Title:
ORGANIC ELECTROLUMINESCENT DEVICE AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2021/035872
Kind Code:
A1
Abstract:
An organic electroluminescent device (10) and a display panel (60). The organic electroluminescent device (10) comprises a first organic electroluminescent unit (20), a second organic electroluminescent unit (30) and an insulating layer (40); the first organic electroluminescent unit (20) and the second organic electroluminescent unit (30) are provided in a stacked manner; the insulating layer (40) is provided between the first organic electroluminescent unit (20) and the second organic electroluminescent unit (30) and is made of a light-transmitting material; and the first organic electroluminescent unit (20) and the second organic electroluminescent unit (30) are configured to be connected to an alternating current power supply (V). The technical solution omits the process of conversion from alternating current to direct current, and reduces the electric energy loss.
