ABSTRACT:
This application embodies a dual purpose projection screen comprising a layer of milky white, translucent, flexible plastic film, coated on one side with a layer of reflecting metal, and a layer of flexible, white opaque material covering the metal reflecting layer. This screen serves as a high gain reflection screen for rays projected against the exposed side of the translucent film, with such rays passing through said translucent film and being reflected back by the metal layer, and as a standard reflecting screen for rays projected against the exposed side of the opaque layer, with said exposed side acting as the reflecting surface for such rays. Said opaque layer also acts as a backing or strengthening layer for the screen to enhance the strength, handling and mounting of the screen on a frame. This screen can be embossed with fine lines running in the same direction in a pattern, to resemble brushed silk.
