ABSTRACT:
In a method of coating a curved panel in a cathode ray tube, by placing on the inner surface of a panel having a curved surface a screen frame of a boat-shaped configuration across the bottom of which a screen printing screen is stretched; and by moving a squeegee pushed against the surface of the screen so that ink coated on the surface of the screen passes through the screen and prints on the inner surface of the panel, a fluorescent screen having a good and even film is fabricated on the inner surface of the cathode ray tube panel having a curved face, by a screen printing. In the method, electro-conductive terminals for electro-deposition are not required, steps are reduced, production costs are reduced, and production quality is stabilized.
