Abstract
La présente invention concerne un procédé permettant de former un dispositif d'affichage électroluminescent organique à matrice active. Ledit procédé consiste à former un ensemble de plaque électroluminescente organique, à former un ensemble de plaque de matrice active, et à sceller hermétiquement l'ensemble de plaque électroluminescente organique sur l'ensemble de matrice active. L'ensemble de plaque de matrice active peut comprendre un substrat équipé de circuits de commande et au moins une plage de pixel. Cette plage de pixel peut être réalisée dans un matériau injecteur d'électrons. Le matériau injecteur d'électrons peut être choisi dans le groupe composé de Mg+Al, Al+Li, LiF/Al et CsC. Le procédé peut en outre inclure une étape au cours de laquelle on nettoie la plage de pixel avant de sceller hermétiquement l'ensemble de plaque électroluminescente organique sur l'ensemble de plaque de matrice active. Le nettoyage peut comprendre une étape au cours de laquelle on nettoie au moins une plage de pixel à l'aide d'un faisceau ionique.
