Description

Technical Field

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

[0002] Existing display devices typically include touch components, which often serve as an input device within the display device. For example, in a display device, a user can input information by pressing or touching a touch sensor while viewing an image displayed on the screen.

[0003] In relevant touch display panels, the touch components include touch electrodes located in the display area and touch traces located in the non-display area. The touch traces connect to the circuit board to transmit touch signals between the circuit board and the touch electrodes. Since the touch traces typically extend directly from the touch electrodes towards the circuit board, the arrangement of touch traces in the non-display area is uneven. To improve the uniformity of the wiring, virtual electrical blocks are arranged around the touch electrodes in the non-display area. These virtual electrical blocks easily accumulate charge, which can significantly affect the lifespan of the touch electrode blocks. Summary of the Invention

[0004] This application provides a display panel and display device, which aim to improve the service life of touch components.

[0005] An embodiment of the first aspect of this application provides a display panel having a display area and a non-display area. The display panel includes: a substrate; a touch component disposed on the substrate; the touch component including touch electrodes located in the display area and touch leads connected to the touch electrodes and located in the non-display area; and a circuit board connected to the substrate in the non-display area, with the touch leads connected between the touch electrodes and the circuit board. The non-display area has a cutting trajectory surrounding at least a portion of the display area, and at least a portion of the touch leads includes a first redundant winding segment and a connecting segment. The first redundant winding segment extends in a direction away from the circuit board and fills the space between the cutting trajectory and the display area, and the connecting segment connects the first redundant winding segment and the circuit board.

[0006] An embodiment of the second aspect of this application also provides a display device, including the display panel described above.

[0007] In the display panel provided in this application embodiment, the display panel includes a substrate and a touch component and a circuit board disposed on the substrate. The touch electrodes of the touch component are connected to the circuit board through touch leads, enabling the transmission of touch signals between the circuit board and the touch electrodes. At least a portion of the touch leads includes a first redundant winding segment and a connecting segment, and the first redundant winding segment extends in a direction away from the circuit board, allowing the first redundant winding segment to fill the blank space between the cutting trajectory and the display area that is not filled by the connecting segment, ensuring the uniformity of the winding in the non-display area. The first redundant winding segment is connected between the touch electrode block and the circuit board, allowing the static electricity on the first redundant winding segment to be released, thus improving the impact of static electricity release on the touch component. Therefore, by providing a first redundant winding segment on the touch trace, this application embodiment can omit the arrangement of virtual electrode blocks, not only ensuring the uniformity of the wiring in the non-display area but also improving the impact of static electricity release on the lifespan of the touch component.

However, it will be apparent to those skilled in the art that this application can be implemented without requiring some of these specific details.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the embodiments of this application. It should also be noted in the description of this application that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0033] To better understand this application, the following will be combined with... Figures 1 to 10 The display panel and display device according to the embodiments of this application will be described in detail.

[0034] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a display panel 10 provided in the first aspect embodiment of this application. Figure 2 yes Figure 1 A magnified schematic diagram of the structure at point I in the middle.

[0035] like Figure 1 and Figure 2 As shown, the display panel 10 provided in the first aspect of this application has a display area AA and a non-display area NA. The display panel 10 includes: a substrate 100; a touch component 200 disposed on the substrate 100; the touch component 200 includes a touch electrode 210 located in the display area AA and a touch lead 220 connected to the touch electrode 210 and located in the non-display area NA; and a circuit board 300 connected to the substrate 100 in the non-display area NA, with the touch lead 220 connected between the touch electrode 210 and the circuit board 300. The non-display area NA has a cutting trajectory 400 surrounding at least a portion of the display area AA. At least a portion of the touch lead 220 includes a first redundant winding segment 221 and a connecting segment 222. At least a portion of the first redundant winding segment 221 extends in a direction away from the circuit board 300 and fills the space between the cutting trajectory 400 and the display area AA. The connecting segment 222 connects the first redundant winding segment 221 and the circuit board 300.

[0036] In the display panel 10 provided in this embodiment, the display panel 10 includes a substrate 100 and a touch component 200 and a circuit board 300 disposed on the substrate 100. The touch electrode 210 of the touch component 200 is connected to the circuit board 300 through a touch lead 220, so that touch signals can be transmitted between the circuit board 300 and the touch electrode 210. At least a portion of the touch lead 220 includes a first redundant winding segment 221 and a connecting segment 222, and the first redundant winding segment 221 extends in a direction away from the circuit board 300, so that the first redundant winding segment 221 can fill the blank space between the cutting trajectory 400 and the display area AA that is not filled by the connecting segment 222, ensuring the uniformity of the winding in the non-display area NA. The first redundant winding segment 221 is connected between the touch electrode 210 block and the circuit board 300, so that the static electricity on the first redundant winding segment 221 can be released, which can improve the impact of static electricity release on the touch component 200.

[0037] Furthermore, by lengthening the wiring length of certain touch leads 220 and setting a first redundant winding segment 221 on the touch leads 220 to fill the blank area between the cutting trajectory 400 and the display area AA, the arrangement of virtual electrode blocks can be omitted. This not only ensures the uniformity of wiring in the non-display area NA, but also improves the impact of electrostatic discharge on the lifespan of the touch component 200.

[0038] The cutting trajectory 400 refers to the cutting trajectory 400 when the display panel 10 is cut. The first redundant winding segment 221 is arranged between the cutting trajectory 400 and the display area AA. When the display panel 10 is cut, the first redundant winding segment 221 can be prevented from being cut and affecting the transmission of the touch component 200 signal.

[0039] In some alternative embodiments, please continue to refer to Figure 1 and Figure 2 The display panel 10 also includes a grounding component 500 disposed on the substrate 100. The grounding component 500 includes a grounding wire 510 disposed in the non-display area NA and surrounding at least a portion of the display area AA. The cutting trajectory 400 is located on the side of the grounding wire 510 away from the display area AA. At least a portion of the first redundant winding segment 221 extends in a direction away from the circuit board 300 and fills the space between the grounding wire 510 and the display area AA.

[0040] In these alternative embodiments, the first redundant winding segment 221 is located between the grounding wire 510 and the display area AA, making the distance between the first redundant winding segment 221 and the display area AA closer. This can not only prevent the first redundant winding segment 221 from being cut, but also better improve the uniformity of the wiring in the non-display area NA.

[0041] Optionally, the grounding wire 510 is U-shaped and has two first grounding segments 511 extending along the second direction Y and arranged side by side along the first direction X on both sides of the display area AA, a second grounding segment 512 connecting the two first grounding segments 511, and an irregularly shaped grounding segment 513 connecting the first grounding segments 511 and the second grounding segment 512. The second grounding segment 512 extends along the first direction X and is separately located from the circuit board 300 on opposite sides of the display area AA in the second direction Y. At least a portion of the first redundant winding segment 221 is located between the irregularly shaped grounding segment 513 and the display area AA.

[0042] Typically, the touch leads 220 located on both sides of the display area AA in the first direction X and the second direction Y extend directly toward the circuit board 300, which results in a blank area between the irregular ground section 513 and the display area AA. The first redundant winding section 221 located in this area can better improve the uniformity of the wiring.

[0043] Optional, please continue reading Figure 1 and Figure 2 The display panel 10 also includes a packaging structure, which includes, for example, a packaging edge 400a surrounding the display area AA. The cutting trajectory 400 is located on the side of the packaging edge 400a away from the display area AA. The first redundant winding segment 221 is located between the packaging edge 400a and the display area AA. On the one hand, it can prevent the first redundant winding segment 221 from being cut. On the other hand, it enables the packaging structure to provide protection for the touch lead 220. Figure 1 and Figure 2 The dotted line in the middle indicates the package edge 400a.

[0044] The encapsulation structure can be a thin-film encapsulation including stacked encapsulation layers, with encapsulation edge 400a being the edge of the encapsulation layer. Alternatively, the encapsulation structure can be a glass powder encapsulation, including a cover plate and a sealing adhesive, with encapsulation edge 400a being the area where the sealing adhesive is located.

[0045] Optionally, there are multiple ways to wind the touch lead 220. As long as the arrangement of the virtual electrode block in the non-display area NA can be omitted, the first redundant winding segment 221 on the touch lead 220 can be arranged in the blank area between the cutting trajectory 400 and the display area AA.

[0046] In some alternative embodiments, please continue to refer to Figure 1 and Figure 2The display area AA includes a first edge 11 extending along a first direction X, a second edge 12 extending along a second direction Y, and an irregular edge 13 connecting the first edge 11 and the second edge 12. At least a portion of the first redundant winding segment 221 is located between the irregular edge 13 and the cutting trajectory 400. The irregular edge 13 has an irregular shape, while the touch lead 220 usually extends from the touch electrode 210 block to the circuit board 300 along a regular path. This makes it easy for a blank area to be formed between the irregular edge 13 and the cutting trajectory 400. The first redundant winding segment 221 being located in this area can better improve the uniformity of the wiring.

[0047] In some alternative embodiments, please continue to refer to Figure 1 and Figure 2 Multiple touch electrodes 210 are arranged in rows and columns along the first direction X and the second direction Y. The circuit board 300 is located on one side of the multiple touch electrodes 210 in the second direction Y. At least a portion of the first redundant winding segment 221 is located between the irregular edge 13 and the cutting trajectory 400 on the side of the display area AA facing away from the circuit board 300 in the second direction Y.

[0048] In these alternative embodiments, as described above, the touch leads 220 located on both sides of the display area AA in the first direction X and the second direction Y extend directly toward the circuit board 300. This causes a blank area to easily form between the irregular edge 13 and the cutting trajectory 400 on the side of the display area AA facing away from the circuit board 300 in the second direction Y. The first redundant winding segment 221 located in this area can better improve the uniformity of the wiring.

[0049] Optionally, the irregular edge 13 includes a first irregular edge located on the display area AA in the second direction Y away from the circuit board 300. The two first irregular edges are located on both sides of the display area AA in the first direction X. A first redundant winding segment 221 is provided between the two first irregular edges and the cutting trajectory 400 to better improve the uniformity of the wiring.

[0050] The number of touch electrodes 210 can vary. For a better illustration of the structure of this embodiment, please refer to [link / reference needed]. Figure 3 , Figure 3 This is a schematic diagram of the structure of a display panel 10 provided in another embodiment of the first aspect of this application. Figure 3 The example described uses nine touch electrodes 210 arranged in 3 rows and 3 columns, and touch leads 220 connecting the nine touch electrodes 210 and the circuit board 300. In other embodiments, the touch electrodes 210 may be arranged in other numbers in rows and columns.

[0051] In some alternative embodiments, such as Figure 3As shown, the touch component 200 also includes a terminal 230 connected to the touch electrode 210, and a touch lead 220 connected between the terminal 230 and the circuit board 300. M sets of terminals 230 are located on the same side of the display area AA. The touch lead 220 forms at least M-1 turns of wiring on the side of the M sets of terminals 230 away from the display area AA, ensuring the uniformity of the wiring. Figure 3 As shown, the display area AA has three sets of terminals 230 on the same side of the first direction X, and the touch lead 220 forms two loops of wiring on the side of the three sets of terminals 230 away from the display area AA.

[0052] The terminal 230 can be positioned in various ways; it can be located in the display area AA or at the edge of the display area AA. In some alternative embodiments, the terminal 230 can also extend from the touch electrode 210 to the non-display area NA, with the touch lead 220 connecting to the terminal 230 in the non-display area NA.

[0053] Optional, such as Figure 3 As shown, the terminal block 230 includes a first terminal block 231 located on at least one side of the display area AA in the first direction X and a second terminal block 232 located on at least one side of the display area AA in the second direction Y. The touch electrode block 210 includes a first electrode block arranged sequentially along the first direction X and a second electrode block arranged sequentially along the second direction Y.

[0054] When the first electrode block has a wire exiting from one side, the first terminal 231 is located on one side of the display area AA in the first direction X. When the first electrode block has a wire exiting from both sides, the two sets of first terminals 231 are located on both sides of the display area AA in the first direction X. When the second electrode block has a wire exiting from one side, the second terminal 232 is located on one side of the display area AA in the second direction Y. When the second electrode block has a wire exiting from both sides, the two sets of second terminals 232 are located on both sides of the display area AA in the second direction Y.

[0055] Figure 3 The example uses a rectangular display area AA. Please refer to [link / reference]. Figure 4 , Figure 4 This is a schematic diagram of the structure of a display panel 10 provided in another embodiment of the first aspect of this application. Figure 4 and Figure 3 The difference is that the display area AA is circular in shape. Figure 4 The layout pattern of the middle touch component 200 and Figure 3 Same. That is. Figure 4 The arrangement of the touch lead 220 and the touch electrode block 210 is the same as Figure 3 The same, the difference is Figure 4 A portion of the touch lead 220 is an arc that surrounds the circular display area AA.

[0056] Please see Figure 5 , Figure 5 This is a schematic diagram of the structure of a display panel 10 provided in another embodiment of the first aspect of this application. Figure 5 and Figure 3 The difference lies in the different ways the first electrode block and the second electrode block are led out, so the first terminal 231 and the second terminal 232 are positioned differently.

[0057] Optionally, when the touch lead 220 is Figure 5 In the structural form shown, the shape of the display area AA can also be circular.

[0058] In some alternative embodiments, such as Figure 5 As shown, at least two sets of terminals 230 are spaced apart on the same side of the display area AA. The touch lead 220 also includes a second redundant winding segment 223, at least a portion of which is located between the two sets of terminals 230 spaced apart.

[0059] Please continue reading. Figure 5 When multiple touch electrodes 210 are routed on both sides of the display area AA in the first direction X, that is, when multiple terminals 230 are distributed on both sides of the display area AA in the first direction X, it may cause a gap between two adjacent terminals 230 on the same side of the display area AA in the first direction X. This gap can lead to uneven wiring in the non-display area NA. At least a portion of the second redundant winding segment 223 is located between the two sets of terminals 230 with this gap distribution, which can further improve the unevenness of the wiring. Figure 5 As shown, the two sets of first terminals 231 are spaced apart on the same side of the display area AA, and at least part of the second redundant winding segment 223 is located between the two sets of first terminals 231 spaced apart.

[0060] In some alternative embodiments, please continue to refer to Figure 5 In the two sets of terminals 230 distributed at intervals, the touch lead 220 connected to the terminal 230 near the circuit board 300 extends toward the terminal 230 away from the circuit board 300 to form a second redundant winding segment 223.

[0061] Before the second redundant winding segment 223 is provided, in the two sets of spaced terminals 230, the wiring length of the touch lead 220 connected to the terminal 230 closer to the circuit board 300 is less than the wiring length of the touch lead 220 connected to the other terminal 230. This results in signal transmission differences due to the inconsistent lengths of the touch leads 220 connected to the two sets of spaced terminals 230. In this embodiment, the second redundant winding segment 223 is provided on the touch lead 220 connected to the terminal 230 closer to the circuit board 300 in the two sets of spaced terminals 230, which can improve the wiring length difference and signal transmission differences, and improve the performance of the touch component 200.

[0062] Optionally, there may be a gap between two adjacent first terminals 231, or there may be a gap between adjacent second terminals 232.

[0063] For example, on one side of the display area AA in the first direction X, there are two first terminals 231 spaced apart along the second direction Y, such as... Figure 5 As shown, the distance between the lower first terminal 231 and the circuit board 300 is relatively short. Before the second redundant winding segment 223 is set, the wiring length of the touch lead 220 connected to the lower first terminal 231 is less than the wiring length of the touch lead 220 connected to the upper first terminal 231. Setting the second redundant winding segment 223 on the touch lead 220 connected to the lower first terminal 231 can improve the wiring length difference between different touch leads 220, thereby improving signal transmission differences and improving the performance of the touch component 200.

[0064] For further information, please refer to [link / reference]. Figure 5 When there is a gap between two adjacent first terminals 231, the touch lead 220 including the second redundant winding segment 223 can be connected above the lower first terminal 231 and extend upward to form the second redundant winding segment 223. That is, the touch lead 220 including the second redundant winding segment 223 is connected to the side of the first connection terminal away from the circuit board 300 and extends in the direction away from the circuit board 300 to form the second redundant winding segment 223. This can reduce the gap between the second redundant winding segment 223 and the display area AA and better improve the uneven wiring.

[0065] In some alternative embodiments, please continue to refer to Figures 3 to 5 The M-group terminal block 230 includes a first distal end 230a that is away from the circuit board 300, and a plurality of touch leads 220 include a first distal end trace 220a connected to the first distal end 230a. At least a portion of the first distal end trace 220a includes a first redundant winding segment 221.

[0066] In these alternative embodiments, placing the first redundant winding segment 221 on the first far end trace 220a connecting the first far end 230a can avoid the touch lead 220 crossing caused by placing the first redundant winding segment 221 on other touch leads 220, which would affect the transmission of touch signals.

[0067] Optionally, the circuit board 300 is disposed on one side of the display area AA in the second direction Y. Optionally, the circuit board 300 may be located in the middle of the display area AA in the first direction X, or the circuit board 300 may be located on one side of the display area AA in the first direction X.

[0068] Optionally, the first remote terminal 230a can be either the first terminal 231 or the second terminal 232.

[0069] like Figure 3 and Figure 4 As shown, the first distal end 230a can be located on the side of the display area AA facing away from the circuit board 300 in the second direction Y. In this case, the first distal end 230a is one of the multiple second terminals 232 located on the side of the display area AA facing away from the circuit board 300 in the second direction Y, and the first distal end 230a is one of the multiple second connection terminals arranged along the first direction X that is far away from the circuit board 300. When the first redundant winding segment 221 is set on the first distal trace 220a connecting the first distal end 230a, it can avoid the first redundant winding segment 221 from crossing the touch lead 220 connected to other second terminals 232, thus avoiding affecting the transmission of touch signals.

[0070] In these alternative embodiments, the first distal trace 220a is connected to the first distal end 230a on the side of the circuit board 300 in the first direction X and extends in the direction away from the circuit board 300 to form a first redundant winding segment 221, and then continues to extend in the direction close to the circuit board 300.

[0071] like Figure 3 and Figure 5 As shown, the first distal end 230a can be located on at least one side of the display area AA in the first direction X. In this case, the first distal end 230a is one of the multiple first terminals 231 located on the same side of the display area AA in the first direction X, and the first distal end 230a is one of the multiple first connection terminals arranged along the second direction Y that is far from the circuit board 300. When the first redundant winding segment 221 is set on the first distal trace 220a connecting the first distal end 230a, it can avoid the first redundant winding segment 221 from crossing with the touch lead 220 connected to other first terminals 231, thus avoiding affecting the transmission of touch signals.

[0072] In these alternative embodiments, the first distal trace 220a is connected to the first distal end 230a on the side of the circuit board 300 in the second direction Y and extends in the direction away from the circuit board 300 to form a first redundant winding segment 221, and then continues to extend in the direction close to the circuit board 300.

[0073] In some alternative embodiments, please continue to refer to Figure 5 The touch electrode 210 does not have a terminal 230 on the side of the circuit board 300 in the second direction Y. At least part of the first redundant winding segment 221 is located on the side of the touch electrode 210 in the second direction Y away from the circuit board 300, so that the first redundant winding segment 221 can fill the blank area of ​​the display area AA in the second direction Y away from the chainsaw plate.

[0074] Optional, please continue reading Figure 5 When multiple first terminals 231 are respectively located on both sides of the display area AA in the first direction X, both the touch leads 220 connected to the terminals 230 on both sides in the first direction X include a first redundant winding segment 221, and the first redundant winding segment 221 is located on the side of the touch electrode 210 facing away from the circuit board 300 in the second direction Y. The first redundant winding segments 221 of the two can extend to the middle of the display area AA in the first direction X, or the first redundant winding segments 221 of the two can be stacked along the second direction Y.

[0075] Alternatively, please see Figure 6 , Figure 6 This is a schematic diagram of the structure of a display panel 10 provided in another embodiment of the first aspect of this application. Optionally, when the touch lead 220 is... Figure 6 In the structural form shown, the shape of the display area AA can also be circular.

[0076] like Figure 6 As shown, when multiple first terminals 231 are respectively located on both sides of the display area AA in the first direction X, one of the touch leads 220 connected to the terminals 230 on both sides in the first direction X includes a first redundant winding segment 221 and the first redundant winding segment 221 is located on the side of the touch electrode 210 in the second direction Y away from the circuit board 300.

[0077] In some alternative embodiments, such as Figures 3 to 6 As shown, at least a portion of the first redundant winding segment 221 is located in the same loop of wiring as at least one touch lead 220 connected to other terminals 230, in order to ensure the uniformity of wiring in the non-display area NA.

[0078] In some alternative embodiments, such as Figures 3 to 6As shown, at least a portion of the first distal trace 220a is located on the side of the other touch leads 220 that is away from the display area AA. This prevents the first distal trace 220a from crossing with other touch leads 220, thus avoiding interference with the transmission of touch signals.

[0079] Please refer to the following: Figures 3 to 7 , Figure 7 This is a schematic diagram of the structure of a display panel 10 provided in another embodiment of the first aspect of this application. Optionally, when the touch lead 220 is... Figure 7 In the structural form shown, the shape of the display area AA can also be circular.

[0080] In some alternative embodiments, such as Figures 3 to 7 As shown, the plurality of terminals 230 include intermediate terminals 230c located in the same row or column among the plurality of terminals 230. The plurality of touch leads 220 include intermediate traces 220c connected to the intermediate terminals 230c. When there is no gap between two adjacent intermediate terminals 230c, or when other terminals 230 are adjacent to the intermediate terminals 230c and there is no gap, the intermediate traces 220c are connected to the side of the intermediate terminals 230c away from the circuit board 300 and extend toward the circuit board 300.

[0081] The intermediate terminal 230c can be either the first terminal 231 or the second terminal 232. For example... Figure 3 As shown, when the first electrode block has a single-sided wire, multiple first terminals 231 are distributed sequentially on the same side of the display area AA. The middle terminal 230c among the multiple first terminals 231 is located between the other first terminals 231. The middle trace 220c is connected to the side of the middle terminal 230c away from the circuit board 300 and extends towards the circuit board 300.

[0082] In some alternative embodiments, such as Figures 3 to 7 As shown, the plurality of terminals 230 include a first proximal end 230b, and the touch lead 220 includes a first proximal end trace 220b. The first proximal end trace 220b can be connected to the side of the first proximal end 230b that is away from other terminals 230 in the same row or column.

[0083] For example, such as Figure 3 and Figure 4As shown, the plurality of terminals 230 include a first proximal end 230b located near the circuit board 300 in the first terminal 231 in the same column, with the second direction Y being the column direction. The plurality of touch leads 220 include a first proximal end trace 220b connected to the first proximal end 230b. The first proximal end trace 220b can be connected to the first proximal end 230b from the side of the first proximal end 230b away from the other terminals 230 in the same column, so that the first proximal end trace 220b and the first proximal end 230b are arranged along the second direction Y in the non-display area NA, which can reduce one loop of leads, thereby reducing the area of ​​the non-display area NA and reducing the bezel size of the display panel 10.

[0084] Or, such as Figure 3 and Figure 4 As shown, the plurality of terminals 230 include a first proximal end 230b located in the second terminal 232 in the same row near the circuit board 300, with the first direction X being the row direction. The plurality of touch leads 220 include a first proximal end trace 220b connected to the first proximal end 230b. The first proximal end trace 220b can be connected to the first proximal end 230b from the side of the first proximal end 230b away from the other terminals 230 in the same row, so that the first proximal end trace 220b and the first proximal end 230b are arranged along the first direction X in the non-display area NA, which can reduce one loop of leads, thereby reducing the area of ​​the non-display area NA and reducing the bezel size of the display panel 10.

[0085] Optional, please refer to Figure 8 , Figure 8 This is a schematic diagram of the structure of a display panel 10 provided in another embodiment of the first aspect of this application. Optionally, when the touch lead 220 is... Figure 8 In the structural form shown, the shape of the display area AA can also be circular. For example... Figure 8 As shown, both the first electrode block and the second electrode block have double-sided leads. Two sets of first terminals 231 are located on both sides of the first direction X, and two sets of second terminals 232 are located on both sides of the second direction Y. Each set of first terminals 231 includes a first distal end 230a, a first proximal end 230b, and an intermediate terminal 230c. Each set of multiple second terminals 232 includes a first distal end 230a, a first proximal end 230b, and an intermediate terminal 230c.

[0086] In some optional embodiments, multiple touch leads 220 form a multi-layer wiring in the winding area, with the distance between adjacent wiring layers ranging from 3 micrometers to 30 micrometers. This avoids the touch leads 220 being too close together, which could affect the transmission of touch signals, and also avoids the non-display area NA being too large due to excessive distance between adjacent wiring layers.

[0087] In some alternative embodiments, the line widths of the multiple touch leads 220 are equal. For example, the line width of a single touch lead 220 is consistent, that is, the line width of a single touch lead 220 is consistent at different positions, and the line widths of the multiple touch leads 220 are the same.

[0088] Please see Figure 9 , Figure 9 This is a schematic diagram of the structure of a display panel 10 provided in another embodiment of the first aspect of this application. Optionally, when the touch lead 220 is... Figure 9 In the structural form shown, the shape of the display area AA can also be circular.

[0089] In some alternative embodiments, such as Figure 9 As shown, the display panel 10 also includes a floating trace 600, which is suspended and not connected to other leads. Touch leads 220 are arranged around the floating trace 600. Touch leads 220 are arranged around the periphery of the floating trace 600. When static electricity accumulates on the floating trace 600 and is released, the static electricity can be conducted to the touch leads 220 without affecting the touch electrodes 210.

[0090] Optionally, touch leads 220 are provided on both sides of the floating trace 600 in the first direction X and on both sides of the virtual floating trace in the second direction Y. The touch leads 220 located around the floating trace 600 can be the same touch lead 220 or can be different touch leads 220.

[0091] In some alternative embodiments, please continue to refer to Figure 5 and Figure 9 The display panel 10 also includes a fill trace 700, one end of which is connected to the touch electrode 210, and the other end is a free end. The fill trace 700 is arranged adjacent to the display area AA. On the one hand, the fill trace 700 can improve uneven wiring; on the other hand, the fact that one end of the fill trace 700 is connected to the touch electrode 210, for example, through a terminal 230, can prevent the accumulation of static electricity on the fill trace 700.

[0092] Furthermore, in any of the above embodiments, when the length difference between multiple touch leads 220 is too large due to setting a first redundant winding segment 221 or a second redundant winding segment 223 on the touch lead 220, affecting the transmission of touch signals, a floating trace 600 and / or a filling trace 700 can be set to reduce the length of some touch leads 220 and improve the transmission of touch signals.

[0093] Please see Figure 10The second aspect of this application also provides a display device including the display panel of any of the first aspect embodiments described above. Since the display device provided in the second aspect of this application includes the display panel of any of the first aspect embodiments described above, it has the beneficial effects of the display panel of any of the first aspect embodiments described above, which will not be elaborated further here.
