Abstract

The invention relates to the technical field of display, and discloses a lens grating manufacturing method. The method comprises the steps that a substrate is provided, and the substrate is provided with at least one shading structure; and at least two lenses are formed on the substrate so that a junction area of adjacent lenses in the at least two lenses corresponds to the at least one shading structure. According to the method, at least one shading structure formed on a substrate of the lens grating shields light rays emitted to the lens grating so that the problem that the light ray projection positions of sub-pixels are wrong due to an irregular section structure formed in a junction area between adjacent lenses of the lens grating is solved; and left and right eye image crosstalk can be reduced or eliminated.

Description

technical field [0001] The present application relates to the field of display technology, for example, to a manufacturing method of a lens grating. Background technique [0002] At present, lenticular gratings are widely used in 3D displays. The 3D display based on lenticular gratings allows users to directly obtain 3D viewing effects through left and right eyes without using 3D glasses. [0003] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art: During the manufacturing process of the lens grating, due to the limitation of the precision of the manufacturing process, irregular The cross-sectional structure is very easy to form a distorted area. When the sub-pixel light passes through the distorted area, it is easy to project to the wrong position, causing crosstalk between the left and right eye images. Contents of the invention [0004] In order to provide a basic unde...
