摘要： A touch panel includes a conductive film having anisotropic impedance, a plurality of first electrodes, and a plurality of second electrodes. In a method for detecting a touch spot, a plurality of actual detecting signals are obtained by the first electrodes and the second electrodes, thereby determining two first electrodes and two second electrodes closest to the touch spot. The conductive film between the two first electrodes and two second electrodes is defined as a corrective area. An ideal resistance of the corrective area is set. An arbitrary electrode from the two first electrodes and two second electrodes is defined as electrode i. The actual detecting signal Si obtained by the electrode i is corrected according to a ratio of the ideal resistance to an actual resistance of the untouched corrective area.
