A method of detecting pressure on a touch sensing element includes providing a first potential difference to two electrodes of a first film, charging a capacitor with a division voltage of the first potential difference, sampling a charged voltage of the capacitor to obtain a plurality of first voltage values and calculating a first voltage variation according to the plurality of first voltage values, comparing the first voltage variation with a threshold value, and post-processing at least one of the first voltage values when the first voltage variation is smaller than the threshold value. |
