Touch substrate, touch panel and method of fabricating a touch panel

A touch panel comprising a touch substrate, wherein the touch substrate comprises a plurality of regions;

• wherein one of the plurality of regions comprises:
• a first electrode comprising a plurality of electrode portions, a respective one of the plurality of electrode portions comprises at least one elongated component;
• a plurality of second electrodes that correspond with the first electrode, and the plurality of second electrodes are insulated from the first electrode;
• a first touch signal line connecting the plurality of electrode portions together;
• a plurality of second touch signal lines respectively connected to the plurality of second electrodes;
• and
• an electrostatic discharge line;
• wherein the respective one of the plurality of electrode portions and a respective one of the plurality of second electrodes interleave with each other;
• the respective one of the plurality of electrode portions comprises:
• a trunk;
• a plurality of first branches extending from the trunk along a first direction away from the trunk;
• and
• a plurality of second branches extending from the trunk along a second direction away from the trunk;
• wherein the electrostatic discharge line comprises a -shaped comb ridge outside a touch region comprising the plurality of regions, and a plurality of comb teeth inside the touch region and respectively connected with the -shaped comb ridge;
• the -shaped comb ridge encircles three sides of the touch region;
• and
• a respective one of the plurality of comb teeth extends into a space between two adjacent regions of the plurality of regions;
• wherein the first direction is opposite to the second direction;
• the plurality of first branches respectively connect to a plurality of first portions of the trunk;
