    摘要: A method of driving a liquid crystal that has a memory capability, wherein a reset voltage is initially applied to the liquid crystal during a reset period, to bring about a Freédericksz transition in the liquid crystal. During a subsequent selection period, a selection voltage that is selected on the basis of a critical value that brings about one of two metastable states in the liquid crystal is applied to the liquid crystal, and, during a non-selection period that follows the selection period, a non-selection voltage that is less than or equal to a threshold value that maintains two metastable states is applied to the liquid crystal. A delay period is provided between the reset period and the selection period, in order to gain effective timing for applying the selection voltage to the liquid crystal after the application of the reset voltage has been turned off. This shortens the length of the selection period, and hence the write time.

    摘要: A time-sharing addressing method for an antiferroelectric phase liquid crystal element that demonstrates tristable switching behavior, wherein the drive voltage waveform is made an alternating current and the time average value of the voltage, including the depolarization field due to spontaneous polarization of the liquid crystal, actually applied to the liquid crystal substance in one frame or two frames is made zero for the purpose of expanding the drive voltage margin and the operating temperature margin of the element, shortening the screen scanning time and preventing degradation of the electro-optical characteristic by suppressing polarization of the electric charge due to spontaneous polarization of the liquid crystal. Also, by providing the blanking period required for relaxation from a ferroelectric phase to an antiferroelectric phase in the non-selection period, the time required for screen scanning is shortened, and by changing the length of the blanking period according to the temperature dependence of the response-relaxation time, the operating temperature margin is expanded.
