Abstract: The invention concerns faceplate, more particularly for plasma display, comprising a substrate on which is provided at least one electrode, made of conductive material consisting of a metal alloy based on aluminium and/or zinc having a melting point higher than 700° C.; the electrode is designed to be coated with a dielectric layer. Thus, the harmful effects derived from reactions of the electrode materials with those of the dielectric layer are limited, in particular when said layer is being cured.

Abstract: The present invention relates to a plate, more particularly for plasma display panels, comprising a substrate 10 on which at least one electrode 21, made of a conducting material consisting of an aluminium-based and/or zinc-based metal alloy having a melting point above 700° C., is produced; the electrode is intended to be covered with a dielectric layer.

Abstract: The composition for a black matrix, which does not include a mineral binding and/or sintering agent, preferably contains a pigment chosen from: i) an iron chromium aluminium mixed oxide, ii) an iron chromium nickel cobalt mixed oxide and iii) an iron chromium cobalt aluminium mixed oxide or a mixture of iron, chromium, cobalt and aluminium oxides. The invention also relates to a plasma display panel comprising a first tile (2) and a second tile (4) facing each other, enclosing a discharge space, and an array of discharge cells at the intersection of electrodes covered with a dielectric layer (6, 8, 12, 14), at least one of the tiles having a black matrix (30) embedded beneath a dielectric layer (6), the black matrix (30) consisting of an opaque material, at least part of which is incorporated into the said dielectric layer (6).

Abstract: The invention applies to plasma display panels consisting of two facing plates enclosing a discharge space and comprising an array of discharge cells (X1, X2, . . . , X5, etc.). A display panel according to the invention has at least one porous layer which contains less than 10% of a hardening agent. The porous layer is either a barrier layer or a gettering layer.

Abstract: A plasma panel includes a front faceplate and a rear faceplate between which are constituted cells. The two faceplates are assembled together by bracing means which determine the distance between the two faceplates. The plasma panel further includes barriers arranged between the two faceplates, and serving in particular to prevent the discharges of one cell from extending to the other neighboring cells. The invention is characterized in that the height of the barriers is less than the distance between the faceplates. This arrangement provides a conditioning effect to the cells to thereby enabling them to be activated more speedily. The invention is in particular applicable to plasma panels using luminophores of different colours.
