[0053] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0054] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0055] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0056] In the description of this application, it should be noted that the terms "upper," "lower," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0057] It should be noted that, where there is no conflict, different features in the embodiments of this application can be combined with each other.

[0058] Please refer to Figure 1 , Figure 1 The wiring structure provided in this embodiment includes a wiring body 110 and a compensation structure 120.

[0059] The trace body 110 is the main body of a metal trace primarily used for transmitting electrical energy or signals, and the trace body 110 extends along a first direction. It should be noted that, in this embodiment, the first direction is the direction in which the trace body 110 extends, and different trace bodies 110 may have different first directions due to their different placement positions.

[0060] The compensation structure 120 includes a first contact portion 121, an extension portion 123, a connecting portion 122, and a second contact portion 124. The extension portion 123 extends parallel to the trace body 110 and is spaced apart from the trace body 110. The extension portion 123 is connected to the trace body 110 via the connecting portion 122. The first contact portion 121 protrudes from the trace body 110 toward the extension portion 123 but does not contact the extension portion 123. The second contact portion 124 protrudes from the extension portion 123 toward the trace body 110 but does not contact the trace body 110. In the first direction, the orthographic projection of the first contact portion 121 on the trace body 110 lies between the orthographic projections of the second contact portion 124 and the connecting portion 122 on the trace body 110.

[0061] For example, please refer to again Figure 1 The first contact portion 121 can extend from the trace body 110 in a second direction perpendicular to the first direction. The connecting portion 122 can extend from the trace body 110 in a second direction perpendicular to the first direction, and its extension length can be greater than the extension length of the first contact portion 121. The extension portion 123 can extend from one end of the connecting portion 122 away from the trace body 110 along the first direction and beyond the first contact portion 121, so that the first contact portion 121 is located between the trace body 110 and the extension portion 123, and the first contact portion 121 does not contact the extension portion 123. The second contact portion 124 can extend from one end of the extension portion 123 away from the connecting portion 122 toward the trace body 110, that is, in the opposite direction of the second direction, and its extension length is less than the extension length of the connecting portion 122, that is, the second contact portion 124 will not extend to contact the trace body 110.

[0062] Based on the above design, please refer to Figure 2When the trace body 110 is stretched in its first extension direction, the resistance of the trace body 110 increases. During this process, since the extension portion 123 is only connected to the trace body 110 via the connecting portion 122, the extension portion 123 is not stretched along with the trace body 110. Simultaneously, during the stretching process, the trace body 110 elongates as a whole, increasing the distance between the connecting portion 122 and the first contact portion 121. This causes the first contact portion 121 and the second contact portion 124 to gradually approach each other until they contact. At this point, the entire compensation structure 120 is essentially connected in parallel with the trace body 110, thereby reducing the overall resistance of the trace structure, offsetting the increased resistance of the trace body 110 due to elongation, and ensuring the stability of power supply or signal transmission in the trace structure.

[0063] Furthermore, given that the trace body 110 possesses a certain degree of elasticity, after the tension on the trace body 110 is released, it can shorten and recover, resulting in a decrease in its resistance value. In this case, the distance between the connecting portion 122 and the first contact portion 121 can decrease as the trace body 110 shortens and recovers, thereby separating the first contact portion 121 from the second contact portion 124, breaking the conductive path of the compensation structure 120, and restoring it to its original position. Figure 1 The structure shown is such that the overall resistance of the wiring structure is not too low.

[0064] For some possible implementations, please refer to Figure 3 The compensation structure 120 includes at least two contact groups (such as...) Figure 3 (As shown in the dashed box), each contact group includes a corresponding first contact 121 and a second contact 124. Within the same contact group, the orthographic projection of the first contact 121 onto the trace body 110 lies between the orthographic projections of the second contact 124 and the connecting portion 122 onto the trace body 110. At least two contact groups are arranged sequentially along the first direction. For example, the first contact 121 and the second contact 124 in multiple contact groups are alternately spaced along the first direction. In the first direction, each second contact 124 is located on the side of a first contact 121 away from the connecting portion 122. This improves the contact effectiveness between the first contact 121 and the second contact 124, preventing poor contact between a particular first contact 121 and second contact 124 from affecting the compensation effect of the compensation structure 120.

[0065] For some possible implementations, please refer to Figure 4The routing structure may further include at least two compensation structures 120. Each compensation structure 120 includes a corresponding first contact portion 121 and a second contact portion 124. The orthographic projection of the first contact portion 121 in the same compensation structure 120 onto the routing body 110 lies between the orthographic projections of the second contact portion 124 and the connecting portion 122 onto the routing body 110. At least two compensation structures 120 are arranged along the first direction. This improves the effectiveness of the compensation structure 120 in achieving its compensation function and avoids poor contact in one compensation structure 120 affecting the compensation effect.

[0066] Furthermore, in some possible implementations, please refer to... Figure 5 In any of the compensation structures, there is a first distance W between the first contact portion 121 and the second contact portion 124, and the first distance W is different in at least two of the compensation structures 120.

[0067] Therefore, please refer to Figure 6 When the trace body 110 is stretched to a certain extent, the compensation structure 120 with the smaller first spacing W is turned on first, offsetting part of the increased resistance of the trace body 110. At this time, the compensation structure 120 with the larger first spacing W is not yet turned on.

[0068] Please refer to the following: Figure 7 As the trace body 110 continues to be stretched, its resistance continues to increase until the compensation structure 120 with a larger first spacing W is turned on, thereby offsetting the continued increase in resistance of the trace body 110.

[0069] In this way, the multiple compensation units can be turned on in stages when the trace body 110 is stretched to different lengths, thereby compensating for and offsetting the increased resistance of the trace body 110 more smoothly and improving the uniformity of the overall resistance of the trace structure when stretched to different lengths.

[0070] For some possible implementations, please refer to Figure 8 The first contact portion 121 includes a first inclined surface that slopes toward the second contact portion 124, and the second contact portion 124 includes a second inclined surface that slopes toward the first contact portion 121. Preferably, the first inclined surface and the second inclined surface have the same slope. In this way, the contact area between the first contact portion 121 and the second contact portion 124 can be increased, thereby improving the contact effectiveness of the first contact portion 121 and the second contact portion 124.

[0071] For some possible implementations, please refer to Figure 9The wiring structure further includes an insulating layer 130. The insulating layer 130 covers the wiring body 110, and the insulating layer 130 includes an opening exposing the extension 123. The thickness of the insulating layer 130 is greater than the distance from the side of the extension 123 away from the wiring body 110 to the wiring body 110.

[0072] Preferably, the wiring structure further includes a protective layer 140. The protective layer 140 is located on the side of the insulating layer 130 away from the wiring body 110 and covers the opening. In this way, the insulating layer 130 and the protective layer 140 can form a protective space to accommodate the compensation structure 120, thereby preventing other components from pressing on the extension 123, causing the extension 123 to contact the first contact portion 121 or the second contact portion 124 to contact the wiring body 110.

[0073] Please refer to Figure 10 This embodiment also provides a method for manufacturing a wiring structure. The method for manufacturing a wiring structure can be used to manufacture the wiring structure provided in this embodiment. The steps of the method for manufacturing a wiring structure are described in detail below.

[0074] In step S110, a first metal layer is formed on a carrier layer 100, and the first metal layer is etched to form a trace body 110 extending along a first direction and a first contact portion 121. The first contact portion 121 protrudes from the trace body 110 toward a direction away from the carrier layer 100.

[0075] In this embodiment, the wiring structure can be formed on a carrier layer 100. In one possible implementation, the wiring structure can be formed in a thin film transistor (TFT) array substrate, and the carrier layer 100 can be a substrate layer, buffer layer, insulating layer 130, or planarization layer of the TFT array substrate.

[0076] Please refer to Figure 11 In this embodiment, after the first metal layer is formed on the carrier layer 100, the first metal layer can be etched to form the trace body 110 and the first contact portion 121.

[0077] In step S120, a sacrificial layer 210 is formed on the side of the wiring body 110 away from the bearing layer 100, and a groove is formed on the sacrificial layer 210.

[0078] Please refer to Figure 12The sacrificial layer 210 covers the first contact portion 121 and the surrounding trace body 110 along the first direction. Along the first direction, the sacrificial layer 210 includes a first end 211 and a second end 212, and in the first direction, the trench is located relative to the trace body 110 near the second end 212. The depth of the trench is less than the thickness of the sacrificial layer 210. For example, a sacrificial layer 210 that integrally covers the trace body 110 and the first contact portion 121 can be formed first, such as... Figure 13 As shown, the sacrificial layer 210 is then etched, retaining a portion of the sacrificial layer 210 and forming the trench, as shown. Figure 12 As shown.

[0079] In step S130, a second metal layer is formed on the side of the sacrificial layer 210 away from the trace body 110, such that the second metal layer forms an extension 123 covering the sacrificial layer 210, a second contact portion 124 filling the trench, and a connection portion 122 extending from the first end 211 and the second end 212 of the sacrificial layer 210 to make electrical contact with the trace body 110.

[0080] Please refer to Figure 14 In this embodiment, the second metal layer can be formed on the sacrificial layer 210 using the same material as the first metal layer. The second metal layer filling the trench can form the second contact portion 124, the second metal layer covering the sacrificial layer 210 can form the extension portion 123, and the second metal layer extending from the first end 211 and the second end 212 of the sacrificial layer 210 to the trace body 110 can form the connection portion 122.

[0081] Step S140: Remove the connecting portion 122 on one side of the second end 212 of the sacrificial layer 210.

[0082] In this embodiment, the second metal layer can be etched to remove at least the second metal layer on the side of the second end 212 of the sacrificial layer 210, so that the extension 123 does not contact the trace body 110, leaving only the second metal layer on the side of the first end 211 of the sacrificial layer 210. Simultaneously, the second metal layer covering the first metal layer can also be removed to form a shape such as... Figure 15 The structure shown.

[0083] Step S150: Remove the sacrificial layer 210.

[0084] In this embodiment, after step S140, the sacrificial layer 210 can be removed to obtain the desired result. Figure 1 The structure shown.

[0085] It should be noted that in this embodiment, the sacrificial layer 210 and the second metal layer need to be made of different materials, and the sacrificial layer 210 and the second metal layer need to react with different etching solutions. That is, the etching solution used to etch the metal of the sacrificial layer 210 will not react with the first metal layer and the second metal layer, and the etching solution used to etch the second metal layer will not react with the sacrificial layer 210. In one example, the material of the sacrificial layer 210 can be silver or silicon carbide, and the materials of the first metal layer and the second metal layer can be copper or aluminum.

[0086] In one possible implementation, the method for manufacturing the wiring structure may further include step S210 before step S150.

[0087] In step S210, an insulating layer 130 is formed on the side of the trace body 110 away from the carrier layer 100. The insulating layer 130 includes an opening that exposes the extension 123. The thickness of the insulating layer 130 is greater than the distance from the side of the extension 123 away from the trace body 110 to the trace body 110.

[0088] In this embodiment, please refer to Figure 16 The insulating layer 130 can be formed by using a mask and vapor deposition. The insulating layer 130 can cover part of the trace body 110 but expose the compensation structure 120.

[0089] After step S210, step S150 can be executed to remove the sacrificial layer 210, obtaining the desired result. Figure 17 The structure shown.

[0090] After step S150, the method for manufacturing the wiring structure may further include step S220.

[0091] In step S220, a protective layer 140 is formed on the side of the insulating layer 130 away from the trace body 110, and the protective layer 140 covers the opening.

[0092] Please refer to Figure 18 After removing the sacrificial layer 210, a protective layer 140 can be formed on the side of the insulating layer 130 away from the trace body 110, thereby preventing other components from pressing on the extension 123, causing the extension 123 to contact the first contact portion 121 or the second contact portion 124 to contact the trace body 110.

[0093] Based on the same inventive concept, this embodiment also provides a display panel, which includes a pixel island 20 and the wiring structure 10 provided in this embodiment. Please refer to... Figure 19 The pixel island 20 may include one or more sub-pixels 21, and adjacent pixel islands 20 are connected by at least one of the wiring structures 10. Thus, when adjacent pixel islands 20 are stretched and the spacing increases, the compensation structure 120 in the wiring structure 10 can offset the increased resistance of the wiring body 110.

[0094] This embodiment also provides an electronic device, which includes the display panel provided in this embodiment.

[0095] In summary, the wiring structure, the manufacturing method of the wiring structure, the display panel, and the electronic device provided in this application embodiment, by setting a compensation structure, can conduct when the wiring body is stretched to a certain extent, thereby connecting in parallel with the wiring body. In this way, the increased resistance of the wiring body due to stretching can be offset, thereby maintaining the overall resistance value of the entire wiring structure and ensuring the stability of power supply or signal transmission of the wiring structure.

[0096] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0097] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
