    Abstract: Methods of forming laminating adhesive articles include providing a multi-layer article, and a tool with a structured surface. The multi-layer articles include a substrate, an adhesive layer, and a liner. The multi-layer article is placed between the structured surface of the tool and a support surface that is hard and the tool is embossed against the liner by applying pressure or pressure/heat. The embossing causes the tool structures to distort the liner and the adhesive layer, and causes permanent topological changes in a portion of the adhesive layer, but does not distort the substrate. The distortion in the liner is retained upon release of the applied pressure. The portions of topologically changed adhesive can form convex structures that are permanent. Upon removal of the liner from the adhesive layer, the concave structures on the adhesive layer are unstable, but the convex structures are stable.

    Abstract: The present disclosure describes nanostructured light extraction color filter laminates, and articles and methods of using nanostructured light extraction color filter laminates for the fabrication of an OLED including a nanostructure, using lamination techniques. Nanostructured OLED devices can exhibit enhanced light extraction efficiency. The methods involve transfer and/or replication of a film, layer, or coating in order to form a nanostructured surface that is in optical contact with the emitting surface of an OLED in, for example, a top emitting or a bottom emitting active matrix OLED (TE-AMOLED or BE-AMOLED) device. The articles having enhanced light extraction efficiency can be of particular use in color-by-white (CBW) OLED displays, which use white-light spectrum OLEDs with a color filter array.
