Abstract
A system for projecting changeable electronic content, such as video or digital still images, onto a curved surface. The system includes a housing, a reflector within the housing, and a projector. The housing has an exterior surface and an interior space. At least a portion of the exterior surface is a curved display surface capable of displaying electronic content projected upon it, and at least one portion of the exterior surface has an aperture through the exterior surface to the interior space. The projector is located proximate the aperture for projecting content through the aperture to the reflector. When the projector receives converted content and projects the converted content through the aperture to the reflector, the curved display surface displays the converted content undistorted to a viewer. The system can also provide for display of branded content on a product container having a shape corresponding with the brand.
