1. A touch sensitive device, comprising:

  • a capacitive touch panel comprising plural electrodes;

    a driving and sensing circuit electrically connected to the electrodes of the capacitive touch panel through plural sensing lines; and

    at least one conductive member arranged to cross over the sensing lines without contact with any of the sensing lines, and electrically connected to the driving and sensing circuit,wherein the driving and sensing circuit outputs a driving signal to the capacitive touch panel through the at least one conductive member, and receiving sensing signals through the sensing lines, so as to generate a coupling effect between the at least one conductive member and the sensing lines for detecting a touch-sensing action at the capacitive touch panel.
