[0021] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings. The technical solutions described below are for illustrative purposes only and should not be construed as limiting the scope of protection of this application.

[0022] Furthermore, the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are merely used to distinguish different technical features. The terms "multiple" and similar words indicate two or more unless otherwise expressly specified.

[0023] Embodiments of this application provide a display panel 10, see reference. Figure 1 , Figure 2 , Figure 5 The display panel 10 includes a display area AA and a non-display area NA disposed on at least one side of the display area AA. The display panel 10 also includes a first power line 100, multiple connection lines 200, multiple touch lines 300, and a shielding line 400.

[0024] Specifically, the first power supply trace 100 is located in the non-display area NA; the connection trace 200 is located in the non-display area NA; a portion of the touch trace 300 is located in the non-display area NA, and the film layer containing the touch trace 300 is located above the film layer containing the first power supply trace 100; multiple touch traces 300 are electrically connected to a portion of the connection traces 200 through multiple first cable exchange holes K1; the shielding trace 400 is located in the non-display area NA, and the film layer containing the shielding trace 400 is located above the first power supply trace 100. Between the film layer where the power trace 100 is located and the film layer where the touch trace 300 is located; wherein, the potential of the shielding trace 400 is lower than the potential of the touch trace 300, and the potential of the shielding trace 400 is higher than the potential of the first power trace 100, and from a viewing angle along the thickness direction H of the display panel 10, a portion of the shielding trace 400 overlaps with a portion of the first power trace 100, and a portion of the shielding trace 400 protrudes from an edge of the first power trace 100 away from the display area AA.

[0025] To shield the touch signal from interference from the square wave signal of the array substrate signal line of the touch display panel, conventional solutions use a VSS (Voltage Supply Slave, low-level signal of the driving circuit) trace in the lower bezel area of ​​the touch display panel. However, because the potential of the VSS trace is less than 0, typically around -3V, while the voltage signal potential of the touch trace is typically around 5V, there is a significant voltage difference between the VSS trace and the touch signal trace. This makes the metal wires in the wire replacement hole prone to electrochemical corrosion, causing different metal wires in the wire replacement hole to detach and resulting in bulging of the wire replacement hole in the lower bezel area of ​​the touch display panel. Therefore, the technical solution of this application provides a display panel 10, in which the film layer where the touch trace 300 is located is situated above the film layer where the first power trace 100 is located. Multiple touch traces 300 are electrically connected to a portion of the connecting traces 200 through multiple first wire exchange holes K1. The film layer where the shielding trace 400 is located is situated between the film layer where the first power trace 100 is located and the film layer where the touch trace 300 is located. The potential of the shielding trace 400 is set lower than the potential of the touch trace 300, and higher than the potential of the first power trace 100. From a viewing angle along the thickness direction H of the display panel 10, a portion of the shielding trace 400 overlaps with a portion of the first power trace 100, and a portion of the shielding trace 400 protrudes from an edge of the first power trace 100 away from the display area AA. This technical solution adds a shielding trace 400 with a higher potential than the first power trace 100 between the first power trace 100 and the touch trace 300. This makes the voltage difference between the touch trace 300 and the shielding trace 400 smaller than the voltage difference between the touch trace 300 and the first power trace 100. Compared with conventional display panels, this solution helps to shield the interference of the square wave signal of the signal line of the array substrate on the touch signal, thereby improving the stability of the touch of the display panel 10. On the other hand, it reduces the voltage difference between the shielding trace 400 and the touch trace 300 of the array substrate, thereby reducing the risk of electrochemical corrosion of the touch trace 300 and the first connection trace 210 at the first line exchange hole K1. It also reduces the risk of detachment of some touch traces and some first connection traces located in the first line exchange hole, thereby improving the problem of bulging of the line exchange hole of the display panel 10.

[0026] In this embodiment, the display panel 10 is a touch display panel 10, which includes a display substrate, specifically an OLED display substrate.

[0027] In this embodiment, the non-display area NA includes the lower border area NA1, which includes a bend area and a line-changing area NA1a.

[0028] In this embodiment, the shielding trace 400 includes a grounding trace 500.

[0029] In this embodiment, the first power supply trace 100 includes a VSS (Voltage Supply Slave, low level of the drive circuit) trace.

[0030] In this embodiment, the display panel 10 further includes a second power supply trace, which includes a VDD (Voltage Drain Driver, high level of the driving circuit) trace.

[0031] It is understandable that the voltage signal input to the VDD trace is greater than the voltage signal input to the VSS trace.

[0032] It is understood that the display panel 10 includes an array substrate, fan-out traces, GOA traces, and CLK traces integrated on the array substrate, and outputs square wave signals to control the display operation.

[0033] In this embodiment, from a perspective along the thickness direction H of the display panel 10, a portion of the touch trace 300 overlaps with a portion of the shielding trace 400 and a portion of the first power trace 100.

[0034] In this embodiment, a plurality of the first wire-changing holes K1 are arranged at intervals in the first direction L.

[0035] In this embodiment, reference Figure 2 The multiple connection traces 200 include a first connection trace 210 and a second connection trace 220, with the second connection trace 220 spaced apart from the first connection trace 210; the display panel 10 also includes a ground trace 500, a portion of which is located in the non-display area NA, and the film layer on which the ground trace 500 is located is above the film layer on which the first power trace 100 is located; wherein, the touch trace 300 is electrically connected to the first connection trace 210 through the first line exchange hole K1, the ground trace 500 is electrically connected to the second connection trace 220 through the second line exchange hole K2, and the shielding trace 400 is electrically connected to the second connection trace 220 through the third line exchange hole K3.

[0036] It is understood that in this embodiment, the touch trace 300 is electrically connected to the first connection trace 210 through the first line-changing hole K1, the ground trace 500 is electrically connected to the second connection trace 220 through the second line-changing hole K2, and the shielding trace 400 is electrically connected to the second connection trace 220 through the third line-changing hole K3. This allows the ground trace 500 to provide a GND signal to the shielding trace 400. Since the GND signal potential is higher than the VSS signal potential, the voltage difference between the shielding trace 400 and the touch trace 300 of the array substrate is reduced compared to the conventional solution of the display panel 10. This weakens the influence of the electric field on the line-changing hole of the lower bezel area NA1, thereby improving the problem of bulging of the line-changing hole of the display panel 10.

[0037] It should be noted that the GND signal is usually the ground voltage, which is 0V.

[0038] In this embodiment, the first cable switching hole K1, the second cable switching hole K2, and the third cable switching hole K3 are all located in the cable switching area NA1a, and the third cable switching hole K3 is located on the extension line of the line connecting the centers of the plurality of first cable switching holes K1.

[0039] In this embodiment, reference Figure 2 The first power supply trace 100 includes a first main body 110 and at least two first branches 120 connected to the first main body 110, the first branches extending in a direction away from the display area; the shielding trace 400 includes a second main body 410 and at least two second branches 420 connected to the second main body 410, the second branches extending in a direction away from the display area; wherein, the second branch 420 is electrically connected to the second connection trace 220 through the third cable replacement hole K3, and from a perspective along the thickness direction H of the display panel 10, a portion of the second main body 410 protrudes from an edge of the first main body 110 away from the display area AA.

[0040] It is understood that in this embodiment, the first power trace 100 is configured to include a first main body 110 and at least two first branches 120 connected to the first main body 110, with the first branches 120 extending in a direction away from the display area AA; the shielding trace 400 includes a second main body 410 and at least two second branches 420 connected to the second main body 410, with the second branches 420 extending in a direction away from the display area AA; wherein the second branches 420 are electrically connected to the second connecting trace 220 through the third switching hole K3, and from a perspective along the thickness direction H of the display panel 10, a portion of the second main body 410 protrudes from an edge of the first main body 110 away from the display area AA, so that the shielding trace 400 can form a semi-enclosed structure, thereby improving the shielding effect of the shielding trace 400 on the first power trace 100, and reducing the interference of the signal of the first power trace 100 on the switching hole of the switching area NA1a.

[0041] Specifically, the at least two first branches 120 include two first branches 120 located at both ends of the first main body 110, and the at least two second branches 420 include two second branches 420 located at both ends of the second main body 410.

[0042] In this embodiment, the length direction of the first main body portion 110 is the same as the length direction of the second main body portion 410.

[0043] In this embodiment, reference Figure 1 The connecting trace 200 extends in a second direction M, which is perpendicular to the first direction L. The length direction of the first main body is the first direction L. It can be understood that the first direction L can be the direction of the rows of the display panel 10, and the second direction M can be the direction of the columns of the display panel 10.

[0044] In this embodiment, reference Figure 2 The grounding trace 500 and the touch trace 300 are spaced apart, and the second branch 420 is located between the grounding trace 500 and the first branch 120. By spaced the grounding trace 500 and the touch trace 300, and by positioning the second branch 420 between the grounding trace 500 and the first branch 120, the second branch 420 can shield the signal from the first branch 120, thereby ensuring the shielding effect of the shielding trace 400.

[0045] In this embodiment, there is a gap between the second main body 410 and the third cable switching hole K3, and the gap is not less than 20 μm. Specifically, the gap is 21 μm, 22 μm, 23 μm, 24 μm, 25 μm, 26 μm, 27 μm, 28 μm, 29 μm, 30 μm, 31 μm, 32 μm, 33 μm, 34 μm, 35 μm, 36 μm, 37 μm, 38 μm, 39 μm, 40 μm, 41 μm, 42 μm, 43 μm, 44 μm, 45 μm, 46 μm, 47 μm, 48 μm, 49 μm, or 50 μm.

[0046] In this embodiment, the width of the second main body portion is smaller than the width of the first main body portion.

[0047] Understandably, since the shielding trace 400 and the first power trace 100 are located on different film layers, other signal traces need to be arranged on the film layer where the shielding trace 400 is located. If the area occupied by the shielding trace 400 is too large, it is difficult to arrange other signal lines. Therefore, by setting the width of the second main body to be smaller than the width of the first main body, the area occupied by the shielding trace 400 can be reduced, saving wiring space in the lower border area NA1 of the non-display area NA.

[0048] In this embodiment, the overlap width between the second main body portion and the first main body portion is not less than 5 μm. By setting the overlap width between the second main body portion and the first main body portion to not less than 5 μm, the second main body portion can effectively cover the edge of the first main body portion, thereby reducing the interference of the electric field of the first power supply trace on the cable replacement hole caused by the second main body portion not effectively covering the edge of the first main body portion.

[0049] In this embodiment, reference Figure 3 The display panel 10 includes a substrate 101, a first metal layer 102, a first organic planarization layer 103, a second metal layer 104, a second organic planarization layer 105, and a third metal layer 106.

The second metal layer 104 is disposed on a surface of the first organic planarization layer 103 away from the substrate 101. The second organic planarization layer 105 is disposed on a surface of the second metal layer 104 away from the substrate 101. The third metal layer 106 is disposed on a surface of the second organic planarization layer 105 away from the substrate 101. The first power supply trace 100 and the connection trace 200 are located on the first metal layer 102, the ground trace 500 and the touch trace 300 are located on the third metal layer 106, and the shielding trace 400 is located on the second metal layer 104.

[0050] In this embodiment, the display panel 10 further includes an interlayer dielectric layer 109, which is disposed between the second organic planarization layer 105 and the third metal layer 106.

[0051] In this embodiment, reference Figure 4 The display panel 10 includes a substrate 101, a first metal layer 102, a first organic planarization layer 103, a second metal layer 104, a second organic planarization layer 105, a third metal layer 106, and a fourth metal layer 107; the first metal layer 102 is disposed on the substrate 101; the first organic planarization layer 103 is disposed on a surface of the first metal layer 102 away from the substrate 101; the second metal layer 104 is disposed on a surface of the first organic planarization layer 103 away from the substrate 101; the second organic planarization layer 105 is disposed on a surface of the first organic planarization layer 103 away from the substrate 101; the second organic planarization layer 106 is disposed on a surface of the first metal layer 102 away from the substrate 101; the second organic planarization layer 107 is disposed on a surface of the first metal layer 102 ... metal layer 107 is disposed on a surface of the first metal layer 102 away from the substrate 101; the second organic planarization layer 107 is disposed on a surface of the first metal layer 102 away from the substrate 101; the second metal layer 107 is disposed on a surface of the first metal layer 102 away from the substrate 101; the second metal layer 108 is disposed on a surface of the first metal layer 102 away from the substrate 101; the second metal layer 109 is disposed on a surface of the first metal layer 102 away from the substrate 101; the second metal layer 100 is disposed on a surface of the first metal layer The second metal layer 104 is disposed on a surface away from the substrate 101; the third metal layer 106 is disposed on a surface of the second organic planarization layer 105 away from the substrate 101; the fourth metal layer 107 is disposed on the side of the third metal layer 106 away from the substrate 101; wherein, the first power supply trace 100 and the connection trace 200 are located on the first metal layer 102, the shielding trace 400 is located on the third metal layer 106, and the ground trace 500 and the touch trace 300 are located on the fourth metal layer 107.

[0052] In this embodiment, the display panel 10 further includes a third organic planarization layer 108, which is disposed on a surface of the third metal layer 106 away from the substrate.

[0053] In this embodiment, the display panel 10 further includes an interlayer dielectric layer 109, which is disposed between the third organic planarization layer 108 and the fourth metal layer 107.

[0054] The technical concept of the technical solution in this application is as follows: To shield the touch signals from the square wave signals of the array substrate signal lines of the touch display panel, conventional solutions include a VSS (Voltage Supply Slave, low-level signal of the driving circuit) trace and a VSS metal block in the lower bezel area of ​​the touch display panel. However, because the potential of the VSS trace is less than 0, typically around -3V, while the voltage signal potential of the touch trace is typically around 5V, a significant voltage difference exists between the VSS metal block and the touch signal trace. During reliability testing of the display panel, moisture can easily enter the reconnection holes from the area between the organic planarization layer and the interlayer dielectric layer. This causes electrochemical corrosion of the touch traces and connection traces at the reconnection holes, and oxidation and gas release in the interlayer dielectric layer below the touch traces. This leads to the peeling of the touch traces from the connection traces, resulting in bulging of the reconnection holes in the lower bezel area of ​​the touch display panel. Therefore, the technical solution of this application provides a display panel 10, in which the film layer where the touch trace 300 is located is situated above the film layer where the first power trace 100 is located. Multiple touch traces 300 are electrically connected to a portion of the connecting traces 200 through multiple first wire exchange holes K1. The film layer where the shielding trace 400 is located is situated between the film layer where the first power trace 100 is located and the film layer where the touch trace 300 is located. The potential of the shielding trace 400 is set lower than the potential of the touch trace 300, and higher than the potential of the first power trace 100. From a viewing angle along the thickness direction H of the display panel 10, a portion of the shielding trace 400 overlaps with a portion of the first power trace 100, and a portion of the shielding trace 400 protrudes from the first power trace 100 away from the display area A. A; that is, this technical solution adds a shielding trace 400 with a higher potential than the first power trace 100 between the first power trace 100 and the touch trace 300, so that the voltage difference between the touch trace 300 and the shielding trace 400 is smaller than the voltage difference between the touch trace 300 and the first power trace 100. Compared with the conventional solution of the display panel 10, on the one hand, it is beneficial to shield the interference of the square wave signal of the signal line of the array substrate on the touch signal, thereby improving the touch stability of the display panel 10. On the other hand, it reduces the voltage difference between the shielding trace 400 of the array substrate and the touch trace 300, so as to reduce the risk of electrochemical corrosion between the touch trace 300 and the first connection trace 210 at the first line exchange hole K1, and thus reduce the risk of peeling between the touch trace 300 and the connection trace 200, thereby improving the problem of bulging of the line exchange hole of the display panel 10.
