Abstract

The invention provides a grating film and a three-dimensional display device. The grating film comprises a first substrate, a first microstructure, a second microstructure and a second substrate which are sequentially arranged, wherein the first microstructure is arranged on the surface of the first substrate; the second microstructure is arranged on the surface of the second substrate; the shape of the first microstructure is complementary to that of the second microstructure; the first microstructure is in anastomotic connection with the second microstructure. In the grating film, the first substrate and the second substrate are arranged on the outer sides of the first microstructure and the second microstructure respectively, so that the problems caused by surface dryness characteristics of the first microstructure and the second microstructure can be solved; the first substrate and the second substrate have different thicknesses, and the first substrate and the second substrate are arranged on one side near a 2D liquid crystal display module, so that the three-dimensional display device with different watching distances can be obtained; the three-dimensional display device further adopts a driving mode different from point reversal, so that positive and negative polarities of subpixels at positions corresponding to left and right eyes of a person are consistent at the same time point, and thus the screen flickering problem is solved and the display effect is improved.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to a grating film and a stereoscopic display device. Background technique [0002] Currently, a stereoscopic display device needs to take into account 2D (two-dimensional) display effects while realizing 3D (three-dimensional) functions, and the stereoscopic display device includes a grating film and a 2D liquid crystal display module. [0003] Wherein, the existing grating film includes a base material, a first microstructure formed by high refractive index optical glue and a second microstructure formed by low refractive index optical glue, the first microstructure is arranged on the surface of the substrate, and the second microstructure disposed on the surface of the first microstructure. Because the second microstructure of the existing grating film has surface-dry characteristics, that is, it is easy to scratch, the surface has adhesion, and is easy to absorb dus...
