摘要:
Organic electroluminescent device can be formed with multiple layers including an electrode, an emission layer, and a buffer layer. The emission layer includes a light emitting material. The buffer layer is disposed between and in electrical communication with the electrode and the emission layer and includes a triarylamine hole transport material and an electron acceptor material. The buffer layer optionally includes one or more of a) a polymeric binder, b) a color converting material, and c) light scattering particles. The buffer layer can also be formed using a polymeric hole transport material having a plurality of triarylamine moieties.

摘要:
The present invention provides an active primer that includes an electronically active material dispersed in a binder. The active primer can be disposed between a thermal transfer donor sheet and a receptor to assist selective thermal transfer of a material from the donor sheet to the receptor to form at least a portion of an electronic device on the receptor. The binder of the active primer can be selected to improve adhesion of the transferred material to the receptor, or to enhance other transfer properties. The electronically active material of the active primer can be selected to maintain a desired level of functionality in the electronic device being patterned on the receptor.
摘要:
An organic electroluminescent device comprises a substrate that supports a first electrode, a second electrode, and a light emitting structure that is disposed between the first and second electrodes. A protective structure comprising a layer of boron oxide and an inorganic barrier layer cooperates with the substrate to encapsulate the first electrode, the second electrode, and the light-emitting structure.

A protected polymeric film comprises a polymeric film substrate having a first major surface and a second major surface opposite the first major surface, and a protective structure provided on at least the first major surface of the substrate, wherein the protective structure comprises a layer of boron oxide and an inorganic barrier layer. A protective structure may also be provided on the second major surface of the substrate. Organic electronic components may be formed on or attached to the protected polymeric films.

The present invention provides a selectively thermally transferable blend capable of forming the emissive layer of an organic electroluminescent device. The blend includes a light emitting polymer and an additive selected to promote selective thermal transfer of the blend from a donor element to a proximately located receptor substrate.
摘要:
A display system includes a reflective display panel and a light source tailored to enhance the color gamut of the system. The panel, which may be a Cholesteric liquid crystal display panel, includes an array of reflective pixels, each pixel comprising a first, second, and third subpixel of different first, second, and third colors. The light source illuminates a front of the display panel with source light to enable observers to view images formed by the panel. The light source includes a lamp and an enhancing element. The lamp, which may be a metal halide lamp, emits lamp light that includes the first, second, and third colors. The enhancing element may be an optical filter, a supplemental LED light source or other light source, or both. The enhancing element enhances the system color gamut, for example, by increasing the color gamut area relative to illumination with the lamp alone.
