Abstract: An electro-optic element includes a first substrate that has a first surface and a second surface substantially opposite the first surface. A second substrate has a third surface and a fourth surface substantially opposite the third surface. The second substrate is disposed in a spaced apart manner relative the first substrate such that the second and third surfaces face one another. A plurality of spacer beads are disposed between the second surface and the third surface. The plurality of spacer beads are formed of a material that is soluble in propylene carbonate and does not contain salt or polymers. A first substantially transparent electrode is associated with the second surface and a second substantially transparent electrode is associated with the third surface. An electro-optic medium contains propylene carbonate disposed between the first and second substantially transparent electrodes.

Abstract: A transparent photovoltaic (TPV) integrated directly into the structure of an electrochromic (EC) device is beneficial in that it can eliminate at least one substrate and provide more uniform coloring. Integration of a transparent photovoltaic with an electrochromic device may also reduce or eliminate the need for an electrical bus on a substrate. In some embodiments, positioning the TPV internally with the EC cell may eliminate the need for additional substrate layers or a conductive layer on one side of the TPV cell. Integrating a PV cell into the EC device can additionally reduce the need for external wiring and an external power supply. Alternatively, the TPV can assist in charging a battery where the battery can be used to power the EC device when there is no sunlight available.

Abstract: An emissive display system includes an electro-optic device having a first substantially transparent substrate. A second substantially transparent substrate is spaced apart from the first substrate to define a cavity therebetween. 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. One or more spacing members are deposited on one of the first substrate and the second substrate and are configured to maintain a cell spacing between the first and second substrates. The one or more spacing members at least substantially dissolve upon association with the electro-optic medium. 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.
