Problems solved by technology

[0004] At present, microprisms or microlenses are usually installed in the display device to control the transmission of light in the display device, that is, the existing display device usually adopts a structure designed based on the principle of geometric optics to realize the transmission of light in the display device. However, with the development of virtual display devices, the structure designed based on the geometrical optics principle is not enough to meet the requirements for controlling the propagation of light in the display device, resulting in the presence of the display device and the viewer's immersion. Poor, resulting in a poor viewing experience for the viewer

Abstract

The invention discloses a display device, relates to the technical field of display and aims to improve the viewing experience of viewers. The display device comprises a display panel and a grating layer arranged at the interior or exterior of the display panel, wherein the display panel comprises a plurality of R pixels, a plurality of G pixels and a plurality of B pixels; the grating layer comprises an R grating area corresponding to the R pixels, a G grating area corresponding to the G pixels and a B grating area corresponding to the B pixels; a center of a viewing field center area along with the display device is directed to a direction of a non-viewing field center of the display device; the grating periods of the B grating area, the G grating area and the B grating area are gradually shortened; the light emitted by positions corresponding to the R pixels of the display device, the light emitted by positions corresponding to the G pixels of the display device and the light emitted by positions corresponding to the B pixels of the display device are directly irradiated to eyes of the viewers. The display device provided by the invention is applied to virtual display.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] A display device is a device used to display text, numbers, symbols, pictures, or images formed by a combination of at least two of the text, numbers, symbols, and pictures. The display device may be a flat display device, a curved display device, a 3D display device, a near-eye display device, an AR / VR display device, and the like. [0003] With the development of display devices, people have put forward higher and higher requirements for the presence of the display and the immersion of the viewer. In order to improve the presence of the display and the immersion of the viewer, one of the key technologies is the need for the display The propagation of light in the device is effectively controlled. For example, for one of the display devices used for virtual display, the display device has a fixed central area of ​​the fie...
