Document Type and Number:
WIPO Patent Application WO/2022/062227
Kind Code:
A1
Abstract:
A glass cover plate (51) of a display screen (50), and a preparation method therefor. An antiglare layer (511) is generated on a glass substrate by performing frosting processing on the glass substrate, so as to prepare an antiglare glass cover plate (51). During the frosting processing, frosting powder can be evenly sprayed on the glass substrate by a spray device, and then acid liquor is sprayed by the spray device onto the glass substrate covered with the evenly distributed frosting powder, so that evenly distributed particles (5111) are formed on the glass substrate, and the antiglare layer (511) is obtained, wherein the pore diameter of a spray nozzle of the spray device can be determined according to the size of subpixels of a pixel unit of the display screen (50), so as to control the size of the particles (5111) formed in the antiglare layer (511) to be less than or equal to half the size of the subpixels of the pixel unit of the display screen (50), so that the prepared glass cover plate (51) can realize an antiglare function and can also avoid a flickering phenomenon.
