ABSTRACT:
A screen for a rear projection television receiver comprises a circular Fresnel lens element and a lenticular lens array. In order to adjust the location of the vertical audience envelope to optimize screen brightness for different viewing positions, the center of the Fresnel lens is displaced with respect to the center of the viewing screen. The principal light rays passing through the Fresnel lens are bent with respect to the lenticular array, thereby angling the vertical audience envelope with respect to the screen.
