A naked-eye 3D local holographic display method

Abstract

The technical problem to be solved by the present invention is to provide a naked-eye 3D local holographic display method, which belongs to the technical field of stereoscopic display. It includes the part of determining the focal length of the front scene to obtain the depth of field information and the naked-eye 3D local holographic display part. Naked-eye 3D local holographic display includes: primary focus, precise adjustment of luminous pixel luminous angle, 3D display drive circuit, pixel circuit drive, and voxel cone angle axis pointing; add tiny liquid to each pixel of the existing display The focusing lens changes the diffuse reflection of ordinary pixels to control the light angle of each pixel or a few pixel light sources, and realizes naked-eye 3D local holographic display. The principle of image display is the same as the projection effect of real scene images with naked eyes Consistently, brain imaging will not cause additional burden, and long-term use will not cause headaches or eye fatigue. This display has rigid market demand.

Description

technical field [0001] The invention relates to a naked-eye 3D local holographic display method, which belongs to the technical field of 3D display. Background technique [0002] At present, naked-eye 3D display has always been the technical bottleneck that flat-panel displays are trying to break through. The reasons why human naked eyes can see 3D images are as follows: [0003] 1. Binocular parallax is different from the distance between two human eyes (the average value is 6.5cm), so for the same scene, the relative positions of the left and right eyes are different, which results in binocular parallax, that is, what the left and right eyes see is different. difference image; [0004] 2. Motion parallax. Motion parallax is produced by the relative movement between the observer and the scene, which changes the size and position of the scene on the projection of the retina, resulting in a sense of depth; [0005] 3. The adjustment function of the eyes (adaptive adjustme...

[0004] 2. Motion Parallax

However, there is no mature technology to realize naked-eye 3D display, especially local holographic display.
