Method for driving plasma display panel

A method for driving a plasma display panel, the method comprising:

• applying a first sustain pulse a first number of times if a display ratio of a first subframe falls within a first numerical value range, and applying a second sustain pulse having a waveform different from a waveform of the first sustain pulse a second number of times if the display ratio of the first subframe is larger than values of the first numerical value range, so that an image of the first subframe of a plurality of subframes to be replaced with a frame is displayed;
• and
• applying the first sustain pulse a third number of times if the display ratio of the first subframe falls within a second numerical value range different from the first
• numerical value range, and applying the second sustain pulse a fourth number of times if the display ratio of the first subframe is larger than values of the second numerical value range, so that an image of a second subframe, different from the first subframe, of the plurality of subframes is displayed.
