摘要： The method of surface-treating dry-powdered phosphor particles for use in manufacturing a luminescent viewing screen (22) for a CRT (10), to control triboelectric charge characteristics of the phosphor particles, includes the steps of dissolving a suitable quantity of a polymeric coupling agent in a suitable solvent to form a mixture, surface-treating the phosphor particles by adding them to the mixture to provide a coating of the coupling agent thereon, and then drying the surface-treated phosphor particles. The resultant dry-powdered surface-treated phosphor particles are used to make the screen. The coupling agent controls the triboelectric charge characteristics of the phosphor particles during the electrophotographic manufacturing of the screen.

摘要： The method of electrophotographically manufacturing a screen assembly (22) on a substrate (18) for use within a CRT (10), according to the present invention, includes the steps of sequentially coating a substrate with a conductive layer (32) and an overcoating of a photoconductive layer (34), 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 triboelectrical charging of the screen structure material.
