Electron gun with electron beam converging member disposed between quadrupole and main lens and a cathode ray tube employing the same

A cathode ray tube comprising electron beams emitted from an electron gun so as to selectively strike a three-color phosphor screen, wherein said electron gun comprises:

• an electron beam emitter for emitting three electron beams;
• a quadrupole lens;
• high voltage electrodes forming a main lens, and
• an a cup shaped electron beam orienting means disposed between said quadrupole lens and said main lens which orients two side electron beams toward a center electron beam so that said three electron beams emitted from said emitter cross in said main lens.

An electron gun for a color cathode ray tube, comprising:

• an electron beam emitter for emitting three electron beams;
• a quadrupole lens through which said electron beams are passed;
• high voltage electrodes forming a main lens through which said electron beams are passed;
• and
• a cup shaped conductive member disposed between said quadrupole lens and said main lens for converging said electron beams so that said electron beams cross in said main lens.
