(54) Plasma display and driving method


(57) The present invention relates to a plasma display and a driving method thereof. In the driving method, to prevent a flickering effect in a phase alternating by line (PAL) method, a plurality of subfields divided from one frame are grouped into at least three subfield groups. In addition, since the number of sustain pulses applied to one frame is large when an automatic power control level is set to be less than a reference value, the plurality of subfields divided from one frame are grouped into two subfield groups to sufficiently obtain a time for applying the sustain pulses.
