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, 스크린 전극으로부터 순차적으로 설치되며 사이에서 전자빔의 크로스 오버점이 형성되도록 제1보조렌즈를 이루어지는 적어도 두개 이상의 제1포커스 전극군 및 제2보조렌즈를 이루는 적어도 두개의 제2포커스 전극군과, 제2포커스 렌즈군과 인접되게 설치되어 주렌즈를 이루는 최종가속전극을 구비하여 된 것에 그 특징이 있으며, 이는 렌즈의 구면수차를 줄여 전형 광면에서 균일한 전자빔 스포트를 얻을 수 있는 이점을 가진다.According to the present invention, at least two first focusing electrode groups and a second at least one first auxiliary lens including a cathode, a control electrode, and a screen electrode constituting the transposition triode and a first auxiliary lens are sequentially provided from the screen electrode, and a crossover point of the electron beam is formed therebetween. At least two second focus electrode groups constituting the auxiliary lens and a final accelerating electrode disposed adjacent to the second focus lens group to form the main lens are characterized by reducing spherical aberration of the lens, thereby reducing the typical optical surface. Has the advantage of obtaining a uniform electron beam spot at.
