Tandem white organic light-emitting diodes (WOLEDs) are promising for the lighting and displays field since their current efficiency, external quantum efficiency and lifetime can be strikingly enhanced compared with single-unit devices.In this invited review, we have firstly described fundamental concepts of tandem device architectures and Sleeping Mask their use in WOLEDs.Then, we have summarized the state-of-the-art strategies to achieve high-performance tandem WOLEDs in recent SPDIF Adapter years.Specifically, we have highlighted the developments in the four types of tandem WOLEDs (i.e.

, tandem fluorescent WOLEDs, tandem phosphorescent WOLEDs, tandem thermally activated delayed fluorescent WOLEDs, and tandem hybrid WOLEDs).Furthermore, we have introduced doping-free tandem WOLEDs.In the end, we have given an outlook for the future development of tandem WOLEDs.
