摘要： A plasma display panel (PDP) and a method for driving the PDP. An ON/OFF pattern of an externally-inputted image signal is checked to sense a sustained discharge occurring in discharge cells respectively corresponding to scan electrodes included in a particular one of multiple scan electrode groups over a predetermined time. A control operation is carried out in response to the sensing of the sustained discharge to allow a discharge to occur in discharge cells respectively corresponding to scan electrodes included in the scan electrode groups other than the particular scan electrode group.

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： Disclosed is a reset waveform of a plasma display panel. A rising or falling voltage is applied rapidly enough to cause an intense discharge in a reset interval. The electrodes are then floated to reduce the voltage applied into a discharge space during the discharge to cause a self-quenching of the discharge, thereby precisely controlling wall charges.
