Title:
COPLANAR DISCHARGE FACEPLATES FOR PLASMA DISPLAY PANEL PROVIDING ADAPTED SURFACE POTENTIAL DISTRIBUTION
Document Type and Number:
WIPO Patent Application WO2004001786
Kind Code:
A3
Abstract:
The invention concerns a faceplate comprising, for each discharge zone, at least two electrode elements having an axis of symmetry Ox and which are adapted such that the surface potential V(x) measured at the dielectric layer surface covering said elements increases, away from the edge of the discharge elements, continuously or discontinuously, without decreasing portion, when a constant potential difference is applied between the two electrodes serving said discharge zone, thereby substantially enhancing the panel luminous efficacy.
