Liquid crystal parallax barrier and stereo display device and correction method thereof

Abstract

The invention relates to the technical field of stereo display, and discloses a liquid crystal parallax barrier and a stereo display device and a correction method thereof. A first electrode structureis arranged on the side, opposite to a liquid crystal layer, of a first substrate of the liquid crystal parallax barrier, the first electrode structure comprises multiple driving electrode sets whichare arranged in a periodic mode, each driving electrode set comprises at least two driving electrode layers, each driving electrode layer comprises multiple driving electrodes which are arranged at intervals, a gap portion is arranged between each two adjacent driving electrodes, and the driving electrodes and the gap portions of each two adjacent driving electrode layers are oppositely arranged;the driving electrodes which apply the first preset driving voltage in each driving electrode set form a shading portion, the driving electrodes which apply the second preset driving voltage in eachdriving electrode set form a photic portion, and when the driving electrodes which apply the first preset driving voltage and the driving electrodes which apply the second preset driving voltage change, the positions of the shading portions and the photic portions change correspondingly, so that over dependency and excessive demands on the laminating accuracy can be effectively 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 stereoscopic (3D) display device superimposes a grating on a conventional display panel, and the grating can refract images in different directions, so that the visual images of the left eye and the right eye are separated, so that users can 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. 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 vertical electrode structure...

AI Technical Summary

Problems solved by technology

This has very strict requirements on the process conditions and process control of the bonding equipment, and the investment cost is huge

And once the lamination is out of position, the expected light splitting effect cannot be achieved, and a better 3D display effect cannot be achieved, so it cannot be put into use, resulting in a huge waste of cost and resources
