Abstract

본 발명은 전계 확장에 의한 대구경 메인 렌즈를 가지는 칼라 음극선관용 전자총에 관하여 기술한다.The present invention describes an electron gun for color cathode ray tubes having a large diameter main lens by electric field extension.

본 발명의 전자총의 포커스 전극의 최종 전극 요소에 수직 방향의 전계를 약화시키는 윈도우 또는 함몰부가 독립빔 통과공과 림의 사이에 마련된다.A window or depression is provided between the independent beam passing hole and the rim to weaken the electric field in the direction perpendicular to the final electrode element of the focus electrode of the electron gun of the present invention.

이로써, 수직 수평 방향 전계간의 강도차가 감소되게 되어 보다 정상원에 가까운 빔스포트를 형성할 수 있고, 나아가서는 양질의 화상을 실현할 수 있다.As a result, the intensity difference between the vertical and horizontal electric fields is reduced, so that a beam spot closer to the normal circle can be formed, and further, a good image can be realized.
