An inflatable movie screen is an inflatable framework with an attached projection screen. Inflatable screens are used for outdoor movies, film festivals, drive-in theaters, sports, social, fundraising and other events requiring outdoor projection.

Design[edit]

The projection frame is made from PVC coated fabric layers joined by high frequency welding or mechanical sewing. The projection surface can be made of PVC or spandex, with the latter providing for rear projection capabilities. The projection surface can be detachable for ease of care. The frame is inflated with a high pressure air blower. Larger frames may require a three phase blower. For bigger screens, the blower typically continues to operate, ensuring the screen remains fully inflated. For consumer market and smaller screen sizes, the screen is sealed and does not require a constantly operating air blower.

Screens can be held upright with help of a supporting structure (A-frame or inflatable legs) or with the system of straps and counter weights.

In comparison to traditional and heavy steel constructions, inflatable screens can be set up only a few hours with the smallest screens taking one minute to inflate. This can be useful for environments where wind may be a factor. Inflatable screens can be deflated quickly adding to their safety. Inflatable screens are lightweight and highly portable compared to other structures used to support screens like a truss or scaffold. A 52'/16m wide screen usually fits on a single pallet. A truss or steel system takes up an entire truck. Inflatable screens reach sizes up to 6,000 square feet (560 m2).[1]
