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, 주렌즈계를 이루는 제1,2,3,4,5, 포커스 전극과 제5포커스 전극과 인접되게 설치된 최종 가속전극을 구비하여 된 칼라 음극선관용 전자총에 관한 것으로, 상기 제1,3,5포커스 전극과, 상기 제2,4포커스 전극에 편향신호에 동기하며 서로 다른 제1,2다이나믹 포커스 전압이 인가된 것에 특징이 있으며, 이는 전형광면에 랜딩되는 전자빔의 단면을 균일하게 할 수 있는 이점을 가진다.The present invention includes a cathode, a control electrode and a screen electrode forming the pre-triode, and a final acceleration electrode disposed adjacent to the first, second, third, fourth, fifth, focus and fifth focus electrodes forming the main lens system. The present invention relates to an electron gun for a color cathode ray tube, characterized in that the first, third and fifth focus electrodes and the second and fourth focus electrodes are applied with different first and second dynamic focus voltages in synchronization with a deflection signal. There is an advantage that the cross section of the electron beam landing on the conventional light emitting surface can be made uniform.
