Claim Text:
1. A capacitive touch panel, comprising: a first electrode layer comprising a plurality of first sensing electrode series linearly arranged along a first direction and disconnected from each other, wherein each of the first sensing electrode series comprises a plurality of first sensing electrodes, one portion of the adjacent first sensing electrodes are spaced by a first wide pitch, another portion of the adjacent first sensing electrodes are spaced by a first narrow pitch, and the first wide pitch is longer than the first narrow pitch; a second electrode layer comprising a plurality of second sensing electrode series linearly arranged along a second direction and disconnected from each other, wherein the first direction is orthogonal to the second direction; an insulating layer for electrically insulating the first electrode layer from the second electrode layer; and a single integrated circuit chip comprising a plurality of driving pins and a plurality of receiving pins, wherein the driving pins are connected to the first sensing electrode series respectively, and the receiving pins are connected to the second sensing electrode series respectively for detecting a capacitance variation, wherein the first wide pitch and the first narrow pitch are along the second direction, the first wide pitch is longer than a value of dividing a sensing length of the capacitive touch panel in the second direction to a number of the driving pins, the first narrow pitch is shorter than a value of dividing the sensing length of the capacitive touch panel in the second direction to the number of the driving pins.
