Abstract
A rear projection television receiver incorporates red, green and blue-image producing kinescopes and a screen which includes a prism lens arrangement. The prism lens comprises a number of prism lens elements made up of a plurality of lens surfaces or facets. The prism lens forms the vertical audience envelope of the screen, which results from a combination of the vertical audience envelope contributed by the differently angled facets. Planes normal to the horizontal centerline of the faceplates of the red and blue image-producing kinescopes are displaced with respect to a plane normal to the horizontal centerline of the faceplate of the green image-producing kinescope in order to correct vertical color shift.
