Abstract:
A method of manufacturing a cathode-ray tube having a process of forming a phosphor screen, the process comprising:an application process in which a phosphor slurry is injected onto an inner face of a glass panel and the glass panel is tilted with respect to a vertical axis and is rotated to spread the phosphor slurry over almost an entire area of the inner face of the glass panel;a shake-off process in which by rotating the glass panel with a tilt, excess phosphor slurry is shaken off, and the phosphor slurry is recovered in phosphor-slurry recovery members provided at corners of the glass panel; anda drying process in which by rotating the glass panel with a tilt, the phosphor slurry applied onto the inner face of the glass panel is dried,wherein the application process comprises:a first application step in which the glass panel is rotated at a predetermined tilt angle and a predetermined rotation speed;a second application step subsequent to the first application step in which the glass panel is rotated at a wider tilt angle than that in the first application step and a lower rotation speed than that in the first application step; anda third application step subsequent to the second application step in which the glass panel is rotated at a lower rotation speed than that in the second application step.
