Showa Denko (SDK) is a chemical producer established in 1908 in Japan, with a wide range of products and target markets.
SDK develops OLED lighting technologies, with aims to produce 80lm/W 40,000 hours white OLEDs - although it's not clear if this plan is still on track. SDK is using UDC's PHOLED materials.
Sumitomo Chemical has been established in 1913, and since then has been researching and producing industrial chemicals and materials. Sumitomo has been working with CDT on PLED materials, and has acquired the company in July 2007.
Sumitomo was engaged in soluble OLED material design for both OLED lighting and OLED displays. The company's materials were used by JOLED in its printed monitors, and in 2018 Sumitomo invested in JOLED (which is no longer in business).
Toshiba Corporation, based in Japan, is a multinational engineering and electronics corporation. Toshiba develops a wide range of products and services such as information technology equipment, components and materials, power stations, lighting, consumer electronics, household appliances and more.
Toshiba used to develop OLED lighting panels, with plans to enter the market in 2015 - which never materialized. Toshiba, together with Sony and Hitachi, formed Japan Display in 2011. The company used to develop flexible OLED panels, but that seems to have been abandoned as well.
Today the company is producing OLED TVs (using WOLED panels produced by LGD).
Ultimate Image Corporation (UMAGE) was established in 2011 in Taiwan, with an aim to become an OLED lighting developer. UMAGE designs and develops OLED lighting technologies and systems as a fabless company.
UMAGE currently deploys a tiled colorful interactive OLED lighting module based solution (C-OLED20).
WAC Lighting is a global innovative lighting designer and manufacturer for Luxury Residential, Commercial, Hospitality, Institutional, Retail and Architectural applications.
WAC Lighting developed several OLED luminaires using panels from LG Chem, OSRAM Orbeos OLED panels and Verbatim's Velve panels.
Yeolight Technology was spun-off Visionox in May 2015 to act as an independent company focusing on OLED lighting. The company produces and supplies OLED lighting panels.
In 2016 Yeolight introduced its first OLED lamp, using panels acquired from LG Display, but since then it started producing its own lighting panels, at a small-scale production line. Since 2017 Yeolight mainly targets the automotive market. In 2020 the company announced that the Hongqi H9 Sedan, which launched in China, uses the company's OLED taillights. Yeolight develops flexible OLED lighting panels, and is also developing PMOLED display modules produced on its line.
