Abstract
Electrochromic structures, such as windows and panels, are provided wherein privacy and changes in the color of an electrochromic medium incorporated in the structures may be either enhanced or hidden when viewed from a predetermined direction, as for example, when viewed from the outside of a building or when viewed from one side of a transparent interior panel in a building.
Claims24
An electrochromic structure comprising:
- a first element having a first side and a second side;
- a second element having a first side and a second side, said first side of said second element confronting said second side of said first element, said first and second elements being spaced apart to define a chamber therebetween;
- a first electrically conductive layer carried on said second side of said first element;
- a partially reflective electrically conductive layer carried on said first side of said second element;
- and
- an electrochromic medium in said chamber and electrically coupled with said first electrically conductive layer and said partially reflective electrically conductive layer.

An electrochromic architectural window for a building structure, said window comprising:
- a first element having a first side and a second side, said first side of said first element configured to face the inside of the building structure;
- a second element having a first side and a second side, said first side of said second element confronting said second side of said first element, said first and second elements being spaced apart to define a chamber therebetween, said second side of said second element configured to face the outside of the building structure;
- a first electrically conductive layer carried on said second side of said first element;
- a partially reflective electrically conductive layer carried on said first side of said second element;
- and
- an electrochromic medium in said chamber and electrically coupled with said first electrically conductive layer and said partially reflective electrically conductive layer.

An electrochromic architectural window for a building structure, said window comprising:
- a first transparent element having a first side and a second side, said first side of said first element configured to face the inside of the building structure;
- a second transparent element having a first side and a second side, said first side of said second element confronting said second side of said first element, said first and second elements being spaced apart to define a chamber therebetween, said second side of said second element configured to face the outside of the building structure;
- a first transparent electrically conductive layer carried on said second side of said first element;
- a second transparent electrically conductive layer carried on said first side of said second element;
- a partially reflective layer carried on said second side of said second element, said partially reflective layer partially reflecting visible light impinging upon the window from the outside of the building structure;
- and
- an electrochromic medium in said chamber and electrically coupled with said first and second transparent electrically conductive layers.
