Abstract
A plasma discharge method and a plasma display using the same. In the method, a sustain discharge uses a facing surfaces discharge and a surface discharge after an address discharge. The discharges occur in separate discharge areas, and priming particles generated by the discharges are exchanged. Thus, the stability and the efficiency of the sustain discharge increase, and a gap for the address discharge decreases to lower a breakdown voltage.
