摘要： A positioning method and a driving apparatus of a touch panel are provided. The touch panel includes a conductive layer with anisotropic conductivity, a plurality of first electrodes and a plurality of second electrodes. The first electrodes and the second electrodes are respectively disposed on a first side and a second side of the conductive layer. The first electrodes and the second electrodes are sensed to obtain a plurality of sensing values. A first relative extreme portion at least having a relative extreme is defined among the first electrodes. A second relative extreme portion at least having a relative extreme is defined among the second electrodes. A ratio of sensing values is calculated according to the first relative extreme portion and the second relative extreme portion. A position of a touch point on the touch panel in a first axial direction is calculated with the ratio of sensing values.
