Liquid crystal slit grating, and stereo display device and calibration method thereof

Abstract

The invention relates to the technical field of stereo display, and discloses a liquid crystal slit grating, and a stereo display device and a calibration method thereof. The liquid crystal slit grating includes a first substrate and a second substrate which are oppositely arranged, and a liquid crystal layer arranged between the first substrate and the second substrate; a first electrode structure is arranged on one side facing, the liquid crystal layer, of the first substrate; a second electrode structure is arranged on one side, facing the liquid crystal layer, of the second substrate; the first electrode structure includes a plurality of drive electrode groups which are arranged periodically, and each drive electrode group includes a plurality of drive electrodes which are arranged at intervals; in each drive electrode group, the drive electrodes having the first preset drive voltage corresponding form a shading portion, and the drive electrodes having the second preset drive voltage correspondingly form a light transmitting portion; when the drive electrodes having the first preset drive voltage and the drive electrodes having the second preset drive voltage, positions of the shading portion and the light transmitting portion change correspondingly, and the independence and demand of the laminating precision can be avoided.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to a liquid crystal slit grating, a stereoscopic display device and a correction method thereof. Background technique [0002] The mainstream glasses-free 3D (stereoscopic) display device superimposes a grating on a conventional display panel. The grating can refract images in different directions, separate the visual images of the left eye and the right eye, and allow users to see 3D images. In order to obtain a better 3D display effect, when performing naked-eye stereoscopic display, there needs to be precise cooperation between the grating and the display panel. [0003] Currently, liquid crystal slit gratings are widely used in naked-eye 3D display devices. On existing naked-eye 3D display devices, in order to effectively avoid aliasing, small color lines, and compression of the viewing area, and improve resolution, liquid crystal slit gratings generally adopt a ve...

AI Technical Summary

Problems solved by technology

[0004] In order to ensure the bonding accuracy of the liquid crystal slit grating and the display panel, the process conditions and process control of the bonding equipment have very strict requirements, and the investment cost is huge. Moreover, once the bonding occurs, the expected light-splitting effect cannot be achieved. Glasses-free 3D display devices cannot achieve better 3D display effects, resulting in a huge waste of cost and resources
