Display panel, motherboard and mini LED display device

A motherboard comprising a plurality of panel regions, each panel region corresponding to a to-be-tested display panel, each panel region comprising:

• a first edge extending along a first direction;
• a display region and a test region arranged along a second direction intersecting the first direction;
• and
• a plurality of first electrostatic discharge protection wires extending from one side of the display region adjacent to the test region to the first edge,
• wherein the test region is located between the display region and the first edge and comprises a plurality of test pads, at least two test pads of the plurality of test pads being arranged along the first direction, and adjacent test pads of the at least two test pads in the first direction are spaced apart by at least two first electrostatic discharge protection wires of the plurality of first electrostatic discharge protection wires, wherein each of the plurality of first electrostatic discharge protection wires comprises a first line segment and a second line segment, the first line segment located between two adjacent test pads, and the second line segment connected to the first line segment, and wherein a distance between adjacent first line segments that are located between two adjacent test pads in the first direction is less than a distance between adjacent second line segments in the first direction.

A mini LED display device, comprising a display panel, wherein the display panel comprises:

• a panel edge extending along a first direction;
• a display region and a test region arranged along a second direction intersecting the first direction;
• and
• a plurality of first electrostatic discharge protection wires extending from one side of the display region adjacent to the test region to the panel edge,
• wherein the test region is located between the display region and the panel edge and comprises a plurality of test pads, at least two test pads of the plurality of test pads being arranged along the first direction, and adjacent test pads of the at least two test pads in the first direction are spaced apart by at least two first electrostatic discharge protection wires of the plurality of first electrostatic discharge protection wires, and
• wherein each of the plurality of first electrostatic discharge protection wires comprises a first line segment and a second line segment, the first line segment located between two adjacent test pads, and the second line segment is adjacent to the panel edge, and wherein a distance between adjacent first line segments located between two adjacent test pads in the first direction is less than a distance between adjacent second line segments in the first direction.
