Title:
MULTI-VIEWPOINT 3D DISPLAY SCREEN AND MULTI-VIEWPOINT 3D DISPLAY TERMINAL
Document Type and Number:
WIPO Patent Application WO/2021/110041
Kind Code:
A1
Abstract:
The present application relates to the field of 3D images, and discloses a multi-viewpoint 3D display screen, comprising: a display panel, comprising a plurality of composite pixels, each composite pixel comprising a plurality of composite sub-pixels, and each composite sub-pixel comprising a plurality of sub-pixels corresponding to a plurality of viewpoints; and a plurality of gratings provided in parallel on the plurality of composite pixels, each of the gratings comprising a first oblique edge and a second oblique edge and obliquely covering the plurality of composite pixels, so that the first oblique edge and the second oblique edge intersect with the composite sub-pixels to define an inclination angle; in the composite sub-pixels, the sub-pixels, which intersect with or are adjacent to the first oblique edge, forming first terminal sub-pixels, and the sub-pixels, which intersect with or are adjacent to the second oblique edge, forming second terminal sub-pixels; and the inclination angle enabling that: in an extension direction of the first oblique edge, the colors of the first terminal pixels, in at least part of the adjacent composite pixels, having the largest overlapping area with the gratings are different. The present application can solve the problems of red vignetting or other colors in 3D display. The present application further discloses a multi-viewpoint 3D display terminal.
