METHOD OF DRIVING PLASMA DISPLAY PANEL AND PLASMA DISPLAY APPARATUS USING THE METHOD
First Claim
1. A method of driving a plasma display panel (PDP) during a field comprising a plurality of subfields, each subfield comprising a reset period, an address period, and a sustain period, the PDP comprising scan electrode lines, sustain electrode lines parallel to the scan electrode lines, and address electrode lines crossing the scan electrode lines and the sustain electrode lines at a plurality of cells, the method comprising:
- initializing wall charges of the cells during the reset period;
generating a discharge in selected cells of the plurality of cells during the address period to enable a sustain discharge in the selected cells;
generating the sustain discharge in the selected cells during the sustain period; and
applying an erase pulse to the scan electrode lines early in the sustain period.

Abstract
A method of driving a plasma display device, having a time-divisionally driven gray scale utilizing a reset period in which wall charges of all cells of a plasma display panel (PDP) are initialized, an address period for enabling a sustain discharge by generating a weak discharge in selected cells, and a sustain period in which the sustain discharge is generated in the selected cells. Further, an erase discharge is generated in all the cells of the PDP early in the sustain period.
