ABSTRACT:
A digitizing tablet for use in conjunction with a stylus and a digitizing circuit capable of generating signals representative of the position of the stylus on the digitizing tablet is disclosed. The digitizing tablet includes a sheet of glass that functions as the writing surface over which the stylus is disposed. On the underside of the glass, opposite the writing surface, there are lines of conductive ink that have been applied as two sets of parallel lines that intersect perpendicularly so as to form a grid. A dielectric ink is applied over the conductive ink to serve as a protective coating and an insulator to prevent current flow at the points the lines intersect. The lines of conductive ink terminate at surface contact pads also formed of conductive ink. Electrical components can be surface mounted to the digitizing tablet at the surface contact pads by the use of a solder, conductive adhesive or other conductive bonding media.
