ABSTRACT:
A display device projects an image alternatively onto a remote surface and a rear projection screen. The display device has a base, a projector, a rear projection screen, and a mirrored surface. The projector is affixed to the base. The rear projection screen is mounted on the base. The housing extends rearward of the rear projection screen and has an opening formed therein. The mirrored surface is angled to reflect light from the projector onto the rear projection screen. The rear projection screen and the housing are pivotal on the base. In one position, the projector is exposed for projection onto the remote surface. In another position, the projector is engaged within the opening for projection through the opening at the mirrored surface.
