Abstract:
Presently described is a method for coupling an optical film to a substrate, laminated optical constructions comprising an optical film and an optical coupling layer disposed on a surface layer of the optical film, and coating compositions useful for optical an optical coupling layer. The coating compositions comprise at least 40 wt.-% inorganic nanoparticles having a refractive index of at least 1.85 and a polymeric silane surface treatment.
Abstract:
The present disclosure provides a light emitting device, an active matrix organic light emitting diode (AMOLED) device that includes the light emitting device, and an image display device that includes the light emitting device. In particular, the light emitting device includes a microcavity organic light emitting diode (OLED) (120), a light extraction film (110), and a high-index capping layer (122) disposed between the microcavity OLED and the light extraction film.
Abstract:
The present disclosure provides novel light emitting devices including AMOLED displays, based on transparent OLED architecture, where a laminated nanostructurcd 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 (llOa-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.
