  • Formation Of Various Coating Films On Cathode Ray Tubes And Lamps (AREA)

Abstract

PURPOSE: To manufacture a cathode-ray tube by forming an intermediate film on a fluorescent material layer by spraying and then by stacking a conductive and reflective layer.
CONSTITUTION: On one surface of skirt-less surface panel 1, fluorescent-substance layer 4 resides and seal area 7 is covered with flange 11 of mask 10. While the panel is rotated, lacquer 22 is sprayed upward from nozzle 21. While flying, almost all toluene in lacquer 22 vapors up and acrylic resin arrives at the surface of panel 1 flows and dries on layer 4, thereby generating a uniform intermediate film. At this time, since its fluidity is small, the need of conventional airtight masking is eliminated and the operation is simplified. When the intermediate film almost becomes dry, Al is vapor-deposited uniformly on uniform layer 4 without stain or spot and heat-treated to decompose and remove the intermediate film and organic binder, thereby making only Al remain on layer 4. In this constitution, the masking of the seal area is simplified and a drying process is not required, so that the operation will improve
