Three-dimensional display method and device therefor
First Claim
1. A three-dimensional display method comprising the steps of:
- two-dimensionally arranging a plurality of image-generating sources in horizontal and vertical directions so as to differentiate between horizontal display directions;
generating a vertical display angular range common to entire images by expanding the display angular ranges only in the vertical direction with a vertical-direction diffusion plate so as to cancel differences in the vertical display directions and to enable a number of images different in horizontal display directions to be displayed; and
generating a display angular range overlap between adjacent images so as to enable the images to be smoothly switched.

Abstract
A three-dimensional display method and a device therefor are provided in which a number of images can be displayed in the horizontal directions while image skips can be eliminated by providing overlaps of display angular ranges between adjacent images having horizontal display directions.
A number of images are displayed in horizontal and vertical directions so that the display directions do not agree with each other, and by expanding vertical display angular ranges of entire images with a vertical-direction diffusion plate (17), a vertical display angular range common to the entire images is generated. In this common vertical display angular range, the entire images have different horizontal display directions. Thereby, a number of images can be displayed because image generating sources can be arranged also in the vertical direction in addition to the horizontal directions.
