A method of manufacturing a digitizer includes the steps of ,applying a first conductive strip 305 (e.g. a copper busbar) along a first direction (e.g. Y) of an insulating substrate 303 (e.g. cardboard in the case of an opaque digitizer or whiteboard type or Polyvinyl Butyral PVB or Ethylene-Vinyl Acetate EVA sheet for a clear digitizer); arranging conductors 301 (e.g. tungsten, copper or aluminum wires) over the insulating substrate that extend along a second direction (e.g. X) and electrically connect at one end to the first conductive strip; applying a second conductive strip (305, fig 62b) to the insulating substrate along the second direction (e.g. X); arranging conductors (302, fig 62 b) over the insulating substrate that extend in the first direction (e.g. Y) and electronically connects at one end the second substrate; and cutting, etching or otherwise breaking the first and second conductive strips to form separate conductive pads (315, fig 64) to allow connection of the conductors to electronics of the digitiser. The first and second conductors may be on opposite sides of the substrate. The conductors may form a wiggle pattern to reduce the production of moiré patterns. Alternatively a second substrate may be used. A PVB sheet version may be sandwiched between two glass sheets. A number of different designs of digitiser are also disclosed. |
