Patent ID: 7583242

Claim:
A plasma display panel (PDP), comprising: a plurality of address electrodes, and a plurality of scan electrodes and sustain electrodes arranged in pairs; a controller for: performing a gamma correction on an image signal, generating subfield data according to a compressed subfield generation table and outputting the subfield data as an address electrode driving signal, calculating an average signal level of the gamma-corrected image signal and correcting the average signal level of the gamma-corrected image signal according to an average signal level correction inverse curve which has an inverse characteristic with respect to a gamma correction curve used for performing the gamma correction, and outputting a sustain electrode driving signal and a scan electrode driving signal corresponding to a corrected average signal level; an address electrode driver for applying the address electrode driving signal to the address electrodes; a sustain electrode driver for applying the sustain electrode driving signal to the sustain electrodes; and a scan electrode driver for applying the scan electrode driving signal to the scan electrodes, wherein correction with the average signal level correction inverse curve maintains linear power consumption.
