Thin-film coatings, electro-optic elements and assemblies incorporating these elements
First Claim
1. An electro-optic element, comprising:
- a first substrate including a perimeter length and first and second surfaces, the first substrate containing at least a first layer of electrically conductive material deposited on the second surface, wherein the first layer is substantially transparent;
a second substrate including third and fourth surfaces, the second substrate containing a second layer of electrically conductive material deposited on the third surface, wherein the first and second substrates are disposed in a parallel and spaced-apart relationship to define a gap between the second and third surfaces, the gap containing an electro-optic medium; and
a first bus with a first bus length that is arranged in electrical communication with the first layer,wherein a contact percentage between the first bus length and the perimeter length is greater than about 40%, andfurther wherein the element is configured such that a relative darkening timing factor substantially across the element is less than a factor of 3, the relative darkening timing factor given by a darkening time at a position within the element divided by a fastest darkening time within the element.

Abstract
An electro-optic element comprises a first substrate, including first and second surfaces. The first substrate contains at least a first layer of electrically conductive material that is deposited on the second surface and is substantially transparent. The element also comprises a second substrate including third and fourth surfaces, the second substrate containing a second layer of electrically conductive material deposited on the third surface. The first and second substrates are disposed in a parallel and spaced-apart relationship to define a gap between the second and third surfaces, the gap containing an electro-optic medium, and each substrate with a width and a height such that the ratio of width to height is less than or equal to 2. In addition, the element is configured such that a relative darkening timing factor substantially across the element is less than a factor of 3.
