ABSTRACT:
A flexible circuit (28) containing the grid connectors of a digitizer tablet (10) converge in a transition region (48) disposed in an unshielded area. However, the positional inaccuracies that would otherwise result from the exposure of the non-parallel conductors to radiation from the tablet's stylus (24) are reduced because the flexible circuit (28) is kept in close proximity to a metal plate (32) throughout the transition region (48) in which the conductors depart from a parallel configuration.
