摘要： A method for detecting a touch spot of the touch panel includes the following steps. The electrode pairs are scanned along the impedance direction for determining a first coordinate. A number of electrode pairs near the first coordinate are selected to obtain an electrode pair signal. The first driving electrodes of the selected electrode pairs are scanned to obtain a first signal. The second driving electrodes of the selected electrode pairs are scanned to obtain a second signal. A second coordinate is determined according to the electrode pair signal, first signal, and second signal. Finally, the touch spot is determined according to the first coordinate, and second coordinate.
