Abstract:
1. A method for detecting touch spot of a touch panel, the touch panel comprising: a substrate; a conductive film disposed on the substrate, wherein the conductive film is impedance anisotropic and defines a low impedance direction and a high impedance direction substantially perpendicular to the low impedance direction, the conductive film has a first side and a second side opposite to the first side, a direction from the first side to the second side is the low impedance direction; a plurality of first driving-sensing electrodes arranged along the first side and spaced from each other; a plurality of second driving-sensing electrodes arranged along the second side and spaced from each other; wherein the plurality of first driving-sensing electrodes and the plurality of second driving-sensing electrodes are electrically connected with the conductive film, each of the plurality of first driving-sensing electrodes and the plurality of second driving-sensing electrodes is electrically connected with a driving circuit and a sensing circuit, when the touch panel is touched by a conductive object at a touch spot, a coupling capacitance having a capacitance value C between the conductive film and the conductive object is formed, a resistance of the conductive film between a touch spot and each of the plurality of first driving-sensing electrodes is represented by R the method comprising:
