Abstract
A capacitive touch panel includes a substrate; a transparent conductive layer with anisotropic impedance located on the substrate; a plurality of driving sensing electrodes located on the opposite two sides of the transparent conductive layer; at least one sensing unit connected to the plurality of driving sensing electrodes for scanning the plurality of driving sensing electrodes; at least one voltage compensation unit which provides a offset voltage, at least one voltage compensation unit has a first end and a second end, the first end of at least one voltage compensation unit is at least connected to one of the plurality of driving sensing electrodes, the second end of at least one voltage compensation unit is connected to a grounding voltage. The present application also relates to a driving method for preventing leakage current of the capacitive touch panel.
