59.2: High Performance Top Emitting OLED Devices

High performance top-emitting full color organic light-emitting diode (OLED) micro-displays were developed using a highly reflective anode patterned over active matrix single crystal silicon. Dual emission layer white OLED devices were fabricated using high Tg materials with typical efficiencies ∼ 10 cd/A and CIE x and y coordinates of 0.32 and 0.34 respectively. Stable color coordinates over a wide range of video grey levels were obtained from white using color filters. Room temperature operating luminance half-life at 20 mA/cm2 exceeds 6,000 hrs (>25,000 hrs in video mode). The optical characteristics of the devices were simulated using a full vector field calculation.
