ABSTRACT:
A method for driving a plasma display panel is provided in which wasteful power consumption is reduced and ion bombardment that may deteriorate cells is suppressed for a long life of cells. A ratio of lighting that is a ratio of the number of cells to be lighted to a total number of cells is detected in accordance with display data that determine contents of addressing. In accordance with the detected ratio of lighting, a waveform of a voltage pulse that is applied in the sustaining step for displaying the corresponding display data is changed so that a gradient of the voltage change at a leading edge becomes smaller for a large value of the ratio of lighting than for a small value of the same.
