An emissive display comprising an OLED, a first birefringent reflective polarizer, a second birefringent reflective polarizer optically between the OLED and the first birefringent reflective polarizer, a first linear absorbing polarizer having a contrast ratio of less than 100:1 optically between the first birefringent reflective polarizer and the second birefringent reflective polarizer, a second linear absorbing polarizer having a contrast ratio of less than 100:1, where the first birefringent reflective polarizer is optically between the second linear absorbing polarizer and the first linear absorbing polarizer, and a structured optical film optically between the OLED and the second birefringent reflective polarizer.

Emissive display with hybrid polarizer

The present disclosure provides novel light emitting devices including AMOLED displays, based on transparent OLED architecture, where a laminated nanostructured light extraction film can produce axial and integrated optical gains as well as improved angular luminance and color. Generally, the transparent AMOLED displays () with laminated sub-micron extractors (-) include: (a) an extractor () on a transparent substrate () for light outcoupling on both sides of the transparent device (); or (b) an extractor () on a reflective film () for providing light outcoupling off the bottom side of the bottom-emitting (BE) AMOLED (); or (c) an extractor () on a light absorbing film () for providing outcoupling off the bottom side of the BE AMOLED () combined with improved ambient contrast.

Transparent OLED light extraction

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

The present disclosure relates to illumination or lighting assemblies and systems that provide illumination using LEDs. In one aspect, the present disclosure provides a lighting assembly, comprising: multiple light emitting diodes that emit light; an optical system that directs the light emitted by the light emitting diodes, the optical system positioned adjacent to light emitting diodes; and a cooling fin including a two-phase cooling system, the cooling fin positioned adjacent to the light emitting diodes such that the two-phase cooling system removes heat from the light emitting diodes. In another aspect, the present disclosure provides a lighting system including multiple lighting assemblies. The lighting assemblies and systems of the present disclosure can be used in, for example, a street light, a backlight (including, for example, a sun-coupled backlight), a wall wash light, a billboard light, a parking ramp light, a high bay light, a parking lot light, a signage lit sign (also referred to as an electric sign), static signage (including, for example, sun-coupled static signage), illuminated signage, and other lighting applications.

Street light

A method of forming a metallic material on a receptor that includes the steps of: placing a donor element proximate a receptor, wherein the donor element includes a donor substrate and a thermal transfer layer, wherein the thermal transfer layer includes a catalytic material, and wherein the thermal transfer layer of the donor element is placed proximate the surface of the receptor; thermally transferring at least a portion of the thermal transfer layer from the donor element to the receptor; and electrolessly depositing a metallic material on the receptor by growth of the metallic material on the catalytic material.

Method of patterning a substrate

Radiation curable thermal transfer elements including a substrate and a light-to-heat conversion layer overlaying the substrate, and processes to make the thermal transfer elements. The light-to-heat conversion layer is derived from a radiation curable material capable of being cured by exposure to radiation at a curing wavelength and an imaging radiation absorber material not substantially increasing radiation absorbance at the curing wavelength. The radiation curable transfer elements can be used in processes for making organic microelectronic devices.

Radiation curable thermal transfer elements

An optical imaging system is disclosed for selective thermal transfer of a material from a donor film to a substrate. The imaging system includes a light source assembly that is configured to emit a patterned light beam. The patterned light beam includes a plurality of discrete output light segments where the segments at most partially overlap. The imaging system further includes a light relay assembly that receives and projects the plurality of discrete output light segments onto a transfer plane so as to form a projected light segment by a substantial superposition of the plurality of discrete output light segments. When a donor film that includes a transferable material is placed proximate a substrate that lies in the transfer plane, the projected light segment is capable of inducing a transfer of the transferable material onto the substrate.

Imaging system for thermal transfer

A thermal transfer donor element is provided which comprises a support, a light-to-heat conversion layer, an interlayer, and a thermal transfer layer. When the above donor element is brought into contact with a receptor and imagewise irradiated, an image is obtained which is free from contamination by the light-to-heat conversion layer. The construction and process of this invention is useful in making colored images including applications such as color proofs and color filter elements.

Laser addressable thermal transfer imaging element with an interlayer

The present invention provides a process for selectively thermally transferring insulators onto organic electroluminescent stacks or layers to electronically isolate adjacent devices upon deposition of electrode material. This can allow the formation of top electrodes for a plurality of organic electroluminescent devices on a substrate via one deposition step to form a single common top electrode or a plurality of electrodes patterned by shadowing due to the presence of the insulators.
