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.
