Abstract

본 발명은 전자빔 편향시 발생하는 비점수차를 보상하여 원형의 비임 스폿을 얻을 수 있는 칼라 음극선관용 전자총을 제공하는 데 목적이 있다.An object of the present invention is to provide an electron gun for a color cathode ray tube that can obtain a circular beam spot by compensating astigmatism generated during electron beam deflection.

이를 실현하기 위하여 본 발명은 집속전극을 분할하여 이들 전극사이에 편향신호에 동기하여 비례적으로 증감하는 전압이 인가되는 1쌍의 가변전위 전극과, 이들 전극사이에 집속 전극에 인가되는 전압과 동일한 전압이 인가되는 고정전위 전극이 배치되어 편향전에 횡장형의 편향수치를 미리 모정할 수 있는 칼라 음극선관용 전자총을 제공하고 있다.In order to realize this, the present invention divides the focusing electrodes and applies a pair of variable potential electrodes to which a voltage that is proportionally increased or decreased in synchronization with the deflection signal is applied between these electrodes, and a voltage equal to the voltage applied to the focusing electrodes between these electrodes. The fixed potential electrode to which a voltage is applied is arrange | positioned, and the electron gun for color cathode ray tubes which can estimate a horizontal deflection value before deflection is provided.
