Three-dimensional display system

Abstract

The invention provides a three-dimensional display system. The display system comprises orientation backlight, multilayer liquid crystal sheets, a horizontal direction diffuser, a vertical direction diffuser and a raster. The orientation backlight is used for emitting light. A first layer of liquid crystal sheet, the horizontal direction diffuser, the other layers of liquid crystal sheets except for the first layer of liquid crystal sheet, the raster and the vertical direction diffuser are successively arranged along a light propagation direction. By using the three-dimensional display system,the light emitted by the orientation backlight generates an orientation light cluster through a combined effect of the liquid crystal sheets and the diffusers, and the light is ensured to fall on anassigned viewpoint so that double images and fuzzy images are not generated. The orientation light cluster can form a correct watch vision area, the vision area is not changed and parallax inversion is not generated. Each pixel can emit a plurality of different light to different directions, a display visual angle is enlarged and a display resolution is greatly increased.

Description

technical field [0001] The present invention relates to the field of three-dimensional display, and more particularly, relates to a three-dimensional display system. Background technique [0002] With the rapid development of science and technology and the improvement of the quality of life, people can no longer be satisfied with the perception and information provided by the two-dimensional flat display. In various fields such as related scientific research, military affairs and entertainment life, the necessity of collecting and reconstructing 3D information has become more and more prominent. At present, most of the three-dimensional display technologies utilize the binocular parallax principle of the human eye, that is, the human brain obtains three-dimensional vision by utilizing the difference in content entering the left and right eyes of the human being. Early access to 3D display information required wearing 3D glasses or helmets, which hindered natural visual expe...

Problems solved by technology

For the current three-dimensional display, since the lens intercept is less than or equal to twice the radius of curvature, the refractive index is generally 1.5. According to the above two formulas, the value range of θ is θ≤52°, that is, the stereoscopic viewing angle is small

[0014] In addition, in the current 3D stereoscopic display technology, the display resolution is inversely proportional to the number of viewpoints, that is, the more viewpoints, the more the resolution decreases.

It is difficult to achieve a resolution that guarantees the display effect in the case of dense viewpoints
