Abstract
A light sensitive display.
Claims45
A liquid crystal device comprising:
- (a) a front electrode layer;
- (b) a rear electrode layer;
- (c) a liquid crystal material located between said front electrode layer and said rear electrode layer;
- (d) changing an electrical potential between said rear electrode layer and said front electrode layer to selectively modify portions of said liquid crystal material to change the polarization of the light incident thereon;
- and
- (e) a plurality of light sensitive elements located together with said rear electrode layer.
