Abstract

본 발명은 소비되는 전류를 최소한으로 하는 디스플레이 구동회로를 개시(introduce)한다. 상기 디스플레이 구동회로는, 버퍼부, N도트 스위치회로, 전하분배 스위치회로 및 공유전압준위조정 스위치회로를 구비한다. 상기 버퍼부는 복수 개의 디지털-아날로그 변환기로부터 출력되는 복수 개의 화소구동신호들을 버퍼링한다. 상기 N도트 스위치회로는 도트 인버젼 방식에 따라 결정되는 제1경로선택신호 및 제2경로선택신호에 응답하여 상기 버퍼부로부터 출력되는 복수 개의 화소구동신호들의 경로를 선택하여 복수 개의 출력단자들로 스위칭한다. 상기 전하분배 스위치회로는 전하분배제어신호에 응답하여, 상기 복수 개의 출력단자들 사이의 전하를 분배한다. 상기 공유전압준위조정 스위치회로는 공유전압준위제어신호에 응답하여 상기 복수 개의 출력단자들 사이의 전하분배 및 전하분배시의 전압준위를 제어한다.
