Abstract

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

본 고안은 전치삼극관부를 이루는 캐소오드 제어전극 및 스크린 전극과, 주렌즈계로서 제1,2 유니 포텐셜형 포커스 정전렌즈를 이루는 복수개의 포커스전극과, 상기 포커스전극중 적어도 하나의 포커스전극 인접되게 설치되어 바이포텐셜형 포커스 정전렌즈를 이루는 최종가속전극를 구비하여 된 칼라 음극선관용 전자총에 관한 것으로, 제1,2 유니 포텐셜형 포커스 정전렌즈를 이루는 포커스전극중 상기 캐소우드 측에 위치되어 고전위가 인가되는 포커스 전극의 전자빔 통과공이 상기 최종가속 전극측에 위치되어 상기 고전위보다 상대적으로 낮은 저전위가 인가되는 포커스전극의 전자빔통과공 보다 크게 형성된 것에 특징이 있으며, 이는 보조 정전렌즈와 주 정전렌즈의 구면수차를 대폭 줄일 수 있는 이점를 가진다.The present invention is provided so that the cathode control electrode and the screen electrode constituting the pre-triode tube portion, a plurality of focus electrodes constituting the first and second universal potential electrostatic lens as the main lens system, and at least one focus electrode of the focus electrodes The present invention relates to an electron gun for a color cathode ray tube having a final accelerating electrode forming a bipotential focus electrostatic lens, wherein a focus positioned on the cathode side of a focus electrode forming a first and second unpotential focus electrostatic lens is applied to a high potential The electron beam passing hole of the electrode is located on the side of the final acceleration electrode and is formed to be larger than the electron beam passing hole of the focus electrode to which a low potential relatively lower than the high potential is applied, which is spherical aberration of the auxiliary electrostatic lens and the main electrostatic lens. It has the advantage that can be greatly reduced.
