According to one or more embodiments described herein, a coated article may comprise a transparent substrate and an optical coating. The transparent substrate may have a major surface, and the optical coating may be disposed on the major surface of the transparent substrate and form an air-side surface. The optical coating may comprise one or more layers of deposited material and one or more light-altering features which may reduce oscillations in the reflectance spectrum of the coated article. The coated article may exhibit a maximum hardness of about 8 GPa or greater, have an average photopic transmittance of about 50% or greater, and exhibit an angular color shift of less than about 10 from a reference illumination angle in a range of 0-10 degrees to an incident illumination angle in a range of 30-60 degrees relative to the air-side surface.

A transparent display includes nanoparticles having wavelength-selective scattering (e.g., resonant scattering) to preferentially scatter light at one or more discrete wavelengths so as to create images. The nanoparticles transmit light at other wavelengths to maintain a high transparency of the display. The nanoparticles are disposed in proximity to a thin film, which can enhance the scattering the process by reflecting light back to the nanoparticles for re-scattering or increasing the quality factor of the resonant scattering.

An optical brightness enhancement structure and a manufacturing method thereof and an electronic device are provided. The method for manufacturing an optical brightness enhancement structure includes: providing a light-transmissive carrier, and forming a buffer layer on a first surface of the light-transmissive carrier; forming a plurality of microstructures for converging light on a surface of the buffer layer away from the light-transmissive carrier; and surface energy of each of the microstructures is greater than surface energy of the buffer layer.

An optical film includes a substrate, an absorption pattern and a scattering reflection layer. The substrate has a contact surface and a back surface opposite the contact surface, wherein the substrate allows a first light to pass and is made of a non-rigid material. The absorption pattern is arranged on the contact surface of the substrate to absorb the first light. The scattering reflection layer is arranged on the back surface of the substrate to scatter and reflect the first light to the contact surface of the substrate. The foregoing optical film enables an optical reader device to detect variations of the reflected first light, which is caused by deformation of the substrate, so that the corresponding force information can be obtained. A user input system including the foregoing optical film is also disclosed.

An optical film comprises a first transparent film substrate, a matte layer arranged on the first transparent film substrate and having irregularities, the matte layer having a coefficient of static friction of not larger than 0.3 and a maximum height roughness Rz of not less than 0.05 μm to not larger than 8 μm.

An optical coating structure applied to the surface of an object having scattering structures introduced to the basal, upper or middle layers of a multilayer reflector to cause a particular (calculated) degree of scattering, or to the surface of a black/colour pigmented object. The scattering structures are mainly sub-micron in size, and arranged in a pseudo-random or non-periodic manner. Consequently they serve only to broaden the angular range of the light reflected at the surface normal from a multilayer reflector, or to provide (actual and/or perceived) reduced reflectivity of a surface by deflecting incident light through the surface rather than away from it or by scattering otherwise beam-like (narrow-angle) reflections from a surface into a broad-angle reflection. The scattering structures can include profile elements, which are in the form of elongate bars having convexly curved sides or hemispherical rods, that are introduced to a basal layer of a multilayer reflector.

An optical film comprises a first transparent film substrate, a matte layer arranged on the first transparent film substrate and having irregularities, the matte layer having a coefficient of static friction of not larger than 0.3 and a maximum height roughness Rz of not less than 0.05 μm to not larger than 8 μm.

To obtain a white reflective film that is hard to warp and can ameliorate unevenness in the luminance even when used in such a manner as to be superimposed on a chassis having convex and concave portions for placing circuits and the like or used with an LED, and can prevent uneven close contact with a light guide plate and damage of the light guide plate, the white reflective film for edge-lit backlight is made to meets the requirements (i) to (iii): (i) the stiffness is 2 to 10 mN.Math.m; (ii) convex portions are formed on at least one surface (A) and the maximum height of the convex portion is 15 to 60 μm; and (iii) the cushion rate at the side of a surface (B) opposite to the surface (A) is 12% or more.

An optical film including a first film substrate and a coating layer formed on the first film substrate. The coating layer of this optical film contains a binder resin and fine particles with an average size of 0.5 μm or more and 10.0 μm or less and a standard deviation in size that is less than ½ of the average size.

An optical coaling structure is provided that when applied to a surface of an object to imparts a color to the object, the optical coating structure including: a base layer; a reflector on the base layer; and profile elements on the base layer under the reflector, the profile elements having a width and length which are each in the range of 5 to 500 μm in size, and being arranged in non-periodic manner or a periodic manner. The reflector may be a multilayer structure of alternating dielectric materials. A method of forming the optical coating structure is also provided.
