At the 28th FINETECH JAPAN held in Makuhari Messe, Japan during December 5-7, 2018, Hiroyuki Hara, manager of Denso said that OLED will be used as future automotive displays due to their various advantages.

Hara refers to the large screen including the touch panel as the latest trend of automobile display, and now LCD is mainly used. However, OLED is expected to be used more and more in automobiles as the automotive electronics makers and drivers demand high-quality displays.

Saying that key elements in automotive displays are high contrast ratio, wide viewing angle, design autonomy, light weight, low reflection and reliability, Hara emphasized that the display that can satisfy all of these key elements is OLED. In addition, the factors related to image quality such as contrast ratio and viewing angle are directly related to safety for the driver. Thus, OLED is to be adopted more. Referring to the requirements of automotive OLED, he finally commented that improving reliability, such as lowering the luminance drop due to temperature changes and preventing damage to OLED due to high humidity, will be key to OLED for its entry into the automotive display market.

The automotive display is likely to lead the market for next-generation displays following mobile devices and TVs. Various OLED panel makers such as BOE and Visionox, as well as LG Display and Samsung Display, are showing automotive displays at domestic and international exhibitions. Denso also invested Japanese yen 30 billion in JOLED early 2018 to compete with Korean panel makers. Meanwhile, the market for OLED displays for automobiles led by Samsung Display and LG Display is expected to grow to US$ 540 million in 2023 according to UBI Research’s recently published “Automotive OLED Display Report”.

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.

According to the Nikkei newspaper, Japanese auto parts maker Denso is expected to invest 30 billion yen in JOLED to compete with Korean panel makers in the automotive display market.

Through this investment, Denso will have a 15% stake in JOLED and become one of the largest shareholders of the State-backed Innovation Network Corp. Japan Display also owns 15% of JOLED.

It is very important for a next-generation car to have a display system that allows the driver to easily receive information from various sensors and cameras. JOLED is known to actively enter the automotive display market by partnering with Denso, a company that is specialized in automotive electronics and control systems.

JOLED and Denso are planning to develop OLEDs for digital dashboards and mirror camera systems. OLEDs can be flexibly shaped compared to LCDs, allowing for better customization inside the vehicle.

Meanwhile, JOLED supplied 21.6 inch 4K OLED panels to Asus using inkjet technology in January 2018. JOLED plans to mass-produce inkjet-based OLEDs in 2019.

In addition, JOLED is under fund-raising 5 billion yen each from Panasonic, Sony, Sumitomo chemical, and Screen Holdings. The company plans to mass-produce OLED panels at its display plant in Ishikawa Prefecture.

Nikkei 신문에 따르면, 일본의 자동차 부품 제조사인 Denso가 JOLED에 300억엔을 투자하여 자동차 디스플레이 시장에서 한국 패널 업체들과 경쟁할 것으로 알려졌다.

Denso는 이번 투자를 통해 JOLED의 약 15%의 지분을 갖게 되며 State-backed Innovation Network Corp의 최대 주주 중 하나가 된다. Japan Display도 JOLED의 15%를 보유 중이다.

차세대 자동차에는 운전자가 여러 센서와 카메라에서 수집 된 정보를 쉽게 제공 받을 수 있는 디스플레이 시스템이 매우 중요하다. JOLED는 자동차용 전자 장치와 제어 시스템에 능통한 Denso와 파트너 관계를 구축함으로써 자동차 디스플레이 시장에 적극적으로 진출하려는 것으로 알려졌다.

JOLED와 Denso는 디지털 대시 보드와 미러 카메라 시스템용 OLED를 개발 할 계획으로 알려졌다. OLED는 LCD 대비 유연한 형태의 모양을 구현할 수 있기 때문에 자동차 내부에 더 잘 맞춤 설계 할 수 있다.

한편, JOLED는 2018년 1월 잉크젯 기술을 이용하여 21.6 inch 4K OLED 패널을 Asus에 공급한 바 있다. JOLED는 잉크젯 기반의 OLED를 2019년에 대량 생산을 한다는 계획이다.

또한, JOLED는 Panasonic과 Sony, Sumitomo chemical, Screen Holdings로부터 각각 50억엔을 모금하고 있다. 이시카와현의 디스플레이 공장에서 OLED 패널을 대량 생산 할 계획이다.
