Abstract

본 발명은 칼라 음극선관용 전자총의 전극을 개시한다.The present invention discloses an electrode of an electron gun for a color cathode ray tube.

본 발명은 전치 삼극부를 이루는 캐소오드, 제어전극 및 스크린전극과 보조 및 주렌즈계를 이루는 제1,2,3,4,5,6,7 포커스전극과 최종가속전극을 구비하여 된 칼라 음극선관용 전자총에 관한 것으로, 상기 스크린 전극과 제1포커스 전극에 정전압이 인가되며, 상기 3,7 포커스 전극에는 정전압 보다 높은 포커스 전압이 인가되고, 상기 제1포커스 전극에는 상기 포커스 전압을 기저전압으로 하면 편향신호에 동기하는 다이나믹 포커스 전압이 인가되며, 상기 제1포커스 전극에는 종장형의 전자빔 통과공이 형성된 것에 특징이 있으며 이는 전형광막에서 균일한 전자빔 단면을 얻을수 있는 이점을 가진다.The present invention relates to a color cathode ray tube electron gun including a cathode, a control electrode, a screen electrode, and a first, second, three, four, five, six, seven focus electrode and a final acceleration electrode forming an auxiliary and main lens system. In claim 1, a constant voltage is applied to the screen electrode and the first focus electrode, a focus voltage higher than a constant voltage is applied to the 3,7 focus electrodes, and the focus signal is a ground voltage to the first focus electrode. A dynamic focus voltage is applied in synchronism to the first focus electrode, and an elongated electron beam through hole is formed in the first focus electrode, which has an advantage of obtaining a uniform electron beam cross section in the typical fluorescent film.
