    摘要： A ferroelectric liquid crystal cell is controlled by applying a strobe pulse (Vs) and a data pulse (Vd1, Vd2, Vd3) to the cell, the magnitude of the data pulse being modulated in order to control the resultant pulse applied to the cell. The resultant pulse comprises a pre-pulse on one polarity and a main pulse of the opposite polarity. When applied to a liquid crystal cell of stepped thickness, the application of data pulses of different magnitudes switches regions of different thicknesses of the cell so as to provide grey level capability.

    摘要： A liquid crystal device is constituted by a first electrode substrate having thereon a group of first electrodes, a second electrode substrate having thereon a group of second electrodes intersecting the first electrodes, and a liquid crystal disposed between the first and second electrode substrates so as to form a pixel at each intersection of the first and second electrodes. The liquid crystal device is driven for gradational display by selecting and writing in a pixel plural times in one frame of display for gradational display, wherein a second and a subsequent writing among the plural times of writing is performed by applying a bipolar pulse of identical shapes in positive and negative polarities.

    摘要： A display apparatus is constituted by a display device including a plurality of scanning lines, a plurality of data lines intersecting the scanning lines, and a pixel formed at each intersection of the scanning lines and data lines and showing plural display states depending on signals applied to an associated scanning line and an associated data line. The display device is driven by applying a selection signal to the scanning lines and applying to the data lines data signals for causing prescribed display states at the pixels in association with the selection signal. Further, at least one scanning line in a nonselected state is supplied with a dummy signal for temporarily changing display states of pixels on the at least one scanning line, whereby flickering on the display device is suppressed. The display apparatus is also applicable to gradational display.
