Title
(EN) ELECTROLUMINESCENT DEVICE AND A WAY TO FABRICATE IT
(FR) DISPOSITIF ELECTROLUMINESCENT ET SON PROCEDE DE FABRICATION
Abstract
(EN)
An electroluminescent device has a preferably transparent or translucent material constituted substrate, a first electrode layer (11) applied on this, a light emitting layer (12, 13) applied on this and the substrate (10) and displaying a light emitting ability and constituted by a conjugated polymer or a polymer mixture and a second electrode layer (14) applied on top of the light emitting layer (12, 13), the electroluminescent device being provided with connections (15, 16) to the two electrode layers. According to the invention a light emitting layer (12, 13) includes a separately fabricated, integral, light emitting layer (13). Preferably this layer (13) is pre-treated, in particular tensioned in one direction in order to orient the major part of the polymeric chains in the polymeric material in this direction. At the preferable embodiment the light emitting layer is constituted by several partlayers (12, 13). At the fabrication of such an electroluminescent device is used a manner, in which at least a part (13) of the light emitting layer (12, 13) is applied by transferring it from a carrier or a support, on which this layer (13) first has been made, the transfer from the carrier for the lamination with the underlying of the electroluminescent device preferably is executed first since this part (13) of the light emitting layer (12, 13) has been subjected to a pretreatment, in particular a strectching in a direction for orientation of the polymer chains in the polymer material in this direction.

Dispositif électroluminescent comportant un substrat constitué d'un matériau transparent ou translucide, une première couche d'électrode (11) appliquée sur le substrat, une couche photoémettrice (12, 13) appliquée sur la précédente et sur le substrat (10) capable d'émettre de la lumière et constituée d'un polymère conjugué ou d'un mélange de polymères, et une deuxième couche d'électrode (14) appliquée sur la couche photoémettrice (12, 13), et pourvu de connexions (15, 16) pour les deux couches électrodes. Selon l'invention, une couche photoémettrice (12, 13) comporte une couche émettrice solidaire (13) fabriquée séparément et préretraitée notamment par étirage dans une direction en vue d'orienter la majeure partie des chaînes polymères du matériau polymère dans cette direction. Dans le mode de réalisation préféré, la couche photoémettrice est composée de plusieurs couches partielles (12, 13). La fabrication du dispositif électroluminescent recourt à une technique selon laquelle au moins une partie (13) de la couche photoémettrice (12, 13) s'applique par transfert à partir d'un support sur lequel cette couche (13) a tout d'abord été constituée, ledit transfert depuis le support en vue d'une stratification avec les parties sous-jacentes du dispositif électroluminescent étant exécuté en premier puisque cette partie (13) de la couche photoémettrice (12, 13) a été soumise à un prétraitement, en particulier un étirage dans une direction permettant l'orientation des chaînes de polymères dans le matériau polymère, dans ladite direction.
