Abstract: An electro-optic element comprises a first substrate, including first and second surfaces. The first substrate contains at least a first layer of electrically conductive material that is deposited on the second surface and is substantially transparent. The element also comprises a second substrate including third and fourth surfaces, the second substrate containing a second layer of electrically conductive material deposited on the third surface. The first and second substrates are disposed in a parallel and spaced-apart relationship to define a gap between the second and third surfaces, the gap containing an electro-optic medium, and each substrate with a width and a height such that the ratio of width to height is less than or equal to 2. In addition, the element is configured such that a relative darkening timing factor substantially across the element is less than a factor of 3.

Abstract: An electrochromic device that may have an elastomeric seal is disclosed as is an electrochromic device having a seal provided on the peripheral edges of both the front and rear elements and wherein the seal may comprises a first material having an oxygen permeability of less than about 2.0 cm3·mm/m2·day·atm. In addition, an electrochromic device may include a seal comprising a thin member bonded to the peripheral edge of at least one of the front and rear elements, wherein the thin member comprises one of a film, thin glass, and a strip of foil.

Abstract: To allow an electrochromic device to have little or no offset between its front and rear elements, an electrical conductor may be provided to electrically couple a portion of a first conductive layer provided on the rear surface of the front element with a portion of a second conductive layer provided on the front surface of the rear element. The electrical conductor may be in the form of a conductive portion of the seal. To prevent shorting across the electrochromic medium, at least one of the first and second conductive layers is separated into a first portion and a second portion that is electrically isolated from the first portion and is in electrical contact with the electrochromic material. An elastomeric bezel may be utilized. Also, an edge seal may optionally be employed so as to reduce the need or width of the bezel.
