Title:
MANUFACTURING METHOD FOR LENTICULAR GRATING
Document Type and Number:
WIPO Patent Application WO/2021/233096
Kind Code:
A1
Abstract:
A manufacturing method for a lenticular grating, comprising: providing a substrate (100), wherein the substrate (100) is provided with at least two lenses (101); and forming at least one light-shielding structure (102) on the substrate (100), so that the at least one light-shielding structure (102) corresponds to a junction area of the adjacent lenses (101) in the at least two lenses (101). According to the method, light irradiated onto the lenticular grating is shielded by means of the at least one light-shielding structure (102) formed on the substrate (100) of the lenticular grating, so that the problem in the lenticular grating of an incorrect light projection position of a sub-pixel caused by an irregular cross-section structure formed in the junction area between the adjacent lenses (101) is solved, and the crosstalk between left-view and right-view images can be reduced or eliminated.
