Substrate, optical grating, display panel and display device

Abstract

The invention provides a substrate, an optical grating, a display panel and a display device. The substrate, the optical grating, the display panel and the display device are used to raise a viewing angle of watching each viewpoint image according to an arrangement mode of sub pixels on the substrate, and due to the fact that a person only can watch a viewpoint image corresponding to each viewing angle from each watching viewing angle, the person can not be influenced by viewpoint images displayed at other watching viewing angles. The substrate comprises a plurality of sub pixel groups arranged in periodicity, wherein each sub pixel group comprises a first sub pixel unit used to display a first viewpoint image, a second sub pixel unit used to display a second viewpoint image and a third sub pixel unit used to display a third viewpoint image, the first sub pixel units are located in a first sub pixel column, the second sub pixel units and the third sub pixel units are located in a second sub pixel column, each second sub pixel unit is adjacent to each first sub pixel unit, and staggered with each first sub pixel unit at a preset distance in the vertical direction, and the preset distance is less than the width of each sub pixel unit.

Description

technical field [0001] The invention relates to the field of image display, in particular to a substrate, a grating, a display panel and a display device. Background technique [0002] With the popularity of touch tablet computers and the continuous increase of functions of tablet computers, users have higher and higher requirements for displays, especially in the field of games. Since some existing tablet computers can realize naked-eye stereoscopic display, that is, each sub-pixel row 101 displays the viewpoint image displayed by the sub-pixel row 101 through the grating 102, but as figure 1 As shown in , the first viewpoint image displayed by the first sub-pixel row is located in the first viewing angle area, that is, the vertical line display area, and the second viewpoint image displayed by the second sub-pixel row is located in the second viewing angle area, that is, the dot display area. And the third viewpoint image displayed by the third sub-pixel column is located...

Since some existing tablet computers can realize naked-eye stereoscopic display, that is, each sub-pixel row 101 displays the viewpoint image displayed by the sub-pixel row 101 through the grating 102, but as figure 1 As shown in , the first viewpoint image displayed by the first sub-pixel row is located in the first viewing angle area, that is, the vertical line display area, and the second viewpoint image displayed by the second sub-pixel row is located in the second viewing angle area, that is, the dot display area. And the third viewpoint image displayed by the third sub-pixel column is located in the third viewing angle area, that is, the gray shaded display area, wherein 1 is the first sub-pixel unit, 2 is the second sub-pixel unit, and 3 is the third sub-pixel unit. However, due to The viewing angles of the first viewing angle area, the second viewing angle area, and the third viewing angle area are very close, and are limited to within 180 degrees. You can only use multiple tablets to play chess and card games when you see the images of other players, and it is impossible for multiple people to use one tablet to play games

[0003] To sum up, the existing technology cannot realize that multiple people can watch different images on the same display device at the same time, and watching each image does not affect
