Abstract

The invention relates to a three-dimensional display method and system with high information throughput and low crosstalk. The sequential directional lighting module outputs lighting light in different directions according to a certain time sequence; the lighting light illuminates the display and lens array from different angles. Light field display system; the light field display system displays the light field information of the three-dimensional image of the specified viewing angle range under the illumination light in the specified direction; the illumination light direction in the specified direction corresponds to the specified viewing angle range; the light field display system The refresh timing of the image displayed on the display is synchronously matched with the lighting timing of the timing directional lighting module, and through time-division multiplexing, the three-dimensional image information within the same viewing angle is superimposed to synthesize a three-dimensional image with high spatial resolution. The three-dimensional display system and method of the present invention provide a three-dimensional image with high resolution, large observation range, and large depth of field, without crosstalk noise, high image contrast, and a simple structure of the three-dimensional display system.

Description

Technical field [0001] The present invention relates to the field of three-dimensional display, and more particularly to a three-dimensional display method and system for high information flux low crosstalk. Background technique [0002] High quality natural three-dimensional display is one of the ultimate goals of technology pursuit. The current three-dimensional display technology does not meet the needs of high quality three-dimensional image information. Integrated imaging techniques are considered to be a natural three-dimensional display technology that is most likely to achieve large-scale applications in the near future. Although integrated imaging techniques have greatly improved in display effects and display performance, the resolution of the three-dimensional image thereof, the depth of view, and the viewing angle are limited by the system information flux and information crosstalk. Inventive content [0003] In view of this, the object of the present invention is to...
