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:
Variable index light extraction layers (100) that contain a plurality of microreplicated posts (120) are described. The variable index light extraction layers contain a plurality of microreplicated posts (120), a first region including a first lower-index substance (130) and a second region including a second higher-index substance (140). Optical films can use the variable index light extraction layers (100) in front lit or back lit display devices.
Abstract:
An electronically switchable privacy films suitable for use in display devices are described. The electronically switchable privacy film comprises a pair of mutually opposing transparent electrodes; an optically transparent microstructured layer disposed between the transparent electrodes, the microstructured layer comprising a plurality of microstructured ribs extending across a surface thereof such that the microstructured ribs form an alternating series of ribs and channels; and electronically switchable material disposed in the channels, the electronically switchable material being capable of modulation between high and low absorption states upon application of an electric field across the transparent electrodes.
Abstract:
An article including an airfoil or hydrofoil is disclosed. On at least a portion of a surface of the airfoil or hydrofoil there is a seamless film having a series of substantially parallel peaks separated from each other by a series of substantially parallel valleys on a patterned first surface of the film, wherein the seamless film has a long dimension that is at least two meters long substantially aligned with the span of the airfoil or hydrofoil, and wherein an angle between the parallel peaks and valleys to the long dimension of the seamless film is at least five degrees. Methods of making the article are also disclosed.
Abstract:
The present invention includes ultraviolet curable compositions preferably containing discrete, crystalline zirconia nanoparticles with reactive, or copolymerizable, surface modification, in a polymerizable monomer/oligomer resin mixture. It is believed that copolymerizable surface modification provides a functional group that enables the functionalized particle to co-polmerize with the reactive monomers, oligomers, and crosslinkers in the formulation. Relative to surface modifation of the nanoparticles, acrylate functionality is preferred over methacrylate functionality. On the other hand, methacrylate functionality is preferred over non-reactive, or nonpolymerizable, functionality. As the nanocomposite cures, the resultant network is heavily crosslinked by selection of raw materials with substantial acrylate functionality.
