Title:
ORGANIC LIGHT-EMITTING DISPLAY SUBSTRATE, MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/168999
Kind Code:
A1
Abstract:
An organic light-emitting display substrate, a manufacturing method therefor, and a display device. The method for manufacturing the organic light-emitting display substrate comprises: providing a substrate (100); forming a pixel defining layer (200) on the substrate (100), where the pixel defining layer (200) defines multiple subpixel areas (300A, 300B, and 300C); printing an ink containing a material of a first sublayer of a first electrode in the multiple pixel areas (300A, 300B, and 300C); and drying the printed ink to form the first sublayer (410) of the first electrode. The method forms the first sublayer (410) of the first electrode simply by means of inkjet printing and increases the display quality and use performance of the organic light-emitting display substrate manufactured.
