Abstract:
Disclosed is a method of driving a plasma display panel. In this method, one field corresponding to one image is divided into a plurality of sub-fields, and at least one second sub-field is arranged after a first sub-field. In the first sub-field, the method comprises a first step of forming wall charges with negative polarity near the scanning electrode and forming wall charges with positive polarity near the common electrode and the data electrode; a second step of adjusting an amount of the wall charges with negative polarity near the scanning electrode and an amount of the wall charges with positive polarity near the common electrode and the data electrode; a third step of generating a writing discharge in a selected display cell of the display cells; a fourth step of generating light emission for display; and a fifth step of erasing a part of the wall charges in the display cell which emits light in the fourth step. In the second sub-field, the method comprises the same steps as the third, fourth and fifth steps. A potential difference between a scanning electrode and a common electrode in each of the fifth steps in the first and second sub-fields is set to be smaller than a potential difference between a scanning electrode and a common electrode in each of the third steps in the first and second sub-fields.
