Claims (2)
- 수직동기신호(V-Sync)에 의해 리세트되는 어드레스 카운트수단(1)으로부터 출력되는 어드레스정보가 각 영상라인의 컨버어젼스 보정데이타를 저장하고 있는 보정메모리(2)의 어드레스로 출력되어 각 어드레스의 해당 컨버어젼스 보정데이타가 컨버터(3)에서 아나로그신호로 변환되어 컨버어젼스 요크(4)로 출력하도록한 디지탈 컨버어젼스가 채용된 TV에 있어서, 최종 영상라인의 컨버어젼스 보정데이타에 대한 지정 어드레스정보를 검출하기 위한 검출수단(A)과, 외부로부터 동작신호를 입력받아 어드레스 카운트수단(1)의 신호입력단자로 출력하면서 상기 검출수단(A)의 출력신호를 입력받아 어드레스 카운트수단(1)을 제어하기 위한 선택입력수단(B)과, 상기 검출수단(A)의 출력신호를 입력받아 보정메모리(2)를 제어하기 위한 선택출력수단(C)으로 구성됨을 특징으로 하는 디지탈 컨버어젼스가 채용된 TV의 화면찌그러짐 방지 회로.
- 제1항에 있어서, 상기 검출수단(A)은 최종 영상라인에 대한 컨버어젼스 보정데이타의 지정 어드레스 정보를 입력받을 수 있도록 어드레스 카운트수단(1)의 각 카운터(1-1~1-16)의 출력을 논리곱 구성함을 특징으로하는 디지탈 컨버어젼스가 채용된 TV의 화면찌그러짐 방지회로.
