ABSTRACT:
The method of electrophotographically manufacturing a screen assembly on a substrate for use within a CRT, according to the present invention, includes the steps of sequentially coating a substrate with a conductive layer and an overcoating of a photoconductive layer, establishing an electrostatic charge on the photoconductive layer, and exposing selected areas of the photoconductive layer to visible light to affect the charge thereon. Then the photoconductive layer is developed with a charged screen structure material. The improved process utilizes a dry-powdered screen structure material having at least a surface charge control agent thereon to control the triboelectrical charging of the screen structure material.
