  • Patent number: 9658478
    Abstract: A laminated glazing with variable liquid-crystal-induced scattering, includes a first glass sheet; a first interlayer film for laminating the first glass sheet, made from a first plastic material; an electrically controllable, variable scattering system including the liquid crystals between a first support for a first electrode and a second support for a second electrode, the electrodes making contact with the liquid crystals; a second interlayer film, made from a second plastic material for laminating a second glass sheet; links to the electrodes; electrical wiring with two wiring inputs; a polymer material, for protecting the wiring inputs, which makes contact with the glass sheets; and a seal for sealing the liquid crystals and the electrodes from water. The protective polymer material forms a seal for sealing the electrode links and the wiring inputs from liquid water.
