Abstract

The invention discloses a display device and a display method, which belong to the field of display technology. The display device includes: a display panel and a grating structure. The display panel includes: a pixel layer including alternately arranged first pixel groups and second pixel groups; the grating structure includes: alternately arranged opening regions and light-shielding regions. Wherein, the orthographic projection of the opening area on the display panel is located in the first pixel group, and the orthographic projection of the light-shielding area on the display panel covers the second pixel group. When the display device is in the anti-peeping display mode, a plurality of first pixel groups display a target image, and a plurality of second pixel groups display an interference image different from the target image; when the display device is in a shared display mode, a plurality of first pixel groups display The target image is displayed, and the plurality of second pixel groups display the same shared image as the target image. The display mode of the display device is effectively enriched.

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...
