2014년 11월 28일/0 코멘트/카테고리: 미분류 /작성자: OLEDNET

A solution-processable OLED technology is the one of its kinds that can RGB panels by using mother glasses for Gen 6 or later OLED panels. After some improvements are made to the properties of materials and definition, solution-processed OLED products will be manufactures in years to come.

So far, the existing solution process technology with a resolution of 200ppi could not be applied to smartphones and tablet PCs requiring a higher definition. With the development of the new technology that can feature a resolution of up to 300ppi, however, the solution process can become applied to tablet PCs with the potential for rapid growth.

In addition, it is possible that solution process technology is utilized to manufacture ultra HD 4K and even 8K (7680×4320) TV panels. The 65-inch 8K (7680×4320) panels are expected to feature a resolution of approximately 140 ppi. The manufacturing of panels that can produce an image of 200 ppi or higher will lead to the production of high-definition RGB LED TV panels.

Given that the 10.5-inch panels using the recently released AMOLED panels have a resolution of 287 ppi and use a Pentile layout, tablet PC panels with a RGB layout will be manufactured by using the solution process technology.

[Analyst Column] Solution Process OLED to be released from 2016

2014년 11월 28일/0 코멘트/카테고리: 미분류 /작성자: OLEDNET

The possibility to mass produce AMOLED panel in RGB structure by solution process was confirmed after the appearance of the solution process 4K OLED TV by Panasonic in 2013 and as AUO unveils the 65-inch FHD AMOLED panel at SID 2104 which uses hybrid process of employing inkjet printing method and deposition method simultaneously.

According to the Solution Process OLED Report 2014 issued by the UBI Research on the 26^th, it is expected to release AMOLED panel by solution process by 2016 considering the stages of the process equipment and materials developments up to now.

The solution process is producing OLED by printing the material of liquid condition. The efficiency of the material usage in case of the existing RGB deposition method is as low as about 10%, requiring complicated processes and it is difficult to apply to the large area substrate.

The efficiency is theoretically 100% for the solution process, resulting cost saving and even the process of RGB method without cutting the substrate at the 8^thgeneration line is possible.

However, there are remaining issues to be resolved as the material property is low compared to the deposition material and it is unavailable to produce high resolution panel.

The personnel from the UBI Research reported that the analysis shows the probability to produce from 8.4-inch FHD panel to 8K high resolution panel over 30 inches in RGB method for it is possible to print up to 300ppi as the printing error reduces. The present OLED panel for tablet PC has a resolution of about 262ppi because it was produced in PenTile method. Now, the large area panel as well as the RGB OLED panel for tablet PC are mass produces as a result of the solution process allowing up to 300ppi.

[Figure : The scope of panel available for the solution peocess]

Also the property of emitting material was improved. Assumed from the analysis of properties announced so far, the efficiencies of red and green among other emitting materials for the solution process are developed close to the deposition material. Especially for the green, the small molecular material for the solution process appears to be more efficient than the polymer material for the deposition.

“Considering the development level of the material and process equipment for the solution process, the AMOLED panel produced in the solution process will be released actively from 2016, and in view of the current line conditions of panel companies, the investment ability, and technical situations, it is expected to produce the AMOLED panel for the tablet PC at first” said the personnel from the UBI Research.

In addition, the AMOLED panel market for the solution process will be the size of $380 million with the average annual growth rate of 141% by 2017 as the material for the solution process is anticipated to have the full competitiveness by the same year.

Flexible AMOLED의 위력

2014년 11월 3일/0 코멘트/카테고리: 미분류 /작성자: oled

Flexible AMOLED가 왜 필요한가에 대해서는 많은 사람들이 의문을 가지고 있다. 이유는 flexible AMOLED는 휘어져야 한다 또는 말릴 수 있어야 한다고 생각하기 때문이며 이러한 용도의 제품이 필요한지에 대해서는 아직 모르고 있기 때문이다. 이것은 오래 전부터 flexible display를 개발하던 기업들이 꿈의 디스플레이로서 소개한 concept이기 때문이다.

Flexible display에 대해 가장 큰 오해는 말수 있는 display이다. 분명히 말하자면 현재의 기술로서는 말면 안 된다. 이유는 set가 이러한 디스플레이를 아직 수용할 수 없다. 디스플레이를 말게 되면 set는 기본적으로 원통형이 필요하다. 이 경우에는 set를 구성하고 있는 각종 부품이 모두 원통의 case에 들어가야 하기 때문에 구동 시에 발생하는 열을 방출할 수 없다. 또한 현재의 battery 기술로서는 소형의 원통에서 장시간 디스플레이와 각종 전기전자 부품을 구동할 수 있는 성능을 가진 제품이 개발되어 있지 않으며, 향후로도 막대한 시간이 걸릴 수 밖에 없다.

휘어질 수 있는 디스플레이는 현재의 기술로서도 가능하다. 또한 접을 수 있는 디스플레이도 가능하다. 이 경우에set는 현재와 마찬가지의 평편한 구조를 그대로 채택할 수 있기 때문이다. Flexible AMOLED의 가장 큰 이점은 깨어지지 않는 특징과 얇기 때문에 set의 design을 자유롭게 할 수 있는 점이다. 특히 현재의 mobile AMOLED에서 가장 큰 취약점은 frit glass를 사용하고 있어 외부 충격에 쉽게 파손 될 수 있다. BLU를 사용하는 TFT-LCD 보다도 자체 두께는 얇지만 보강 구조 때문에 두께를 줄이는 데는 한계가 있다. 그러나 flexible AMOLED는 필름으로 구성되어 있어 외부 충격에는 매우 강할 수 밖에 없다. 따라서 display의 크기가 클수록 flexible AMOLED의 가치는 더욱 커지게 된다.

Frit glass를 사용하는 mobile AMOLED 제조 한계는 약 7인치로 알려져 있다. 10인치 이상의 tablet PC용에는 사용할 수 없다는 것이 정설이다. 현재 mobile 기기는 smart phone에서 phablet로 이미 옮겨지고 있으며, 향후 거대 시장은tablet PC 시장이 될 것임은 자명하다. 이러한 시장에서 성공할 수 있는 또 하나의 AMOLED는 깨어지지 않는 flexible AMOLED이다. Flexible AMOLED가 tablet PC에 사용되면 초박형의 가벼운 tablet PC를 만들 수 있어, 소비자가 사용시 떨어뜨려도 깨어지지 않기 때문에 TFT-LCD를 사용하는 제품에 비하면 내구성이 월등히 높아질 수 있는 핵심 부품이 될 수 있다. 또한 매우 얇기 때문에 set를 design하는 메이커로서는 form factor를 자유롭게 design할 수 있어 grip감이 우수한 제품을 만들 수 있다. TFT-LCD와 대등한 두께로 가져 갈 시에는 고용량의 battery를 사용할 수 있어 사용 편이성이 매우 높아진다.

따라서 flexible AMOLED는 향후 tablet PC 시장을 지배할 수 있는 핵심 display가 될 수 있기 때문에 mobile display로서는 최고로 중요한 시장을 형성할 수 있는 cash cow로 성장할 수 있다.

[Analyst Column]For OLED Panel Late Starters, Securing High-Resolution Mask is Crucial

2014년 10월 21일/0 코멘트/카테고리: 미분류 /작성자: OLEDNET

The Chinese display companies like Visionox, Tianma, etc. are preparing the development and commercialization of OLED panel with BOE at the head. To keep up with the present leading company, Samsung Display, these second movers must be equipped with both product quality and reasonable price.

As the front runners of OLED panel, Samsung Display is maintaining the exclusive market for rigid type OLED which is made of a glass, and LG Display is producing the plastic (flexible) OLED panel using PI substrate for mobile devices.

The OLED panel is produced in QD resolution as a mobile device changes to adopt a high-resolution, but it is not a real resolution but uses a pentile method. For Samsung Display and LG Display are the two leading companies of the OLED industry, the supply chain is very firmly structured. So the relatively latecomers in this industry have difficulties in getting good materials and components from the suppliers who have intimate relationship with these two companies from the materials to equipment and components providers.

Furthermore, the established companies are managing and controlling the ecology of the industries to exclude the rival companies, preventing suppliers from providing products to the competing companies or late starters. Due to these strategies, the new comers are unable to secure sufficient resources for the development.

A typical component is a shadow mask which is critical for high-resolution. Known as a fine metal mask, this mask is an essential element to produce a high-resolution OLED of RGB structure and the shadow mask made of about a 40um thin plate to produce the high-resolution OLED which is more than 300 ppi but it is hard to find suppliers for the late comers.

BOE is seriously reviewing the matter of developing the OLED of WRGB structure to solve the shadow mask issue. The WRGB OLED does not require a fine metal mask as it uses the emitting materials in layers. The WRGB OLED creates the white light and realizes colors through the color filter.

Tianma is in the process of developing the slot type mask splitting the shadow mask.

KITECH, Developed the world’s first refining technology for organic light-emitting material using ILs for OLED TV

2014년 7월 28일/0 코멘트/카테고리: 미분류 /작성자: OLEDNET

Dr. Taewon Kim’s team of photovoltaic energy convergence research group of Korean Institute of Industrial Technology (KITECH, President Yong-Soo Lee) developed an original technology to refine organic light-emitting materials in bulk for fine OLED TV at low price.

Dr. Kim’s team established a new concept for the refining technology by using Ionic Liquids (ILs), and it can solve issues of high cost·low yield rate arisen in production of the organic light-emitting material for the OLED TV.

Ionic Liquids are liquids that only consist of positive and negative ions at room temperature and stays in liquid form at high vacuum (~100℃) with almost no volatility. Recently, ILs became a future clean solvent in green chemistry field with a strength of good solubility for high molecular substance and a feature of metal salts.

Until now, ‘sublimation refining method’ has been used to get high purify organic light-emitting material by utilizing the difference of sublimation points between vaporization and solidification of a material. However, cons of this method are low yield rate and very high production cost because it is impossible to realize complete auto and continuous process.

To address this issue, Dr. Kim’s team started developing the large scale refining technology for the organic light-emitting materials at low cost since 2011 and applied for original patent in December, 2012. Their effort on verifying the possibility of the technology’s application produced this result in 19 months.

The key of the result is the application of the high purity refining technology on the organic light-emitting material for the OLED TV by focusing on the non-volatile feature of ILs at high vacuum·high temperature.

This technology uses a principle of separating impurities in the order of vaporizing the organic light-emitting material in a vacuum chamber; dissolving it in a liquid filter of ionic liquid; and recrystallizing supersaturated material in the liquid. It enables to get 99.95% of high purity organic light-emitting material through one refining process.

It is a completely new concept of large scale refining method based on the non-volatility characteristic of ionic liquid at high vacuum·high temperature.

The team is credited with the success of new technology development which can overcome the cons of the existing sublimation refining method including refinery yield rate, automation and continuous process of equipment, and efficiency of mass production. It is also expected to bring a huge cost reduction effect by recycling; collect and reprocess during refinery process, of the expensive but non-volatile ionic liquid.

According to “2014 OLED Emitting Material Annual Report Market Forecast (~2020)” by a professional OLED market research firm, UBI Research, the OLED emitting material market is expected to grow to 1.3 trillion won in 2017 from 2014 estimation of 543 billion won. Forecasted annual growth rate is over 30% and experts see that the growth will be much larger if large size display market including the AMOLED TV expends in full-scale.

Dr. Taewon Kim, said, “this technology increased the yield rate and decreased the production cost by more than 50%. And an ultimate goal is to reduce the current price by one tenth” and “technology development is in progress with companies.” He also said, “the success is a game changer with enormous potential to turn the OLED TV market-to-explosively grow” and “based on the low-cost and large scale refining original technology, domestic businesses will largely contribute to preoccupy the global market of forward-backward industry regarding the OLED TV.”

The team currently applied 16 cases for patent with related process․equipment technology in and out of the country and plans active technology transfer to related businesses.

Ctimes, a Chinese medium, reported that a Chinese smart phone maker, Gionee, will introduce an ultra-thin smart phone modeled GN9005.

GN9005 used AMOLED panel and is 0.55mm thinner than 5.55mm of the previous model, which was introduced as Elife S5.5 last February.

It is noticeable that 4.8” HD AMOLED panel is applied which is smaller than the 5” FHD Super AMOLED applied to the previous Elife S5.5. In general, the AMOLED panels produced by Samsung Display are named super AMOLED. However, no particular name for the AMOLED panel applied to GN9005 and its low performance indicate that the panel is highly likely to be supplied by AUO.

It is known that AUO has started supply to a Chinese maker from last June but any specifics on the maker has not been revealed.

A Chinese smart phone maker, BBK, drew attention with 5.75mm VIVO X3 after the launch of 6.18mm Ascend P6 by Huawei last year. Followed by launching, Gionee introduced the 5.55mm Elife S5.5 in February and will launch 5mm GN9005 and that fierce competition will begin soon in the ultra-thin smartphone market in China.

UDC describes that the technology reduces the resolution by 33% compare to RGB FMM, but the increase of the blue region will increase the overall lifespan and decrease the power consumption of the display. It also announced that it could lower the production cost by reducing tact time and improving yield rate.

Like UDC, the industry develops various technologies to reduce the yield rate and cost of the AMOLED, and further continuous development of the AMOLED is expected.

OLED lighting, replacing LED is in the not too distant future

2014년 6월 11일/0 코멘트/카테고리: 미분류 /작성자: OLEDNET

At SID2014, it was proved that OLED lighting has competitiveness in terms of efficiency and can compete with LED for the general lighting.

Konica Minolta developed 131lm/W OLED lighting panel last March. It also released an OLED lighting panel with efficacy of 139lm/W at the SID 2014 and drew more attention. Panasonic also presented on OLED, and drew more attention unveiling a prototype in Author interview.

Considering that the efficacy of currently commercialized LED lighting is about 80~130lm/W, it is analyzed that the fruitful result at the SID 2014 showed the potential of the OLED lighting becoming the general lighting instead of the LED lighting.

The most concerned issues of the OLED lighting are lifetime and cost. For the general lighting, 40,000hr, which the OLED panel makers target, is estimated enough considering replace period of the lighting, but the issue is the cost. Compared to the LED, the OLED lighting is expensive and currently forms a high-end lighting market. However, it is inevitable to down the cost for entering the general lighting market. Although LG Chem. announced a price reduction to 200$/Klm from 600$/Klm, investment of the OLED lighting makers in mass-production is vital to reform the general lighting market with the OLED lighting.

The OLED lighting panel has reached the level equal to the LED lighting. Now is the time that the OLED lighting panel companies make a turning point and can leap again by investing as they did with display.

did with display.

[인터뷰] 국제 학술대회 유치 김영관 ICELㆍ4 조직위원장

2003년 8월 28일/0 코멘트/카테고리: 미분류 /작성자: oled

한국에서 이같은 대규모 국제 유기EL 학술대회가 개최된다는 것은 한국 디스플레이산업의 국제적인 위상을 재확인시켜주는 것이자, 관련산업이 향후 큰 전환점을 맞게될 것임을 의미하는 것입니다”제4회 국제 유기EL 학술대회를 국내에 유치한 김영관 ICEL―4 조직위원장(홍익대 교수)은 이번 학술대회의 의미를 이같이 설명하고, 이를 계기로 국내 유기EL 기술 개발 및 인식의 전환이 필요하다고 강조했다.김 위원장은 최근 발표된 차세대 성장산업에서도 디스플레이 산업이 중요하게 부각된 만큼, 현재 TFT LCD나 PDP의 경쟁력을 기반으로 차세대 디스플레이인 유기EL을 적극 육성하려는 노력과 정책적 뒷받침이 필요하다고 주장했다.

그는 “세계 최고의 경쟁력을 갖고 있는 TFT LCD, PDP의 뒤를 이어 10년 후 한국의 디스플레이 산업의 중심 축이 될 수 있는 것이 유기EL”이라며, “이번 국제학술대회가 이같은 인식의 변화를 주도하는 계기가 되기를 바란다”고 밝혔다.

김 위원장은 현재 일본은 D램과 TFT LCD 등의 주도권을 한국에 빼앗긴 이후 차세대 핵심 육성 분야로 유기EL을 정하고 이 분야에 대한 연구개발에 집중하고 있으며, 중국과 대만 등도 후발주자로서 TFT LCD나 PDP보다는 유기EL에 대한 연구에 박차를 가하고 있다고 전했다.

글로벌 경쟁이 치열해지고 있는 디스플레이산업 분야에서 유기EL 등 차세대 디스플레이 연구 개발 및 투자를 게을리 한다면, 당분간은 한국이 TFT LCD와 PDP 등을 통해 디스플레이 분야의 선두를 유지할 수 있을지 모르지만, 그 이후엔 다시 일본이나 대만 등에 주도권을 넘겨줄 수밖에 없는 상황이 도래할 수 있다고 경고했다.

따라서 반도체와 디스플레이 등의 분야에서 힘들게 확보한 한국의 세계적인 경쟁력을 사장시키지 않기 위해선 정부와 학계, 산업계 등이 힘을 모아 유기EL 등 차세대 디스플레이를 적극적으로 육성해야 한다고 덧붙였다.

그는 이런 측면에서 이번 국제 유기EL 학술대회가 세계적인 기술 흐름을 보여주는 장으로서 뿐만 아니라, 유기EL에 대한 일반적인 인식을 제고하는 계기가 됐으면 한다는 바람을 피력했다.
