1. A light projection visual display system for use in simulation that replaces an existing cathode-ray tube visual display system that is lightweight and low cost while eliminating cross-talk interference previously existing with cathode-ray tube display systems comprising: a lamp light source; means for controlling light projected from said lamp for generating an image containing information; means for providing a digital informational signal to said means for controlling said light; back projection screen sized in area to fit and replace the screen area of the cathode-ray tube display system being replaced; lens-array disposed between said back projection screen and said light control image-generating means for image modification; whereby said lamp light source, said light control means, said screen and said lens-array are all mounted together in the space originally occupied by the cathode-ray tube system being replaced.
