We report a 0.39-in. quantum dot light-emitting diode (QLED) microdisplay with full high-definition (FHD, 1920 × 1080) resolution by integrating a red top-emitting QLED on a complementary metal–oxide–semiconductor (CMOS) backplane. By optimizing the microcavity structure and constructing a suitable energy-level structure for the QLED devices, the performance of the large-area (4.9 × 8.7 mm) top-emitting device with normal structure reached 13,936 cd/m of brightness at 5-V bias with 13.3% external quantum efficiency (EQE). Notably, the optimal device showed a low turn-on voltage of 1.7 V, which matched well the voltage output of the CMOS backplane. Our work demonstrates the great promise of QLED microdisplays for applications in head-mounted augmented reality/virtual reality (AR/VR).
