P‐144: Ultra‐High Brightness Quantum‐Dot Light‐Emitting Diodes with ZnO Nanoparticles Charge‐Control Layer

This study explores the performance enhancement of QLEDs by incorporating ZnO nanoparticles (ZnO NPs) as a charge control layer (CCL) between two quantum dot emitting layers. The utilization of the CCL significantly improves the device's luminance performance, achieving a maximum luminance (Lmax) of 102,029 cd/m 2 for blue, 2,191,507 cd/m 2 for green, and 870,199 cd/m 2 for red. This demonstration creates a new route to design impact QLED architecture for next generation displays and lighting.
