1. A light sensitive display comprising:
- (a) said display selectively causing pixels to provide light;
(b) at least one light sensitive element located within said display;
(d) modifying the intensity of a portable external light source directed at said display based upon said at least one light sensitive element;
(e) a readout system determining when the position of at least one of said plurality of light sensitive elements that has been inhibited from sensing ambient light, whereby said readout system distinguishes between ambient surroundings and said at least one of said plurality of light sensitive elements said inhibited from sensing said ambient light.

22. A liquid crystal device comprising:
-
(a) a front electrode layer;
(b) a rear electrode layer comprising a plurality of pixel electrodes;
(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 light guide together with an associated light source located in front of said front electrode layer to provide light thereto;
(f) a plurality of light sensitive elements located within said display;
(g) wherein the total internal reflections of said light guide is disrupted by contacting said display with a pointing device, where the pointing device has an index of refraction within 0.5 of the index of refraction of said light guide. - View Dependent Claims (23, 24, 25, 26)
