ABSTRACT:
A method for managing power consumption of a digitizing panel includes the steps of: (a) applying a biasing voltage to the digitizing panel for a first period of time and ceasing to apply the biasing voltage to the digitizing panel for a second period of time; (b) determining whether a user has touched the digitizing panel during the first period of time; and (c) if the user has touched the digitizing panel during the first period of time, then applying a biasing voltage to the digitizing panel for a third period of time that is longer in duration than the first period of time and ceasing to apply the biasing voltage to the digitizing panel for a fourth period of time. An apparatus for implementing the method is also disclosed.
