ABSTRACT:
An image projection system utilizing a cold cathode field emission device to provide the image source is provided. By using a cold cathode field emission device as an image source, an improved image may be achieved as compared to that of a conventional electron-gun CRT image source. First, the resulting image provides improved resolution, due to the fact that smaller pixel cells may be achieved with the cold cathode device. Second, the resulting image is considerably brighter, due to the fact that much higher current densities are achievable with a cold cathode image unit, as compared to the older electron-gun CRT unit.
