摘要：
A method for determining touch position of a touch panel, which includes reading a voltage signal of a first sensing unit through a readout line in a first time slot of a frame period; reading a voltage signal of a second sensing unit through the readout line in a second time slot of the frame period; generating a difference by subtracting the voltage signal of the second sensing unit from the voltage signal of the first sensing unit, and determining whether the first sensing unit and the second sensing unit are touched according to the difference.
