Abstract
A plasma display panel with an electrode composed of a metal layer (e.g., Fe and Ni) and a metal compound layer (e.g., alkaline earth metal oxide or sulfide, and rare earth metal hexaborides) which are formed by means of plasma spray coating. The plasma spray coating should be done at such a temperature that the metal or metal compound is in the molten state.
Claims11
A DC plasma display panel comprising first and second substrates defining a gas chamber therebetween;
- an ionizable gaseous medium within said chamber;
- an anode layer formed onto said first substrate;
- a cathode layer formed onto said second substrate;
- an emitter layer formed onto said cathode layer;
- said cathode layer, said emitter layer, and said anode layer being disposed within said chamber for ionizing said gaseous medium;
- said emitter layer being formed onto said cathode layer by plasma spray coating.
The plasma display panel of claim 11 wherein said cathode layer is made from a metal selected from the group consisting of Fe, Ni, W, Cu, Cr and Al.
The plasma display panel of claim 11 wherein said cathode layer is made from a metal alloy.
