High-efficiency white phosphorescent OLEDs for lighting

Organic light emitting devices (OLEDs) are viewed as a potential next generation lighting source. Phosphorescent OLED (PHOLED) technology, with its inherently high efficiencies, represents the best opportunity to meet the challenging requirements of lighting. We discuss the requirements of OLEDs for lighting applications and present the state-of-the-art of white PHOLEDs, which have demonstrated the luminous efficiencies exceeding 30 cd/A at CIE coordinates of (0.35, 0.33).
