Abstract

Abstract An improved plasma display panel is disclosed, the improvement comprising: a resistance layer stacked on the surface of a trigger electrode in such a manner that the surface of the resistance layer should be exposed to a discharge space filled with discharge gas, characterized in that the trigger electrode is unitized into a single piece so that the whole surface of the resistance layer should be matched with the whole surface of the trigger electrode. The device of the present invention is easy to manufacture because the dielectric which is complicated and has fastidious conditions is removed, and low cost metals as the material of the electrodes can be adopted, thus making it also possible to save the manufacturing cost.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 112 words
A plasma display panel comprising: a front plate and a rear plate spaced to provide a discharge space, a plurality of cathodes and anodes arranged between said plates in an X-Y matrix, said anodes being in proximity to said front plate and said cathodes being in proximity to said rear plate, a trigger electrode which triggers main discharges between said cathodes and said anodes, said trigger electrode being between said cathodes and said rear plate, a resistance layer on a surface of said trigger electrode and positioned such that a surface of said resistance layer is exposed to the discharge space, and an insulation layer between said resistance layer and said cathodes.
Claim 2
Dependent Claim 112 words
A plasma display panel comprising: a front plate and a rear plate spaced to provide a discharge space, a plurality of cathodes and anodes arranged between said plates in an X-Y matrix, said anodes being in proximity to said front plate and said cathodes being in proximity to said rear plate, a trigger electrode which triggers main discharges between said cathodes and said anodes, said trigger electrode being between said cathodes and said rear plate, a resistance layer on a surface of said trigger electrode and positioned such that a surface of said resistance layer is exposed to the discharge space, and an insulation layer between said resistance layer and said cathodes.
Claim 3
Dependent Claim 34 words
