Liquid-crystal slit grating, stereoscopic display device and calibration method of stereoscopic display device

Abstract

The invention provides a liquid-crystal slit grating which comprises a first polaroid, a first substrate, a drive electrode structure, a first direction distribution layer, a liquid crystal layer, a second direction distribution layer, a public electrode structure, a second substrate and a second polaroid in sequential stacked arrangement. The drive electrode structure comprises a drive electrode layer and a lead layer, the drive electrode layer comprises multiple bar-shaped drive electrodes which are arranged in parallel. The multiple bar-shaped drive electrodes are grouped into a plurality of drive electrode groups. Each drive electrode group includes N drive electrodes. The lead layer comprises N lead electrodes. The N drive electrodes in each drive electrode group are electrically connected with the N lead electrodes in one to one correspondence. The invention further provides a stereoscopic display device with the liquid-crystal slit grating and a calibration method of the stereoscopic display device. The liquid-crystal slit grating and the stereoscopic display device have the advantages of automatic adjustment and simplicity in the calibration method.

Description

technical field [0001] The invention relates to the field of stereoscopic display, in particular to a liquid crystal slit grating, a stereoscopic display device using the liquid crystal slit grating and a correction 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 the viewer who already wears glasses (such as myopia glasses, presbyopic glasses, etc.), needs to overlap two pairs of glasses in order to obtain a clear viewing effect, so that the stereoscopic display It is inconvenient to watch. In addition, since the width between the two temples of the 3D g...

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
