Abstract
본 발명은 모니터에 관한 것으로서, 특히 음극선관에 인가되는 그레이드(Grid) 전류를 수직 편향 신호 및 수평 편향 신호의 크기에 의해 제어함으로써, 비디오 신호가 음극선관의 새도우 마스크에 정확하게 주사되는 디스플레이 안정화 회로에 관한 것이다. 이와같은 본 발명은 입력되는 편향 신호(Df)의 크기를 검파하는 편향 신호 검파부(10)와, 편향 신호 검파부(10)에 의해 검파된 편향치와 미리 설정된 기준치(Vref)와 비교하여 그 차가 출력되는 비교부(20)와, 상기 비교부(20)에서 출력되는 비교치로 따라 그레이드 단자(G1)를 통해 음극선관(CRT)에 인가되는 전류를 제어하는 제어부(30)로 구성된다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitor, and more particularly, to a display stabilization circuit in which a video signal is accurately scanned into a shadow mask of a cathode ray tube by controlling the grid current applied to the cathode ray tube by the magnitude of the vertical deflection signal and the horizontal deflection signal. It is about. The present invention compares the deflection signal detector 10 for detecting the magnitude of the input deflection signal Df, the deflection value detected by the deflection signal detector 10 with the preset reference value Vref. Comparing unit 20 that the difference is output, and a control unit 30 for controlling the current applied to the cathode ray tube (CRT) through the grade terminal (G1) according to the comparison value output from the comparing unit 20.
