Patent

CA 2437472

The invention is an optoelectronic device comprising a transparent polymeric substrate (12) bearing on one surface thereof a transparent polymerized organosilicon protective layer (13), a first electrode (21) over the polymerized protective layer (13), an optoelectrically active film (20) comprising an electroactive material, said film having a first side, which is in contact with the transparent electrode (21) and a second side in contact with a second electrode (25), wherein said first electrode (21) is characterized in that it allows light to pass to or from the optoelectrically active film (20). Preferably, the device further comprises additional protective packaging (31-33) over the second electrode.

L'invention concerne un composant optoélectronique comprenant un substrat polymère transparent dont une surface porte une couche protectrice transparente polymérisée d'organosilicium, une première électrode au-dessus de cette couche protectrice polymérisée, une couche mince optoélectrique comprenant un matériau électroactif, ladite couche mince possédant un premier côté en contact avec l'électrode transparente et un deuxième côté en contact avec une deuxième électrode, ladite première électrode permettant, de façon caractéristique, à la lumière de la traverser en direction de la couche mince optoélectrique ou depuis ladite couche. Ce composant comprend, de plus, et de préférence, un boîtier de protection supplémentaire au-dessus de la deuxième électrode.
