Abstract
Thin-film devices, for example, multi-zone electrochromic windows, and methods of manufacturing are described. In certain cases, a multi-zone electrochromic window comprises a monolithic EC device on a transparent substrate and two or more tinting zones, wherein the tinting zones are configured for independent operation.
Claims25
An electrochromic (EC) window comprising:
- an EC device on a transparent substrate, the EC device comprising bus bars;
- a region of the transparent substrate that is not covered by the EC device, the region capable of providing, when not mitigated, a bright spot or bright region when the EC device is tinted;
- and
- an obscuring material over the region, wherein the obscuring material has a lower transmittance than the transparent substrate,
- wherein the obscuring material comprises a thermochromic material.
2 more elements
A method of obscuring a bright area produced by a region of a transparent substrate that is not covered by an EC device, the method comprising:
- i. providing an electrochromic lite having the EC device on a substrate;
- ii. identifying a site of the bright area on the substrate;
- and
- iii. applying an obscuring material over the site, wherein the obscuring material has a lower transmittance than the substrate,
- wherein the obscuring material comprises a thermochromic material.
