ABSTRACT:
The present invention relates to a plasma display apparatus and method for driving the same. According to the present invention, the plasma display apparatus includes a plasma display panel having a first electrode and a second electrode, and a third electrode which is crossed with the first electrode and the second electrode, a scan driving unit for applying a sustain pulse, which rises from a first bias voltage of the negative polarity up to a sustain voltage, to the first electrode, and a sustain driving unit for applying a sustain pulse, which rises from a second bias voltage of the negative polarity up to a sustain voltage, to the second electrode in an alternate manner with the sustain pulse applied by the scan driving unit. Further, in the method for driving the plasma display apparatus, when a driving pulse is applied to first, second and third electrodes in a reset period, an address period and a sustain period, and an image is displayed with frames by a combination of one or more sub-fields, in the sustain period, a sustain pulse that rises from a first bias voltage of the negative polarity up to a sustain voltage is applied to the first electrode, and a sustain pulse that rises from a second bias voltage of the negative polarity up to a sustain voltage is applied to the second electrode in an alternate manner with the sustain pulse that rises from the first bias voltage of the negative polarity up to the sustain voltage.
