Patent ID: 6879104

Claim:
Front tile for a plasma display panel provided with an array of pairs of sustain electrodes leaving between them a sustain discharge gap extending along the internal surface of this tile, the adjacent sustain discharge regions for the different primary colours being grouped together in pixels, in which each sustain electrode of a pair comprises: a continuous ignition conductor, one of the edges of which faces the other electrode of the pair and forms, in the event of a sustain discharge between the electrodes of the said pair, an ignition front of this discharge, a continuous conductor for distributing the discharge current, called a bus, placed facing the other edge of the ignition conductor, without any overlap and without any direct contact with the latter, means for electrically connecting the ignition conductor to the bus, wherein each sustain electrode has, in at least one sustain discharge region for each pixel, means for spreading the discharge in a general direction approximately perpendicular to the said ignition front, these means being independent of the said electrical connection means.
