Abstract: A positioning method and a driving apparatus for a touch panel having a plurality of sense electrodes in an axis direction are disclosed. The driving apparatus detects the sense electrodes to obtain a plurality of sensed values. The driving apparatus counts the number of multiple candidate electrodes, wherein the candidate electrode is an electrode having a sensed value larger than a first threshold value. The first threshold value is increased and the number of the candidate electrodes is counted again if the number of the candidate electrodes is larger than a second threshold value. At least one electrode is selected as a positioning electrode from the candidate electrodes if the number of the candidate electrode is not larger than the second threshold value. A position of a touch point on the touch panel in the axis direction is calculated based on the position and sensed value of the positioning electrode.
