(JA) 双安定ネマチックのドットマトリクス液晶表示パネルの駆動方法及び駆動デバイス
Abstract: front page image
 画面点滅時の消費電圧を抑制する。画像が書き込まれ保持した状態で、低い電圧で低周波数の波形を双安定液晶表示パネル全面に加えると液晶分子は基板に対して垂直な状態までは行かないまでもある程度傾き画面が白に近いグレー表示になる。その後、電圧印加をやめると双安定液晶表示パネルは配向状態が壊れていないので、印加前に表示していた画像が現れる。このことを利用して、ある一定時間間隔で低電圧、低周波数の波形を印加するのと、無印加状態を繰り返すため、低消費電力で画面を点滅できる。
