Abstract
The invention features techniques for presenting more than one perspective views to each eye of the viewer, through generating viewing zones with an interval smaller than the diameter of the viewer's pupil by display panel/grating pair/pairs. In the first method, the arraying direction of the small-interval viewing zones is designed having an appropriate small inclination angle to the line connecting the viewer's two pupils, so as to cover each eye with more than one viewing zones which are different with each other. In the extreme case, 4 small-interval viewing zones can implement 3D display with two views for each eye. This is absolutely different with existing grating-based 3D display, which aligns viewing zones along the direction with a small angle (<π/4) to the line connecting the viewer's two pupils and thus a rather large number of small-interval viewing zone is needed for covering the viewer's two eyes.
