    Abstract: PROBLEM TO BE SOLVED: To provide an electrophotographic screening method manufacturing a uniform luminescent screen by providing a substantially uniform OPC layer during 8 seconds or less.
    SOLUTION: The manufacturing method of a luminescent screen assembly includes a step overcoating an interior surface of a faceplate for forming a volatile organic conductive (OC) layer, and a step coating the OC layer for forming a volatile organic photoconductive (OPC) layer. The step of overcoating the OC layer is improved by grounding the OC layer, providing an OPC solution comprising a resin, an electron donor material, an electron acceptor material, and a mixture of two solvents having different boiling points, and spraying electrostatically-charged droplets of the OPC solution onto the OC layer, with at least one electrostatic spray gun, to provide an OPC layer, having uniform thickness, overlying the OC layer.

    Abstract: 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.

    Abstract: An apparatus (200) for developing a latent image formed on a photoreceptor, which is deposited on an interior surface of a faceplate panel (12) of a CRT display device (10), is disclosed. The developing apparatus includes a developing chamber (202), having a support surface (204) for supporting the panel, a screen structure material reservoir (222) for storing, deagglomerating and feeding the screen structure material (226), and a triboelectric gun assembly (236) communicating with the reservoir. The gun assembly triboelectric charges and imparts a desired charge polarity to the screen structure material. The gun assembly further includes at least one material dispersing nozzle (238) spaced from the support surface, for distributing the charged material for deposition onto the latent image.
