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.
