Definitions
- the role of the dielectric layer 38 is to protect the electroluminescent material or materials used, during the various stages of production of the matrix screen. For this reason, its thickness should be greater than that of the electroluminescent layer.
- this layer 38 is made of a material different from that constituting the dielectric layer 36 in order to facilitate the stopping of the subsequent etchings of the layer 38.
- the latter can in particular be made of Ti0 2 , Si0 2 , Al 2 O 3 , SisN 4 , Ta 2 0s, Y 2 0 3 .
- the dielectric layer 38 can be produced in Y 2 0 3 .
- This dielectric layer 38 can for example be deposited by vacuum evaporation, sputtering, or any other technique of depositing thin layers, and have a thickness of 1200 nm.
- the next step in the process consists, as shown in FIG. 7, in covering the entire body of the structure (except at the ends of the electrodes) with a layer 46 of a first electroluminescent material.
- This layer 46 can for example be made of ZnS doped with manganese, ZnS doped TbF 3 or SrS doped CeF 3 .
- this layer 46 is made of ZnS with a manganese doping of 3 to 3.5% by mole; it has a luminance of 55 cd / m 2.
- This electroluminescent layer 46 having for example a thickness of 800 nm can be deposited by vacuum evaporation.
- openings 54 are located opposite a second conductive strip for example 32b of each electrode of the first family and opposite a second conductive strip of each electrode of the second family, in the case where these electrodes are formed of two conductive strips.
- the dimensions of these openings are defined by the width of the conductive strips of the electrodes of the first and second families.
