    摘要： A method for driving a display panel to produce an efficient sustain discharge is provided. In one embodiment, the display panel includes a plurality of scanning electrodes that are driven by a sustain discharge signal. A corresponding plurality of common electrode groups is driven individually by different sustain discharge signals. Sustain discharge is performed by alternately applying high level sustain pulses to each the plurality of scanning electrodes and each the plurality of common electrode groups. Sustain pulses with a high level are applied sequentially to each the plurality of common electrode groups in time intervals between the sustain pulses with the high level applied to the plurality of scanning electrodes. Therefore, it is possible to maintain a duty rate of a sustain discharge signal near 50% while reducing a peak value of currents generated upon sustain discharge driving, thereby achieving stable sustain discharge.

    摘要： In a method of driving a discharge display panel, each subfield may include a first address period, a first display-sustain period, a second address period, and a second display-sustain period. In the first address period, a predetermined wall voltage may be generated in isplay cells selected from the display cells of the first display electrode-line pair group. In the first display-sustain period, display-sustain discharge may occur during a time proportional to a gray scale weight of each of the subfields in the selected display cells of the display cells of the first display electrode-line pair group when the first address period has elapsed. In the second address period, a predetermined wall voltage may be generated in display cells selected from the display cells of the second display electrode-line pair group when the first display-sustain period has elapsed. In the second display-sustain period, display-sustain discharge may occur during a time proportional to a gray scale weight of each of the subfields in the selected display cells of the display cells of the first and second display electrode-line pair groups when the second address period has elapsed.

    摘要： A plasma display panel (PDP) and a method for driving the PDP are described. A falling pulse waveform including alternately repeated voltage falling periods and floating periods that have a first mean slope and another falling pulse waveform including alternately repeated voltage falling periods and floating periods that have a second mean slope gentler than the first mean slope may be applied to sustain electrodes. The first and second slopes may be controlled by controlling the floating time or voltage falling range. In accordance with the present invention, it may be possible to apply pulse waveforms having diverse slopes through a simple driving circuit by floating a voltage charged in or discharged from a panel capacitor.

    摘要： A PDP driving method. A falling ramp voltage is applied to a scan electrode so as to reset a state of wall charges of a discharge cell during a reset period. In this instance, a sustain electrode is maintained at a high voltage during an initial period for applying the falling ramp voltage, and the voltage at the sustain electrode is reduced to a normal voltage at a latter part of the period for applying the falling ramp voltage. Accordingly, the voltage applied to an address electrode is reduced in an address period since an erased amount of the wall charges of the address electrode is reduced during the reset period.

    摘要： A PDP driving method. When a first sustain pulse is applied to a scan electrode during a sustain period, an address electrode is biased by a positive voltage, or the address electrode is biased. Therefore, when a large amount of wall charges are formed on the address and scan electrodes by address discharging during an address period, no main discharge is generated since a high potential of the address electrode is formed in the sustain period.
