한국 디스플레이 패널 사업이 5분기간의 약세를 끝내고 성장세를 뚜렷하게 나타내고 있다. 삼성전자와 LG디스플레이의 2015년 1분기 실적 발표에 의하면 한국 디스플레이 1분기 매출 합계는 14.07조원으로서 지난 분기에 비해서는(QoQ)  -9%를 기록하였지만 지난 해 동 분기 대비(YoY) 20% 상승하였다.최근 2년간 가장 실적이 나빴던 분기는 2013년 4분기였다. 크리스마스 시즌이 있는 4분기는 계절적 수요에 의해 가장 실적이 좋은 것이 일반적인 흐름이나 2013년은 오히려 3분기보다 실적이 떨어졌다. 하지만 2014년은 매 분기 매출이 증가하며 일반적인 흐름에 따르는 결과를 보여주고 있다.

이번 분기 실적에 의하면 2015년 한국 디스플레이 패널 사업은 성장 패턴에 속할 것으로 분석된다. 이번 분기와 지난 분기의 YoY가 각 각 1년 전 동 분기에 비해 14%와 20%의 성장을 보여주고 있기 때문이다.

최근 한국 디스플레이 사업이 회복세를 나타내고 있는 것은 LG디스플레이의 실적이 지속적으로 상승하고 있기 때문이다. 양사의 매출 점유율은 3분기 연속 LG디스플레이가 50% 이상을 차지하며 시장을 이끌고 있다.

LG디스플레이의 실적 향상은 Apple iPhone 6 실적 향상에 기인하는 것으로 분석된다. 하지만 iPhone6의 출하량이 증가할수록 경쟁업체인 삼성전자의 Galaxy 실적이 하락할 가능성이 높아 삼성디스플레이의 실적 역시 둔화될 수 있다.

하지만 세계 최대 smart phone 제조사인 삼성전자와 Apple의 시장 점유율에 따라 양사에 디스플레이를 공급하는 삼성디스플레이와 LG디스플레이의 실적에 희비가 갈리겠지만, 한국 디스플레이 산업은 두 회사를 통한 꽃놀이 패를 가지고 있기 때문에 디스플레이 산업은 지속 성장을 유지할 것으로 예상된다.

LG Electronics, Not Selling OLED TV? Or Can’t Sell?

/in /by

OLED TV business that LG Electronics ambitiously prepared for is remaining at a standstill for more than 2 years. Korean media is reporting that the OLED TV sales in Korea reached 3,000 units per month, but this figure is too weak.

 

The money that LG Display have invested in line establishment for OLED panel for TV is already exceeding approx. US$ 1,400,000,000. Annual depreciation cost for equipment investment alone, excluding cost of labor and material, is approx. US$ 280,000,000.

 

Considering the current cost for FHD OLED TV is approx. US$ 1,800 – 3,300, monthly sales of 3,000 units in Korea only result in approx. US$ 9,400,000. With approx. 10,000 units per month being sold in the world, monthly revenue is merely US$ 23,000,000.

 

Although LG Display is aiming for 600,000 units of OLED panel for TV shipment this year, with LG Electronics’ first quarter world OLED TV sales of approx. 30,000 units, there is concern that only 100,000 – 200,000 units will be sold in 2015.

 

It is difficult to understand whether this uncommonly low sales of LG Electronics’ OLED TV is because they are not selling them or unable to sell them.

 

It seems plain that the initial price of OLED TV in 2013, approx. US$ 14,000, was set in order to not sell. LED TV at the time was being sold at approx. US$ 2,800, and the 5 times more expensive price was too high to be considered a normal premium price. Consequently, the 2013 OLED TV market stopped at around 10,000 units, and in 2014 remained around 100,000 units.

 

At this point, feasible production rate for LG Display’s 55 inch FHD OLED panel needs to be compared. In 2013, LG Display’s M1 line yield rate was approx. 40% with annual possible production of 50,000 – 100,000 units. As the yield rate increased to 80% in 2014, it is estimated that 200,000 units or more would have been produced.

 

Compared to LG Display’s investment cost and production potential, the LG Electronics’ OLED TV sales results are too shabby.

 

Of course, as the current main product on the market is FHD, when the newly released UHD OLED TV market actively opens the figures could always change. However, with 55 inch UHD OLED TV having to compete with Samsung Electronics’ SUHD TV, the market is not so easy. SUHD TV costs approx. US$ 3,700, and UHD OLED TV costs about 25% more with US$ 5,100.

 

Compared to the initial price of FHD OLED TV, approx. US$ 14,000, 2 years ago the UHD OLED TV price is low enough to be quite reasonable. However, with the performance of past 2 years it appears that LG Display might be inadequate to widely open the OLED TV market.

 

It makes one wonder how Samsung Electronics became the world leading company with their OLED panel equipped Galaxy series achieving 20% mobile market share, a market that used to be dominated by LCD panel.

LG전자, OLED TV 안 파나? 못 파나?

/in /by

LG전자가 야심차게 준비한 OLED TV 사업이 2년이 지나도록 답보 상태에 머물고 있다. 최근 한국 매체에서 한국에서 OLED TV 판매량이 월 3,000대에 달했다고 보도하고 있지만, 이 숫자는 너무 미약하다.

LG디스플레이가 TV용 OLED 패널 라인 구축에 투자한 돈은 이미 1조 5천억원을 넘어가고 있다. 인건비와 재료비 등을 제외한 장비 투자에 대한 연간 감가상각 금액만도 3,000억원이다.

FHD OLED TV 가격이 현재 200만원~350만원 정도인 것을 감안하면 국내 월 3,000대 판매 금액은 약 100억원에 불가하다. 현재 LG전자가 전세계에 판매하고 있는 월 약 10,000대 정도이기 때문에 월 매출은 겨우 250억원 정도이다.

LG디스플레이가 올해 목표로 하고 있는 TV용 OLED 패널 출하량은 60만대이나, LG전자의 1사분기 OLED TV 판매량이 전세계 약 30,000대 정도이기 때문에 2015년 예상 판매량 10~20만대에 불가 할 것으로 우려된다.

LG전자의 OLED TV 매출이 매우 적은 것은 안 팔기 때문인지, 못 팔기 때문인지 이해하기 힘들다.

분명 OLED TV가 처음 나온 2013년의 1,500만원이라는 숫자는 안 팔려고 한 금액이었을 것이다. 당시 LED TV 가격이 약 300만원 정도였기 때문에 5배나 높은 가격은 통상적인 프리미엄 가격이라고 받아 들이기에는 너무 높은 가격이었다. 그 결과 2013년 OLED TV 시장은 1만대 정도에 그쳤고, 2014년은 약 10만대 수준에 머물렀다.

이 시점에서 LG디스플레이가 생산 가능한 55인치 FHD OLED 패널 생산 가능량은 어느 정도인가를 비교해 볼 필요가 있다. LG디스플레이의 2013년 M1 라인 수율은 약 40%였기 때문에 연 생산 가능량은 적어도 5만대, 많으면 10만대 수준이었고, 2014년에는 80%에 도달했기 때문에 20만대 이상이었을 것으로 추정된다.

LG디스플레이의 투자비와 생산 가능량에 비교하면 LG전자의 OLED TV 판매 실적은 너무 초라하다.

물론 현재 팔고 있는 주요 제품은 FHD급이기 때문에 새로 출시된 UHD OLED TV 시장이 본격적으로 열리면 수치는 언제든지 변할 수는 있다. 하지만 55인치 UHD OLED TV는 삼성전자의 SUHD TV와 경쟁해야 하기 때문에 만만치 않은 시장이다. 두 제품의 가격은 SUHD TV가 약 400만원이며, UHD OLED TV는 이 보다 약 25% 정도 높은 550만원 정도이다.

FHD OLED TV 초기 가격이 1,500만원 정도였던 2년전과 비교하면 UHD OLED TV 가격은 매우 합리적인 가격 수준으로 내려왔다. 하지만 지난 2년간의 과거 실적으로서는 LG전자가 OLED TV 시장을 화~알 짝 열기에는 역부족인 것 같다.

삼성전자가 LCD 패널이 주력이었던 smart phone 시장에서 OLED 패널을 탑재한 Galaxy로서 세계 시장의 20%를 점유하며 시장 1위를 차지할 수 있게 된 이유가 새삼 궁금해진다.

 

LG Display Reports Performance, Focus on Structure Differentiation Through OLED TV

/in /by

On April 22, LG Display reported their first quarter of 2015 performance announcing their success in OLED TV market entrance with balanced results in mass production yield rate, timing, and management. They also revealed their panel production targets of 600,000 units this year, and 1,500,000 units in 2016.

 

LG Display’s CFO Sang-don Kim announced that “OLED TV was about technology innovation until last year, this year it will be innovation in consumers and yield rate, and by next year it will be decided whether it has popularization potential”. He added LG Display will “focus on increasing the business values rather than immediate profit and methodically proceed with OLED focused strategy for structural differentiation in large size display”. He also revealed LG Display will decide on additional investment after observing OLED TV market’s growth potential.

 

Regarding China’s BOE Gen10.5 investment, a recent issue, he forecast “much time is needed to begin set up and if Chinese companies run into problems while working on enlarging the display it is estimated that they will return to 30inch. Therefore LG Display’s large area panel sales will not be much affected”. He explained in regards to LG Display’s Gen10.5 large area LCD investment that it will be decided after careful examination considering the cost and market maturity.

 

LG Display also revealed a decrease in sales in small to mid-size display, such as tablet, due to seasonal factors. However for large size display, they announced as a result of improved performance, the total business profit recorded approx. 687 million USD, an 11% increase compared to the previous quarter (approx. 578 million USD), and showed surplus in business profit for the 12 consecutive quarters.

LG Display 실적 설명회 개최, OLED TV로 구조 차별화에 집중

/in /by

LG Display는4월 22일 여의도 트윈타워에서 열린 2015년 1분기 실적 설명회에서 OLED TV의 시장 진입에 대해 양산 수율과 시기, 경영이 적절하게 조화된 성공적인 진입이라고 밝히며 panel 생산 목표는 올해 60만대, 내년 150만대라고 밝혔다.

이날 실적 발표회에서 LG Display CFO 김상돈 전무는 “OLED TV는 작년까지는 기술의 혁신, 올해는 고객과 수율의 혁신으로 내년까지 대중화의 가능성이 있는지가 판가름 날 것”이라며, “당장의 이익을 추구하기 보다 사업가치를 올리는데 집중할 것으로, 대면적 디스플레이에서 구조의 차별화를 위해 OLED에 집중하는 전략을 차근차근 진행할 것”이라 말하였다. 또한 OLED TV시장의 성장성을 보고 추가 투자에 대한 결정을 할 것이라 밝혔다.

최근 이슈가 되었던 중국 BOE의 Gen10.5 투자와 관련해서는 “셋업에 들어가기 위한 시간이 상당히 많이 필요할 것으로, 중국 업체들이 대면적화를 진행하는 도중 어려움에 봉착되면 30inch 생산으로 돌아갈 것으로 예상된다. 따라서 LG Display의 대면적 panel 매출에 큰 영향을 끼치지는 않을 것”이라고 전망하였다. LG Display의 Gen10.5 대면적 LCD 투자에 대해서는 cost 문제와 시장 성숙도를 고려해서 신중한 결정할 예정이라 밝혔다.

한편 LG Display는 태블릿 등 중소형 디스플레이에서는 계절적 요인에 의한 매출 감소가 있었으나, 대면적 디스플레이에서는 실적 호조로 전체 영업이익은 전분기(6,260억원) 대비 11% 오른 7,440 억원으로 12분기 연속 영업이익 흑자를 기록했다고 발표하였다.

[Analyst Column] The Reason Samsung Must Undertake OLED TV and Technology Course Analysis

/in , /by

Yi Choong Hoon Yi, Chief Analysis / UBI Research

In 2014, as the revenue and business profit fluctuated greatly per quarter, Samsung Display carried out management evaluation with BCG. One of the conclusions is known to be Gen10 LCD investment together with large area OLED for TV investment.

Gen10 LCD line investment is seen to be a countermeasure against Chinese display companies that continue their aggressive investment and display industry that is expanding in information society. It is analyzed that the large area OLED line investment is to prepare for the OLED TV market growth which has superior picture quality compared to LCD and to control their biggest rival company LG’s WRGB OLED TV market expansion which is maintaining their investment.

These two plans are obvious conclusions that any display expert can draw.

However, any experts who know Korea’s display would recognize that Gen10 LCD line investment is not suitable for Korea. This is because even if Korea expands the market share by investing in Gen10 LCD line they will still be weak against Chinese display companies in price. Korean display companies only sell high quality goods and 90~95% is the limit of yield rate. In comparison, in China the size of the population who can easily purchase expensive high quality TV and the consumers who demands lower priced goods are both huge; faulty display panels have a place in Chinese market. Chinese display companies can also sell lower quality panels through close relationship with lower price TV production companies with factories in China. Theoretically, this can lower the panel price as yield rate close to 100% can be achieved. Furthermore, support from Chinese government and cheap factory construction cost increases price competitiveness of Chinese display companies even more.

The reason Japanese display companies had no choice but to give up LCD market to Korean display companies was also because they could not continue LCD investment with their difficulty in price competitiveness. Although Sharp vigorously continued investing until Gen10 line, the result was decision to sell small size LCD line for mobile device due to the accumulated deficit.

If Samsung Display decides on Gen10 investment, it is highly likely that they will follow similar path to Sharp’s, increasing the risks rather than sales. It is more effective for Samsung Electronics to lead TV industry using Chinese companies’ cheap LCD panel with good definition rather than producing TV using expensive Korean LCD panels with good picture quality. The fact that there are no comments regarding Gen10 investment within Samsung Display can be interpreted that there are experts with good understanding of display industry.

Unlike the current Samsung Elec. business strategy where the focus is exclusively on quantum dot technology applied LCD SUHD TV, the large size line investment decision for OLED TV production is a conclusion that requires change in Samsung’s business strategy. In CES 2015, Samsung Elec. exhibited SUHD TV and OLED TV in comparison and highlighted LCD TV’s superiority in picture quality. If SUHD TV is more competitive than OLED TV, it is not worth investing any further.

However, the story is different in smart phone market. This is because Samsung Elec.’s flagship model Galaxy series all use AMOLED. One of the differentiation strategies that Samsung Elec. is using when selling Galaxy series is OLED. Wireless department of Samsung Elec. expanded the market share to 20% using the smart phone with the word ‘OLED’ attached. Most recently, flexible OLED applied Galaxy S6 Edge is hugely popular.

Samsung Elec.’s smart phone business department, IM, is recording twice the amount of revenue of VD business department that produces TV. Therefore that VD department’s marketing method of emphasizing OLED has worse definition than LCD is contradictory since IM department is marketing their product by valuing the superior picture quality of OLED over LCD. If QD-LCD is good then obviously the panel for Galaxy S series also has to be replaced to QD-LCD. Insisting that OLED has better picture quality in smart phone and LCD is superior in TV is mutually incompatible. This kind of dual behavior could result in Samsung Elec.’s rationales to be considered as ones by the boy who cried wolf. For the future expansion of Samsung Elec.’s smart phone market, VD department also has to produce OLED TV and establish the equation of ‘Samsung Elec. = OLED’ in order to complete the business strategy.

This is the reason Samsung must undertake OLED TV.

Nevertheless, problems are numerous. OLED TV produced by Samsung Elec. in 2013 was deemed to be marginally inferior in terms of completeness and picture quality compared to LG Electronics’ OLED TV by UBI Research’s Picture Quality Analysis Report and an article in OLEDNET. Since then Samsung Elec. halted OLED TV production practically acknowledging that their own OLED TV could not compete against LG Elec.’s product. The reason for this could be attributed to TV’s lower completeness but the fundamental reason lied in the fact that Samsung Display’s RBG OLED panel production method and characteristics could not compete against LG Display’s WRGB OLED in picture quality and competitiveness.

RGB OLED for Large area uses fine metal mask similar to small size AMOLED, and therefore OLED panel production is not possible using Gen8 mother glass and has to use evaporator for Gen8 glass cut into 6. As LG Display’s WRGB OLED manufactures pixels using white OLED with color filter fine metal mask is not required which allows for OLED panel production in Gen8 without cutting. Compared to the fact the rival company LG Display is using 1 Gen8 evaporator, Samsung Display requires 6 evaporators. The increased number of evaporators obviously leads to an increase in investment cost and the panel production cost cannot but be higher than LG Display.

Even in TFT production cost, Samsung Display is weaker in comparison to LG Display. LTPS-TFT process used by Samsung Display requires 8~9 mask processes but LG Display is using oxide TFT which needs 4~5. Therefore, it has an advantage of minimizing the investment cost when LCD line is transformed to OLED line. For Samsung Display to transform existing LCD line to OLED line, they have to add a huge amount of capital to the LTPS-TFT production. If they transform the existing 200K LCD factory to OLED line, the capa. also decreases to 90K, but LG Display can maintain the 200K volume without any loss. When OLED is produced transforming the existing LCD line, LG Display does not need additional factory construction but it is calculated that Samsung Display has to build another factory of equal size.

In encapsulation process, LG Display, which uses hybrid encapsulation technology, remains advantageous. This completes the OLED panel production by attaching adhesive film laminated metal foil on top of passivation which is a moisture proof structure made with 2~3 layers of passivation after OLED device production. The OLED panel for TV that was mass produced by Samsung Display in 2013 also used hybrid encapsulation structure. The difference was that the top substrate was glass. However, as Samsung Display was accused by LG Display for appropriating their encapsulation technology, Samsung is currently developing dam & fill method of hybrid encapsulation technology. Samsung Display’s dam & fill hybrid encapsulation technology shares the part of forming passivation layer on top of device with LG Display. However, after that Samsung Display applies curing agent using ODF (one drop filling) method to the dam made with organic materials on the outside of the panel. They then attach the glass substrate and harden. Although it would be better if the dam production could occur simultaneously as PDL (pixel define layer) process, generally as PDL layer is on top of TFT and dam structure is on the outside of the panel, height difference could develop leading to difficulty in upper substrate attachment. Furthermore, if the dam height is lower than PDL’s, it is unfavorable for the curved design which is the latest TV trend. Accordingly, if the dam formation process ensues after passivation is complete, further mask process is necessary which increases cost due to the added equipment investment. Samsung Display’s encapsulation process is a continuous operation whereas LG Display’s process can attach the coring film to the metal foil and send the selected high quality products to attachment process; for yield rate management, LG Display is better suited. Dam & fill method has to fill the liquid curing resin first before the attachment of upper substrate. This means that several hundreds of um thickness of glass substrate attachment is more appropriate rather than attaching metal foil of dozens of um thickness. In that case, metal foil cannot be used and additional heat sink materials are required. In encapsulation process, LG Display technology is better for mass production and has an advantage of being able to lower the production cost.

In conclusion, for Samsung Display to re-enter OLED panel for TV industry, rather than using their existing technology of LTPS-TFT, RGB OLED, and damn & fill encapsulation, it is better to use the technology being used by LG Display such as oxide TFT structure, WRGB OLED structure and lamination method of encapsulation structure that uses adhesive film.

To challenge large area OLED panel industry again, Samsung Display placed the existing large area OLED team under research lab led by their top OLED expert SungChul Kim. Although there has been no official discussion regarding OLED panel production technology directional course, using the same technology as LG Display’s would be advisable in order to succeed.

In terms of resources, Samsung Display, with their many years of OLED panel mass production experience and several thousands of top quality OLED engineers, is superior compared to LG Display.

Only the patents and decision making processes are left.

[Analyst Column] 삼성이 OLED TV를 할 수 밖에 없는 이유와 기술 개발 방향 분석

/in /by

이충훈, 유비산업리서치 수석 애널리스트

2014년 삼성디스플레이의 매출 실적과 영업 이익이 분기에 따라 심각하게 요동치자 연말에 BCG 컨설팅과 함께 경영 진단을 실시했다. 결론 중 하나는 Gen10 LCD 투자와 함께 TV용 대면적 OLED 투자로 알려져 있다.

Gen10 LCD 라인 투자는 정보화 사회로 인해 확장되는 디스플레이 산업과 공격적인 투자를 지속하는 중국 디스플레이 업체들에 대한 대응 방안이며, 대면적 OLED 라인 투자는 LCD 보다 화질이 우수한 OLED TV 시장 확대에 대비하고 투자를 지속하고 있는 최대 경쟁 업체인 LG의 WRGB OLED TV 시장 확장을 견제하기 위한 전략으로 해석된다.

이 두 가지 방안은 디스플레이 전문가라면 누구나 도출할 수 있는 당연한 결론이다.

그러나 한국의 디스플레이 전문가라면 Gen10 LCD 라인 투자는 한국 실정에는 맞지 않음 또한 누구나 알고 있다. 이유는 한국에서 Gen10 LCD 라인을 투자하여 시장 점유율을 확대해도 중국 디스플레이 업체에 대한 가격 경쟁력이 약하기 때문이다. 한국 디스플레이 기업들은 양품만 판매하고 있어 최대 수율은 90~95가 한계이나, 중국 시장은 소비자층이 고가의 TV를 쉽게 구매할 수 있는 부유층과 저가 제품을 요구하는 소비자층 또한 그 숫자가 막대하여 불량이 있는 디스플레이 패널도 시장에서 팔릴 수 있는 특성을 보유하고 있다. 중국 디스플레이 업체들은 자국 내에서 공장을 가지고 있는 저가형 TV 생산 업체들과의 긴밀한 유대관계를 통해 상대적으로 품질이 떨어지는 패널 또한 팔 수 있다. 이론적으로는 100%에 가까운 수율을 확보할 수 있어 패널 가격을 낮출 수 있다. 더불어 중국 정부의 지원과 값싼 공장 건설비용은 중국 디스플레이 업체들의 가격 경쟁력을 한층 더 높여 준다.

일본 디스플레이 업체들이 한국 디스플레이 업체들에게 LCD 시장을 양보 할 수 밖에 없었던 이유 역시 한국 기업과의 가격 경쟁력 확보가 어려웠기 때문에 LCD 투자를 지속할 수 없었기 때문이다. Sharp는 Gen10 라인까지 공격적으로 투자를 지속하였지만 결과는 누적되는 적자로 인한 모바일 기기용 소형 LCD 라인 매각 결정이다.

삼성디스플레이가 Gen10 투자를 결정하면 아마 Sharp와 유사한 길을 걷게 될 가능성이 매우 높아 매출 증대 보다는 리스크가 증대되기 쉽다. 삼성전자는 화질은 우수하나 가격이 높은 한국 기업의 LCD 패널로서 TV를 만드는 것보다 가격이 낮으면서도 화질이 우수한 중국 기업들의 LCD 패널로서 TV 사업을 끌고 가는 것이 보다 효과적이다. 삼성디스플레이 내에서 Gen10 투자에 대한 이야기가 나오지 않는 것은 디스플레이 산업을 잘 이해하고 있는 전문가들이 있다는 증거로 해석된다.

Quantum dot 기술을 적용한 LCD TV인 SUHD TV에 총력을 기울이고 있는 현재의 삼성전자 사업 전략과 달리 OLED TV 생산을 위한 대형 라인 투자 결정은 삼성의 사업 전략 변화를 요구하는 결론이다. 삼성전자는 CES2015에서 SUHD TV와 OLED TV를 비교 전시하여 LCD TV가 OLED TV 보다 화질이 우수함을 강조했다. SUHD TV가 OLED TV 보다 경쟁력이 높으면 굳이 투자할 가치가 없다.

하지만 smart phone 시장으로 넘어가면 이야기가 달라진다. 삼성전자의 플래그 쉽 모델인 Galaxy 시리즈는 모두 AMOLED를 사용하고 있기 때문이다. 삼성전자가 Galaxy 판매에 사용하고 있는 차별화 전략 중 하나가 바로 OLED이기 때문이다. 삼성전자 무선 사업부는 “OLED”라는 단어가 들어간 smart phone으로서 전세계 마켓 쉐어를 20%까지 확장했다. 최근에는 flexible OLED를 사용한 Galaxy S6 edge가 초인기를 누리고 있다.

TV를 생산하는 삼성전자의 VD 사업부 보다 2배 이상의 매출을 내고 있는 smart phone 사업부인 IM은 OLED가 LCD 보다 화질이 우수함을 장점으로 사업을 진행하고 있어 OLED가 LCD 보다 화질이 낮다고 강조하는 VD 사업부의 마케팅 방식은 삼성전자 스스로가 제품 판매에 대단한 모순을 가지고 있다. QD-LCD가 좋으면 Galaxy S 시리즈도 당연히 QD-LCD 패널로 대체해야 할 것이다. Smart phone에서는 OLED 화질이 우수하고 TV 에서는 LCD가 우수하다는 것은 제품에 따라 논리를 바꾸는 매우 이율 배반적인 부분이다. 이러한 이중적인 행태는 소비자가 삼성전자 이야기는 믿을 수 없는 “양치기 소년”으로 전락시키는 결과를 낼 수도 있다. 향후 삼성전자의 smart phone 시장 확대를 위해서는 VD 사업부에서도 OLED TV를 생산하여 “삼성전자 = OLED”라는 등식이 성립해야 완전한 사업 전략이 구축된다.

이것이 바로 삼성이 OLED TV를 해야 하는 이유이다.

그러나 문제는 산적해 있다. 2013년에 생산한 삼성전자의 OLED TV는 LG전자 OLED TV에 비해 완성도와 화질이 낮음이 유비산업리서치의 화질 보고서와 OLEDNET 기사에 의해 제기되었고, 그 후 삼성전자는 OLED TV 생산을 중지하였다. 사실상 LG전자 제품 보다 자사의 OLED TV가 경쟁력이 없음을 시인한 것이다.

이유는 TV 완성도가 낮았음도 있지만 근본적인 이유는 삼성디스플레이가 제조하는 RGB 구조의OLED 패널 제조 방식과 특성이 LG디스플레이가 생산하는 WRGB 구조의 OLED에 비해 생산성과 화질에서 경쟁력이 없었던 것이다.

RGB OLED는 소형 AMOLED와 유사하게 fine metal mask를 사용하기 때문에 현재 기술로서는 Gen8 원장의 유리로서 OLED 패널 제작이 불가능하여 Gen8 유리를 6분할한 증착 장비를 사용 할 수 밖에 없다. LG디스플레이의 WRGB OLED는 백색광과 칼라필터로서 픽셀을 제조하기 때문에 fine metal mask가 필요 없어 Gen8 원장에서도 OLED 패널 제작이 가능하다. 경쟁업체인 LG디스플레이가 Gen8 증착 장비 한대를 사용하고 있는 것과 비교하면 산술적으로는 6대의 증착 장비가 필요한 것이다. 증착 장비 증대는 당연히 투자비 상승을 수반하기 때문에 패널 제조 원가가 LG디스플레이에 비해 높을 수 밖에 없다.

삼성디스플레이는 TFT 제조 비용에서도 LG 디스플레이에 비해 상대적으로 경쟁력이 낮다. 삼성디스플레이가 사용하는 LTPS-TFT 공정은 8~9장의 mask 공정이 필요하나, LG디스플레이는 4~5장이 소요되는 oxide TFT를 사용하고 있다. 따라서 LCD 라인을 OLED 라인으로 개조할 때 투자비를 최소화 할 수 있는 장점이 있다. 삼성디스플레이가 기존 LCD 라인을 OLED 라인으로 개조하기 위해서는 LTPS-TFT 제조에 막대한 자금을 투입해야 한다. 삼성디스플레이가 기존 200K LCD 공장을 OLED 라인으로 개조하면 capa 역시 90K 정도로 줄어드나, LG디스플레이는 capa 손실 없이 200K 규모를 유지할 수 있다. 기존 LCD 라인을 개조하여 OLED를 생산 할 경우 LG디스플레이는 추가 공장 건설이 필요 없지만, 삼성디스플레이는 산술적으로 동일한 규모의 공장을 더 지어야 한다.

Encapsulation 기술에서도 LG디스플레이가 유리하다. LG디스플레이는 hybrid encapsulation 기술을 사용하고 있다. OLED 소자 제작 완료 후 2~3층의 passivation막을 형성하여 방습 구조를 만든 후 점착 필름이 라미네이션 된 metal foil을 passivation 막 상부에 합착하여 OLED 패널 제작을 완료한다. 삼성디스플레이가 2013년에 양산한 TV용 OLED 패널 역시 hybrid encapsulation 구조를 사용하였다. 차이점은 상부 기판이 유리였다. 그러나 LG디스플레이가 encapsulation 기술을 도용하였다고 주장하여 현재는 dam & fill 방식의 hybrid encapsulation 기술을 개발하고 있다. 삼성디스플레이의 hybrid encapsulation 기술인 dam & fill 방식은 소자 상부에 passivation 막을 형성하는 것은 LG디스플레이와 동일하나 그 이후 패널 외각에 유기물로써 형성된 dam에 ODF(one drop filling) 방식으로 경화제를 도포한 후 유리 기판을 합착하고 경화하는 공정을 사용한다. Dam 제조가 PDL(pixel define layer) 공정과 동시에 진행되면 좋으나 일반적으로 PDL층은 TFT 상부에 형성되어 있고 dam 구조는 패널 외각에 형성되어 있어 단차가 발생할 수 있어 상부 기판 합착에 어려움이 발생할 수 있다. 더욱이 dam의 높이가 PDL 보다 낮으면 최근 TV 트랜드인 curved design 구현에 불리하다. 따라서 dam 형성 공정을 passivation 완료 후 수행하게 되면 추가적인 mask 공정이 필요하여 추가 장비 투자로 인한 코스트 상승을 유발하게 된다. 삼성디스플레이의 encapsulation 공정은 연속적으로 진행되나 LG디스플레이의 공정은 경화 필름을 metal foil에 부착한 후 양품만을 골라 합착 공정으로 보낼 수 있어 상대적으로 수율 관리에도 유리하다. 더욱이 LG디스플레이는 상부 기판으로써 metal foil을 사용하고 있어 curved design 구현과 패널에서 방출되는 열을 제거하기에도 유리하다. Dam & fill 방식은 액상 경화형 레진을 미리 충진한 후 상부 기판을 합착하기 때문에 수십 um 두께의 metal foil 합착 보다는 수백 um 두께의 유리 기판을 사용하는 것이 보다 공정에 적절하다. 이 경우에는 metal foil을 사용할 수 없어 추가적인 방열 재료가 요구된다. Encapsulation 공정에서도 LG디스플레이 기술이 양산성이 우수하며 제조 비용을 줄일 수 있는 장점이 있다.

결론적으로 삼성디스플레이가 TV용 OLED 패널 사업에 다시 들어가기 위해서는 기존에 개발한 LTPS-TFT 공정과 RGB OLED, dam & fill encapsulation 기술 보다는 LG디스플레이가 사용하고 있는 oxide TFT 구조와 WRGB OLED 구조, 점착 필름을 사용하는 lamination 방식의 encapsulation 구조를 사용하는 것이 사업에 유리하다.

삼성디스플레이는 대형 OLED 패널 사업에 재 도전하기 위해 기존 대면적 OLED팀을 삼성디스플레이의 OLED 최고 전문가인 김성철 부사장이 이끄는 연구소 산하 조직으로 재배치하였다. OLED 패널 제조 기술 방향에 대해서는 아직 공식적인 논평이 없지만 OLED TV 사업이 성공하기 위해서는 LG디스플레이와 동일한 기술을 사용하는 것이 바람직하다.

삼성디스플레이는 다년간의 OLED 패널 양산 경험과 수천명의 우수한 OLED 엔지니어를 확보하고 있어 리소스 차원에서는 LG디스플레이 보다 유리하다.

남은 것은 특허와 의사 결정이다.

 

 

[Finetech Japan 2015] Mobile Display up to 700 ppi. How about OLED?

/in /by

At Finetech Japan 2015 (April 6-8), vice president of LG Display, Yoon Sooyoung, forecast the display resolution would evolve to 700ppi UHD for differentiation in technology. Japan Display’s CBO Yoshiyuki Tsukizaki also disclosed that a person can perceive up to 700ppi and estimated that mobile display resolution would therefore develop up to 700ppi.

 

Currently mobile display is being mass produced at QHD (approx. 500ppi), and UHD resolution is known to being actively developed for LCD. It is analyzed that UHD mobile OLED panel development will be a necessity in order to adapt to the trend toward high resolution. OLED is being mass produced in RGB pixel structure where FMM (fine metal mask) is applied. However, as FMM production technology is difficult, QHD AMOLED panel is being mass produced via pentile pixel structure rather than real RBG pixel structure. Therefore, technology for realization of mobile UHD resolution is expected to be a key issue in future.

 

For the mobile UHD AMOLED panel realization, securing shadow mask technology that allows for UHD resolution is important. In Finetech Japan 2015, V-Technology exhibited FHM (fine hybrid mask) technology that can produce 700ppi or higher resolution. V-Technology further revealed that “resolution of up to 738ppi can be produced using laser patterning technology after the formation of polyimide film on top of Ni mask”.

 

Additionally, another method is where white OLED + color filter is applied which uses color filter patterning technology. This is a comparatively easier method for producing high resolution, and JDI is aiming for mass production using WRGB structure. Chinese latecomers are also examining application of white OLED + color filter structure for high resolution AMOLED panel production.

 

The attention of the industry is now focused on how OLED will react and what solution will be generated facing LCD sector that is evolving toward UHD mobile display.

[Finetech Japan 2015] 모바일용 display, 700ppi까지 간다. OLED는?

/in /by


8일 개최된 Finetech Japan 2015 에서 LG Display 윤수영 상무의 keynotes 발표에 따르면 기술 차별화를 위해 Display 해상도는 700ppi UHD로 발전해 나갈 것으로 전망하였다. 또한, Japan Display의 CBO Yoshiyuki Tsukizaki 역시 700ppi까지 사람이 인지할 수 있는 해상도로 조사됐으며 이에 따라 모바일 display의 해상도가 700ppi까지 발전할 것으로 예상했다.

현재 모바일 display는 QHD(약 500ppi)의 수준으로 양산되고 있으며, LCD에서는 UHD에 대한 개발도 적극적으로 이루어지고 있는 것으로 알려져 있다. 모바일 OLED panel 또한 고해상도화로 향하는 기술 트랜드에 맞춰 UHD로의 개발이 필수적일 것으로 분석된다. OLED는 현재 FMM(fine metal mask)를 적용한 RGB pixel 구조로 양산되고 있다. 하지만 고정세의 FMM 제조 기술이 어렵기 때문에 현재는 real RGB 픽셀구조가 아닌 pentile 픽셀구조를 통해 QHD AMOLED panel이 양산되고 있다. 따라서 모바일 UHD해상도 구현을 위한 기술이 앞으로의 핵심 이슈가 될 것으로 전망된다. 모바일 UHD AMOLED panel 구현을 위해서는 UHD 해상도를 구현할 수 있는 shadow mask기술 확보가 중요하다.

이번 Finetech Japan 2015에서는 V-Technology에서 700ppi이상을 구현할 수 있는 FHM(fine hybrid mask)기술을 전시하였다. V-technology 관계자는 “Ni mask위에 polyimide film을 형성한 후 레이져로 patterning하는 기술로 738ppi까지 제조 가능하다”라고 하였다.

또 다른 방법으로는 상대적으로 고해상도 제조가 쉬운 color filter patterning 기술을 적용한 white OLED + color filter를 적용하는 방법으로 JDI에서는 WRGB 구조로서 양산을 목표로 하고 있다. 중국 후발업체들도 고해상도 AMOLED panel 제조를 위해 white OLED + color filter 구조 적용을 검토 중에 있다.

앞으로의 모바일용 display 시장에서 에서 UHD 해상도로 진화하는 LCD진영에 맞서 OLED가 어떤 해결책을 내놓을지 업계의 관심이 주목되고 있다.

[Finetech Japan 2015] The Third Display Revolution, to be Accomplished by OLED?

/in , /by

Speaking in a keynote session in Finetech Japan 2015 which opened on April 8, LG Display’s Vice President Yoon Sooyoung reported that “the first revolution in TV market was transformation to color from black and white, the second revolution was from CRT to flat panel display such as PDP and LCD, and the third revolution will be accomplished by OLED”.

 

Yoon also spoke that “until now the market was formed centering on investment by display companies, but in future the market will be created by differentiation and new application” and added “the key focus will be freedom in design and color quality such as rich color scheme” and that “OLED is the most suitable display for this”.

 

The differentiation mentioned by Yoon is OLED’s advantage in flexible and transparent realization as substrate can be formed using diverse materials compared to other displays. OLED is also superior in color gamut control through achievement of perfect black. Yoon emphasized the OLED is better suited for next generation display compared to LCD equipped with new technology; “LCD also achieved color gamut exceeding OLED through technology such as QD, but this is during full white, and in mid-range grayscale, color control is difficult in BLU driven LCD. However, OLED can perfectly express black using infinite contrast range and perfect color control is possible even in lower grayscale”.

 

On the basis of these advantages, LG Display is aiming for shipment of 600 thousand units of OLED panel for TV this year, and 1.4 million units in 2016, leading the launch of large area OLED TV market. LG Display is striving to bring the next generation of display market toward OLED by active mass production of plastic OLED panel. Samsung Display is estimated to further vitalize OLED market with their bold A3 mass production, and Chinese companies’ mass production will also do their part in OLED’s leadership formation in next generation display market.

[Finetech Japan 2015] 세 번째 Display 혁명, OLED가 이루나

/in /by

4월 8일 개막한 Finetech Japan 2015의 keynote session에서 LG Display의 윤수영 상무는 “TV 시장의 첫 번째 혁명은 흑백에서 컬러로 바뀐 것 이며, 두 번째 혁명은 CRT에서 PDP, LCD등의 flat panel display로 바뀐 것으로 세 번째 혁명은 OLED가 이룰 것” 이라고 발표하였다.

윤 상무는 “기존에는 display 업체들의 투자위주로 시장이 형성되었지만 앞으로는 차별화와 새로운 application을 통해 시장이 창출되고 디자인 자유도와 풍부한 색감 등의 화질이 핵심 포인트가 될 것”이라며, “여기에 가장 적합한 display는 OLED”라고 발표하였다.

윤 상무가 언급한 OLED의 차별화 포인트는 다른 display보다 기판을 다양한 소재로 변경이 용이하여 flexible과 transparent 구현에 유리하다는 것과 완벽한 black 표현을 통한 color gamut control이다.

특히 “LCD도 QD등의 기술을 통해 OLED를 넘어서는 color gamut을 구현하였지만 이것은 full white일 때 이며, 중간계조에서는 BLU로 구동하는 LCD로는 color control이 힘들다. 하지만 OLED는 무한대의 명암비로 black를 완벽하게 표현할 수 있어 중간계조 이하에서도 완벽하게 color control이 가능하다”라며 OLED가 신기술을 적용한 LCD보다 차세대 display로써 적합함을 강조하였다.

이러한 OLED의 장점을 바탕으로 LG Display는 올해 60만대, 내년 140만대의 TV용 OLED panel 출하를 목표로 하고 있어 대면적 OLED TV 시장을 개척하기 위해 앞장서고 있으며, plastic OLED panel의 본격적인 양산으로 차세대 display 시장을 OLED로서 이끌고 나가기 위해 적극적으로 나서고 있다. 또한 Samsung Display도 A3 line의 본격적인 양산을 시작으로 다시 한번 OLED 시장에 활력을 불어 넣을 것으로 예상되며, 중국업체들의 본격적인 양산 시작도 OLED가 차세대 display로서 주도권을 잡는데 한 몫을 할 것으로 예상된다.

A Place for OLED Unification

/in , /by

A place for OLED unification was held for Korea’s OLED industry which used to be divided. The two sides of Korean OLED industry, Samsung Display and LG Display, both attended the 1st OLED KOREA Conference, examining what lies ahead for OLED. This marks the beginning of future OLED display industry where worldwide OLED industry and Korean OLED industry are united.

 

The division within Korean OLED industry started when LG Display began to produce 55 inch OLED panel when Samsung was the only company that manufactured OLED panel. They each accused the other company of copying their technology and reported to the prosecution and thus the division was born. Last week, they both announced the end of legal disputes. However, although the trial for Samsung’s technology leakage has ended, the prosecution for LG’s technology is continuing. As this is a criminal case, the prosecution has to withdraw charges before it concludes.

 

In order to end the division within the Korean industry that began from Samsung and LG’s disputes, and to bring together worldwide OLED industry, UBI Research held the OLED KOREA Conference (April 2). 16 OLED experts from Korea, Japan, and China, including from Samsung Display and LG Display, forecast the future of OLED industry and discussed how OLED industry could succeed.

 

After the conference, approximately 40 industry-academic professionals attended VIP party and commented that the success of the conference was due to Samsung’s presence. Chang Hoon Lee who attended both OLED KOREA Conference and VIP party, and spoke with key speakers mentioned that Samsung will continue to be an axis for OLED industry and lead Korean and international OLED industry. The experts who attended the VIP event expressed hope that future OLED KOREA Conference would aid in the process of Korea, which is OLED device production oriented, becoming the mecca for OLED industry.

LG Display succeeded in developing world’s first flexible and transparent OLED.
LG Display announced the technological development of world’s first 18-inch flexible OLED and transparent OLED of same size, disclosing at the ‘national project workshop for transparent flexible display development’ to be held from July 10 till July 11.
It is considered that LG Display secured the foundation technology for developing a large screen transparent flexible display through the simultaneous development of flexible and transparent OLED this time.
The flexible OLED that LG Display developed is 18-inch in size with HD resolution (1200 X 810) nearly 1 mega pixel quality, and this is the largest OLED in the world, realizing the radius of curvature of 30R. This means it can be rolled up to a radius of 3cm with no operational complications and implies that it is possible to implement a large panel rollable TV over 50 inches in the future.
In order to realize maximum radius of curvature even on 18-inch screen, LG Display used Polymide film of polymer materials on a substrate that TFT and organic matters are deposited, reducing the thickness and increasing flexibility drastically.
Furthermore, this concurrently developed transparent OLED is of same size and resolution as flexible OLED and the transparency is 30% or higher realized by self-developed transparent pixel design technology. It is a radical increase of transparency, given that transparency of existing LCD based transparent display is about 10% or so.
LG Display maximized the degree of completion by lowering the haze caused by circuit element and film down to 2%.
The transparent flexible display is a national project of the future industry-leading technology development program promoted by the Ministry of Trade, Industry & Energy and the Korea Evaluation Institute of Industrial Technology, and LG Display is the leading participants of total 36 organizations of industries, academies, and institutes, aiming to develop a large 60-inch transparent and flexible display by 2017.
According to In-Byung Kang, Senior Vice President and Head of the R&D Center at LG Display, “Pioneered OLED TV market, LG Display is leading future applied technology of OLED,” and “Though there still are many challenges to be resolved, we are confident in developing transparent flexible display of over the 60-inch screen UHD (Ultra High Definition) screen with transparency of 40% and a curvature radius of 100R by 2017.”

By Choong Hoon Yi

 

The use of OLED is now expected to be extended from interior light and rear lamp to display of automobiles.

According to the display industry, LG Display (LGD) is negotiating with German automakers for plastic OLED panel supply. LGD ranked 4th in auto display market following Taiwanese Innolux, Japan Display and Sharp of Japan. It aims to take over the global market by reaching 1 billion dollars in sales based on the OLED display by 2016.

Most of major panel makers are currently focusing on leading the auto display market. At SID 2014, the major panel makers including Japan Display, Sharp, AUO and Tianma mainly showed displays for vehicles. LGD also reinforces targeting auto display market by integrating future technologies including transparent display. A fierce competition is ahead among major display companies.

The flexibility and durability; shock- and vibration-resistant, of the OLED as well as the fact that transparent display can be realized with it will accelerate its entry to the auto display market.

For auto rear lamp and interior light, the major OLED lighting panel makers including LG Chem. and Osram are developing the OLED and a new market is within the reach. If the OLED rapidly forms the auto display market, it will become a great cornerstone of the OLED industry along with mobile, TV and general lighting.140704_자동차산업

LG Display (LGD) actively competes in TV market by reducing OLED TV price.

A department head Byeonggyu Roh of LGD emphasized “cost reduction of LGD’s OLED panel should be carried out across all processes and continued” and introduced its cost reduction strategy for the OLED panel for the 2nd Annual OLED Workshop held on 24th.

Key cost reduction strategy includes various ways such as investment cost reduction by rearranging the existing lines and modifying equipment; material cost reduction by optimizing the thickness of layers for TFT, the OLED and encapsulation; tact time improvement; and production efficiency increase by investing in M2 line. Also it was expected that soluble process will be the core technology for cost reduction in the future.

CEO of UBI Research, Choong Hoon Yi, said “LGD’s ultimate goal is to reduce the price by 1.1 times compare to LCD” and announced “cost down can be realized through reducing investment cost as 65” UHD OLED TV displayed at SID 2014 applied the existing co-planar to reduce from the previous 6mask to 4mask.”

LGD recently began supplying the OLED TV panel to China, and it plans to operate the M2 line in the latter half of this year. It also dropped the price of a 55” FHD curved OLED TV to $3,999 from the released price of $15,000 and a price war with the LCD TV is about to begin.

[SID 2014] Latecomers catching up aggressively

/in /by

AMOLED latecomers; BOE, AUO and Tianma are rapidly catching up the AMOLED development of Samsung Display (SDC) and LG Display (LGD) at SID 2014.

BOE expressed possibility of investing in TV following mobiles by displaying 55” FHD AMOLED panel. In terms of technology readiness level, it is incompatibly lower than panels of LGD and SDC though, it is considerably fast that it was developed in six months and produced in a pilot line in Hefei.

AUO showed that its AMOLED technology had reached at certain level by unveiling 5.7” WQHD (513ppi) ultra-high resolution AMOLED panel. More attention drew towards AUO’s panel because its production method is RGB+FMM as SDC uses and the high resolution is realized with real RGB strip type rather pentile. AUO also expressed its will on AMOLED business by showing 5” HD flexible AMOLED panel and 1.6” AMOLED panel for a smart watch.

Tianma also unveiled 5.5” HD AMOLED panel. Its performance lags behind the current AMOLED panel, but it ai    ms to supply middle-end and low-end panel targeting mass-production of 5.5” FHD AMOLED through continuous R&D.

Challenges of Chinese and Taiwanese makers become serious in the AMOLED market, where Korean makers, SDC and LGD, are dominant, and the latecomers are about to invest in the sector. Thus, it is expected that the AMOLED industry will constantly grow.
