Abstract
To achieve wide‐gamut and high‐efficiency tandem white OLED (WOLED) microdisplays, we propose a new structure leveraging from the high‐order antinodes and patterned microcavities. The color gamut coverages of 95% Rec. 2020 and 92% Rec. 2020 can be achieved in B/G/R WOLED with a moderate microcavity and B/YG WOLED with a strong microcavity, respectively. We have also boosted the optical efficiency by 62% by optimizing the B/YG WOLED structure. Such a WOLED microdisplay helps to reduce the power consumption of virtual reality (VR) and mixed reality (MR) displays while keeping a wide color gamut.
