Optionally, the sheet resistance R of the electrostatic discharge trace 5 satisfies 0.056 Ω/□ ≤ R ≤ 0.44 Ω/□, so as to better conduct away the static electricity generated near the first non-display area 21.
Illustratively, with continued reference to fig. 2, the touch electrodes 3 include first touch electrodes 31 extending along the first direction x and arranged along the second direction y, and second touch electrodes 32 extending along the second direction y and arranged along the first direction x.

Optionally, as shown in fig. 2, the first sub-touch electrodes 310 are connected to each other through first connection portions 311, the first connection portions 311 and the first sub-touch electrodes 310 are located in the same layer, that is, the first connection portions 311 and the first sub-touch electrodes 310 are formed by patterning the same conductive layer; the second sub-touch electrodes 320 are connected to each other through second connection portions 321, and the second connection portions 321 and the second sub-touch electrodes 320 are disposed in different layers, that is, the second connection portions 321 and the second sub-touch electrodes 320 are formed by patterning different conductive layers.

Optionally, when the esd trace is disposed in the display panel, the position of the esd trace may have various designs, for example, as shown in fig. 4, fig. 4 is a schematic cross-sectional view along BB' of fig. 2, wherein the esd trace 5 and the dummy electrode 4 are disposed in the same layer, and the dummy electrode 4 near the edge of the first non-display area 21 is in contact connection with the esd trace 5.
Alternatively, the esd trace 5 and the dummy electrode 4 may be disposed on different layers, as shown in fig. 5, fig. 5 is another schematic cross-sectional view along BB' of fig. 2, in which the esd trace 5 and the dummy electrode 4 are disposed in different layers, that is, the esd trace 5 and the dummy electrode 4 are formed by patterning different conductive layers. Specifically, an insulating layer 7 is further included between the electrostatic discharge trace 5 and the dummy electrode 4, and the electrostatic discharge trace 5 and the dummy electrode 4 are connected through a via 70 in the insulating layer 7.
Optionally, in the embodiment of the present invention, based on the setting of the first non-display area 21, the setting manner of the touch electrode may also be selected in various ways, specifically, for example, as shown in fig. 6, fig. 6 is a schematic diagram of a touch electrode provided in the embodiment of the present invention, where no touch electrode is disposed in the first non-display area 21. That is, the first and second touch electrodes 31 and 32 are disconnected at a position corresponding to the first non-display area 21. Specifically, as shown in fig. 7, fig. 7 is an enlarged schematic view of the dotted line area in fig. 6, wherein the first touch electrodes 31 located at two sides of the first non-display area 21 are electrically connected through the first connecting trace 81, the second touch electrodes 32 located at two sides of the first non-display area 21 are electrically connected through the second connecting trace 82, and the first connecting trace 81 and the second connecting trace 82 are not connected to each other. As shown in fig. 6 and 7, the electrostatic discharge trace 5 is located inside the touch electrode, that is, the touch electrode surrounds the electrostatic discharge trace 5, and by such arrangement, the embodiment of the invention can prevent the electrostatic from being transmitted to the touch electrode located at the periphery of the first non-display area 21, thereby ensuring the accuracy of the touch operation.
It should be noted that the shapes of the first connection trace 81 and the second connection trace 82 in fig. 7 are only schematic, and in actual design, the first connection trace 81 and the second connection trace 82 may be designed according to the shape of the first non-display area 21 and the shape of the touch electrode 3, for example, the first connection trace 81 and the second connection trace 82 may be designed to be a folded line shape as shown in fig. 7, or may be designed to be a curved line shape, which is not limited in this embodiment of the invention.
Alternatively, as shown in fig. 8, fig. 8 is a schematic view of another touch electrode according to an embodiment of the present invention, wherein the touch electrodes are disposed in both the display area 1 and the first non-display area 21. That is, the touch electrode is configured as a whole surface, a hole is formed in the array substrate (not shown) opposite to the touch electrode layer as the first non-display area 21, and the touch electrode is usually made of a transparent metal oxide such as indium tin oxide or indium zinc oxide, so that the touch electrode designed as a whole surface does not affect the normal operation of the functional device such as the camera in the first non-display area 21. In addition, the touch electrode is designed to be of a whole-surface structure, so that the hole digging design of the touch electrode is avoided, and the complexity of the process is reduced. In this case, the electrostatic discharge trace 5 and the touch electrode are located on different layers. Optionally, as shown in fig. 9, fig. 9 is a schematic cross-sectional view along CC' of fig. 8, wherein the electrostatic discharge trace 5 and the second connection portion 321 are located at the same layer, that is, the electrostatic discharge trace 5 and the second connection portion 321 are formed by patterning the same conductive layer. In the manufacturing process, the electrostatic discharge trace 5 and the second connection portion 321 may be manufactured by the same process.
Illustratively, with continued reference to fig. 7, in which the dummy electrodes 4 are connected to each other by the third connection portions 331, for example, the second connection portions 321 and the third connection portions 331 may be disposed on the same layer, so that the second connection portions 321 and the third connection portions 331 may be simultaneously fabricated by the same process during the fabrication of the touch electrodes. Alternatively, the material of the electrostatic discharge trace 5 may be a metal or a transparent metal oxide. Illustratively, the metal material may be any one selected from copper, silver, titanium, and the like. The transparent metal oxide material can be any one of indium tin oxide, indium zinc oxide, indium gallium zinc oxide and the like.
Illustratively, the shape of the closed loop trace surrounded by the electrostatic discharge trace 5 matches the shape of the first non-display area 21, and the shape of the closed loop trace surrounded by the electrostatic discharge trace 4 may be any one of a circle, an ellipse, and a polygon according to the design of the shape of the first non-display area 21. For example, when the display panel is subjected to a hole-digging design by using a cutting process to form the first non-display area 21, the shape of the first non-display area 21 and the shape of the closed-loop trace surrounded by the electrostatic discharge trace 5 may be designed to be a polygon, so as to reduce the difficulty of the cutting process. Of course, the shape of the first non-display area 21 and the shape of the closed-loop trace surrounded by the electrostatic discharge trace 5 may also be designed to be circular, so that the formed display panel is more beautiful.

In addition, by arranging the touch electrodes and the dummy electrodes, the display device can realize a touch function, and by arranging the dummy electrodes between the adjacent touch electrodes, the edge visibility of the touch electrodes can be reduced, and the display effect of the display device can be improved.
In addition, in the embodiment of the invention, the electrostatic discharge wire surrounding the first non-display area 21 is arranged, and the electrostatic discharge wire is connected to the electrostatic protection circuit located in the second non-display area through the dummy electrode, so that static electricity generated around the first non-display area 21 can be transmitted to the electrostatic protection circuit through the electrostatic discharge wire and the dummy electrode in sequence, thereby avoiding accumulation of the static electricity in the display panel, ensuring the accuracy of signals in the display panel, and reducing the risk of electrostatic breakdown of each electronic device in the display panel.
