Abstract:
1. A method of driving an anti-ferroelectric liquid crystal display panel having signal electrode lines arranged in parallel above anti-ferroelectric liquid crystal cells and at least first and second scan electrode lines arranged below the anti-ferroelectric liquid crystal cells perpendicular to the signal electrode lines, the method comprising a first driving step and a second driving step, which are repeated, and wherein each of the first and second driving steps comprises: a scanning step comprising applying a scan selection voltage to the first scan electrode line and simultaneously applying display data signals to the signal electrode lines; an inversion step comprising applying a sustain voltage to the first scan electrode line and simultaneously applying inverted signals of the display data signals which have been applied during the scanning step to the signal electrode lines; and an iteration step comprising repeatedly performing the scanning and inversion steps with respect to the second scan electrode line and to all of the signal electrode lines.
