Abstract

본 발명은 칼라 음극선관용 전자총을 개시한다.The present invention discloses an electron gun for a color cathode ray tube.

본 발명은 전치 삼극부를 이루는 캐소오드, 제어전극 및 스크린 전극과, 주렌즈부를 이루는 복수개의 전극을 구비하여 된 칼라 음극선관용 전자총에 관한 것으로, 상기 주렌즈부가 적어도 5개 이상의 사중극렌즈를 포함하는 것에 특징이 있으며, 이는 전자빔이 편향요오크의 불균일한 자계에 의해 왜곡되는 것을 보상할 수 있는 이점을 가진다.The present invention relates to a cathode for a color cathode ray tube comprising a cathode, a control electrode, and a screen electrode forming a transposition triode, and a plurality of electrodes forming a main lens, wherein the main lens comprises at least five quadrupole lenses. This feature is advantageous in that the electron beam can be compensated for being distorted by the nonuniform magnetic field of the deflection yoke.
