Abstract
본 발명은 모니터의 화면 보정회로에 관한 것으로, 일반적으로 사용되고 있는 기존의 화면 조정회로는 상기와 같은 회로는 가변저항에 의해 수평편향요크로 흐르는 전류를 제어하여 화면의 센터링을 조절하였으므로 화면의 조정이 어렵게 되고 파워의 소비가 매우 크게되며, 센터링 전압의 차가 주파수마다 심하게 되어 주파수에 따른 센터링의 가변 폭이 크게됨으로써 센터링이 잘 조정되지 않는 문제점이 있었다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen correction circuit of a monitor. In the conventional screen adjustment circuit, a circuit such as the above is used to adjust the screen centering by controlling a current flowing in a horizontal deflection yoke by a variable resistor. It becomes difficult and the power consumption is very large, the difference in the centering voltage is severe for each frequency, the variable width of the centering according to the frequency is large, there is a problem that the centering is not adjusted well.
이에 따라, 본 발명의 목적은 상기와 같은 기존의 화면 조정회로에 따르는 결함을 감안하여 수평동기신호의 주파수에 따라 편향요크로 흐르는 전류가 자동으로 제어되도록 하여 화면의 센터링이 정확히 설정되도록 하는 회로를 제공하는데 있다.Accordingly, an object of the present invention is to provide a circuit for accurately setting the centering of the screen by automatically controlling the current flowing in the deflection yoke according to the frequency of the horizontal synchronization signal in consideration of the defects caused by the existing screen adjustment circuit as described above. To provide.
