An electrochromic device is provided. The device includes a first transparent substrate, a second transparent substrate, a first electrically conductive layer with a first resistance gradient arranged on an inner surface of the first transparent substrate, a second electrically conductive layer with a second resistance gradient arranged on an inner surface of the second transparent substrate. The device includes a first bus bar in contact with the first electrically conductive layer, a second bus bar in contact with the second electrically conductive layer, a first sense voltage pad arranged on the inner surface of the first transparent substrate configured to measure a local cell potential at a sense voltage measurement position within the electrochromic device, wherein the first and second resistance gradients are configured to form a region comprising a maximum local cell potential approximately coinciding with the sense voltage measurement position.

A privacy glazing structure may be fabricated from multiple panes of transparent material that hold an optically active material and also define a between-pane space that is separated from a surrounding environment for thermal insulating properties. The privacy glazing structure may include various functional coatings and intermediate films to enhance the performance and/or life span of the structure. For example, the privacy glazing structure may include a low emissivity coating and a laminate layer positioned between an optically active layer and an exterior environment exposed to sunlight. The low emissivity coating and laminate layer may work in combination to effectively protect the optically active layer from sunlight degradation. Additionally or alternatively, the laminate layer may impart safety and impact resistance properties to the structure.

A variable transmittance optical filter comprising: a first layer comprising a first substantially transparent substrate with a substantially co-planar (SC) electrode system disposed thereon, the SC electrode system made of transparent electrically conductive material and comprising at least one pair of electrically separate electrodes arranged in a substantially co-planar manner on the first substantially transparent substrate, each pair of electrically separate electrodes comprising a first electrode and a second electrode, a second layer proximate to the first layer and comprising a transition material that darkens in response to a non-electrical stimulus and lightens in response to application of an electric voltage; and an electrical connection system for electrically connecting the SC electrode system to a source of electric voltage.

A liquid crystal display device includes a first substrate, a second substrate facing the first substrate, a dual passivation layer disposed between the first substrate and the second substrate. The dual passivation layer includes a first passivation layer and a second passivation layer. A refractive index of the first passivation layer is different from a refractive index of the second passivation layer.

Methods and materials to fabricate electrochromic including electrochemical devices are disclosed. In particular, emphasis is placed on the composition, fabrication and incorporation of electrolytic sheets in these devices. Composition, fabrication and incorporation of redox materials and sealants suitable for these devices are also disclosed. Incorporation of EC devices in insulated glass system (IGU) windows is also disclosed.

The present disclosure relates to an optically transmissive window apparatus. The window may make use of a non-electrically conductive substrate and a transparent conductive oxide (TCO) material layer disposed on the non-electrically conductive substrate, which is transmissive to a selected wavelength or range of wavelengths. An electrically conductive grating-like structure is disposed on or formed on the TCO material layer. The electrically conductive grating-like structure has a plurality of parallel metallic traces spaced apart by a selected spacing distance and works to dramatically reduce the RF reflectivity of the TCO material layer without impairing the electrochemical operation of the TCO material layer.
