    Abstract: A light control film includes a two-dimensional array of projections arranged across the light control film. A square of a magnitude of a Fourier transform frequency spectrum of the projections includes a plurality of distinct peaks separated by one or more valleys. The peaks and the one or more valleys have respective averages Pavg and Vavg, Pavg/Vavg≥5, such that when light from a substantially Lambertian light source is incident on the light control film, the light control film transmits the incident light with the transmitted light propagating along a transmission axis and having an intensity profile having a full width at half maximum of less than about 120 degrees in each cross-section of the intensity profile that comprises the transmission axis.

    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.
