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 3D display devices, the structure designed based on the principle of geometrical optics is not enough to meet the requirements for the control of light propagation in the display device, resulting in the presence of the display device and the immersion of the viewer. Poor, resulting in a poor viewing experience for the viewer

Abstract

The invention discloses a display device, relates to the field of display technology, and is used for improving viewing experience of viewers. The display device is used for virtual display, and the display device includes a display panel and a grating layer, along the center of the central area of ​​the left-eye field of view of the display device, pointing to the direction of the non-left-eye central area of ​​the field of view of the display device, and the left eye R The grating period of the grating area, the grating period of the left eye G grating area and the grating period of the left eye B grating area all gradually decrease, pointing to the center of the non-right eye field of view of the display device along the center of the right eye field of view center area of ​​the display device The grating period of the right-eye R grating area, the grating period of the right-eye G grating area and the grating period of the right-eye B grating area all gradually decrease in the direction of the area. The display device provided by the invention is used for 3D 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 3D display, the display device has a fixed center area of ​​the left eye ...
