Abstract
A light sensitive display.
Claims
exact text as granted — not AI-modified1 . A light sensitive display comprising:
(a) a light valve including a front polarizing element, a rear polarizing element, and light rotating material located between said first polarizing element and said rear polarizing element; and (b) a plurality of light sensitive elements located between said front polarizing element and said light rotating material; 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 . The display of claim 1 further comprising a processor that receives information from said light sensitive elements and determines at least one of regions of said display where ambient light is inhibited from reaching said light sensitive elements and regions of said display where light in excess of said ambient light reaches said light sensitive elements.Join the waitlist — get patent alerts
