HIGH-HAZE ANTI-GLARE FILM AND HIGH-HAZE ANTI-GLARE ANTI-REFLECTION FILM
A high-haze anti-glare film is disclosed. The high-haze anti-glare film comprises a transparent substrate and an anti-glare layer on the substrate. The anti-glare layer comprises acrylate binder resin and amorphous silica microparticles.

A laminate used under an environment irradiated with external light includes a light diffusion control film having an internal structure in the film. The internal structure includes a plurality of regions having a relatively high refractive index in a region having a relatively low refractive index.

ENERGY HARVESTING METHODS FOR PROVIDING AUTONOMOUS ELECTRICAL POWER TO MOBILE DEVICES
A method is provided that integrates an autonomous energy harvesting capacity in a mobile device in an aesthetically neutral manner. A unique set of structural features combine to implement a hidden energy harvesting system on a surface of the mobile device body structure or casing to provide electrical power to the mobile device, and/or to individually electrically-powered components in the mobile device. Color-matched, image-matched and/or texture-matched optical layers are formed over energy harvesting components, including photovoltaic energy collecting components. Optical layers are tuned to scatter selectable wavelengths of electromagnetic energy back in an incident direction while allowing remaining wavelengths of electromagnetic energy to pass through the layers to the energy collecting components below. The layers appear opaque when observed from a light incident side, while allowing at least 50%, and as much as 80+%, of the energy impinging on the energy or incident side to pass through the layer.
METHODS FOR MAKING COMPOSITIONS OF MATERIALS FOR FORMING COATINGS AND LAYERED STRUCTURES INCLUDING ELEMENTS FOR SCATTERING AND PASSING SELECTIVELY TUNABLE WAVELENGTHS OF ELECTROMAGNETIC ENERGY
Methods are provided for forming a particular multi-layer micron-sized particle that is substantially transparent, yet that exhibits selectable coloration based on its physical properties. The disclosed physical properties of the particle are controllably selectable refractive indices to provide an opaque-appearing energy transmissive material when pluralities of the particles are suspended in a substantially transparent matrix material. Multiply-layered (up to 30+ constituent layers) particles result in an overall particle diameter of less than 5 microns. The material suspensions render the particles deliverable as aspirated or aerosol compositions onto substrates to form layers that selectively scatter specific wavelengths of electromagnetic energy while allowing remaining wavelengths of the incident energy to pass. The disclosed particles and material compositions uniquely implement optical light scattering techniques in energy (or light) transmissive layers that appear selectively opaque, while allowing 80+% of the energy impinging on the light incident side to pass through the layers.

An anti-glare film is attached on a surface of a display, and includes an anti-glare layer. The anti-glare layer is set to have a sparkle value falling within a range from 6 to 10, which is defined based on a value of a standard deviation of luminance distribution of the display under a state in which the anti-glare film is attached on the surface of the display, a value of specular gloss of 30% or less, which is measured with 60-degree specular gloss, a value of transmission image clarity of 60% or less, which has an optical comb of 0.5 mm, and a haze value of 50% or less. Consequently, satisfactory anti-glare property can be provided while appropriately suppressing sparkle on the display.
