Abstract

A touch panel is disclosed. The touch panel comprises a driving electrode including a plurality of driving electrode-cells and a sensing electrode including a plurality of sensing electrode-cells. The driving electrode and the sensing electrode are formed in the same layer of the touch panel. Each of the sensing electrode-cells is configured to envelop up-down-left-right side of a driving electrode-cell which is electrically coupled to the each of the sensing electrode-cells. And a slit is formed at each of the sensing electrode-cells for connecting a driving trace to the driving electrode-cell.
