Abstract
An improved tablet for a digitizer including a stylus and a tablet for digitizi An 5 Vt pV:stylus position on the tablet as a function of the stylus current distribution over the tablet includes a first resistive coating on the face of the tablet for conducting stylus current to a plurality of current sensors about the periphery of the tablet; and one or more additional resistive coatings covering the first resistive coating and connected electrically in parallel with the first resistive coating for providing an additional wearing layer to protect and prolong the life of the first reactive coating, the additional resistive coatings having resistance values higher than the first resistive coating.
