A touch panel and sensing method thereof include a first sensing pad group, a second sensing pad group and a first selection module. The first selection module includes a first selection terminal, a first input terminal, a first output terminal and a second output terminal. At a first time period, a first control signal is provided to the first selection terminal to conduct the first sensing pad group and a first driving signal terminal, and first sensing data of the first sensing pad group is determined. At a second time period, the first control signal is provided to the first selection terminal to conduct the second sensing pad group, and a first driving signal terminal and second sensing data is determined.
