Plasma display device and driving method thereof

A method of driving a plasma display device including a display panel having a plurality of scan electrodes, a plurality of sustain electrodes, a plurality of discharge cells and a plurality of discharge spaces, the method comprising:

• applying a rising ramp signal rising with a slope to the scan electrodes,
• applying a falling ramp signal falling with a slope from a peak value of the rising ramp signal to the scan electrodes, and
• generating priming discharge in the discharge spaces between adjacent ones of the scan electrodes, wherein:
• the discharge cells are partitioned by horizontal and vertical barrier ribs on the display panel,
• on adjacent ones of the discharge cells, corresponding ones of the scan and sustain electrodes are alternatively arranged in a scan-sustain-sustain-scan electrode or a sustain-scan-scan-sustain electrode manner,
• the discharge spaces are between the horizontal barrier ribs of two adjacent rows of the discharge cells, and
• adjacent ones of the scan electrodes are electrically connected in parallel, and spaced apart from each other in a region above the respective discharge space.
