Abstract:
1. A method for driving a plasma display panel in which a discharge cell is formed at an intersection of a scan electrode, a sustain electrode, and a data electrode, the method comprising: setting an all-cell initializing field and a selective-cell initializing field at a ratio of 1:N (where, N takes an integer of 1 or greater, the all-cell initializing field is a field that contains at least one sub-field having the all-cell initializing operation, and the selective-cell initializing field is a field that is formed of sub-fields having the selective-cell initializing operation only); and extending, at least in one sub-field, a width of the scan pulse applied in the selective-cell initializing field according to the N, each initializing period of the plurality of sub-fields carries out any one of the all-cell initializing operation for generating the initializing discharge in all the discharge cells where an image is to be displayed and the selective-cell initializing operation for selectively generating the initializing discharge in the discharge cells where the sustain discharge has occurred in the previous sub-field.
