Abstract

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 shadow masks. Additionally, WOLEDs are well suited for general-purpose illumination, and laboratory results show that their power efficiencies have surpassed that of incandescent bulbs. To replace current backlight technologies with WOLEDs, further increases must be made in the power efficiency of blue and red phosphorescent devices, and in the power density of OLEDs. In this paper, we report on a blue-red-green 6" square striped lighting panel emitting >100 lumens, and on a stacked OLED (SOLED) 6" square panel. The SOLED consists of a red and green OLED connected by a 70 nm- thick aluminum electrode that simultaneously serves as the cathode for the bottom green device and as the anode for the top red device.
