ABSTRACT:
The present invention relates to a method and apparatus for driving a plasma display panel that can be driven at a low voltage and prevent undesired discharge from being generated under high temperature environment.A method and apparatus for driving a plasma display panel according to an embodiment of the present invention includes a first step of applying an initialization signal to the first and second electrodes to initialize cells, the initialization signal has at least one rising part where a voltage rises and at least one sustain part where the voltage is sustained; a second step of applying a scan signal to any one of the first and second electrodes, and data to the third electrode to select the cell; and a third step of alternately applying sustain signals to the first and second electrodes to carry out a display for the selected cell.
