An apparatus is disclosed that includes a switchable optical filter having a layer of switchable material; a 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 light source.

Optical filter with light source

A packaged film assembly includes a packaging material and a switchable film. The switchable film is packaged in and attached to at least a portion of the packaging material.

Packaged film assembly for lamination between substrates

The disclosure provides, in part a seal system for sealing a film. The disclosure further provides, in part, a sealed film comprising a first and a second substrate; a first and a second electrode disposed on the surface of at least one of the substrates; a switching material disposed between the first and second substrates; a first seal and a second seal; the first seal disposed along an edge of the switching material, separating the switching material from the second seal.

Seal and seal system for a layered device

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.

A simplified switchable object and methods of making same are provided. The methods may include steps of applying a switchable material on a first surface of a first substrate, the switchable material having a thickness and a shape; applying a barrier material on the first substrate, circumferential to the switchable material; and applying a second substrate over top of, and in contact with, the switchable material and the barrier material, the first substrate, second substrate and barrier material defining a closed chamber encapsulating the switchable material. The methods may further include a step of applying a seal material.

Switchable objects and methods of manufacture

An optical filter comprising a variable transmittance layer having a first spectrum in a dark state, and a second spectrum in a faded state; and a color balancing layer having a third spectrum; each of the first, second and third spectra comprising a visible portion; the first and third spectra combining to provide a dark state spectrum approximating a dark state target color, and the second and third spectra combining to provide a faded state spectrum approximating a faded state target color. The optical filter may further comprise a light attenuating layer. The optical filter may further comprise part of a laminated glass.

Optical filter comprising a variable transmittance 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

A composition comprising a diarylethene photochromic anodic species, a cathodic species and an electrolyte that comprises a supporting electrolyte and a solvent. Electrochromic devices such as optical filters are prepared from such compositions.

Photochromic-electrochromic compositions

A optical filter comprising a variable transmittance layer having a first spectrum in a dark state, and a second spectrum in a faded state; and a color balancing layer having a third spectrum; each of the first, second and third spectra comprising a visible portion; the first and third spectra combining to provide a dark state spectrum approximating a dark state target color; and the second and third spectra combining to provide a fades state spectrum approximating a faded state target color. The optical filter may further comprise a light attenuating layer. The optical filter may further comprise part of a laminated glass.

A layered structure for a variable transmittance optical filter includes a transparent conductive electrode and a substrate layer. The transparent conductive electrode includes a charge injection layer that has one or more of gold, molybdenum, palladium, reduced graphene oxide, amorphous indium gallium zinc oxide (a-IGZO), platinum, nickel, ruthenium, rhodium, asmium, selenium, tellurium, graphene, and carbon nanotubes. The substrate layer includes a transparent substrate and is positioned relative to the transparent conductive electrode such that light passing through the transparent conductive electrode passes through the substrate layer.

Layered transparent conductive electrode structure for an optical filter

A switching material comprising one or more than one polymers and an electrolyte comprising a salt and a solvent portion comprising one or more solvents; and one or more compounds having electrochromic and photochromic properties dispersed homogeneously through the switching material; and wherein the switching material is transitionable from a light state to a dark state on exposure to UV light and from a dark state to a light state with application of an electric voltage.
