PURPOSE:To improve the voltage resistance property, and to absorb the discharging energy, by providing means for increasing the dynamic resistance and means for reducing th dynamic resistance. CONSTITUTION:The inner conductive films are coated on a conductor 11 at the side of fluorescent screen, a conductive film 12 at the side of electron gun and an intermediate conductive film 13 while adjoining each other, where the dynamic resistance of the latter is set higher than those for the former two. When applying high voltage on an anode button the dynamic resistance can be reduced, thereby sufficient conditioning process can be performed. When mounting thus processed cathode-ray tube on a display, high voltage is applied on the anode button 31 while the anode button 32 is provided with proper cover and opened. Since the dynamic resistance from the anode button 31 to the anode 4 of the electron gun is high, the discharging energy is absorbed effectively by the inner conductive film. |
