    摘要： In accordance with the present invention, a method of electrophotographically manufacturing a luminescent screen assembly for a color CRT 10 on an interior surface of a faceplate panel 12 is described. A volatilizable organic conductive (OC) layer 32 is provided on the interior surface of the panel and a volatilizable organic photoconductive (OPC) layer 34 overlies the OC layer 32. The method includes the steps of: establishing a substantially uniform electrostatic charge on the OPC layer; exposing selected areas of the OPC layer to visible light to affect the charge thereon; developing the selected areas of the OPC layer with a triboelectrically charged, dry-powdered, first color-emitting phosphor; sequentially repeating the charging, exposing and developing sequence for triboelectrically charged, dry-powdered, second and third color-emitting phosphors to form a luminescent screen comprising picture elements of triads of color-emitting phosphors; fixing the phosphors to the underlying OPC layer with a suitable fixative; filming the phosphors; and aluminizing the filmed phosphors. The present method is an improvement over prior methods because the fixing step utilizes an electrostatic spray to uniformly contact the phosphors and the underlying OPC layer with the fixative, without moving the phosphors.

    摘要： A method of manufacturing a luminescent screen assembly on an interior surface of a faceplate panel 12 for a color CRT 10 includes the steps of uniformly applying a solution of a material to form an organic conductive (OC) layer and overcoating the OC layer with a solution to form an organic photoconductive (OPC) layer, on the interior surface of the faceplate panel. The OPC layer 34 is conditioned by directing a stream of dry gas thereon to warm the OPC layer to a preheat temperature, while maintaining the panel at a panel temperature less than the preheat temperature. The OPC layer is exposed to IR radiation to rapidly increase the temperature of the OPC layer to a curing temperature, greater than the preheat temperature, to remove some of the volatilizable constituents from the OPC layer, without substantially increasing the temperature of the panel. The OPC layer is then cooled by directing at least one stream of cool gas onto the surface thereof, to lower the temperature of the OPC layer to a subsequent processing temperature.

    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.
