Abstract

본 발명은 칼라 음극선관용 전자총을 개시한다.The present invention discloses an electron gun for a color cathode ray tube.

본 발명은 삼극부를 이루는 캐소오드, 세 전자빔 통과공이 형성된 제어전극 및 스크린전극과, 보조렌즈 및 주렌즈를 이루는 복수개의 포커스전극과, 이 포커스전극과 인접되게 설치되며 제1콘버어젼스 수단이 마련된 최종가속전극을 구비하여 된 칼라 음극선관용 전자총에 관한 것으로, 보조렌즈를 이루는 적어도 하나의 포커스 전극에 제2콘버어젼스 수단이 마련된 것에 특징이 있으며, 이에따라 전자총의 콘버어젼스 특성을 향상시킬 수 있다.The present invention provides a cathode comprising a three-pole portion, a control electrode and a screen electrode having three electron beam through holes, a plurality of focus electrodes forming an auxiliary lens and a main lens, and adjacent to the focus electrode and provided with a first convergence means. The present invention relates to an electron gun for a color cathode ray tube provided with a final acceleration electrode, characterized in that a second convergence means is provided on at least one focus electrode constituting the auxiliary lens, thereby improving the convergence characteristic of the electron gun. .
