Claims (6)
- 저전압을 발생하는 데이터 구동 IC와,외부의 공통전압을 인가받아 차징 펌핑하여 출력하는 차징 펌핑부와,상기 데이터 구동 IC의 각 출력단에 구성되어 상기 차징 펌핑부에서 차징된 전압을 저장하는 복수개의 커패시터와,상기 데이터 구동 IC의 각 출력단에 각각 설치되어 상기 데이터 구동 IC에서 출력된 전압과 상기 커패시터의 출력전압을 외부의 극성제어 신호 및 반전된 극성제어신호에 따라 선택적으로 출력하는 복수개의 스위치부를 포함하여 구성됨을 특징으로 하는 액정표시장치의 구동회로.
- 제 1 항에 있어서, 상기 각 스위치부는 상기 데이터 구동 IC의 각 출력단에 한 쌍의 스위칭 소자가 구성되고, 그 중 하나는 극성제어 신호에 의해 스위칭되어 펌핑된 전압을 출력하고, 다른 하나는 반전된 극성제어 신호에 의해 데이터 구동 IC의 전압을 출력하는 것을 특징으로 하는 액정표시장치의 구동회로.
- 제 1 항에 있어서, 상기 차징 펌핑부는 외부의 공통전압 단자에 직렬로 연결되는 커패시터 및 제 1 다이오드와, 상기 커패시터 및 제 1 다이오드에 병렬로 연결되는 제 2 다이오드로 구성됨을 특징으로 하는 액정표시장치의 구동회로.
- 제 3 항에 있어서, 상기 제 1 다이오드는 공통전압 단자에 역방향으로 연결되고, 상기 제 2 다이오드는 순방향으로 연결되는 것을 특징으로 하는 액정표시장치의 구동회로.
- 제 1 항에 있어서, 상기 스위치부는 극성제어 신호 및 반전된 극성제어 신호가 인가되는 두 라인끼리 서로 엇갈리게 구성하는 것을 특징으로 하는 액정표시장치의 구동회로.
- 제 1 항에 있어서, 상기 차징 펌핑부는 패널 또는 외부의 PCB 기판상에 구성되는 것을 특징으로 하는 액정표시장치의 구동회로.
