Title: Driving method for liquid crystal display device
Inventor: NAKANO TADATOKI
IPC: G09G3/36
Filed: 1986-05-30
Abstract: PURPOSE:To improve a display contrast by applying a voltage of a waveform in which <=2 pieces of voltage pulses which can maintain a state that a display of a ferroelectric liquid crystal is selected, within a selection time of every one frame period of a transparent electrode. CONSTITUTION:By applying a driving waveform to a liquid crystal cell, a value of a peak voltage of a pulse of a selection time in which its pulse width and bistability appear is measured. The driving waveform can be obtained by an applied waveform of an electrode of a common side which is formed in a liquid crystal cell in the figure A and an applied waveform of an electrode of a segment side shown in the figure B. By a voltage applied to both these electrodes, a voltage applied to the liquid crystal molecule in the liquid crystal cell becomes such a waveform as shown in the figure C, and within the time of t1, the voltage applied to the liquid crystal molecule goes to four times of the applied voltage to the segment, and within the time of t2, said voltage goes to two times in the same way. Therefore, by setting a voltage required for applying the accumulativeness to the liquid crystal molecule, to between a pulse of t1 and a pulse of t2, a state which is selected by t1 can be held during one frame period T.
