A plasma display panel is disclosed, which prevents luminance from being reduced, prevents error discharge from occurring due to crosstalk, and improves exhaust ability. The method may also include processing the first group of data items, by a data processing device, to provide a second group of data items having a second number of data items, and generating, by a data coding device, a correction data packet based on the second group of data items and information included in the feedback message, for correcting the transmission error. Thus, an amount of heat generated in the width direction can be regulated using a simple configuration at a reduced cost.
