| 摘要 | 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. | ||

| 主权项 | 1. A method of driving a bistable nematic dot-matrix liquid crystal display panel capable of selecting black/white only by positive polarity driving or negative polarity driving, the method comprising: applying a first pulse voltage to nematic liquid crystal molecules of the bistable nematic dot-matrix liquid crystal display panel to raise the nematic liquid crystal molecules in the longitudinal direction; after application of the first pulse voltage, applying a second pulse voltage to the nematic liquid crystal molecules for selecting one of two stable orientation states of the nematic liquid crystal molecules; and immediately after application of the second pulse voltage, applying an AC pulse waveform of a voltage lower than a last pulse of the second pulse voltage to thereby remove residual electric charges remaining in the bistable nematic dot-matrix liquid crystal display panel. | ||
