Abstract
A video display for displaying a large image to an observer, comprising a screen for displaying patterns, the screen being formed of a plurality of separate areas each capable of receiving a segment of a pattern the segments collectively forming a complete frame of a pattern; projection means for projecting a segment of a pattern to each separate area of the screen in sequence; means for receiving each segment of a pattern and forming a complete frame; and means for illuminating the screen with collimated light to display a large area display.
Claims11
A three dimensional video display including:
- a screen (4) on which successive frames of patterns can be displayed and means (6) for projecting an array of collimated light beams which can illuminate the whole screen (4) through a series of discrete directions in synchronism with the display of successive frames;
- wherein said screen (4) includes a layer of liquid crystal material (13) located between a front plate (8) and a rear plate (9);
- a layer of light sensitive material (15), operable to change the voltage on the adjacent layer (13) of liquid crystal material;
- a reflective layer (14) between the liquid crystal material (13) and the light sensitive material and electrode structures (10, 11) on the inner faces of plates (8, 9) for applying a voltage across the liquid material (13), the electrodes (10, 11) forming collectively an array of separately addressable segments in the liquid crystal layer (13) and each collimated light beam 6 is arranged to illuminate the whole of front plate 8.
