A touch panel and a sensing method thereof are provided. The sensing method includes: sensing a touch operation on a touch panel, and getting a touch trajectory of the touch operation. When the touch operation is occurred in a first sensing area, positions of the touch operation are co-located by first sensing electrodes and second sensing electrodes of the first sensing area. When the touch operation is occurred in a second sensing area, positions of the touch operation are co-located by third sensing electrodes and fourth sensing electrodes of the second sensing area. When the touch operation is occurred between the first sensing area and the second sensing area, positions of the touch operation are co-located by the first sensing electrodes and the third sensing electrodes.
