Title:
ORGANIC LIGHT-EMITTING DIODE STRUCTURE AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/213601
Kind Code:
A1
Abstract:
An organic light-emitting diode structure and a display apparatus are provided. A light-emitting layer, a hole blocking layer and an electron blocking layer in the organic light-emitting diode structure meet the following conditions: T1(HBL)>T1(Host); T1(EBL)>T1(Host); T1(Dopant)>T1(Host); S1(Host)>S1(Dopant); T1(HBL) is the lowest triplet energy of a hole blocking layer material, T1(Host) is the lowest triplet energy of a host material, T1(EBL) is the lowest triplet energy of an electron blocking layer material, T1(Dopant) is the lowest triplet energy of a guest material, S1(Host) is the lowest singlet energy of the host material, and S1 (Dopant) is the lowest singlet energy of the guest material. The technical solution of the embodiment can help to increase the light-emitting efficiency and lifespan of a display device.
