Abstract: An electro-optic assembly includes a first substrate that has a first surface and a second surface that is opposite the first surface. A second substrate has a third surface and a fourth surface that is opposite the third surface. The first and second substrates are disposed in a parallel and spaced apart relationship so as to define a cavity therebetween. The second and third surfaces face each other. A seal extends between the first and second substrates. An electro-optic medium is located in the cavity and is retained by the seal. A port is at least partially defined by a port reduction member that is located between the first substrate and the second substrate.

Abstract: An electro-optic assembly comprises a first substrate and a second substrate. The first and second substrates are disposed in a parallel and spaced apart relationship so as to define a cavity therebetween. A primary seal extends between the first and second substrates. An electro-optic medium is located in the cavity and retained in an inboard direction by the primary seal. A plurality of first spacer elements are coupled to the primary seal. A break wall is located in the inboard direction or an outboard direction from the primary seal. The break wall extends between the first and second substrates and generally along the primary seal. A plurality of second spacer elements are coupled to the break wall. A space is defined between the primary seal and the break wall in the inboard-outboard directions.

Abstract: An electro-optic element includes first and second spaced-apart transparent substrates defining respective opposite, aligned first and second edges, a first bus including a first electrode disposed along an inner surface of the first substrate adjacent the first edge and a second electrode disposed along an inner surface of the second substrate adjacent the first edge, and a second bus including a first electrode disposed along an inner surface of the first substrate adjacent the second edge and a second electrode disposed along an inner surface of the second substrate adjacent the second edge. The first bus and second bus are spaced apart along widths of the first and second substrates between the respective first and second edges. An electro-optic medium is disposed between the first and second transparent substrates, including between the first and second electrodes of the first bus and the second bus, respectively.
