Problems solved by technology

The viewing angle α of the 3D display device provided by the prior art is usually about 90°, and the viewing angle is relatively small.
[0007] In addition, the grating 02 must be processed on a transparent substrate 01 with a high refractive index. Usually, the transparent substrate 01 is made of glass material, which limits the selection of processing technology and materials.

Abstract

The invention discloses a display device, and belongs to the technical field of display. The display device comprises a display panel and a light modulation substrate which are arranged opposite to each other; the light modulation substrate comprises a substrate layer and a transparent dielectric layer, and the transparent dielectric layer is arranged on the side, close to the display panel, of the substrate layer; the substrate layer comprises a plurality of reflective grating structures and is covered with the transparent dielectric layer, and the surface of the side, away from the substratelayer, of the transparent dielectric layer is a transparent dielectric layer surface; the refractive index of the transparent dielectric layer is n, and n is greater than 1; light emitted from the display device converges into a plurality of luminous points at the exterior of the display device. Compared with the prior art, the visual angle of the display device is enlarged, and the processing difficulty is reduced.

Description

Technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display device. Background technique [0002] With the development of display technology, 3D (Three-Dimensional) display technology has become one of the research and development directions of display technology. In a 3D display device, precise control of the propagation direction of light is required. [0003] In a 3D display device provided in the prior art, a transmissive grating is used to modulate the direction of light. By adjusting the period of the grating, the wavelength of the coherent light source, the incident direction of the coherent light source and other parameters, the direction of the emitted light can be modulated. [0004] Please refer to figure 1 , figure 1 It is a schematic diagram of a grating structure in a 3D display device provided in the prior art. Wherein, a plurality of transmissive gratings 02 are provided on the transparent substrate 0...
