Touch substrate, touch screen and electronic device having electro-static discharge protective capability

A touch substrate comprising:

• a base substrate comprising a first surface and a second surface opposite to each other;
• a touch component disposed on the first surface of the base substrate;
• and
• an electro-static discharge protection component disposed outside the touch component,
• wherein the electro-static discharge protection component comprises:
• a first protection portion disposed on the first surface of the base substrate;
• a second protection portion disposed in a different layer from the first protection portion;
• and
• a connection portion connecting the first protection portion with the second protection portion;
• wherein the touch component comprises a plurality of first electrodes and a plurality of second electrodes disposed crosswise;
• wherein the touch substrate further comprises a bond pad, the first electrode is connected to the bond pad via the first wiring disposed on the first surface of the base substrate, and the second electrode is connected to the bond pad via a second wiring disposed on the first surface of the base substrate;
• and
• wherein the touch substrate further comprises a protective wiring which is linear and disposed on the first surface of the base substrate to surround the touch component, the first wiring and the second wiring, and disposed between the first and second wirings and the first protection portion of the electro-static discharge protection component.
