For the first time, double blue emitting layers have been functioned as the main exciton generation zone to achieve high-performance three-color phosphorescent white organic light-emitting diodes (WOLEDs). The WOLED exhibits the maximum forward-viewing external quantum efficiency (EQE) and power eff...
