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. ## Claims ### Claim 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, wherein the partial surfaces of the glazing comprise a first partial surface and a second partial surface, wherein the second partial surface is associated with a first invisible touch control for controlling concealment, opacification, coloration and/or illumination of the second partial surface, said first invisible touch control being (a) offset from said second partial surface and (b) located in said first partial surface, and a first offset identification print is provided on the glazing in said first partial surface to identify a location of said first offset invisible touch control and to allow actuation of said first offset invisible touch control to operate the second partial surface, and wherein said second partial surface comprises a second invisible touch control for also controlling concealment, opacification, coloration and/or illumination of the second partial surface and a second identification print to identify a location of said second invisible touch control. ### Claim 2 (depends on 1) The glazing according to claim 1, wherein the second partial surface further comprises an identification design comprising a printed marking that is different from that said second identification print. ### Claim 3 (depends on 1) The glazing according to claim 1, wherein the glazing is monolithic in mineral or organic glass. ### Claim 4 (depends on 1) The glazing according to claim 1, wherein the glazing is laminated. ### Claim 5 (depends on 1) 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. ### Claim 6 (depends on 2) The glazing according to claim 2, wherein the first offset identification print located in said first partial surface has a same graphical design as the identification design associated with the second partial surface, so that a user visually associates the first offset invisible touch control with the second partial surface. ### Claim 7 (depends on 6) The glazing according to claim 6, wherein the first offset identification print located in said first partial surface is a reproduction of the identification design located in said second partial surface by homothety with reduced dimensions relative to the identification design. ### Claim 8 (depends on 6) The glazing according to claim 6, wherein the first offset identification print located in said first partial surface is a symmetric reproduction of the identification design located in said second partial surface. ### Claim 9 (depends on 6) The glazing according to claim 6, wherein the first offset identification print located in said first partial surface conforms in outline to the identification design located in said second partial surface, thereby evoking the identification design of the second partial surface to indicate that the first offset invisible touch control operates the second partial surface. ### Claim 10 (depends on 6) The glazing according to claim 6, wherein the first offset identification print located in said first partial surface and the identification design located in said second partial surface are produced by digital printing on a glass face of the glazing, and the first offset identification print is disposed on an inner face of the glazing. ### Claim 11 (depends on 6) A method for producing a glazing according to claim 6, comprising producing said identification design located in said second partial surface and said first offset identification print located in said first partial surface using digital printing, or screen printing. ### Claim 12 (depends on 11) The method according to claim 11, 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. ### Claim 13 (depends on 12) The method according to claim 12, wherein the identification design is produced using digital printing on face 3 and the offset identification print is produced using screen printing on glass on face 4. ### Claim 14 (depends on 11) The method according to claim 11, wherein light-emitting diodes (LEDs) lit and positioned on the edge of the glazing make the identification design located in said second partial surface or the first offset identification print located in said first partial surface luminous, and wherein the identification design or the first offset identification print remains visible when the LEDs are off. ### Claim 15 (depends on 12) The method according to claim 12, wherein the first invisible touch control and first offset touch control 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. ### Claim 16 (depends on 1) A method comprising providing a glazing according to claim 1 as a glazing for a building, or for a land, airborne or water vehicle. ### Claim 17 (depends on 16) The method according to claim 16, wherein the glazing is an automotive vehicle roof. ### Claim 18 (depends on 15) The method according to claim 15, wherein the thickness is at most 0.1 mm.
