摘要： A method of driving a plasma display panel having plural, parallel sustain and scan electrodes, corresponding to respective display lines, and plural address electrodes in opposed relationship and electrically isolated with respect to the sustain and scan electrodes and intersecting same so as to form respective discharge cells at the intersections. The method produces an interlaced display by generating discharges in selected discharge cells, in odd and even fields, between respective, different sets of the sustain and scan electrodes. Each of the odd and even fields includes a reset period in which a reset discharges are produced in the discharge cells to establish a uniform charge distribution therein, an address period in which write discharges are produced in selected discharge cells in accordance with display data and a sustain discharge period in which sustain discharge pulses are produced in the written discharge cells to establish a glow discharge, for display during the respective periods. Potential differences between the respective sets of the sustain and scan electrodes of the odd and even fields are held below a discharge initiating voltage level, thereby avoiding the otherwise occurring problem of contrast drop.

摘要： A plasma display panel and driving method thereof perform addressing at a high speed and a low voltage without deteriorating contrast. Priming electrodes forming priming cells are located outside but adjacent a display area. Glow occurring in the priming cells is intercepted. When priming discharge is induced at a reset step, voltages lower than a discharge start voltage are applied to first (X) and second (Y) electrodes and third (address) electrodes respectively. Despite the voltages being lower than the discharge start voltage, once discharge is induced in the priming cells, discharge starts in adjoining cells. The discharge then spreads successively over all the cells, thus inducing discharge in all the cells. Consequently, wall charge is produced in all the cells.

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 high-definition large-screen panel capable of realizing full-color high-luminance display without the restrictions that have been imposed on luminance (number of sustaining discharges) and gray-scale display or the number of display lines in the past has been disclosed. The panel includes a plurality of cells that selectively discharge to glow. According to a driving method for a plasma display panel, during an addressing period, a voltage is applied selectively to cells according to display data so that a charge proportional to display data can be stored in each cell. During a sustaining discharge period, a sustaining discharge voltage is applied to the plurality of cells so that cells in which given charges are stored can discharge to glow. In the driving method, during the addressing period, a plurality of different voltages associated with gray-scale levels to be displayed are applied to the cells so that a quantity of charge proportional to an applied voltage can be stored in each cell. During the sustaining discharge period, the strength of an applied voltage is varied.

These steps are carried out during the reset period.

摘要： In a sustain operation in an ALIS PDP device, a combination in which a basic first waveform and a second waveform in which a discharge peak is separated are mixed is applied. In the combination, the probability that the second waveform occurs successively is sufficiently reduced to less than 20%, and the number of times of sustain discharges of various intensities is made equal in the lines to be driven. By this means, the 2L nonuniformity can be prevented, and the deterioration of Vsmin can be reduced.
