ABSTRACT:
In accordance with the present invention, a method of electro-photographically manufacturing a luminescent screen assembly on an interior surface of a faceplate panel 12 for a color CRT 10 includes the steps of coating the interior surface of the faceplate panel with a volatilizable, organic conductive solution to form an organic conductive (OC) layer 32, and overcoating the OC layer with a volatilizable, organic photoconductive solution to form an organic photoconductive (OPC) layer 34. The step of overcoating the OC layer to form the OPC layer is improved by the substeps of: grounding the OC layer; providing an organic photoconductive (OPC) solution comprising a resin, an electron donor material and electron acceptor material, and a suitable solvent; and spraying electrostatically-charged droplets of the OPC solution onto the OC layer, with at least one electrostatic spray gun 47, to provide an OPC layer, having uniform thickness, overlying the OC layer.
