    摘要： The method of surface-treating dry-powdered phosphor particles for use in manufacturing a viewing screen for a CRT to control the 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 a luminescent viewing screen for a CRT. 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 on an interior surface of a faceplate panel for a color CRT, according to the present invention includes the step of forming a photoreceptor by sequentially coating the surface of the panel with a conductive solution to form a volatilizable conductive layer and then overcoating the conductive layer with an organic photoconductive solution comprising a suitable resin, an electron donor material, an electron acceptor material, a surfactant and an organic solvent to form a volatilizable photoconductive layer. The photoconductive layer of the photoreceptor is resistant to cracking during filming, displays increased phosphor adherence during fixing, can be substantially completely baked-out, and has substantially no spectral sensitivity beyond 550 nm so that the screening process may be carried out in yellow light, rather than in the dark, in order to provide a safe working environment without deleterious effects on the panels coated with the novel photoconductive layer.

    摘要： A method of surface-treating dry-powdered phosphor particles to control the triboelectric charge characteristics thereof includes the steps of providing the phosphor particles with a first coating of silica, dissolving a coupling agent selected from the group consisting of silanes and titanates in a suitable solvent to form a mixture, surface-coating the silica-coated phosphor particles with the mixture to provide a second coating of the coupling agent on the phosphor particles, filtering the surface-treated particles, rinsing the surface-treated particles with the solvent, and drying the surface-treated particles. The resultant dry-powdered surface-treated phosphor particles are used to make a luminescent viewing screen for a CRT. The coupling agent overlying the silica coating controls the triboelectric charging characteristics of the phosphor particles during the electrophotographic manufacturing of the screen.
