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.
