Problems solved by technology

Existing technology already has the method that realizes basic left-right stereoscopic display type, left-right stereoscopic single-person tracking type and left-right stereoscopic high-definition display type on flat-panel TV, and realizes the method that plane is compatible with described stereoscopic display, but has not yet implemented on flat-panel display And on the rear projection display, realize the realization method of continuous-view stereotype, surround-view stereotype and tilt-down surround-view stereotype, and there is no method for free stereoscopic display based on flat panel and rear-projection display, which is compatible with multiple stereos

Embodiment Construction

[0133] Such as figure 1Shown is a schematic diagram of the existing basic left and right stereoscopic display terminal viewing area distribution. The black diamond-shaped area in the figure is the left and right viewing areas separated by space. When the two eyes are respectively located in the left and right viewing areas, stereoscopic images can be viewed. In the horizontal direction parallel to the display screen, there are a series of discrete left and right stereoscopic viewing areas, single viewing areas and left and right overlapping areas; in the direction perpendicular to the display screen, the viewer also has a A series of discrete left and right stereoscopic viewing areas, single viewing areas, and left and right overlapping areas; the total viewing area is too small, and the scope of the viewing area must be enlarged.

[0134] As shown in Figure 2A, it is a schematic diagram of the principle of virtual image formation before the front slit grating of the present i...

Abstract

The invention relates to a method for realizing free stereo video display terminals of a continuous stereo type, a sweeping stereo type and an upward/downward sweeping stereo type on a flat-panel display and a rear-projection display based on a parallax baffle. The method adopts a virtual image forming method, a control method of a slit grating and a slit optical screen and a time division display method to perform free stereo display of plane, continuous view, sweeping and upward/downward sweeping respectively, and can perform any two or three or total hybrid displays in the same display scene through pixel-level shielding control, achieve the high-definition stereo display of the continuous view and the high-definition stereo display of the sweeping by increasing divided time or reducing the number of view points, effectively eliminate double images existing in three free stereo displays through adjacent orthogonal orientation, and eliminate interference through the sectional synchronization of the slit grating and the slit optical screen.

Description

technical field [0001] The invention relates to a stereoscopic display technology, in particular to a flat stereo hybrid compatible flat panel and projection autostereoscopic video display based on a parallax barrier. Background technique [0002] Video display technology is developing rapidly. Flat panel displays (such as LCD liquid crystal display, PDP plasma display, FED field emission display, OLED organic electroluminescent display and CRT ultra-thin display, etc.) have large display area, good effect, light weight, and easy placement. It has become the mainstream technology in the field of display technology at present; projection stereoscopic display can display extremely large scenes, and is the main solution for large scene display; stereoscopic display can better virtual real space and create a virtual space, which can make People get a high sense of immersion when viewing. Autostereoscopic (without glasses) display is the basic requirement for stereoscopic display...
