Abstract

본 발명은 칼라 음극선관용 전자총을 개시한다. 본 발명은 삼극부를 이루는 캐소오드, 제어전극 및 스크린전극과 주렌즈계를 이루는 복수개의 포커스 전극 및 최종가속전극과, 상기 포커스 전극 또는 최종가속전극에 설치되어 전자빔의 단면을 보정하는 사극자 부재를 구비하여된 칼라 음극선관용 전자총에 관한 것으로, 상기 사극자 부재가 중앙의 전자빔 통과공과 대응되는 축의 길이와 양측 전자빔과 대응되는 축의 길이가 상호 다르게 형성된 것에 특징이 있으며, 이는 세전자빔의 포커스 특성을 향상시킬 수 있는 이점을 가진다.The present invention discloses an electron gun for a color cathode ray tube. The present invention includes a cathode, a control electrode, a screen electrode, a plurality of focus electrodes and a final acceleration electrode forming a main lens system, and a quadrupole member installed on the focus electrode or the final acceleration electrode to correct a cross section of an electron beam. The quadrupole member is characterized in that the length of the axis corresponding to the electron beam passing hole in the center and the length of the axis corresponding to both electron beams are formed different from each other, which improves the focusing characteristics of the three-electron beam. Has the advantage.
