Abstract:
A light management unit is described for attachment to a display module, especially suited for an LCD TV or LCD monitor. The light management unit includes a directionally recycling layer including a structured side and a planar side where the structured side includes prism structures. The light management unit also includes a reflective polarizer positioned on the planar side of the directionally recycling layer. The light management unit also includes a diffusion structure incorporated into either the directionally recycling layer or between the directional recycling layer and the reflective polarizer. The diffusion structure causes a level of diffusion that is sufficient to prevent the appearance of colored bands when a viewer positioned along a line of sight that is perpendicular to the direction of the prism structures views the light management unit, illuminated from below, at an oblique angle from a vertical axis.
Abstract:
Plastic articles can be coated with polymerizable compositions containing a vinyl-functional crosslinkable film former, a large amount of benzotriazole and a copolymerizable monomer that solubilizes the benzotriazole. The cured compositions help protect the article from UV exposure and other weathering effects.
Abstract:
A durable optical film or element includes a polymerized structure having a microstructured surface and a plurality of surface modified colloidal nanoparticles of silica, zirconia, or mixtures thereof. Display devices including the durable microstructured film are also described.
Abstract:
Presently described are microstructured articles such as a brightness enhancing film or optical turning film. The microstructured articles comprise a brightness enhancing polymerized structure comprising the reaction product of a composition comprising an organic component having at least one oligomeric urethane (meth)acrylate and surface modified silica nanoparticles.
Abstract:
An optical body including an optical film, a first layer on a first major surface of the optical film, and a second layer on a second major surface of the optical film, wherein at least one of the first and second layers may include an adhesion-promoting layer that comprises a polycarbonate/polyester blend resin or a styrene copolymer. The present disclosure is also directed to an optical body wherein at least one of the first and second layers may include an imprint-resistant layer that comprises a polymer selected from the group consisting of crystalline polyesters, copolyesters, olefin homopolymers and olefin copolymers.
Abstract:
Presently described are microstructured articles such as a brightness enhancing film or optical turning film comprising a polymerized structure comprising the reaction product of a polymerizable composition comprising an (A) organic component comprising (i) at least one monofunctional acrylic monomer selected from t-alkyl (meth)acrylates, N-substituted or N,N-disubstituted (meth)acrylamides, and C1-8 primary or secondary alkyl (meth)acrylate; (ii) at least one multifunctional (meth)acrylate or (meth)acrylamide monomer; (iii) optionally, at least one oligomeric (meth)acrylate; and (iv) at least one photoinitiator; and (B) at least 10 wt-% inorganic nanoparticles.
Abstract:
A norbomene-based cyclic olefin layer with a curable layer disposed thereon is described. The curable layer may additionally be imparted with a texture. The norbomene-based cyclic olefin films with curable layers can be incorporated into optical bodies which include an optical film, such as an oriented multilayer optical film. In addition, the invention includes a method of coating a curable layer onto a norbomene-based polymer layer or film without requiring a primer layer. Methods of making the norbomene-based cyclic olefin layer containing films are also disclosed.
