Naked-eye 3D display device and method for realizing naked-eye 3D display

Abstract

The invention discloses a naked-eye 3D display device and a method for realizing naked-eye 3D display. The naked-eye 3D display device comprises a light source arranged below a view window generation device and the view window generation device. The view window generation device comprises a phase information modulation device used for phase modulation, and a view angle image information modulation device used for amplitude modulation, wherein pixels of a view angle image generated by the view angle image information modulation device are matched and aligned with viewpoint pixels generated by the phase information modulation device. By the utilization of a holographic imaging and wavefront conversion principle, the phase information modulation device is ingeniously utilized for phase modulation, the view angle image information modulation device is simultaneously used for amplitude modulation, and the pixels of the view angle image generated by the view angle image information modulation device are matched and aligned with the viewpoint pixels generated by the phase information modulation device. Namely, the assembling with the phase modulation function is combined with the display technology with the amplitude modulation function, so that naked-eye 3D display is realized, and 3D image information is presented.

Description

technical field [0001] The invention belongs to the field of naked-eye 3D display of surrounding vision, and in particular relates to a pixelated pointing projection screen and a method for realizing naked-eye 3D display by a surrounding-viewing naked-eye 3D display device based on the screen.
