In a capacitive touch panel having touch cells arranged in a two-dimensional array and defined by two coordinates, the present invention provides a third coordinate. In particular, the touch cells in a row are electrically connected a first sensing element and the touch cells in a column are electrically connected in a second sensing element. The first sensing elements can be arranged into two or more touch zones. Each of the touch zones has a zone sensing element for defining the zone coordinate. Some of the first sensing elements in one touch zone are electrically connected to the corresponding first sensing elements in the other touch zones in series. As such, the number of terminals connected to the first sensing elements can be reduced.
