ABSTRACT:
A rear projection television receiver incorporates 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 individual facets of a given prism lens element form different angles with respect to a vertical plane. 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, thereby giving a great deal of control over the shape of the envelope.
