Abstract: The present disclosure provides novel light emitting devices including AMOLED displays, based on transparent OLED architecture, where a laminated nanostructured light extraction film can produce axial and integrated optical gains as well as improved angular luminance and color. Generally, the transparent AMOLED displays with laminated sub-micron extractors include: (a) an extractor on a transparent substrate for light outcoupling on both sides of the transparent device; or (b) an extractor on a reflective film for providing light outcoupling off the bottom side of the bottom-emitting (BE) AMOLED; or (c) an extractor on a light absorbing film for providing outcoupling off the bottom side of the BE AMOLED combined with improved ambient contrast.
