摘要： A method for manufacturing a color cathode ray tube, and in particular, for conditioning the surface of a panel of a color cathode ray tube to prepare it for the application of a pattern of color phosphors while minimizing the effects of reflections from interfaces in the panel. The method consists of coating a reciprocity-failing photoresist layer on the inner surface of the panel, drying the layer with a stream of low dew point air, exposing the layer to actinic radiation through a patterned mask to provide insoluble polymerized areas in preselected portions of the layer, developing the layer with a developing solution to remove unpolymerized areas while leaving the polmerized areas, applying an aqueous suspension of light absorptive material to the panel to replace the developing solution with the light absorptive material, drying the light absorptive material, applying an oxidizing solution to the panel to cause the polymerized areas to become water soluble, and removing the polymerized areas and the light absorptive material before applying the phosphors.

摘要： A method for manufacturing a metallic, luminescent screen for a CRT includes the steps of: depositing at least one phosphor layer on an inner surface of a faceplate of a panel, to form the luminescent screen; preheating the panel containing the screen to a temperature in excess of a minimum film-forming temperature; and depositing an aqueous emulsion of at least one acrylic film-forming resin onto a screen and drying said emulsion to form the film. Then, a metallic coating is deposited onto the film and the panel bearing the metallized screen is sealed to a funnel by heating the panel and funnel through a sealing cycle. The sealing cycle has predetermined rates of temperature increase and includes a temperature range within which the film is volatilized. The rate of temperature increase within the volatilization range is less than the rate of temperature increase in other portions of the sealing cycle.

摘要： The invention relates to a method for manufacturing a phosphor screen on an inner surface of a CRT panel, having a faceplate, a blend radius, and a sidewall. The method includes the steps of depositing at least one phosphor layer (R, G, B), containing a binder, on the inner surface of the faceplate, and then coating the phosphor layer, the blend radius, and at least a portion of the sidewall with a filming material. The coating of the filming material is dried to form a film. The film, or at least that portion thereof overlying the blend radius and the side wall, is contacted with an adhesion-promoting, blister-reducing solution which contains operable quantities of silica particles, a low vapor pressure alcohol and deionized water. A metal layer is deposited on the film, and the film and the binder contained in the phosphor layer are volatilized.

摘要： The present invention relates to a method for making a viewing screen structure for a cathode-ray tube. The method includes the steps of coating a support surface with a film of a polymeric material, a suitable dichromate and a sensitizer therefor which is a chromium ion migration enhancer having a reduced sensitivity to thermal and dark hardening; exposing the film to an image in the form of radiant energy until the solubility of the irradiated regions thereof is selectively altered, thereby producing in the film regions of greater solubility and regions of lesser solubility; removing those regions of the film with greater solubility to bare portions of the underlying support surface while retaining those regions of the film with lesser solubility. The bare portions of the support surface and the retained film regions are overcoated with a composition of light-absorbing material which is adherent to the support surface. A solution of an oxidant is applied to the light absorbing material to selectively dissolve the retained film regions. The dissolved retained film regions and the light-absorbing material thereon are flushed-away leaving the light-absorbing material adhering to the support surface. Following the above-described steps, a luminescent screen is formed by depositing phosphor materials on areas of the support surface previously occupied by the retained film regions.
