Method, device, unit and system for backlight pointing naked-eye 3D display with uniform and no dark area

Abstract

The invention relates to an even and non-dark-space backlight pointing-type naked-eye 3D display method, device, unit and system. The method comprises the steps of projecting a corresponding image to a visual area unit through a light-emitting unit, wherein a viewpoint is located in the visual area unit; monitoring the moving direction of the viewpoint; changing the light-emitting state of the light-emitting unit corresponding to a visual area unit adjacent to the visual area unit where the viewpoint is located in the moving direction. According to the even and non-dark-space backlight pointing-type naked-eye 3D display method, device, unit and system, the state of the light-emitting unit is changed by monitoring the position and the moving direction of the viewpoint in real time, so that the viewpoint is always located in the visual area unit where the image is currently projected through the light-emitting unit in the moving process, and the naked-eye stereoscopic image visual experience of smooth transition in the visual area is kept.

Description

technical field [0001] The invention relates to the field of image display, in particular to a method, device, unit and system for a backlight pointing naked-eye 3D display with uniformity and no dark areas. Background technique [0002] 3D display is the most vital next-generation display technology, which mainly adopts the method of spatial multiplexing to provide different parallax images for both eyes. That is, the left eye is located in the left viewing area and can see the corresponding left-eye image, while the right eye is located in the right-eye viewing area and can see the corresponding right-eye image. The left-eye image and the right-eye image are a pair of stereoscopic images, so that the brain can fuse the two to form a 3D picture, and the viewer can feel the 3D stereoscopic picture. [0003] The current mainstream naked-eye 3D display technology is mainly based on the technology of cylindrical lens array, visual barrier grating and backlight pointing technol...

Problems solved by technology

These junctions appear as dark or gray areas between the binocular viewing areas at the best viewing distance. When viewing naked-eye 3D displays in these dark or dark areas, not only the crosstalk rate is high, but also the screen uniformity is poor.
