ABSTRACT:
A driving apparatus of a plasma display panel (PDP) and a method for displaying pictures on the plasma display panel, which are capable of increasing the ability to express a low gray scale. Common non-emitted sub-fields are detected, using picture signal data having the maximum level of the gray scale, of all input picture signal data within one frame of the input picture signal data. Sub-fields having higher weights are divided into a plurality of sub-fields having lower weights and the plurality of sub-fields having lower weights are rearranged as sub-fields for expression of gray scale, corresponding to the number of non-emitted sub-fields. In addition, the number of sustains corresponding to the rearranged sub-fields are generated.
