ABSTRACT:
A multiple color display system employing a high speed display panel adapted for positioning on a conventional photographic projector for displaying large video images. The high speed display panel is coupled to an interface unit for converting conventional NTSC signals into analog signals for driving a controller employing a modulation or duty cycle circuit coupled between the high speed display panel and a memory which is drive by the interface unit. The controller also employs a scan modulator for formatting the NTSC signal so that it may be displayed on a 640 by 480 matrix array employed by the high speed display device. Such a system is modular and employs relatively inexpensive subassembly units such as a user selected television signal generating type device, such as a video cassette recorder, a conventional photographic projector and screen, a high speed color enhancing interface controller and a high speed display device, such as an active matrix display panel adapted for positioning on the stage of the projector.
