    Abstract: 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.

    Abstract: A driver (60) may be used to drive an electrically controllable optically active material in a privacy structure (12). In some examples, the driver receives power from a power source (62) at a supply voltage and a supply apparent power level and converts the power received from the power source down to a converted voltage and a converted apparent power level. The converted voltage is less than the supply voltage and the converted apparent power level is less than the supply apparent power level. The driver may deliver power at the converted voltage and the converted apparent power level to a voltage converter (64) which increases the converted voltage to an operating voltage. The driver can further condition power received from the voltage converter having the operating voltage and operating apparent power level to provide a drive signal and provide the drive signal the electrically controllable optically active material of the privacy structure.

    Abstract: A privacy glazing structure may include an electrically controllable optically active material that provides controlled transition between a privacy or scattering state and a visible or transmittance state. To make electrical connections with electrode layers that control the optically active material, the privacy glazing structure may include an offset pane arrangement. The structure may include first and second panes that contain an optically active material. The two panes may be sandwiched by two laminated outer panes. In some examples, the first and second panes are recessed relative to the laminated outer panes along their side edges to define recesses in which electrical connection features are positioned. While the side edges may be recessed, the bottom edges of all the panes may be positioned flush with each other.

    Abstract: A privacy glazing structure may include an electrically controllable optically active material, such as a liquid crystal material, sandwiched between a flexible substrate and a rigid substrate. The flexible substrate and the rigid substrate may each have a conductive layer deposited on the surface facing the optically active material. The flexible substrate may be bonded about its perimeter to the rigid substrate and may be sufficiently flexible to conform to non-planarity of the rigid substrate. As a result, the flexible substrate may adopt the surface contour of the rigid substrate to maintain a uniform thickness of optically active material between the flexible substrate and the rigid substrate.
