Abstract:
An electron gun for a cathode-ray tube, comprisinga ti-electrode part having a control electrode and an accelerating electrode for configured to control an amount of electron beams emitted from a plurality of cathodes and to accelerate the electron beams; a front focusing lens part comprising a plurality of electrodes configured to focus and to accelerate the electron beams; and a main lens part comprising a plurality of electrodes configured to focus the electron beams on a screen, wherein a diameter of beam passage holes of the accelerating electrode of said ti-electrode part corresponds to approximately 140-220% of a diameter of beam passage holes of the control electrode, and wherein a distance between the control electrode and the accelerating electrode corresponds to approximately 40-80% of the beam passage hole diameter of the control electrode, and wherein a thickness of the control electrode corresponds to approximately 20-30% of the beam passage hole diameter of the control electrode.
