Abstract

칼라 음극선관용 전자총을 개시한다. 이 전자총은 필드에미터로 이루어진 음극구조체와, 이 음극구조체로부터 방출된 전자빔을 집속하기 위해 메인펜즈를 형성하는 포커스 전극과, 최종가속전극을 구비하여 된 것에 그 특징이 있으며, 이는 삼극부의 의한 전자빔의 직경확대 및 메인렌즈에서의 구면수차를 줄일 수 있는 이점을 가진다.Disclosed is an electron gun for a color cathode ray tube. This electron gun is characterized by having a cathode structure made up of a field meter, a focus electrode forming a main fence for focusing an electron beam emitted from the cathode structure, and a final acceleration electrode, And the spherical aberration in the main lens can be reduced.
