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.
