SEGMENTED VARIABLE CONTROLLED ELECTRO-OPTIC ELEMENT

Abstract:

An electro-optic element includes first and second spaced-apart transparent substrates defining respective opposite, aligned first and second edges, a first bus including a first electrode disposed along an inner surface of the first substrate adjacent the first edge and a second electrode disposed along an inner surface of the second substrate adjacent the first edge, and a second bus including a first electrode disposed along an inner surface of the first substrate adjacent the second edge and a second electrode disposed along an inner surface of the second substrate adjacent the second edge. The first bus and second bus are spaced apart along widths of the first and second substrates between the respective first and second edges. An electro-optic medium is disposed between the first and second transparent substrates, including between the first and second electrodes of the first bus and the second bus, respectively.
