P‐197: Enhancing Top‐Emission OLED Performance Through the Introduction of Buffer Layers

This study introduces a novel method to enhance top‐emission OLED (TEOLED) performance using high‐surface‐energy metals, like aluminum, as buffer layers to control growth and achieve a smooth cathode surface. Optimization was further achieved by incorporating a bilayer electron injection layer with lithium fluoride (LiF), resulting in an 11.4% efficiency improvement and a 29% luminance increase.
