  • Patent number: 6720947
    Abstract: A method for driving an anti-ferroelectric liquid crystal display (LCD) panel in which a plurality of parallel signal electrode lines are arranged over anti-ferroelectric liquid crystal cells (LCs) and a plurality of parallel scan electrode lines are arranged below the anti-ferroelectric LCs, perpendicular to the signal electrode lines is provided. The method includes the steps of selectively shifting LCs into a ferroelectric state, keeping the selected LCs in the ferroelectric state, activating the selected LCs, and restoring the activated LCs to an anti-ferroelectric state. In particular, a scan selection voltage is applied to a scan electrode lines to be scanned, and a display data signal is applied to all of the signal electrode lines, to selectively shift LCs into a ferroelectric state.
