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 스크린전극과, 보조 및 주렌즈계를 이루는 제1,2,3,4포커스 전극과 최종가속전극을 구비하여 된 칼라 음극선관용 전자총에 관한 것으로, 상기 제2포커스전극의 출사측면과 상기 제3포커스 전극의 입사측면에 전자빔의 편향시 전자빔의 회전 뒤틀림에 의한 전자빔단면의 왜곡을 방지하는 전자빔 왜곡보상수단이 마련된 것에 특징이 있으며, 이는 편향수차에 전자빔의 왜곡을 보상할 수 있는 잇점을 가진다.The present invention relates to an electron gun for a color cathode ray tube comprising a cathode, a control electrode, and a screen electrode forming an anterior triode, and first, second, third, and four focus electrodes and an final acceleration electrode forming an auxiliary and main lens system. The electron beam distortion compensation means is provided on the exit side of the second focus electrode and the incident side of the third focus electrode to prevent distortion of the electron beam cross section due to the rotational distortion of the electron beam when the electron beam is deflected. It has the advantage of compensating for distortion.
