Claims (3)

  1. 디지탈 비디오신호가 입력되고 복수의 병렬신호전극으로 구성된 표시장치의 구동회로에 있어서 신호전압이 서로 상이한 레벨을 가진 복수의 신호전압을 공급하는 전압공급수단과 ; 상기 전압공급수단에 연결되어 상기 디지탈 비디오신호를 받아들이고, 상기 디지탈 비디오신호와 일치하여 상기 신호전압의 하나를 선택하며, 또한 상기 선택된 신호전압을 공급하는 전압선택수단과 ; 상기 신호전극의 각각에 신호전압에 제공되고 신호입력스위칭소자로 제공된 상기 각 신호선인 상기 전압선택수단으로부터 신호전압을 받아들이는 복수의 신호선을 가지며, 신호 홀딩커패시터와 신호출력 스위칭소자를 가지는 신호전압수단과 ; 상기 전압선택 수단으로부터 상기 전압이 순차적으로 받아들이는 위상과 상기 전압이 전혀 받아들여지지 않는다른 위상이 교호적으로 반복되는 것에 의해서 선택신호를 발생하는 선택신호 발생수단, 상기 선택신호 발생수단은 상기 신호전압수단의 각각의 복수의 신호선의 신호입력 스위칭소자와 각각 연결되며 ; 또한 상기 전압이 상기 신호전극에 출력되는 위상과 상기 전압이 출력되지 않은 다른 위상이 서로 교호적으로 반복되는 것에 의해서 제어신호를 발생하는 제어신호 발생수단, 상기 제어신호는 상기 선택신호로부터 반전되며, 상기 제어신호 발생수단은 상기 신호전압수단의 각각의 복수의 신호선의 신호출력 스위칭소자에 각각 연결되는 표시장치의 구동회로.
  2. 제 1 항에 있어서, 상기 구동회로는 상기 전압선택수단의 소정수를 포함하며 각 전압선택수단은 상기의 소정수마다 신호전극에 대응하여 신호전압수단에 연결되며, 또한 상기의 선택신호 발생수단은 상기 디지탈 비디오신호의 기간만큼 긴 시간의 소정수로 계속되는 기간동안에 상기 신호입력 스위칭소자가 크로스되므로서 선택신호를 발생하는 표시장치의 구동회로.
  3. 제 1 항에 있어서, 상기 신호 홀딩커패시터는 상기 신호입력 스위칭소자와 상기 신호출력 스위칭소자 사이에 연결되는 표시장치의 구동회로.
