Abstract

The invention relates to a three-dimensional display method and system with high information flux and low crosstalk. A timing directional illumination module outputs illumination light of different directions according to a certain time series. The illumination light illuminates a light field display system formed by a display and a lens array from different angles. The light field display systemdisplays light field information of three-dimensional images of specified viewing angle ranges under illumination light of specified directions. The illumination light directions of the specified directions correspond to the specified viewing angle ranges one to one. The refresh timing sequence of the images displayed on the display of the light field display system are synchronously matched withthe illumination timing sequence of the timing directional illumination module, and three-dimensional image information in the same viewing angle range is superimposed and synthesized into a high-spatial-resolution three-dimensional image by time division multiplexing. According to the three-dimensional display system and method provided by the present invention, the three-dimensional image with ahigh resolution, a large viewing range and a large depth of field is provided, crosstalk noise does not exist, the image contrast is high, and the structure of the three-dimensional display system issimple.

technical field [0001] The invention relates to the field of three-dimensional display, in particular to a three-dimensional display method and system with high information throughput and low crosstalk. Background technique [0002] High-quality natural 3D display is one of the ultimate goals pursued by display technology. The current three-dimensional display technology can not meet people's demand for high-quality three-dimensional image information. Integrated imaging technology is 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 technology has greatly improved the display effect and performance, the resolution, depth of field, and viewing angle of the output 3D image are still limited by the system information flux and information crosstalk. Contents of the invention [0003] In view of this, the object of the present invention is to overcome the dis...
