Claim 22:
23. A touch sensor or fingerprint sensor comprising:
a conductor assembly, comprising:
a transparent substrate defining perpendicular directions X and Y in a plane of said substrate,
a plurality of conducting tracks of a non-transparent material positioned on said substrate, wherein at least some of said tracks are members of a first set of tracks and are parallel to each other along said direction X,
wherein the tracks have a width of less than 10 μm, and
wherein, for each of said tracks, and along both said directions X and Y, a distance between said track and a next one of said tracks is less than 200 μm,
wherein some of said tracks are members of a second set of tracks,
wherein the tracks of said second set of tracks are parallel to each other,
wherein said first and second sets of tracks intersect and form individually addressable sensing regions,
and wherein said first and said second set of tracks extend perpendicularly to each other, and/or wherein a distance between neighboring tracks of said second set is equal to the distance between neighboring tracks of said first set, and

said touch sensor further comprising:
a controller having transmission outputs and sensing inputs, wherein at least part of said first set of tracks is connected to said transmission outputs and at least part of said second set of tracks is connected to said sensing inputs,
wherein said touch sensor comprises a plurality of individually addressable sensing regions formed by the intersections of transmission and sensing bands,
wherein each transmission band comprises at least one unbroken track of said first set of tracks extending all over the touch sensor and each sensing band comprises at least one unbroken track of said second set of tracks extending all over the touch sensor,
wherein at least one of said bands and/or all of said sensing bands, comprise at least two tracks extending all over said touch sensor,
wherein, in at least one of said sets of tracks, some of the tracks are interrupted at locations where they intersect the tracks of the other set of tracks, and
wherein an added distance between the ends of said interrupted tracks and the closest track of the other set is equal to the distance between neighboring interrupted tracks.
