Abstract
A liquid crystal device comprises a front electrode layer, a rear electrode layer, and a liquid crystal material located between the front electrode layer and the rear electrode layer. The electrical potential is changed between the rear electrode layer and the front electrode layer to selectively modify portions of the liquid crystal material to change the polarization of the light incident thereon. A plurality of light sensitive elements located together with the rear electrode layer and a processor that determines at least one of the plurality of light sensitive elements that has been inhibited from sensing ambient light.
