1. A touch display panel, comprising:
a plurality of first electrodes, arranged in an active area of the touch display panel, and configured to perform a touch sensing operation in a first period; and
at least one second electrode, arranged in a border area of the touch display panel, wherein the plurality of first electrodes and the at least one second electrode are configured to perform a gesture sensing operation in a second period,
wherein a specified signal is applied to the plurality of first electrodes and a synchrotron signal is applied to the at least one second electrode in a third period, wherein the synchrotron signal is a same as the specified signal, and the touch display panel is configured to perform a display operation in the third period,
wherein the touch sensing operation and the gesture sensing operation are not performed in the third period, and the first period, the second period and the third period are time-division multiplexing phases, and
wherein the plurality of first electrodes are configured as driving electrodes, and the at least one second electrode is configured as sensing electrodes in the second period.
