Electrode array of touch panel

An electrode array of a touch panel, comprising:

• a plurality of rhombus-shaped electrodes arranged along a first direction and interconnected in the first direction;
• a plurality of dumbbell-shaped electrodes arranged along a second direction, each of the dumbbell-shaped electrodes having a first enlarged part, a second enlarged part, and a narrow part connecting between the first enlarged part and the second enlarged part, each rhombus-shaped electrode being disposed between two adjacent ones of the dumbbell-shaped electrodes along the second direction;
• a plurality of bridge wires for electrically coupling the two first enlarged parts of the two adjacent dumbbell-shaped electrodes and electrically coupling the two second enlarged parts of the two adjacent dumbbell-shaped electrodes, respectively;
• and
• a plurality of point discharge components, the point discharge components being disposed on edges of the rhombus-shaped electrodes and edges of the first enlarged parts and the second enlarged parts of the dumbbell-shaped electrodes.
