Claim Text:
1. A touch panel comprising: a substrate having a first side and a second side opposite to the first side; a plurality of first electrodes disposed on the first side of the substrate and a plurality of second electrodes disposed on the second side of the substrate; wherein an inside lateral and an outside lateral of the substrate together defines a touch area; and wherein an opening without the first electrodes and the second electrodes distributed thereon is formed in the touch area, and a plurality of first initial positions and a plurality of first termination positions are located on two opposite sides of the opening; wherein the first electrodes extend along a first initial direction from the plurality of first initial positions, and divert from the first initial direction to terminate in the plurality of first termination positions; wherein the first electrodes extend from the first initial position to the first termination position by taking the essence center of the substrate as the center of the circle such that the first electrodes are formed with a plurality of concentric-circle patterns; and the plurality of second electrodes extending along a second initial direction from a plurality of second initial positions to terminate in a plurality of second termination positions; wherein the second initial positions are located on the inside lateral of the substrate, and the second termination positions are located on the outside lateral of the substrate; and wherein the second electrodes extend from the second initial position to the second termination position to form a plurality of polar sector patterns.
