摘要 |
An electron gun for a color cathode ray tube includes cathode, control and screen electrodes, forming a triode. The electron gun includes first, second and third focus electrodes, forming main and auxiliary lenses. A final accelerating electrode faces the third focus electrode. A static voltage is applied to the screen electrode and the second focus electrode. A dynamic focus voltage is applied to the first and third focus electrodes. First and second quadrupole lenses are formed.
