Abstract
The present invention discloses an electrostatic discharge structure for a touch panel module to prevent ESD current flowing from the touch panel to the circuit board and damaging the electronic elements. The touch panel module comprises a touch panel and a circuit board. The circuit board has a connection portion connecting the circuit board with the touch panel. The connection portion has a plurality of sensing wires, two ends of each sensing wire are respectively electrically connected with one sensing unit of the touch panel and one sensor chip of the circuit board. The connection portion comprises at least one grounding solder pad and an electric-conduction structure covering thereon. The electric-conduction structure electrically connects the grounding solder pads to direct away the static.
