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.

Plasma discharge method and plasma display using the same

A design for a plasma display panel (PDP). The novel PDP has two separate layers of fluorescent material. One layer of fluorescent material can generate long wavelength from VUV rays and the other fluorescent layer can convert either of VUV or long wavelength ultraviolet rays into visible rays. Such a PDP improves the luminance efficiency by more efficiently using the UV and VUV rays generated during plasma discharge.
