ABSTRACT:
The invention comprises a multiple rear projection screen assembly which includes a plurality of rear projection screens and framing members between adjacent screens. Each screen has edges and a front and rear side, and are positioned in an adjacent relationship to form a contiguous viewing area such that each screen has at least one edge abutting the edge of an adjacent screen. Framing members are disposed along abutting edges of the screens with at least one of the framing members including a front bracket located along the front side of the abutting edges of two screens, and a rear bracket located along the rear side of the abutting edges of the two screens. The front bracket is spaced from the rear bracket and a fastener passes between the abutting edges of the screens. The fastener fastens the front bracket to the rear bracket such that the abutting edges of rear projection screens are simultaneously compressed between the front and rear brackets.
