Problems solved by technology

Therefore, the focus-convergence conflict caused by the lack of monocular physiological depth cues is contrary to the characteristics of the same binocular convergence distance and monocular focus distance in the natural state, resulting in physiological visual fatigue, which is not conducive to the realization of ideal 3D display technology

Embodiment 1

[0050] The structural diagram of a time-division multiplexing module that increases the number of viewpoint presentations in the present invention is as follows figure 1 As shown, it includes a clear aperture array 10 and a control unit 20; the clear aperture array 10 is composed of clear apertures arranged in a one-dimensional direction and can be gated in time sequence, and the control unit 20 and the clear aperture array 10 and the external display screen; the control unit 20 controls the timing gate of each clear aperture in the clear aperture array 10, and controls the external display screen to synchronously load corresponding display content.

[0051] When using the module, the module is combined with the eyepiece of the external stereoscopic glasses, or used as the eyepiece alone in the naked-eye three-dimensional display technology, and the timing gate of each clear aperture and the synchronous refresh of the external display screen are controlled by the control unit 2...

Embodiment 2

[0073] The second time-division multiplexing method of the present invention increases the number of viewpoint presentations. In this method, the time-division multiplexing module described in Embodiment 1 is used in a three-dimensional display system based on stereoscopic glasses. The structural diagram of the eyepiece corresponding to the right eye is as follows figure 1 shown. Through the eyepieces of the external stereo glasses, different parts of the content displayed on the display surface are respectively guided to the eyes of the observer. The difference between this method and the time-division multiplexing method based on stereo glasses in Implementation 1 is that the method for determining the effective viewpoint area is different, and specifically includes the following implementation steps:

[0074] SSS1. The clear aperture array 10 consisting of K clear apertures is attached to the eyepiece of the external stereoscopic glasses and placed;

[0075] SSS2. divide t...

Abstract

The invention relates to the technical field of three-dimensional image display, in particular to a time division multiplexing module and method for increasing the viewpoint presentation number.The module comprises a clear aperture array and a control unit.The clear aperture array is composed of clear apertures which are arranged in the one-dimensional direction and can achieve time-sequence gating.The control unit is electrically connected with the clear aperture array and an external display screen.The control unit controls time-sequence gating of the clear apertures in the clear aperture array, and controls the external display screen to synchronously load the corresponding display content.The clear aperture array is attached to an eye lens of three-dimensional display glasses or independently adopted as the eye lens under the naked eye three-dimensional display technology, the single-eye receiving light number is increased on the basis of vision persistence by controlling the time-sequence gating of the clear apertures and synchronous refreshing of the external display screen through the control unit, light spots capable of being naturally focused can be formed in space by combining two or more light beams, focusing-convergence conflicts are inhibited or eliminated, and the three-dimensional vision comfort is improved.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional image display, and more specifically, to a time-division multiplexing module and method for increasing the number of viewpoint presentations. Background technique [0002] Traditional 3D display technologies are mostly based on stereoscopic technology. The observer receives a corresponding view with both eyes, and uses binocular convergence to form a 3D depth perception by the brain, but loses the monocular physiological depth clues. Therefore, the focus-convergence conflict caused by the lack of monocular physiological depth cues is contrary to the characteristics of the same binocular convergence distance and monocular focus distance in the natural state, resulting in physiological visual fatigue, which is not conducive to the realization of ideal 3D display technology . Therefore, the overcoming of convergence-focus conflict is an urgent scientific problem to be solved at pre...
