发明名称 Display device for projecting an image alternatively onto remote surface and a rear projection screen
摘要 A display device (2) projects an image alternatively onto a remote surface (4) and a rear projection screen (6). The display device (2) has a base (14), a projector (12), a rear projection screen (6), and a mirrored surface (10). The projector (12) is affixed to the base (14). The rear projection screen (6) is mounted on the base (14). The housing (8) extends rearward of the rear projection screen (6) and has an opening (16) formed therein. The mirrored surface (10) is angled to reflect light from the projector (12) onto the rear projection screen (6). The rear projection screen (6) and the housing (8) are pivotal on the base (14). In one position, the projector (12) is exposed for projection onto the remote surface (4). In another position, the projector (12) is engaged within the opening (16) for projection through the opening (16) at the mirrored surface (10). <IMAGE>
