Abstract

본 발명은 리니어리티 제어 회로에 관한 것으로, 일반적으로 수평출력 방식은 리니어리티 코일의 리액턴스 값 및 자석의 방향이 결정되므로 리니어리티를 가변할 수 없고, 세트에서 리액턴스 값 오차 및 주변의 여러 부품들의 오차로 인해 리니어리티가 맞지 않는 문제점이 있으므로, 본 발명은 이러한 문제점을 해결하기 위해서 중앙처리장치에서 입력 동작 기간을 조정함으로써 스위칭 트랜지스터의 온 시간이 길어지게 되면 그 만큼 전류가 많이 흐르게 되므로 유기되는 자속도 커지게 되어 그 크기에 따라 회면의 좌/우 크기를 조정할 수 있다.Since the reactance value of the linearity coil and the direction of the magnet are determined, the linearity can not be varied. In addition, since the reactance value error in the set and the error of various components in the vicinity cause the linearity In order to solve such a problem, the present invention adjusts the input operation period in the central processing unit to increase the ON time of the switching transistor, Depending on the size, you can adjust the left / right size of the face.
