  • Patent number: 4636035
    Abstract: A rear projection screen consists of a Fresnel lens and a picture-forming screen placed in front of it. The picture-forming screen has vertical backward convex lenses on its back and vertical masking strips on its front and strip-shaped sections situated between the masking strips and opposite the backward convex lenses. Each of these is designed to refract light rays coming from behind so that they are directed towards the strip-shaped sections. In order to increase the picture resolution or definition capability of the screen and to avoid notch sensitivity between the backward convex lenses an intermediate lens is provided between every two of the backward convex lenses.
