1. A method of operating a sensing circuit, the sensing circuit comprising a plurality of sensing units and a plurality of sensing electrodes, the sensing electrodes being divided into a first group and a second group, the method comprising:
providing a first sensing signal to the sensing electrodes of the first group in a first time period, wherein the sensing electrodes of the first group are electrically connected to a portion of the sensing units; and
providing a second sensing signal to the sensing electrodes of the second group in a second time period, wherein the sensing electrodes of the second group are electrically connected to another portion of the sensing units;
wherein the first time period and the second time period starts at different times and are not overlapped with each other; and
wherein the sensing units are arranged in M rows and N columns, M and N are integers greater than 1.
