Abstract

The invention provides a lenticular raster. The lenticular raster comprises a first substrate and a second substrate, a first electrode layer located on the first substrate, a resin layer located on the first electrode layer, a second electrode layer located on the second substrate, a liquid crystal layer clamped between the resin layer and the second electrode layer. The first substrate and the second substrate are arranged oppositely. One side, facing the liquid crystal layer, of the resin layer is provided with multiple concave spherical surfaces. The lenticular raster has following beneficial effects: by taking the method that the multiple concave spherical surfaces are arranged close to the liquid crystal layer on the resin layer, the thickness of the liquid crystal layer on the concave spherical surfaces is in the state of gradual increase from the center to the periphery. The state of a large view angle can be achieved no matter where observers look from the top, the bottom, the left and the right or at an oblique angle. Therefore, a visible angle scope of 3D effect can be enlarged and the 3D three-dimensional display effect can be improved. The 3D display and the electronic device have larger visible angle ranges and better 3D three-dimensional display effect.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a lens grating, a 3D display and an electronic device. Background technique [0002] Glasses-free 3D display technology can realize the effect of 3D images when viewing text and pictures without using special glasses, making the technology closer to users' daily habits. Therefore, glasses-free 3D display technology has also become a future development trend. [0003] At present, for glasses-free 3D display devices, two-viewpoint areas are generally displayed, and the viewing angle range is narrow. The observer can only see 3D display images in these two areas. Can see 2D images or double images, or even not see the images. Therefore, there is an urgent need to provide a liquid crystal display device with a large viewing angle range. Contents of the invention [0004] The object of the present invention is to provide a lenticular grating, which can expand the vi...
