ABSTRACT:
A rear projection screen assembly including a plurality of rear projection screen panels and a framing system for interconnecting the panels. Each of the panels includes an audience facing front surface and a rear surface upon which an image is projected. Selected perimeter edges of the panels include notches which are in registry with notches provided on the perimeter edges of adjacent panels when the panels are arranged in a screen-forming relationship. The framing system includes front brackets and rear brackets disposed along the notched edges of the panels at the panel front surfaces and rear surfaces respectively. Fasteners which extend through the notches in the panel edges connect the front bracket to the rear bracket such that the panels are secured between the brackets. The invention also provides an integrally formed fastener and bracket to facilitate assembly.
