[0045] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0046] An embodiment of the present application provides a display panel, which includes a display area and a frame area arranged on one side of the display area. The display panel also includes a substrate, at least two signal wiring groups arranged at intervals, and an organic insulating layer. The signal wiring group is arranged on the substrate and is located in the frame area. Each signal wiring group includes a plurality of signal wirings arranged at intervals. The signal types transmitted by any two adjacent signal wiring groups are different. The organic insulating layer is arranged on the signal wiring group. A linear insulating pattern is arranged on the organic insulating layer. The linear insulating pattern is arranged between adjacent signal wiring groups and insulates the signal wiring groups.
[0047] In an embodiment of the present application, the signal wiring in the border area is divided into at least two signal wiring groups that are spaced apart and transmit different signal types, and a linear insulation pattern is provided on the organic insulation layer between adjacent signal wiring groups, so that the adjacent signal wiring groups are insulated and separated by the linear insulation pattern to prevent electrochemical corrosion from occurring between adjacent signal wiring groups that transmit different signal types, thereby reducing the risk of corrosion of the signal wiring in the border area and improving the reliability of the display panel.
[0048] See also Figure 1 and Figure 2 , Figure 1 A top view of a display panel provided in an embodiment of the present application, Figure 2 for Figure 1 In the enlarged schematic diagram at a, the display panel 100 includes a display area AA and a frame area BA disposed on one side of the display area AA.
[0049] See also Figure 3 and Figure 4 , Figure 3 for Figure 2 The enlarged schematic diagram of point b in the middle, Figure 4The cross-sectional view of the display panel along the A-A' direction provided for the embodiment of the present application, the display panel 100 includes a substrate 1, at least two signal wiring groups 2 arranged at intervals, and an organic insulating layer 3. The signal wiring group 2 is arranged on the substrate 1 and is located in the frame area BA. Each signal wiring group 2 includes a plurality of signal wirings 20 arranged at intervals. The signal types transmitted by any two adjacent signal wiring groups 2 are different. The organic insulating layer 3 is arranged on the signal wiring group 2, and a linear insulating pattern 30 is arranged on the organic insulating layer 3. The linear insulating pattern 30 is arranged between adjacent signal wiring groups 2 and isolates the adjacent signal wiring groups 2, which can not only avoid signal crosstalk between signal wirings transmitting different signal types, but also prevent electrochemical corrosion between adjacent signal wiring groups transmitting different signal types, thereby reducing the risk of corrosion of the signal wiring in the frame area and improving the reliability of the display panel.
[0050] It should be noted that the signal type may include voltage level characteristics and direction characteristics of the signal, and each signal wiring group 2 is used to transmit a signal with corresponding characteristics to achieve accurate classification and efficient transmission of the signal.
[0051] In some embodiments, see Figure 3 and Figure 4 The signal routing group 2 includes a first sub-signal routing group 21 and a second sub-signal routing group 22. The first sub-signal routing group 21 and the second sub-signal routing group 22 are arranged at intervals. The first sub-signal routing group 21 transmits a DC high-voltage signal, and the second sub-signal routing group 22 transmits a DC low-voltage signal. A linear insulation pattern 30 is arranged between the first sub-signal routing group 21 and the second sub-signal routing group 22.
[0052] In some embodiments, see Figure 3 and Figure 4 The linear insulating pattern 30 includes a groove 31, and the groove 31 is extended along the extension direction of the signal wiring 20. The groove 31 separates the organic insulating layer 3 above the first sub-signal wiring group 21 from the organic insulating layer 3 above the second sub-signal wiring group 22 to prevent water vapor from penetrating through the organic insulating layer 3 above the first sub-signal wiring group 21 to the organic insulating layer above the second sub-signal wiring group 22, so that the electrochemical corrosion path between the first sub-signal wiring group 21 and the second sub-signal wiring group 22 can be cut off, thereby reducing the risk of electrochemical corrosion of the first sub-signal wiring group 21 and the second sub-signal wiring group 22.
[0053] In some embodiments, see Figure 3The first sub-signal wiring group 21 includes a plurality of first signal wirings 211, and the plurality of first signal wirings 211 are arranged side by side and spaced apart. The line width of at least one first signal wiring 211 is smaller than the line width of other first signal wirings 211. By compressing the line width of part of the first signal wiring 211, the distance between the first sub-signal wiring group 21 and the second sub-signal wiring group 22 is increased. This not only reduces the risk of crosstalk between the first sub-signal wiring group 21 and the second sub-signal wiring group 22, but also facilitates the addition of a groove 31 on the organic insulating layer 3 between the first sub-signal wiring group 21 and the second sub-signal wiring group 22, so as to use the groove 31 to separate the organic insulating layer 3 above the first sub-signal wiring group 21 from the organic insulating layer 3 above the second sub-signal wiring group 22, thereby reducing the risk of electrochemical corrosion between the first sub-signal wiring group 21 and the second sub-signal wiring group 22.

By compressing the line width of the light-emitting control signal line 2111, the distance between the first sub-signal wiring group 21 and the second sub-signal wiring group 22 is increased. This not only reduces the risk of crosstalk between the first sub-signal wiring group 21 and the second sub-signal wiring group 22, but also facilitates the addition of a linear insulating pattern 30 on the organic insulating layer 3 between the first sub-signal wiring group 21 and the second sub-signal wiring group 22, so that the organic insulating layer 3 above the first sub-signal wiring group 21 is separated from the organic insulating layer 3 above the second sub-signal wiring group 22 by the linear insulating pattern 30, thereby reducing the risk of electrochemical corrosion between the first sub-signal wiring group 21 and the second sub-signal wiring group 22.
[0055] See also Figure 2 The line width of the light emitting control signal line 2111 is greater than or equal to 15 microns and less than or equal to 25 microns, and the line width of other first signal wirings 211 is greater than or equal to 40 microns and less than or equal to 85 microns.
[0056] In some embodiments, the first signal trace 211 may also include but is not limited to a gate high voltage signal line and an analog signal line. The light emitting control signal line 2111 , the gate high voltage signal line and the analog signal line all transmit a DC high voltage signal.

By compressing the line width of part of the second signal wiring 221, the distance between the first sub-signal wiring group 21 and the second sub-signal wiring group 22 is increased, which not only reduces the risk of crosstalk between the first sub-signal wiring group 21 and the second sub-signal wiring group 22, but also facilitates the addition of a linear insulating pattern 30 on the organic insulating layer 3 between the first sub-signal wiring group 21 and the second sub-signal wiring group 22, so as to use the linear insulating pattern 30 to separate the organic insulating layer 3 above the first sub-signal wiring group 21 from the organic insulating layer 3 above the second sub-signal wiring group 22, thereby reducing the risk of electrochemical corrosion between the first sub-signal wiring group 21 and the second sub-signal wiring group 22.
[0058] In some embodiments, the second sub-signal routing group 22 includes an initial light-emitting signal line 2211 and an output light-emitting signal line 2212 , and the line width of at least one of the initial light-emitting signal line 2211 and the output light-emitting signal line 2212 is smaller than the line width of other second signal routing lines 221 .
[0059] See also Figure 3 The line width of the initial light-emitting signal line 2211 and the light-emitting output signal line 2212 is greater than or equal to 15 microns and less than or equal to 25 microns, and the line width of other second signal wirings 221 is greater than or equal to 40 microns and less than or equal to 85 microns.
[0060] In some embodiments, the second signal trace 221 may also include but is not limited to a gate low voltage signal line, and the light initialization signal line 2211, the light output signal line 2212 and the gate low voltage signal line all transmit a DC low voltage signal.

In this way, the electrochemical corrosion path between the first sub-signal wiring group 21 and the third sub-signal wiring group 23 can be cut off, thereby reducing the risk of electrochemical corrosion of the first sub-signal wiring group 21 and the third sub-signal wiring group 23.
