摘要： A light extraction film laminated to a glass substrate 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. A glass substrate is laminated to the flexible substantially transparent film on a side opposite the nanostructured layer and including an ultra-low index region between the film and the glass substrate. The ultra-low index region is used to reduce optical losses occurring with the glass substrate.

摘要： A multifunctional optical film for enhancing light extraction includes a flexible substrate, a structured layer, a high index backfill layer, and an optional passivation layer. The structured layer effectively uses microreplicated diffractive or scattering nanostructures located near enough to the light generation region to enable extraction of an evanescent wave from an organic light emitting diode (OLED) device. The backfill layer has a material having an index of refraction different from the index of refraction of the structured layer. The backfill layer also provides a planarizing layer over the structured layer in order to conform the light extraction film to a layer of an OLED display device. The film may have additional layers added to or incorporated within it to an emissive surface in order to effect additional functionalities beyond improvement of light extraction efficiency.
