Abstract
A touch-sensitive input device (2) is described. The device comprises an opaque substrate (11) having first and second opposite faces (12, 13), a first set of electrodes (14) disposed on the first face of the substrate, the electrodes generally extending in a first direction and spaced apart along a second, transverse direction, and a second set of electrodes (17) disposed on the first or second face of the substrate, the electrodes generally extending in the second direction and spaced apart along the first direction, wherein the first and second sets of electrodes overlap.
