ABSTRACT:
A light sensitive display that includes a front electrode layer, a rear electrode layer, a liquid crystal material. The display includes a light sensitive element with at least two terminals and a transistor with at least three terminals. A readout system determining when light sensed by the light sensitive element is less than the ambient light and determining the region of the display that the light is less than the ambient light.
