The diode comprises: A high-yield diode is thus obtained in a particularly economical way.

Light-emitting organic diode comprising not more than two layers of different organic materials

An organic light-emitting diode comprising a substrate, an organic light-emitting layer arranged between a first electrode and a transparent and semi-reflecting second electrode with a multilayer structure subdivided into:

Organic light-emitting diode with transparent multilayer electrode

Tile comprising a substrate coated with at least one array of electrodes which is itself coated with an array of barrier ribs made of a mineral material, the porosity of which is greater than 25%, comprising a porous base underlayer which is inserted between the array of electrodes and the array of barrier ribs 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.

Plate for a plasma panel with reinforced porous barriers

Process comprising the following steps: a) deposition of a green layer based on 0.1% of an organic binder, on a mineral filler and on 0.1% to 13% of a mineral binder; b) formation of the barriers by spraying an abrasive material onto a mask applied against this layer, and then removal of the mask; c) deposition of a phosphor-based green layer; d) baking of the two layers, preferably simultaneously. By virtue of the limited amount of organic binder, the abrasion rate is high; if this content is at least 2%, deterioration of the green barriers is avoided.

Process for manufacturing barriers for a plasma display panel

A plasma panel including two plates having a sealed space between them is disclosed. The sealed space is filled with discharge gas and is divided into discharge cells that are bounded between these plates by barrier ribs forming an array. The barrier rib portion that separates any two adjacent cells of the same column includes a cavity that is made in the thickness of that rib, and a notch that brings these two cells into communication with each other through the cavity. Such an arrangement makes it easier to apply the phosphors on the walls of the cells, while at the same time eliminating any risk of optical crosstalk.
