Driving method for liquid crystal device

Abstract

A driving method for a liquid crystal device comprising a pair of electrodes and a liquid crystal disposed between the electrodes includes a sequence of voltage application operations each comprising application of a reset voltage to the liquid crystal for placing the liquid crystal in a reset state in a reset period and application of a data voltage to the liquid crystal for placing the liquid crystal in a desired gradational display state in a writing period subsequent to the reset period. Each reset voltage is set to provide a prescribed difference in voltage between the each reset voltage and a subsequent data voltage, thus preventing an image memory phenomenon without using an additional reset circuit for exclusively applying the reset voltage to the liquid crystal.
