Abstract
Abstract A plasma display panel (PDP) of a planar discharger type which causes an auxiliary discharge and a display discharge in a single cell. The PDP includes anodes and cathodes formed in strips of different orientations and in different planes such that individual cells are formed which have a display anode, a display cathode, and an auxiliary anode.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
188 words
A plasma display panel, comprising: a back substrate; a front substrate; display cathodes formed in strips on said back substrate; a dielectric layer formed in strips on said back substrate; said dielectric layer strips intersecting said display cathode strips and covering said display cathode strips at the points of intersection; display anodes formed in strips on said dielectric layer strips; auxiliary anodes formed in strips on said front substrate, said auxiliary anode strips being of a different orientation than said display cathode strips; and a lattice type barrier rib formed on said back substrate and defining a plurality of discharge cells, said barrier rib having openings therein defining an electric charge particle path extending parallel to said auxiliary anode strips, said path also extending from cell-to-cell within said rib to thereby facilitate movement of electric charge particles from cell-to-cell within said rib, said front substrate being sealingly attached to said back substrate and said barrier rib to complete the formation of said discharge cells, each of said discharge cells containing portions of one of said display cathodes, one of said display anodes, and one of said auxiliary anodes.
Claim 2
Dependent Claim
188 words
A plasma display panel, comprising: a back substrate; a front substrate; display cathodes formed in strips on said back substrate; a dielectric layer formed in strips on said back substrate; said dielectric layer strips intersecting said display cathode strips and covering said display cathode strips at the points of intersection; display anodes formed in strips on said dielectric layer strips; auxiliary anodes formed in strips on said front substrate, said auxiliary anode strips being of a different orientation than said display cathode strips; and a lattice type barrier rib formed on said back substrate and defining a plurality of discharge cells, said barrier rib having openings therein defining an electric charge particle path extending parallel to said auxiliary anode strips, said path also extending from cell-to-cell within said rib to thereby facilitate movement of electric charge particles from cell-to-cell within said rib, said front substrate being sealingly attached to said back substrate and said barrier rib to complete the formation of said discharge cells, each of said discharge cells containing portions of one of said display cathodes, one of said display anodes, and one of said auxiliary anodes.
Claim 3
Dependent Claim
17 words
The plasma display panel of claim 1, wherein said front and back substrates are made of glass.
Claim 4
Dependent Claim
18 words
The plasma display panel of claim 2, wherein a phosphor layer is provided on said front glass substrate.
Claim 5
Dependent Claim
23 words
The plasma display panel of claim 1, wherein said display anode strips are of substantially the same orientation as said dielectric layer strips.
Claim 6
Dependent Claim
28 words
The plasma display panel of claim 4, wherein said auxiliary anode strips are of substantially the same orientation as said display anode strips and said dielectric layer strips.
Claim 7
Dependent Claim
18 words
The plasma display panel of claim 1, wherein said dielectric layer strips are of a substantially uniform thickness.
