Rohm developed a new (2nd-generation) OLED lighting panel that uses a red phosphorescent material. The new material results in a more efficient device - about 25-30lm/W, up from about 11lm/W in their first-generation all-fluorescent device.
Lumiotec (which is partly owned by Rohm) will start producing these new panels in "volume" within a few days (Lumiotec reported earlier that it will make around 60,000 panels a year). The new panel's size is 145x145mm (the same size of Lumiotec's older panels) and will cost ¥30,000 (about $365) - which is cheaper than Lumiotec's first-gen panels (the whole development kit used to cost The kit costs ¥84,000 - about $930). Lumiotec will also introduce other shapes and sizes. Here's our review of Lumiotec's older OLED Lighting panels.
