Abstract
A switchable device for changing the opacity of at least a portion of a glazing is described. The switchable device comprises at least two (a first and a second) switchable regions in electrical communication with at least two (a first and a second) electrical connector regions. Each switchable region comprises an electrically actuated variable opacity layer between a first electrode and a second electrode, the first switchable region being arranged relative to the second switchable region such that upon connecting the first and second electrical connector regions to a suitable power supply, the opacity of the first and second switchable region changes such that at least two (a first and a second) portions of the switchable device have a change of opacity, the first portion of the switchable device having a different opacity to the second portion of the switchable device.
