1. 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;
(e) a plurality of light sensitive elements located together with said rear electrode layer; and
(f) wherein each of said light sensitive elements include a transistor;
(g) wherein each of said light sensitive elements includes a first transistor that senses ambient light, and a second transistor that is inhibited from sensing ambient light with respect to said first transistor;
(h) wherein a terminal of said first transistor is connected to a terminal of said second transistor with a first conductor; and
(i) wherein said first conductor is capacitively coupled to a common line wherein said light sensitive elements determine a change in the light level to a level less than the ambient light level.
