Abstract

이 발명은 미스컨버젼스 보정장치에 관한 것으로서, 화면의 상하측에는 전자빔이 정상적으로 주사되고, 화면의 중앙부에는 적색빔과 청색빔이 서로 교차되어 발생하는 미스컨버젼스를 보정하기 위하여 수직 편향 자계를 발생하는 수직편향코일에 병렬로 다이오드를 구성하여 다이오드의 스위칭 포인트 이상의 전압이 인가되면 수직편향코일에 전류가 인가되지 않도록 함으로써, 상기 미스컨버젼스를 보정하였다.The present invention relates to a device for correcting misconvergence, wherein a vertical deflection for generating a vertical deflection magnetic field in order to correct misconvergence generated by the electron beam is normally scanned on the upper and lower sides of the screen and the red and blue beams intersect at the center of the screen. The misconvergence was corrected by constructing a diode in parallel with the coil so that no current was applied to the vertical deflection coil when a voltage above the switching point of the diode was applied.

이 발명은 모든 편향요크에 사용할 수 있다.This invention can be used for all deflection yokes.
