| 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 alternately by two and 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 with two adjacent scan electrodes of the plurality
of scan electrodes, each of the main discharge cells being formed of the display electrode pair and the data electrode,
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 and an even-numbered line writing time period,
a writing operation being performed in the main discharge cell having an odd-numbered scan electrode in the odd-numbered line
writing time period, a writing operation being performed in the main discharge cell having an even-numbered scan electrode
in the even-numbered line writing time period;
sequentially applying a scan pulse to an odd-numbered scan electrode and applying voltage to an even-numbered scan 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 scan electrode and the odd-numbered scan electrode to which the scan pulse has been applied;
and
sequentially applying a scan pulse to an even-numbered scan electrode and applying voltage to an odd-numbered scan 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 scan electrode and the even-numbered scan electrode to which the scan pulse has been applied.
