Abstract
The cold-air inflatable portable projection screen has two inflatable towers that are connected by an inflatable tube or cross member. A fine mesh material may be suspended between the two towers to form a projection screen. Tethers connected to the towers serve to anchor the structure to the ground. Electric blowers or fans continuously blow air into the structure to keep it erect.
