ABSTRACT:
A method and apparatus for driving a plasma display panel that automatically controls power using an average signal level that is compensated based on a difference between power consumption at red (R), green (G), and blue (B) discharge cells. The method includes calculating R, G, and B average signal levels, calculating a compensated average signal level using the R, G, and B average signal levels and R, G, and B weights, and controlling the number of discharges for each frame, which is in inversely proportional to the compensated average signal level. The R, G, and B weights are set at a value that reduces a difference between power consumption at the R, G, and B colored discharge cells when displaying the R, G, and B colors in a case where the R, G, and B average signal levels are equal to each other.
