Consumer display manufacturers are increasingly interested in white organic light emitting devices (WOLEDs), because these devices offer thinner display profiles, and in combination with color filters eliminate the need for high-resolution shadow masks. Additionally, WOLEDs are well suited for general-purpose illumination, since the power efficiencies of laboratory devices have surpassed that of today's commercial incandescent bulbs. In this paper, we report on an all phosphorescent 25 cm2 WOLED lighting system that achieves (31±3) lm/W at 850 cd/m2 with CIE coordinates (0.37, 0.36), and an external quantum efficiency of (29±3)%.
