Abstract: A mutual capacitance touch screen to cause dispersed coupling of electrodes includes driving electrode chains, sensing electrode chains and a data processing module. The central line of any driving electrode chain and the central line of any sensing electrode chain are mutually vertical. The driving electrode chains comprise at least two driving electrode plates. Two adjacent driving electrode plates are electrically connected by means of driving electrode connecting strips made of the conductive material. Thus, two clearances are formed between two adjacent driving electrode plates. Bar-shaped concave clearances which are recessed towards the driving electrode plates are also arranged on the driving electrode plates. The sensing electrode chains are arranged to fill the gaps and the concave clearances among the driving electrode chains in the touch screen. In the utility model, the coupling electric field is dispersed.
