Abstract

본 발명은 디스플레이 패널의 잔상을 최소한으로 하면서 소비 전류도 최소한으로 하는 디스플레이 구동회로 및 구동방법을 개시한다. 상기 디스플레이 구동회로는, 유효데이터 및 흑색데이터에 대응되는 구동신호를 생성하여 디스플레이 패널에 전달하며, N(N은 정수)개의 데이터선택스위치, N개의 버퍼, N개의 버퍼출력선택스위치 및 복수 개의 전하분배스위치를 구비한다. 상기 N개의 데이터선택스위치는 상기 유효데이터 및 상기 흑색데이터 중 하나를 선택한다. 상기 N개의 버퍼는 상기 데이터선택스위치에서 선택된 신호를 각각 버퍼링 한다. 상기 N개의 버퍼출력선택스위치는 상기 버퍼의 출력을 스위칭하여 상기 구동신호를 각각 출력한다. 상기 복수 개의 전하분배스위치는 이웃하는 2개의 구동신호를 서로 연결시킨다.
