Abstract
An image display system includes a polarized image projection device, a polarization preserving transmissive diffusiver, and a polarizing reflector element as a non-blocking mirror (referred to as a 'combiner'). The combination of a polarization preserving transmissive diffuser or rear projection screen and a polarizing reflector results in a high brightness HUD for applications including automotive, aerospace, or other applications where HUD systems are used. The system also maintains the low haze and high transmittance of the windshield that will meet the requirement of standards of windshields for motor vehicles and similar applications.
