Abstract
The present invention relates to a driving method of a plasma display panel for improving a picture quality. The driving method of a plasma display panel in which an nth frame having a first brightness weighting value and a (n+1)th frame having a brightness weighting value different from the first brightness weighting value are alternatively arranged every vertical synchronous signal to display a certain image, wherein one frame period of the nth frame or the (n+1)th frame is variably set such that a brightness expression period can be identically set at the nth frame and the (n+1)th frame.
