The gate driving connection line group 74 is in a folded line shape extending along the first direction D1 . One end of the gate driving connection line group 74 is connected to the gate driving access line group 73 , and the other end of the gate driving connection line group 74 is connected to the driving chip area 2033 .

[0073] In an exemplary embodiment, the orthographic projections of the gate driving connection line group 74 on the substrate overlap with portions of the orthographic projections of the first power supply connection line 13 and the second power supply connection line 23 on the substrate.

[0074] In an exemplary embodiment, on a plane perpendicular to the display panel, the gate drive fan-out line group 71 can be located in the same film layer as at least one of the first gate layer and the second gate layer of the touch control area, and can be prepared by the same conductive material through the same preparation process. The gate drive bending line group 72 can be located in the same film layer as the second source and drain electrode layer of the touch control area, and can be prepared by the same conductive material through the same preparation process. The gate drive access line group 73 can be located in the same film layer as at least one of the first gate layer, the second gate layer and the first source and drain electrode layer of the touch control area, and can be prepared by the same conductive material through the same preparation process. The gate drive connection line group 74 can be located in the same film layer as at least one of the first gate layer and the second gate layer of the touch control area, and can be prepared by the same conductive material through the same preparation process.

[0075] The display panel of the disclosed embodiment is located in the same film layer as at least one of the first gate layer and the second gate layer of the touch area through the gate drive connection line group 74, so that the drive connection line group 74 and the first power access line 13 and the second power access line 23 are located in different film layers, thereby avoiding the gate drive connection line group 74 from intersecting the first power access line 13 and the second power access line 23.

Figure 8b The touch signal line group shown can be Figure 8a In an exemplary embodiment, as shown in FIG. Figure 8a and Figure 8b As shown, the structure of the binding area of ​​the display panel of the embodiment of the present disclosure is Figure 4 The structures of the binding areas of the display panels shown are substantially the same, except that the structure of the touch connection line group 5 of the binding area of ​​the display panel in the embodiment of the present disclosure is different.

[0077] In an exemplary embodiment, on a plane perpendicular to the display panel, the orthographic projection of the touch connection line group 5 on the substrate partially overlaps with the orthographic projections of the first power connection line 13 and the second power connection line 23 on the substrate.

[0078] In an exemplary embodiment, the touch connection line group 5 and the second power access line 23 are located in different film layers, and the touch connection line group 5 can be located on the side of the second power access line 23 away from the substrate. For example, the second power access line 23 and at least one of the first source-drain electrode layer and the second source-drain electrode layer of the touch region are located in the same film layer, and can be prepared by the same conductive material and the same preparation process; the touch connection line group 5 and at least one of the first metal grid layer and the second metal grid layer of the touch region are located in the same film layer, and can be prepared by the same conductive material and the same preparation process.

[0079] In an exemplary embodiment, the touch connection line group 5 and the first metal grid layer and the second metal grid layer of the touch area are located in the same film layer and can be made of the same conductive material through the same preparation process, thereby reducing the impedance of the touch connection line group 5 .

The distance between the overlapping area of ​​the touch connection line group 5 and the second power access line 23 in the direction perpendicular to the display panel is increased, thereby reducing the parasitic capacitance between the touch connection line group 5 and the second signal line group 2, and reducing the occurrence of undesirable phenomena such as water ripples in the touch display and abnormal touch reporting.

[0083] The second power lead line of the second power signal line 2 of the display panel of the disclosed embodiment is located on the side of the touch lead line group of the touch signal line group 4 away from the center line O, so that the second power lead line of the second power signal line 2 is a signal line, thereby reducing the impedance of the second power signal line 2 and improving the signal strength of the second power signal line 2.

[0084] In an exemplary embodiment, an orthographic projection of the touch access line group 43 of the touch signal line group 4 on the substrate partially overlaps with an orthographic projection of the second power access line 23 of the second power signal line 2 on the substrate.

[0085] In an exemplary embodiment, the touch connection line group 5 is in a straight line or a folded line shape, one end of the touch connection line group 5 is connected to the touch bending line group 42 of the touch signal line group 4, and the other end of the touch connection line group 5 is connected to the antistatic area 2032.

[0088] In the display panel of the disclosed embodiment, the orthographic projection of the touch connection line group 5 on the substrate does not overlap with the orthographic projection of the second power signal line 2 on the substrate, thereby eliminating the parasitic capacitance between the touch connection line group 5 and the second signal line group 2, reducing the mutual interference between the second power signal line 2 and the touch connection line group 5, and reducing the occurrence of undesirable phenomena such as water ripples on the touch display and abnormal touch reporting.

[0089] In an exemplary embodiment, the touch connection line group 5 and at least one of the first gate layer and the second gate layer of the touch region are located in the same film layer and can be made of the same conductive material through the same preparation process.
