A device including a phosphor layer having a plurality of holes or pockets arranged within the phosphor layer to reduce lateral light transmission. The phosphor layer can be sized and positioned to extend over a plurality of LED emitter pixels.

Building cladding systems with changeable appearances and methods of use are described. The building cladding system may include a substrate and a coating comprising a switchable material. Varying a voltage, temperature, or wavelength of light on or applied to the coating may change an appearance of the building cladding system.

The present invention relates to a metal hydride device having a variable transparency, comprising a substrate, at least one layer including a photochromic yttrium hydride having a chosen band gap, and a capping layer at least partially positioned on the opposite side of the photochromic yttrium hydride layer from the substrate, said capping layer being essentially impermeable to hydrogen and oxygen.

An arbitrary waveform generation device is an arbitrary waveform generation device that generates, from an arbitrary waveform of a first electrical signal, an arbitrary waveform of a second electrical signal having a frequency higher than a frequency of the first electrical signal, and includes: a modulator that modulates, with the first electrical signal, an optical carrier wave which is dispersed to have a central wavelength that varies with time; a dispersion compensator that performs dispersion compensation on the optical carrier wave modulated with the first electrical signal; and a photoelectric converter that converts the optical carrier wave which has been dispersion-compensated into an electrical signal to generate the second electrical signal.

An information handling system display manages direction of illumination from an internal backlight to illuminate the display perimeter. A translucent material disposed between a liquid crystal display panel and backlight manages a color of backlight illumination applied at the display perimeter. In various alternative embodiments, the translucent material selectively adjusts light transmission characteristics to adjust light that passes to a frontside of the liquid crystal display panel.

The present invention provides a display panel and a display device. The display panel includes an array substrate, a color film substrate disposed on the array substrate, and a photochromic glass layer disposed on the color film substrate. A color change region is formed when an ultraviolet laser irradiates the photochromic glass layer, and the color change region filters passing lights. The display panel further includes a plurality of scattered particles distributed on the photochromic glass layer.

An apparatus comprising a switchable optical filter comprising a layer of switchable material, the switchable material comprising a photochromic/thermochromic, a photochromic/photochromic, or a photochromic/electrochromic compound; a first light source providing light of a wavelength that causes the switchable material to transition from a faded state to a dark state, or a dark state to a faded state; and a switch for controlling activation of the first light source.

This invention relates to a device for rapid focus control of one or more lasers. The controlled beam (5), is refracted by the dynamic refraction device (1) whose refractive index is set by its response to the control beam (3). The invention can be used for rapid focus and re-focus of a laser on a target as might be useful in such industries as flat panel television manufacturing, fuel injector nozzle manufacture, laser material processing/machining, laser scanning and indirect drive inertial confinement fusion.

A first LED with a first LED sidewall is disclosed. A second LED with a second LED sidewall facing the first LED sidewall is also disclosed. A first dynamic optical isolation material between the first LED sidewall and the second LED sidewall and configured to change an optical state based on a state trigger such that a light behavior at the first LED sidewall for a light emitted by one of the first LED and the second LED is determined by the optical state, is also disclosed.

Display systems include a display structure having a display surface, and an optical projector that is positioned relative to the display structure and that is configured to project an image onto the display surface. Vehicles include a display system and vehicle structures, in which one vehicle structure includes the display structure of the display system and another vehicle structure includes the optical projector of the display system. Display methods include projecting an image onto a display surface.
