Abstract: An inflatable display system with a projection screen on two opposing sides is provided that allows a single inflatable display support to allow viewers to watch the screens on both sides, thereby doubling the number of viewers per inflatable display support without increasing the size of the display support. An opaque material may be placed between the projection screens or integrated into the back of the screens to avoid interference from light from images projected from the opposite side. In this way, a screen operator or user can accommodate viewers on both sides of the display system, essentially doubling viewer capacity without having to set up two inflatable supports or increase the size of the screen/support system.
