Abstract
The invention provides a driving apparatus for a plasma display panel which performs optimization of a discharge voltage automatically and achieves reduction of the number of steps for adjustment and reduction of a secular change of the display quality. The driving apparatus for a plasma display panel includes a discharging situation detection section for detecting a variation of a state of each of cells of the plasma display panel which has an influence on a display quality such as a temperature, an elapsed time or the like of the cell, and a control section for calculating an optimum driving voltage for a scanning electrode or a write electrode of the cell in response to the discharging situation of the cell detected by the discharging situation detection section and causing the optimum driving voltage to be applied to the scanning electrode or the write electrode of the cell to cause the cell to discharge.
