Description
Technical Field
The invention relates to the technical field of naked eye 3D, in particular to a naked eye 3D display device suitable for an LED screen.
Background
3d is an abbreviation for three-dimensional, i.e., three-dimensional graphic. 3d graphics are displayed in a computer, that is, three-dimensional graphics are displayed in a plane. Unlike the real world, a real three-dimensional space has a real distance space. The computer only looks like the real world, so that the 3d graphics displayed on the computer are seen as if the human eyes are real. Human eyes have the characteristic that the human eyes are big at near and small at far, and can form stereoscopic impression. The naked-eye 3D technology can be broadly classified into three technologies, namely, light barrier type, lenticular lens type, and directional backlight 3D technology. In the optical barrier type 3D display technology, a polarizing film and a polymer layer are additionally arranged between a liquid crystal display panel and an internal light emitting device, and when an image is displayed in front of a viewer through the liquid crystal display panel, the polarizing film can distinguish the images received by the left and right eyes, so that a 3D image is formed in the brain of the viewer. The directional light source 3D technology requires two background light sources when rendering a 3D picture. When the left eye and the right eye of a viewer receive pictures at the same time, the light sources in different directions are sequentially and alternately lightened, and the left eye and the right eye pictures are alternately displayed in front of the viewer through the 3M reflecting film. However, the current 3D technology of the directional light source is not mature enough to meet the requirement of definition. The principle of the cylindrical lens light 3D technology is that a layer of cylindrical lens is added in front of a display screen, and the cylindrical lens light 3D technology has the advantages of good 3D display effect and no influence on brightness. Naked eye 3D display device on the market at present adopts the cylindrical lens light 3D technique to make more, but its single structure of these naked eye 3D display devices does not support to go up and down, and it is difficult to remove simultaneously, and functional poor, decorative effect is poor simultaneously, and in addition, some users use the in-process of naked eye 3D for a long time, lead to eye fatigue easily, and simultaneously, some users also have 3D vertigo, can't watch naked eye 3D for a long time.
