| 20080274352 | OPTICAL FILM COMPRISING ANTISTATIC PRIMER AND ANTISTATIC COMPOSITIONS - Optical films are described that comprise an antistatic primer disposed on the substrate and a high refractive index layer disposed on the primer. The primer comprises a sulfopolymer and at least one antistatic agent. The high refractive index layer comprises surface modified inorganic nanoparticles dispersed in a crosslinked organic material. The antistatic agent is preferably selected from conductive inorganic particles, conductive polymer, and mixtures thereof. Also describes are antistatic compositions and surface treated conductive inorganic oxide particles. | 11-06-2008 |
| 20100003501 | FLEXIBLE HIGH REFRACTIVE INDEX HARDCOAT - Antireflective films comprising a flexible high refractive index layer that comprises at least 60 wt-% of inorganic nanoparticles, the nanoparticles having a refractive index of at least 1.60, dispersed in a crosslinked organic material. Also described are surface treated nanoparticles. | 01-07-2010 |
| 20100028564 | ANTISTATIC OPTICAL CONSTRUCTIONS HAVING OPTICALLY-TRANSMISSIVE ADHESIVES - Antistatic optical constructions have optical films that include antistatic layers and optically-transmissive adhesives. A liquid crystal display assembly including the antistatic construction is also disclosed. | 02-04-2010 |
| 20100110551 | LIGHT EXTRACTION FILM WITH HIGH INDEX BACKFILL LAYER AND PASSIVATION LAYER - A multifunctional optical film for enhancing light extraction includes a flexible substrate, a structured layer, a high index backfill layer, and an optional passivation 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 display device. 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. | 05-06-2010 |
| 20100171929 | DRY ERASABLE PROJECTION ARTICLE AND SYSTEM - A communication article and system comprising a writing member having a dry erasable front surface and a projection member is disclosed. The projection member includes an asymmetric optical diffuser that scatters light in a first direction with a first viewing angle A | 07-08-2010 |
| 20100265584 | RETROREFLECTING OPTICAL CONSTRUCTION - Retroreflecting optical constructions are disclosed. A disclosed retroreflecting optical construction includes a retroreflecting layer that has a retroreflecting structured major surface, and an optical film that is disposed on the retroreflecting structured major surface of the retroreflecting layer. The optical film has an optical haze that is not less than about 30%. Substantial portions of each two neighboring major surfaces in the retroreflecting optical construction are in physical contact with each other. | 10-21-2010 |
| 20100310875 | HARDCOATS COMPRISING PERFLUOROPOLYETHER POLYMERS WITH POLY(ALKYLENE OXIDE) REPEAT UNITS - Presently described are articles, such as optical displays and protective films, comprising a (e.g. light transmissive) substrate having a surface layer comprising the reaction product of a mixture comprising a non-fluorinated binder precursor (e.g. of a hardcoat composition) and at least one polymerizable perfluoropolyether polymer. The resulting cured surface layer can advantageously exhibit low lint attraction in combination with low surface energy. Also described are one-step and two-step methods of synthesizing perfluoropolyether polymers having polymerizable ethylenically unsaturated groups. | 12-09-2010 |
| 20110126734 | FUNCTIONALIZED ZIRCONIA NANOPARTICLES AND HIGH INDEX FILMS MADE THEREFROM - The present disclosure relates to surface-modified zirconia nanoparticles, methods for making and using the same, and high index of refraction films made therefrom. The provided zirconia nanoparticles are surface modified with ligands that include N-hydroxyurea functionalities. The provided ligands also can contain compatibilizing groups that allow the provided surface-modified zirconia nanoparticles to be incorporated into an organic matrix. High index of refraction films can be made using these organic matrices. | 06-02-2011 |
