Fixing Solvent for Fixing Process of Dry Electro Photographic Screen of Cathode Ray Tube, Method of Manufacturing Screen of Cathode Ray Tube Using the Fixing Solvent, and Cathode Ray Tube

摘要

The present invention provides a fixing solvent for a fixing process in the production of a dry electrophotographic screen of a cathode ray tube.;The fixing solvent is formed by forming a volatile photoconductive film 134 containing a substance sensitive to visible light or ultraviolet rays on a volatile conductive film 132 coated on the inner surface of a panel 12 and forming a uniform static charge on the photoconductive film 132 After charging, the photovoltaic layer is selectively exposed to visible light or ultraviolet light from a visible light or ultraviolet light source through a shadow mask, and at least one phosphor (R, G, B) After the fine powders of the substance 21 are adhered, the solvent is sprayed on the surface of the photoconductive film 134 to which the fine powder (s) are adhered in a desired arrangement by a vapor deposition method or an electrostatic spraying method, A fixing solvent for a fixing process for the production of a dry electrophotographic screen of a cathode ray tube for fixing fine powder (s) on a substrate, comprising: Ketone, and a petroleum-based xylene (xylene), toluene (toluene), TCE, characterized in that inorganic particles are formed they are added as a mixed solvent of two or more of solvents such as methyl isobutyl ketone (MIBK).;As a result, many irregularities are formed on the surface of the photoconductive film 134 by the inorganic particles, thereby improving the adhesion of the aluminum thin film layer and completely volatilizing the volatile components such as the photoconductive film, thereby greatly improving the mirror surface of the aluminum thin film layer .
