Abstract

A light sensitive display.

Claims (16)

1 . A light sensitive display comprising:

(a) said display selectively causing pixels to provide light;

(b) a plurality of light sensitive elements located within said display, wherein said light sensitive elements are transistors; and

(c) a processor that determines at least one of said plurality of light sensitive elements that experiences a change in the light level to a level less than the ambient light level.

2 . The display of claim 1 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.

3 . A light sensitive display comprising:

(a) said display selectively causing pixels to provide light;

(b) a plurality of light sensitive elements located within said display suitable to sense ambient light;

(c) a processor that receives information from said light sensitive elements and determines regions of said display that experiences a change in the light level to a level less than the ambient light level and regions of said display where light in excess of said ambient light reaches said light sensitive elements.

4 . 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) a plurality of light sensitive elements located within said display wherein each of said light sensitive elements includes a first transistor that senses ambient light, a second transistor that is inhibited from sensing ambient light with respect to said first transistor; and

(e) a processor that determines at least one of said plurality of light sensitive elements that experiences a change in the light level to a level less than the ambient light level.

5 . The device of claim 4 wherein a terminal of said first transistor is connected to a terminal of said second transistor with a first conductor.
