Title
(EN) ORGANIC ELECTROLUMINESCENT DEVICE
(FR) DISPOSITIF ELECTROLUMINESCENT ORGANIQUE
Abstract
(EN)
An organic electroluminescent device comprises a substrate that supports a first electrode, a second electrode, and a light emitting structure that is disposed between the first and second electrodes. A protective structure comprising a layer of boron oxide and an inorganic barrier layer cooperates with the substrate to encapsulate the first electrode, the second electrode, and the light-emitting structure.
(FR)
Le dispositif électroluminescent organique selon l’invention comprend un substrat qui supporte une première électrode, une deuxième électrode et une structure électroluminescente qui est disposée entre la première électrode et la deuxième électrode. Une structure de protection comprenant une couche d’oxyde de bore et une couche de barrière inorganique coopère avec le substrat pour encapsuler la première et la seconde électrode, ainsi que la structure électroluminescente.
