<p>The present invention relates to a driving method and system for a display device adopting an antiferroelectric liquid crystal, and realizes a fast and excellent driving method for an antiferroelectric liquid-crystal display device in which, since the antiferroelectric liquid crystal is reset to a ferroelectric state at every writing, and the states of the antiferroelectric liquid crystal to be attained during a selection period and non-selection period respectively are defined, an after-image phenomenon can be alleviated. A scanning period is composed of a reset period, selection period, and non-selection period. During the reset period, the antiferroelectric liquid crystal is brought to a ferroelectric state. During the selection period, a pulse of 0 V or of opposite polarity is applied. During the non-selection period, the antiferroelectric liquid crystal is controlled to enter an antiferroelectric state or a ferroelectric state to be set with application of a voltage of the same polarity as a voltage to be applied during the reset period. <IMAGE></p> |
