Abstract

본 발명은 모니터에서 엑스-레이가 방출되는 것을 차단함과 동시에 화면에 경고 문자를 디스플레이해 줄 수 있게 한 모니터의 엑스-레이 차단 회로에 관한 것으로 R.G.B 신호를 일정폭으로 증폭시키는 프리 앰프와, 상기 프리 앰프의 출력으로 씨알티에 영상으로 나타나도록 처리하는 영상 처리부와, 상기 씨알티에 고압을 인가하기 위한 플라이 백 트랜스를 포함하여 구성되는 모니터 회로에 있어서, 상기 플라이 백 트랜스로 부터 과전류나 과전압이 발생할때 스위칭되는 스위칭 회로와, 상기 스위칭 회로로 부터 저전위가 입력될때 이를 인식하여 파우어 공급부를 DPMS 오프 모드로 전환시킴과 동시에 오에스디 동작부를 제어하는 마이컴과, 상기 마이컴의 제어에 따라 상기 영상 처리부로 엑스-레이 차단에 따른 경고 문자를 발생시키는 오에스디 동작부를 포함하여 이루어진다.The present invention relates to an X-ray blocking circuit of a monitor which prevents the emission of X-rays from the monitor and displays warning characters on the screen. The present invention relates to a preamplifier for amplifying an RGB signal at a predetermined width. A monitor circuit comprising a video processing unit for processing the output of a preamplifier to appear as a SeaTier image and a flyback transformer for applying high pressure to the SeaTier, when an overcurrent or overvoltage occurs from the flyback transformer. A switching circuit, a microcomputer that recognizes when a low potential is input from the switching circuit, switches the power supply unit to a DPMS off mode, and simultaneously controls an OSD operation unit; OSD operation unit to generate warning text due to blocking the ray It is made, including.
