales, which is a 65% increase compared to its previous quarter.

 

Last quarterโ€™s AMOLED market growth is due to Samsung Displayโ€™s AMOLED panel supply volume for Chinese set companies and increase in LG Displayโ€™s flexible OLED panel production for smartwatch.

Hon Hai Precision, Actively Participating in AMOLED Panel Business?

On September 9, Tera Semicon Corporation announced the agreement with Taiwanโ€™s Hon Hai Precision to supply AMOLED manufacturing equipment worth approximately US$ 79,000 million*. Tera Semicon mainly supplies OLED crystallization equipment for poly-Si and curing equipment

 

Hon Hai Precision is a world leading manufacturing company that began as an electronics component manufacturing company in the 1970s and became a contract manufacturer in the 2000s. Hon Hai Precision is better known to consumers as its subsidiary company as well as its trade name, Foxconn.

 

Hon Hai Precision has been consistently preparing for OLED panel production. Hon Hai Precisionโ€™s subsidiary company Innolux took over Chimei, which has technology to mass produce OLED, and in 2013 announced plans to establish OLED R&D center in LCD factory operated jointly with Sharp. Additionally, in September 2014, Hon Hai Precision mentioned that they will actively begin flexible AMOLED panel development aiming to mass produce in 2016.

 

This order for Tera Semicon Corporation is analyzed to be in consideration of Appleโ€™s application of flexible AMOLED panel for iPhone series. Apple is Hon Hai Precisionโ€™s best client; of the total manufacturing products iPhone occupies 18% and iPad 17%.

 

At present, Samsung Display and LG Display are the only companies capable of flexible AMOLED panel mass production, with AUO and Japan Display perhaps joining the ranks in the next 2-3 years. With this Hon Hai Precision AMOLED manufacturing equipment order, heated competition for flexible AMOLED panel supply is expected.
