wherein the through hole is located in the non-active area;
wherein the substrate is a bendable flexible substrate;
a strain sensor, wherein the strain sensor is arranged on the back surface of the substrate and in the active area, and is configured to detect a stress deformation parameter of the driving wiring.

2. The display panel according to claim 1 , wherein a material of the substrate is polyimide (PI).

3. The display panel according to claim 1 , wherein the strain sensor comprises a conductive wiring arranged in a serpentine route manner, and the conductive wiring comprises a third end and a fourth end; the solder pad comprise a first solder pad and a second solder pad, wherein the third end of the conductive wiring is connected to the first solder pad, and the fourth end of the conductive wiring is connected to the second solder pad.

4. The display panel according to claim 1 , wherein
the through hole defined on the substrate comprises a first through hole on a first side of the substrate and a second through hole on a second side adjacent to the first side;
the driving wiring carried on the substrate comprises a first driving wiring and a second driving wiring;
the solder pad being arranged on the back surface of the substrate comprises a third solder pad and a fourth solder pad;
wherein a fifth end of the first driving wiring is located on the front surface of the substrate, and a sixth end of the first driving wiring is connected to the third solder pad via the first through hole; a seventh end of the second driving wiring is located on the front surface of the substrate, and a eighth end of the second driving wiring is connected to the fourth solder pad via the second through hole; the first through hole and the second through hole are located in the non-active area and around the active area; and the third solder pad and the fourth solder pad are located on a same side of the substrate.

5. The display panel according to claim 4 , wherein
the through hole defined on the substrate further comprises a third through hole on a third side opposite to the first side;
the driving wiring carried on the substrate further comprises a third driving wiring;
the solder pad being arranged on the back surface of the substrate further comprises a fifth solder pad located on the same side where the third solder pad and the fourth solder pad are arranged on;
the first side and the third are parallel to the side where the third solder pad, the fourth solder pad, and the fifth solder pad are arranged on;
the sixth end of the first driving wiring is connected to the third solder pad via the first through hole along a first direction; and a ninth end of the third driving wiring is connected to the fifth solder pad via the third through hole along a third direction opposite to the first direction.

6. The display panel according to claim 1 , wherein the first end is located in the active area and the second end is located in the non-active area.

7. A display device comprising a circuit board and a display panel; the display panel comprising:
a substrate defining a through hole;
a driving wiring carried on the substrate;
a solder pad being arranged on a back surface of the substrate;
an active area; and
a non-active area around the active area;
