Techniques for creating, configuring, and employing diffusion light devices are presented. Such light device(s) can comprise or be associated with a light management component (LMC) that can employ sensors to monitor environmental conditions in a defined area of people or vehicles, and a diffusion component that can diffuse or otherwise process light. At a least a portion of the diffusion component and/or a light component can be formed of a fabric that can emit light and/or diffuse light. LMC can enhance function of the light device to manage diffusion of light or perform other tasks to enhance user experience and safety and security of people or vehicles. Based on results of analyzing sensor data relating to the conditions, LMC can determine and facilitate implementing an adjustment(s) to a parameter(s) of the diffusion component or light component to achieve desired emission or diffusion of light.

A textured enclosure component including two different types of surface features is disclosed. The two different types of surface features are differently sized. The combination of differently sized surface features provides both anti-glare and anti-reflective properties to the enclosure component.

A diffusion film is provided, including a matrix material including a reaction product of following components: a polythiol, a polyolefin, and a crosslinking agent having thiol and alkenyl functional groups; a photoluminescence material including at least a quantum dot or at least a fluorescent powder; and light diffusion particles including organic polymer particles and/or inorganic particles.

An article includes a substrate with a surface, and a coating disposed over the surface. The coating includes a binder material and a plurality of UV scattering porous polymer particles having pores with a light scattering effective pore size of no more than 100 nm. The coating has a scattering opacity of no more than 20% in the wavelength band from 500 to 3000 nm.

A curved screen comprises the following layers sequentially arranged from inside to outside: a black light-absorbing layer, a microstructure array layer, and a transparent matrix layer. The microstructure array layer consists of a plurality of microstructure units. The microstructure unit is a V-shaped recess consisting of two intersecting inclined surfaces. The microstructure array layer is rotationally symmetrical with respect to a center line of the curved screen. Angles of the V-shaped recesses in respective longitudinal cross sections of the curved screen are uniquely determined according to incident angles of light rays from a projector. Also disclosed are a method of arranging microstructures in the curved screen and a projection system comprising the curved screen. The curved screen has a higher contrast, improved brightness uniformity and an enlarged field of view.

Various embodiments of the present technology generally relate to reflection suppressors. More specifically, some embodiments use elastomeric materials doped with optical absorbers for temporary suppression of Fresnel reflections for multiple substrates spanning wide spectral and angular bandwidth. The refractive index of the elastomer can be tuned to match a substrate and thereby minimize reflection. Some embodiments can use the addition of different absorptive dopants to allow for either broadband or wavelength-selective reflection suppression. As performance is limited only by index mismatch, both spectral and angular performance significantly exceed that of anti-reflection coatings. After use, these light traps may be removed and reused without damaging the substrate. These films have uses in spectroscopic ellipsometry, holography, and lithography.

An apparatus for wafer processing includes a wafer pedestal configured to support a wafer, a radiation source configured to provide an electromagnetic radiation to the wafer, and a transparent window disposed between the wafer pedestal and the radiation source. The transparent window has a first zone having a first rough surface, and an Ra value of the first rough surface is between approximately 0.5 μm and approximately 100 μm. The apparatus for wafer processing further includes a primary reflector disposed in the radiation source, and a secondary reflector disposed between the transparent window and the radiation source. The rough surface can be provided over the transparent window, the primary reflector, and/or the secondary reflector.

A multilayer optical film including: an A layer formed of an alicyclic structure-containing polymer resin; and a B layer disposed on at least one surface of the A layer to be in direct contact therewith, the B layer serving as a masking layer, wherein the B layer is a cured product of a material Y including a dispersion of a crosslinkable polymer (a) and solid particles (b), and the B layer has a thickness tB of 10 μm or more and 25 μm or less. A production method including the steps of applying the material Y onto a surface of the A layer, to form a layer of the material Y; and curing the layer of the material Y.

An LED display screen, comprising: an LED array, consisting of multiple LED light-emitting units and used for emitting a light; an optical diffusion film, provided at a light exit side of the LED array; a matrix shading frame, comprising multiple hollow shading gratings, the hollow shading gratings corresponding one-to-one to the LED light-emitting units; and a substrate, used for supporting the LED array and the matrix shading frame, where the light emitted by the LED light-emitting units, after running through the hollow shading gratings, is diffused to a viewer side via the optical diffusion film, and the LED light-emitting units emit the light towards the hollow shading gratings. The LED display screen prevents external ambient lights from being shone to optical surfaces of the LED light-emitting units and being reflected thereby, thus increasing the contrast of the LED display screen.
