GLAZING WITH ACTIVE AREAS THE CONTROLS OF WHICH ARE IDENTIFIED BY SIGNS PRODUCED USING DIGITAL PRINTING
A glazing, at least partially transparent, the main surface of which is divided into partial surfaces capable of being concealed, opacified, colored and/or illuminated independently of each other, in whole, in part and/or in accordance with designs, the partial surfaces being associated with invisible touch controls identified by prints, an identification design on the one hand, an offset design for identification and tracking of invisible offset touch controls on the other hand, being associated with at least one of the partial surfaces.
1 . A glazing at least partially transparent comprising a main surface which is divided along 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 conforming to designs, wherein the partial surfaces are associated with invisible touch controls identified by means of prints.
2 . The glazing according to claim 1 , wherein an identification design is associated with at least one of the partial surfaces.
3 . The glazing according to claim 2 , wherein an offset design for identification and tracking of remote touch controls that are invisible, for a functionality of said at least one of the partial surfaces with which an identification design is associated, is also associated with said at least one of the partial surfaces.
4 . The glazing according to claim 1 , wherein the glazing is monolithic in mineral or organic glass.
5 . The glazing according to claim 1 , wherein the glazing is laminated.
6 . The glazing according to claim 1 , wherein the partial surfaces comprise functional films based on liquid crystals encapsulated, or dispersed in a polymer matrix (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 scattering enamel capable of extracting the light from a light-emitting diode (LED) positioned on the edge of the glazing.
7 . A method for producing a glazing according to claim 3 , comprising producing said identification designs and said offset identification designs using digital printing, and producing said prints using screen printing, or conversely producing said identification designs and said offset identification designs using screen printing and producing said prints using digital printing, or else said identification designs, said offset identification designs and said prints are all produced using digital printing.
8 . The method according to claim 7 , wherein the glazing is a laminated glazing with two sheets of mineral or organic glass bonded by an adhesive interlayer, wherein faces of the two sheets of glass are conventionally numbered from 1 for the face intended to be in contact with an external space to 4 for the face intended to be in contact with an internal volume, and wherein each digital print is produced on one of the faces 2, 3 or 4 thus defined, and each screen print is produced on glass or on an interlayer.
9 . The method according to claim 8 , wherein the identification designs and the offset identification designs are produced using digital printing on face 3 and the prints are produced using screen printing on glass on face 4.
10 . The method according to claim 7 , wherein at least one of the identification designs, of the offset identification designs and prints is made of a digital printing ink or a scattering screen printing enamel, so that light-emitting diodes (LEDs) lit and positioned on the edge of the glazing make the at least one of the identification designs, of the offset identification designs luminous, and wherein the at least one of the identification designs, of the offset identification designs and prints remain(s) visible when the LEDs are off.
11 . The method according to claim 8 , wherein the invisible touch controls and offset touch controls consist of a conductive film that is laminated between two interlayer adhesive sheets, one of which has a thickness at most equal to 0.2 and in direct contact with a face of the opposite sheet of glass to that whereupon the touch functionality is exercised.
12 . A method comprising providing a glazing according to claim 1 as a glazing for a building, or for a land, airborne or water vehicle.
13 . The method according to claim 12 , wherein the glazing is an automotive vehicle roof.
14 . The method according to claim 11 , wherein the thickness is at most 0.1 mm.
