摘要： A plasma display device is capable of creating a screen of high quality without generating half tone noise in the succeeding frames irrespective of the arrangement or the turn-on state of the subframes in a preceding frame that is being displayed. A picture of a frame is displayed on a plasma display device by combining a plurality of subframes SF1 and Sfn having different degrees of brightness. Each of the plurality of subframes SF1 and Sfn includes a totally writing and totally self-erasing period S1, an address period S2, a sustain discharge period S3, and a quiescent period S4 determined by a difference between the sum of the periods S1 to S3 and a period of a vertical synchronizing signal Vsync. A period S5 for imparting a discharge waveform different from the sustain discharge waveform applied across the electrodes is provided in the sustain discharge period S3 between the quiescent period S4 in the predetermined frame FM1 and the totally writing and totally self-erasing period S1 in the succeeding frame FM2.

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.

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.
