    Abstract: An electro-optic element having enhanced durability by the addition of an additive. The additive may enhance the durability of the electro-optic element by reducing or eliminating the effects of water on species with the electro-optic element, such as the electrolyte. Specifically, the additive may operate to reduce or eliminate the formation and/or accumulation of hydrogen fluoride within the electro-optic element by interaction of the electrolyte with water or alcohol molecules. In some embodiments, the additive may be an organosilicon species, such as (3-cyanopropyl) dimethylfluorosilane.

    Abstract: An electro-optic element includes a first electroactive compartment including an electroactive film having a first electroactive component and a second electroactive compartment including an electroactive solution or gel having a second electroactive component. An ion selective material is disposed between the first and second electroactive compartments and is configured to inhibit diffusion of the second electroactive component in an activated state from the second electroactive compartment to the first electroactive compartment. At least one of the first and second electroactive components is electrochromic such that the electro-optic element is configured to reversibly attenuate transmittance of light having a wavelength within a predetermined wavelength range when an electrical potential is applied to the electro-optic element.

    Abstract: An emissive display system includes an electro-optic device having a first substantially transparent substrate including a first electrically conductive material associated therewith. A second substantially transparent substrate is spaced apart from the first substrate to define a cavity and includes a second electrically conductive material associated therewith. One or more spacing members are positioned within the cavity and include one or more polymer matrix discs configured to maintain a cell spacing between the first and second substrates. An electro-optic medium is disposed within the cavity and is variably transmissive such that the electro-optic device is operable between substantially clear and darkened states, and includes at least one solvent, at least one anodic material, and at least one cathodic material. A substantially transparent light emitting display is operably coupled to the electro-optic device, which is in the darkened state when the light emitting display is emitting light.
