A conducting film or device electrode includes a substrate and two transparent or semitransparent conductive layers separated by a transparent or semitransparent intervening layer. The intervening layer includes electrically conductive pathways between the first and second conductive layers to help reduce interfacial reflections occurring between particular layers in devices incorporating the conducting film or electrode.

Ultraviolet-C (UV-C) radiation shielding films including a substrate made of a fluoropolymer, a multilayer optical film disposed on a major surface of the substrate, and a heat-sealable encapsulant layer disposed on a major surface of the multilayer optical film opposite the substrate. The multilayer optical film is made of at least a multiplicity of alternating first and second optical layers collectively reflecting at an incident light angle of at least one of 0, 30, 45, 60, or 75, at least 30 percent of incident ultraviolet light over at least a 30-nanometer wavelength reflection bandwidth in a wavelength range from at least 100 nanometers to 280 nanometers. The ultraviolet light shielding film may be applied to a major surface of a photovoltaic device, such as a component of a satellite or an unmanned aerial vehicle. Methods of making the UV-C radiation-protective films also are disclosed.

A stretchable reflective color-shifting film comprises a stretchable transparent polymer layer; a semi-transmissive metal layer; a transparent spacer layer; a reflective metal layer; an adhesive layer; and a stretchable base film layer. When the film body is stretched by 25%, the peak total reflectance stretched is at 80% of the peak total reflectance when the film body is unstretched according to the Total Reflectivity Test.

A patterned optical retarder including non-overlapping first () and second () regions with respective first and second major surfaces having different RMS surface roughnesses. For substantially normally incident light over a wavelength range from about 400 nm to about 1000 nm, the optical retarder has different retardances in the respective first and second regions.

In certain embodiments, the present disclosure relates to low emissivity films and articles comprising them. Other embodiments are directed to methods of reducing emissivity in an article comprising the use of low emissivity films. In some embodiments, the low emissivity films comprise a metal layer and a pair of layers, one comprising a metal oxide such as zinc tin oxide and the other layer comprising a silicon compound, adjacent each of the two sides of the metal layer. This type of assembly may serve various purposes, including being used as a sun control film. These constructions may be used, for example, as window films on glazing units for reducing transmission of infrared radiation across the film in both directions.

Display stacks are disclosed. More specifically, display stacks including an emissive display including a plurality of organic light emitting diodes, a circular polarizer, and a color correction film disposed between the emissive display and the circular polarizer are disclosed. The color correction film includes a plurality of microlayers and may provide reduced color shift performance between on and off-axis viewing angles compared to display stacks not including the color correction film.

The present disclosure provides an article having a conductor micropattern disposed on a major surface of a substrate. The conductor micropattern includes a plurality of curved traces defining a plurality of cells not lying on a repeating array. The conductor micropattern may have a uniform distribution of trace orientation. The conductor micropattern may be a tri-layer material including in sequence a semi-reflective metal, a transparent layer, and a reflective layer disposed on the transparent layer. The articles are useful in devices such as displays, in particular, touch screen displays useful for mobile hand held devices, tablets and computers. They also find use in antennas and for EMI shields.
