1. A laminated glazing comprising:
a first glass substrate and a second glass substrate laminated together having first and second polymer intermediate films therebetween; and
a layered film laminated between the first and second polymer intermediate films, wherein the layered film comprises:
at least three carrier films positioned in parallel to one another with a second carrier film positioned between first and third carrier films, wherein a first surface of the first carrier film is coated with a first transparent conductive coating and a first surface of the second carrier film is coated with a second transparent conductive coating, wherein the first surface of the first carrier film faces the first surface of the second carrier film, and
wherein a second surface of the second earner film is coated with a third transparent conductive coating and a first surface of the third carrier film is coated with a fourth transparent conductive coating, wherein the second surface of the second carrier film faces the first surface of the third carrier film;
a first switchable layer positioned between the first and second carrier films; and
a second switchable layer positioned between the second and third carrier films,
wherein the first carrier film comprises a first polarizing film and the second carrier film comprises a second polarizing film, wherein the first polarizing film comprises a polarizing angle 90° to a polarizing angle of the second polarizing film,
wherein the third carrier film comprises a non-polarizing carrier film, and
wherein the first switchable layer comprises a liquid crystal layer.
