Patent ID: 6952077

Claim:
An electron gun for a cathode ray tube, comprising: a cathode for radiating electron beams; a scanning velocity modulation coil for synchronizing the electron beams with an image signal; a focus electrode including first and second sub-electrodes disposed with a gap through which a magnetic field generated by the scanning velocity modulation coil passes; a plurality of grid electrodes with said focus electrode for controlling the electron beams radiated from said cathode; a support for aligning and supporting said grid electrodes; and a shield electrode electrically connected to said first and second sub-electrodes to protect from infiltration of an outer electric field, said shield electrode comprising plural intermediate electrodes disposed in the gap between said first and second sub-electrodes and electrical connecting means for electrically connecting said intermediate electrodes to said first and second sub-electrodes, said intermediate electrodes being spaced away from each other and having different thickness from each other.
