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.
Claims37
An electrochromic device comprising:
- a front element having a peripheral edge, a front surface, and a rear surface having a first layer of electrically conductive material disposed thereon;
- a rear element having a peripheral edge, a front surface, and a rear surface, said front surface of said rear element having a second layer of electrically conductive material disposed thereon;
- an electrochromic material;
- and
- a seal provided to sealably bond said elements together to define a chamber in which said electrochromic material is disposed, wherein said seal is provided on the peripheral edges of both said front and rear elements and wherein said seal comprises a first material having an oxygen permeability of less than about 2.0 cm3·mm/m2·day·atm.
An electrochromic device comprising:
- a front element having a peripheral edge, a front surface, and a rear surface having a first layer of electrically conductive material disposed thereon;
- a rear element having a peripheral edge, a front surface, and a rear surface, said front surface of said rear element having a second layer of electrically conductive material disposed thereon;
- an electrochromic material;
- and
- a seal provided on both said front and rear elements to sealably bond said elements together to define a chamber in which said electrochromic material is disposed, wherein said seal comprises a thin member bonded to the peripheral edge of at least one of said front and rear elements, wherein said thin member comprises one of a film, thin glass, and a strip of foil.
