Abstract
In a conventional method of driving a plasma display panel, for example, an auxiliary discharge is executed between an A electrode and a Y electrode to improve light-emission efficiency of a display discharge. However, since a phosphor layer is present between the A electrode and the Y electrode, the phosphor layer is exposed to a discharge, whereby there is a problem that its characteristic deteriorates. A method of driving a plasma display panel having a structure, in which at least three display electrodes X, Y, and Z used for a display discharge are provided to a display cell and no phosphor layer is formed between said display electrodes and a discharge space, the method comprising the steps of: varying a potential of at least one display electrode Z of said display electrodes during said display discharge; and making a potential of said at least one display electrode Z at a time of starting said display discharge different from that at a time of ending said display discharge.
