Abstract
본 발명은 모니터의 자동입력전환회로에 관한 것으로, 특히 비엔씨(BNC), 디서브(DM-Sub) 두가지 입력 단자를 가진 모니터의 입력절환을 자동으로 전환하도록 한 모니터의 비엔씨(BNC), 디서브(D-Sub)신호 자동 절환회로에 관한 것으로 종래에는 비엔씨와 디서브 2개의 입력단자를 가진 모니터에서 입력신호가 연결되는 방법에 따라 선택스위치(SW1)를 수동으로 절환하여 주어야 하는 문제점이 있었다.
본 발명은 이와 같은 종래 문제점을 해결하기 위하여 고해상도 모니터에 적용하는 비엔씨 및 디서브입력단자를 통해 영상신호 및 수평, 수직동기신호가 입력될 때 마이컴이 주기적으로 수평, 수직동기신호를 판별하여 주기적으로 비엔씨 및 디서브신호를 감지하여 입력신호를 자동으로 절환되게 한 것으로 모니터등에 적용한다.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제2도는 본 발명 모니터의 비엔씨, 디서브신호 자동 절환회로도, 제3도는 본 발명 모니터의 비엔씨, 디서브 신호 자동 절환회로의 스위치 동작을 보인 표, 제4도는 본 발명 모니터의 입력신호에 따른 동작상태를 보인표.
Claims (1)
- 비엔씨(BNC) 및 디서브(D-Sub)신호의 영상신호(R,G,B)를 스위칭하여 영상신호 처리부(10)에 인가하는 영상신호스위칭선택부(SW10)와, 상기 비엔씨 및 디서브신호의 수평, 수직동기신호를 스위칭하여 마이컴(11)에 인가하는 동기신호스위칭선택부(SW11), 상기 디서브신호의 연결유,무를 검출하는 검출부(12)와, 상기 영상신호스위칭선택부(SW10)에서 스위칭선택된 영상신호와 검출부(12)에서 검출된 디서브신호의 연결유,무신호를 입력받아 스위칭출력제어부(13)를 제어하는 마이컴(11)과, 상기 마이컴(11)의 제어신호에 의해 영상 및 동기신호스위칭선택부(SW10)(SW11)를 제어하는 스위칭출력제어부(13)로 구성된 모니터의 비엔씨(BNC), 디서브(D-Sub)신호 자동 절환회로.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
