Abstract

본 발명은 칼라 음극선관용 전자총을 개시한다. 본 발명은 인라인상으로 배열된 세 개의 캐소오드와, 각각 세개의 전자빔 통과공이 형성된 제어전극 및 스크린 전극을 구비하여 된 칼라 음극선관용 전자총에 관한 것으로, 상기 제어전극에 형성된 전자빔 통공이 수직폭이 수평폭보다 좁은 횡장형인 것에 특징이 있으며, 이는 형광면에 랜링되는 전자빔 단면을 크기를 전 형광막에서 균일하게 할수 있는 이점을 가진다.The present invention discloses an electron gun for a color cathode ray tube. The present invention relates to an electron gun for a color cathode ray tube comprising three cathodes arranged inline, and a control electrode and a screen electrode each having three electron beam through holes, wherein the electron beam through holes formed in the control electrode have a vertical width. It is characterized by being narrower than the width, which has the advantage of uniformizing the size of the electron beam cross section, which is lanted on the fluorescent surface, in the entire fluorescent film.
