HYBRID OLED HAVING IMPROVED EFFICIENCY

摘要

An organic light-emitting device (OLED) including an anode; a cathode; a blue light-emitting layer disposed between the anode and the cathode and includes at least one blue host and at least one fluorescent blue dopant; a first light-emitting layer disposed between the anode and the blue light-emitting layer, including a first phosphorescent dopant and a host; and a second light-emitting layer disposed between the blue light-emitting layer and the cathode, including a second phosphorescent dopant and a host.
