Abstract:

The patent relates to a dual phosphor screen deposited on the inside surface of the faceplate of a CRT. A photo electroluminescent panel made up of a layer of photoconductive material and a layer of electroluminescent material is placed on the outside surface of the CRT. A voltage is applied across the panel so that when ultraviolet energy illuminates the photoconductive material, the voltage change across the panel causes the electroluminescent material to be visible.
