Problems solved by technology

This technology needs to assist human eye tracking. At the same time, in order to obtain a good three-dimensional effect, the size of the light source needs to be strictly controlled, so the brightness of the display is generally not high.

Abstract

A multidimensional free stereoscopic display device comprises a display device, a multidimensional position detection module, a pupil follow-up adjusting module and an intelligent optical module. The pupil follow-up adjusting module comprises a planar adjusting mechanism and a light modulator; a plane of the display device serves as a spatially 3D coordinate reference, the multidimensional position detection module is arranged to obtain a spatially 3D position of a viewer, a central processing module controls the pupil follow-up adjusting module in real time according to the spatially 3D position of the viewer, light emitted by the intelligent optical module passes the light modulator and is gathered into left and right viewing windows, the planar adjusting mechanism is positioned between the intelligent optical module and the light modulator to adjust the distance between the light modulator and the intelligent optical module, and left and right viewing windows are formed in different distances, namely, the left and right viewing windows are gathered in specific distance, and follow left and right pupils of the viewer in real time.

Description

[0001] 1. Technical field [0002] The invention relates to the technical field of information display, and is a multi-dimensional autostereoscopic display device. [0003] 2. Background technology [0004] When viewing objects with binoculars, it can subjectively produce sensations such as the thickness of the object being viewed and the depth or distance of space, which is called stereopsis. The images of the same viewed object on the retinas of both eyes are not exactly the same. The left eye sees more of the left side of the object from the left, while the right eye sees more of the right side of the object from the right. After the image information is processed by the high-level visual center, a three-dimensional object image is generated. However, when viewing objects with one eye, sometimes a certain degree of stereoscopic sensation can also be produced, which is mainly obtained through adjustment and monocular movement, and the generation of this stereoscopic sensatio...
