An OLED device which is capable of utilizing light transmitted from the sides of the OLED as well as the surface of the OLED is provided. The OLED device comprises an OLED having a substrate surface and sides for emission of photons therethrough and at least one adjacent light-folding means, wherein said light-folding means collects and redirects photons emitted from the sides of the OLED into coincident paths of light which are substantially parallel to said photons emitted from said substrate surface.

Un dispositif d'OLED qui est capable d'utiliser la lumière transmise des côtés de l'OLED comme la surface de l'OLED est fourni. Le dispositif d'OLED comporte un OLED ayant une surface et des côtés de substrat pour l'émission des photons par là et au moins les moyens un lumière-se pliants adjacents, où ledit moyen lumière-se pliant rassemble et réoriente des photons émis des côtés de l'OLED dans les chemins coïncidents de la lumière qui sont essentiellement parallèles à lesdits photons émis de ladite surface de substrat.
