Title: INTEGRATED FRONT PROJECTION SYSTEMAbstractA front projection display system that integrates an optical engine, having control and power supply electronics, and a dedi cated projection screen to provide a com pact video display device. The projection engine is coupled to a high gain projection screen, having an optimized reflection pat tern to give optimum optical performance in ambient light and viewing angle sensi tive environments. Components of the pro jection 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 off set projection head having matching key stone correction features allow the arm to protrude above the head of the presenter and offer a sharp and unobtrusive projec tion zone.
