Touch spot detecting method of touch panel

A detecting method for detecting at least one touch spot of a touch panel, wherein the touch panel includes a conductive film, a plurality of first electrodes and a plurality of second electrodes, the conductive film having anisotropic impedance so as to define a high impedance direction (X direction) and a low impedance direction (Y direction), and the conductive film having a first side and a second side which are located at two opposite sides of the low impedance direction, the first electrodes and the second electrodes are located along the first side and the second side, respectively, and electrically connected to the conductive film, the detecting method comprising the steps of:

• obtaining a plurality of actual detecting signals detected from the first electrodes and the second electrodes;
• determining two of the first electrodes and two of the second electrodes closest to the touch spot;
• defining a corrective area located between the two first electrodes and the two second electrodes;
• setting an ideal resistance of the corrective area (Rideal);
• defining arbitrarily one electrode of the two first electrodes and the two second electrodes as an electrode (i);
• and
• correcting the actual sensing signal (Si) of the electrode (i) in accordance with a ratio of the ideal resistance and an actual resistance of the untouched corrective area.
