Patent ID: 7768199

Claim:
A plasma display panel comprising a first plate and a second plate with a space between them filled with a discharge gas, said space being partitioned, by separating elements forming an array of barrier ribs, into a plurality of discharge cells arranged in rows and columns, said first plate comprising at least two arrays of coplanar electrodes called sustain electrodes, which are oriented along general directions that are parallel to each other and to said rows, said second plate comprising at least one array of electrodes called address electrodes, which are oriented along general directions that are parallel to each other and to said columns, said electrodes being placed so that, in each cell, an address electrode crosses an electrode of each sustain array, wherein each cell is subdivided into at least two trigger zones each located at an intersection of the address electrode with a sustain electrode and into a single coplanar discharge expansion zone that extends along the direction of the columns between the trigger zones, and wherein said array of barrier ribs comprises intercell separating elements, each separating two adjacent columns of cells, and is designed so that, in each cell belonging to a given column and a given row, the width of said coplanar discharge expansion zone, measured along said row between two adjacent intercell separating elements is less than the width of the trigger zones of said cell also measured along said row between the same two adjacent intercell separating elements.
