Summary:A collapsible, large screen audiovisual display system is provided. The preferred embodiment of the invention includes a square-shaped, forwardly mounted projection screen bordered by a protective framework. The screen is connected to a rearwardly placed, square-shaped, support frame by extendable scissor arms. A flexible drape extends between the screen and rear support frame and is internally supported by a plurality of guy wires. Each guy wire is connected at a first end to a recoiling reel and at a second end to the periphery of the screen and passes through a plurality of grommets positioned on the inside of the drape. The invention is equipped with wheels to aid in setup and transportation, the wheels being affixed to telescoping screw lifters such that the height of the screen and rear support frame is variable. A video projector and sound system are housed within the rear support frame.
