Abstract: A method of driving a plasma display panel for preventing a miswriting and a misfire as well as improving a contrast is disclosed. In the method, a first waveform is applied to sustain electrodes in an initialization period included in an initial sub-field of one frame. A second waveform is applied to the sustain electrodes in an initialization period of each of the remaining sub-fields following the initial sub-field.

Abstract: A method and apparatus for driving a plasma display panel for preventing and a spot misfire and a miswriting is disclosed. In the method, wall charges are formed at a discharge cell in an initial period. The discharge cell selects discharge cells in an address period. A wall charge control period is arranged between said initialization period and said address period. A wall charge distribution at the discharge cell is controlled in the wall charge control period. A sustain discharge is caused at discharge cells selected in said address period in the sustain period.

Abstract: A plasma display panel having an active area and a non-display area positioned at the outside of the active area wherein dummy electrodes positioned within said non-display area have a narrower gap between electrodes than sustain electrode pairs positioned within said active area. Accordingly, the plasma display panel has a narrower gap between electrodes of the dummy electrodes than the sustain electrode pair within the active area and has a narrow electrode width thereof, so that it can easily generate a discharge between the dummy electrodes well and reduce a generation of electric charges accumulated onto the dummy electrodes. As a result, the plasma display panel can prevent an abnormal discharge to improve a picture quality.
