  • Publication number: 20200183244
    Abstract: 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.

  • Patent number: 10343608
    Abstract: A rearview assembly having an electrochromic element. A front substrate defines a first surface and a second surface. A front side edge is disposed between the first surface and the second surface. A rear substrate is operably coupled with the front substrate and spaced a predetermined distance therefrom. The rear substrate defines a third surface and a fourth surface. A rear side edge is disposed between the third surface and the fourth surface. A perimeter of the rear substrate is larger than a perimeter of the front substrate, such that an outer portion of the third surface is exposed, thereby defining a peripheral step between the front side edge and the rear side edge. An electrochromic material is disposed between the front substrate and the rear substrate. A bezel is configured to extend around the rear substrate, over the outer portion of the third surface.
