Abstract

A front projection screen, which produces a realistic color temperature correct image with depth of field; whilst masking the pixilation produced by the projector; to produce a smooth realistic high quality image. In a preferred form of the invention, the projection screen for front projection which forms the subject of this invention comprises a rigid substrate on which is provided a reflective, mirrored surface (12). Adjacent to this surface is a transparent layer (13); alternatively a laminated or cast transparent layer is applied to the reflective surface. Adjacent to this surface is a translucent layer (14), alternatively a laminated translucent film is applied to the transparent surface, and other layers may clearly be added to the composition of the screen and or elements embodied within the various layers to correct the colour or image or affect its optical properties or to facilitate manufacture.
