Abstract

The invention discloses a grating rear-mounted naked-eye 3D display system based on a directional light source. According to the directional light source projection display technology, the light projection path of the directional projection combination is placed in a vacuum-sealed airtight space, so that the light emitted by the directional light source The projection has no air interference and is projected in a vacuum environment, avoiding the influence of air flow and impurities in the gas on the light, and effectively realizing that the directional light source can be completely and stably projected on the projection screen, thereby effectively improving the quality of the projection image Naked-eye 3D display effect; at the same time, the vacuum state of the confined space can be guaranteed in real time through the pump component, the optimal cryopump and cooling fan can effectively control the temperature of the confined space, and the installation of gaskets can facilitate the adjustment of the projection device and the projection screen during installation. The distance between them can effectively prevent the display system from being affected by external vibrations by setting a shock absorbing mechanism. It has the characteristics of reasonable structural layout, strong anti-interference ability and good display effect.

Description

technical field

[0001] The invention relates to the technical field of 3D display, in particular to a grating rear-mounted naked-eye 3D display system based on a pointing light source. Background technique

[0002] Looking back at the development history of the display industry, from the original black and white TV to color TV, to the current high-definition TV, and high-tech products such as VR and AR, people's visual needs are constantly improving, so naked-eye 3D display technology came into being. In recent years, naked-eye 3D display technology has developed rapidly, among which 3D technology of slit grating, 3D technology of lenticular lens and 3D technology of pointing light source have become the mainstream technology in the large-screen advertising market.

[0003] In terms of optical principles, due to the diffusion of light sources, images at different angles in space are not unique. Therefore, when human eyes observe 3D images, it is easy to cause visual fatigue....

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application shall have the usual meanings understood by those skilled in the art to which the present invention belongs.

[0027] Such as figure 1 , figure 2 As shown, a grating rear-mounted naked-eye 3D display system based on a directional light source includes a directional light source 1, a projection device 2, and a projection screen 3. The directional light source and the projection device form a directional projection combination. Specifically, the projection screen is located at Pointing to the light output end of the projection combination, the light emitted by the pointing projection combination is projected onto the projection screen, that ...
