69‐3: Late‐News Paper: Enhanced Performance of Quantum Dot Light Emitting Diode via Optimizing PVK and Poly‐TPD Mixture Ratio for Hole Transport Layer

For high‐performance quantum‐dot light‐emitting‐diode (QD‐LED), it is imperative to resolve the charge imbalance. In this paper, the solution to resolve the charge imbalance is introduced to mix two polymer hole transport layer (HTL) materials.
