Capacitive touch screen with electrode chains arranged in folding way

The invention discloses a capacitive touch screen with electrode chains arranged in a folding way. The capacitive touch screen comprises a first electrode cluster and a second electrode cluster, wherein the electrode clusters comprise respective electrode chains; each electrode chain consists of plate electrodes which are connected in series; in the first electrode cluster, a first electrode group is formed in a way that each two neighboring first electrode chains are of a group; in the second electrode cluster, a second electrode group is formed in the way that each two neighboring second electrode chains are of a group; and the two electrode chains of each electrode group are both electrically connected to ports of a signal generating/processing module arranged outside of a touch screen so that each electrode group is electrically connected with the corresponding port of the signal generating/processing module respectively. In the capacitive touch screen, under the situation of maintaining the number of leading-out wires unchanged, the number of the electrode chains is doubled, and the space between the electrode chains are reduced, so that detection data volume and detection sensitivity of a touch action is improved; and simultaneously the effective permittivity of the touch screen is improved.
