Abstract
A driving method for a liquid crystal device includes the steps of providing a first substrate with a unidirectionally aligned data electrode group and a second substrate with a select-electrode group aligned perpendicularly to the data electrode; applying a select pulse to the select electrodes; and providing a pause corresponding to at least one line before a data-pulse sequence is applied to the data-electrode group. The select pulse can be synchronized with the data-pulse sequence by shifting them a half line relative to each other so that the select pulse and the data pulse have opposite polarity in relation to each other. Alternatively, the select pulse is applied while the data pulse sequence is applied to the data electrode group. In the latter case, the time and/or voltage is determined so as to offset the effects of the reversed electric field generated during switching of the liquid crystal.
