ABSTRACT:
A reflective mirror screen for reflecting light projected from a CRT through a convex lens or from other projectors to only a specific observing area comprising a plurality of strips with parabolic surface or paraboloids. The principal axis of each parabolic surface or paraboloic is directed to the specific area located frontward of the reflective mirror screen so as to reflect the light projected thereon to the predetermined observing area. Any light projecting on the oriented-reflection reflective mirror screen will not be reflected to the specific observing area if the light does not come from the visual images projector or its adjacent area. Then, the people in the observing area will feel brighter image and relative little light interference than from conventional screens.
