摘要： A display apparatus is constituted by disposing a ferroelectric liquid crystal between a group of scanning electrodes and a group of data electrodes constituting an electrode matrix, and by arranging drive means including a first means for applying a scanning signal to the scanning electrodes and a second means for applying data signals to the data electrodes in synchronism with the scanning signal. The drive means are so controlled as to divide the scanning electrodes into a plurality of blocks each comprising a plurality of scanning electrodes and select the scanning electrodes with skipping of at least one scanning electrode apart so that starting scanning electrodes in neighboring blocks from which the skipping-selection of scanning electrodes is started in each block of the scanning electrodes have mutually different positional ranks respectively in the neighboring blocks, whereby flickering is effectively suppressed either it is caused by scanning drive or by repetition of black and white signals while the observability of a motion picture is retained.

摘要： A liquid crystal device of the active matrix-type having two-dimensionally arranged pixels along rows and columns is driven frame by frame. In each frame operation, a scanning selection period (T G ) for each selected row is divided into a first period (t 1 ) and a second period (t 2 ). In t 1 of a current frame (T F2 ), a reset pulse is applied to a pixel concerned, and the reset pulse is set to have an absolute value of voltage identical to and a polarity opposite to those of a writing pulse voltage applied to the pixel in the previous frame (T F1 ). Then, in t 2 of the current frame (T F2 ), the pixel is supplied with a writing pulse depending on a prescribed display state of the pixel for the current frame. As a result, the reset period is shortened to favor a high-speed display and a higher resolution display.

摘要： A liquid crystal device is constituted by a pair of oppositely disposed substrates (11,12) each provided with an alignment control layer (15,16), and a liquid crystal layer (17) comprising a liquid crystal material and disposed between the substrates with a spacer member (18). In the device, the spacer member (18) has an electrical conductivity larger than that of the liquid crystal material. Further, the liquid crystal layer containing the spacer member has a first resistance in a direction of a normal to the substrates in a prescribed temperature range substantially lower than a second resistance of a corresponding liquid crystal layer, in the identical direction, consisting only of the liquid crystal material and having the identical plane area and thickness. The liquid crystal device is effective in providing an improved drive margin in a wide temperature range while suppressing a DC offset voltage component applied to the liquid crystal layer.

摘要： A liquid crystal device of the type including a pair of substrates having thereon a group of scanning electrodes and a group of data electrodes, and a chiral smectic liquid crystal disposed between the substrates so as to form a pixel at each intersection of the scanning electrodes and the data electrodes, is driven by a driving method causing less crosstalk. The driving method includes the steps of sequentially applying a scanning selection signal to the scanning electrodes, and applying data signals to the data electrodes in synchronism with the scanning selection signal. The scanning selection signal includes a writing pulse having a pulse width ΔT for determining an optical state of the chiral smectic liquid crystal in cooperation with a data signal. Each data signal includes a data pulse for determining an optical state of the chiral smectic liquid crystal in cooperation with the writing pulse. A plurality of data signals are each designed to have a waveform determined based on a combination of data applied to pixels on at least two consecutively selected scanning electrodes. At least one of said plurality of data signals include an auxiliary pulse having a pulse width shorter than ΔT.

摘要： A liquid crystal display device is constituted by a pair of electrode plates each having a plurality of elongated electrodes, and a layer of ferroelectric liquid crystal disposed between the electrode plates so as to form a pixel at each intersection of elongated electrodes disposed respectively on the pair of electrodes plates. At least one electrode plate is provided with an unevenness at each pixel so as to form a cell thickness gradient (α₁α₂), within each pixel, and at least one electrode plate is provided with at least three types of color filters each corresponding to a pixel. Further, each color filter and/or each pixel (R,G,B) is set to have an area and/or a shape varying depending on a local cell thickness so that light quantities or sensible light quantities transmitted through the respective filters and the liquid crystal layer are identical to each other regardless of the type of color filter. A similar pixel pattern deformation is effective for providing a linear T (transmittance) - log V (voltage) characteristic. Color pixels pattern deformation may preferably be effected in a complementary manner with respect to different colors.
