An electro-optic apparatus configured to adjust in transmittance in response to a control input comprises a first web substrate and a second web substrate. Each of the web substrates form a plurality of perimeter edges. A first edge is in connection with a first electrical terminal connecting in connection with a first electrode. A second edge opposing the first edge is in connection with a second electrical terminal in connection with a second electrode. A third edge and an opposing fourth edge comprise a barrier seal in a first configuration in connection with an exterior surface of each of the first web substrate and the second web substrate. The barrier seal encapsulates the electro-optic medium between an interior surface of each of the first web substrate and the second web substrate.

Electro-optic apparatus and seal system

An electrochromic device includes a cathodic compartment including a cathodic material; an anodic compartment including an anodic material; and a transparent, ion-selective membrane displaced between the cathodic compartment and the anodic compartment wherein the transparent, ion-selective membrane is a cationic polymer.

Electro-optical device having a transparent ion exchange membrane

An electrochromic device includes a flexible plastic substrate including a front surface, and a rear surface, wherein the rear surface comprises a first conductive material; and a rigid plastic substrate including a front surface, and a rear surface, wherein the front surface comprises a second conductive material, wherein the first substrate is joined to the second substrate by a sealing member, wherein the rear surface of the first substrate and the front surface of the second substrate with the sealing member define a chamber therebetween.

Electrochemical devices with plastic substrates

An illumination assembly configured to emit diffuse light through an indicator is disclosed. The assembly comprises a substrate having an applique disposed thereon. The applique forms an opening configured to transmit light through the substrate. The assembly further comprises a light source in connection with a circuit and configured to emit light through the shape. A diffusing layer is applied to a surface of the assembly between the circuit and the substrate. The diffusing layer comprises a resin material configured to cure in response to exposure to ultraviolet light or heat. The diffusing layer further comprises a filler material comprising a plurality of beaded structures configured to diffuse light from the light source.
