1. A touch panel module, comprising:
a touch panel, comprising one or more conductive electrodes and one or more dummy electrodes, wherein the one or more conductive electrodes comprise at least one of one or more driving electrodes and one or more sensing electrodes, and the one or more dummy electrodes are configured to fill areas between the one or more conductive electrodes or areas outside the one or more conductive electrodes; and
an electrostatic discharge protection circuit, electrically connected to at least one dummy electrode of the one or more dummy electrodes, and configured to provide an electrostatic discharging path to the at least one dummy electrode,
wherein the electrostatic discharge protection circuit discharges accumulated electrostatic charges of the at least one dummy electrode through the electrostatic discharging path at all times, or
the electrostatic discharge protection circuit discharges the accumulated electrostatic charges of the at least one dummy electrode through the electrostatic discharging path when a potential difference between two ends of the electrostatic discharge protection circuit is greater than a voltage threshold.
