<p>The present invention relates to a driving apparatus for supplying a driving signal to a plasma display panel, and a plasma display apparatus employing the same. A reset signal supplied during a reset period of a first subfield of a plurality of subfields includes a first rising period where a voltage rises up to a first voltage, and a first maintain period where the first voltage is maintained. A reset signal supplied during a reset period of a second subfield includes a second rising period where a voltage rises up to a second voltage lower than the first voltage, and a second maintain period where the second voltage is maintained. The second voltage is higher than a sustain voltage. If it is sought to reset discharge cells of a PDP in a reset period, a signal whose voltage gradually rises up to a voltage higher than the sustain voltage is applied to a scan electrode. Accordingly, wall charges of the scan electrode for addressing can be controlled effectively, the highest voltage of the reset signal can be lowered and, therefore, driving margin can be secured. Further, since the maintain period of the highest voltage is included, stabilized discharge can be generated irrespective of variation of an APL of a display screen.</p> |
