Title:
ORGANIC LIGHT EMITTING DIODE DISPLAY SUBSTRATE, ORGANIC LIGHT EMITTING DIODE DISPLAY APPARATUS, AND METHOD OF FABRICATING ORGANIC LIGHT EMITTING DIODE DISPLAY SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2018/107722
Kind Code:
A1
Abstract:
A method of fabricating an organic light emitting diode display substrate having a subpixel region(201) and an inter-subpixel region(202) is provided. The method includes forming a pixel definition layer(20) on the base substrate(10), the pixel definition layer(20) being formed in the inter-subpixel region(202) and defining the subpixel region(201) of the organic light emitting diode display substrate; forming an insulating dielectric layer(50) on a side of the pixel definition layer(20) distal to the base substrate(10), the insulating dielectric layer(50) being formed to define a first aperture region(501) greater than the subpixel region(201); and, subsequent to forming the insulating dielectric layer(50), forming an organic light emitting layer(102) in each subpixel region(201) using a mask plate(30) placed on the insulating dielectric layer(50).
