A barrier adhesive composition comprising a resin system and organically modified nanoclay. The resin system comprises (a) a first polyisobutylene resin having a viscosity average molecular weight of about 300,000 to about 500,000 g/mol, (b) a second polyisobutylene resin having a viscosity average molecular of about 700,000 to about 900,000 g/mol and (c) tackifier.

Nanoclay filled barrier adhesive compositions

Barrier assemblies including ultrathin barrier laminates and methods of making the barrier assemblies are provided. A barrier assembly includes a thermoplastic polymer skin layer having opposite first and second major surfaces, and a barrier stack coated on the first major surface of the thermoplastic polymer skin layer to form an integral protective layer having a thickness no greater than about 0.5 mil (about 12.7 microns). The removable carrier film has a major surface releasably attached to the second major surface of the thermoplastic polymer skin layer. In some cases, the removal of the carrier film results in ultrathin barrier laminates.

Ultrathin barrier laminates and devices

A barrier film construction comprises an ultra-barrier film and a barrier adhesive. The adhesive layer comprises a barrier adhesive composition comprising a resin system and organically modified nanoclay; wherein the resin system comprises a first polyisobutylene resin having a viscosity average molecular weight of about 100,000 to about 1,200,000 g/mol and tackifier.

Barrier film constructions

The present disclosure relates to forming a bond with a high peel resistance between a bonding layer and an adjacent barrier layer. Such articles are particularly useful in the preparation of a device, in particular a luminescent device, and a method is described for assembly of the luminescent device. The luminescent device includes an encapsulation system using flexible transparent barrier film and an ultraviolet (UV) radiation curable (meth)acrylate matrix. The moisture sensitive luminescent material can be, for example, a quantum dot material disposed in a film, or a film construction that includes an OLED structure.

Adhesive barrier film construction

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.

Conducting film or electrode with improved optical and electrical performance for display and lighting devices and solar cells

An encapsulating film system comprises (a) a flexible barrier film, (b) an adhesive on at least a portion of the flexible barrier film, and (c) a desiccant on at least a portion of the flexible barrier film or the adhesive.

Flexible encapsulating film systems

Encapsulated organic electronic devices including organic light emitting diodes are made using an adhesive component as a mask while the device is being constructed. An adhesive-coated liner can be applied to the device substrate and openings created therein by removing portions of the liner and adhesive, or a patterned adhesive layer having openings therein can be formed on the device substrate, followed by deposition of the device layers and application of a sealing layer.

Encapsulated organic electronic devices and method for making same

A multifunctional optical film for enhancing light extraction includes a flexible substrate, a structured layer, and a backfill 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 lighting device such as solid state lighting devices or backlight units. 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.

Methods for providing light extraction films on organic light emitting diode devices

A process for fabricating an amorphous diamond-like film layer for protection of a moisture or oxygen sensitive electronic device is described. The process includes forming a plasma from silicone oil, depositing an amorphous diamond-like film layer from the plasma, and combining the amorphous diamond-like film layer with a moisture or oxygen sensitive electronic device to form a protected electronic device. Articles including the amorphous diamond-like film layer on an organic electronic device are also disclosed.

Moisture barrier coatings for organic light emitting diode devices

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.

Adhesive encapsulating composition and electronic devices made therewith

Light extraction film for organic light emitting diode display and lighting devices

Patterning an organic light emitting diode (OLED) after it has been encapsulated by permanently changing the light emissivity of the diodes. The OLED includes an intervening layer between a source of laser treatment and a light emitting layer. Depending on the composition of the light emitting layer, the laser treatment will enhance or diminish brightness.

Laser patterning of encapsulated organic light emitting diodes

A flexible barrier assembly having a flexible visible light-transmissive substrate having a Tg greater than or equal to that of heat-stabilized polyethylene terephthalate ('HSPET') overcoated with a first polymer layer having a Tg greater than or equal to that of HSPET and further overcoated with at least two visible light-transmissive inorganic barrier layers separated by at least one second polymer layer having a Tg greater than or equal to that of HSPET can be used to mount, cover, encapsulate or form moisture- and oxygen-sensitive articles such as organic light emitting devices and light valves.

Flexible high-temperature ultrabarrier

An electroluminescent device, and a method of making an electroluminescent device that includes one or more color conversion elements is disclosed. In one embodiment, the method includes forming an electroluminescent element on a substrate, where the electroluminescent element is capable of emitting light in a narrow band. The method further includes selectively thermally transferring a plurality of color conversion elements to the electroluminescent element. In another embodiment, the method includes forming an electroluminescent element on a substrate, where the electroluminescent element is capable of emitting UV light. The method further includes selectively thermally transferring a plurality of color conversion elements to the electroluminescent element.
