- 비디오 신호 디스플레이 장치의 비디오 신호 전치 증폭부와 스크린 디스플레이부(OSD)에서 각각 인식할 수 있는 비디오 신호 소거 신호를 발생하는 비디오 귀선 신호 공급 회로에 있어서,입력되는 양극성 펄스를 위상 반전시켜 음극성 귀선 소거 신호로 상기 스크린 디스플레이부에 공급하는 제1 위상 반전부와;상기 제1 위상 반전부에서 출력되는 신호를 위상 반전시켜 양극성의 귀선 소거 신호로 상기 비디오 신호 전치 증폭부에 공급하는 제2 위상 반전부로 구성된 것을 특징으로 하는 비디오 귀선 소거 신호 공급 회로.
- 제 1항에 있어서, 상기 제1 위상 반전부는,입력되는 양극성 펄스를 소정 레벨로 증폭시키면서 위상을 반전시켜 음극성의 귀선 소거 신호를 발생하는 트랜지스터를 포함하여 구성된 것을 특징으로 하는 비디오 귀선 소거 신호 공급 회로.
- 제 1항에 있어서, 상기 제2 위상 반전부는,상기 제1 위상 반전부의 출력신호를 소정 레벨로 증폭시키면서 위상 반전시켜 양극성의 귀선 소거 신호를 발생하는 트랜지스터를 포함하여 구성된 것을 특징으로 하는 비디오 귀선 소거 신호 공급 회로.
