Claim:
1. A touch input device comprising at least one first electrode structural unit formed on a first surface of a substrate, the first electrode structural unit comprising: a first column of driving electrodes comprising at least one first driving electrode; a sensing electrode extending in a column direction; and a second column of driving electrodes comprising at least one first driving electrode, and at least one second electrode structural unit formed on the first surface of the substrate, the second electrode structural unit being identical with the first electrode structural unit except that in the second electrode structural unit the driving signal leads to which the first column of driving electrodes is connected and the ones to which the second column of driving electrodes is connected are interchanged, wherein the first column of driving electrodes, the sensing electrode and the second column of driving electrodes are arranged successively in a row direction, wherein each of the first driving electrodes is connected to a different driving signal lead, and the sensing electrode is connected to a sensing signal lead, and wherein each of the first driving electrodes and a corresponding portion of the sensing electrode form a capacitor, and wherein the at least one first electrode structural unit and the at least one second electrode structural unit are arranged alternately in the row direction to form an electrode array, the driving electrodes located at corresponding positions in respective first electrode structural units are connected to the same driving signal, the driving electrodes located at corresponding positions in respective second electrode structural units are connected to the same driving signal, and the sensing electrodes in respective first electrode structural units and respective second electrode structural units are connected to respective different sensing signals.
