摘要： A variably transmissive electro-optic window that has an easily tunable dynamic range is disclosed. The window comprises a first substrate, a second substrate, a first electrode, a second electrode, an electro-optic medium, and at least one tuning layer. The first substrate has a first and a second surface. The first surface is in a first direction relative the second surface. The second substrate has a third and a fourth surface. The third surface is disposed in the first direction relative the fourth surface. The second substrate is disposed in a second direction opposite the first direction relative the first substrate. The second substrate is additionally disposed in a substantially parallel and spaced apart relationship with the first substrate. The first electrode is disposed in the second direction relative the first substrate. The second electrode is disposed in the first direction relative the second substrate. The electro-optic medium is disposed between the first and second electrodes. Additionally, the electro-optic medium is operable to vary a transmittance of light therethrough. Lastly, a tuning layer is substantially transparent and operable to attenuate the transmittance of visible light therethrough.

摘要： An electro-optic element comprises a first substrate; a second substrate generally parallel to the first substrate; a first bus having a first bus segment disposed on an inner surface of the first substrate and extending along a first portion of a perimeter of the first substrate and a second bus segment disposed on an inner surface of first substrate and extending along a second portion of the perimeter of the first substrate. The second bus segment is in a spaced apart relationship with first bus segment. A second bus has a third bus segment and a fourth bus segment is disposed on the second substrate, each extending along a portion of the perimeter of the second substrate. A controller is configured to be in selective electrical communication with first and second buses and to independently control a voltage applied to each of the bus segments.

摘要： An electro-optic window comprises a first substrate; an electro-optic element generally parallel to the first substrate, the electro-optic element comprising: a second substrate; a third substrate generally parallel to the second substrate; a sealing member disposed along at least a portion of a perimeter of one of the second and third substrates and extending therebetween; and a cavity defined between the second and third substrates. The sealing member defines the sidewalls of the cavity. A first layer of film having a perimeter portion and a central portion is disposed between at least a portion of the first and second substrates, and may be coextensive with the sealing member.
