VIBRATING GRATING-BASED NAKED EYE THREE-DIMENSIONAL DISPLAY METHOD AND APPARATUS

摘要

A vibrating grating-based naked eye three-dimensional display method and apparatus, relating to the technical field of naked eye three-dimensional display. To meet the double requirements for the limitation of a large three-dimensional viewing areas or non-three-dimensional viewing areas and for high-resolution display of three-dimensional images. The vibrating grating-based naked eye three-dimensional display method comprises the following steps: (1) creating a double-viewing-point three-dimensional synthetic image through a pixel unit-based three-dimensional image synthesis method; (2) manufacturing and then placing a grating in front of or behind a 2D display screen; (3) vibrating the grating structure obtained in the step (2) at a particular speed in horizontal, inclined and vertical directions, or vibrating the grating structure according to a specially-designed vibrating curve or with a sub-pixel, or a pixel, or a plurality of pixels, or a plurality of sub-pixels as base units; and (4) the double-viewing-point synthetic image varying as the vibrating grating structure, the direction of vibration and the rule of vibration change.
