  • Patent number: 10957878
    Abstract: Lamination transfer films and methods for transferring a structured layer to a receptor substrate. The transfer films include a carrier substrate having a releasable surface, a sacrificial template layer applied to the releasable surface of the carrier substrate and having a non-planar structured surface, and a thermally stable backfill layer applied to the non-planar structured surface of the sacrificial template layer. The sacrificial template layer is capable of being removed from the backfill layer, such as via pyrolysis, while leaving the structured surface of the backfill layer substantially intact.

  • Patent number: 10629827
    Abstract: Organic light emitting devices are described wherein the emissive layer comprises a host material containing an emissive molecule, which molecule is adapted to luminesce when a voltage is applied across the heterostructure, and the emissive molecule is selected from the group of phosphorescent organometallic complexes, including cyclometallated platinum, iridium and osmium complexes. The organic light emitting devices optionally contain an exciton blocking layer. Furthermore, improved electroluminescent efficiency in organic light emitting devices is obtained with an emitter layer comprising organometallic complexes of transition metals of formula L2MX, wherein L and X are distinct bidentate ligands. Compounds of this formula can be synthesized more facilely than in previous approaches and synthetic options allow insertion of fluorescent molecules into a phosphorescent complex, ligands to fine tune the color of emission, and ligands to trap carriers.

  • Publication number: 20170301888
    Abstract: 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.

  • Patent number: 9773847
    Abstract: The disclosure relates to emissive displays and, in particular, to emissive displays that include a top surface (111) that has a diffusely reflective inactive surface (116) adjacent a diffusely reflective emissive surface (114). The emissive display further includes a polarization selective antireflection film component (120) that includes a linear absorbing polarizer (126), a reflective polarizer (124), and a quarter-wave retarder (122), and is positioned separated from the top surface. The disclosure also relates to issues arising from these antireflection film components, such as brightness efficiency loss and image degradation such as pixel blur. The enhanced antireflection stack performs well in commercial OLED displays, with a 20% or greater brightness gain, a 30% or greater ambient light reflectance gain and no visually apparent image degradation.
