The invention relates to the technical field of three-dimensional
image display, in particular to a small-spacing visual region guiding type three-dimensional display
system and method. The small-spacing visual region guiding type three-dimensional display
system comprises a display screen, a light splitting device, a guiding device, a
control unit, a selectable switching device, a diaphragm array, a tracking feedback unit and an orthogonal gating control device, wherein the light splitting device is used for guiding emergent light of different groups of pixels on the display screen to be visible to different initial visual regions respectively; under the assistance of other
system components, the arranged guiding device deflects different pixel subsets of the pixel group corresponding to each initial visual region to emit light to each corresponding guiding visual region in the different guiding visual region set; and guide visual region sets are used for covering different eyes of an observer, and the distance between every two adjacent guide visual region sets is not larger than the
pupil diameter of the observer. According to the small-spacing visual region guiding type three-dimensional display system and the method, through
monocular multi-view presentation, focusing-convergence conflicts can be overcome, three-dimensional display capable of achieving natural focusing is achieved, and the three-dimensional visual comfort degree is improved.
