Abstract
The present disclosure relates to an OLED display panel. With the OLED display panel, a higher luminous efficiency is achieved by selecting a thermally activated delayed fluorescent material for doping into an organic light emitting layer and applying a compound having a specific energy level to match, thereby the luminous efficiency of an organic photo electronic device is improved.
