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 (100) with laminated sub-micron extractors (110a-c) include: (a) an extractor (110a) on a transparent substrate (112a) for light outcoupling on both sides of the transparent device (120); or (b) an extractor (110b) on a reflective film (112b) for providing light outcoupling off the bottom side of the bottom-emitting (BE) AMOLED (120); or (c) an extractor (110c) on a light absorbing film (112c) for providing outcoupling off the bottom side of the BE AMOLED (120) combined with improved ambient contrast.
