Abstract
본 고안은 칼라 음극선관용 전자총을 개시한다.The present invention discloses an electron gun for a color cathode ray tube.
본 고안은 포커스 전극 또는 최종가속전극중 적어도 하나가 적, 청, 녹색의 새 전자빔이 통과하는 대구경전자빔 통과공이 형성된 외주전극과, 상기 외주전극의 가장자리로부터 소정깊이 인입된 위치에 설치되는 것으로 중앙의 전자빔을 감싸는 지지부와, 상기 지지부의 단부로부터 전자빔진행방향으로 소정길이 연장된 연장부를 가지는 단면 ??자형의 보조전극을 구비하여 된 것에 특징이 있으며 이는 주렌즈를 이루는 전자빔통과공이 실효직경을 확대시켜 주렌즈의 구면수차 또는 비점수차를 줄일수 있는 이점이 있다.According to the present invention, at least one of the focus electrode or the final acceleration electrode is installed at a position where a large diameter electron beam passing hole through which a new electron beam of red, blue, and green passes is formed, and a position deeply inserted from an edge of the outer electrode. It is characterized in that it has a support part surrounding the electron beam, and a cross-section? -Shaped auxiliary electrode having an extension part extending a predetermined length from the end of the support part in the direction of the electron beam progression. There is an advantage to reduce spherical aberration or astigmatism of the main lens.
