Abstract

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

본 발명은 대구경전자빔통과공이 형성된 제1 전극과 상기 제2 전극의 가장자리로부터 소정길이 인입되도록 제1 전극내에 설치되며 세개의 독립 소구경전자빔통과공이 형성된 제2 전극으로 이루어진 최종가속전극에 있어서 상기 제1 전극으 단부와 제2 전극 사이에 보조전극편을 설치하여 된 것에 특징이 있으며 이는 메인렌즈의 구면수차를 개선하여 이를 채용한 음극선관의 해상도를 향상시킬수 이점을 가진다.The present invention relates to a final acceleration electrode including a first electrode formed with a large diameter electron beam passing hole and a second electrode provided with three independent small diameter electron beam passing holes formed in the first electrode to draw a predetermined length from an edge of the second electrode. It is characterized in that the auxiliary electrode piece is provided between the end of the first electrode and the second electrode, which has the advantage of improving the spherical aberration of the main lens to improve the resolution of the cathode ray tube employing it.
