ABSTRACT:
A pixel compensated electro-optical display system utilizing a pixel compensator to correct image problems. The pixel compensator comprises pixels having elongated geometric shapes that compensate for distortions normally occurring in optical systems utilizing one or more reflective surfaces. The pixels are configured so that when the image plane is viewed at a particular angle, the image is substantially corrected without complex optical refiguring. The pixel compensated electro-optical display system of the present invention accordingly minimizes the need to correct the reflected image. The optical system of the present invention finds utility in applications that require a reflected image because of spatial and other constrictions. The optical system of the present invention finds particular application in vehicle "heads up" display systems as well as in virtual reality and total immersion display systems.
