Definitions
- the invention relates to a glazing, that is to say a panel at least partly transparent, which comprises several active zones whose properties can be modified independently of each other: transparent, translucent or opaque, of different colors, emitting light or not, supporting patterns or designs as printed, distinctive of a specific area, for locating a functionality or of a tactile command of a functionality for a specific area.
- This glazing could be useful both for the building and for a land, air or water vehicle, in particular a motor vehicle. We are particularly aiming at an automobile roof.
- interlayer adhesive for laminated glazing polyvinyl butyral (PVB), thermoplastic polyurethane (TPU), ethylene-acetate copolymer vinyl (EVA), or organic glass (structural transparent) of the poly(methyl methacrylate) type
- PMMA polycarbonate
- PET poly(ethylene terephthalate)
- PU polyurethane
- the invention has been produced, the subject of which is at least partially transparent glazing, the main surface of which is divided according to at least two perpendicular directions into partial surfaces capable of being concealed, opacified, colored and/or illuminated. independently of each other, in whole, in part and/or according to patterns, characterized in that the partial surfaces are associated with invisible touch controls identified by means of imprints. [0004] there is at least one straight line in each of said at least two perpendicular directions, which separates at least two said partial surfaces (at least almost all of them).
- an identification pattern is associated with at least one of the partial surfaces.
- a remote identification pattern and identification of invisible remote touch controls for a functionality of said at least one of the partial surfaces with which (with which) an identification pattern is associated, is also associated with said at least one of the partial surfaces.
- the remote identification pattern recalls the identification pattern of the zone; it looks like it, conforms to it, possibly constitutes its transformation by homothety, reduction of dimensions for example, and symmetry, so that the user understands that the touch control is that of a functionality for the corresponding zone (partial surface) .
- the glazing is monolithic in mineral glass such as soda-lime float, aluminosilicate, borosilicate, optionally hardened or tempered thermally or chemically reinforced, or in organic glass, that is to say in transparent structural polymer material : poly(methyl methacrylate) (PMMA), polycarbonate (PC), poly(ethylene terephthalate) (PET), polyurethane (PU).
- mineral glass such as soda-lime float, aluminosilicate, borosilicate, optionally hardened or tempered thermally or chemically reinforced, or in organic glass, that is to say in transparent structural polymer material : poly(methyl methacrylate) (PMMA), polycarbonate (PC), poly(ethylene terephthalate) (PET), polyurethane (PU).
- PMMA poly(methyl methacrylate)
- PC polycarbonate
- PET poly(ethylene terephthalate)
- PU polyurethane
- the glazing is laminated, that is to say made up of several sheets of glass bonded two by two consecutively by an intermediate adhesive layer: polyvinyl butyral (PVB), thermoplastic polyurethane (TPU), ethylene copolymer - vinyl acetate (EVA).
- PVB polyvinyl butyral
- TPU thermoplastic polyurethane
- EVA ethylene copolymer - vinyl acetate
- the partial surfaces comprise functional films based on liquid crystals encapsulated, or dispersed in a polymer matrix (abbreviation in English PDLC), of electrophoretic particles dispersed in a medium, of particles dispersed in an electrophoretic fluid or comprising a suspended particle device (SPD) film or a laminate of such a film, or an electrochromic system, or a diffusing enamel capable of extracting light from a light-emitting diode (abbreviation in English LED) positioned on the edge of the glazing.
- PDLCs functional films based on liquid crystals dispersed in a polymer matrix are known by the abbreviated acronym PDLCs.
- Liquid crystals dispersed in a polymer matrix are a class of heterogeneous materials consisting of a dispersion of liquid crystal microdroplets in a solid and more or less flexible polymer matrix. These materials have electro-optical properties, they can in fact switch between a highly diffuse opaque state if (OFF state) and a transparent state (ON state) after application of an electric field.
- the PDLC system is implemented in switchable windows. It has several advantages such as ease of manufacture, ease of use on a large scale, stability, speed of their response time and the fact of not requiring the use of polarizers which absorb almost half of the light. incident.
- mesophases can be used to produce these materials: the nematic phase, the cholesteric phase as well as the smectic A and
- the principle of electro-optical systems using a PDLC consists of a composite sandwiched between two electrodes made up of glass plates, one side of which is covered with a conductive and transparent layer of indium and tin oxide. (ITO). In the absence of an electric field, the mean orientation of liquid crystal molecular directors is random. The difference in refractive index between the segregated liquid crystal and the macromolecular matrix leads to a milky and opaque material which will scatter light (OFF state).
- ITO indium and tin oxide
- the molecular directors When an electric field is applied between the electrodes of the cell, the molecular directors are oriented in the direction of the field.
- a normal index beam passes through the droplets with a refractive index equal to n0, the ordinary index of liquid crystal molecules. If this index is close to that of the polymer matrix, the film appears clear and transparent (ON state).
- n0 the refractive index of liquid crystal molecules. If this index is close to that of the polymer matrix, the film appears clear and transparent (ON state).
- these particles may themselves contain a liquid and be dispersed in a suspension fluid.
- the suspension fluid may have a density or a refractive index whose values are substantially adapted to those which characterize the particles dispersed in the fluid.

- switchable glazing Compared to standard laminated glazing, electrically switchable glazing provides special additional functions which translate into terms of user comfort, light transmission and energy savings. Switchable glazing can rarely be installed directly as a finished product. Typically, prior to the implementation of switchable glazing, pre-lamination is required. For example, for the implementation of an SPD film at the level of the frame of the sunroof of a motor vehicle, it is necessary to produce a laminate between at least 2 sheets of clear glass or tinted with PVB. This is to meet safety standards in the event of glass breakage and extend the life of the SPD film.
