Abstract:
1. A method for driving a plasma display panel having a scan electrode, a dielectric layer, and a protective layer, the method comprising: supplying a first driving signal to the scan electrode in a first subfield during a first reset period for initializing a discharge cell, a first address period for scanning the discharge cell, and a first sustain period for sustaining a discharge of the discharge cell; and supplying a second driving signal different from the first driving signal to the scan electrode in a second subfield during a second reset period having a different time duration from the first reset period, a second address period having a different time duration from the first address period, and a second sustain period having a different time duration from the first sustain period, wherein at least one of the dielectric layer or the protective layer comprise 1000 PPM (parts per million) or less of lead (pb), wherein a width of a first scan signal supplied to the scan electrode during the first address period of the first subfield is different from a width of the second scan signal supplied to the scan electrode during the second address period of the second subfield, and wherein a first frame includes the first subfield having the first scan signal, and a second frame includes the second subfield having the second scan signal, and a gray level weight of the first subfield is substantially equal to gray level weight of the second subfield.
