Title:
DISPLAY SUBSTRATE, METHOD FOR MANUFACTURING SAME, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/233400
Kind Code:
A1
Abstract:
The present application relates to the technical field of display, and provides a display substrate, a method for manufacturing same, and a display device. Pixel areas of the display substrate are divided into multiple pixel groups; multiple flow guide strips are provided on the surface of a pixel defining layer between two at least partly adjacent pixel areas of each pixel group; a flow guide groove is formed between adjacent flow guide strips to distribute ink to allow the ink to be uniformly distributed in all pixel areas of the pixel group. By controlling the ink ejection amounts of all the pixel groups, the thickness uniformity of a common layer structure of the entire display substrate can be ensured, high-resolution inkjet printing is achieved, and the limitation of the size of a display product to high-resolution inkjet printing is overcome.
