| 1. A driving method of a plasma display panel,
the plasma display panel comprising:
a first substrate;
a plurality of display electrode pairs that are disposed on the first substrate and formed of scan electrodes and sustain
electrodes, the scan electrodes and the sustain electrodes being arranged in parallel;
a second substrate faced to the first substrate through a discharge space;
a plurality of data electrodes disposed on the second substrate and in a direction crossing the display electrode pairs; and
a barrier rib disposed between the first substrate and the second substrate so as to separate main discharge cells for causing
main discharge and priming discharge cells for causing priming discharge,
the driving method of the plasma display panel comprising:
forming one field including a plurality of subfields having an initialization time period, a writing time period, and a sustaining
time period;
dividing the writing time period into an odd-numbered line writing time period in which a writing operation is performed in
the main discharge cell corresponding to an odd-numbered scan electrode, and an even-numbered line writing time period in
which a writing operation is performed in the main discharge cell corresponding to an even-numbered scan electrode;
sequentially applying a scan pulse to an odd-numbered scan electrode and applying voltage to an even-numbered sustain electrode
in the odd-numbered line writing time period, the voltage being used for causing priming discharge in the priming discharge
cell between the even-numbered sustain electrode and the odd-numbered scan electrode to which the scan pulse has been applied;
sequentially applying a scan pulse to an even-numbered scan electrode and applying voltage to an odd-numbered sustain electrode
in the even-numbered line writing time period, the voltage being used for causing priming discharge in the priming discharge
cell between the odd-numbered sustain electrode and the even-numbered scan electrode to which the scan pulse has been applied;
and
applying sustaining pulse voltages having a substantially equal phase to an odd-numbered scan electrode and an even-numbered
sustain electrode, and applying sustaining pulse voltages having a substantially equal phase to an even-numbered scan electrode
and an odd-numbered sustain electrode, in the sustaining time period.
