  • Humidity and temperature insensitive organic conductor for electrophotographic screening process
    Patent number: 6326110
    Abstract: In accordance with the present invention, a method of electrophotographically manufacturing a luminescent screen assembly on an interior surface of a faceplate panel 17 of a color CRT 10 includes the steps of: coating the surface of the panel with a conductive solution to form a volatilizable organic conductive layer 32, and overcoating the organic conductive layer 32 with a photoconductive solution to form a volatilizable photoconductive layer 34. The conductive solution comprises the organic polymer 3,4-polyethylene dioxythiophene polystyrene sulphonate (PEDT/PSS); a methanol-soluble polymer or co-polymer selected from the group consisting of polyvinylpyrrolidone (PVP), poly (vinyl pyridine-co-vinyl acetate) (PVPy-VAc), polymethacrylic acid (PMAA), poly (hydroxyethylacrylate-co-methacrylic acid) (PHEA-MAA) and poly (hydroxyethyl methacrylate) (PHEMA) to reduce organic residue; and a solvent.
