Zusammenfassung:	A heads-up display system suitable for use in a vehicle. The system includes a projector configured to project a projected image. A faceted reflector is included to overlay a dashboard area of the vehicle and define an array of reflective facets. Each facet is configured to reflect cooperatively a portion of the projected image to form a reflected image directed toward a windshield of the vehicle. A light diffusive layer is included to diffuse the reflected portion of the projected image such that the reflected image can be seen by an occupant of the vehicle as a reflection in the windshield. A light control film interposed between the windshield and the faceted reflector is included to propagate preferentially the projected image and thereby reduce the occurrence of ambient light washout of the reflected image being displayed.
