Abstract

본 발명은 영상표시기기의 온 스크린 표시회로에 관한 것으로서, 특히 온 스크린 출력신호와 수평블랭킹신호를 이용하여 화면상의 특정위치에 영상신호대신 온 스크린 신호를 전송하여 모니터 화면상에 온 스크린의 화면을 표시하고자 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-screen display circuit of an image display device, and more particularly, to transmit an on-screen signal instead of an image signal to a specific position on the screen by using an on-screen output signal and a horizontal blanking signal. It was intended to be displayed.

종래 영상표시기기의 영상신호 표시회로는 퍼스널 컴퓨터로부터 입력되는 R, G, B 영상신호만을 화면에 표시하게 되므로서, 화면의 일정부분에 일정한 밝기로 표시할 수 있는 화면을 제공할 수 없게 된다.Since a video signal display circuit of a conventional video display device displays only R, G, and B video signals input from a personal computer, it is impossible to provide a screen capable of displaying a certain brightness on a certain portion of the screen.

본 발명은 이와같은 종래의 문제점을 해결하기 위하여 화면상의 특정한 위치에 영상신호대신 온 스크린 영상신호를 전송할 수 있도록 온 스크린신호에 의해 발생되는 패스트 블랭킹신호와 수평동기신호를 이용하여 온 스크린신호가 표시되어지고 있을 때는 영상신호를 블랭킹시켜 주도록 하므로서, 화면사의 특정한 위치에 영상신호와는 별개의 항상 일정한 밝기의 온 스크린을 표시할 수 있도록 한 것이다.In order to solve this problem, the present invention displays an on-screen signal using a fast blanking signal and a horizontal synchronization signal generated by the on-screen signal so that the on-screen video signal can be transmitted instead of the video signal at a specific position on the screen. When the video signal is being made blank, the video signal is blanked so that an on-screen screen of a constant brightness, which is separate from the video signal, is always displayed at a specific position of the screen.
