Abstract

본 발명은 모니터의 회로에 관한 것으로, 특히 모니터의 수평모드 변환시 릴레이를 이용함으로써 모니터 내부의 온도를 낮추어 스위칭시 열이 발생하는 것을 방지할 수 있고, 회로를 간략화할 수 있도록, 수형 출력 트랜지스터와 댐퍼 다이오드의 상호 작용에 의하여 편향 코일(DY)에 톱니파 전류를 흘려 전자빔을 수평 방향으로 주사시키기 위한 수평 출력부와, 상기 수평 출력부에서 수평 방향으로 주사된 전자빔의 수평 귀선 및 직선성을 보상해 주는 모드 보상부 및, 각 수평 주파수에 따른 모드를 선택하기 위한 모드 선택부로 구성된 수평 모드 보상 회로에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit of a monitor, and in particular, by using a relay during the horizontal mode conversion of the monitor, it is possible to lower the temperature inside the monitor to prevent heat generation during switching, and to simplify the circuit. The horizontal output unit for scanning the electron beam in the horizontal direction by flowing a sawtooth current through the deflection coil (DY) by the interaction of the diode, and compensates the horizontal retrace and linearity of the electron beam scanned in the horizontal direction from the horizontal output unit A horizontal mode compensation circuit comprising a mode compensator and a mode selector for selecting a mode according to each horizontal frequency.
