Technical Field

[0001] This application relates to the field of display panel technology, and more particularly to a display panel and a display device. Background Technology

[0002] With the continuous development of display technology, display panels have been widely used in people's production and daily life. Among them, display panels with touch functionality are widely used. Touch display panels combine a touch panel and a display panel, enabling the display panel to simultaneously display and sense touch input.

[0003] To better meet people's needs, the wiring in the display panel can be finely adjusted to ensure a better overall effect of the touch display panel. Summary of the Invention

[0004] This application provides a display panel and a display device in which at least a portion of the fan-out traces are disposed on the same layer as the touch sub-sections. This can improve the utilization rate of some film layers, improve the structural stability of the fan-out traces, ensure the signal transmission effect of the fan-out traces, and ensure the display effect of the display panel.

[0005] In a first aspect, embodiments of this application provide a display panel, including a data signal line, a fan-out trace, and a driver chip, wherein the fan-out trace is electrically connected to the data signal line and the driver chip;

[0006] The display panel also includes a touch structure, which includes a touch sub-section;

[0007] At least a portion of the fan-out routing is disposed on the same layer as the touch sub-section.

[0008] Secondly, embodiments of this application provide a display device including the display panel described in the first aspect.

[0009] In summary, this application provides a display panel including data signal lines, fan-out traces, and a driver chip. The data signal output by the driver chip is transmitted to the data signal lines through the fan-out traces to ensure the display and other functions of the display panel. Furthermore, the display panel also includes a touch structure, which includes a touch sub-section for transmitting touch signals to ensure the touch function of the display panel. By placing at least a portion of the fan-out traces on the same layer as the touch sub-section, the utilization rate of some film layers in the display panel can be improved, providing space for other traces. Furthermore, since the ductility of structures placed in different film layers varies, placing at least a portion of the fan-out traces on the same layer as the touch sub-section can also improve the structural stability of the fan-out traces, ensuring the signal transmission effect of the fan-out traces and the display effect of the display panel.

Figures 1 to 13 As shown, this application embodiment provides a display panel 10, which includes a data signal line 110, a fan-out trace 120, and a driver chip 200. The fan-out trace 120 is electrically connected to the data signal line 110 and the driver chip 200. The display panel 10 also includes a touch structure 300, which includes a touch sub-section. At least a portion of the fan-out trace 120 is disposed on the same layer as the touch sub-section.

[0053] Among them, reference Figure 1 and Figure 2 As shown, the display panel 10 includes data signal lines 110 and a driver chip 200. The driver chip 200 provides data signals to the data signal lines 110, which transmit the data signals to the display panel 10 to drive the light-emitting elements (not specifically output in the figure) to emit light, ensuring the display function of the display panel 10. It should be noted that the display panel 10 has a relatively large number of data signal lines 110. Figure 1 and Figure 2 The data signal lines 110 are not drawn one by one; only some of the data signal lines 110 are shown on both sides of the display panel 10.

[0054] Furthermore, the display panel 10 also includes a fan-out trace 120, which is located between the driver chip 200 and the data signal line 110, and is used to transmit the data signal provided by the driver chip 200 to the data signal line 110. (Refer to...) Figure 1 and Figure 2 As shown, data signal line 110 is located in the display area AA of the display panel 10, while the driver chip 200 is located in the non-display area NA of the display panel 10. Therefore, fan-out trace 120 is used to transmit data signals from the non-display area NA to the display area AA. Further, refer to... Figure 1 and Figure 2 As shown, the fan-out trace 120 is distributed in a "fan-shaped" pattern, electrically connecting the driver chip 200 to multiple data signal lines 110. The fan-out trace 120 helps reduce the trace area occupied by the display panel 10 in the non-display area NA, thus facilitating a narrow bezel design for the display panel 10. (Refer to...) Figure 1 and 2As shown, the display panel 10 may include a fan-out area (e.g., in the non-display area NA) at the location of the display panel 10. Figure 1 As shown), it can also include two fan-out areas, such as Figure 2 The first fan-out area 1001, the bending area 1002, and the second fan-out area 1003 shown can be configured with the driver chip 200 located on the side of the fan-out area away from the display area AA.

[0055] Among them, reference Figure 1 and Figure 2 As shown, the display panel 10 also includes a touch structure 300, which includes a touch sub-section for implementing the touch function of the display panel 10. Specifically, the touch structure 300 may include a touch signal line 310 and a touch electrode 320. The touch electrode 320 is electrically connected to the touch signal line 310, which is used to transmit touch signals. Specifically, the touch electrode 320 is used to receive touch driving signals or touch sensing signals generated based on external touch, and the touch signal line 310 is used to transmit touch driving signals or touch sensing signals. Further, one end of the touch signal line 310 is electrically connected to the touch electrode 320, and the other end may be electrically connected to a touch chip or to a circuit board integrating the touch chip. Figure 1 and Figure 2 The touch signal line 310 is shown electrically connected to the circuit board 201 integrating the touch chip. That is, the touch signal line 310 is used to transmit touch signals between the touch electrode 320 and the circuit board 201, allowing the circuit board 201 to understand the touch position and / or the touch pressure, thereby realizing the touch function of the display panel 10. In this embodiment, the touch sub-section may include at least one of the touch signal line 310 and the touch electrode 320. The arrangement of the touch structure 300 in the display panel 10 can be varied, as shown in the reference... Figure 1 and Figure 2As shown, the touch structure 300 can be of a mutual capacitance type. The touch electrode 320 can include a touch driving electrode 320a and a touch sensing electrode 320b. The touch signal line 310 includes a touch driving signal line 310a and a touch sensing signal line 310b. The touch driving signal line 310a is electrically connected to the touch driving electrode 320a, and the touch sensing signal line 310b is electrically connected to the touch sensing electrode 320b. Specifically, two adjacent touch driving electrodes 320a are electrically connected via a connection bridge disposed on the same layer, and two adjacent touch sensing electrodes 320b are electrically connected via a connection bridge disposed on a different layer. Alternatively, two adjacent touch driving electrodes 320a are electrically connected via a connection bridge disposed on a different layer, and two adjacent touch sensing electrodes 320b are electrically connected via a connection bridge disposed on the same layer. This embodiment does not limit the specific type of connection. Furthermore, the touch structure 300 can also be of a self-capacitive type (not shown in the figure). Whether it is a self-capacitive or mutually capacitive touch structure 300, the touch structure 300 needs to transmit touch signals through the touch signal line 310 to ensure that the touch structure 300 can normally realize the touch function.

[0056] Further reference Figure 3 As shown, the display panel 10 includes multiple stacked film layer structures, such as a substrate 2001, a buffer layer 2002, and multiple insulating layers 2003 disposed on the buffer layer 2002 away from the substrate 2001. Multiple metal layers are disposed between two adjacent insulating layers 2003, such as a first metal layer M1, a second metal layer Mc, a third metal layer M2, a fourth metal layer M3, a fifth metal layer M4, a first touch metal layer TM1, and a second touch metal layer TM2, etc. Some signal lines in the display panel 10 can be disposed at the film layers containing the metal layers. The specific film layer structure in the display panel 10 can be adaptively adjusted according to actual needs; this application embodiment does not impose specific limitations.

[0057] At least some of the fan-out traces 120 can be disposed on the same layer as the touch electrode 320 and / or on the same layer as the touch signal line 310. This can improve the space utilization of the film layer in the display panel 10, provide space for other traces, and facilitate the compact design of the display panel 10. For example, refer to Figure 1 , Figures 4 to 9 As shown, or refer to Figure 2 , Figures 10 to 13 As shown, an example is given where at least part of the fan-out trace 120 is arranged on the same layer as the touch signal line 310.

[0058] For details, please refer to Figure 1 and Figure 4As shown in the figure, the touch driving signal line 310a in the touch signal line 310 is set in the first touch metal layer TM1 as an example. Along the thickness direction of the display panel 10, the overlapping portion of the fan-out trace 120 and the touch driving signal line 310a can be set in the film layer where the first metal layer TM1 is located; along the thickness direction of the display panel 10, the non-overlapping portion of the fan-out trace 120 and the touch driving signal line 310a can be set in the film layer where the first touch metal layer TM1 is located. (Reference) Figure 1 and Figure 5 As shown in the figure, the touch driving signal line 310a in the touch signal line 310 is set in the second touch metal layer TM2 as an example. Along the thickness direction of the display panel 10, the overlapping portion of the fan-out trace 120 and the touch driving signal line 310a can be set in the film layer where the first metal layer M1 is located; along the thickness direction of the display panel 10, the non-overlapping portion of the fan-out trace 120 and the touch driving signal line 310a can be set in the film layer where the second touch metal layer TM2 is located. (Reference) Figure 1 and Figure 6 As shown in the figure, the touch driving signal line 310a in the touch signal line 310 is set in the first touch metal layer TM1 as an example. Along the thickness direction of the display panel 10, the overlapping portion of the fan-out trace 120 and the touch driving signal line 310a can be set in the film layer where the second metal layer Mc is located; along the thickness direction of the display panel 10, the non-overlapping portion of the fan-out trace 120 and the touch driving signal line 310a can be set in the film layer where the first touch metal layer TM1 is located. (Reference) Figure 1 and Figure 7 As shown in the figure, the touch driving signal line 310a in the touch signal line 310 is set in the second touch metal layer TM2 as an example. Along the thickness direction of the display panel 10, the overlapping portion of the fan-out trace 120 and the touch driving signal line 310a can be set in the film layer where the second metal layer Mc is located; along the thickness direction of the display panel 10, the non-overlapping portion of the fan-out trace 120 and the touch driving signal line 310a can be set in the film layer where the second touch metal layer TM2 is located. Therefore, combined with Figure 1 , Figures 4 to 7 As shown, along the thickness direction of the display panel 10, the portion of the fan-out trace 120 that does not overlap with the touch signal line 310 can be set on the same layer as the touch signal line 310.

[0059] For details, please refer to Figure 1 and Figure 8As shown in the figure, the touch sensing signal line 310b in the touch signal line 310 is arranged in the film layer where the second touch metal layer TM2 is located for illustration. Along the thickness direction of the display panel 10, some fan-out traces 120 in the display panel 10 are arranged without overlapping with the touch sensing signal line 310b. Therefore, these fan-out traces 120 can be uniformly arranged on the film layer where the second touch metal layer TM2 is located. (Reference) Figure 1 and Figure 9 As shown in the figure, the touch sensing signal line 310b in the touch signal line 310 is set on the film layer where the first touch metal layer TM1 is located for illustration. Along the thickness direction of the display panel 10, some fan-out traces 120 in the display panel 10 are arranged without overlapping with the touch sensing signal line 310b. Therefore, these fan-out traces 120 can all be set on the film layer where the first touch metal layer TM1 is located. Therefore, combined with Figure 1 , Figure 8 and Figure 9 As shown, some fan-out traces 120 and touch signal lines 310 in the display panel 10 are not overlapped along the thickness direction of the display panel 10. Therefore, these fan-out traces 120 can all be set on the same layer as the touch signal lines 310.

[0060] For details, please refer to Figure 2 and Figure 10 As shown in the figure, the touch driving signal line 310a in the touch signal line 310 is set in the first touch metal layer TM1 as an example. Along the thickness direction of the display panel 10, the overlapping portion of the fan-out trace 120 and the touch driving signal line 310a can be set in the film layer where the first metal layer M1 is located; along the thickness direction of the display panel 10, the non-overlapping portion of the fan-out trace 120 and the touch driving signal line 310a can be set in the first touch metal layer TM1. (Reference) Figure 2 and Figure 11 As shown in the figure, the touch driving signal line 310a in the touch signal line 310 is set in the first touch metal layer TM1 as an example. Along the thickness direction of the display panel 10, the overlapping portion of the fan-out trace 120 and the touch driving signal line 310a can be set in the film layer where the second metal layer Mc is located; along the thickness direction of the display panel 10, the non-overlapping portion of the fan-out trace 120 and the touch driving signal line 310a can be set in the first touch metal layer TM1. (Reference) Figure 2 and Figure 12As shown in the figure, the touch driving signal line 310a in the touch signal line 310 is set in the second touch metal layer TM2 as an example. Along the thickness direction of the display panel 10, the overlapping portion of the fan-out trace 120 and the touch driving signal line 310a can be set in the film layer where the first metal layer M1 is located; along the thickness direction of the display panel 10, the non-overlapping portion of the fan-out trace 120 and the touch driving signal line 310a can be set in the second touch metal layer TM2. (Reference) Figure 2 and Figure 13 As shown in the figure, the touch driving signal line 310a in the touch signal line 310 is set in the second touch metal layer TM2 as an example. Along the thickness direction of the display panel 10, the overlapping portion of the fan-out trace 120 and the touch driving signal line 310a can be set in the film layer where the second metal layer Mc is located; along the thickness direction of the display panel 10, the non-overlapping portion of the fan-out trace 120 and the touch driving signal line 310a can be set in the second touch metal layer TM2. Therefore, combined with Figure 2 , Figures 10 to 13 As shown, along the thickness direction of the display panel 10, the portion of the fan-out trace 120 that does not overlap with the touch signal line 310 can be set on the same layer as the touch signal line 310.

[0061] Further reference Figures 1 to 13 As shown, the touch signal line 310 can be disposed on the film layer where the first touch metal layer TM1 is located and / or on the film layer where the second touch metal layer TM2 is located, wherein the film layer ductility of the first touch metal layer TM1 and the second touch metal layer TM2 is better than that of the first metal layer M1 and the second metal layer Mc, etc. Similarly, the touch electrode 320 can be disposed on the film layer where the first touch metal layer TM1 is located and / or on the film layer where the second touch metal layer TM2 is located. Therefore, disposing of a portion of the fan-out trace 120 on the film layer where the first touch metal layer TM1 is located or on the film layer where the second touch metal layer TM2 is located, that is, disposing of at least a portion of the fan-out trace 120 on the same layer as the touch sub-section, can improve the structural stability of the fan-out trace 120, can ensure the signal transmission effect of the fan-out trace 120, and can ensure the display effect of the display panel 10.

[0062] Furthermore, the sheet resistance of the film layers containing the first touch metal layer TM1 and the second touch metal layer TM2 is generally lower than that of the film layers containing the first metal layer M1 and the second metal layer Mc. Therefore, adjusting some of the fan-out traces 120 originally located in the first metal layer M1 and the second metal layer Mc to the first touch metal layer TM1 or to the second touch metal layer TM2 can effectively reduce the signal transmission loss in the fan-out traces 120, thereby improving the data signal transmission effect and ensuring the display effect of the display panel 10.

[0063] In summary, the embodiments of this application provide a display panel in which at least a portion of the fan-out traces are disposed on the same layer as the touch sub-section. On the one hand, this can improve the utilization rate of some film layers in the display panel, providing space for other traces. On the other hand, since the extensibility of signal lines and other structures disposed on different film layers varies, disposing at least a portion of the fan-out traces on the same layer as the touch sub-section can also improve the structural stability of the fan-out traces, ensuring the signal transmission effect of the fan-out traces and thus ensuring the display effect of the display panel.

Figure 3 , Figures 14 to 20 As shown, the touch structure 300 includes a first touch sub-section 300a and a second touch sub-section 300b disposed in different layers; the fan-out routing line 120 includes a first fan-out routing line 121 and a second fan-out routing line 122, at least a portion of the first fan-out routing line 121 is disposed in the same layer as the first touch sub-section 300a, and at least a portion of the second fan-out routing line 122 is disposed in the same layer as the second touch sub-section 300b.

[0065] The touch structure 300 includes a first touch sub-section 300a and a second touch sub-section 300b disposed in different layers, combined with Figure 3As shown, the first touch sub-section 300a and the second touch sub-section 300b can be respectively disposed on the film layer where the first touch metal layer TM1 is located and the film layer where the second touch metal layer TM2 is located. Specifically, the first touch sub-section 300a may include a portion of the touch signal lines 310 and / or a portion of the touch electrodes 320; similarly, the second touch sub-section 300b may include a portion of the touch signal lines 310 and / or a portion of the touch electrodes 320. For example, the first touch sub-section 300a is located on the film layer where the first touch metal layer TM1 is located, and the second touch sub-section 300b is located on the film layer where the second touch metal layer TM2 is located. That is, the first touch sub-section 300a can be understood as the touch signal lines 310 and / or touch electrodes 320 located on the first touch metal layer TM1, and the second touch sub-section 300b can be understood as the touch signal lines 310 and / or touch electrodes 320 located on the second touch metal layer TM2. by Figure 15 For example, the touch signal line 310 in the second touch metal layer TM2 is connected through the bridging portion 330 in the first touch metal layer TM1. Here, the bridging portion 330 in the first touch metal layer TM1 can be the first touch sub-section 300a, and the touch signal line 310 in the second touch metal layer TM2 can be the second touch sub-section 300b.

[0066] Furthermore, the fan-out trace 120 includes a first fan-out trace 121 and a second fan-out trace 122, wherein at least a portion of the first fan-out trace 121 and at least a portion of the second fan-out trace 122 are disposed on different layers. Specifically, at least a portion of the first fan-out trace 121 can be disposed on the same layer as the first touch sub-section 300a, and at least a portion of the second fan-out trace 122 can be disposed on the same layer as the second touch sub-section 300b. In this way, depending on the different placement positions of the fan-out traces 120, they can be disposed on the same layer as different touch sub-sections, further improving the film layer utilization rate of the display panel 10 and ensuring flexible arrangement of the fan-out traces 120 in the display panel 10.

[0067] For example, refer to Figures 14 to 20 As shown, the example uses the bridging portion 330 as the first touch sub-section 300a and the touch signal line 310 as the second touch sub-section 300b. (Refer to...) Figures 14 to 17 , Figure 18 As shown, at least a portion of the first outgoing trace 121 is disposed on the same layer as the bridging portion 330, therefore at least a portion of the first outgoing trace 121 is disposed on the same layer as the first touch sub-section 300a. Wherein, Figure 17 The example is given by setting part of the first sector outgoing trace 121 at the film layer where the first metal layer M1 is located. Figure 18The example illustrates this by setting part of the traces in the first sector 121 at the film layer where the second metal layer Mc is located.

[0068] For example, refer to Figures 14 to 20 As shown, the example uses the bridging portion 330 as the first touch sub-section 300a and the touch signal line 310 as the second touch sub-section 300b. (Refer to...) Figures 14 to 16 , Figure 19 and Figure 20 As shown, the second outgoing trace 122 is disposed on the same layer as the touch signal line 310, therefore the second outgoing trace 122 is disposed on the same layer as the second touch sub-section 300b. Figure 19 The example is given by setting part of the second sector outgoing trace 122 at the film layer where the first metal layer M1 is located. Figure 20 The example illustrates how some of the traces in the second sector 122 are located at the film layer where the second metal layer Mc is located.

[0069] Furthermore, the configuration of the first and second outgoing cables in the display panel can be varied, as detailed below:

[0070] Figure 21 This is a top view schematic diagram of the first type of fan-out routing provided in the embodiments of this application, with reference to... Figure 14 and Figure 21 As shown, the sheet resistance of the first touch sub-section 300a is greater than the sheet resistance of the second touch sub-section 300b; the extension length of at least a portion of the first fan-out trace 121 is less than the extension length of at least a portion of the second fan-out trace 122.

[0071] Specifically, the sheet resistance of the first touch sub-section 300a is greater than that of the second touch sub-section 300b, meaning that the sheet resistance of the film layer containing the first touch sub-section 300a is greater than that of the film layer containing the second touch sub-section 300b. Therefore, the sheet resistance of the first fan-out trace 121, which is disposed on the same layer as the first touch sub-section 300a, is greater than that of the second fan-out trace 122, which is disposed on the same layer as the second touch sub-section 300b.

[0072] Furthermore, in order to ensure the balance of data signal transmission in the first outgoing line 121 and the second outgoing line 122, the extension lengths of the first outgoing line 121 and the second outgoing line 122 can be adjusted according to the difference in sheet resistance of the film layers in which the first outgoing line 121 and the second outgoing line 122 are located.

[0073] Specifically, in comparison Figure 21In the first outgoing trace 121 and the second outgoing trace 122, the extension length L1 of at least a portion of the first outgoing trace 121 is adjusted to be less than the extension length L2 of at least a portion of the second outgoing trace 122, where L1 < L2, and L1 and L2 are positive numbers. The portion of the first outgoing trace 121 used for length comparison with the second outgoing trace 122 can be understood as a portion of the first outgoing trace 121 that is disposed on the same layer as the first touch sub-section 300a. Similarly, the portion of the second outgoing trace 122 used for length comparison with the first outgoing trace 121 can be understood as a portion of the second outgoing trace 122 that is disposed on the same layer as the second touch sub-section 300b. By adjusting the extension length of the first outgoing trace 121 and the second outgoing trace 122, the resistance difference between the first outgoing trace 121 and the second outgoing trace 122 caused by the difference in sheet resistance can be compensated, ensuring that the data signal transmitted to the first outgoing trace 121 and the data signal transmitted to the second outgoing trace 122 are balanced, thereby ensuring the overall display effect of the display panel 10.

[0074] For example, refer to Figure 14 As shown, the second outgoing trace 122, which has a relatively longer extension length, can be placed in the two side areas of the display panel 10, while the first outgoing trace 121, which has a relatively shorter extension length, can be placed in the central area of ​​the display panel 10. This provides flexibility in the arrangement of the first outgoing trace 121 and the second outgoing trace 122. Figure 14 This application only shows one arrangement and can be adapted to meet actual needs. It does not impose any specific limitations on this arrangement.

[0075] Figure 22 This is a top view schematic diagram of the second type of fan-out routing provided in the embodiments of this application, for reference. Figure 22 As shown, the sheet resistance of the first touch sub-section 300a is greater than the sheet resistance of the second touch sub-section 300b; the line width of at least a portion of the first fan-out trace 121 is greater than the line width of at least a portion of the second fan-out trace 122.

[0076] Furthermore, in order to ensure the balance of data signal transmission in the first outgoing line 121 and the second outgoing line 122, the linewidths of the first outgoing line 121 and the second outgoing line 122 can be adjusted according to the difference in sheet resistance of the film layers in which the first outgoing line 121 and the second outgoing line 122 are located.

[0077] Specifically, in comparison Figure 22The first outgoing trace 121 and the second outgoing trace 122 are configured such that the line width S1 of the first outgoing trace 121 is greater than the line width S2 of the second outgoing trace 122, where S1 > S2, and S1 and S2 are positive numbers. The portion of the first outgoing trace 121 used for line width comparison with the second outgoing trace 122 can be understood as the portion of the first outgoing trace 121 that is on the same layer as the first touch sub-section 300a. Similarly, the portion of the second outgoing trace 122 used for line width comparison with the first outgoing trace 121 can be understood as the portion of the second outgoing trace 122 that is on the same layer as the second touch sub-section 300b. By adjusting the trace width of the first outgoing trace 121 and the trace width of the second outgoing trace 122, the resistance difference between the first outgoing trace 121 and the second outgoing trace 122 caused by the difference in sheet resistance can be compensated, ensuring that the data signal transmitted to the first outgoing trace 121 and the data signal transmitted to the second outgoing trace 122 are balanced, thereby ensuring the overall display effect of the display panel 10.

[0078] Figure 23 This is a schematic diagram of the structure of the fourth type of display panel provided in the embodiments of this application. Figure 24 yes Figure 23 An enlarged schematic diagram of region H in the middle, for reference. Figure 23 and Figure 24 As shown, the first outgoing line 121 and the second outgoing line 122 are alternately arranged along the first direction X1, and the first direction X1 intersects the extension direction of the outgoing line 120.

[0079] Among them, reference Figure 23 and Figure 24 As shown, multiple first-side outgoing cables 121 are arranged along a first direction X1, and multiple second-side outgoing cables 122 are arranged along the first direction X1. Specifically, along the first direction X1, the first-side outgoing cables 121 and second-side outgoing cables 122 are arranged alternately. This can also be understood as follows: along the first direction X1, a second-side outgoing cable 122 is positioned between two adjacent first-side outgoing cables 121, and a first-side outgoing cable 121 is positioned between two adjacent second-side outgoing cables 122.

[0080] Furthermore, the first fan-out trace 121 and the second fan-out trace 122 are located on different film layers. Therefore, in the area where the first fan-out trace 121 and the second fan-out trace 122 are located, adjacent fan-out traces 120 are located on different film layers. This reduces the parasitic capacitance between adjacent fan-out traces 120, ensuring the stability and reliability of signal transmission on the first fan-out trace 121 and the second fan-out trace 122. At the same time, adjusting the disparate layer arrangement of adjacent fan-out traces 120 also ensures the spacing between the fan-out traces 120, ensuring the regularity of the fan-out traces 120 in the display panel 10, and ensuring the overall structural regularity of the display panel 10.

[0081] Figure 25 This is a schematic diagram of the structure of the fifth type of display panel provided in the embodiments of this application. Figure 26 yes Figure 25 A schematic diagram of the first type of section along section line I-I', see reference. Figure 25 and Figure 26 As shown, the touch structure 300 includes a first touch sub-section 300a and a second touch sub-section 300b disposed in different layers; the fan-out trace 120 includes a third fan-out trace 123, which includes a first fan-out trace section 1231 and a second fan-out trace section 1232 disposed in different layers; along the thickness direction of the display panel 10, the first fan-out trace section 1231 and the second fan-out trace section 1232 overlap and are electrically connected; the first fan-out trace section 1231 is disposed in the same layer as the first touch sub-section 300a, and the second fan-out trace section 1232 is disposed in the same layer as the second touch sub-section 300b.

[0082] The touch structure 300 includes a first touch sub-section 300a and a second touch sub-section 300b disposed in different layers, combined with Figure 3 As shown, the first touch sub-section 300a and the second touch sub-section 300b can be respectively disposed on the film layer where the first touch metal layer TM1 is located and the film layer where the second touch metal layer TM2 is located.

[0083] Furthermore, the fan-out routing 120 includes a third fan-out routing 123, wherein the third fan-out routing 123 includes a first fan-out routing portion 1231 and a second fan-out routing portion 1232 disposed on different layers. (See reference) Figure 26As shown, the first and second outgoing traces 1231 and 1232, which are arranged in different layers, overlap in at least a portion along the thickness direction of the display panel 10, and the overlapping areas of the first and second outgoing traces 1231 and 1232 are electrically connected. Thus, the first and second outgoing traces 1231 and 1232 are essentially connected in parallel, which effectively reduces the resistance of the third outgoing trace 123, effectively improves the data signal transmission effect in the third outgoing trace 123, and ensures the display effect of the display panel 10.

[0084] For details, please refer to Figure 26 As shown, specifically, the first fan-out trace portion 1231 can be arranged on the same layer as the first touch sub-section 300a, and the second fan-out trace portion 1232 can be arranged on the same layer as the second touch sub-section 300b. For example, the first touch sub-section 300a is located on the film layer containing the first touch metal layer TM1, and the second touch sub-section 300b is located on the film layer containing the second touch metal layer TM2. This allows different positions in the third fan-out trace 123 to be arranged on the same layer as different touch structures 300. While reducing the resistance of the third fan-out trace 123, it also improves the film layer utilization rate of the display panel 10, ensuring flexible arrangement of the fan-out traces 120 in the display panel 10.

[0085] Figure 27 This is a schematic diagram of the structure of the sixth type of display panel provided in the embodiments of this application. Figure 28 yes Figure 27 A schematic diagram of the first type of cross-section along section line J-J'. Figure 29 yes Figure 27 A schematic diagram of the second type of cross-section along section line J-J'. Figure 30 yes Figure 27 A schematic diagram of the third type of cross-section along section line J-J'. Figure 31 yes Figure 27 A schematic diagram of the fourth section along section line J-J', see reference. Figures 27 to 31As shown, the display panel 10 also includes a display area AA and a non-display area NA, with the non-display area NA located on at least one side of the display area AA. The non-display area NA includes a first fan-out area 1001, a bend area 1002, and a second fan-out area 1003. The first fan-out area 1001 is located on the side of the bend area 1002 closer to the display area AA, and the second fan-out area 1003 is located on the side of the bend area 1002 away from the display area AA. The fan-out trace 120 includes a third fan-out trace portion 1241, a second fan-out trace portion 1241, and a third fan-out trace portion 1242. The fourth outgoing cable section 1242 and the fifth outgoing cable section 1243 are electrically connected to the third outgoing cable section 1241 and the fifth outgoing cable section 1243. The third outgoing cable section 1241 is located in the first outgoing area 1001, the fourth outgoing cable section 1242 is located in the bending area 1002, and the fifth outgoing cable section 1243 is located in the second outgoing area 1003. At least the fifth outgoing cable section 1243 is arranged on the same layer as the touch sub-section.

[0086] Among them, reference Figure 27 As shown, the display panel 10 includes a display area AA. Light-emitting elements (not specifically shown) disposed in the display area AA are used to realize the display function of the display panel 10. Touch electrodes 320 disposed in the display area AA are used to realize the touch function of the display panel 10. The non-display area NA of the display panel 10 is located on at least one side of the display area AA. The arrangement of the display area AA and the non-display area NA in the display panel 10 is diverse. Figure 27 Only one example is shown for illustration.

[0087] Further reference Figure 27 As shown, the non-display area NA includes a first fan-out area 1001, a bend area 1002, and a second fan-out area 1003. The first fan-out area 1001 is located on the side of the bend area 1002 closer to the display area AA, and the second fan-out area 1003 is located on the side of the bend area 1002 away from the display area AA. The driver chip 200 can be located on the side of the second fan-out area 1003 away from the bend area 1002. Thus, the fan-out trace 120, electrically connected to the data signal line 110, sequentially passes through the first fan-out area 1001, the bend area 1002, and the second fan-out area 1003.

[0088] For details, please refer to Figures 27 to 31 As shown, the fan-out trace 120 includes a third fan-out trace portion 1241 located in the first fan-out area 1001, a fourth fan-out trace portion 1242 located in the bend area 1002, and a fifth fan-out trace portion 1243 located in the second fan-out area 1003. The fourth fan-out trace portion 1242 is electrically connected to the third fan-out trace portion 1241 and the fifth fan-out trace portion 1243 to ensure the stability of signal transmission between the driver chip 200 and the data signal line 110.

[0089] At least the fifth fan-out trace portion 1243 is disposed on the same layer as the touch sub-section. For example, the fifth fan-out trace portion 1243 is disposed on the same layer as a portion of the touch signal lines 310. Along the thickness direction of the display panel 10, the fifth fan-out trace portion 1243 located in the second fan-out area 1003 is disposed on the same layer as the touch signal lines 310 without overlapping. To improve the space utilization of the film layer and ensure the extensibility of the fan-out trace 120, the fifth fan-out trace portion 1243 can be disposed on the same layer as the touch signal lines 310. For example, refer to... Figure 28 and Figure 30 The example illustrates this by having both the fifth sector outgoing trace 1243 and the touch signal line 310 located in the same film layer as the first touch metal layer TM1; see reference. Figure 29 and Figure 31 The example is given by setting both the fifth fan-out routing section 1243 and the touch signal line 310 in the film layer where the second touch metal layer TM2 is located.

[0090] Continue to refer to Figure 30 and Figure 31 As shown, the fourth fan-out wiring section 1242 is set on the same layer as the touch sub-section.

[0091] The fourth outgoing trace section 1242 can be arranged on the same layer as the touch sub-section. Specifically, the fourth outgoing trace section 1242 can be arranged on the same layer as the touch signal line 310, or the fourth outgoing trace section 1242 can be arranged on the same layer as the touch electrode 320. For example, refer to Figure 30 and Figure 31 As shown, along the thickness direction of the display panel 10, the fourth fan-out trace portion 1242 located in the bending area 1002 does not overlap with the touch signal line 310. Therefore, the fourth fan-out trace portion 1242 can also be arranged in the same layer as the touch signal line 310, further improving the space utilization of the film layer. The touch signal line 310 generally adopts a titanium-aluminum-titanium structure and has good ductility. Therefore, the fourth fan-out trace portion 1242 and the fifth fan-out trace portion 1243, arranged in the same layer as the touch signal line 310, also have good ductility, which can improve the structural stability of the fan-out trace 120.

[0092] Furthermore, the fourth fan-out trace 1242 located in the bending area 1002 and the fifth fan-out trace 1243 located in the second fan-out area 1003 are arranged on the same layer. To ensure that the fourth fan-out trace 1242 and the fifth fan-out trace 1243 are electrically connected, they do not need to be connected across layers. Therefore, from the perspective of the manufacturing process of the display panel 10, arranging the fourth fan-out trace 1242 and the fifth fan-out trace 1243 on the same layer can also reduce one line-changing process and reduce the manufacturing cost of the display panel 10.

[0093] Continue to refer to Figure 28 and Figure 29 As shown, the fourth fan-out routing section 1242 is disposed on a different layer from the touch sub-section; the fourth fan-out routing section 1242 is located on the side of the touch signal line 310 near the bending neutral surface of the bending area 1002.

[0094] The fourth fan-out routing section 1242 is located in the bending area 1002, where the routing line bends synchronously with the film structure. Part of the touch substructure can also be located in the bending area 1002, allowing adjustment of the film layer positions of the fourth fan-out routing section 1242 and the touch signal line 310 to ensure overall structural stability. The touch substructure can be illustrated using the touch signal line 310 as an example. For details, refer to... Figure 27 , Figure 28 and Figure 29 As shown, the fourth fan-out routing section 1242 is located in the bending area 1002, and the fourth fan-out routing section 1242 and the touch signal line 310 do not overlap along the thickness direction of the display panel 10. Therefore, the setting of the touch signal line 310 does not affect the fourth fan-out routing section 1242, and the position setting of the fourth fan-out routing section 1242 is flexible.

[0095] For details, please refer to Figure 28 and Figure 29 As shown, the fourth fan-out trace portion 1242 can be located on the side of the touch signal line 310 near the bending neutral surface of the bending area 1002, for example, in the film layer where the fourth metal layer M3 is located. The fourth metal layer M3 is located on one side of the bending neutral surface of the bending area 1002. The bending neutral surface of the bending area 1002 can be understood as a virtual intermediate surface of the display panel 10 within the bending area 1002, where it is neither stretched nor compressed, thus balancing the stress generated during bending. Since the fourth metal layer M3 is closer to the bending neutral surface of the bending area 1002 than the film layer where the touch signal line 310 is located, the fourth metal layer M3 can better prevent crack formation, thereby ensuring the structural stability of the fourth fan-out trace portion 1242, which in turn ensures the structural stability of the fan-out trace 120, guarantees the reliability of data signal transmission, and ensures the display effect of the display panel 10.

[0096] Figure 32 yes Figure 27 A schematic diagram of the first type of cross-section along section line K-K', see reference. Figure 27 and Figure 32As shown, the touch sub-section includes a touch signal line 310. The touch signal line 310 includes a first touch signal line section 313 located in the bending area 1002 and a second touch signal line section 314 located in the second fan-out area 1003. The first touch signal line section 313 and the second touch signal line section 314 are electrically connected. The first touch signal line section 313 and the second touch signal line section 314 are arranged on the same layer.

[0097] Further reference Figure 27 and Figure 32 As shown, the touch signal line 310 includes a first touch signal line portion 313 and a second touch signal line portion 314 that are electrically connected. The first touch signal line portion 313 is located in the bending area 1002, and the second touch signal line portion 314 is located in the second fan-out area 1003. This can be understood as the first touch signal line portion 313 and the second touch signal line portion 314 being two routing portions of the touch signal line 310 extending to the bending area 1002 and extending to the second fan-out area 1003, respectively.

[0098] For details, please refer to Figure 32 As shown, the first touch signal line portion 313 and the second touch signal line portion 314 can be arranged on the same layer. In this way, when the touch signal line 310 extends to different areas, that is, when it extends to the bending area 1002 and the second fan-out area 1003, it does not need to be changed, which can reduce the manufacturing difficulty of the display panel 10. Figure 32 The example illustrates this by having both the first touch signal line portion 313 and the second touch signal line portion 314 disposed on the same film layer as the second touch metal layer TM2. Furthermore, placing the first touch signal line portion 313 and the second touch signal line portion 314 on the same layer can improve the space utilization of the film layer, thereby providing sufficient space for other wiring and other installations.

[0099] Figure 33 yes Figure 27 A schematic diagram of the second type of section along section line K-K', see reference. Figure 27 and Figure 33 As shown, the touch sub-section includes a touch signal line 310. The touch signal line 310 includes a first touch signal line section 313 located in the bending area 1002 and a second touch signal line section 314 located in the second fan-out area 1003. The first touch signal line section 313 and the second touch signal line section 314 are electrically connected. The first touch signal line section 313 and the second touch signal line section 314 are disposed in different layers, and the first touch signal line section 313 is located on the side of the second touch signal line section 314 near the bending neutral surface of the bending area 1002.

[0100] Further reference Figure 33As shown, the first touch signal line portion 313 and the second touch signal line portion 314 can be arranged in different layers, demonstrating the flexibility of the arrangement of the touch signal line 310. Specifically, the first touch signal line portion 313 is located in the bending area 1002. In the actual display panel 10, the traces arranged in the bending area 1002 need to be bent. Therefore, by placing the first touch signal line portion 313 on the side close to the bending neutral surface of the bending area 1002, for example, at the film layer where the fourth metal layer M3 is located, it is possible to prevent the touch signal line 310 from cracking in the bending area 1002, ensuring the structural stability of the touch signal line 310, thereby ensuring the reliability of touch signal transmission and the touch effect of the display panel 10.

[0101] Figure 34 This is a schematic diagram of the structure of the seventh type of display panel provided in the embodiments of this application. Figure 35 This is a schematic diagram of a multiplexing circuit provided in an embodiment of this application, with reference to... Figure 34 and Figure 35 As shown, the display panel 10 also includes a multiplexing circuit 400, which includes multiple multiplexing units 410. Each multiplexing unit 410 includes an input terminal 410a and an output terminal 410b. The input terminal 410a is electrically connected to the driver chip 200, and the output terminal 410b is electrically connected to at least two fan-out traces 120.

[0102] The display panel 10 also includes a multiplexing circuit 400, which can be understood as a combined logic circuit. One end of the multiplexing circuit 400 is electrically connected to the driver chip 200, and the other end is electrically connected to multiple fan-out traces 120. For example... Figure 35As shown, the multiplexing circuit 400 may include multiple multiplexing units 410, each multiplexing unit 410 including an input terminal 410a, an output terminal 410b, and a control terminal 410c. The display panel 10 also includes multiple clock signal lines CK, which are electrically connected to the control terminal 410c of the multiplexing unit 410, equivalent to the clock signal lines CK being electrically connected to the control terminal of the multiplexing unit 410. The driver chip 200 is electrically connected to the input terminal 410a, meaning that when the multiplexing unit 410 is turned on, the data signal provided by the driver chip 200 can be transmitted to the multiplexing unit 410. At least two fan-out traces 120 are electrically connected to the output terminal 410b, meaning that the multiplexing unit 410 can transmit data signals to the multiple fan-out traces 120. In this way, the same multiplexing unit 410 can transmit the same data signal input from the same input terminal 410a to different output terminals 410b, and then to different data signal lines 110, under the action of the clock signal provided by the clock signal line CK. While ensuring normal data signal transmission, the number of input terminals 410a can be reduced, thereby reducing the number of pins in the driver chip 200 and reducing the design difficulty of the driver chip 200.

[0103] The multiplexing circuit 400 can be located in either the first fan-out zone 1001 or the second fan-out zone 1003. Figure 34 The example illustrates how the multiplexing circuit 400 is positioned in the second fan-out zone 1003. This demonstrates the flexibility in the placement of the multiplexing circuit 400. Specifically, in conjunction with... Figure 34 and Figure 35 As shown, the multiplexing circuit 400 can be set in the first fan-out area 1001 or the second fan-out area 1003. Therefore, at least some of the fan-out traces 120 are set in the same layer as the touch signal lines 310. Since the sheet resistance of the film layer where the touch signal lines 310 are located is relatively small, setting some of the fan-out traces 120 in the film layer with low sheet resistance can effectively reduce the loss of the fan-out traces 120 during transmission, which is conducive to ensuring the transmission effect of data signals and further improving the display effect of the display panel 10.

[0104] Figure 36 This is a cross-sectional schematic diagram of another film layer structure in a display panel provided in this application embodiment, for reference. Figure 1 , Figure 2 , Figure 14 , Figure 23 , Figure 25 , Figure 27 , Figure 34 and Figure 36As shown, the display panel 10 also includes an array substrate 500 and a packaging structure 600. The data signal line 110, the fan-out trace 120 and the driver chip 200 are all disposed on the array substrate 500; the packaging structure 600 is located on the side of the touch structure 300 close to the array substrate 500.

[0105] For details, please refer to Figure 36 As shown, the display panel 10 includes an array substrate 500 and a packaging structure 600, with the packaging structure 600 located on the side of the touch structure 300 near the array substrate 500. Wherein, combined with Figure 1 , Figure 2 , Figure 14 , Figure 23 , Figure 25 , Figure 27 , Figure 34 and Figure 36 As shown, the data signal line 110, fan-out trace 120, and driver chip 200 are all disposed on the array substrate 500, and the array substrate 500 also includes a circuit structure 510 and a light-emitting element 520, etc. It should be noted that the circuit structure 510 in the array substrate 500 may include a border circuit and a pixel circuit, and the circuit structure 510 includes at least one transistor. Figure 36 The pixel circuit is used as an example for illustration.

[0106] Combination Figure 36 As shown, the addition of an encapsulation structure 600 to the display panel 10 can better ensure the structural stability of the display panel 10. The encapsulation structure 600 is located between the touch structure 300 and the array substrate 500. The encapsulation structure 600 includes a first encapsulation layer 601, a second encapsulation layer 602, and a third encapsulation layer 603. The encapsulation structure 600 includes an organic film layer, which helps improve the overall flatness of the display panel 10. Optionally, the first encapsulation layer 601 and the third encapsulation layer 603 can be organic film layers, and the second encapsulation layer 602 can be an inorganic film layer; alternatively, the first encapsulation layer 601 and the third encapsulation layer 603 can be inorganic film layers, and the second encapsulation layer 602 can be an organic film layer. The touch structure 300 and the array substrate 500 are disposed on both sides of the encapsulation structure 600 along the thickness direction of the display panel 10. This increases the spacing between the touch structure 300 and the array substrate 500, which can reduce some interference that may occur between the touch structure 300 and the array substrate 500, thereby better ensuring the display function and touch function of the display panel 10.
