A naked-eye 3D display system suitable for laser projection

Abstract

The invention discloses a naked-eye 3D display system suitable for laser projection, According to directional light source projection display technology, by placing the light-emitting projection pathof the pointing projection combination in a vacuum-sealed enclosed space, so that the directional light source can project onto the projection screen completely and stably, thereby effectively improving the picture quality of the projection and the display effect of the naked eye 3D; and the directional light source has no air interference and is projected in a vacuum environment, thereby avoidingthe obstruction of the air flow and the sundries in the gas to the light; At that same time, the dust in the seal space can be effectively absorbed by the dust suction device, the preferred cryopumpand cooling fan can effectively control the temperature of the enclosed space, The spacing between the projection device and the projection screen can be adjusted conveniently by setting the gasket, and the shock absorbing mechanism can effectively avoid the influence of the external vibration on the display system. The display system has the characteristics of reasonable structure layout, stronganti-interference ability and good display effect.

Description

technical field [0001] The invention relates to the technical field of 3D display, in particular to a naked-eye 3D display system suitable for laser projection. 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. The invention patent w...

Problems solved by technology

[0004] However, although the projection-type naked-eye 3D display device of the above-mentioned technical solution has all the information of holographic display and has no distance limit, and realizes a large-format naked-eye 3D display, this solution does not systematically arrange the display device rationally. The projected image quality or resolution is limited, the display effect is unstable, and it is easily disturbed and affected by the real environment such as air, temperature, and vibration.
