| titleOfInvention | Color cathode-ray tube apparatus |
| abstract | A color cathode ray tube apparatus of this invention includes an electron gun with an intermediate electrode 13-2, which is arranged at the mechanical center between a focus electrode 11 and anode electrode 12 of a rotationally symmetric bi-potential lens; and a disk-like intermediate electrode 13-1, which is arranged at the mechanical center between the focus electrode 11 and intermediate electrode 13-2. The disk-like intermediate electrode 13-1 has electron beam holes with a diameter larger in the vertical direction than in the horizontal direction. The intermediate electrode 13-2 has circular electron beam holes. Voltages are applied to the disk-like intermediate electrode 13-1 and intermediate electrode 13-2 such that they form an electron lens similar to that formed when the disk-like intermediate electrode 13-1 does not exist. Therefore, an electron beam spot is focused in an optimal manner on the entire surface of a phosphor screen, and elliptic distortion is decreased. A good image is displayed on the entire surface of the phosphor screen. |
