Three-dimensional display device and system

Abstract

The invention provides a three-dimensional display device and a system, and relates to the technical field of three-dimensional display. The three-dimensional display device comprises a cylindrical grating film, a first glass gasket, an upper glass substrate, a lower glass substrate, a second glass gasket and a backlight unit, wherein the above parts are sequentially arranged from top to bottom. One ends of the cylindrical grating film, the first glass gasket, the upper glass substrate, the lower glass substrate, the second glass gasket and the backlight unit are flush with one another. The length and the width of the first glass gasket are respectively smaller than or equal to the length and the width of the upper glass substrate. The length and the width of the second glass gasket are respectively larger than or equal to the length and the width of the lower glass substrate. In this way, when a COF or a COG is damaged and needs to be repaired, the glass gaskets are not required to be removed from the surface of an upper polaroid. Therefore, the breakage of upper and lower glass substrates is reduced, and the maintenance becomes easier in operation.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to a stereoscopic display device and system. Background technique [0002] With the development of 3D technology, stereoscopic display devices are more and more widely used. Most of the existing stereoscopic display devices use columnar grating film technology. In order to ensure a larger viewing distance during use, a certain distance is set between the columnar grating film and the 2D liquid crystal display panel to provide a larger focal length. Usually, there are two ways to attach the columnar grating film to the 2D liquid crystal display panel: one is to attach the columnar grating film to the surface of the thinner glass side of the 2D liquid crystal display panel, and the other side of the glass or the grating film The distance between one side and the liquid crystal display panel is replaced by an air layer, which is usually called frame paste; the other is to...

AI Technical Summary

Problems solved by technology

In this way, when the COF or COG is damaged and needs to be repaired, the spacer glass must be disassembled from the surface of the upper polarizer. During the disassembly process, the upper and lower glass substrates are easily damaged, thus making maintenance very difficult.

[0004] In summary, there is currently no effective solution to the problem of difficult maintenance of display devices
