Abstract:
The present disclosure describes nano-structured 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.
