Abstract

본 발명은 온스크린 디스플레이가 가능한 모니터에 관한 것으로서, 특히 온스크린 디스플레이를 이용하여 콘텍터가 연결되지 않음을 사용자에게 알려줌으로써, 비디오 신호의 테스팅을 용이하게 행할 수 있는 모니터의 비디오 신호 테스팅 회로 및 방법에 관한 것이다. 이와 같은 본 발명은 콘넥터를 통해 입력되는 동기 신호가 없으면 콘넥터가 연결되지 않은 것으로 판단되어 온스크린 신호가 디스플레이되는 화면의 사이즈와 온스크린 신호의 크기가 최대로 설정되고 최대 사이즈 및 최대 크기로 설정된 온스크린 신호에 의해 화면 전체가 화이트로 디스프레이되어 콘넥터의 연결 여부가 사용자에게 알려지도록 구성된다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitor capable of an on-screen display. In particular, a video signal testing circuit and method of a monitor that can easily test a video signal by informing a user that a contactor is not connected by using an on-screen display. It is about. In the present invention as described above, if there is no synchronization signal input through the connector, it is determined that the connector is not connected, and the size of the screen and the size of the on-screen signal on which the on-screen signal is displayed are set to the maximum and the maximum size and the maximum size. The entire screen is displayed in white by the screen signal so that the user is informed whether the connector is connected or not.

모니터의 비디오신호 테스팅회로 및 방법Video signal testing circuit and method of monitor

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명에 따른 모니터의 비디오신호 테스팅회로의 구성을 보인 도면2 is a diagram showing the configuration of a video signal testing circuit of a monitor according to the present invention.

Claims (2)

콘넥터를 통해 입력되는 동기 신호의 유,무를 판단하여 제어 신호가 출력되는 마이크로 프로세서와, 상기 마이크로 프로세서에서 출력되는 제어 신호에 의해 온스크린 신호가 디스플레이되는 화면의 크기가 최대이고 온스크린 신호의 크기가 최대로 출력되는 온스크린 디스플레이 수단과, 상기 온스크린 디스플레잉 수단을 통해 출력되는 온스크린 신호가 중폭되어 화면 전체가 화이트로 디스플레이되는 메인 중폭 수단으로 구성된 모니터의 오디오 신호 테스팅 회로.The microprocessor outputs a control signal by determining the presence or absence of a synchronization signal input through the connector, and the screen on which the on-screen signal is displayed by the control signal output from the microprocessor is the largest and the size of the on-screen signal is And an on-screen display means for maximum output, and an on-screen signal output through the on-screen display means to be heavy so that the entire screen is displayed in white. 콘넥터를 통해 입력되는 동기 신호가 없으면 콘넥터가 연결되지 않은 것으로 판단되어 온스크린 신호가 디스플레이되는 화면의 사이즈와 온스크린 신호의 크기가 최대로 설정되고 최대 사이즈 및 최대 크기로 설정된 온스크린 신호에 의해 화면 전체가 화이트로 디스플레이되어 콘넥터의 연결 여부가 사용자에게 알려지도록 구성된 모니터의 비디오 신호 테스팅 방법.If there is no sync signal input through the connector, it is judged that the connector is not connected, and the screen size and the size of the on-screen signal on which the on-screen signal is displayed are set to the maximum, and the screen is set by the on-screen signal set to the maximum size and the maximum size. A method of testing video signals on a monitor configured to display in full white so that the user is informed of whether or not a connector is connected. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
