Electrochromic structures |
摘要 |
Electrochromic windows and panels are provided which have first and second spaced elements that are optically transparent to visible light. The first and second elements each have first and second sides, and the windows and panels define a sealed chamber disposed between the second side of the first element and the first side of the second element. The sealed chamber is filled with an electrochromic medium, and the transmission of visible light through the electrochromic medium is variable when an electrical potential is applied to electrically conductive coatings that are provided on the second side of the first element and the first side of the second element. A layer partially transmissive of visible light and partially reflective of visible light is provided on one of the sides of the first or second elements so that the application of electrical potential to the electrochromic medium causes variations in the visible light transmitted through the partially visible light transmissive and partially visible light reflective layer and through the electrochromic medium whereby privacy and changes in visible color of the electrochromic medium may be either enhanced in one embodiment of the invention or hidden in another embodiment of the invention.
