Abstract
(EN)
In the cases of writing display data and erasing written display data, a voltage permitting a potential difference not to include 0V, namely, a voltage of a threshold value which changes optical characteristics of a sealed ferroelectric liquid crystal or higher, is applied between a counter electrode and a pixel electrode. An image is displayed over the entire number of tones, including a low tone side, and display characteristics are improved.
(FR)
Selon la présente invention, dans les cas consistant à écrire des données affichées et à effacer des données écrites affichées, une tension autorisant une différence de potentiel à ne pas inclure 0 V, à savoir, la tension d'une valeur de seuil qui modifie les caractéristiques optiques de cristaux liquides ferroélectriques étanches ou plus, est appliquée entre une contre-électrode et une électrode de pixel. Une image est affichée sur le nombre complet de tons, y compris un ton de côté bas et les caractéristiques de l'affichage sont améliorées
