Abstract
본 발명은 칼라 수상관용 전자총에 관한 것으로 특히 주렌즈부를 확장하여 구면수차에 의한 전자빔 스포트 특성의 열화를 방지하고 비전수차를 제거하여 칼라 수상관의 해상도를 향상시키도록한 것으로서 전자총에서 방출된 전자빔이 통과할 때 구면수차의 영향을 줄이기 위하여 포커스전극과 애노드전극의 주연에 근접된 크기로 형성한 개구부와 상기 개구부를 크게 함으로써 발생되는 비점수차의 영향을 줄이기 위하여 포커스전극과 애노드전극의 소정 깊이내에 개구부와 개공부를 갖는 내측전극판을 구성한 것이다.The present invention relates to an electron gun for a color receiving tube. In particular, the main lens unit is extended to prevent deterioration of electron beam spot characteristics due to spherical aberration, and to remove the vision aberration to improve the resolution of the color receiving tube. Openings within a predetermined depth of the focusing electrode and the anode electrode in order to reduce the influence of astigmatism caused by increasing the opening and the opening formed to a size close to the peripheral of the focus electrode and the anode electrode in order to reduce the influence of spherical aberration when passing through And an inner electrode plate having openings.
