Abstract

본 발명은 모니터의 다이나믹포커스를 위한 수평신호발생회로에 관한 것으로, 수평편향신호를 사용하여 수평파라볼라신호를 생성하는 파라볼라신호생성부와, 이 파라볼라신호생성부의 일단에 연결되어 파라볼라신호의 출력이득을 제어하는 이득제어부와, 이 이득제어부의 이득제어동작을 스위칭제어하는 마이컴과, 상기 이득 제어부의 일단에 연결되어 수평파라볼라신호를 증폭하는 출력증폭부로 이루어져, 설정모드에 따라 바이어스 저항값을 적절히 설정해 주도록 함으로써, 설정모드신호에 관계없이 수평파라볼라신호의 출력이득을 적절히 조절하게 유지시킬 수 있으므로 이에따라 파라볼라 파형의 균형성을 향상시켜주게 됨은 물론 정확한 파라볼라 파형에 의해 다이나믹 포커싱 동작이 이루어지므로 이에따라 시스템의 가능성도 향상되도록 된다.The present invention relates to a horizontal signal generating circuit for dynamic focusing of a monitor, comprising: a parabola signal generating unit for generating a horizontal parabola signal using a horizontal deflection signal; and connected to one end of the parabola signal generating unit to obtain an output gain of the parabola signal. A gain control section for controlling, a microcomputer for switching control of the gain control operation of the gain control section, and an output amplifier section connected to one end of the gain control section for amplifying a horizontal parabolic signal, so as to appropriately set the bias resistance value according to the setting mode. Thus, the output gain of the horizontal parabola signal can be properly adjusted regardless of the setting mode signal, thereby improving the balance of the parabola waveforms, as well as the dynamic focusing operation by the accurate parabola waveforms. To improve do.
