Abstract : The objectives of the Head-Up Display Technology Demonstration program were to demonstrate the feasibility of constructing liquid crystal matrix display modules with high optical performance and few defective elements, and of using optical projection techniques to combine the images from multiple, physically separate, display modules into a continuous high resolution display surface. Most of the original objectives of Head-Up Display Technology Demonstration program have been achieved or exceeded. Major improvements in display brightness and contrast have resulted from the development of improved matrix smoothing techniques and specular projection systems, and from the incorporation of low reflectivity transparent electrodes. The 60% reflectivity and greater than 30:1 contrast of the liquid crystal modules produced on this program are adequate to meet all known projection display requirements.
