Method of electrographically manufacturing a luminescent screen assembly for a CRT and CRT comprising a luminescent screen assembly manufacturing by the method |
摘要 |
The method of electrophotographically manufacturing a screen on an interior surface of a faceplate for a CRT, according to the present invention comprises the steps of first-coating the faceplate with a volatilizable conductive layer, second-coating the conductive layer with the first photoconductive layer including a dye sensitive to ultraviolet rays, third-coating the ultraviolet-photoconductive layer with a second photoconductive layer including a dye sensitive to visible light, charging the whole area of the second photoconductive layer by exposing the whole surface of the second photoconductive layer to visible light while applying a suitable DC voltage between the conductive layer and the second photoconductive layer, and exposing selected areas of said first photoconductive layer to ultraviolet rays through a shadow mask to discharge the charge from the selected areas of the first photoconductive layer. Then, in developing a uniform density of the screen structure material is obtained.
