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.
