摘要： Driving apparatus including scanning electrodes and data electrodes, a liquid crystal assuming first and second optical states according to the polarity of a writing voltage applied thereto and disposed between the scanning and data electrodes, scanning-side and drive-side drivers, and a controller for controlling these drivers. The scanning-side drive supplies first and second scanning selections signals having mutually different voltage wave forms to the scanning electrodes so that the first and second scanning selection signals are applied alternately in respective vertical scanning periods. The data-side driver supplies data pulses to the data electrodes in synchronism with the first and second scanning selection signals so as to form one picture in at least four vertical scanning periods. The controller controls the scanning-side and data-side drivers so as to scroll each picture in at least four vertical scanning periods.

摘要： In a liquid crystal apparatus the scanning electrodes are applied with at least two scanning selection signals in at least two vertical scanning periods. The scanning selection signals comprise mutually different waveforms, each comprising a pulse of one or the opposite voltage polarity with respect to the level of a voltage applied to a scanning electrode when it is not selected. Data pulses are applied to the data electrodes in phase with the pulse. A writing voltage and a fore voltage are applied prior to the writing voltage formed by the combination of the pulse and a data voltage to a pixel on a scanning electrode during a selection period determined by application of the one or the opposite polarity to the scanning electrode. The fore voltage pulse has a polarity opposite to that of the writing voltage and an amplitude which is 1/2 or less of that of the writing voltage.

摘要： A liquid crystal display apparatus having scanning electrodes, data electrodes, and ferroelectric liquid crystal material placed between the scanning electrodes and the data electrodes. Scanning signals are applied sequentially to the scanning electrodes to select a scanning electrode. Data signals are applied in synchronization with the scanning signals to place a voltage at the intersection of the data electrode and the selected scanning electrode which will place the ferroelectric material at the intersection into the desired optical state. The scanning signals and the data signals are such that pixels located at the intersection of the non selected scanning electrodes and data electrodes receive an AC voltage superimposed onto a DC voltage. Pixels on selected scanning electrodes may also receive the AC voltage superimposed onto the DC voltage. The DC voltage has its polarity inverted with every vertical scanning period.

摘要： In an optical modulation device, a matrix of pixels are formed at intersections of scanning lines and data lines so as to assume either a first optical state or a second optical state. In a first phase, a voltage V.sub.R of one polarity is applied to the pixels on a selected scanning line to provide the first optical state. In a second phase, the pixels on the selected scanning line are selectively supplied with a voltage V.sub.B.sup.2 of the other polarity inverting the first optical state to the second optical state or a voltage V.sub.B.sup.1 of the other polarity not changing the first optical state. Herein, the minimum of the durations of single-polarity voltages is defined as .DELTA.t, and a voltage at which the optical conversion from the first to the second optical state or vice versa is saturated based on the minimum application time .DELTA.t is defined as a saturation threshold voltage Vsat. Then, the application time of the voltage V.sub.R exceeds the minimum application time .DELTA.t, and a pixel supplied with the voltage V.sub.B.sup.1 in the second phase is supplied with a voltage V.sub.R, the maximum amplitude of which does not exceed the saturation threshold voltage Vsat in terms of absolute values, in the first phase.

摘要： A display apparatus features an optical modulation device including a plurality of pixels and a pair of electrodes to which a voltage is applied, and an illumination device for illuminating the optical modulation device instantaneously and successively with a plurality of monochromatic lights of different colors in a frame period to provide a full-color image in combination with application of the voltage to the electrodes of the optical modulation device thereby effecting a full-color display over a succession of the prescribed period. A controller divides each frame period into two periods including a first period for displaying a full-color image at each pixel and a second period immediately after the first period and for placing the optical modulation device in a non-display state, thus effectively suppressing an after image phenomenon adversely affecting a full-color image display in a subsequent frame period.
