A video display for two or three dimensions has a flat liquid-crystal screen which ejects light from the plane at a selectable line. One or, in the case of a 3-D display, several video projectors project a linear image into the plane from an edge. A complete image is written on the screen by addressing the line with appropriate images as it is scanned down the screen. To screen a three-dimensional image, the video projectors, each projecting an image as seen at a slightly different angle, combine to constitute a three-dimensional display which produces a three-dimensional image that is one line high. |
