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.

First claim

1 - 19 . (canceled)

20 . An insulated glass unit (IGU) comprising:
a. a pair of parallel lites; b. a spacer between the parallel lites; and c. a seal between each of the parallel lites and the spacer;
wherein at least one lite of the pair of parallel lites comprises a set of independently controllable electrochromic zones, wherein each zone is an isolated area of a solid state electrochromic device on the at least one lite, wherein the solid state electrochromic device comprises a physical vapor deposition layer, a pyrolytic layer, a wet-chemical layer or a vacuum-coated layer.

21 . The IGU of claim 20 , wherein the independently controllable electrochromic zones are formed by laser ablation of a monolithic electrochromic device coating.

22 . The IGU of claim 20 , wherein each zone of the set of independently controllable electrochromic zones has an associated pair of bus bars.

23 . The IGU of claim 20 , wherein each zone of the set of independently controllable electrochromic zones has a distinct pair of associated bus bars.

24 . The IGU of claim 20 , further comprising an inert gas in a sealed volume formed between the pair of parallel lites and the spacer.

25 . The IGU of claim 21 , wherein the monolithic electrochromic device coating comprises a sputtered layer.

26 . The IGU of claim 21 , wherein the monolithic electrochromic device coating comprises a sol gel layer.

27 . The IGU of claim 20 , wherein the at least one lite of the pair of parallel lites comprises a low-E coating or a reflective coating.

28 . The IGU of claim 20 , wherein the at least one lite of the pair of parallel lites comprises a light scattering feature.

29 . The IGU of claim 20 , wherein the at least one lite of the pair of parallel lites comprises a photochromic or a thermochromic material.
