Abstract:
1. A method of driving a plasma display panel including a plurality of discharge cells for image display, wherein a field period includes a plurality of subfields, each subfield of the plurality of subfields including an initialization period, a writing period, and a sustain period, wherein the plurality of subfields of the field period includes (i) a subfield for performing an every-cell initialization operation, the every-cell initialization operation causing, in the initialization period of the subfield for performing the every-cell operation, an initial discharge in each of the plurality of discharge cells, and (ii) a subfield for performing a selective initialization operation, the selective initialization operation causing, in the initialization period of the subfield for performing the selective initialization operation, the initial discharge in any predetermined discharge cell of the plurality of discharge cells, wherein the method of driving the plasma display panel includes: wherein, in the every-cell initialization operation, the initial discharge is performed using a ramp voltage or a wave form having a change degree of 0.1 V/μs to 10 V/μs.
