Abstract

본 발명은 칼라 수상관용 전자총에 관한 것으로 특히 구면수차에 의한 전자빔 스포트 특성의 열화를 방지하고, 비점수차를 제거하여 칼라 수상관의 해상도를 향상시킬 수 있도록 한 것으로서, 구면수차의 영향을 줄이기 위한 큰 개구부를 이루고 내부에는 비점수차의 영향을 줄이기 위하여 정전제어 전극을 구성한 애노드전극 및 포커스전극과, 상기 정전제어 전극에는 1개의 중앙개공부와 양측면에 개구부를 형성하고 일부가 1개 이상으로 절곡된 것에 있어서, 상기 중앙개공부는 수평경보다 수직경이 더 큰 직사각형의 개공부와, 상기 개구부는 직육각형의 반형태로 구성한 것이다.The present invention relates to an electron gun for a color receiving tube, and in particular, to prevent deterioration of electron beam spot characteristics due to spherical aberration, and to improve the resolution of the color receiving tube by removing astigmatism. An anode and a focus electrode constituting an electrostatic control electrode to form an opening and reducing an influence of astigmatism therein, and the electrostatic control electrode is formed with one central opening and openings at both sides thereof, and part of which is bent at least one. In this case, the central opening is a rectangular opening having a larger vertical diameter than the horizontal diameter, and the opening is formed in a rectangular shape of half.
