69‐1: Invited Paper: Improving Efficiency and Brightness in Colloidal Quantum Dot Light‐Emitting Diodes

In this paper, we introduce multilateral strategies to improve the efficiency and brightness of quantum dot light‐emitting diodes. First, electrically and thermally endurable device architecture is adopted for highly bright light‐emission. Second, an exciton harvesting layer consisting of blue‐emitting thermally‐activated delayed fluorescent materials is introduced to improve device efficiency. Our approaches realize remarkable improvements in the device performance.
