Title:
ORGANIC LIGHT-EMITTING DISPLAY AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/035900
Kind Code:
A1
Abstract:
An organic light-emitting display and a manufacturing method therefor. Each main pixel of a display area of the organic light-emitting display is defined with at least a first sub-pixel, a second sub-pixel and a third sub-pixel, wherein the first sub-pixel is a white light sub-pixel, the second sub-pixel includes a first light-emitting material, and the third sub-pixel includes a second light-emitting material; each main pixel further comprises a third light-emitting material, the material of the second sub-pixel comprises an intrinsic color region and a light-synthesis region, wherein the first light-emitting material of corresponding colours necessary for synthesizing white light in the light-synthesis region is stacked or mixed with a part of the third light-emitting material so as to form a synthesized white light sub-pixel; the other part of the third light-emitting material is stacked with the second light-emitting material, and the transmission distance of excitons generated by the second light-emitting material is less than the thickness of a functional layer where the second light-emitting material is located. The brightness and chromaticity of a picture can be improved, energy consumption can be effectively saved on, and the service life of the organic light-emitting display can be prolonged.
