Color cathode ray tube having improved main lens electrodes |
摘要 |
A color cathode ray tube includes a phosphor screen, a shadow mask closely spaced from the phosphor screen and an electron gun. The electron gun includes three cathodes for emitting three in-line electron beams and a plurality of electrodes each having electron beam apertures for passing the electron beams, the electrodes are fixed in a predetermined axially spaced relationship on insulating supports, at least one of the electrodes is cup-shaped and has a correction plate electrode therein welded thereto, and edges of the correction plate electrode are formed with recesses and have sloped portions extending in a direction away from the recesses toward an inner wall of the electrode containing the correction plate electrode.
