Abstract:
A method for driving an plasma display panel having electrode pairs, each electrode pair defining a row having a plurality of cells, the method comprising:grouping the electrode pairs into first and second groups so that an electrode pair of one group is adjacent to at least one electrode pair of the other group; and, prior to an erase addressing, applying to electrode pairs belonging to one of the first and second groups, a first voltage which generates a discharge only in cells in a non-charged state and then a second voltage which generates a discharge in all the cells, and applying a third voltage to electrode pairs belonging to the other group and having a relationship with respect to the second voltage to generate a surface discharge in all the cells and thereby improve uniformity of charge, wherein at least a portion of a time during which the third voltage is applied overlaps with a time during which the second voltage is applied.
