Panasonic is working on OLED lighting panels, using printing methods. They prototypes a high efficiency panel at Printable Electronics 2009.
The OLED lighting panel features a luminance efficiency of 40lm/W and a CRI (color rendering index) value of 95. The external quantum efficiency is 36.1%, and the half-life of the luminance exceeds 20,000 hours when the initial luminance is 1,000cd/m2.
