Abstract
Disclosed is a plasma display panel, and an apparatus and method for driving the same. In the method of the present invention, an image signal is received and gamma-corrected according to a gamma correction curve. The gamma-corrected image signal is generated as subfield data according to a compressed subfield generation table. The average signal level of the image signal is calculated and correction according to an average signal level correction inverse curve is performed regarding the generation of the subfields for each gray level, and a sustain electrode driving signal and a scan electrode driving signal corresponding to the average signal level are output.
