Fierce Price Competition Amongst WOLED TVs, QD-OLED TVs, and Neo QLED TVs

/in , /by

 

We experienced fierce price competition in the first half of 2022 among premium TVs with a launch price of $2,000 or more. It will be interesting to see how the Amazon Prime Day event scheduled for July will affect TV prices.
2022 OLED TV prices until June 2022 was analyzed based on 65 inch TVs. The standard was the selling price on Bestbuy.com and Sony’s QD-OLED TV selling price on their official website.
LG Electronics’ WOLED TVs B2, C2, and G2 released in March were $2,300, $2,500, and $3,200, respectively. Samsung Electronics’ QD-OLED TV S95B was $3,000. Sony’s WOLED TV A80K was priced at $3,800 and QD-OLED TV A95K was priced at $4,000.

In June, the price of LG Electronics’ G2 model fell by $200, forming a price difference of $500 for each series. Samsung Electronics’ S95B model continues to maintain a price difference of $200 lower than LG Electronics’ high-end model G2. Sony lowered the price of the WOLED TV A80K by $300, while maintaining the price of QD-OLED TV A95K.
Samsung Electronics’ S95B and LG Electronics’ high-end OLED TV G2 are in heavy price competition. Sony is setting the price of QD-OLED TV higher than WOLED TV.
The price competition is also fierce between OLED TVs from each set makers and Neo QLED TVs with Samsung Electronics’ mini-LED technology.
As of June, the prices of Samsung Electronics’ 4K Neo QLED TVs, QN85B, QN90B, and QN95B, are $1,800, $2,600, and $3,300, respectively. The 8K Neo QLED TVs QN800B and QN900B are $3,300 and $4,800.

The prices of Samsung Electronics’ 4K Neo QLED TV series and LG Electronics’ 4K OLED TV series are similar. Within Samsung Electronics’ entire TV series, QD-OLED TV is located between 4K Neo QLED and 8K Neo QLED. Sony’s OLED TV series, which is highly evaluated in terms of picture quality, is competing in price with Samsung Electronics’ 8K Neo QLED TV series.
Although this price trend is expected to continue this year, aggressive marketing following the Amazon Prime event in the second half of the year and the Qatar World Cup is expected to be strong variables. Attention should be paid to how LG Electronics’ OLED TV with micro lens array technology, which is expected to be released next year, will affect the premium TV market in the future.

OLED Smartphone Launch Products Slows Down In The First Half of 2022

/in , /by

The number of OLED smartphone launches, which had steadily increased from 2019 to 2021 reached only 110 units in the first half of 2022. 137 units had been released in 2019, 166 units in 2020, and 225 units in 2021. If this industry trend continues in 2022, OLED smartphones expected release will only be similar to 2021 or even slightly fewer than it had been last year.
Most of the smartphones released in the first half of 2022 were made in China. 98 products from China accounted for 89% of market share, followed by 9 products from Korea, 2 from Japan, and 1 from India.
By size, 6.6-inch products were the most with 34 types, followed by 6.4-inch products with 31 types and 6.7-inch products with 21 types. The largest sized product was Vivo’s ‘X Fold’, which was an 8.03-inch foldable. Not including the foldables, Vivo’s ‘X Note’ was the largest at 7.0 inches. The smallest product was Sony’s ‘Xperia 10 IV’, which was 6.0 inches.
By design, 102 types of punch hole models were released, with 4 narrow bezel types, 2 notch types, and 2 UPC types. There were two types of smartphones with UPC (Under Panel Camera) applied: ZTE’s Axon 40 Ultra and Nubia Red Magic 7 Pro.

By resolution, 51 products with 300ppi range, 50 products with 400ppi range, and 9 products with 500ppi or higher were released. No products under 300ppi were released. The product with the highest resolution was Sony’s ‘Xpeia 1 IV’, which had a resolution of 643ppi.
There were three foldable phones released in the first half of the year: Vivo’s ‘X Fold’, Honor’s ‘Magic V’, and Huawei’s ‘Mate Xs2’. All three types of foldable phones have a punch-hole design. The resolution of ‘Mate Xs2’ was 424ppi, which is 10ppi higher than the average OLED smartphones released in the first half of the year. Whereas ‘X Fold’ and ‘Magic V’ were two products with the lowest resolution among OLED smartphones released in the first half of the year.

 

Merck, now it is time to consider the refractive index of common layer materials.

/in , /by

At the ‘OLED settlement seminar for the first half of 2022’ held at COEX on June 23, Merck’s Kim Jun-ho, head of research institute, said, “The concept of the refractive index of the emitting layer is often applied to the capping layer on the cathode, but now it is also required for HTL” and mentioned that the light extraction efficiency can be improved through the optimized refractive index design of HTL.

Next, Kim said, “Because the refractive index of HTL has a trade-off relationship with the hole transport capacity, it is difficult to adjust the refractive index,” and “Even though it was lowered to 1.77 from 1.85, the light extraction efficiency could be improved by 7% without an increase in the driving voltage or a decrease in electron mobility.”

Recently, panel makers are continuously developing the OLED light extraction efficiency. This is because by increasing the light extraction efficiency, as a result, the battery life can be increased. Representative examples include a high-refractive capping layer and micro lens array, and an on-cell film that removes the polarizer and uses a color filter.
The concept of the refractive index of the light emitting, which had been concentrated on the capping layer, is extended to the common layer, and it is expected that panel makers will intensify technological competition, and that there will be many changes in the supply chain of emitting materials of panel makers in the future.

 

Choong-Hoon Yi, CEO of UBI Research, “Korean display companies must have price competitiveness as well as OLED technology competitiveness”

/in , /by

 

Although there is still a gap in display technology between Korea and China, it has been argued that Korean display companies should have price competitiveness as soon as possible.

On the 23rd, at the ‘OLED Settlement Seminar for the first half of 2022’ held at COEX in Samsung-dong, Seoul, UBI Research CEO Choong-Hoon Yi made a presentation on ‘Forecast of the small OLED market, which China is chasing fiercely’.

CEO Yi announced, “Currently, the media reports that the technological gap between Korea and China has almost narrowed, but making and displaying products and mass-producing products are two different things, and the technological gap between Korea and China is still significant.” He continued, “Samsung Display is planning various products such as slideable and Z-folding based on technological competitiveness. However, it will be difficult to commercialize it immediately because the slideable phone invades the existing foldable phone market.”

CEO Yi said, “It is very important not only to develop technological competitiveness, but also to increase price competitiveness. The reason Korean companies closed the LCD business is not because of the good technology of Chinese companies, but because they were pushed back in price competitiveness.”, and “As the technology advances, the performance difference felt by ordinary consumers becomes insignificant, so products with good price competitiveness are inevitable in the market,” he analyzed.

Finally, “China’s OLED industry is growing under the enormous support from the government. In order not to lose the lead in the OLED market like LCD to China, it is essential for domestic companies to prepare for price competitiveness and the government’s support policy,” he concluded.

GrapheneLab, a graphene commercialization technology company, announced that it is possible to manufacture FMMs over 800ppi using graphene.

At the ‘UBI Research First Half 2022 OLED Settlement Seminar’ held at COEX in Samseong-dong, Seoul on the 23rd, GrapheneLab CEO Yong-duk Kwon said, “In the early 2000s, FMM technology, which started in the early 2000s, was not interested in the plating method. It is changing,”, and “After 2013, many patents related to the plating method FMM manufacturing technology have been applied, and it is easier to apply the plating method than the currently used etching method in order to go to high resolution.”

Next, CEO Kwon said, “We moved away from the existing limiting etching method FMM and applied the plating method FMM. Compared to the etching method, where 400ppi was the limit at the same thickness, the plating method realized more than 600ppi.”, “Etched metal mask has a dead zone of 8um in length due to the INVAR structure that becomes sharp like a dot when etching at a depth of 20um, whereas there is no dead zone during pattern plating of the plated metal mask.”

Lastly, CEO Kwon said, “For the MSAP electroforming technology, a low coefficient of thermal expansion with a thin thickness is required. As a result of measuring the coefficient of thermal expansion using TMA on the plated sample, it was measured up to 3.1ppm, and it went down to 2.5ppm without heat treatment.”

<iPhone13/Apple>

It seems that BOE has started line operations for iPhone 13.
Back in March, most of the iPhone 13 shipments were canceled due to an issue with Apple. BOE will now resume production. With this new development, BOE’s forecast for iPhone 13 production this year is expected to increase after being adjusted down in March.
BOE has a total of 20 iPhone module lines at its B11 (Mianyang) plant. BOE’s production of the iPhone 13 is believed to have begun in early June and production of the iPhone 14 is expected to begin as well. The B11 factory has iPhone 13 line to produce iPhone 12 and 13 and iPhone 14 module line exclusively for iPhone 14, as the process is quite different from iPhone 13 line.
Details of BOE’s iPhone 13 and 14 production volume, panel unit price, and module line by product can be found in UBI Research’s ‘China Trend Report’. UBI Research’s ‘China Trend Report’ can be inquired on the UBI Research website.

1Q of 2022 OLED Emitting Material Market $420 million, up 9% Compared to the Same Quarter of the Previous Year

/in , /by

According to “2Q22 OLED Emitting Material Market Track”, a quarterly report published by UBI Research, the sales of emitting materials in the first quarter were $421 million, down 21.1% (QoQ) from $533 million in the previous quarter but was an increase by 9% (YoY)when compared to $386 million in the first quarter of 2021.
Although sales of emitting materials for TV and mobile devices decreased compared to the previous quarter, IT sales recorded a meaningful figure of $6.6 million. Although sales fluctuate depending on seasonal demand for applied products, if the sales of emitting materials are analyzed by application product, TV use is gradually increasing.

The top 3 companies in 1Q sales were UDC($86.6 million), DuPont($41.3 million), and Duksan($37.5 million). Duksan became the number one company in sales as a Korean company. The overall sales of luminescent materials in the first quarter decreased compared to the previous quarter but only UDC’s sales increased. Sales decreased to $421.5 million in 1Q22 from $533.8 million in 4Q21. However, UDC’s 1Q22 sales increased to $86.6 million from 4Q21’s sales of $85.5 million. It is estimated that this is due to the rise in the price of rare earth metals, a key material for manufacturing dopant.
Estimated sales of emitting materials in 2022 are $1.77 billion and are expected to grow to $2.4 billion in 2026.
By application product, the projected sales of emitting materials for smartphones this year are $1.4 billion, accounting for 79% of the total.
Of the projected sales in 2026, emitting materials for TV are expected to reach $550 million, which is expected to increase by 23%. In addition, emitting materials for IT are expected to account for 9% of $210 million.

“OLED Emitting Material Market Track” surveys and analyzes the market for quarterly OLED emitting materials. The total market of light emitting materials was identified by examining sales by light emitting layer and common layer. Performance analysis was categorized by country, panel maker, application product, layer, and OLED method (RGB, WRGB, QD-OLED). In addition, OLED market information for the next five years (up to 2026) was forecasted by predicting the amount of emitting material usage and sales by company. The quarterly market track provides necessary information to industry professionals who lead the OLED industry.

Chinese Panel Makers in Crisis! Will the Display Business’s Deficit Increase This Year?

/in , /by

Honor 70 With Panels Supplied by Visionox

Chinese panel makers such as Visionox and BOE are expected to face losses due to cost pressures.
The operation rate of Visionox was analyzed to be high. This is because Visionox is exclusively producing 70-80% of Honor, a large Chinese smartphone manufacturer.
However, despite the high operation rate, Visionox’s business status is precarious at best. Through cooperative efforts, Visionox was allocated most of Honor’s panel production quantity, but it is known that Honor has requested additional panel price reduction. According to some sources, Visionox is currently facing a loss of about 200 million yuan per month due to the reduced panel price.
BOE, the largest panel maker in China is also facing trouble. BOE along with Visionox had previously been in charge of panel production for Honor but received almost no allocation of production volume from Honor. Earlier this year, BOE faced tremendous difficulty due to the cancellation of existing iPhone 13 shipments to Apple. In April, BOE’s CEO Gao Wenbao felt a sense of crisis due to pressure on OLED and LCD volume and price and gave direct orders on cost reduction. Currently, BOE’s OLED line operation rate is less than 40% and it is estimated that the OLED business unit may incur a loss of about 10 billion yuan this year.
LCD, which is one of the main businesses of Chinese panel makers, is continuously falling in prices and the supply and demand of panels from smartphone set makers are sluggish. If an appropriate countermeasure is not found, Chinese panel makers will continue to experience a growing deficit in the display business.

The higher the refresh rate, the smoother the movements on a screen without afterimages. As displays featuring higher refresh rates present better image transitions, they are the tools of choice among first-person shooter (FPS) players who need to perceive fast-changing game situations as quickly as possible.
“OLED with high refresh rate is the perfect combination for a premium gaming experience, with super-low response time, super-wide color gamut, and super-high contrast ratio. In addition, it balances well between high resolution and high refresh rate performance,” said Clark Peng, Vice President of MSI Notebook Product Management Division. “Therefore, the latest 240Hz OLED display is suitable for high-performance enthusiasts and content creators as well as for gamers enjoying premium games,” he added.
“Our new 240Hz refresh rate OLED meets and exceeds the demand of consumers who have long been waiting for a laptop with a high refresh rate OLED panel,” said Jeeho Baek, Executive Vice President and Head of Samsung Display Strategic Marketing for Small and Medium Business. “The clear advantages offered by high refresh rate OLED panels compared to LCDs will be a game changer for the gaming industry.”
To introduce Raider GE67 HX to the world, MSI will hold a new product launching event on its YouTube channel on June 7, 2022, 10:00 a.m. PDT under the theme “MSIology: Ahead of the Curve.”

 

What is the future change of WRGB OLED to respond to QD-OLED?

/in , /by

2As Samsung Display’s QD-OLED begins to be applied to TVs and monitors in earnest in 2022, technological changes are being detected for LG Display’s WRGB OLED, which has been leading the large OLED market.

LG Display’s WRGB OLED has produced a WBC structure consisting of two blue layers and one red+yellow green layer in Paju by the end of 2021, and a WBE structure consisting of two blue layers and one red+green+yellow green layer in Guangzhou. Deuterium substitution technology was applied to the blue of the WBE structure.

Since 2022, LG Display has stopped producing WBC panels from its Paju line and has been producing ‘OLED.EX’ panels with deuterium substitution technology applied additionally to green of WBE produced in Guangzhou.

<Photo of OLED.EX presented by LG Display at the 2022 OLED Korea Conference>

At SID 2022, LG Display also exhibited a large OLED panel with micro lens array technology. Micro lens array technology was applied to Samsung Electronics’ ‘Galaxy S Ultra’ series, and it is the first technology applied to large OLEDs. LG Display is known to expect a 20% improvement in luminance compared to the previous one by applying micro lens array technology. Panels which micro lens array technology is applied are expected to be produced in Paju from the second half of this year.

Lastly, it is known that LG Display is developing a structure in which yellow green is removed from WRGB OLED. By eliminating yellow green, material and processing costs can be saved, and color gamut is expected to be improved.

Attention is paid to how LG Display’s WRGB OLED will evolve to compete against QD-OLED.

[UBI Research China Trend Report] Will BOE Provide UPC Panel with Transparent PI Substrate to Oppo?

/in , /by

BOE, the largest display maker in China, produces UPC (Under Panel Camera) panels with transparent PI substrates.

UPC is a technology that makes a full screen of a smartphone possible by placing the front camera under the screen. The UPC technology that is currently commercialized is a method of patterning the cathode electrode and changing the resolution near the camera. However, this time it is expected that a transparent PI substrate will be additionally applied to the UPC panel supplied by BOE to Oppo.

Existing transparent PI substrates had difficulties in mass production due to the high process temperature of LTPS TFT. Yet, the recent test results of the panels with the transparent PI substrate produced by BOE reached most conditions of satisfactory levels even at the LTPS TFT process temperature.

The UPC OLED panel with the transparent PI substrate developed by BOE is expected to be installed in Oppo’s upcoming products.

Samsung Display, LG Display, and BOE are expected to supply panels to Apple’s new iPhone 14 series in 2022. It is expected that Samsung Display will supply panels to all models in addition to iPhone 13 series. LG Display will supply 6.12-inch LTPS models and 6.69-inch LTPO models. BOE will supply panels only to 6.12-inch LTPS models.

The existing 5.4-inch mini model has been removed from the iPhone 14 series and a 6.69-inch Max model has been added. The size and resolution of iPhone 14 Max are the same as iPhone 14 Pro Max and LTPS TFT is applied instead of LTPO TFT.

In terms of design, the iPhone14 Pro and 14 Pro Max will have a punch hole design instead of the conventional notch. Apple’s punch hole design is expected to be applied as a double punch hole design due to various sensors and cameras.

Meanwhile, the total OLED panel supply to Apple in 2022 is expected to be about 215 million units, with Samsung Display expected to supply 135 million units, LG Display 55 million units, and BOE 25 million units. However, shipments are expected to be organically controlled due to market conditions and Apple’s policies.

[2022 OLED KOREA CONFERENCE] LG Display’s OLED 3.0 Captures Brightness and Lifespan Simultaneously

/in , /by

 

At the keynote session of UBI Research’s ‘2022 OLED Korea Conference’ held from April 6th to 8th, Sang-Hyun Ahn, Managing Director of LG Display, announced, ‘The Present and Future of Automotive OLED Display: LG Display’s Future Outlook’.

Director Ahn announced, “The future will transform people and vehicles, and vehicles and vehicles to be connected, autonomous, shareable, and electrically driven. In order to respond to these changes, vehicle displays are getting bigger and more diverse in design, and displays are being applied to various locations to provide sights and information”.

Director Ahn continued, “The automotive display industry was led by LCD, but the OLED market is also gradually expanding its area.” He predicted, “The automotive OLED market will be worth $1.2 billion in 2025, It is also possible to grow to $6 billion.”

In addition, Director Ahn said, “LG ​​Display has already introduced an OLED 1.0 structure that satisfies the minimum requirements for automotive display: brightness of 800 nits and lifespan of 10,000 hours. Unlike OLED for smartphones, OLED for automobiles requires brightness of 800 nits or more to grasp accurate information even during the day, and lifespan of 10,000 hours or more is essential because the use cycle is more than 10 years. Although there is a trade-off between brightness and lifetime, we plan to develop OLED 3.0 with a brightness of 1,000 nits or more and a lifetime of 10,000 hours or more by overcoming this through development of materials and structures.”

Lastly, Director Ahn mentioned about future displays such as extra-large and transparent, slidable, and rollable that are applied to vehicles and said, “Many companies want large and many screens, but they want to hide those screens inside the vehicle. Slidable panels, which can be a solution to this, are already technologically stable and can become common around 2025. On the other hand, rollable panels, such as those that come down from a vehicle sunroof, still have a long way to go, but we will continue to develop them.”

[2022 OLED KOREA CONFERENCE] Samsung Electronics Joins the OLED TV Market, and the TV Panel Market is Expected to Exceed 20 million Units in 2025

/in , /by

At UBI Research’s ‘2022 OLED Korea Conference’ held on April 6th-8th, UBI Research CEO Choong-Hoon Lee gave a presentation on, ‘OLED Market Review’.

CEO Lee presented the status of the entire OLED industry, market, and outlook with a focus on issues in 2022.

CEO Lee first announced the OLED TV business, a major issue in the recent OLED industry. CEO Lee said, “The biggest issue that has been heating up the OLED industry since the end of last year is OLED TV. There are topics such as Samsung Display’s re-entry into the large OLED business, sales of QD-OLED TVs between Samsung Electronics and Sony, and visualization of collaboration between Samsung Electronics and LG Display.”

In the TV OLED panel demand and supply forecast, CEO Lee said, “If Samsung Electronics purchases OLED panels from LG Display and conducts OLED TV business, LG Display and Samsung Display can supply a total of 12 million TV OLED panels this year. Among them, demand is 11.7 million units, and oversupply accounts for only 3%.” In addition, “With the joining of Samsung Electronics, the demand for OLED TV panels is expected to expand to 13 million units in 2023 and 20 million units in 2025. According to the expanding market, companies need to expand their facilities by the third quarter of this year” he predicted.

CEO Lee continued, “LG ​​Display has been working hard to secure funds for 8.5 generation OLED line expansion since last year, and it is estimated that it will secure additional funds for 45K expansion within this year. With LG Display’s additional measures, the TV OLED panel market is expected to reach 13.5 million units in 2023 and 16 million units after 2024. However, to secure a market of more than 20 million units, it is necessary to plan to invest in the 10.5 generation by next year” he analyzed. He also said, “If Samsung Display invests, 10.5G investment is desirable, but 8.5G investment is expected.” He said, “Whether LG Display invests or Samsung Display invests, a long-term supply contract with Samsung Electronics for 10.5G investment should take precedence. If the investment proceeds, Samsung Display is expected to secure its own funds, but LG Display is expected to require joint investment with Samsung Electronics.”

‘2022 OLED Korea Conference’ was a conference for exchange of ideas, business relationships, and partnerships with renowned speakers from major companies in the display industry from all over the world. ‘2022 OLED Korea Conference’ held a business conference on the 7th and 8th, beginning with a tutorial on April 6th.

 

 

 

[2022 OLED KOREA CONFERENCE] What New Technology Will Advance OLED for Mobile Devices?

/in , /by

At UBI Research’s ‘2022 OLED Korea Conference Tutorial’ held on April 6th-8th, Dr. Jae-Jin Yoo from the Department of Electrical and Computer Engineering at Seoul National University gave a presentation on, ‘An Overview of OLED Materials and Devices’.

Dr. Yoo explained the paradigm and market prospect of OLED for mobile devices, the structure of each layer, and the light emitting material. Although LCD is still leading the market by introducing mini-LED and other technologies, it is predicted that OLED will lead the display market in the future.

Dr. Yoo explained that among the latest technologies, “LTPO TFT is a technology newly applied to mobile by supplementing the shortcomings of LTPS TFT and oxide TFT process. LTPO TFT is a double-designed display with low electron mobility but no leakage current by changing at least one transistor to oxide in the LTPS TFT process”. He also explained, “In still images, LTPS TFT needs to be driven at 60Hz to maintain the brightness of the screen due to high leakage current, but for oxide TFTs, 1Hz operation is possible because of low leakage current.” Dr. Yoo added, “Although there is an issue that the process of LTPO TFT is more complicated than that of LTPS TFT, it can reduce the total power of mobile devices by 10~15% and it has the advantage that it can be applied to AOD (Always on Display).”

Next, introducing the OLED deposition method and vapor deposition machine, he explained that if the 8.5 generation vertical deposition method, which is currently an issue for IT, is commercialized, it has many advantages in terms of productivity and is a much anticipated technology.

‘2022 OLED Korea Conference’ was a conference for exchange of ideas, business relationships, and partnerships with renowned speakers from major companies in the display industry from all over the world. ‘2022 OLED Korea Conference’ held a business conference on the 7th and 8th, beginning with a tutorial on April 6th.

Next, regarding the older iPhone models, he analyzed that “iPhone13 series is expected to continue sales for the time being except for iPhone13 Mini. Among iPhone12 series, only iPhone12 will continue to be sold”. He also announced, “Samsung Display supplies panels for all models of the iPhone series, LG Display supplied LTPO models for the first time, and BOE’s panels will continue to be used in iPhone12.” In addition, he predicted, “Suggestions to apply not only LCD but also OLED to iPhone SE3 would continue and iPhone 11’s camera is expected to be used. Face ID would not be applied.”

Regarding the timing of OLED application for iPad and MacBook, Nakane said, “It is expected that two models of iPad air with OLED will come out in the second half of 2024 at the earliest and OLED will be applied to MacBook Air in the second half of 2025 at the earliest.” Finally, “the business plan for the foldable model has not been decided, but it seems that they are interested in a PC-size foldable model rather than a smartphone-sized foldable model. The plan is to release them after 2026.” he predicted.

 

[China Trend Report] TCL CSOT’s T8 Project to Invest in Generation 8.5 Inkjet Printing Technology

/in , /by

According to the ‘China Trend Report’ published by UBI Research, TCL CSOT plans to apply the generation 8.5 inkjet printing OLED technology to the T8 line. It is expected that some layers will be formed by vapor deposition in the inkjet printing method rather than the complete inkjet printing method. The location is likely to be Guangzhou.

TCL CSOT’s T8 line was scheduled to start construction in March 2022 using the inkjet method, but there were rumors that the schedule continued to be delayed due to investment scale and yield issues. There are also talks about the project being canceled altogether. However, it seems that TCL CSOT has continuously improved its technology by continuously collaborating with JOLED.

LG Display’s automotive OLED panel recognized for ‘best picture quality’ for passengers

 

  • Obtained international certification for ‘High Visibility Vehicle OLED’ from German TUV, a global certification body
  • Provides a wide viewing angle while consistently maintaining high image quality in a wide range of driving environments and low temperatures of -40 degrees Celsius

Applying new OLED technology that stacks light emitting devices in multiple layers, improving screen brightness and lifespan

LG Display (CEO and President Ho-Young Jung)’s automotive OLED panel was recognized for its best picture quality in the global market.

 

LG Display announced on the 26th that it had obtained the ‘High Visibility Automotive OLED (OLED)’ certification from Germany’s ‘TUV Rheinland’, a global certification body.

 

LG Display’s automotive OLED panel consistently realizes the best picture quality in a wide range of driving environments, including the brightness (10 to 5,000 lux) that the driver encounters during the day and at night, and maintains the same picture quality even at a harsh low temperature of minus 40 degrees Celsius. In addition, it was evaluated that it accurately expresses even small contents that are only 5% of the full screen size without distortion at any viewing angle between the driver’s seat and the front passenger’s seat.

 

This product applies a new OLED technology(tandem) that stacks R(red), G(green), and B(blue) light emitting devices in multiple layers to significantly improve screen brightness and lifespan compared to products with only one light emitting device. Existing LCDs for vehicles have limitations in that light leak around small content, lowering the contrast ratio, and slowing the response time in a low-temperature environment, leaving an afterimage. On the other hand, LG Display’s self-luminous vehicle OLED has a contrast ratio of 600,000 to 1, which greatly exceeds the certification standard (50,000 to 1) and maintains more than 99% of luminance and color despite rapid changes in the external environment of the vehicle. Also, the response speed is 0.66ms faster than the authentication standard (3ms, milliseconds), so there is no afterimage.

 

Sohn Ki-hwan, managing director of LG Display Auto Marketing/Product Planning, said “This certification proves that tandem OLED for automobiles is the only display that satisfies the highest picture quality and extreme lifespan”. So “We will provide our customers with a differentiated customer experience with a display that is safer to use while driving and more convenient when stopped” he said.

As autonomous driving technology advances, the adoption rate of OLED will increase

/in , /by

At UBI Research’s ‘OLED Settlement Seminar in the second half of 2021’ held on the 19th, Park Seon-hong, head of the Korea Automobile Research Institute, gave a presentation on ‘the status and outlook of future automotive display development’.

Responsible Park said, “If the autonomous driving technology is advanced, the number or time of driving will decrease, and the change of the interior space is essential because the driver pays attention to the interior environment of the vehicle. Through the change of the vehicle display, the change of the steering wheel to secure space, and the change of the seat, the efficiency of the space that can utilize the interior space can be increased.”

Among the changes resulting from the development of autonomous driving technology, Responsible Park said, “With the change of the display inside and outside the vehicle, the degree of freedom of space within the vehicle can be improved as buttons, switches, and gear knobs inside the vehicle are applied to the display.” In keeping with, the display mounted on the vehicle is also changing to a large-screen, large-area curved display.”

Responsible Park said, “Displays that secure the reliability of autonomous driving by communicating with the outside such as pedestrians and two-wheeled vehicles through external communication as well as the inside of the vehicle are gaining prominence. By displaying information about the vehicle’s condition (acceleration or deceleration, whether it is stopped, etc.), safety issues can be controlled.”

Currently, automotive displays have a high adoption rate of LCD, but OLED can realize flexible displays, and its thin thickness, high contrast ratio, fast response speed, and wide viewing angles make it possible to apply it in complex and diverse spaces inside automobiles in line with the era of autonomous driving. expected to increase. LG Display is already mass-producing POLED for automobiles, and Samsung Display and Chinese panel makers are also preparing for mass-production of OLED for automobiles.

As autonomous driving technology develops, automobiles are emerging as a new concept of ‘rest and comfort’ out of a means of transportation. While the evolution of in-vehicle displays is essential in such a leisure space, expectations are being raised on how much influence OLED will have on the market as a display for automobiles in the future.

At UBI Research’s ‘2021 OLED settlement seminar for the second half of the year’ held on the 19th, UBI Research CEO Choong-Hoon Yi gave a presentation on the settlement of small/mid-large OLED industry and future market prospects.

CEO Yi said, “The total sales of OLED for mobile devices in the third quarter was $10.3 billion, up 23.6% from the second quarter and 64.1% from the same period last year. OLED for phones grew to a meaningful number for the first time to $540 million in the third quarter.”

According to the announcement by CEO Yi, the total shipment of smartphones and foldable phones in the third quarter was 167 million, up 22.7% from the previous quarter and 55.3% from the same period of the previous year. “The smartphone market contracted in 2020 due to the spread of Corona 19 and sanctions by Huawei, but the market is growing out of this situation in 2021 thanks to the popularity of Apple’s iPhone 12,” said CEO Yi.

Comparing OLED shipments for smartphones in the third quarter by panel maker, Samsung Display took 72.9%, followed by BOE and LG Display with 9.4% and 5.8%, respectively. CEO Yi mentioned, “Samsung Display maintained 80% level just a year ago, but BOE is gradually gaining strength as BOE’s production lines are being prepared step by step.” and “In terms of sales, Samsung Display accounted for 79.0%, which is higher than the shipment share, and BOE, 8.8%, which is lower than the shipment share. This result appears because the panels of Samsung Display and LG Display are sold to Apple at the highest price.”

Next, CEO Yi predicted, “In terms of OLED shipments by country, Korea dominates the market with 78.7%, but the Chinese market, which currently accounts for 21.3%, will gradually grow and the shipments of the two countries will become similar in about five years.” He also predicted, “In order for the industry to grow, the top-level set makers in the supply chain are important, and based on China’s numerous set makers and the large domestic market, it is highly likely that the leadership will be transferred to China in about five years.”

In the smartphone market forecast analysis, CEO Yi said, “In 2021, OLED shipments for smartphones and foldable phones are expected to reach 580 million units, and the market will grow by 100 million units in the next two years, reaching 600 million units in 2023 and 700 million units in 2025. We will overcome it,” he predicted.

6.1 LTPS(60Hz) SDC, LGD, BOE(expected)
6.1 LTPO(120Hz) SDC
6.7 LTPO(120Hz) SDC

 

As for the panels that BOE supplied to the iPhone 12, EVEN process was carried out on the B7 (Chengdu) line, and the module process was carried out on the B11 (Myeonyang) line. The process was carried out separately due to the yield issue of the B7 module line, but from the iPhone 13, the deposition yield of the B11 line has improved and both the EVEN process and the module process are carried out on the B11 line. The total amount of panels that BOE will supply for iPhone 13 is estimated to be 15 million units, and although BOE has a target of producing more than 5 million units within this year, it is expected to be in the range of 2 to 3 million units in reality.

Meanwhile, it is known that BOE is also rapidly developing the LTPO line. The LTPO development speed of BOE’s B11 line is faster than that of the B7 line, and it is known that it already has mass production. At BOE, LTPO development is at a significant level, and attention is being paid to whether it will be able to supply LTPO panels to Apple’s next iPhone 14 (working title).

BOE has recently expanded its supply of flexible OLEDs to Samsung Electronics as well as Apple, and its influence in the flexible OLED market is growing. As BOE supplies new panels to Apple for the first time, attention is focused on how domestic panel makers will respond.

Samsung Display begins mass production of QD-OLED in the fourth quarter of 2021, a new growth opportunity in the large OLED market

Samsung Display is planning to start mass production of QD-OLED in earnest from the fourth quarter of 2021. The mass production scale is 8.5G 30K/month, and it is expected to be mass-produced mainly for 65-inch 4K resolution panels. Since three 65-inch panels can be produced in the 8.5th generation, about 1 million panels are expected to be mass-produced annually.

At the closing seminar held in the second half of 2020, UBI Research predicted that Samsung Display’s QD-OLED will produce 200,000 units in 2021, 600,000 units in 2022, and 800,000 units in 2025. However, as Samsung Display announced in its second quarter conference call that it will also introduce a monitor product with a smaller QD display than a TV, production is expected to vary depending on the proportion of products..

If mass production begins in the fourth quarter, QD-OLED TV will be unveiled for the first time at the CES 2022 exhibition held in Las Vegas in 2022, and the product is expected to be officially released in the first half of the year.

Joo-seon Choi, president of Samsung Display, emphasized in a recently published sustainability report that “If QD displays are commercialized, new growth opportunities will be created in the large display industry, which has been stagnant for a long time.”

Attention is paid to how much influence Samsung Display’s QD-OLED mass production will have in the large OLED market led by LG Display.

QNED (quantum dot nano-rod LED) structure and core technology

/in , /by

Samsung Display research center is accelerating the development of QNED as the next-generation display following OLED.

The reason Samsung Display is developing QNED as part of its large-size display business is that it is the only display that can produce the image quality that Samsung Display’s biggest customer, Samsung Electronics, can satisfy.

Samsung Electronics’ TV business direction, which has the world’s No. 1 TV market share, is to use QD to make color gamut better than OLED, and to use a display that can maximize HDR performance with high luminance and excellent gradation characteristics on a bright screen.

The only display that can satisfy the needs of Samsung Electronics is QNED.

Items QNED OLED Mini-LED LCD
Color gamut best better best
HDR best better better
Luminance best better better
Contrast ratio best best better
Motion blur best best good

 

QNED is a self-luminous display and because it uses QD, it has the best color gamut, HDR, luminance, contrast ratio, and motion blur, etc., and is a product expected by Samsung Electronics.

It can be confirmed by the structure that QNED is the display with the best characteristics. QNED consists of a pixel layer with a nano-rod LED on the TFT structure of 3T1C used in large OLEDs, and a color conversion layer consisting of QD and CF (color filter) on top.

In OLED, electrodes (cathode and anode) and electrode line for transmitting a signal to a pixel are located above and below the light emitting material, whereas in QNED, both the signal transmitting electrode (pixel electrode) and electrode line are located on the same plane. In addition to the pixel electrode, the QNED additionally includes a reflective electrode to increase light output efficiency. The pixel electrode serves as an alignment electrode for aligning the nano-rod LED.

< QNED section structure >

< QNED pixel structure >

< QNED pixel planar structure >

Looking at the planar structure of a QNED pixel, a plurality of pixel electrodes are connected in series in one pixel, and a nano-rod LED is positioned between the pixel electrodes. The pixel electrode is on the pixel wall (PW) formed of an insulating material, and each pixel is surrounded by a bank (BNK) to separate regions.

 

The core technology of QNED is driving technology and sensing technology.

The driving technology includes a driving technique for aligning nano-rod LEDs and a driving technique for uniformly controlling pixels that may have a deviation in the number of nano-rod LEDs. The alignment circuit includes switching elements for each pixel, and the switching element applies an alignment signal to the pixel. The alignment state of the nano-rod LED is determined depending on which alignment signal is given to each pixel.

< Drive circuit for alignment >

< Sensing transistor for checking alignment >

The most important driving technology is a technology that supplies current to each pixel so that the luminance can be uniform across the entire screen even if the number of nano-rod LEDs per pixel is different. It is a method of controlling each pixel based on the data read from the sensing transistor.

[QNED Technology Completion Analysis Report] details the sensing transistor, sensing wiring, and sensing signals that can check the nano-rod LED alignment status on the panel.

 

As sensing technology, there are sensing technology (sensing transistor) designed inside QNED and sensing technology used in QNED manufacturing. The sensing technology used to manufacture QNEDs is inherent in inkjet systems. There are three sensing technologies in the inkjet system: the number of nano-rod LEDs in the ink and the viscosity analysis of the solvent, the analysis of the number of nano-rod LEDs sprayed on the panel, and the analysis of the nano-rod LED alignment state.

< Inkjet system configuration >

 

QNED has already proven that 4K 65 inches can be driven two years ago. Samsung Display is concentrating on finishing work to secure the screen uniformity of QNED.

Samsung Electronics widens the technology gap by applying new technology to ‘Galaxy Z Fold3’.

/in , /by

According to the ‘2021 OLED Components and Materials Report’ recently published by UBI Research, the ‘Galaxy Z Fold3’, which is expected to be released by Samsung Electronics in August, has UPC (under panel camera) and pol-less (or color filter on) encapsulation, COE) and S Pen technology are expected to be newly applied.

First, UPC, a technology that realizes the full screen of a smartphone by placing the front camera under the screen, has been mentioned using a transparent PI substrate and various technologies such as laser patterning, but in the end, the cathode electrode is patterned with a laser and the resolution near the camera is different. Thus, it seems that the maximum transmittance was secured. It is analyzed that the transparent PI substrate was not applied to the mass production process due to the high process temperature of the TFT.

Although many panel makers have developed pol-less technology, which replaces polarizers with color filters and low-reflection technologies, they could not be applied because they did not show as much anti-reflection effect as polarizers. The polarizing plate is effective in preventing external light reflection, but reduces the amount of light emitted from the OLED light emitting layer by more than 50%. If the polarizer is removed, more light can be emitted with the same power to the outside, so if the same luminance is implemented, battery consumption can be reduced. Samsung Display seems to have implemented pol-less technology by applying color filters, low-reflection films, and black pixel define layer (PDL).

The S Pen is finally applied with an electro-magnetic resonance (EMR) method, and the 30 um thick product used in the previous work is expected to be used as it is for the UTG. The AES method, which does not require a digitizer, was also considered due to the flexibility issue of the digitizer made of metal, but it is expected that the S Pen will eventually be applied in such a way that the digitizer is located on both sides of the panel.

The ‘2021 OLED Components and Materials Report’ published this time includes not only the development trend of foldable OLED, but also the development trend of mobile devices and materials for TV. It is expected to be of great help to related companies.

97.5% of 6-inch OLED smartphones released in the first half of 2021,

/in , /by

Of the 122 OLED smartphones released in the first half of 2021, 119 6-inch smartphones were released, occupying an overwhelming share of 97.5%. Compared to the 6-inch smartphones released in 2018, which accounted for 78% of the total, it has become the mainstream of the smartphone market in just three years. One 5-inch model and two 8-inch models were released, and the 7-inch model was not released. The 5-inch model is Asus’ Zenfone8, the 8-inch model is Xiaomi’s Mi Mix Fold, and Huawei’s Mate X2.

By display design, hole model was released the most with 103, followed by notch model with 13 and narrow bezel model with 6. As in 2020, products with a home button were not released.

Looking at the distribution by resolution, 400~500ppi products were released the most with 64, accounting for 52.5% of the market share, 48 products with less than 400ppi and 10 products with more than 500ppi. The highest resolution product was Sony’s Xperia 1 II, which recorded 643 ppi.

In the display area (D.A), which is the ratio of the display to the size of the smartphone, products belonging to 80-90% accounted for 84.4%, 13.9% of those over 90% and less than 80% were not released. This is analyzed as a result of the disappearance of the home button and the continuous release of full-screen smartphones. The product with the highest D.A was 94.1%, which was occupied by Huawei’s Mate 40 Pro 4G, followed by Huawei’s Nova 8 pro in second place and Honor’s View40 in third place.

Finally, by country, China released the most with 104, followed by Korea with 12, Taiwan with 4, and Japan and Germany with 1 each.

How far has QNED completed?

/in , , /by

The reality of QNED (quantum dot nano-rod LED), which Samsung Display is preparing as a next-generation display, has become clear.

As a result of analyzing 160 patents applied by Samsung Display, it was confirmed that the structure constituting the QNED has already been completed, and that the only remaining task is to keep the number of nano-rod LEDs arranged in the light-emitting pixel constant.

As a result of classifying the contents of each patent according to the purpose of the application, a total of 39 types were found, with 49 cases related to device arrangement being the most. The following is 20 cases to improve the light efficiency.


The number of aligned nano-rod LEDs per pixel, which determines the yield and image quality characteristics of QNED, is determined by the distribution of LEDs in the ink, the number of LEDs injected into the pixel, and the alignment ratio of the injected LEDs.

If the distribution of the number of nano-rod LEDs per pixel is different, there is a change in the voltage applied to each pixel, resulting in a defect.

It has been confirmed that Samsung Display has already developed a method for making the number of nano-rod LEDs per pixel constant and an algorithm that can make the luminance uniform even when the number of nano-rod LEDs is different.

In the “QNED Technology Completeness Analysis” published this time, it was written as the contents of the previous report published through analysis of 94 patents and 66 newly added patents. It was analyzed and recorded.

In this report, QNED patent numbers, classification tables, and quantitative analysis data that have not been disclosed before are provided in Excel.

UBI Research has published a market track on the market performance of 10-inch and larger OLEDs. Applications include TVs, monitors, notebooks, and tablet PCs.

According to UBI Research’s medium and large OLED market track, the total sales in the first quarter was $1.46 billion, an increase of 16.9% compared to the previous quarter (QoQ) and 156.3% compared to the same quarter of the previous year (YoY).


The reason for the sales increase in the first quarter is due to the increase in sales of large OLED panels for TVs and OLEDs for notebooks. TV OLED panels sold 1.6 million units in the first quarter, achieving the best performance ever. Notebooks OLED shipments are also increasing rapidly from this year. Notebook.s have a lot of icons and are the most concerned about image sticking, which is considered the biggest drawback of OLED. However, Samsung Display has been promoting since 2020 by developing OLED for notebooks that completely overcomes the shortcomings of OLED as a manufacturing technology accumulated from smartphones. Although OLED sales for notebooks in 2020 were only 800,000 units, shipments of 1.1 million units were achieved in the first quarter of 2021. Samsung Display is gradually expanding its business area to IT products following smartphones.

 

Publication of China OLED industry trend analysis report

Despite the ongoing Corona-19 situation and the US government’s sanctions on Huawei, the adoption of OLED by Chinese smartphone makers is gradually increasing.

The Chinese market, which had been concentrated in the low-end smartphone market, has been expanding into the mid-to-high-end market as Huawei increased its global market share. In particular in the Chinese market, with only the iPhone remaining in the premium smartphone market, Huawei, Oppo, Vivo, and Xiaomi have rapidly increased their market share in the mid- to high-end market with OLED smartphones.

Based on this growth, following Royole and Huawei, Xiaomi also launched a foldable phone in 2021. Chinese display makers have risen to the top spot in LCD production, and their OLED production technology has reached a significant level, and they are also directly producing foldable OLED, which requires the highest level of difficulty in OLED production technology. Foldable OLEDs from BOE and CSOT are used in Huawei and Xiaomi’s foldable phones.

In the “Chinese OLED Trend Report for 2021” published by UBI Research, the OLED-equipped smartphone, TV, and watch industries produced in China were analyzed, and technology development/investment trends and market performance of OLED panel makers were analyzed. In addition, the size of the light emitting material and component material market used by Chinese OLED panel makers was analyzed and summarized.

57 types of OLED smartphones released in the first quarter of 2021 were counted. This number is more than double the number of 27 species in the same quarter last year. This is because Chinese smartphone makers such as Oppo, Vivo, and Xiaomi have mass-released new OLED smartphones to occupy Huawei’s smartphone market.

The OLED market by Chinese panel makers is also growing explosively due to the active use of OLED by Chinese smartphone makers. In the first quarter of 2021, OLED sales for smartphones were counted at 990 million dollars, which increased by 38.3% compared to the same quarter of 2020 (YoY). The reason for the rapid growth of OLED sales is the increase in selling prices as OLEDs produced by Chinese panel makers move from low resolution to high resolution.

The amount of light emitting materials used by Chinese panel makers has not seen a significant increase yet. In the meantime, production was low due to low yield due to low production technology, but now production is increasing even with the same amount of material used. In 2020, 13.8 tons of luminescent material was used.

 

Forecast of OLED Light Emitting Materials Market in 2021: $15.2 billion

/in , /by

Citing the recently published ‘2021 OLED emitting material report’, UBI Research (www.ubiresearch.com), a company specializing in OLED market research, forecasted that the OLED emitting material market size in 2021 will be $1.52 billion, a 17% increase from $1.3 billion in 2020.

By country, Korean panel makers’ material purchase rate is expected to account for 74.3% of the total market, and China is expected to account for 25.7%. By company, Samsung Display is expected to take the 1st place with 45.9% of the total, LG Display to take second place with 28.5%, and BOE to take third place with 13.7%.

By evaporation method, it is expected that the emitting materials for RGB OLED used for small OLEDs account for 81.4% of the total market, and the emitting materials for WRGB OLED of LG Display account for 18.3%. Samsung Display’s QD-OLED emitting material, which will be released in the second half of this year, is expected to account for less than 1% of the total material market as shipments of QD-OLED panels are not expected to be large.

Meanwhile, the ‘2021 OLED Emitting Material Report’ published this time includes not only the OLED emitting material market forecast, but also the development trend of low-power driving technology, the development trend of blue phosphorescent materials, and the material supply chain of Chinese panel makers. It is expected to be helpful for the companies related to emitting materials understand related technologies and forecast future technology directions and markets.

Why did Apple choose LTPO?

/in , /by
  • Utilizing high refresh rate and reducing power consumption by up to 20%
  • but, 30% more complex process

————————————————————————————————————————————————————–

LTPO (Low Temperature Poly-crystalline Oxide) is an Apple’s technology made by combining LTPS (Low Temperature Poly-Silicon) and Oxide (oxide semiconductor, mainly IGZO) TFT technology. It is characterized by further improving power efficiency by using LTPS with fast electron mobility and oxide with less leakage current.

LTPS TFT with fast electron mobility is applied as a driving role, and oxide TFT with low leakage current is applied as a switch.

LTPO was first applied to smart watches before smartphones. The first device to be applied is the Apple Watch Series 4, released in 2018, and was supplied exclusively by LG Display. Samsung Electronics also applied LTPO to the Galaxy Watch Active 2 in 2019.

Apple Watch with LTPO applied                                   Galaxy Watch Active 2

LTPO technology, which is characterized by low power, is suitable for 5G smartphones that consume more power than existing LTE and is in high demand from major smartphone manufacturers. Samsung Display launched the Galaxy Note 20 Ultra, the first smartphone to which LTPO technology was applied.

Galaxy Note 20 Ultra with LTPO applied

It is expected that Samsung Display will dominate the market as it is leading in technology of LTPO OLED panels for Smartphones, and as a latecomer, LG Display is known to develop panels to be applied to the iPhone, which is scheduled to be released next year.

LTPO technology does not only have the advantage of low power. Because masks are added during the process, the unit price is increased due to the complexity of the process. Manufacturing methods are completely different from existing LTPS and Oxide TFT, and processes are more than 30% complicated. Complex manufacturing processes lead to higher unit prices.

From a manufacturer’s perspective, LTPO application effect must be as large as the increased process unit price. Considering this, it is analyzed that the need and effect of LTPO application are greater (because of the always-on display function) than smartphones. Smartwatches also had a greater effect on lowering power consumption than smartphones. If LTPO is applied, the refresh rate can be lowered, which reduces power consumption, because smartphones require a high refresh rate. The refresh rate is a figure that shows how many scenes are shown per second, and the higher the refresh rate, the smoother the screen transition.

In the case of smartphones, if you play games or watch videos, you can quickly switch to the screen with high refresh rates, allowing you to experience smooth and smooth gaming. Recently released flagship Smartphones are currently supporting 120Hz refresh rate. Considering this trend, LTPO technology, which can reduce screen conversion, is not very suitable for smartphone utilization.

However, in a still picture, LTPS requires a driving of 60Hz to maintain the brightness of the screen due to a high leakage current, but the oxide TFT can be driven at 1Hz because of a low leakage current, so there is no decrease in brightness.

 

As a result, the LTPO TFT has the effect of reducing the total power in mobile devices by 10% to 15% compared to the LTPS TFT.

 

To take advantage of LTPO’s technology, new applications and services that consumers want are needed. If it is always turned on and has a function to flow information or a service function to view information by turning on only a certain part of it, OLED and LTPO technologies will be combined and used as an advantage.

  • Samsung Display’s first OLED panel mounted on Hyundai’s first exclusive electric vehicle,’Ionic 5′
  • Optional digital side mirror to mount camera and display screen
  • Significantly helps to improve the mileage and fuel economy of electric vehicles

————————————————————————————————————————————————————–

Samsung Display’s organic light-emitting diode (OLED) display will be used in Hyundai Motor’s first exclusive electric car,’Ionic 5′.

▲ Inside Hyundai’s first exclusive electric car Ionic 5

Ionic 5 can choose a side view camera as an option along with a standard side mirror that uses a regular mirror as before. With this option, there are no mirrors on the side mirrors. In the digital side mirror, a camera is mounted in the place of a general side mirror and a display is located inside. You can see the back and surroundings of the vehicle using the camera and display screen. The wider field of view reduces blind spots and has the advantage of being able to see the surroundings brightly even in the dark underground or at night. This display screen is Samsung Display’s OLED product.

The contract for supplying OLED for vehicles is significant in that it is a 10-year contract between Hyundai Motor Company and Samsung. Samsung Display signed a contract to supply 8-inch LCDs for navigation in 2011, and supplied supplies for three years, but there was no significant business link between the two groups. Hyundai Motor Group selected Samsung Display as the first supplier when it first selected OLED as a vehicle display. As Hyundai Motor adopts Samsung products for its first dedicated electric vehicle with high symbolism, analysts say that the scope of cooperation between Hyundai Motor Group and Samsung will continue to expand in the automotive industry.

Samsung Display has been supplying OLED displays to Audi’s electric vehicle ‘e-tron’ that applied the same system under the name of ‘virtual side mirror’ from 2018.

Audi’s first pure electric car’e-tron 55 quattro’ was applied with ‘virtual side mirrors’ for the first time in mass-produced cars. Are collected.

The e-tron is equipped with a diamond-shaped OLED display, but the digital side mirror of Hyundai Ionic 5 has a square display design. When I got on the inside of the vehicle and looked at the digital side mirror, I could clearly see the outside from the inside through the screen. In addition, the screen response speed was also smoothly driven without interruption. It is a structure that can easily adapt to drivers who were used to the existing mirror-type side

 

 

 

 

Cover window market forecast for foldable phones

/in , , /by

The biggest difference between flexible OLED and foldable OLED will be the cover window material. In terms of price competitiveness, various Colorless Poly Imide (CPI) are superior to suppliers, but in the end, the cover window market is expected to depend on which material Samsung Electronics and Apple choose.

Samsung Display plans to supply only foldable OLEDs using UTG (Ultra Thin Glass) to Samsung Electronics and other China this year, and is expected to adopt UTG as the main cover window material in the future.

BOE and CSOT currently focus on transparent PI, but they are securing technology by continuously collaborating with UTG-related glass processing companies. For this reason, according to the UBI Research component and materials market track, UTG is expected to occupy 80% of the market for foldable cover windows in the future, and transparent PI is low in price and easy to apply to products larger than 10 inches As a result, it is expected to be applied to low-end models, tablets, and notebook models.

 

 

 

 

 

 

In 2020, small OLED shipments increased by 3.4%↑, sales decreased by 2.8%↓

/in , , /by

Corona 19 and Huawei’s US sanctions negatively affected the OLED market for smartphones, but it was a plus with Apple’s strong sales of iphone 12.

Samsung Display completed the Y-OCTA renovation of the Apple line in 2020, and the LTPO TFT secured a 30K scale. By the first half of 2021, the company plans to convert the LTPS line from Apple’s line to the LTPO TFT line.

The foldable phones released by Samsung Electronics in 2020 are the Galaxy Z Flip released in February and the Galaxy Z Fold 2 released in September, both in-folding and using UTG (ultra thin glass). Galaxy Z Fold 2 is a product to which LTPO TFT technology is applied.

BOE failed several times without exceeding the approval process in Apple’s iPhone12 quality test, but received final approval for panel supply at the end of December 2020. BOE’s new line, B12, is an Apple module line that starts bringing in equipment from December 2020, and is aiming for mass production in November 2021.

According to the annual small OLED display report published by UBI Research, small OLED shipments in 2020 increased by 3.4% compared to 2019, but sales decreased by 2.8%. The increase in shipments is due to the increase in OLED for watches, and the decrease in sales is due to the decrease in OLEDs for smartphones.

In 2020, the total sales of OLED for smartphones was 26.7 billion dollars, of which Samsung Display accounted for 78.8% with 21 billion dollars. LG Display has sales of $2.8 billion and a market share of 10.5%. Samsung Display accounted for 91.7% with 2.35 million dollars in 2019. Smartphone sales in 2020 decreased by 6.68 million units compared to 2019.

 

 

Middle and Large OLED sales growth of 40.2% in 2020

/in , , /by

Although Samsung Display’s rigid OLED line is expected to decrease due to a decrease in Huawei’s volume due to the US production, demand for rigid OLEDs is expected to increase as demand for laptops, monitors and tablet PCs is increasing. To respond to this, investment in rigid OLED lines in A4 is also being reviewed. This year’s notebook OLED panel is expected to come out with more than 10 different model product lines, and Apple’s OLED production for iPad is scheduled to start from 2022, so demand for middle and large-sized OLED panels is expected to increase.

In addition, LG Display, a leader in P-OLED supplying in the automotive field, is planning to supply plastic OLEDs for automobiles to German car makers by producing premium OLED panels, and Samsung Display is also supplying OLED panels for vehicles.

According to the 2021 middle and large OLED annual report published by UBI Research, the total sales of middle and large-sized OLEDs in 2020 was $3.882.7 million, and last year was $2.63 billion, an increase of 40.2% from the previous year. By application, the notebook and automobile markets have increased remarkably, and the notebook, monitor, and automotive product markets are expected to grow in 2021.

Samsung Display’s QD-OLED mass production is expected to be around December 2021, and 65-inch panels are highly likely to be used by Sony. Samsung Electronics is expected to receive only 32-inch QD-OLEDs for monitors, not purchasing 65 inches.

LG Display’s 2020 TV OLED panel shipments were counted to 4.4 million units, and if the Guangzhou plant operates at 90K from the third quarter, the production capacity will reach 8.5 million units in 2021.

 

 

2020 OLED annual performance analysis

/in , , /by

Total shipments of AMOLED in 2020 were aggregated to 575.78 million units. This is an increase of 20.41 million units compared to the 557.46 million units shipped in 2019.

The first OLED application products released in 2020 are for automobiles and for notebooks. Analysis by application product shows that the market has increased for foldable OLED, TV WRGB OLED, and watch OLED, and the decline is for smartphone and tablet PC.

Sales in 2020 were $32.68 billion, an increase of $2.3 billion from $32.45 billion in 2019. The insignificant increase in sales compared to the increase in shipments in 2020 is due to the decline in OLED unit prices for smartphones. This is because the OLED unit prices of iPhone and Galaxy S20, which are supporting the OLED market for smartphones, have decreased compared to 2019, and OLED shipments by Chinese panel makers have led to a decrease in OLED unit prices of Samsung Display.

In terms of sales by company, Samsung Display was found to be $22.3 billion, a decrease of $4.2 billion from $26.5 billion in 2019. Samsung Display’s smartphone OLED shipments amounted to 390 million units, a decrease of 40 million units compared to 430 million units in 2019, and sales decreased due to a drop in selling prices. As a result, Samsung Display’s market share in 2020 dropped sharply to 68.2%.

On the other hand, LG Display’s OLED sales reached $68.7 billion, and its market share surged to 21%. LG Display’s sales increase is due to increased shipments of POLEDs for iPhone and OLED panels for TVs.

BOE’s 2020 sales were $1.86 billion, up $7.5 billion compared to 2019. The market share was 5.7%, ranking third.

Korea’s market share in 2019 was 89.3%, falling below 90% for the first time.

Kopin’s 2.6K x 2.6K OLED display incorporated in Panasonic’s new VR glasses

/in , /by

January 19, 2021 – Kopin Corporation announced its Lightning® 2.6K x 2.6K (2560 x 2560 resolution) OLED display on chip (DoCTM) are incorporated in Panasonic’s VR Glasses introduced at the CES 2021 this week.

<Panasonic’s new VR glasses, Source: Panasonic>

The Panasonic VR Glasses are the world’s first high-dynamic-range (HDR) capable, ultra-high-definition VR eyeglasses and offer stunning lifelike images. It comes in a very small form-factor thanks to the 1.3” displays and the slim Pancake® optics. The small, lightweight form factor makes the glasses comfortable to wear for extended periods of time, unlike today’s bulky VR headsets.

The 2.6K x 2.6K OLED DoC is made with Kopin’s patented ColorMaxTM technology for high color fidelity (> 100% sRGB) and a duo-stack OLED structure for high brightness (> 1000 nits). The 10-bit color control, together with the high color fidelity, high brightness and high contrast ratio (> 10,000: 1), enables the much-desired studio-quality, HDR capable VR experience.

“We have worked very closely with Panasonic and Lakeside Optoelectronic Technology on the display and with 3M on the Pancake optics for the Panasonic VR glasses,” said Dr. John C.C. Fan, President and CEO of Kopin.

Wu Di, President of Lakeside Optoelectronic Technology, said, “In the development of 2.6K x 2.6K OLED displays on silicon with Kopin, we optimized the OLED deposition processes, tuned our production line, and delivered the industry-leading products.”

The mini-LED TV market in 2025 is the trend of the premium TV market

/in , /by

Products with more advanced LCDs appear. It is an LCD that has greatly improved brightness, HDR, and color reproducibility by adding QD film and mini-LED to BLU. The existing top-level LCD used a full array local dimming (FALD) BLU with a local dimming zone of about 300 to 500.

When the local dimming zone is increased to more than 3,000 by using mini-LED, the contrast ratio is significantly improved, and the halo effect is reduced compared to FALD BLU LCD TVs. In order to achieve the same performance as OLED, the local dimming zone must have as many pixels as the number of pixels, but due to the limitation of LED size reduction, mini-LED TVs to be sold this year will have a local dimming zone of 1,000-3,000 products.

To make the best LCD TV, a TFT substrate capable of AM driving mini-LED BLU is needed. The competitive pointer of LCD TVs using mini-LED BLU is a technology that can make the image quality similar to OLED while minimizing the local dimming zone and the number of LEDs. In order to realize the same image quality as OLED, the local dimming zone must be more than 100,000 divisions, and hundreds of thousands of LEDs and TFT substrates are required for driving, so the manufacturing cost of panels (including modules) becomes similar to that of OLED.

If the backplane of the mini-LED BLU uses FR4 or BT and the local dimming zone is divided into 3,000, the mini-LED TV manufacturing cost can be reduced to about half of that of the OLED TV, maximizing the quality of the LCD TV while lowering the price. The TV with the best cost performance is created.

The manufacturing cost of mini-LED BLU for 65-inch TVs with a local dimming zone of 10,000 divisions or less is analyzed at 250-1,100 dollars level, and the TV price is expected to range from 1,500 to 6,000 dollars depending on the size and local dimming division level. In 2021, the mini-LED TV market is expected to form 2.5 million units.

In terms of market share with OLED TVs, mini-LED TVs are expected to dominate after 2024.

TCL has led the development of Mini-LED TVs, but the market will be led by Samsung Electronics and LG Electronics.

OLED Market Enters Adjustment Period from Rapid Growth

/in , , /by

As smartphone makers, including Samsung Electronics and Apple, increased the use of OLEDs in flagship models, the growth of the OLED market, which had been rapidly growing, has been braked.

The third quarter of each year is the season with the best OLED performance for smartphones due to the launch of a new iPhone. According to the display market track of UBI Research (www.ubiresearch.com), in the third quarter of this year, 113 million units were shipped, an increase of 26.3 million units compared to 86.7 million units in the last quarter, showing a growth of 30.4%. However, this figure is due to an optical illusion. The reason is that the results in the first and second quarters were very poor compared to before due to COVID-19. Compared to the third quarter of last year, shipments in the third quarter of this year decreased by 17.9%. Shipments are smaller than in the third quarter of 2018.

The decrease in OLED shipments for smartphones in the third quarter is due to the addition of Huawei sanctions to COVID-19. The sharp drop in shipments from Samsung Display and BOE to Huawei deteriorated the third quarter earnings.

There are also many analyzes that companies such as Samsung Electronics, Oppo, and Vivo will benefit from the reflection due to Huawei sanctions. However, since Samsung Electronics is currently struggling in the Chinese market, and the brand power of Oppo and Vivo is less than that of Huawei, it will be difficult to replace the expensive smartphone market in China occupied by Huawei. Therefore, Huawei’s smartphones, which mainly use OLEDs, disappear from the market, and shipments of Samsung Display and BOE are also forced to decrease more than expected.

The growth of the smartphone OLED market is expected to slow for the time being due to Huawei’s smartphone production disruption, which was expected to break through the 300 million units’ market and purchase OLED in large quantities. As a result, the OLED market in China will suffer a severe oversupply situation.

 

Samsung Electronics’ foldable smartphone to be released in 2021, with touch pen and UTG thickness different?

/in , , /by

According to the ‘2020 OLED Components and Materials Report’ recently published by UBI Research, Samsung Electronics’ next-generation foldable smartphones to be released in 2021 are expected to be equipped with a pen function.

It is expected that the pen function will be added to Samsung Electronics’ Galaxy Z Fold2, which was released in September, but the flexibility issue of the digitizer, which is an essential material to support the pen function, and ultra thin glass (UTG), the cover window material. The pen function was not added in the end due to its thin thickness.

In order to add a pen function, Samsung Display seems to be considering applying an active electrostatic solution (AES) method that does not require a digitizer and changing the thickness of UTG.

First, the’Galaxy Note’ series uses an electro-magnetic resonance (EMR) method with a digitizer at the bottom of the OLED panel. The EMR method has good touch sensitivity and does not require a battery to be embedded in the pen, but it is not applicable to foldable devices due to the flexibility issue of the metal digitizer.

Unless the companies developing the EMR method provide a special solution, the AES method is highly likely to be applied to the pen for the next ball double device. In this case, the sensor pitch of Y-OCTA is formed more densely or the Touch IC is more complex. Can be designed.

The AES method is also being developed by LG Display and BOE to apply to foldable devices.

In addition, the thickness of UTG is also expected to change. The 30 um thick UTG, which is currently commercially available, has good flexibility, but due to its film-like characteristics, when pressure is applied with a touch pen, traces remain and may affect touch sensitivity. To solve this problem, Samsung Display is developing UTG with a thickness of more than 60 um in cooperation with glass processing companies.

As the thickness of the UTG decreases as the thickness increases, it is expected that the UTG currently under development will be applied with a concept in which the folded part is processed thin and filled with a material having the same refractive index as glass. In addition, in the future, there is a possibility that an additional coating process will be added after the reinforcement process without a protective film such as PET on UTG.

In UBI Research’s ‘2020 OLED Parts and Materials Report’, Samsung Display’s expected change in foldable OLED was written as a roadmap and the trends of related materials were analyzed. According to the report, Samsung Electronics’ application of pens for foldable devices is expected in 2021, and UTG materials are expected to lead the market at 78% by 2025 in the future cover window market for foldable devices.

 

OLED performance analysis in the first half of 2020

/in , , /by

It was found that COVID-19, which has spread around the world since January this year, has adversely affected the OLED industry as well. According to UBI Research (CEO Choong Hoon Yi)’s [2020 OLED Display Semi-Annual Report], OLED total shipments and sales in the first half of 2020 were 231 million units and 13.2 billion dollars, respectively. Compared to shipments of 230 million units and sales of 13.8 billion dollars in the first half of last year, shipments increased by 1 million units but sales decreased by 600 million dollars.

The reason for the decrease in sales compared to the increase in shipments is because the shipments of OLEDs for watches, which are cheaper, have increased, but OLEDs for smartphones and TVs have decreased. OLED for watch was 22 million units in 1H19, but 1H20 increased significantly to 33.5 million units, helping to increase OLED shipments. However, the OLED market for smartphones decreased by 10.6 million units. The foldable OLED market has risen significantly with the Galaxy Z Flip, which Samsung Electronics released in the first half of this year.

<OLED shipments by major application products>

In the future, the increase in line capacity for mobile devices by panel makers is expected to slow from 2023. Until 2022, investments by Chinese companies are maintained, but further investment is difficult to expect as the oversupply of OLED for smartphones continues.

Samsung Display is converting the LTPS TFT line of the A3 plant to the LTPO TFT line, and since it has been converted so that Y-OCTA can be manufactured at all plants, the mass production capacity is expected to decrease gradually, reaching 9 million square meters in 2021.

As a result, Korea’s mass-produced substrate area is 56.5% until this year, but from 2021, China is expected to have 1% mass-produced capacity, and after 2022, China’s mass-produced capacity will exceed 50%.

Smartphone OLED shipments plummeted to 87 million units in the second quarter of 2020

/in , , /by

According to the market track for the second quarter of 2020 published by UBI Research, the total OLED shipments in the second quarter were 107 million units, down 13.4% (QoQ) from 124 million units in the last quarter. In addition, it decreased by 16.6% (YoY) compared to the 122 million units in the second quarter of 2019. This is because sales of OLED set devices decreased due to the aftermath of COVID-19.

However, it was found that the OLED market for smartphones that support the OLED market was significantly affected by COVID-19 compared to the overall market.

OLED shipments for smartphones in the second quarter were 87 million units, down 17% from the previous quarter (QoQ), and 23.1% from the same quarter last year (YoY). Compared to the decline in overall OLED shipments, the decline in OLED shipments for smartphones is even greater. However, the reason for the decline in OLED shipments for smartphones is concentrated on rigid OLEDs.

Despite the sharp decline in OLED shipments for smartphones, flexible OLEDs grew 38% compared to the same quarter last year.

However, the YoY of rigid OLED shipments was -40.3%, a sharp decline from the same quarter last year.

The reason why the increase in flexible OLED for smartphones has soared and the shipments of rigid OLEDs have fallen sharply is because Chinese smartphone makers reduced production of mid-priced smartphones using rigid OLEDs and increased smartphone shipments using flexible OLEDs.

According to UBI Research’s CEO Choong Hoon YI, the reason Chinese smartphone makers have increased their flexible OLED smartphone shipments is: First, due to the influence of Apple, Chinese smartphone makers also use OLED for their flagship models. In particular, Chinese smartphone makers use the name plus or max, which are used by Apple and Samsung Electronics, for the highest-end specifications, and imitate that they are making a product that is equivalent to Apple and Samsung Electronics, which are the most recognized in the smartphone market. The second reason is that Chinese display makers have improved OLED manufacturing technology, allowing them to produce panels similar to Samsung Display’s OLED. In particular, it is because Chinese panel makers are supplying panels at 60% of Samsung Display’s price, so Chinese smartphone makers have increased the choice of flexible OLEDs. The third reason is that Chinese panel makers can supply OLEDs at low prices because of the Chinese government’s subsidy policy.

YI said that the OLED industry will become more active due to the increase in OLED usage by Chinese smartphone makers, but the growth of Samsung Display’s OLED business, which has maintained a monopoly position in the smartphone OLED market, may stop growing due to the increase in production of Chinese panel makers.

 

 

 

Supplied foldable OLED panels to CSOT T4, Motorola

/in , , /by

Recently, the panel maker COST T4 plant, a subsidiary of TCL Group, mainly produces premium flexible AMOLED displays, and already supplies them to Motorola foldable OLED phones and Xiaomi 10/10 Pro premium OLED phones.

 

In early 2019, TCL Group changed its company name to “TCL Technology” while reorganizing its assets and focused on the display panel business. The production capacity of TCL Technology, one of the LCD manufacturers with the largest production capacity in China, is showing rapid growth in recent years.

 

It is said that the CSOT shipment in 2019 was 22.84 million square meters, an increase of 23.8% from the same period last year. Among them, the flexible AMOLED T4 plant achieved the first stage of mass production in the fourth quarter of last year. CSOT expects that flexible products will be mass-produced within this year and will enter the market in large quantities.

 

At the same time, the spread of next-generation display technologies and materials is also strengthening. In 2019, the company invested 5.46 billion yuan in R&D and applied for 2,752 PCT international patent applications

Will Dowooinsys expand UTG lines to prepare for the foldable phone market?

/in , , /by

The cover window material of Samsung Electronics ‘Galaxy Z Fold 2’ which will be released in the second half of this year, is UTG like ‘Galaxy Z Filp’. The reason why Samsung Electronics prefers UTG is analyzed for its sense of luxury, differentiation, and sensitivity for the touch pen expected to be applied in the future.

In 2021, the market for over 10 million foldable phones is expected to expand, and the main cover window material of Samsung’s foldable phones will be UTG. To respond to this, Dowooinsys should increase their capacity.

Dowooinsys’ capa is estimated to be 250K/month for 6 inch cells and 375K/month for 7 inch cells. Even if the 6 inch line will be converted to a 7 inch line in the future, it will be 500K/month. Considering the yield of Dowooinsisy and Samsung Display’s Vietnamese module line, more than 4 to 5 lines should be expanded.

Currently, Samsung Display’s Vietnamese module line is assumed as 450K/month considering the yield, but the Vietnamese module line is continually being converted into a foldable line. Even in response to the current situation that Samsung Electronics prefers UTG, Dowooinsys is expected to expand more lines in the second half of this year, and its location is also expected to be considered near Samsung Display’s Vietnamese module line.

With the expansion of Dowooinsys’ additional lines, the market of cover window materials for foldable phones is expected to change in the future. At UBI Research’s ‘Next-Generation Display Technology and Industry Outlook Seminar’ held in mid-July, it is predicted that UTG will lead the future market at a ratio of 7:3 with colorless polyimide.

LPKF’s laser glass processing technology, makes a cover glass thicker than UTG be folded.

/in , , /by

It was expected that the S Pen would be applied to Samsung’s ‘Galaxy Z Fold2’, which will be released in the second half of this year, but it has passed the year.

UTG, the cover window material currently applied to Samsung Electronics’ ‘Galaxy Z Filp’, is 30 um thick and is 1/10 thinner than 300 um, the thickness of commercially available cover glass.

It was possible to have flexibility by using UTG into a foldable phone, but due to the film-like characteristics, there was an issue that durability was insufficient to apply the S Pen.

In order to handle this issue, a technology that increases the thickness of UTG and secures flexibility will be needed. A typical method is processing the folding part of the glass to get flexibility even at a thick thickness.

LIDE (Laser induced deep etching) technology, developed and patented by German high-tech company LPKF, is expected to be a good example. It is known that this technology is a two-step process called micro-region transformation and chemical treatment using a laser, and can process glass of various thicknesses from 30 um to 900 um without micro crack.

LPKF explains that the part where the cover glass is folded is finely processed with a laser to give flexibility to the glass, and it is possible to design the pattern to be invisible using a polymer having same reflectivity as a cover glass.

If you look at Vitrion’s YouTube video (https://youtu.be/Vh3rU4LRHaw), a separate brand related to LIDE, in LPKF, you can see that a cover glass with a thickness of 500 um was patterned to secure bending radius of 1 mm.

With this glass processing technology, attention is paid to whether a S-pen can be supported as a thicker cover glass is applied to a foldable phone in the future.

Material Science Co., Ltd. develops high-purity blue light-emitting material with a half width of 11 nm

/in , , /by

In OLEDs which are currently leading the display industry for mobile devices and TVs, blue material is still using fluorescent material unlike red and green.

Currently, a lot of light emitting material companies are trying to improve the efficiency, lifespan, and color purity of blue light emitting materials, also next-generation materials such as phosphorescence, TADF, and hyper-fluorescence as well as actively developing luminous efficiency by controlling emission wavelengths.

Material Science (hereinafter referred to as MS), a Korean company that has been developing blue light emitting materials since 2015, has recently focused on realizing high color purity and successfully developed high color purity blue light emitting materials with a light emission wavelength of 460 nm and a half width of 11 nm. Considering that the emission wavelength of the currently commercially available blue material is about 20 nm, the blue material of MS is expected to receive great attention.

The full width at half maximum (FWHM) is an expression of the extent of function given by the difference between the two extreme values of the independent variable at which the dependent variable is equal to half of its maximum value.

 

and the narrower the half width, the higher the purity.

A typical example is Samsung Electronics’ QLED TV, which has significantly improved color reproduction by applying a QD sheet to the LCD back light.

The blue light emitting material developed by MS is expected to be applicable not only to fluorescent materials but also to hyper-fluorescence, which is attracting attention as a next-generation blue material according to emission wavelength control.

Announcement of sale of Samsung LCD P8-2 line

/in , /by

Recently, Samsung’s announcement of the sale of the P8-2 LCD line in Tangjeong was posted (announced on June 29).

Samsung has been steadily selling the old LCD line until recently, but since it has never posted a sale announcement, it is unusual to post a notice on the sale of this P8-2 line.

 

Prior to this, some facilities of the P8-1 line were converted to the newly invested QD display line, and only about 30K of TFT and 200K of CF out of all 200K-scale process equipment were sold to companies in China.

Shenzhen EFONLONG OPTRONICS DISPLAY CO., LTD, which acquired Samsung P8-1 line equipment, was founded in 2008 as a manufacturer of LCD modules , located in shenzhen, China. Hefengtai is known to attract investment from the government of Zhejiang, China, and install and operate a relocation facility in Zhejiang.

 

On the other hand, this P8-2 is known to sell the entire 200K-scale facility, and it is known that Samsung C&T is in charge of it, and the sale amount reaches 500 billion won.

 

Samsung is known to preferentially convert existing LCD facilities in line with the investment of QD Display, but due to the announcement of the sale of all volumes, it is expected that most of the investment facilities will be newly purchased in the future.

 

In view of this information, it is possible to carefully predict the possibility of a delay in the investment schedule of an additional 90K scale after the current QD display 30K investment or a change in the investment direction associated with QNED development status.

Samsung Display A3 line replaced with Y-OCTA manufacturing line

/in , , /by

The touch panel technology installed on a mobile phone is an important element technology that performs a user interface function. Touch technology is changed from an add-on type to an on-cell type in flexible OLED displays.

The built-in method in which a touch sensor is formed on a thin film encapsulation (TFE) is called by various names such as Y-OCTA(YOUM on-cell touch AMOLED), ToE(touch on encapsulation) or FMLOC(flexible multi-layer on cell touch) for each panel maker. Unlike the add-on type, the on-cell type touch sensor is formed directly on the top of the encapsulation layer without a separate base film. Due to this, the on-cell type has a higher process difficulty than the add-on type, but it is advantageous to manufacture a thin OLED panel thickness, and there is an effect of reducing the process cost.

Recently, in order to apply this on-cell type touch technology to mobile phones using OLEDs, each display manufacturer is undergoing a step-by-step line modification work. Four mask steps are added to apply the on-cell type touch technology. There are two ways to cope with this process step increase: to install and respond to new equipment as much as the process to increase, and to proceed with the process at existing facilities.

Samsung Display decided to use an existing exposure machine to use the on-cell type touch technology in the existing A3 line (Tangjeong), and is in the process of remodeling the 105K capacity TFT production line. In the existing process flow, a back plane process is performed with mother glass of 1500×1800 mm2 and 1500×900 mm2 glass with half-cutting of this mother glass is processed in the OLED process. Therefore, in order to process the half-cut glass again in the back plane equipment, the jig manufacturing method of connecting and processing two cut sheets is applied. After this modification, the production capacity of the A3 line will be reduced. The amount of 105K of the A3 line that is currently being renovated is changed from LTPS process to LTPO process, and it is combined with Y-OCTA process. In this case, 3 mask steps increase as LTPS is changed to LTPO, and 4 additional mask steps increase for Y-OCTA. As a result of the total increase of 7 mask steps, the A3 line is expected to reduce the existing 105K production capacity to approximately 75K level after remodeling.

China’s BOE is also constructing built-in touch processes in B7 and B11. BOE is in the process of adding and processing exposure equipment, etc. as a way to add a built-in touch process. In this case, there will be no significant change in production capa.

Deuterium substitution blue, will be next generation blue materials?

/in , /by

Fluorescent blue emitting material is the only fluorescent material used in small and medium-sized OLEDs and large-area OLEDs.

Development of next generation emitting materials such as TADF and hyper-fluorescence is also in progress, but deuterium substitution technology has got attention since it is adopted to Samsung Galaxy S20.

Deuterium substitution technology is to replace hydrogen with deuterium in a compound combined with existing hydrogen, and each company has a difference in substituting the compound before or after synthesis or substituting the whole. Representative development companies for deuterium substitution include Idemitsu Kosan, DuPont, SFC, and JNC.

As related patents, compounds substituted with deuterium with an atomic mass of deuterium that is twice as high as hydrogen have lower zero-energy and lower vibrational energy than those combined with hydrogen, resulting in lower ground-state energy and weaker intermolecular interactions, resulting in a thin film in an amorphous state. It is effective in improving the life of OLED.

It is expected that the OLED device to which the deuterium-substituted compound is applied can improve the lifetime by more than 20% compared to the previous one.

Samsung’s QNED, will make a sensation in the TV and display markets?

/in , , /by

QNED (Quantum dot nanorod LED), which is known to be under development by Samsung, is becoming a hot issue in the display industry in 2020.

With the emergence of micro LEDs, followed by CRTs, PDPs, LCDs, and OLEDs as TV displays, the industry is interested in whether QNED could be another new technology.

Samsung Display is known to stop the LCD business and invest 13.1 trillion won as an alternative to do the QD-OLED business. In this situation, attention is being focused because the development of QNED can act as another variable in the future of Samsung Display’s large display business.

QNED uses oxide TFT and QD (quantum dot) -CF (color filter) technologies used in QD-OLED manufacturing. On the other hand, the pixel material that emits light is characterized by being changed to a nano-sized bar-type LED (nanorod LED), unlike OLED emitting materials. The pixel manufacturing technology, which is the core technology of QNED manufacturing, is a method of spraying nanorod LEDs dispersed in a solution into a pixel area by an ink jet method and arranging them in a self-align method by an electric signal.

UBI Research published a report that analyzed the structure and manufacturing technology of QNED based on the patented technology filed by Samsung Display. This report is structured to quantitatively analyze QNED-related patents filed by Samsung Display, so that QNED’s technology completeness and mass productivity can be known.

QNED structure and manufacturing technology analysis report published

/in , , /by

UBI Research (www.ubiresearch.com) published “QNED Structure and Manufacturing Technology Analysis Report”, which analyzed 41 cases of Samsung Display’s QNED (quantum dot nanorod LED) published patents.

The contents described in this report were selected from the 41 patents published, which are considered to be used for QNED manufacturing, and are constructed by qualitative analysis.

As a result of analyzing the published patent, the QNED structure was formed of TFT, pixel, and QD (quantum dot) -CF (color filter). In the published patent, all TFT structures are depicted as 2Tr (transistor), but it is estimated that a 3Tr1C structure will be used because at least three TFTs for current driving are required. The pixels consisted of nanorod LEDs, electrodes, and optical structures to increase light efficiency.

Until now, the electrode structure of the pixel was known to be rectangular, but as a result of analyzing published patents, the electrode structure is estimated to be circular. In a specific patent, when the asymmetric waveform was applied to the circular electrode, the alignment direction and alignment characteristics of the nanorod LED were improved. It is judged that the nanorod LED alignment electrode and the drive use the same electrode.

The nanorod LED used for QNED manufacturing is made of GaN and emits blue light, and the size is <1um x 10um. In order to increase the alignment effect of the nanorod LEDs and reduce process defects, the nanorod LED surface appears to be treated with an insulating film and an orientation radical.

What is the difference between the touch types of each model of iPhone 12?

/in , , /by

All of Apple’s iPhone 12 models, OLED panels will be used and consisted of four models. There are three sizes, 5.4 inches, 6.1 inches, and 6.7 inches, respectively, and 6.1 inches are divided into two models.

Samsung Display and LG Display have begun preparing to mass-produce, with recent orders from Apple. Samsung Display plans to supply OLED panels of all sizes, LG Display plans to supply 6.1-inch OLED panels, and there are differences in touch type by size.

First, on-cell touch which a touch electrode is formed on a thin film encapsulation (TFE) is applied to 5.4 inch and 6.7 inch models. Each panel maker is called Y-OCTA (YOUM on-cell touch AMOLED), ToE (touch on encapsulation), FMLOC (flexible multi-layer on-cell touch), and unlike add-on touch, a touch electrode is formed directly on the upper layer without base films. Due to this, the on-cell touch has a higher process difficulty than the add-on touch, but it is advantageous to fabricate a thin OLED panel thickness, and the process cost is also reduced.

Add-on method is applied to 6.1 inches. A touch electrode is formed on the base film, and is attached on the TFE by adhesive. It has the advantage that the process is simpler than on-cell touch.

<Image of iPhone 12 Pro Max, Source: EveryApplePro>

Apple’s new iPhone 12 will be consisted of 4 models, and all 4 models are expected to adopt OLED. The general lineup of the iPhone 12 is the 5.4 inch iPhone 12 and the 6.1 inch iPhone 12 Max, and the pro lineup is the 6.1 inch iPhone Pro and the 6.7 inch iPhone Pro Max.

Recently, rumors are floating that BOE will supply OLED of 5.4 inch and 6.1 inch general models, and Samsung Display will supply OLED of 6.1 inch and 6.7 inch pro models. Due to the news that Chinese OLED panel manufacturer BOE is supplying OLEDs to Apple, the interest of OLED-related companies such as light-emitting material companies and component companies is growing day by day.

According to UBI Research, BOE is developing 5.4 inch and 6.1 inch OLEDs, but has not received any calls from Apple. In the current situation, Samsung Display plans to supply 5.4 inch, 6.1 inch, and 6.7 inch OLEDs, and LG Display and BOE are developing 6.1 inch OLEDs.

The BOE hasn’t gotten a clear call yet, but there’s plenty of time left for the mass production of the iPhone 12, so there’s plenty of room for the BOE to get a call from Apple. While the production of the iPhone 12 is likely to be delayed by about a month due to the corona incident, it usually takes 4 ~ 5 months from the OLED panel test to the mass production of the set, so there is enough time.

78.6 tons of OLED emitting material demand increased by 5.6% in 2020

/in , , /by

According to the 2020 OLED emitting material report published by UBI Research, the demand for emitting materials in 2020 is 78.6 tons, which is 4.2 tons higher than last year’s 74.4 tons. The material used for OLEDs for smartphones and mobile devices is 62.9 tons, and the OLED emitting material for TVs is expected to be 15.7 tons.

In 2019, the total emitting material market was totaled at $ 1.28 billion, and 43% of the total amount was purchased from Samsung Display. It was found that the amount purchased by LG Display was 19.4% and the BOE was 11.6%. LG Display’s purchase of emitting materials accounted for 60.8% of TV use. The order of purchase of emitting materials for mobile devices is in order of Samsung Display, BOE, and LG Display. This is because BOE has a large amount of OLED production for mobiles after Samsung Display.

The OLED panel for TV only produces LG Display, but Samsung Display is pursuing QD-OLED commercialization using blue light emitting material and QD. In addition, although BOE is a white OLED structure similar to LG Display, it is developing a top-emission structure that transmits light in the opposite direction of TFT, and it is expected that three companies will produce OLED panels for TV within a few years, and the emitting material market is expected to increase as well.

 

The market for emitting materials in 2020 is expected to increase by 7% from 2019 to $ 1.37 billion. Among the emitting materials, green and red hosts are expected to be $ 19.2 billion and $ 19 billion, respectively, and green dopants and P + are expected to be $ 1.37 billion and $ 1.35 billion, respectively.

2020 OLED market change by coronavirus

/in , , /by

According to UBI Research’s report on changes in the OLED market caused by coronavirus, the forecast for the 2020 OLED modification market is $ 36.7 billion in sales and 612 million units. This is a decrease of 4.8% and 7.6%, respectively, from the expected sales of $ 38.5 billion and shipments of 6.6 million units at the beginning of the year.

As a result of UBI Research’s analysis of the effect of coronavirus on the OLED market for two months, the global smartphone market is expected to drop by 20% and the TV market is expected to decrease by 15%. However, the impact on the overall OLED industry was judged to be only 5-8%. OLED panels for smartphones, TVs and watches are expected to decrease, but the market for OLEDs for monitors is expected to increase.

The expected OLED shipment for smartphones was 527 million units at the beginning of the year, but the forecast for correction is 486 million units, a decrease of only 7.8%. Although the market for Galaxy and iPhone is analyzed to be higher than the average decrease rate, Chinese smartphone makers are expected to reduce LCD smartphones and increase production of OLED smartphones significantly.

Chinese smartphone makers’ use of OLED seems to follow Apple’s business direction. Flagship models of Chinese smartphone makers have used Pro and Pro Plus. Pro is the model grade name used by Apple and Plus is the model grade name used by Samsung. However, flagship models of Chinese smartphone makers that are launching this year are using both Pro and Pro Max as well as Apple. All of these models, like Apple, plan to use flexible OLEDs.

The OLED TV market was found to be greatly affected by coronavirus. Estimated shipments at the beginning of the year were 4.9 million units, but the forecast for correction was 3.6 million units, down by 1.3 million units. A 26.5% reduction is expected. This is 300,000 units more than 2019 shipments. This is because the production schedule of the Guangzhou factory has been postponed since the third quarter due to the coronavirus, and TV sales are plunging due to the spread of coronavirus in Japan and Europe, the main markets for OLED TV. In fact, Japan’s TV performance in the second quarter was below 50% in 2019.

However, the demand for the OLED panel business for monitors that Samsung Display has been promoting since the second half of last year is expected to increase due to the game industry, telecommuting, telemedicine, and remote classes due to the aftermath of the coronavirus.

Apple’s last LCD phone, iPhone SE

/in , , /by

The iPhone SE, the last product of the LCD smartphone that Apple has opened to the smartphone market, has been released.

Apple’s 2019 model iPhone 11 had three models, the base model iPhone 11 used a 6.06inch LCD, and the advanced specifications iPhone 11 Pro and Pro Max used 5.85 inch and 6.46inch flexible OLED, respectively.

Samsung Display supplies both 5.85inch and 6.46inch flexible OLEDs, and LG Display has supplied only 6.46inch flexible OLEDs from the fourth quarter of 2019.

This year, Apple releases a four-model iPhone. There are three types of iPhone, SE2 which started selling this month, and 3 iPhone 12 which starts selling in September. Strictly speaking, since there are 2 models of the iPhone 12 Pro, 4 types of iPhones using OLED will be released in the second half of this year.

Apple’s current LCD phones are the iPhone 11 and the newly released SE2. Of the iPhone models released by Apple this year, only the LCD will use the SE2, and the SE2 is expected to be Apple’s last LCD smartphone.

Apple already mentioned that in 2019, all future iPhone displays will be replaced by OLEDs. Therefore, in fact, this is the reason that the SE2 released this time is expected to be the last　LCD phone.

Most of the latest smartphones are more than 6 inches, but the iPhone SE2 released this time is a small 4.7-inch model using IPS LCD.

The reason Apple used a small display is believed to be a strategic product to target the mid-priced market of around $ 500. It’s currently $ 549.99 on eBay, but it’s on Amazon for $ 399.

Apple’s expected iPhone strategy is two tracks. First of all, in order to maintain the second largest market share in shipments, it is necessary to match shipments with products with a wide market of $ 500. And the operating profit creation is to fit the expensive iPhone 12 series using flexible OLED.

However, shipments of LCD phones are expected to gradually disappear after 2021, depending on the sales of 5.42 inches, the basic model of iPhone 12, which will be released in the second half of this year.
