Abstract

A laminated glass pane having a first glass layer and a second glass layer, wherein at least one first electrically conducting structure and a second electrically conducting structure are arranged between the first glass layer and the second glass layer, wherein the first electrically conducting structure and the second electrically conducting structure are arranged spaced apart from one another, wherein the first electrically conducting structure at least partially overlaps the second electrically conducting structure in a perpendicular orientation relative to the first glass layer, wherein the first electrically conducting structure is associated with a first electrical element, wherein the first electrical element is a capacitive sensor.

First claim

The invention claimed is:

1. Laminated glass pane having a first glass layer and a second glass layer, wherein at least one first electrically conducting structure and a second electrically conducting structure are arranged between the first glass layer and the second glass layer, wherein the first electrically conducting structure and the second electrically conducting structure are arranged spaced apart from one another along a direction perpendicular to a main surface of the first glass layer, with the first electrically conducting structure being arranged in a first plane and the second electrically conducting structure being arranged in a second plane different from the first plane, wherein the first electrically conducting structure at least partially overlaps the second electrically conducting structure in a perpendicular orientation relative to the first glass layer, wherein the first electrically conducting structure constitutes a first electrical element and the second electrically conducting structure constitutes a second electrical element, wherein the first electrical element and the second electrical element are each a capacitive sensor, wherein one of the first electrically conducting structure and the second electrically conducting structure provides a ground potential and the other one of the first electrically conducting structure and the second electrically conducting structure provides a different potential to be measured, and wherein the first electrically conducting structure and the second electrically conducting structure are arranged on at least one inlet, with the first electrically conducting structure being arranged on one side of the inlet and the second electrically conducting structure being arranged on an opposite side of the inlet.

2. The laminated glass pane according to claim 1 , wherein the first electrical element is a touch sensor or a proximity sensor, and the second electrical element is a rain sensor.

3. The laminated glass pane according to claim 1 , wherein the laminated glass pane has a black print at least partially at a location of the first electrically conducting structure.

4. The laminated glass pane according to claim 1 , wherein the laminated glass pane further has at least one combination film between the first glass layer and the second glass layer, wherein the at least one combination film contains at least one material selected from the group consisting of polybutylene terephthalate (PBT), polycarbonate (PC), polyethylene terephthalate (PET) and polyethylene naphthalate (PEN), polyvinyl chloride (PVC), polyvinyl fluorides (PVF), polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polyacrylate (PA), polymethyl methacrylate (PMMA), polyurethane (PUR), and/or mixtures and copolymers thereof.

5. The laminated glass pane according to claim 1 , wherein the laminated glass pane further has an electrical connection to the first electrically conducting structure and/or the second electrically conducting structure, wherein the electrical connection is arranged through one of the first and second glass layers or at the edge of the first and second glass layers.

6. The laminated glass pane according to claim 1 , wherein the first electrically conducting structure and the second electrically conducting structure are arranged on at least one inlet, wherein the at least one inlet has polyethylene terephthalate.

7. The laminated glass pane according to claim 1 , wherein the inlet has a folded film.

8. The laminated glass pane according to claim 1 , wherein the first electrically conducting structure is arranged on the first glass layer and the second electrically conducting structure is arranged on the second glass layer.

9. A method comprising utilizing a laminated glass pane according to claim 1 in a vehicle or a building or in an information display.

10. Method for producing a laminated glass pane according to claim 1 , comprising:
obtaining a first glass layer and a second glass layer,
obtaining a first inlet film having a first electrically conducting structure and a second inlet film having a second electrically conducting structure,
arranging the first inlet film relative to the first glass layer such that the first electrically conducting structure is closer to the first glass layer,
arranging the second inlet film relative to the first glass layer such that the second electrically conducting structure is closer to the second glass layer,
bonding the arranged first and second glass layers and the first and second inlet films under the influence of heat.

11. Method for producing a laminated glass pane according to claim 7 , comprising:
obtaining a first glass layer and a second glass layer,
obtaining an inlet film having a first electrically conducting structure and a second electrically conducting structure,
folding the inlet film such that the first electrically conducting structure and the second electrically conducting structure at least partially overlap one another,
arranging the inlet film relative to the first glass layer such that the first electrically conducting structure is closer to the first glass layer and the second electrically conducting structure is closer to the second glass layer,
bonding the arranged first and second glass layers and inlet film under the influence of heat.

12. Method for producing a laminated glass pane according to claim 8 , comprising:
obtaining a first glass layer and a second glass layer,
structuring a first electrically conducting structure on the first glass layer and a second electrically conducting structure on the second glass layer,
arranging the first glass layer such that the first electrically conducting structure is closer to the first glass layer and the second electrically conducting structure is closer to the second glass layer,
bonding the arranged first and second layers and the first and second electrically conducting structures under the influence of heat.

13. The method according to claim 10 , further comprising arranging at least one combination film between the first glass layer and the second glass layer, before the arranged first and second glass layers and first and second inlet films are bonded under the influence of heat.
