Abstract

액정 장치는 전극 매트릭스를 형성하기 위해 주사 전극의 그룹과 주사 전극을 교치하는 데이타 전극의 그룹을 그 위치에 갖는 한쌍의 기판, 및 주사 전극과 온 상태 및 오프 상태를 취하는 데이타 전극의 각 교차점에서 화소를 형성하기 위해 기판 사이에 배열된 액정을 포함하는 액정 디바이스, 주사 신호를 주사 전극에 순차적으로 인가하기 위한 주사신호 인가수단, 제1데이타 신호 및 제2데이타 신호를 주사 신호와 동기하여 상기 데이타 전극에 선택적으로 인가하기 위한 데이타 신호 인가 수단, 및 화소의 온 및 오프 상태를 각각 제공하기 위한 제1 및 제2데이타 신호를 사용하는 첫번째 구동 모드와 화소의 오프 및 온 상태를 각각 제공하기 위한 제1 및 제2데이차 신호를 사용하는 두번째 구동 모드 사이에는 주기적으로 스위칭 하기 위한 제어 수단을 포함한다. 액정 장치는 누화의 발생을 억제하기 위하여 디스플레이 패턴에 따르는 파형 주파수의 변화를 억제하는데 효과적이다.
