Abstract:
1. An apparatus for driving a plasma display panel, the apparatus having scan, sustain, and address electrodes so as to be driven in accordance with reset, address, and sustain periods for time, the apparatus comprising: a scan driving integrated circuit supplying the scan electrode with inputted positive and negative voltages; a first scan voltage supplying unit supplying the scan driving integrated circuit with a positive voltage higher relatively than a lowest voltage level of a reset discharge; a second scan voltage supplying unit supplying the scan driving integrated circuit with a negative voltage lower relatively than the lowest voltage level of the reset discharge; and an energy recovery unit charging a voltage recovered from the scan electrode in the sustain period so as to discharge the charged voltage, wherein the negative voltage applied to the scan electrode during the address period is less than a lowest level of a voltage applied to the scan electrode during the sustain period, and the positive voltage applied to the scan electrode during the address period is greater than a lowest level of a voltage applied to the scan electrode during the sustain period.
