47.5L: Late-News Paper: Highly Efficient White OLEDs Using RGB Fluorescent Materials

A three-component white OLED device using fluorescent materials was developed for full-color displays. Very high power-efficiency of 17 lm/W@10mA/cm2 and long lifetime over 30,000hr@1,000cd/m2 were achieved by using new carrier transport materials with high mobility. Power consumption and half lifetime of a 2.2″ QVGA full-color display were estimated by simulation to be about 200mW(200cd/m2,100%ON) by combining the device with top-emission structure. This value is comparable to the state of the art of LCDs.
