Abstract:White organic light‐emitting devices (WOLEDs) exhibit promising applications as white illumination and background light, but achieving high efficiencies, and high color quality for the WOLEDs still remains difficult. Herein, to enhance exciton utilization and improve the color quality of WOLEDs, a new sandwich configuration of an ultrathin orange phosphorescent layer located between two blue thermally activated delayed fluorescence (TADF) layers is proposed, and the working mechanism is investigated.
