摘要： In a plasma display and a method of driving a plasma display, a discharge is generated in a sustain period since a first voltage is supplied to a scan electrode and a second voltage lower than the first voltage is supplied to a sustain electrode. Accordingly, a discharge current flows since wall charges are formed on the scan and sustain electrodes as a result of the discharge. When the discharge current flows, a third voltage lower than the first voltage and higher than the second voltage is supplied to the sustain electrode while the first voltage is supplied to the scan electrode. In addition, when another discharge current flows since a sustain discharge is generated by supplying the first voltage to the sustain electrode and suypplying the second voltage to the scan electrode, the third voltage is supplied to the scan electrode while the first voltage is supplied to the sustain electrode.
