Abstract

The invention discloses a display device and a display method and belongs to the technical field of display. The display device comprises a display panel and a grating structure, wherein the display panel comprises a pixel layer; the pixel layer comprises alternately arranged first pixel groups and second pixel groups; the grating structure comprises alternately arranged open areas and shading areas, wherein orthographic projections of the orthographic projections of the open areas on the display panel are located in the first pixel groups; and the orthographic projections of the shading areason the display panels cover the second pixel groups. When the display device is in an anti-peep display mode, a plurality of first pixel groups display a target image and a plurality of second pixelgroups display an interference image different from the target image; and when the display device is in a shared display mode, the plurality of first pixel groups display the target image and the plurality of second pixel groups display a shared image same as the target image, thereby effectively enriching the display mode of the display device.

Description

technical field

[0001] The present invention relates to the field of display technology, in particular to a display device and a display method. Background technique

[0002] In order to prevent peeping of content displayed on display devices such as mobile phones or tablet computers, some display devices with anti-peeping functions appear on the market.

[0003] At present, a grating structure can be formed on the light-emitting side of the display device, and the viewing angle range of the display device can be reduced through the grating structure, so as to realize the anti-peeping function.

[0004] However, after the grating structure is formed on the light-emitting side of the display device, the display device is always in the anti-peeping display mode, so the display mode of the display device is relatively simple. Contents of the invention

[0005] Embodiments of the present invention provide a display device and a display method. It can solve the problem that t...
