Abstract: Disclosed therein a method of driving a plasma display panel, which can improve display quality. The method is separately driven by a data driving period for supplying a driving waveform and a preliminary period for raising voltages for supplying the driving waveform up to a desired voltage, in order to display an image in each discharge cell, wherein a waveform supplied to electrodes during a sustain period of the data driving period is different from a waveform supplied to the electrodes during a sustain period of the preliminary period. The method does not create a sustain discharge during a sustain period and prevents an afterimage caused by a previous state when the PDP is turned on from being displayed, improving display quality. Moreover, charges within a discharge cell are eliminated by supplying a ground voltage to electrodes for 1 to 3 seconds, preferably 2 seconds, before a data driving waveform is supplied.

Abstract: The present invention provides a driving method suitable for a plasma display. The plasma display includes multiple scan electrodes, multiple sustain electrodes and multiple address electrodes, for example. Successive frames are adapted to be displayed in repeating reset periods, address periods and sustain periods by applying driving signals to the scan electrodes, sustain electrodes and address electrodes. The driving method is characterized in that before inputting driving signals or when interrupting driving signals, a wall-charge removing signal is applied to the scan electrodes to remove/reduce the residual wall charges around the scan electrodes and the sustain electrodes. As a result, the possibility of the plasma display generating erroneously discharging with strong light at the restarting state can be effectively reduced.

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.
