Patent Images
1. A multi-zone dynamic window, comprising:
- two or more independently-controllable electrochromic zones on a single substrate through which light can pass, wherein the two or more independently-controllable electrochromic zones are formed from a single electrochromic-based coating on the single substrate;
a plurality of bus bars on the single substrate, configured to apply voltage to the two or more independently-controllable electrochromic zones, wherein each of the two or more independently controllable zones has a pair of associated bus bars of the plurality of bus bars; and
an electrically-isolating area between adjacent electrochromic zones.

Abstract
A window assembly comprises a plurality of dynamic electrochromic zones formed on a single transparent substrate in which at least two electrochromic zones are independently controllable. In one exemplary embodiment, the window assembly comprises an Insulated Glass Unit (IGU), and at least one transparent substrate comprises a lite. In another exemplary embodiment, the IGU comprises at least two lites in which at least one lite comprises a plurality of independently controllable dynamic zones.
