Abstract: A single-layer mutual capacitive touch screen includes a substrate; a control circuit, disposed at a side of the substrate; a plurality of touch sensing electrodes, arranged on the substrate in an N×M array and classified into a first group and a second group; a plurality of output pins, for connecting the control circuit to the plurality of touch sensing electrodes; and a plurality of driving wires, each connecting a touch sensing electrode and an output pin. In the first group, each touch sensing electrode located at odd columns of the N×M array substantially shares an output pin with an adjacent touch sensing electrode located in a first direction of the touch sensing electrode. In the second group, each touch sensing electrode located at even columns of the N×M array substantially shares an output pin with an adjacent touch sensing electrode located in the first direction of the touch sensing electrode.
