A conducting film or device multilayer electrode includes a substrate and two transparent or semitransparent conductive layers separated by a transparent or semitransparent intervening layer. The intervening layer includes electrically conductive pathways between the first and second conductive layers to help reduce interfacial reflections occurring between particular layers in devices incorporating the conducting film or electrode.

A system and a method for providing a film having a matte finish is described. A coatable material is applied to a substrate. The viscosity of the coatable material is changed and a face-side roller having patterned features thereon contacts the coatable material to impart a matte finish thereon; and hardening the coatable material.

System and method for making a film having a matte finish

Optical films for enhancing light extraction from self-emissive light sources such as bottom-emitting or top-emitting OLEDs are disclosed. The extraction films typically include a flexible carrier film, and a first and second layer carried by the carrier film. The first or second layer has a nanovoided morphology and includes a polymer binder, and may also have a refractive index less than 1.35 or 1.3. An embedded structured surface of light extraction elements is formed between the first and second layers. The light extraction elements may be primarily diffractive elements adapted to be disposed within an evanescent zone of the OLED, or they may be primarily refractive elements adapted to be disposed outside the evanescent zone. The extraction film may also include a third layer, and a second embedded structured surface may be formed between the third layer and the first layer.

Light extraction films for organic light emitting devices (OLEDs)

A light extraction film having internal nanostructures and external microstructures for organic light emitting diode (OLED) devices. The light extraction film includes a flexible substantially transparent film, a low index nanostructured layer applied to the film, and a high index planarizing backfill layer applied over the nanostructured layer. External optical microstructures are applied to the flexible substantially transparent film on a side opposite the nanostructured layer to enhance light extraction from the OLED devices while providing for a more uniform luminance distribution.
