ABSTRACT:
A method of driving an anti-ferroelectric liquid crystal display (LCD) panel is provided that provides uniform transmittance display characteristics. In the anti-ferroelectric LCD panel, signal electrode lines are arranged in parallel above anti-ferroelectric liquid crystal cells, and at least first and second scan electrode lines are arranged below the anti-ferroelectric liquid crystal cells perpendicular to the signal electrode lines. The method includes a first driving step and a second driving step, which are repeated. Each of the first and second driving steps includes a scanning step, an inversion step, and an iteration step. In the scanning step, a scan selection voltage is applied to the first scan electrode line, and simultaneously, display data signals are applied to the signal electrode lines. In the inversion step, a sustain voltage is applied to the first scan electrode line, and simultaneously, inverted signals of the display data signals which have been applied during the scanning step are applied to the signal electrode lines. In the iteration step, the scanning and inversion steps are repeatedly performed with respect to the second scan electrode line and all of the signal electrode lines.
