Abstract
A collapsible projection backwall system utilizes a short throw projector and a collapsible framework to create a display usable in a small amount of space. The framework is specifically configured to support and appropriately position a flexible screen member so that distortion is avoided. This is particularly significant in situations where a relatively large screen is utilized, which creates the need to maintain appropriate tension upon the flexible screen member. The framework is specifically configured to be slightly canted when in its extended configuration to thereby introduce natural tension forces which will cooperate with the screen fabric to maintain the necessary configuration for the screen. This canted configuration is achieved by configuring a set of corner hinge assemblies and any central hinged assemblies to maintain this natural cant. By maintaining the desired forces on the display screen fabric a more efficient and functional display screen is created.
