  • Patent number: 6236385
    Abstract: 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.

  • Patent number: 5035489
    Abstract: An electro-optical device includes at least two adjacent transparent twisted nematic liquid crystal cells, each cell having a twisted nematic liquid crystal with a twist angle greater than 90.degree. between a pair of spaced apart opposed substrates with electrodes selectively disposed thereon. A linear polarizer is disposed on an exterior surface of each of the two cells. One of the two cells includes a plurality of electrodes for selectively producing a desired display. Application of a suitable voltage to the second cell compensates for changes in ambient temperature conditions or undesirable thicknesses in the liquid crystal materials of the two cells to ensure that a monochromatic display having excellent contrast is produced by the device and compensates for elliptically polarized light emitted by the first cell so that the device produces substantially linearly polarized light.

  • Patent number: 4850676
    Abstract: A method and circuits for multiplex driving of a liquid crystal element employing a ferroelectric liquid crystal therein. The method includes the step of applying a voltage pulse having an amplitude and a pulse width which exceeds a saturation voltage during a first half of a selecting term or a non-selecting term just before the selecting term to place the liquid crystal element in an "ON" or "OFF" state. The method also includes the step of applying the voltage pulse having a opposite polarity with respect to said voltage pulse and having an amplitude and a pulse width smaller than the threshhold voltage or exceeding the saturation voltage so that it is selected in order to maintain or to change the "ON" or "OFF" state. Further, it includes the step of rendering the average of a DC component which is applied to the liquid crystal element to zero by the method for applying a voltage pulse.

  • Patent number: 4701026
    Abstract: A method and circuits for multiplex driving of a multielement liquid crystal display device having a ferroelectric liquid crystal therein. The method includes the step of applying at least one selecting electric field pulse having an amplitude which exceeds a threshold value of optical response of the ferroelectric liquid crystal to each element during a selecting term. It further includes the step of applying at least one non-selecting electric field pulse having an amplitude which is no greater than threshold value to each element at a time other than the selecting term. The optical response of the ferroelectric liquid crystal is determined in accordance with waveforms of the selecting and non-selecting pulses. According to the invention the duration of the non-selecting pulses is much smaller than the time between selecting terms. The width of the non-selecting pulses is minimized.
