Abstract:
A method of driving an AC type plasma display panel including a full screen write step of applying a write voltage higher than a discharge starting voltage to respective cells constituting a screen of the plasma display panel to cause a discharge in the respective cells for accumulation of wall charges therein, the method comprising:a write preparation step of applying an auxiliary write voltage lower than the discharge starting voltage and having the same polarity as that of the write voltage to the respective cells to cause a discharge in a charged cell having wall charges accumulated before the application of the auxiliary write voltage for inversion of the polarity of a wall voltage in the charged cell, said write preparation step being performed prior to the full screen write step,wherein the application of the write voltage in the full screen write step is performed within a period during which space charges resulting from the discharge caused in response to the application of the auxiliary write voltage remain in the charged cell, so that a priming effect of the space charges can be utilized, thereby minimizing a difference in discharge intensity between the charged cells and uncharged cells.
