Abstract

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

본 발명은 전치 삼극관부와, 유리포텐셜형 정전렌즈를 이루는 세개의 포커스전극이 포함되어 된 칼라 음극선관용 전자총에 관한 것으로 상기 유니포텐셜형 정전렌즈를 이루는 세개의 포커스전극중 중앙의 포커스전극이 상기 삼극관부측으로 부터 종장형의 전자빔통과공이 형성된 제1전극과, 상기 제1전극이 종장형전자빔통과공 상하부에 삽입된 블레이드를 가지는 제2전극으로 분리되며,상기 제 1,2전극에는 정전압과 편향신호에 동기하는 다이나믹 포커스전압이 선택적으로 인가되어 된것에 특징이 있으며, 이는 낮은 다이나믹 포커스전압으로 강력한 4중극렌즈를 형성하여 편향수차에 의한 전자빔의 비점수차를 줄일 수 있는 이점이 있다.The present invention relates to an electron gun for a color cathode ray tube including a preposition tripolar tube portion and three focus electrodes forming a glass potential electrostatic lens. A first electrode having a longitudinal electron beam through hole formed from a negative side, and a first electrode having a blade inserted into the upper and lower ends of the longitudinal electron beam through hole, the second electrode having a constant voltage and a deflection signal; It is characterized by the fact that the dynamic focus voltage in synchronism is selectively applied, which forms a powerful quadrupole lens with a low dynamic focus voltage, thereby reducing the astigmatism of the electron beam due to deflection aberration.
