Abstract:
1. A positioning method of a touch panel, wherein the touch panel comprises a conductive layer with anisotropic conductivity and a plurality of electrode pairs, each of the electrode pairs comprises a first electrode and a second electrode, two opposite sides of the conductive layer along a first axial direction are respectively a first side and a second side, the first electrodes are disposed on the first side of the conductive layer, and the second electrodes are disposed on the second side of the conductive layer, the positioning method comprising: sensing the first electrodes and the second electrodes to obtain a plurality of sensing values; defining a first relative extreme portion among the sensing values of the first electrodes, wherein the first relative extreme portion having at least one first relative extreme in the sensing values of the first electrodes; defining a second relative extreme portion among the sensing values of the second electrodes, wherein the second relative extreme portion having at least one second relative extreme in the sensing values of the second electrodes; calculating a ratio of sensing values according to the first relative extreme portion and the second relative extreme portion; and calculating a position of a touch point on the touch panel in the first axial direction by the ratio of sensing values.
