Reverse-view-free multi-view-point naked eye stereo display system and control method thereof

Abstract

The invention relates to the technical field of stereo display, in particular to a reverse-view-free multi-view-point naked eye stereo display system and a control method thereof. The reverse-view-free multi-view-point naked eye stereo display system comprises a specially-arranged backlight sources, a display screen and an optical film layer and further comprises a camera and a comprehensive processor, wherein the specially-arranged backlight sources, the display screen and the optical film layer are sequentially connected with a housing, and the camera, the comprehensive processor and the specially-arranged backlight sources are sequentially and electrically connected. The specially-arranged backlight sources comprise stereo light-emitting unit pair modules and compensation light source modules, wherein light emitted by the stereo light-emitting unit pair modules form a plurality of binocular view areas, dark areas and reverse-view areas through the display screen and the optical film layer, the comprehensive processor controls the stereo light-emitting unit pair modules and the compensation light source modules to adjust a light-emitting state and compensate the dark areas or the reverse-view areas according to face-eye positions detected by the camera. The reverse-view-free multi-view-point naked eye stereo display system and the control method can achieve that multiple audiences can view naked eye stereo images at appropriate positions and can view correct stereo images or planer images in original reverse-view areas and accordingly achieves reverse-view-free naked eye stereo display.

Description

technical field [0001] The present invention relates to the technical field of stereoscopic display, and more particularly, to a multi-viewpoint naked-eye stereoscopic display system without reverse vision and a control method thereof. Background technique [0002] Stereoscopic display technology has become an important part of the display industry. The display industry unanimously recognizes that the future stereoscopic display technology will inevitably develop in the direction of naked-eye stereoscopic display. [0003] The naked-eye stereoscopic display technology overcomes the dependence on auxiliary devices, allowing viewers to watch stereoscopic images with naked eyes without wearing any auxiliary devices. [0004] Multi-viewpoint naked-eye stereoscopic display is an important technology for popularizing naked-eye stereoscopic display. In order to achieve multi-viewpoint naked-eye stereoscopic display, various companies and research institutes have proposed their ow...

AI Technical Summary

Problems solved by technology

The resolution of naked-eye stereoscopic display achieved by these technologies will not decrease, but the refresh rate of LCD screens that can be used for stereoscopic display is generally between 120Hz and 240Hz. It is quite difficult to manufacture a screen with a higher refresh rate, and it is difficult to achieve real multi-person viewing; Moreover, the reverse viewing problem in the head and tail viewing areas still cannot be solved
