摘要：

Hybrid white organic light-emitting diodes (WOLEDs), created by combining fluorophors and phosphors, have the potential to provide high efficiency, long lifetime and good color-stability for display and lighting applications. The efficacy of hybrid WOLEDs broke 30 lm/W in 2006, however, progress toward developing high performance devices for lighting has been limited. There is plenty of room to improve the efficacy, scale and cost-effectiveness of hybrid WOLEDs for commercial applications in the future. In this review, the history and current status of hybrid WOLEDs are summarized, some successful strategies are highlighted, and our efforts on developing hybrid devices with different blue fluorophors are presented. Finally, a discussion is given to address some of the challenges for hybrid WOLED technology and prospects for its commercialization.
