JOLED raised 47 billion yen to spur solution process OLED business for automobiles.

JOLED, the world’s first to successfully commercialize solution process OLED products, announced that it had raised a total of 47 billion yen as a third-party capital increase.

According to JOLED, Denso will invest 30 billion yen, Toyota Tsusho 10 billion yen, Sumitomo chemical 5 billion yen and SCREEN Finetech Solutions 2 billion yen. JOLED is known to cooperate with Denso to develop automotive displays and Sumitomo chemical to develop OLED materials for solution process.

In particular, Denso has been mainly using TFT-LCD for automotive displays, but it is expected to lead the development for applying lightweight and easy-to-shape OLED to automobile interior through this investment.

It is expected that this funding will accelerate the establishment of production system for the mass-production of JOLED’s solution process OLED. JOLED announced on July 1 that it would set up a “JOLED Nomi Office” in Nomi-city, Ishikawa, and aim to operate in 2020.

Major production products are medium-sized (10 to 32-inch) solution process OLEDs that will be used for cars or high-end monitors. Also, Toshiaki Arai, chief technologist of JOLED announced that they would target the middle-sized OLED market with solution process OLED, at the 2018 OLED Korea conference hosted by UBI Research in March.


JOLED 470억엔 조달, 자동차용 solution process OLED 사업 박차 가한다.

세계 최초로 solution process OLED 제품화에 성공한 JOLED가 23일 제 3자 할당 증자로 총 470억엔을 조달했다고 발표했다.

JOLED에 따르면 Denso가 300억엔, Toyota Tsusho가 100억엔, Sumitomo chemical이 50억엔, SCREEN Finetech Solutions이 20억엔을 투자할 것이며, Denso와는 자동차용 디스플레이 개발을, Sumitomo chemical과는 solution process용 OLED 재료 개발에 협력 할 것으로 알려졌다.

특히 Denso는 그 동안 자동차용 디스플레이용으로 주로 TFT-LCD를 사용했으나, 이번 투자를 통해 가볍고 곡면화가 용이한 OLED를 자동차 내부에 적용하기 위한 개발에 앞장 설 것으로 기대를 모으고 있다.

이번 자금 조달을 통해 JOLED의 solution process OLED 양산을 위한 생산 체제 구축이 가속화 될 것으로 기대된다. JOLED는 7월 1일에 이시카와현 노미시에 ‘JOLED 노미 사업소’를 개설하고 2020년 가동을 목표로 하고 있다고 밝힌 바 있다.

주력 생산 제품은 자동차나 하이 엔드 모니터용 중형 (10~32 인치) solution process OLED로써, 지난 3월 유비리서치가 개최 한 2018 OLED Korea conference에서 Toshiaki Arai chief technologist는 solution process OLED로 중형 OLED 시장을 공략할 것을 밝히기도 했다.

Flexible, started to be used in the OLED lighting market

The trend toward flexible design is on the rise in the OLED lighting market, too.

At Light + Building 2018, not only LG Display but also OLEDWorks and Sumitomo Chemical exhibited flexible OLED lightings, highlighting their differentiations from LED lightings.

In particular, OLEDWorks and Sumitomo Chemical attracted a lot of attention from the audience by introducing their flexible OLED panels respectively.

OLED Works released a flexible OLED panel “Brite 3 FL300C” with thin glass. The specifications are 10,000 hours (life time) and 57 lm/W @ 8,300 cd/m2 or 50,000 hours and 63 lm/W @ 3,000 cd / m2.

Sumitomo Chemical’s flexible OLED panel was fabricated through solution process on a PI substrate, with the life time of about 20,000 hours and 50 lm/W @ 1,500 cd/m2 and is.

The two flexible OLED lighting panels introduced by the two companies, which are prototypes, are similar to the performance of LG Display’s flexible lighting OLED panel, which is currently in production, with 55 lm/W and life time of 30,000 hours. When these two companies start mass production of flexible OLEDs, it is expected to make a big change in the market of flexible OLED lighting panels.

Meanwhile, LG Display, the leader in the OLED lighting market, launched the OLED lighting brand “Luflex” last December. At Light + Building 2018, LG Display exhibited various designs of lightings that can be implemented with flexible OLED lighting panels, which attracted the biggest attention of the fair attendants. Six award-winning products of the LG OLED Design Competition 2017 were exhibited, and there were many comments that the lightings are distinguished from LED lightings by maximizing the advantages of flexible OLED lighting.

OLED lighting 시장에서도 flexible 본격화

OLED lighting 시장에서도 flexible 디자인으로의 추세가 본격화 되고 있다.

Light+Building 2018에서는 LG Display 뿐만 아니라 OLEDWorks와 Sumitomo Chemical에서도 flexible OLED lighting을 전시하며 LED 조명들과의 차별화를 부각시켰다.

특히 OLEDWorks와 Sumitomo Chemical은 flexible OLED panel을 최초로 공개해서 관람객들의 큰 이목을 끌었다.

OLED Works는 thin glass를 적용한 flexible OLED panel “Brite 3 FL300C”를 공개했다. 스펙은 1만시간과 57 lm/W@8,300 cd/m2 또는 5만시간과 63 lm/W@3,000 cd/m2 이다.

Sumitomo Chemical에서 공개한 flexible OLED panel은 PI 기판을 이용하고 solution process로 제작되었으며, 효율은 50 lm/W@1,500 cd/m2 수명은 약 2만시간 수준이다.

두 업체에서 공개한 flexible OLED lighting panel은 프로토타입으로 현재 양산을 진행중인 LG Display의 flexible lighting OLED panel의 성능인 55 lm/W, 3만시간과 비슷한 수준이다. 이 두 업체에서 flexible OLED 양산을 시작하게 된다면 flexible OLED lighting panel 시장에 큰 변화를 일으킬 것으로 기대된다.

한편 OLED lighting 시장에서 선두를 달리고 있는 LG Display는 지난해 12월 OLED lighting 브랜드인 “Luflex”를 런칭한 이 후 첫 전시회인 Light+Building 2018에서 flexible OLED lighting으로 구현할 수 있는 다양한 디자인의 조명을 전시하여 관람객 들의 큰 이목을 끌었다. LG OLED Design Competition 2017의 수상작 6종류가 전시되었으며 flexible OLED lighting의 장점을 극대화 한 디자인으로 LED 조명과의 차별화가 돋보였다는 평들이 주를 이루었다.

Solution Process OLED, Max. 40% Decrease in Component Material Cost Possible Compared to WRGB

According to 2017 Solution Process OLED Annual Report published by UBI Research, when solution process (ink-jet printing) is applied to large area OLED, it could reduce up to 40% of component material cost, and approximately more than 18% of production cost compared to WRGB process that uses evaporation method.


Solution process is a technology that can manufacture RGB pixel structure of large size OLED panel without cutting mother glass using Gen8 manufacturing equipment or larger.


UBI Research analyst Hyunjun Jang explained that the solution process applied OLED has a simpler panel structure with 5 layers compared to 20 layers of WRGB OLED. WRGB OLED process material usage efficiency is only at 40% but solution process application could increase this to over 90%. Jang added that the lack of color filter is a factor that could decrease panel production price by reducing development cost. Particularly, this can greatly reduce emitting materials usage which occupies much of materials cost and contribute considerably to the fall in production cost. Furthermore, he added that cost setting of soluble emitting material per gram will be an important factor in production cost decrease and emphasized that organic material usage greatly decreases when soluble emitting materials are used but must consider price increase due to solvent cost, production cost, and development cost.


Solution process technology continues to receive attention as a key technology that can lead popularization of large area OLED, and key AMOLED panel companies are carrying out development.


In terms of technology, solution process OLED has lower emitting efficiency and short lifetime as diverse solvent is added to existing evaporation materials to transform into ink leading to low purity. This has been an important issue for panel and material companies for past several years. To improve this, DuPont, Merck, Sumitomo Chemical and others have been actively developing soluble OLED emitting materials. Much like evaporation materials, blue materials showed particular difficulty in performance improvement. However, at present significant portion of technology development has been carried out and investigation shows approximately 80% of lifetime and efficacy of has been achieved compared to evaporation materials.


2017 Solution Process OLED Annual Report compared and analysed WRGB OLED and solution process OLED’s competitiveness in terms of process, materials, and cost. Key issues, soluble OLED emitting materials development status, key companies’ trend, and solution process OLED market are analysed from various perspectives.

Solution Process OLED, WRGB 보다 최대 40% 부품소재비용 절감 가능.

유비리서치에서 발간한 “2017 Solution Process OLED Annual Report”에 따르면 solution process(ink-jet printing)공정을 대면적 OLED에 적용시 현재 양산에 사용중인 증착방식을 적용한 WRGB 공정대비 최대 40%의 부품소재 비용, 약 18%이상의 제조원가 절감 가능성이 있는 것으로 분석했다.

Solution process는 대면적 OLED panel을 Gen8 이상의 장비에서 원장 분할 없이 RGB pixel 구조로 제조할 수 있는 기술이다.

유비리서치 장현준 선임연구원은 “Solution process가 적용된 OLED는 20 Layer 적층구조로 이루어진 WRGB OLED에 비해 5 Layer만으로 이루어져 패널 구조가 단순하다. WRGB OLED 공정은 발광재료 사용 효율이 약 40%에 불과한데 반해 Solution process 적용시 90% 이상으로 발광재료 사용 효율을 향상시킬 수 있다. 따라서 발광재료 사용량을 크게 감소시킬 수 있어 원가절감에 큰 기여를 할 것으로 기대된다. 또한 color filter를 사용하지 않는 것 또한 패널 제조 원가를 감소 시킬 수 있는 요인이다”라고 언급하였다. 이에 덧붙여 “ Soluble 발광재료 kg당 가격책정이 “원가절감”에 중요한 부분이 될 것이며, soluble 발광재료 사용시 유기재료 사용량은 크게 감소 하지만 solvent 비용과 제조비용, 개발비용으로 인한 가격상승 역시 고려해봐야 할 점”이라고 강조했다.

Solution Process 공정기술은 대면적 OLED의 대중화를 이끌 수 있는 핵심 기술로서 지속적으로 주목받고 있으며 주요 AMOLED panel 업체들 개발을 진행 중에 있다.

기술적인 관점에서 보면 solution process OLED는 기존 증착재료를 ink화 시키기 위해 다양한 solvent를 섞는다. 이때문에 증착재료보다 순도가 낮아 발광효율이 떨어지고 수명이 낮다. 이는 지난 몇 년간 panel 업체들과 재료업체들의 주요 과제였으며 이를 개선하기 위해 DuPont과 Merck, Sumitomo Chemical 등에서 적극적으로 soluble OLED 발광재료를 개발해왔다. 특히 증착재료와 마찬가지로 blue 재료의 성능개선에서 어려움을 겪어왔으나 현재는 상당부분의 기술 개발이 이루어져와 증착재료 대비 약 80% 수준의 수명과 효율을 확보한 것으로 나타났다.

이번에 발간된 2017 Solution Process OLED Annual Report에서는 WRGB OLED와 solution process OLED의 경쟁력을 공정, 재료, cost 측면에서 비교분석하였으며, 핵심이슈와 soluble OLED 발광재료 개발 현황과 주요 업체 동향, solution process OLED 시장을 다양한 관점에서 분석하였다.

UBI research publishes 2017 OLED lighting report : LG Display, ready to mass-produce OLED light panel, expecting OLED lighting market to grow fast

■ LG Display starts mass production of 5G OLED panel for lighting from the end of September

■ OLED lighting panel market is projected to grow from US$ 1.9billion in 2021 to US$ 5.8billion by 2025


LG Display will start mass production of 5G OLED light panels from the end of September, therefore attention is focused on whether the OLED lighting market is growing rapidly. According to LG Display, monthly production capacity is 15K, and it is to be increased to 90K later.


According to the ‘2017 OLED Lighting Annual Report’ published by UBI Research on August 8, the global OLED lighting panel market is expected to grow to about US$ 1.9 billion by 2021. Furthermore, it is projected to have a CAGR of 85% for the period 2017-2025, and form a market of US$ 5.8 billion in 2025.

Because OLED lighting is thin, light and flexible, it does not limit the installation space and has excellent design autonomy. In addition, OLED lighting is used for automotive, exhibition, and medical as well as general indoor lighting because it can create a comfortable atmosphere with little heat and flicker.


However, the market for OLED lighting has been slower than that of OLED display, which is widely applied to mobile devices and TVs. Osram focuses primarily on automotive OLED lighting, and Philips sold its OLED lighting division to OLEDWorks. Also, Japanese panel makers such as Sumitomo Chemical and Konica Minolta have developed OLED lighting for industrial and medical applications. Nevertheless, it seems to take time for OLED lighting to become eventually a large market.

With LG Display’s mass production of Gen5 OLED line, the price of OLED light panel is estimated to drop below US $ 10 (100 x 100 mm). The significant price competiveness might enable OLED panels to be applied to various areas such as automobile and display lighting as well as indoor lighting. Owing to this expectation, attention is focused on whether the OLED lighting market, showing signs of slow growth, can be materialized.

UBI Research predicted that LG Display would account for about 70% of the world’s lighting OLED panel market in 2017, and will continue to lead the OLED lighting panel market with a 50% market share in 2020.


Meanwhile, ‘2017 OLED Lighting Annual Report’ describes trends of next-generation lighting market, promising applications, cost analysis upon the investment of LG Display and forecast of OLED lighting market. Since it analyses particularly OLED lighting market, materials market, and equipment market forecasts for OLED lighting from various perspectives, it is expected to help the related companies identify the OLED lighting market.

[Lighting Japan 2016] What is the Key Issue of Solution OLED Materials?

In Lighting Japan 2016 (January 13-16) conference, Sumitomo Chemical and Merck revealed recently developed soluble OLED materials performance results.


The soluble OLED materials efficiency published in this conference reached ≥ 65% of UDC’s evaporation materials; particularly, Sumitomo Chemical’s red achieved ≥ 85%, and green reached ≥ 88% of UDC’s evaporation materials efficiency. Lifetime (LT 95) results were not as good as efficiency with red’s 25% and green’s approximately 40% (average).


Sumitomo Chemical and Merck both revealed that although in terms of efficiency the soluble materials almost caught up to evaporation materials, but lifetime requires further development.


Solution process is a method that allows for large area OLED panel production in RGB method using ≥ Gen8 manufacturing equipment. Key panel companies are actively carrying out research development, and the performance of soluble OLED material is considered the biggest issue. According to Solution Process OLED Report 2015, published by UBI Research, when solution process is applied the material cost can be approximately 40% reduced compared to the current evaporation process using large area OLED panel. The timing for the solution process application to mass production is expected to be decided depending on the development speed of soluble OLED materials.
