Claim:
1. Glasses-less 3D display method comprises the following steps (1) making a lighting screen for displaying the colors and brightness of display pixels; (2) making at least one shutter screen at front of said lighting screen with specified separation; (3) determining the positions and sizes of shutter pupils on said shutter screens and locations of lighting pixels on said lighting screen based on eye space concept including eye zone locations and eye zone sizes; wherein, in dynamic pinhole shutter method, positions and sizes of shutter pupils for a given display pixel on said lighting screen are determined by locations of corresponding eye zones and said display pixel; wherein, in mimic scene method, concept of the scene depth profile in picture space is used to determine corresponding shining point on said depth profile which virtually diverges rays for an selected image pixel in picture space, and the positions and sizes of shutter pupils on an inner shutter screen and an outer shutter screen and locations of lighting pixels on said lighting screen for a given image pixel in picture space are coordinately determined by locations of corresponding eye zones and said scene depth; (4) making address drivers with corresponding operation procedures to control all said screens dynamically; wherein, in dynamic pinhole shutter method, address drivers of shutter screen are used to form shutter pupils dynamically, associated with use of operation procedures of dynamic pinhole shutter method for scanning pixels on said lighting screen and for controlling the switching of shutter pupils on said shutter screen; wherein, in mimic scene method, address drivers of shutter screens and address drivers of lighting screen are used to coordinately form shutter pupils and lighting strips dynamically, associated with use of operation procedures of mimic scene method for lighting and scanning pixels on said lighting screen and for controlling shutter pupils on said shutter screens; wherein, said address drivers are specifically pre-built-in matrixes of address driving circuits; and (5) assembling said address drivers with said shutter screens at front of said lighting screen;
