[Analyst Column] Watch issued for the promotion of QD-LED BLU LCD TV

December 30, 2014/in Analyst column, Focus on /by OLEDNET

Lately, the media, research institutes and stock firms are scrambling to release data on the marketability of QD-LCD TV which is the LCD TV applying the QD (quantum dot) materials to the LED backlight. In the strict sense, it is not a LCD technology but a backlight technology. The QD-LCD BLU (backlight unit) can be divided into the three types; one is applying the QD material directly to the LED chip, another is arranging it in front of the LED chip; and lastly it is placing it in between LCD and Light Guide Plate after filming by inserting the QD materials to the barrier film.

The QD-LED BLU is being recognized as a LCD TV technology that can compete with the OLED TV as it has a merit to improve the color reproducibility up to about 12 percent compared to the existing LED BLU. Until now, the LCD TV manufacturers take the notion of resolution as a major marketing means to compete with other products like PDP. And it was the same with the OLED case. However, the Apple iPhone highlighted the resolution as the biggest difference with the Galaxy S of Samsung Electronics but Samsung Electronics counter attacked with the color reproducibility as overcoming the resolution issue with the pentile technology, ranking the first in the market share. The LCD TV part, presenting the 4K and 8K TVs continuously, expected that the OLED TV won’t be able to catch up but LG Display is planning to come into the market from 2015 as developing the 4K OLED panel in the 55-inch with the oxide TFT and WRGB OLED technologies.

Given that the superiority of the OLED panel’s picture quality over that of LCD was verified through Samsung Electronics’ Galaxy S and LG Electronics’ OLED TV, the best way to defense for the companies with no available OLED TV to sell is the early release of QD-LED BLU LCD TV with the improved color reproducibility.

The products applying new technologies have been well received in the market. The problem is that promoting the QD-LED BLU LCD TV to the extent of highlighting excessively may cause the distortion of a market or capital. For instance, the domestic stock firms are indeed reporting that the QD-LED BLU LCD TV as a highly eco-friendly product with an efficient energy consumption. But it is known that the brightness of the QD-LED BLU LD TV is 30 percent less than the existing LED BLU LCD TV. If the brightness decreases, it requires more LED chip and more driving modules as well, raising the production cost. Moreover, it emits more heat in proportion to the added amount of LED chips, increasing the corresponding cost for heat dissipation.

It is expected that the application of the QD-LED BLU will be limited to the premium products as there are numerous factors causing the increase of the production cost in varied channels. Though it is true that the QD-LED BLU can provide better picture quality than the LCD TV, it must be clarified that it is not the product surpassing the LCD TV.

And the careful attention of various media in using the name ‘QD TV’ is needed in that it might confuse general customers. The QD technology is also a very fascinating and appealing technology for the OLED developers. They are already developing the OLED panel using the QD materials and the blue elements in the field of OLED panel manufacturing technology. Then, this OLED TV eventually becomes the QD TV. Accordingly, it must be noted that any reports written without the clear understanding of QD may cause a considerable social repercussion in the display market.

[Analyst Column] QD-LED BLU LCD TV 띄우기 주의보

December 24, 2014/in 미분류 /by oled

최근 언론과 리서치 기관, 증권사 등에서 앞 다퉈 QD-LCD TV 시장성에 대해 자료를 내고 있다. QD-LCD TV는 LED backlight에 QD(quantum dot) 재료를 도포한 방식의 LCD TV이다. 엄밀하게 말하면 LCD 기술이 아니고 backlight 기술이다. QD-LCD BLU(backlight unit)는 일반적으로 3종류로 분류할 수 있다. LED chip에 직접 QD 물질을 도포하는 방식과 LED chip 앞 단에 배치하는 방식, 마지막으로 QD 물질을 barrier film에 삽입하여 필름화한 후 LCD와 도광판 사이에 두는 방식이 있다.

QD-LED BLU는 기존 LED BLU에 비해 색재현성을 약 120%까지 향상 시킬 수 있는 장점이 있어 OLED TV와 경쟁할 수 있는 LCD TV 기술로 인정 받고 있다. 이제까지 LCD TV를 제조하는 기업들이 PDP 등의 제품과 경쟁하기 위해서 항상 해상도를 주요 마케팅 수단으로 삼아 왔다. 물론 OLED에 대해서도 마찬가지였다. 그러나 Apple iPhone이 삼성전자 Galaxy S와 경쟁하며 해상도를 가장 큰 차별점으로 부각시켰으나 삼성전자는 pentile 기술로서 해상도를 극복하고 오히려 색재현성으로 역공하여 시장 점유율 1위로 등극했다. LCD TV 진영은 OLED TV가 나오자 4K와 8K TV를 연이어 전시하며 OLED가 따라오지 못할 것으로 예상했으나 LG디스플레이가 oxide TFT와 WRGB OLED 기술로서 이미 55인치에서도 4K OLED 패널을 개발하여 2015년부터 시판에 들어간다.

OLED 패널 화질이 LCD에 비해 월등하다는 것은 이미 삼성전자 Galaxy S와 LG전자 OLED TV로서확인 되었기 때문에 OLED TV를 판매 할 수 없는 기업들로서는 최선의 방어가 색재현성을 향상 시킨 QD-LED BLU LCD TV 조기 출시뿐이다.

새로운 기술이 적용되는 제품이 나오는 만큼 시장 반응도 뜨겁다. 문제는 QD-LED BLU LCD TV를 띄우는 것은 좋으나 지나친 강조는 시장과 자금을 왜곡 시킨다. 실제로 국내 증권사 보고서에서 QD-LED BLU LCD TV는 소비전력이 매우 우수한 친환경 제품인 것으로 보고하고 있다. 그러나 QD-LED BLU LD TV는 휘도가 기존 LED BLU LCD TV에 비해 약 30% 낮은 것으로 알려져 있다. 휘도가 줄면 그 만큼 LED chip을 증가 시켜야 하고 이로 인해 구동용 모듈도 증가하여 원가가 상승 한다. 또한 LED chip이 늘어난 만큼 발열이 증가하여 이에 상응하는 방열 비용이 증가하게 된다.

QD-LED BLU는 기존 LED BLU에 비해 색재현성이 좋아지나 다양한 경로로 원가가 상승하는 요인이 발생하여 프리미엄 제품에 한정될 것으로 판단된다. QD-LED BLU가 LCD TV에 보다 좋은 화질을 제공할 수 있는 것은 사실이지만 LCD TV를 넘어가는 제품이 아님은 분명히 해야 한다.

또한 각종 언론에서는 일반 소비자를 현혹시킬 수 있는 ‘QD TV’라는 명칭사용 대해 주의할 필요가 있다. OLED를 개발하는 기업들에게 있어서도 QD 기술은 매우 매력적이다. OLED 패널 제조 기술에서 blue 소자와 함께 QD 물질을 사용한 OLED 패널을 이미 개발하고 있다. 그렇게 되면 이 OLED TV도 QD TV가 되고 만다. QD에 대한 확실한 이해 없이 작성한 보도가 디스플레이 시장에 큰 파장을 일으킬 수 있음을 명심해야 할 것이다.

Samsung Display, to break through crisis with diversification of OLED customer!

December 22, 2014/in 미분류 /by OLEDNET

Samsung Display is speeding up to be post-Samsung Electronics. The world’s sole OLED panel that Samsung Display manufactures is applied to most of the products by Samsung Electronics’ IM Division. Samsung Display expected to expand the OLED panel market as building the A2 line additionally in 2013 but the Smartphone Galaxy S5 did not measure up to the expectations resulting gradual decrease of factory operation rate a long with the sales.

The diversification of customers is required at this moment in the Samsung Display’s AMOLED panel industry which heavily relies on Samsung Electronics. And the result of those efforts begins to appear in the tablet PC area. In the last month, Dell revealed the tablet PC Venue 8 7000 using the Samsung Display’s 8-inch AMOLED panel (refer to the OLEDNET article posted on November 4), and now Fujitu released the tablet PC ARROW Tab F-03G with 10.5-inch AMOLED panel. (http://www.fmworld.net/product/phone/f-03g/info.html#heading02). Fujitsu is emphasizing the excellent picture quality of the tablet PC with AMOLED panel compared to the product made of LCD.

It has been only half a year since the OLED was applied to the tablet PC and yet, it is anticipated to be applied by a wide range of industries from next year given that global set companies begin to use OLED.

삼성디스플레이, OLED 패널 고객 다변화로 위기 돌파한다!

December 19, 2014/in 미분류 /by oled

삼성디스플레이의 탈 삼성전자가 가속화되고 있다. 삼성디스플레이가 생산하는 세계 유일OLED 패널들은 대부분이 삼성전자 IM 사업부의 제품에 들어가고 있다. 삼성디스플레이는 2013년에 A2 라인을 증설하고 OLED 패널 시장 확대를 기대하였지만 삼성전자 스마트폰 갤럭시 S5가 시장에서 기대치에 미치지 못해 삼성디스플레이는 공장 가동율 하락과 함께 매출이 감소하고 있다.

삼성디스플레이는 삼성전자에 의존하고 있는 AMOLED 패널 사업에서 고객 다변화가 필요한 시점이다. 최근 삼성디스플레이의 노력이 tablet PC에서 조금씩 효과가 나타나고 있다. 지난달에는 Dell에서 삼성디스플레이의 8인치 AMOLED 패널을 사용한 tablet PC Venue 8 7000을 시장에 선보였으며(OLEDNET 11월 4일 기사 참조) 이번에는 Fujitsu가 삼성디스플레이 10.5인치AMOLED 패널을 사용한 tablet PC ARROW Tab F-03G를 출시했다. (http://www.fmworld.net/product/phone/f-03g/info.html#heading02). Fujitsu는 AMOLED 패널을 사용한 tablet PC의 화질이 LCD로 만든 제품보다 월등히 우수함을 강조하고 있다.

OLED가 tablet PC에 적용된 지 반년 정도 지났지만 삼성전자를 비롯하여 해외 세트 업체들도 사용하기 시작하여 내년에는 보다 다양한 회사에서도 사용이 있을 것으로 기대된다.

LG Display, strategic partnership for OLED business with Japanese firm Idemitsu Kosan

December 16, 2014/in 미분류 /by OLEDNET

LG Display (CEO Sang-beom Han, 韓相範 / www.lgdisplay.com) and OLED materials firm Idemitsu Kosan (CEO 月岡隆, Takashi Tsukioka, hereinafter “Idemitsu”) entered into the agreement on the 11^th about the ‘mutual cooperation concerning OLED technology and related patent license’ to further strengthen their competitiveness in the OLED industry.

In 1997, Idemitsu developed what was then the world’s brightest blue light organic emitting material for OLED and since then, every effort has been made to develop high-tech OLED materials and diverse device technologies based on its own molecular design and organic synthesis technologies. Consequently, Idemitsu Kosan, the original OLED material technology firm of a top global level possesses numerous major patents in relation to the OLED technology.

Through this strategic partnership, LG Display will be accessible to the excellent OLED materials and device structures of the Idemitsu Kosan which will lead to consolidate the research, product development and production of the OLED for TV and flexible OLED, and this eventually will accelerate the expansion of OLED market. By providing high performance OLED materials to the LG Display and collaborating in terms of technology development and commercialization, Idemitsu Kosan is expected to secure leading global clients in the display field.

The industry prospects that the two companies have made a chance to perform sound leadership by maximizing the synergy in the OLED business through this partnership.

Sang-deok Yeo, president of LG Display OLED Business unit said that, “Through the latest partnership, LG Display is to gain momentum to create OLED TV market on the basis of the OLED related patents of Idemitsu Kosan as well as accelerate the developments of flexible and transparent OLEDs” and added that “This win-win collaborative relationship is expected to have a huge synergy effect on OLED business for both companies.”

OLED TV, becomes the Quantum Dot TV just by placing a dot in the name?

December 16, 2014/in Market /by OLEDNET

Though they are a part of sales gimmick, extremely deluding names are emerging.

For OLED TV, the technology name “OLED” makes it easier for a consumer to recognize the differences of TVs precisely as it uses the OLED panel which is a spontaneous emission method employed to realize brightness and color. In the beginning of last year, LG Electronics and Samsung Electronics made it clear that it is not LCD TV by literally using the term ‘OLED TV’ for the TVs manufactured using OLED panel. But for LED TV, it should be named as LCD TV adopting LED BLU. The LED TV is the one that controls light only with LED.

The name LED TV was a dangerous concept allowing for that it is safe to deceive general customers to sell products. This concern reoccurs for the LCD TV employing the quantum dot technology. As the LCD TV adopting the quantum dot technology emerges as a new rising star of the TV market, the TV set producers are planning to ship the products under the names of QD TV, QLED TV, or Q Dot TV. While they are naming the LCD product as if it is a new TV made only with the quantum dot while in reality, the quantum dot technology is added to the LED backlight to improve the color reproducibility and power consumption.

The worst name is “QLED TV” which was created just by putting a dot in the OLED TV. It is assumed to be the combination of the terms LED TV and quantum dot. But it is very similar to the name ‘OLED TV’ that commonly recognized as the next generation TV to the extent of confusing as OLED TV.

In the TV market that becomes more and more competitive as time passes, the differentiation strategy is crucial to make a distinction with other companies. However, this immoral and disgraceful trick of playing with consumers with naming must be stopped. Like an automobile company gets a considerable penalty for selling a car with false mileage, the strict sanctions must be imposed upon TV manufacturers using names to deceive customers.

OLED TV에 점 하나 찍으면 Quantum Dot TV되나?

December 14, 2014/in 미분류 /by oled

상술도 좋지만 소비자를 극도로 현혹하는 이름이 출현한다.

OLED TV는 자발광 방식인 OLED 패널을 사용하여 휘도와 색, 칼라를 구현하기 때문에“OLED”라는 기술명이 TV에 사용되어도 소비자가 정확히 TV의 차이점을 인지할 수 있다. 작년 초에 LG전자와 삼성전자는 OLED 패널로 만든 TV에 OLED TV 이름을 사용하여 LCD TV가 아님을 분명히 했다. 하지만 LED TV는 LED BLU 채택 LCD TV라고 이름해야 정확하다. LED만으로 빛을 컨트롤 해야지 LED TV라고 사용할 수 있다.

LED TV라는 이름은 팔기 위해서는 일반 소비자들을 속여도 무방하다는 매우 위험한 발상이었다.이러한 우려가 quantum dot 기술을 채용한 LCD TV에서 다시 발생하고 있다. TV 시장의 새로운 기대주로서 quantum dot 기술을 적용한 LCD TV가 떠오르자 TV 세트 메이커들이 앞다퉈QD TV 또는 QLED TV, Q Dot TV 등으로 이름 지어 제품을 출하할 예정이다. LED backlight에quantum dot 기술이 추가되어 색 재현성과 소비전력이 향상된 것에 불과한 LCD 제품을 마치quantum dot 만으로 만든 새로운 TV인 것처럼 이름을 짓고 있다.

최악의 이름은 OLED TV에 점 하나 찍어 만든 “QLED TV”이다. LED TV라는 이름과 quantum dot을 혼합한 이름일 것으로 추정된다. 차세대 TV임을 자타가 공인하는 ‘OLED TV”와 이름이 흡사하다 못해 OLED TV로 착각하게 하는 이름이다.

날이 갈수록 치열해 지는 TV 시장에서 타사 제품과 차별화되는 전략은 누구나 필요하다. 하지만 이름만으로 소비자를 농간하는 비도덕적인 추태는 더 이상 자행되지 말아야 한다. 자동차 회사가 연비를 속여 차를 팔았을 때 매우 엄한 페널티를 물게 하는 것처럼 소비자를 속이는 이름을 사용하는 TV 제조 회사에는 엄격히 제재를 가해야 한다.

If the 600ppi Soluble process OLED is to be possible?

December 12, 2014/in 미분류 /by OLEDNET

As a company producing ink-jet equipment for the soluble process OLED, Seiko Epson has already developed the ink-jet head which could realize up to 360ppi by arranging the 180ppi nozzles in 2 rows. Given that the resolution of the evaporation method RGB OLED is still in the 260ppi as a real RGB, it is a significantly useful technology in the development of high-resolution display.

Seiko Epson developed the technology to maintain total amount of ink in a fixed rate per pixel with the ink volume control and multiple nozzles, and also holds the technology to apply emissive layer evenly on the entire surface of HTL by making the surface of HTL and the contact angle of separation equal. In addition, the productions of the bottom emission OLED as well as the top emission OLED were succeeded in ink-jet. Top emission is possible when the HIL thin layer is applied extremely evenly using special combination of ink as the thickness of HIL layer influences greatly on the optical character.

Seiko Epson is planning to develop the 600ppi ink-jet head that arranges the 400ppi nozzles in two rows in order to develop the equipment producing hyper-resolution soluble process OLED. It is anticipated if it is possible to manufacture a hyper-resolution OLED of 600ppi, it will be the moment to replace LCD in the mobile display area for it could easily resolve the greatest weakness of OLED which is high-resolution issue.

[Analyst Column] G Watch R and Galaxy Gear S Structures and Disassembling Video

December 11, 2014/in Analyst column /by OLEDNET

G Watch R and Galaxy Gear S by LG Electronics and Samsung Electronics respectively were disassembled to see their structures. First of all, much of the internal and external design concepts were quite similar. Claiming to be the classical sports type watch, the G Watch R is a smart watch emphasizing the sense of watch rather than its diverse smart functions while Galaxy Gear S was produced with a design of fashion watch. From dismantling both products, it was revealed that for G Watch R, the plastic OLED display which corresponds to the plate of watch is attached to the glass of the watch as shown by removing the back plate by unscrewing from the back side just like a regular watch and internal components, but for Galaxy Gear S, the flexible OLED panel was attached to the front side with adhesive so that the window detaches as applying heat to the front side.

In terms of the module design aspect including display, G Watch R shows dualised touch whereas Galaxy Gear S shows neatly unified look as FPCB. As the flexible OLED that Samsung Display is producing uses the touch screen of on-cell method, there is only one FPCB but for the plastic OLED of LG Display, it has the touch of add-on method, expected to have two FPCB to give signals.

The radiation design is critical in the smart watch as a variety of components are concentrated in it. In case of G Watch R, the sections for the plastic OLED and electronic components are divide with a radiation sheet in between. For Galaxy Gear S, there is a small radiation sheet in the plastic component which separates the metal Foil assumed to be the Cu film to reduce heat generated from the display in the back side of display (refer to the image above) and component.

600ppi Soluble process OLED가 가능해지면?

Seiko Epson은 soluble process OLED용 ink-jet 장비를 만들고 있는 기업으로서 180ppi 노즐을 2열로 배치하여 360ppi 해상도까지 실현 가능한 ink-jet head를 이미 개발하였다. 증착 방식 RGB OLED 해상도가 real로서는 아직 260ppi 수준에 머물고 있는 것에 비교하면 고해상도 디스플레이 개발에 매우 유용한 기술이다.

Seiko Epson은 잉크 볼륨 제어와 복수 노즐로서 화소 당 총 잉크량을 일정하게 유지할 수 있는 기술을 개발하였으며, HTL 표면과 격벽면 접촉각을 동등하게하여 HTL 표면 전체에 균일하게 발광층을 도포할 수 있는 기술도 가지고 있다. 또한 bottom emission OLED 제조와 함께 top emission OLED 제조도 ink-jet으로 성공하였다. Top emission은 HIL의 막 두께가 광학 특성에 큰 영향을 주기 때문에 특별히 조합한 잉크를 사용하여 매우 균일한 HIL 박막을 도포할 수 있어야 가능하다.

Seiko Epson은 초고해상도 soluble process OLED를 제조할 수 있는 장비를 개발하기 위해400ppi 노즐을 2열로 배치한 600ppi ink-jet head를 개발할 예정이다. 600ppi의 초고해상도OLED가 제조 가능해지면 OLED의 최고 단점인 고해상도를 문제를 가볍게 해결할 수 있어mobile display 영역에서 LCD를 대체할 수 있는 계기가 될 전망이다.

[Analyst Column] G Watch R과 Galaxy Gear S 구조와 분해 영상

December 10, 2014/in 미분류 /by oled

LG전자와 삼성전자에서 판매중인 G Watch R과 Galaxy S를 분해하여 구조를 살펴 보았다. 우선 양사의 내부 디자인은 외부 디자인 컨셉과 매우 일치하였다. G Watch R은 외형이 고전적인 스포츠 타입 시계를 표방한 smart watch로서 다양한 smart 기능 보다는 시계 본연의 느낌을 강조한 제품이며, Galaxy Gear S는 패션 시계 디자인으로 제작되었다.

양사 제품을 분해해 본 결과 G Watch R은 일반 시계와 유사하게 뒷면의 나사를 풀고 뒤 판을 제거한 내부 부품을 빼면 시계 판에 해당하는 plastic OLED 디스플레이가 시계 유리에 부착되어 있으나, Galaxy Gear S는 오히려 flexible OLED 패널이 부착된 앞 면이 접착제로 부착되어 있어 앞면이 열을 가하면 윈도우가 분리될 수 있게 설계 되어 있었다.

<LG전자 G Watch R>

<삼성전자 Galaxy Gear S>

디스플레이를 포함한 모듈 설계 부분에서 G Watch R은 디스플레이 touch가 이원화되어 있는 것으로 보이고 있으나, Galaxy Gear S는 FPCB로 일체화되어 깔끔하게 만들어져 있다. 삼성디스플레이가 생산하고 있는 flexible OLED는 on-cell 방식의 touch screen을 사용하고 있기 때문에 FPCB가 1개만 존재하며, LG디스플레이의 plastic OLED에는 add-on 방식의 touch가 부착되어 있어 신호를 주기 위한 FPCB가 2개 있는 것으로 예상된다.

<Gear S(좌)와 G Watch R(우)의 패널>

각종 부품들이 집적화되어 있는 smart watch에는 방열 설계가 중요한 요소이다. G Watch R에는 plastic OLED와 전자전기 부품들이 있는 구간이 나누어져 있으며 사이에는 방열 시트가 존재하고 있다. Galaxy Gear S는 디스플레이 후면(위 사진 참조)에 디스플레이에서 발생하는 열을 빼기 위한 Cu 필름으로 추정되는 메탈 호일과 부품 사이를 분리해주고 있는 플라스틱 부품에 소형 방열 시트가 존재하고 있다.

<Gear S(좌)와 G Watch R(우)의 모듈>

종합적으로 양사의 제품을 분해해서 보았을 때, G Watch R은 고전적인 시계 디자인과 함께 내부 구성 역시 시계 구성을 본 딴 것으로 나타났으나 Galaxy Gear S는 smart phone 시장의 강자답게 smart phone의 유전자를 물려 받은 fashionable한 기기인 것으로 분석된다.

Display for the Color Deficient Person, Vision Aid

November 28, 2014/in 미분류 /by OLEDNET

At the nation’s largest display exhibition IMID which was held in October at the KINTEX, Ilsan, the latest display products received great attentions including the Samsung Display’s curved UHD TV, Galaxy Note Edge curved edge display, etc.

Especially, the ‘Vision Aid’ function for the red-green color deficient person was noticeable above all technologies. It is a display of a new concept assisting red-green color deficient person to recognize precise colors. We had a chance to talk to the research and development personnel of Samsung Display and hear about the operation mechanism as well as the behind story.

<Vision Aid R&D Personnel>

■ Tell us about the context of developing the Vision Aid!

→ We literally were researching the technology for the future display. We are not concerned with improving the existing picture quality related issues such resolution, contrast range, etc. but with finding new technologies which will be needed in the future. The conclusion made after a long consideration is ‘to make humanistic display for humans.’ As starting from that perspective, numerous projects came into the sight for us to develop the commonly termed ‘Bio Display’. And the Vision Aid is part of the Samsung Display’s Bio Display.

■ Tell us the meaning and significance of this technology!

→ It is said that everything in the 21^st century is connected through the internet. It is not too much to say that one sees the world through a display of a smartphone, tablet, PC, etc. And there are over 3% of color deficient person in the general population of Korea. That is, at least 1.5 million people are not able to distinguish colors exactly. We believe this is very important to research the display that enables color deficient people to see precise images and videos in the era of internet.

This is not the first technology concerning the color deficient people. But previous technologies were primarily about increasing the color discrimination by changing the value of color like transforming the red into purple. Then, it becomes more difficult to recognize correct colors as it distorts the original color. The Vision Aid helps one to recognize color without any alteration or distortion of color.

■ Tell us more about the technological principles and methods!

→ The cone cells in the retina of the eye play a role of transmitting the detected lights to the optic nerves. There are three types of receptors for red, green and blue. The red-green color deficiency occurs as the functions of the receptors of red and green decrease. The degree of the cone cell function degradation determines the level of color deficiency. When it is impossible to distinguish red or green at all, one becomes red-green color blind.

The Vision Aid is a technology adjusting the red and green colors to appear more intense purposefully. For this purpose, the degree of color deficiency was digitized and classified to be applied as a color compensation technology and enhanced the completeness through the technology verification conducted in consultation with ophthalmologists.

■ What was the core element that enabled to realize this technology?

→ The Vision Aid is a technology possible due to the special quality of AMOLED that uses organic light emitting diodes. What you need to do is just control to emit stronger red and green colors. And it is possible to manage the degree of red and green colors depending on the level of color deficiency. However, there is a restriction in realizing it with LCD as it is structurally hard to control the light by pixel.

<‘Vision Aid’ display that was uncovered at IMID 2014>

■ How was the collaboration process with ophthalmologists for the development of Vision Aid?

→ Many ophthalmologists of considerable authorities advised on numerous aspect in the course of development. For the customers who choose to use our product, we are currently joint developing the intuitive evaluation methods appropriate for IT devices.

Saying that “Until now, there only was the test method for color deficient people but no particular treatment, so it would be a great help if it is developed”, a professor who has developed the test method for color deficiency gave us a lot of help and proposed diverse ideas. The display technology is equivalent to the field concerning the human vision and thus, the experience with ophthalmologists was helpful in developing other products.

■ Was there any episode in the process of development?

→ What was critical in the course of development was the hands on evaluation by the color deficient people but it was not easy to have testers. As it became known to the company that we are developing the technology for the color deficient people, many employees volunteered as a tester. One of them told us that he had to memorize the entire test sheet to pass the physical examination when it was hard to get a job. As those volunteer testers have experienced many discomforts due to the color deficiency, they were very much interested in the Vision Aid technology and willing to help us developing the product.

■ You all must have felt rewarded when developing this technology.

It is very reassuring to have many supporters who understand the importance of the bio display. It was a pleasant experience to realize a possibility for a new development of display as working with the professionals from the diverse fields such as ophthalmologists, psychiatrists, psychologists, etc. The biggest thrill is that this technology actually could be helpful for the people experiencing visual discomforts.

※ The color deficient person experience filter used in this video is to verify the Vision Aid function and there can be slight differences for each actual color deficient person.

China to start mass producing AMOLED from the end of this year

November 28, 2014/in 미분류 /by OLEDNET

Shenzhen Daily’s reporter Anna Zhao reported that Shanghai’s EverDisplay will begin to manufacture AMOLED panels starting the end of this year after the interview with Zhu Ketai, general manager of the company.

Zhu said that EverDisplay will increase production of a volume of high-quality AMOLED panels with high-definition and true color images, pointing out that although China’s mid- and low-end display screen market has been grown, the country still lacks a stake in the high-end product market with flagship brands.

Founded in October 2012, EverDisplay developed the 6-inch, VGA mono color AMOLED with 133ppi in January 2013. In December the same year, the company successfully developed the 5-inch HD full color AMOLED panel with 294ppi. With a line of the Gen-4.5 AMOLED products, the outfit aims to produce AMOLED panels used for smartphones, wearable devices, and automobiles and for the military purpose.

EverDisplay reportedly placed orders regarding two deposition systems respectively to Sunic System and Tokki in a bid to increase the manufacturing of AMOLED panels.

Solution-processed OLED to be commercialized in years

November 28, 2014/in Market /by 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

November 28, 2014/in Analyst column, Focus on /by 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.

[Analyst Column] 용액공정 OLED, 2016년부터 출시 전망

November 27, 2014/in 미분류 /by oled

2013년 파나소닉의 용액공정(Solution process) 4K OLED TV가 등장하고 AUO가 SID2014에서 잉크젯 프린팅 방식과 증착방식을 동시에 사용하는 하이브리드(hybrid) 공정을 이용한 65인치 FHD AMOLED 패널을 공개하면서 용액공정의 RGB 구조로 AMOLED 패널 양산이 가능함을 보여주었다.

26일 유비산업리서치가 발간한 Solution Process OLED Report에 따르면 현재까지 공정장비와 재료개발 수준을 고려했을 때 2016년부터 용액공정 AMOLED 패널이 출하될 것으로 전망하였다.

용액공정은 액체상태의 재료를 프린팅을 통해 OLED를 제작하는 공정이다. 기존에 사용되고 있는 증착공정은 증착 RGB 방식의 경우 재료 사용 효율이 약 10%로 높지 않으며, 공정이 복잡하고 대면적 기판 적용에 어려움이 있다.

용액공정의 경우, 재료 사용효율이 이론적으로 100%이기 때문에 패널 제조 비용을 줄일 수 있으며, 8세대 라인에서 까지 기판을 자르지 않고 RGB 방식으로 공정이 가능하다는 장점이 있다.

하지만, 현재까지는 증착재료에 대비하여 재료 특성이 낮고, 고해상도의 패널 제작이 어렵다는 점이 해결과제로 남아있었다.

유비산업리서치 관계자는 최근 프린팅 오차가 줄어들면서 300ppi까지 프린팅이 가능해짐에 따라 RGB 방식으로 8.4인치 FHD 패널에서부터 30인치 이상의 크기에서 8K 고해상도 패널 제조가 가능한 것으로 분석되었다고 전했다. 현재 판매되고 있는 태블릿PC용 OLED 패널은 펜타일 방식으로 제작되었기 때문에 약 262ppi의 해상도를 나타낸다. 용액공정 기술이 300ppi까지 가능해짐에 따라 용액공정으로 대면적 패널뿐만 아니라 태블릿용 RGB OLED 패널 양산이 가능해지게 된다.

<그림 : 용액공정 가능한 패널 범위>

발광재료 특성 또한 향상되었다. 현재까지 공개된 특성을 분석하였을 때 용액공정용 발광재료 중 red와 green의 효율은 증착재료와 근접한 수준까지 개발되었다. 특히 green의 경우 용액공정용 저분자 재료가 증착용 고분자재료보다 우수한 효율을 나타낸 것으로 분석되었다.

유비산업리서치 관계자는 “현재까지 용액공정용 재료와 공정장비 개발 수준을 고려해봤을 때2016년부터 용액공정으로 제작된 AMOLED 패널이 본격적으로 출하 될 것으로 전망되며, 패널 업체들의 라인상황과 투자여력, 기술상황을 고려하면 태블릿 PC용 AMOLED 패널이 우선적으로 출시될 것으로 예상된다.”고 전했다.

또한 2017년부터 용액공정용 재료가 경쟁력을 갖출 것으로 예상되어 2017년용액공정용AMOLED 패널 시장은 연평균 141%의 성장률로 3억 8천만달러의 시장을 형성할 것으로 전망하였다.

The grand achievement was made for the Korean researchers as the Organic Light Emitting Diodes (OLED) lighting technology that they have suggested for the first time in the world was chosen as the international standard by the International Electrotechnical Commission (IEC).

This accomplishment will promote domestic companies to enter into the OLED lighting field as Korea occupies more than 90% of the entire global market in case of AMOLED display using OLED.

The ETRI (Electronics Telecommunications Research Institute, President Heung Nam Kim) announced on the 11^th that Dr. Jo Du-hui from the Soft I/O Interface Research Lab conduced significantly to the international standard of 『Safety requirements for OLED panels used in general lighting』.

OLED lighting is drawing attention as a representative creative technology to lead the next generation lighting industry for it has eco-friendly properties like energy saving and, in addition, it is thin, lightweight, transparent and bendable.

Especially for OLED, it is advantageous in terms of industrial infrastructure utilization as Korea is dominating the global market of AMOLED display.

Therefore, the researchers are expecting to have higher international competitiveness than in any other lighting fields.

ETRI was carrying out the enactment of international standard as a pressing task along with the development of relevant technologies to build OLED lighting industry ecosystem.

It is because the standardization is critical to use and industrialize the OLED as a light source of numerous lighting fixtures.

Thus, the speedy preoccupancy of international standard by ETRI is to be the favorable condition in the Korean OLED lighting related industry.

In the course of legislating the international standard, the opinions and test results concluded in consultation with the domestic company were reflected on the standard.

Accordingly, the ETRI expects to create groundwork for the expansion of market in a short period of time by saving time and cost for domestic companies in industrializing and minimizing the confusion in entering into the market.

ETRI is planning to take the lead of the performance standard in relation to the efficiency and lifespan of OLED light source following the international standard regarding safety field.

Furthermore, it was said that the standard for the module will be carried forward additionally.

Supported by the Lighting Committee of Korea Agency for Technology and Standards, Dr. Jo Du-hui performed outstandingly as the chairperson of ‘OLED Lighting Working Group,’ which is IEC’s technical subcommittee for lighting fields since 2011.

The standard proposal for the ‘Safety requirements for OLED panels used in general lighting’ was submitted to IEC in November, 2011 for the first time and issued in September as the final decision was made after the three-year long discussions and revisions.

Every electronics must be certified through the safety test when importing and exporting. The international standard that Dr. Jo of ETRI accomplished is defining test methods and standard values for various electric/mechanical characteristics of OLED together with the labelling requirements for the safety certification.

The registration of international standard for OLED lighting is a remarkable success of obtaining Korea’s first international standard in the international standard organization of lighting field where advanced countries are taking the lead.

As stated by the UBI Research which is the professional OLED related market research media, the OLED lighting panel market is prospected to be about $ 4.7 billion in 2020 globally.

ETRI forecasts that there is growing possibility of Korea occupying the world’s OLED lighting market in advance on this occasion of the international standardization besides the fact that it is the OLED lighting industry of Korea which has the one and only mass production technology in the world.

Lee Jeong-ik, the executive director of Soft I/O Interface Research Lab said that, “This research result is expected to activate OLED lighting industry and contribute to establishment of the new ecosystem for the next generation lighting industry conform to creative economy scheme.”

ETRI performed a leading role in periodic technology developments together with international standardization tasks from the material/parts to the light source-lighting fixtures through the support by the Ministry of Science, ICT and Future Planning and the Ministry of Trade, Industry and Energy.

This accomplishment of standardization was facilitated through the ‘Development of Key Technology for Interactive Smart OLED Lighting’ project by the Ministry of Science, ICT and Future Planning.

Gen6이상의 라인에서 원장으로 RGB 패널을 제작할 수 있는 기술은 solution process(용액공정) OLED가 유일하다. 그 동안 이 기술의 단점으로 지목된 재료의 특성과 해상도가 향상되어solution process로 제작된 제품이 수년 이내에 생산될 전망이다.

Solution process 기존 기술로서는 해상도가 200ppi정도여서, 고해상도가 요구되는 스마트폰과 tablet PC에는 적용이 불가능 하였으나 최근에 300ppi까지 가능한 기술이 개발되어 고속성장의 가능성이 보이는 tablet PC용 제품까지 적용이 가능하게 되었다.

또한 4K는 물론 8K(7680×4320) TV용 패널까지 제작이 가능해진다. 65인치의8K(7680×4320)패널의 경우 약 140ppi해상도를 나타내게 된다. 200ppi 이상의 패널이 제작이 가능하다면 고해상도의 RGB OLED TV 패널 생산이 가능하게 되는 것이다.

최근 출시된 AMOLED panel을 적용한 10.5인치 패널의 경우 해상도가 287ppi이며, pentile구조로 제작된 것을 감안하면, RGB방식의 solution process 기술로서도 충분히 경쟁력 있는tablet PC용 패널을 제작할 수 있을 것으로 예상된다.

November 14, 2014/in Market /by OLEDNET

On the 6^th, Universal Display Corporation (UDC), the U.S panel company, announced on their website that the 3Q/2014 Performance Summary was released on 30^th October.

The sales for the third quarter of 2014 is $32.9 million similar to $32.8 million which was the 3Q sales in the previous year. It is analyzed that the rise by a small margin is because the royalties and license fees were increased from $1.5 million in the third quarter of the last year to $5.4 million. In addition, another result includes the decrease of materials sales by 9% from $30.3 million to $27.5 million. It is considered that it fell due to the poor host materials sales. The business profit is $6.1 million, increased $1.9 million from the same period a year earlier.

The sales by the third quarter of 2014 is $134.9 million, increased by 39% as compared to the corresponding period last year. Though there is little demand for materials as the OLED industry is still in the preliminary stage, the UDC indicated on the report that there are variables to come. For that reason, the sales for this year is expected to be between $183 million and $185 million.

색약자를 위한 디스플레이, Vision Aid

November 14, 2014/in 미분류 /by oled

지난 10월 일산 킨텍스에서 열린 국내 최대 디스플레이 전시회 IMID에서는 삼성디스플레이의 커브드 UHD TV, 갤럭시 노트엣지용 커브드엣지 디스플레이 등 최신 디스플레이 제품들이 높은 관심을 받았는데요.

특히 눈길을 끌었던 기술은 적록색약자를 위한 ‘Vision Aid’ 기능이었습니다. ‘Vision Aid’는 적색과 녹색에 대한 색구별이 약한 사람들이 정확한 색상을 인지할 수 있도록 도와주는 신개념 디스플레이인데요. 이를 개발한 삼성디스플레이의 연구 개발 담당자들을 만나 작동 원리와 개발 과정의 뒷이야기를 들어보았습니다.

<Vision Aid의 연구 개발 담당자들>

■ Vision Aid를 개발하게 된 배경을 설명해주세요!

→ 저희는 말 그대로 미래디스플레이 기술을 연구하고 있습니다. 해상도, 명암비 등 기존 화질 개선과 관련된 연구과제가 아니라 미래에 필요한 새로운 기술을 찾는 것이 저희 역할인데요. 오랜 고민 끝에 나온 결론은 ‘인간을 위한, 인간적인 디스플레이’를 만들자는 것이었습니다. 그런 관점에서 우리가 개발해야 할 기술을 검토해 보니 상당히 많은 과제가 도출되었고, 이를 통칭하여 ‘Bio Display’로 부르고 연구를 진행하고 있습니다. Vision Aid는 삼성디스플레이의 Bio Display 기술 중 하나입니다.

■ 이 기술이 갖는 의미와 중요성에 대해 설명해주세요!

→ 21세기는 모든 것이 인터넷으로 연결되는 시대라고 합니다. 요즘은 스마트폰이나 태블릿, PC 등의 디스플레이를 통해 세상을 바라본다고 해도 지나친 표현이 아닌데요. 우리나라만 해도 색약자가 전 인구의 3%를 넘는다고 합니다. 그러니까 적어도 150만명 이상이 색을 정확하게 구분하지 못하고 있다는 것인데요. 이처럼 인터넷 시대에 색약자들이 정확한 영상과 이미지를 볼 수 있도록 하는 디스플레이를 연구하는 것은 대단히 중요한 일이라고 생각합니다.

이전에도 색약자를 위한 기술이 없었던 것은 아닙니다. 그러나 대부분 붉은색을 보라색으로 변환하는 것처럼 색상값을 크게 바꿔 색 변별성만 높이는 것이었습니다. 그렇게 하면 본래의 색을 다른 색으로 왜곡시켜 오히려 정확한 색상 인지를 방해할 수 있는데요. Vision Aid는 색상의 변형이나 왜곡 없이 색을 인지하는 데 도움을 줍니다.

■ 기술 원리와 기술방식에 대해 좀 더 자세히 알려주세요!

→ 눈의 망막에 있는 원추세포는 빛을 감지해 시신경에 전달하는 역할을 하는데요. 원추세포는 각각 적색, 녹색, 청색을 인식하는 적추체, 녹추체, 청추체의 3가지가 있습니다. 적록색약은 원추세포 중 적추체와 녹추체의 기능이 저하되었기 때문에 발생하는 것인데요. 원추세포 기능 저하의 정도에 따라 색약의 수준이 결정됩니다. 적색이나 녹색 구분이 아예 불가능한 경우는 적록색맹이 되는 것이고요.

Vision Aid는 적록색약자를 위해 적색과 녹색을 의도적으로 강하게 보이도록 보정하는 기술인데요. 이를 위해 색약의 수준을 수치화하여 단계로 분류한 뒤 색보정기술로 활용하였으며, 안과 전문의들의 조언을 들어 기술을 검증하고 완성도를 높였습니다.

■ 이런 기술구현이 가능했던 핵심 요인은 무엇인가요?

→ Vision Aid는 자체발광하는 유기물질을 사용하는 AMOLED의 특성 때문에 가능한 기술입니다. 적색과 녹색의 화소만 더 강한 빛을 내도록 제어하면 되는 것이니까요. 색약 정도에 따라서 적색과 녹색의 강도도 조절하는 것이 가능하고요. 반면 LCD는 구조적으로 픽셀 단위로 빛의 색을 제어하는 것이 어렵기 때문에 구현하는 데 한계가 있습니다.

< 2014 IMID에 공개되었던 ‘Vision Aid’ 디스플레이>

■ Vision Aid 개발을 위해 안과 전문의들과는 어떻게 협력하셨나요?

→ 색약 연구에 권위가 있는 안과 전문 교수님들이 개발 과정에서 많은 자문을 해주셨는데요. 현재는 저희 제품을 채택하는 고객사를 위해 IT기기에 적합한 직관적 평가법도 공동개발하고 있습니다.

색약자 검사법을 개발하신 교수님 한 분은 “그동안 색각 이상자를 위한 검사법만 있고, 치료법이 따로 없어 안타까웠는데, 이런 기능이 개발된다면 정말 큰 도움이 될 것 같다”며 매우 적극적으로 도와주시고 다양한 아이디어도 제안하셨습니다. 디스플레이 기술은 곧 인간의 시각을 다루는 분야라고 하겠는데요, 안과 전문 교수님들과 협력한 경험이 또 다른 제품을 개발하는 데 많은 도움이 될 것 같습니다.

■ 개발 과정 중 있었던 에피소드가 있다면?

→ Vision Aid의 개발 과정에서 꼭 필요한 것이 색약자 분들의 직접 평가였습니다. 테스터를 모집하기가 쉽지 않았는데요. 색약자를 위한 기술을 개발한다는 것이 회사 내에 알려지면서 많은 사우들이 자원해서 테스터로 나셔주셨습니다. 그 중 한 분은 취업이 어려웠던 시절 신체검사 때 색약검사를 통과하기 위해 검사표를 통째로 다 외웠다고 귀띔해주셨는데요. 테스터로 자원하신 분들 모두 색약으로 불편을 많이 겪었기에 Vision Aid 기술에 관심을 갖고 흔쾌히 제품 개발에 도움을 주셨답니다.

■ 이 기술을 개발하면서 보람을 많이 느끼셨을 것 같습니다.

바이오 디스플레이의 중요성을 깨닫고 응원해주시는 분들이 많아서 큰 힘이 되고 있습니다. 안과, 정신과의사, 심리학자 등 다양한 분야의 전문가와 논의하고 협의하면서 디스플레이의 새로운 발전 가능성을 알게 되어 기쁘기도 했습니다. 특히 시각적으로 불편함을 느끼는 분들에게 실제 도움을 줄 수 있는 기술을 개발하는 것이라 더욱 보람이 큽니다.

※ 본 영상에서 사용한 색약자 체험필터는 Vision Aid 기능 확인을 위한 것으로

실제 색약자들에 따라 약간의 차이가 있을 수 있습니다.

LGD, Plastic OLED Technology Announcement

November 13, 2014/in Technology /by OLEDNET

LG Display (LGD) is promoting actively as unveiling the plastic OLED technology applied to its own G Watch R.

It is published under the title ‘The New Advancement in Display technology: LG Display’s Plastic OLED’ on the LGD’s U.S Newsroom (http://lgdnewsroom.com/) and the contents are as follows.

The New Advancement in Display technology: LG Display’s Plastic OLED

What is Plastic OLED?

Plastic OLED is an OLED that is made out of plastic substrate. There are 4 very special key technologies applied to this OLED.

1) Plastic, not glass

LG Display has shattered the common belief that plastic cannot stand high temperatures, and developed plastic substrate (PI or polyimide) that remains stable under high temperatures and has chemical stability. Moreover, due to the development of the coating process of large format PI, it has become possible to manufacture PI film, which has enabled the plastic curving technology and the technology to eliminate unnecessary bubbles and foreign substances.

2) LTPS(Low Temperature Poly Silicon) TFT(Thin Film Transistor) technology

One of POLED’s important features is that it can have thin bezel, since the fast electron mobility technology made the integration of different parts to be possible.

3) Flexible Encapsulation Technology to protect OLED elements

With the technology to manufacture inorganic film that prevents water and organic film that prevents alien substances, plastic OLED guarantees the stability of OLED elements.

4) Elimination of Carrier Glass using laser, and adhesionof Back Plate Film

The display surface is relatively clean and neat, as it prevents foreign substance from permeating the surface, by using Laser Source Uniformity technology, alien substance/crack prevention process technology, and flat-panel Back Plate Film and Film Lamination technology.

Why Plastic OLED?

1)Compared to currently existing displays, Plastic OLED has simpler structure. As it can be seen from the diagram below, LCD is composed of many layers of boards, while OLED’s structure is very simple.

2)While glass displays are prone to breakage, Plastic OLED, which is film based, is flexible to be curved to a certain angle, and it does not break easily.

3)Compared to LCD and glass OLED displays, Plastic OLED is thinner and lighter.

The future of Plastic OLED

As Plastic OLED can be applied to curved displays that are bent to a certain curvature, it can be used in various ways, including electronic goods, such as mobile phones, monitors, and TV, as well as cars, wearable devices, and items for interior design.

Other than its design, Plastic OLED is valuable in terms of portability and durability as well. Hence, it seems that Plastic OLED will play an important role in people’s everyday lives in the future.

The Plastic OLED’s potential is very promising. LG Display is devoting its energy and resources to respond quickly to fast growing market and consumers’ needs in order to develop Plastic OLED to become the key OLED application technology in the future.

Development of the high efficiency solution processed fluorescent organic light-emitting device

November 11, 2014/in Technology /by OLEDNET

Korean researchers have developed the highly efficient florescent organic light-emitting device which enables to enhance the efficiency more than three times and is receiving much attention as the next generation display.

This research by the Prof. Jun Yeob Lee, the Ph.D. candidate/researcher Yong Joo Cho (the 1^st author) and the Prof. Kyoung Soo Yook from the Department of Polymer Science and Engineering at Dankook University was supported by the Mid-career Researcher Program funded by the Ministry of Science, ICT and Future Planning and the National Research Foundation of Korea as well as the General Researcher Program funded by the Minister of Education and the National Research Foundation of Korea, and the research results were published on the Advanced Materials which is the international journal covering materials science on the 15^th October. (Paper Title: High Efficiency in a Solution-Processed Thermally Activated Delayed-Fluorescence Device Using a Delayed-Fluorescence Emitting Material with Improved Solubility)

Using the solution processing, it is expected to ease and simplify the process of producing the organic light-emitting device as the large area compared to the existing vacuum deposition plating.

However the problem is that when a device is produced through the solution processing using the existing fluorescent emitting material, the efficiency (external quantum efficiency) is only 5%. This is much less than the 20% which is the efficiency when produced by the vacuum deposition plating process.

The research team developed the high efficiency fluorescent organic light-emitting device, improved three times more than the previous fluorescent device for the solution processing. Compared to the existing structure, a solubility was increased by introducing the alkyl group as a substituent. Furthermore, the Donor-Acceptor Structure was employed to realize high efficiency by inducing delayed fluorescence phenomenon.

It is anticipated to advance the commercialization of a large scale organic light-emitting device for the enlargement of a future display.

The decrease of efficiency issue was resolved by making the surface film coating of a device smooth through the development of a new fluorescent light-emitting material which is soluble in organic solvents.

And introducing the strong Donor – Acceptor structure, it was possible to improve the efficiency as drawing delayed fluorescence phenomenon. The Donor – Acceptor structure refers to a monomer composed of an entity that donates electrons to another compound and that accepts electrons transferred from another compound.

Professor Lee revealed that “The following research will be continued to commercialize the solution processed fluorescent organic light-emitting device by developing a new material to improve not only the efficiency but also the lifespan of a device and a device structure appropriate for a solution processing.”

LGD, Plastic OLED 기술 공개

November 10, 2014/in 미분류 /by oled

LG Display(이하 LGD)가 자사의 G Watch R에 적용된 plastic OLED기술을 공개하며 적극적인 홍보에 나서고 있다.

LGD의 미국 뉴스룸(http://lgdnewsroom.com/)에 ‘The New Advancement in Display technology: LG Display’s Plastic OLED’이라는 이름으로 게재되어 있으며 그에 대한 내용은 아래와 같다.

The New Advancement in Display technology: LG Display’s Plastic OLED

What is Plastic OLED?

Plastic OLED is an OLED that is made out of plastic substrate. There are 4 very special key technologies applied to this OLED.

1) Plastic, not glass

LG Display has shattered the common belief that plastic cannot stand high temperatures, and developed plastic substrate (PI or polyimide) that remains stable under high temperatures and has chemical stability. Moreover, due to the development of the coating process of large format PI, it has become possible to manufacture PI film, which has enabled the plastic curving technology and the technology to eliminate unnecessary bubbles and foreign substances.

2) LTPS(Low Temperature Poly Silicon) TFT(Thin Film Transistor) technology

One of POLED’s important features is that it can have thin bezel, since the fast electron mobility technology made the integration of different parts to be possible.

3) Flexible Encapsulation Technology to protect OLED elements

With the technology to manufacture inorganic film that prevents water and organic film that prevents alien substances, plastic OLED guarantees the stability of OLED elements.

4) Elimination of Carrier Glass using laser, and adhesion of Back Plate Film

The display surface is relatively clean and neat, as it prevents foreign substance from permeating the surface, by using Laser Source Uniformity technology, alien substance/crack prevention process technology, and flat-panel Back Plate Film and Film Lamination technology.

Why Plastic OLED?

1) Compared to currently existing displays, Plastic OLED has simpler structure. As it can be seen from the diagram below, LCD is composed of many layers of boards, while OLED’s structure is very simple.

2)While glass displays are prone to breakage, Plastic OLED, which is film based, is flexible to be curved to a certain angle, and it does not break easily.

3)Compared to LCD and glass OLED displays, Plastic OLED is thinner and lighter.

The future of Plastic OLED

As Plastic OLED can be applied to curved displays that are bent to a certain curvature, it can be used in various ways, including electronic goods, such as mobile phones, monitors, and TV, as well as cars, wearable devices, and items for interior design.

Other than its design, Plastic OLED is valuable in terms of portability and durability as well. Hence, it seems that Plastic OLED will play an important role in people’s everyday lives in the future.

The Plastic OLED’s potential is very promising. LG Display is devoting its energy and resources to respond quickly to fast growing market and consumers’ needs in order to develop Plastic OLED to become the key OLED application technology in the future.
