Problems solved by technology

At present, the main 3D technology is the stereoscopic 3D image display technology. By providing the two eyes of the observer with plane images with different perspectives, the 3D display effect is synthesized by the human brain. There is a problem that the focus distance and the convergence distance of the binocular views are inconsistent, which is easy Causes visual fatigue of the observer, and is limited by the number of parallax images that the display system can provide, the display viewing angle that the existing stereoscopic technology can achieve is often limited
Holographic display technology can reproduce phase and amplitude information at the same time. In theory, it is the most ideal three-dimensional display technology. less than practical application requirements of the technology

Embodiment 1

[0063] A three-dimensional image display system based on a single multi-directional view generation unit, the structure of the three-dimensional image display system using a single multi-directional view generation unit 20 is as follows figure 1 As shown: the narrow bandwidth spectrum array generating unit 10 is composed of a microdisplay chip array 11, a small lens array 12 and a filter aperture array 13 with the same surface lattice structure, wherein the resolution of the rectangular microdisplay chip is m×n, and the pixel pitch is δd, the focal length of the small lens is f", the diameter of the filter aperture is δΦ, the microdisplay chip array 11 and the filter aperture array 13 are respectively placed on the front and rear focal planes of the small lens, and the distance between the array nodes along the x and y directions is Δd; A narrow bandwidth spectrum array generating unit 10 and a projection lens 21 with a focal length of f are combined into a multi-directional vi...

Embodiment 2

[0073] In a 3D image display system based on a single compound multi-directional view generation unit, in a display system based on a single multi-directional view generation unit, when the pixel pitch δd of the micro-display chip selected by the system is relatively large, the size of the micro-display chip with the same resolution becomes smaller. In addition to the space occupied by the outer frame of the chip, the chip spacing Δd is also large when the chip is arranged in an array on a plane, and the angular resolution arcsin (Δd / f) is large, and the image displayed by the system will be obviously distorted, which will affect the display effect. . In order to obtain a three-dimensional display with a large viewing angle range, the ratio of the plane size distributed by the microdisplay chip array to the focal length f of the projection lens 21 is required to be as large as possible; when Δd increases, although it can be maintained by selecting a projection lens 21 with a lo...

Embodiment 3

[0076] The three-dimensional image display system based on multiple multi-directional view generation units, the three-dimensional image display system based on the composite multi-directional view generation unit 30 is used to solve the problem of excessive size of the micro-display chip, and multiple multi-directional view generation units 20 can also be used It is solved by combining the half-mirrors 40 into one. Taking three multi-directional view generation units 20, 20', 20'' as an example, the structure of the I-type control unit 110 is not shown as follows: Figure 10 . The projection lenses 21 of 20', 20'' are completely coincident with the mirror images of the synthetic half mirrors 40 and 40' and the projection lens 21 of 20, but the narrow bandwidth spectrum array units 10 of 20', 20'' are respectively relative to the synthetic half mirrors. The mirror images of the mirrors 40 and 40' and the narrow bandwidth spectrum array unit 10 of the mirror 20 are completely ...

Abstract

The invention relates to the technical field of three-dimensional image display, in particular to a three-dimensional image display system and a three-dimensional image display method based on a micro display chip array. The three-dimensional image display system based on the micro display chip array comprises a rotary platform, at least one narrow-band spectrum array generation unit, at least one multi-direction view generation unit, at least one compound multi-direction view generation unit, at least one rotary reflector, at least one diffraction membrane, at least one synthetic semi-reflection lens, at least one light path turning unit, at least one light path extension unit, a spatial mouse unit, a control unit and a field lens. Through a reasonable design for an image projection light path, spatial separation between the distribution space of a projection parallax image and a display area of a target image is performed, a spatial mouse capable of being used for indication and menu operations for three-dimensional image display is introduced into the display area of the target image, and the interactive three-dimensional image display is achieved.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional image display, and more particularly, to a three-dimensional image display system and method based on a microdisplay chip array. Background technique [0002] Because two-dimensional display is difficult to clearly and accurately express the depth information of the third dimension, people have been working on the research of display technology that can display three-dimensional scenes - three-dimensional image display technology. At present, the main 3D technology is the stereoscopic 3D image display technology. By providing the two eyes of the observer with plane images with different perspectives, the 3D display effect is synthesized by the human brain. There is a problem that the focus distance and the convergence distance of the binocular views are inconsistent, which is easy It causes visual fatigue of the observer, and is limited by the number of parallax images that the d...
