Problems solved by technology

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

Embodiment approach 1

[0056] Embodiment 1: The focal length of the scene in front is measured in partitions to obtain the depth of field information. Part: In order to realize the modulation of the light emitting angle of the light source, a modulation voltage signal needs to be applied U α Focus the lens (4) on the conductive liquid, and to obtain the modulated voltage signal, the focal length signal must be obtained, because the focal length signal A represents the distance between the diffuse reflection point of the real object and the camera, and the focal length signal can be converted into a modulated voltage Signal U α , it is unrealistic to measure the focal length of each real object diffuse reflection light point, so the method of partition measurement is used for measurement, and the part of obtaining the depth of field information includes:

[0057] - light-shielding wall (14) for blocking side light;

[0058] -Vertical light channel (15), used to filter the incoming light and obtain...

Embodiment approach 2

[0081] Embodiment 2: a naked-eye 3D local holographic display method, characterized in that it includes a part for obtaining depth of field information by partition measurement of the focal length of the front scene and a naked-eye 3D local holographic display including part;

[0082] Part of the divisional measurement of the focal length of the front scene to obtain the depth of field information: in order to realize the modulation of the light emitting angle of the light source, a modulation voltage signal needs to be applied U α Focus the lens (4) on the conductive liquid, and to obtain the modulated voltage signal, the focal length signal must be obtained, because the focal length signal A represents the distance between the diffuse reflection point of the real object and the camera, and the focal length signal can be converted into a modulated voltage Signal U α , it is unrealistic to measure the focal length of each real object diffuse reflection light spot, so the met...

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...
