Abstract

In this study, we report the thermally activated delayed fluorescence (TADF) organic light‐emitting diodes (OLEDs) having enhanced efficiency. We optimized TADF OLED by HTL, ETL materials and thickness. An enhanced power efficiency, current efficiency and external quantum efficiency were achieved in optimized TADF OLED.
