Abstract
본 발명은 TV의 모드 제어장치에 관한 것으로, 특히 PC모니터 디스플레이 기능을 TV에 추가하고 PC 모드와 TV 모드를 제어하도록한 PC 모드 기능을 갖는 TV의 모드 제어장치에 관한 것이다.The present invention relates to a mode control apparatus for a TV, and more particularly, to a mode control apparatus for a TV having a PC mode function for adding a PC monitor display function to the TV and controlling the PC mode and the TV mode.
이와 같은 본 발명의 PC 모드 기능을 갖는 TV의 모드 제어장치는 TV 또는 PC 비디오 신호중 일 신호를 선택적으로 입력하는 입력수단과, 상기 입력수단에 의해 입력된 신호의 동기신호를 일정 극성으로 보정하여 TV의 편향 드라이브 제어부에 인가하는 동기신호 극성 보정수단과, 상기 동기신호 극성 보정수단에서 출력된 동기신호를 카운트하여 주파수를 판별하는 카운터와, 상기 입력수단에 의해 입력된 신호의 동기 모드를 판단하여 출력하는 동기 모드 판별수단과, 상기 카운터 및 동기 모드 판별수단에서 출력된 신호로 부터 TV 또는 PC 모드를 구분하여 해당 모드로 제어하는 마이콤을 포함하여 구성된 것이다.The mode control apparatus of a TV having a PC mode function of the present invention includes an input means for selectively inputting one signal of a TV or PC video signal, and correcting a synchronization signal of a signal input by the input means with a predetermined polarity. A synchronizing signal polarity correcting means applied to the deflection drive control section of the control unit, a counter for counting the frequency by synchronizing the synchronizing signal outputted from the synchronizing signal polarity correcting means, and determining and outputting the synchronizing mode of the signal inputted by the input means. And a micom for distinguishing a TV or PC mode from the signals output from the counter and the synchronous mode determining means and controlling the corresponding mode.
