Another company is starting to work on OLED lighting : Doosan Corporation Electro-Materials. They have signed an agreement with the Korean Institute of Industrial Technology (KITECH) to co-develop the OLEDs. They plan to use white phosphorescent materials that feature high efficiency and long lifetimes.  Another company from the Doosan group ( Doosan DND ) has been working on OLED production systems since 2004 (although we haven’t heard any news from them in quite some time).
