Abstract:
1. A method of driving a plasma display panel, the plasma display panel including discharge cells, each formed at an intersection of a scan electrode and a sustain electrode, and a data electrode, the method comprising: dividing one field period into a plurality of sub-fields, each having an initializing period, writing period, and sustaining period; in the initializing periods of the plurality of sub-fields, performing one of all-cell initializing operation and selective initializing operation, wherein, in the all-cell initializing operation, initializing discharge is performed in all discharge cells for displaying an image, and, in the selective initializing operation, initializing discharge is selectively performed only in discharge cells subjected to sustaining discharge in a sub-field immediately before each of the sub-filed; and according to a signal of the image to be displayed, determining the initializing operation in the initializing period of each sub-field to be one of the all-cell initializing operation and the selective initializing operation.
