Process for manufacturing a laminated glazing (100, 200, 210, 300, 310, 400, 500, 600, 700, 800, 900, 910) with liquid-crystal-induced variable scattering, in which: - a structure is provided comprising: - a first glass sheet; - a first lamination interlayer made from a first thermoplastic material; - an electrically controllable, variable scattering system comprising the liquid crystals between a first support of a first electrode and a second support of a second electrode, the first and second electrodes making contact with the liquid crystals; - a second lamination interlayer made from a second thermoplastic material, especially of the first type; - a second glass sheet; - electricity supply wiring with a first wiring input connected to a first link of the first electrode and a second wiring input connected to a second link of the second electrode; and - a means for sealing the first and second electrode links and the first and second wiring inputs from liquid water, even water vapour, is formed by the following steps: - a protective thermoplastic polymer material is inserted into a mould having what is called an internal moulding surface facing the first and second wiring inputs; - the assembly is placed in a sealed vacuum system, the protective thermoplastic polymer material is heated until fluid so that the protective thermoplastic polymer material follows closely the moulding surface and makes contact with the first and second glass sheets, said heating furthermore fluidizing the first and second thermoplastic materials so as to ensure the lamination during the same heat treatment, the protective thermoplastic polymer material making contact with the first and second thermoplastic materials and thus forming with the first and second thermoplastic materials a continuous length of material(s). - a structure is provided comprising: - a first glass sheet; - a first lamination interlayer made from a first thermoplastic material; - an electrically controllable, variable scattering system comprising the liquid crystals between a first support of a first electrode and a second support of a second electrode, the first and second electrodes making contact with the liquid crystals; - a second lamination interlayer made from a second thermoplastic material, especially of the first type; - a second glass sheet; - electricity supply wiring with a first wiring input connected to a first link of the first electrode and a second wiring input connected to a second link of the second electrode; and - a first glass sheet; - a first lamination interlayer made from a first thermoplastic material; - an electrically controllable, variable scattering system comprising the liquid crystals between a first support of a first electrode and a second support of a second electrode, the first and second electrodes making contact with the liquid crystals; - a second lamination interlayer made from a second thermoplastic material, especially of the first type; - a second glass sheet; - electricity supply wiring with a first wiring input connected to a first link of the first electrode and a second wiring input connected to a second link of the second electrode; and - a means for sealing the first and second electrode links and the first and second wiring inputs from liquid water, even water vapour, is formed by the following steps: - a protective thermoplastic polymer material is inserted into a mould having what is called an internal moulding surface facing the first and second wiring inputs; - the assembly is placed in a sealed vacuum system, the protective thermoplastic polymer material is heated until fluid so that the protective thermoplastic polymer material follows closely the moulding surface and makes contact with the first and second glass sheets, said heating furthermore fluidizing the first and second thermoplastic materials so as to ensure the lamination during the same heat treatment, the protective thermoplastic polymer material making contact with the first and second thermoplastic materials and thus forming with the first and second thermoplastic materials a continuous length of material(s). - a protective thermoplastic polymer material is inserted into a mould having what is called an internal moulding surface facing the first and second wiring inputs; - the assembly is placed in a sealed vacuum system, the protective thermoplastic polymer material is heated until fluid so that the protective thermoplastic polymer material follows closely the moulding surface and makes contact with the first and second glass sheets, said heating furthermore fluidizing the first and second thermoplastic materials so as to ensure the lamination during the same heat treatment, the protective thermoplastic polymer material making contact with the first and second thermoplastic materials and thus forming with the first and second thermoplastic materials a continuous length of material(s).
