Adjustable liquid crystal slit grating, three-dimensional display device and adjusting method of device

Abstract

The invention provides a liquid crystal slit grating which comprises a first polarizing film, a first substrate, a drive electrode structure, a first alignment layer, a liquid crystal layer, a second alignment layer, a public electrode structure, a second substrate and a second polarizing film which are stacked in sequence, wherein the drive electrode structure comprises a drive electrode layer and a lead wire layer; the drive electrode layer comprises a plurality of parallel strip-shaped drive electrodes; the drive electrodes are divided into a plurality of drive electrode groups; each drive electrode group comprises the N drive electrodes; the lead wire layer comprises N lead wire electrodes; the N drive electrodes in the drive electrode group are electrically connected with the N lead wire electrodes in a one-to-one correspondence manner respectively. The invention further provides a three-dimensional display device adopting the liquid crystal slit grating and an adjusting method of the device. The liquid crystal slit grating and the three-dimensional display device have the advantages that the liquid crystal slit grating and the three-dimensional display device are automatically adjustable and the adjusting method is simple.

Description

technical field [0001] The invention relates to the field of stereoscopic display, in particular to an adjustable liquid crystal slit grating, a stereoscopic display device using the liquid crystal slit grating and an adjustment method thereof. Background technique [0002] There is a distance between the left eye and the right eye of a person, resulting in a slight difference in the viewing angle of the two eyes. Such a difference will cause a slight parallax in the scenes observed by the left eye and the right eye respectively, thus forming a stereoscopic image in the human brain. [0003] When viewing a general stereoscopic display device, it is necessary to wear stereoscopic glasses, so that a viewer who already wears glasses (such as myopia glasses, presbyopic glasses, etc.), in order to obtain a clear viewing effect, needs to overlap two pairs of glasses to make the stereoscopic display It is inconvenient to watch. In addition, since the width between the two temples ...

AI Technical Summary

Problems solved by technology

[0006] However, due to the complexity of the three-dimensional display, there needs to be precise cooperation between the liquid crystal slit grating and the display panel. Generally, the liquid crystal slit grating is attached to the display surface of the display panel. However, due to the limitation of the manufacturing process, Liquid crystal slit gratings often cannot be accurately attached to the display panel according to the design requirements, resulting in deviations in the separation of stereoscopic images, resulting in ghosting, unsatisfactory stereoscopic effects, and even the inability to produce stereoscopic images, which greatly limits the stereoscopic image. display applications that degrade the viewer's stereoscopic viewing experience
