Display device

Abstract

The invention discloses a display device, relates to the technical field of display, and aims to improve the watching experience of watchers. The display device comprises a first display panel and a first optical grating layer, wherein the first display panel comprises a left display area and a right display area; the optical grating period of a left eye R optical grating area, the optical grating period of a left eye G optical grating area and the optical grating period of a left eye B optical grating area are gradually reduced from the center of a left eye view field central area of the left display area to the central area of a non-left eye view field of the left display area; the optical grating period of a right eye R optical grating area, the optical grating period of a right eye G optical grating area and the optical grating period of a right eye B optical grating area are gradually reduced from the center of a right eye view field central area of the right display area to the central area of a non-right eye view field of the right display area. The display device disclosed by the invention is applied to near-to-eye display equipment.

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 transmission of light in the device is effectively controlled. For example, for a display device for near-eye display, the display device includes a display panel including a left display ...

AI Technical Summary

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 near-eye 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 a less realistic effect displayed by the display device and less immersion for the viewer. Poor, resulting in a poor viewing experience for the viewer
