1. An optically transparent 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 um,
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; and
wherein, in a sectional view extending perpendicularly to a longitudinal direction of each track, a surface of the tracks facing away from said substrate is rounded, and wherein a largest curvature of over at least 50% of said surface is no more than the width of said track.
