Abstract: A film contains an electrically actuated liquid having variable optical opacity under the influence of an electric field. The film comprises first and second spaced apart substrates defining a first cavity therebetween in which some or all of the liquid is contained. The film also comprises a liquid trap in fluid communication with the first cavity via a first opening. The liquid trap contains liquid that may flow from the first cavity through the first opening due to the volume of first cavity decreasing. The film may be included in a laminated glazing. A method of preparing a cell for a liquid is also described, and such a cell may be part of a film having variable optical opacity.

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.

Abstract: A laminated glazing pane is described comprising first and second sheets of glazing material joined by an interlayer structure comprising at least one sheet of adhesive interlayer material. Each sheet of glazing material has respective first and second major surfaces and the laminated glazing is arranged such that the second major surface of the first sheet of glazing material faces the first major surface of the second sheet of glazing material. An illumination device is arranged relative to the first sheet of glazing material to emit light towards the second major surface of the first sheet of glazing material. The first and/or second major surface of the first sheet of glazing material has an array of dots thereon for diffusing light emitted by the illumination device that is transmitted through the first sheet of glazing material and out from the first major surface thereof.

Abstract: A laminated glazing is described comprising a first pane of glazing material having a first major surface and an opposing second major surface, there being an obscuration band on the second major surface extending around a portion of the periphery of the first pane such that the second major surface is not smooth. A first adhesive layer having a thickness of between 6 μm and 100 μm contacts a portion of the second major surface of the first pane of glazing material and a portion of the obscuration band. The laminated glazing also has a carrier ply carrying an infra red reflecting coating wherein the first adhesive layer is between the first pane of glazing material and the carrier ply.
