/in , , /by

At the Lighting Fair 2019 held in Tokyo Big Sight from March 5 to 8, 2019, Nippon Electric Glass (NEG) attracted the attention of the audience by exhibiting a large number of OLED lighting produced in collaboration with Kaneka, OLEDWorks and Lumlight. NEG, which produces ultra-thin glass for OLED lighting, introduced ‘Internal Extraction Layer (IEL)’ and ‘HX-1’, which improve external luminous efficiency, and high refractive index glass.

And NEG presented two OLED lighting panels were made in collaboration with Kaneka, a rechargeable OLED lighting ‘LUCE T1’, and a rotatable wall lighting ‘LUCE W1’. OLED lighting panels consist of square panels and rectangular panels with 3000K and 4000K color lighting, while square panels are in volume production, while rectangular panels are in progress.

In addition, NEG presented OLEDWorks ‘Brite 3’ series. ‘Brite 3’ has started mass production in the third quarter of 2018, efficiency is over 80 lm / W, color rendering is over 90, and color temperature is 3000K and 4000K.

Lastly, NEG exhibited the ‘OLED EYECARE LAMP’ stand by Lumlight. A represent said “OLED lighting would be a very useful lighting for infants and young people because it is less glare and feels very weak.

OLED display and lighting are expected to become increasingly applied to the interior and exterior of automobiles.

At CES 2018, Samsung Electronics introduced the OLED-applied dashboard. LG Electronics unveiled the center fascia with 14-inch OLED, and OLED set makers continue to exhibit their OLED applications for automobiles.

At the 10th CAR-ELE JAPAN held in TOKYO BIG SIGHT(Tokyo International Exhibition Center) on 17th, several companies including Tianma and Truly exhibited automotive OLED displays and lighting.

Tianma exhibited 4.2-inch, 5.46-inch and 5.99-inch OLED panels. The 5.99-inch OLED was a full-screen OLED, and the company official said “The full screen will be applied not only to mobile devices but also to automobiles such as CIDs and navigation systems due to the nature of automotive displays sensitive to visual impacts.” It is said they produced the OLED Panel with high luminance, including 5.46-inch and 4.2-inch OLED with luminance of 650 cd/m2, ensuring good high visibility under sunlight. In addition, they announced that they will manufacture unbreakable flexible type of OLED even though the exhibited OLEDs were all rigid type.

Truly exhibited 5.5-inch OLED panel. The company’s official mentioned that although they can not disclose detailed specifications, it should be further developed in terms of reliability for the application to the current automotive displays. In addition, they announced that automotive potentials such as autonomous vehicles are so huge that the importance of displays that can provide visual information will become even more important, and therefore they will invest in it.

Lastly, Nippon Electric Glass introduced OLED lighting which was created in collaboration with OLEDWorks. “This was created as interior lights and taillights for vehicles.” and “The OLED lighting substrate uses IEL(internal extraction layer) to improve more efficiency when applied to indoor lights, and better visibility when applied to taillights,” explained the company’s official.”

Meanwhile, in relation to OLED lighting, OLED light source companies such as LG Display and Osram supplied the OLED lights for tail lights to finished car makers such as Mercedes-Benz and BMW. In particular, it is expected to start the OLED lighting market in earnest, for example LG Display’s announcement of full-scale operation of the Gen5 OLED light source production line in December.

제 10회 CAR-ELE JAPAN에서 다수의 업체들이 자동차용 OLED 디스플레이와 조명을 전시

OLED 디스플레이와 조명은 자동차 실내외에 더욱 더 적용 될 것으로 예상된다.

지난 CES 2018에서 Samsung Electronics는 OLED가 적용 된 계기판을 선보였으며 LG Electronics는 14 inch대의 OLED가 적용 된 센터페시아를 공개하는 등, OLED 세트 업체들의 자동차용 OLED 어플리케이션 전시는 지속적으로 이루어 지고 있다.

17일 일본 도쿄 빅사이트에서 개최 된 제 10회 CAR-ELE JAPAN에서도 Tianma와 Truly등 다수의 업체들이 자동차용 OLED 디스플레이와 조명을 전시하였다.

Tianma는 4.2 inch와 5.46 inch, 5.99 inch OLED 패널을 전시하였다. 5.99 inch OLED는 full screen 형태의 OLED로써, 업체 관계자는 “시각적 영향을 많이 받는 자동차용 디스플레이 특성 상 full screen은 모바일 기기 뿐만 아니라 CID와 네비게이션 등 자동차 내부에도 적용 될 것”이라 밝혔다. 5.46 inch와 4.2 inch OLED 패널의 휘도는 650 cd/m2로, 햇빛 아래에서도 야외시인성이 좋아야 하기 때문에 높은 휘도의 OLED 패널을 제작하였다고 업체 관계자는 언급했다. 또한, 전시 된 OLED는 모두 rigid type 이지만 깨지지 않는 flexible type의 OLED도 제작 할 것임을 밝혔다.

Truly는 5.5 inch OLED 패널을 전시하였다. 업체 관계자는 자세한 사양을 공개할 수는 없지만 현재 자동차용 디스플레이에 적용 되기엔 신뢰성 측면에서 좀 더 발전되어야 함을 언급하였다. 이어서, 자율주행자동차 등 자동차가 발전 할 요소가 많은 만큼 시각적 정보를 제공할 수 있는 디스플레이의 중요성도 더욱 더 부각 될 것이기에 이를 위한 투자도 진행 될 것이라 밝혔다.

마지막으로 Nippon Electric Glass는 OLEDWorks와 협업하여 제작 된 OLED 조명을 선보였다. 업체관계자는 “자동차 실내 조명과 후미등용으로 제작 되었다”고 설명하며, “OLED 조명의 기판을 IEL(internal extraction layer)로 사용함으로써 실내 조명에 적용 시 더욱 더 효율이 향상되고 후미등에 적용 시 시인성이 향상되는 효과가 있다”라고 밝혔다.

한편, OLED 조명은 LG Display와 Osram 등 OLED 광원 업체들이 Mercedes-Benz와 BMW 등의 완성차 업체에 tail light용 OLED 조명을 납품한 바 있으며, 특히 LG Display는 지난 12월 Gen5 OLED 광원 양산라인의 본격 가동을 알리는 등 OLED 조명의 본격적인 시장 개화가 기대되고 있다.
