ABSTRACT:
An apparatus and method of controlling the light intensity in a light source of variable emission affected by a drive signal. Spatial optical integration based upon light summation is incorporated into the accompanying encasement device at a backlight source by means of a light source support structure that allows light not directed toward a viewed surface, such as an LCD, to serve as a control input to the light drive signal.
