Abstract:
In method of driving a bistable nematic dot-matrix liquid crystal display panel, a first pulse voltage is applied to nematic liquid crystal molecules to raise the nematic liquid crystal molecules in the longitudinal direction. After application of the first pulse voltage, a second pulse voltage is applied to the nematic liquid crystal molecules for selecting one of two stable orientation states of the nematic liquid crystal molecules. Immediately after the application of the second pulse voltage, an AC pulse waveform of a voltage lower than a last pulse of the second pulse voltage is applied to thereby remove residual electric charges remaining in the bistable nematic dot-matrix liquid crystal display panel.
