Patent ID: 7995006

Claim:
A method of driving a plasma display panel including a plurality of discharge cells including a display electrode pair having a scan electrode and a sustain electrode, wherein one field is formed of a plurality of sub-fields each of which includes an initializing period during which initializing discharge takes place in the discharge cells, and an addressing period during which address discharge takes place in the discharge cells, and a sustained period where sustain discharge takes place in the discharge cells, the method comprising the steps of: setting each one of the sub-fields as one of an entire initialization sub-field and a selective initialization sub-field, wherein in the entire initialization sub-field, the initializing discharge takes place during the initializing period at all discharge cells that are involved in displaying a video, and in the selective initialization sub-field, the initializing discharge takes place during the initializing period at a selective discharge cell, wherein the sustain discharge has taken place in a sub-field immediately before the initializing period: controlling an initializing voltage which generates initializing discharge in the entire initialization sub-field when the entire initialization sub-field is switched over to the selective initialization sub-field or vice versa; and setting an initializing voltage of at least one of the entire initialization sub-fields in a field immediately before a field, in which a number of entire initialization sub-fields is increased, higher than an initializing voltage of at least two of the entire initialization sub-fields in a field immediately after a field in which the number of the entire initialization sub-fields has been increased.
