Three-dimensional display apparatus with a wide viewing angle and increased resolution |
摘要 |
A three-dimensional display apparatus includes a liquid crystal panel 1 for displaying a discrete Fourier transformed image and a slit panel 2 having a convex lens function in a horizontal direction and a plurality of slits 3 arranged in a zig-zag manner, which is disposed in front of the liquid crystal panel 1. Since a spatial image is generated by such a configuration, a wide viewing region can be obtained. Since the number of slits positioned in the horizontal direction is increased as that of a slit pattern of a conventional slit array, the deterioration of resolution in the horizontal direction is reduced. Furthermore, since the slits are arranged in a zig-zag manner, the area of each light-shielding portion between sampling positions is reduced, thereby preventing an optical means from obstructing the observation of images.
