Driving method for liquid crystal devices |
摘要 |
A liquid crystal device of the type including a pair of substrates having thereon a group of scanning electrodes and a group of data electrodes, and a chiral smectic liquid crystal disposed between the substrates so as to form a pixel at each intersection of the scanning electrodes and the data electrodes, is driven by a driving method causing less crosstalk. The driving method includes the steps of sequentially applying a scanning selection signal to the scanning electrodes, and applying data signals to the data electrodes in synchronism with the scanning selection signal. The scanning selection signal includes a writing pulse having a pulse width DELTA T for determining an optical state of the chiral smectic liquid crystal in cooperation with a data signal. Each data signal includes a data pulse for determining an optical state of the chiral smectic liquid crystal in cooperation with the writing pulse. A plurality of data signals are each designed to have a waveform determined based on a combination of data applied to pixels on at least two consecutively selected scanning electrodes. At least one of said plurality of data signals include an auxiliary pulse having a pulse width shorter than DELTA T.
