Plate for a plasma panel with renforced porous barriers

Abstract

Tile comprising a substrate 10 coated with at least one array of electrodes 11 which is itself coated with an array of barrier ribs 17 made of a mineral material, the porosity of which is greater than 25%, comprising a porous base underlayer 18 which is inserted between the array of electrodes 11 and the array of barrier ribs 17 and which is made of a mineral material, the porosity of which is greater than 25%. Reinforced porous barrier ribs are obtained; advantageously, this tile does not include a specific dielectric layer; the number of manufacturing steps is limited and the tile can be manufactured entirely at low temperature.
