Problems solved by technology

[0005] The disadvantage of the existing technology is that the selection of liquid crystals in the grating is limited, the refractive index distribution of the liquid crystals is limited by the deflection of the liquid crystals, resulting in a small viewing angle, and the cost of the liquid crystals is relatively high

Embodiment Construction

[0051]In order to improve the viewing angle of the grating and reduce the cost of the grating, the invention provides a grating, a display device and a manufacturing method of the grating. In this technical solution, since there are multiple options for polar liquids and non-polar liquids, the refractive index difference between the two liquids is relatively large, and the curved surface formed by the hydrophilic-hydrophobic conversion material layer has a large radian. Therefore, the range of refractive index distribution Larger for better viewing angles and lower cost for liquid compared to liquid crystal. In order to make the purpose, technical solution and advantages of the present invention clearer, the following specific examples are given to further describe the present invention in detail.

[0052] like figure 2 As shown, the structure diagram of the first embodiment of the grating of the present invention, the grating includes a first substrate 1 and a second substr...

Abstract

The invention relates to the technical field of display, and discloses an optical grating, a display device and a manufacturing method of the optical grating, partition walls arranged in such a manner of corresponding to every strip-like electrodes, respectively, and liquid layers arranged between every two adjacent partition walls, wherein the optical grating comprises a first substrate and a second substrate arranged in opposition to each other; a plane electrode is arranged on one side, facing the second substrate, of the first substate; a plurality of strip-like electrodes arranged at intervals are arranged on one side, facing the first substrate, of the second substrate; the partition walls are clamped between the first substrate and the second substrate; each partition wall comprises a conductive lug boss and a hydrophilic-hydrophobic switching material layer covering the conductive lug boss; the conductive lug boss is electrically connected with the corresponding strip-like electrode; each liquid layer comprises a polar liquid and a nonpolar liquid. Due to the adoption of the technical scheme, the visual angle of the optical grating can be increased and the cost can be reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a grating, a display device and a manufacturing method of the grating. Background technique [0002] With the continuous development of liquid crystal display technology, 3D (Three-Dimensional, three-dimensional) stereoscopic display technology has attracted much attention and has become an important frontier technology field in the display field. Raster 3D displays are precisely coupled gratings and 2D (two-dimensional) displays. According to the different gratings used, grating 3D displays are divided into two types: slit type grating 3D display and cylindrical lens type grating 3D display. Parallax images to synthesize stereoscopic images in the human brain. [0003] In 3D display technology, 3D display devices based on liquid crystal gratings have attracted much attention due to their simple structure, compatibility with liquid crystal technology, and good performance.
