ABSTRACT:
A display device for detecting light includes a display surface, at least one light sensitive element arranged behind the display surface, and a liquid crystal element arranged between the display surface and the at least one light sensitive element. The liquid crystal element is operative to polarization shift light incident on the at least one light sensitive element based on an orientation of the plurality of molecules. The display device further includes at least one electrode operative to change an orientation of the plurality of molecules. The at least one electrode is patterned to define a geometry of at least one field of view of the at least one light sensitive element. A controller is electrically coupled to the at least one electrode, wherein the controller is configured to apply a voltage to the at least one electrode to effect selection of the at least one field of view.
