1. A method for identifying a sensing value of a touch panel, comprising:

  • sensing a plurality of electrodes of the touch panel to obtain raw data and baseline data of each electrode, wherein an electrode Si denotes an ith electrode of the electrodes of the touch panel;

    calculating a sensing value of the electrode Si in accordance with the raw data and the baseline data of the electrode Si;

    when sensing values of all the electrodes Si are smaller than a threshold value, updating the baseline data of the electrode Si in accordance with the raw data of the electrode Si; and

    when a sensing value of any one electrode Si of the electrodes is larger than the threshold value, suspending updating the baseline data of the electrodes.
