摘要:
In a method of fabricating a cathode-ray tube, an evacuated and sealed bulb provided with a phosphor screen and an electron gun including a cathode is subjected to a process of flashing a getter attached to the inner wall of the bulb. Thereafter, the bulb is subjected to a scanning process of causing the electron gun to emit an electron beam therefrom while deflecting the electron beam. The scanning process is followed by an aging process for the cathode of the electron gun.
