Highly Efficient White OLED

摘要

Thereby providing an organic light emitting diode. The organic light emitting diode includes an anode and a cathode. Emitting layer having a first sub-emission layer and a second sub-emission layer is disposed between the anode and the cathode. The first sub-emission layer has a first host and a first dopant, and the second sub-emission layer has a second host and a second dopant. The first dopant and the second host are the same material.
