Title:
LIGHT-EMITTING SUBSTRATE AND PREPARATION METHOD THEREFOR, AND LIGHT-EMITTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/039719
Kind Code:
A1
Abstract:
A light-emitting substrate, comprising: a base; and a plurality of light-emitting devices, which are disposed on the base, wherein the plurality of light-emitting devices comprise at least one first light-emitting device and at least one second light-emitting device. The at least one first light-emitting device comprises a first color light-emitting layer with a first thickness; the at least one second light-emitting device comprises a first color light-emitting layer with a second thickness, and a first material layer and a second color light-emitting layer, which are sequentially arranged, in a stacked manner and in a direction that is away from the base, on the first color light-emitting layer included in the second light-emitting device, wherein the second thickness is smaller than the first thickness; and the first material layer is configured to transport, to the second color light-emitting layer, holes transported from the first color light-emitting layer, and block electrons transported from the second color light-emitting layer, or the first material layer is configured to transport, to the second color light-emitting layer, electrons transported from the first color light-emitting layer, and block holes transported from the second color light-emitting layer.
