Abstract

There are many technical approaches to replacement of the CRT image source for a Head-Up Display (HUD). LCD projectors promise to greatly lower the cost of the HUD because the cost of these displays continues to drop while the cost of CRTs remains stable. LCD projectors allow the realization of multi-colors in the HUD. Their high luminance provides bright raster images, where CRTs are limited by the constraints of the scanning electron beam. Finally, LCD projectors have a digital interface. There are none of the high voltage power supplies, A/D converters, and deflection amplifiers found in CRT drive systems, further improving cost and reliability. This paper describes the performance requirements and achieved performance of an LCD projection image source for use in a wide field of view head-up display (HUD) optical system.
