Abstract
A method of driving a Plasma Display Panel (PDP) having discharge cells formed where sustain electrodes cross address electrodes, the method including: processing an input image signal received from an external device and dividing the processed input image signal into frames, each frame including a plurality of subfields, each subfield having a corresponding gray scale weight; and supplying a voltage with a pulse waveform having a predetermined slope during a predetermined period in the subfield. The method further includes: determining a type of the input image signal; and if the image signal is a Phase Alternation Line (PAL) signal, adjusting the slope of the pulse waveform according to a temperature of the PDP.
