Abstract

이 발명은 편향요크의 미스컨버젼스 보정장치를 게재한다. 이 발명은 수직편향코일에 직렬로 연결된 제1수직보정코일과, 이와 병렬로 연결된 제2수직보정코일과, 이 제2수직보정코일에 직렬로 연결된 한쌍의 다이오드와, 이 다이오드를 턴온 조정하는 저항으로 구성된 보조회로를 부착시킨 편향요크의 미스컨버젼스 보정장치에 관한 것이다.This invention discloses the misconvergence correction apparatus of a deflection yoke. The present invention relates to a first vertical correction coil connected in series to a vertical deflection coil, a second vertical correction coil connected in parallel thereto, a pair of diodes connected in series to the second vertical correction coil, and a resistor for turning on the diode. It relates to a misconvergence correction device of a deflection yoke having an auxiliary circuit composed of

따라서 고해상도의 모니터에서 발생하는 화면의 수직축으로의 비선형적인 사이드 빔인 R빔과 B빔의 미스컨버젼스를 화면의 각 포인트에서 능동적으로 컨버징(converging)시킬 수 있으며, 또한 음극선관(CRT) 제작자의 설계에 따라 달라지는 미스컨버젼스 패턴을 편향요크의 수평편향코일이나 수직편향코일의 재설계없이도 평면화 및 대형화 추세에 의해 발생하는 비선형적인 미스커버젼스 특성을 개선시킬 수 있다.Therefore, the misconvergence of the R and B beams, which are nonlinear side beams on the vertical axis of the screen generated in a high resolution monitor, can be actively converged at each point of the screen, and also designed by the cathode ray tube (CRT) maker. The non-convergence pattern caused by the flattening and enlargement trends can be improved without redesigning the deflection yoke's horizontal deflection coil or vertical deflection coil.
