Embodiment 1
[0019] The grating strip in this embodiment is a spiral surrounding structure with equal pitch; the pitch is 0.3~0.8mm, and the line width of the grating strip is 0.02~0.1mm, such as figure 2 shown.
Embodiment 2
[0021] The grating strips in this embodiment are circular structures arranged at equal intervals and concentrically. Each circular grating strip is evenly divided into four equal arcs, and the gap between adjacent circular arcs is 0.01 mm. The width of the gap between the adjacent annular grating strips on the ITO glass plate is 0.3~0.8mm, and the line width of the grating strips is 0.02~0.1mm, such as image 3 shown.
[0022] In this embodiment, the naked eye can see the consistent space division from all directions, the display is uniform and consistent, the response speed reaches 10 ms, and the 3D effect of the full viewing angle is achieved.

Abstract
The invention provides a full-perspective 3D grating structure used for a liquid crystal screen. The full-perspective 3D grating structure comprises an ITO glass plate and grating strips adhered on the ITO glass plate. The grating strips are annularly arranged on the ITO glass plate with equal intervals. With application of the full-perspective 3D grating structure used for the liquid crystal screen, fixed and consistent phase difference is presented to the naked eyes no matter which perspective direction so that inconsistent images are generated to the left eye and the right eye of people, uniform and consistent 3D images are generated via human brains and the full-perspective 3D effect is realized.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a grating structure for making a liquid crystal screen present a 3D display effect. Background technique [0002] 3D is three-dimensional graphics, which belongs to virtual three-dimensional technology. 3D technology is a technology that achieves three-dimensional effects in terms of vision and hearing by using computer operations. At present, there are many ways to realize 3D technology in the market, including timing method, space method and various 3D glasses technologies. Technology generally uses a space segmentation method to realize 3D technology, so that the left eye and right eye of a person will have a phase difference, see inconsistent images, and cause the brain to generate a 3D image. [0003] The traditional 3D grating structure is to arrange several parallel grating strips on the ITO glass plate, and the grating strips are pasted on the ITO glass pl...
