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.

Adhesive encapsulating compositions for use in electronic devices such as organic electroluminescent devices, touch screens, photovoltaic devices, and thin film transistors are disclosed herein. The adhesive encapsulating compositions include pressure sensitive adhesives comprising one or more polyisobutylene resins, in combination with optional multifunctional (meth)acrylate monomers and/or optional tackifiers.
