Patent number: 6394609Abstract: A front projection display system that integrates an optical engine, having control and power supply electronics, and a dedicated projection screen to provide a compact video display device. The projection engine is coupled to a high gain projection screen, having an optimized reflection pattern to give optimum optical performance in ambient H& and viewing angle sensitive environments. Components of the projection engine are modularly placed in a retractable arm pivotally connected to the screen. The arm offers precise registration to the screen apparatus and thus repeatably precisely aligns optically and mechanically to the screen. The projection wall system has an open projection position and a closed storage position. Use of a radically offset projection head having matching keystone correction features allows the arm to protrude above the head of the presenter and offer a sharp and unobtrusive projection zone.Type: GrantFiled: July 14, 2000Date of Patent: May 28, 2002Assignee: 3M Innovative Properties CompanyInventors: Ernesto M. Rodriguez, Jr., Dennis F. Vanderwerf
