PURPOSE:To eliminate the need for the conventional exposure, development, and etching process, remove materials that generate pollution, and increase productivity by forming a film-type phosphor, pressing and bonding the phosphor on the funnel section of a cathode-ray tube with the use of a heat element. CONSTITUTION:A phosphor 9 is applied to form a film with constant thicknesses on one surface of a film 8, such as paper and plastic. On the other hand, the inner surface of the funnel section 10 of a color cathode-ray tube is coated with a pretreatment coat 11. Besides, a heat element 12 that is integratedly provided with a number of protrusions 13 to be coated with the phosphor 9 is provided and the film 8 is positioned on a surface coated with the pretreatment film 11 of the funnel section 10. The heat element 12 is moved downward and is heated by applying current to a heater 14. The film 8 and the phosphor 9 are pressed by the protrusions 13 and the pretreatment coat 11 is dissolved by the heat of the protrusions 13 and then the phosphor 9 is bonded with the pretreatment coat 11 only at the protrusions 13. |
