Abstract

본 발명은 칼라 음극선관용 전자총을 개시한다.The present invention discloses 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, 4포커스전극과 최종가속전극을 구비하여 된 칼라 음극선관용 전자총에 관한 것으로, 상기 제1, 3포커스전극의 출사측면에 종장형의 전자빔 통과공이 형성되고, 상기 제1포커스 전극과 제3포커스 전극에 포커스 전압을 인가하고, 상기 제2보조전극과 제4포커스전극에는 상기 포커스 전압을 기저전압으로 하며 편향신호에 동기하는 다이나믹 포커스전압을 인가하여 된 것에 그 특징이 있으며, 이는 전 형광막에서 균일한 전자빔단면을 얻을 수 있는 이점을 가진다.The present invention relates to an electron gun for a color cathode ray tube comprising a cathode, a control electrode, and a screen electrode forming an anterior triode, and first, second, third, and four focus electrodes and an final acceleration electrode forming an auxiliary and main lens system. An elongated electron beam through hole is formed on the emission side of the first and third focus electrodes, a focus voltage is applied to the first and third focus electrodes, and the focus voltage is applied to the second auxiliary electrode and the fourth focus electrode. It is characterized by applying a dynamic focus voltage in synchronization with the deflection signal as a base voltage, which has the advantage of obtaining a uniform electron beam cross section in the entire fluorescent film.
