Description

Technical Field

[0001] The present application belongs to the field of display technology, and in particular, relates to a display panel and a display device. Background Art

[0002] In a display panel, the display panel includes a display area and a non-display area. The display area is provided with signal lines such as data signal lines and scanning signal lines to control the display of the picture, and the non-display area is provided with a driving circuit and a fan-out lead, and the fan-out lead is used to transmit signals for the signal lines such as the data signal lines. A plurality of fan-out leads are usually arranged in a concentrated manner to form a fan-out area located in the non-display area.

[0003] In medium and large-sized display panels, multiple driver chips are required to connect fan-out lines, and each driver chip corresponds to a set of fan-out lines. Due to the size limitation of the flexible circuit board, these driver chips may not be evenly arranged relative to the display area, which leads to large length differences between the fan-out lines corresponding to different driver chips. As a result, the impedance of different fan-out lines is different, which in turn affects the signal transmission speed of the fan-out lines, resulting in display defects such as uneven display. Summary of the invention

[0004] Embodiments of the present application provide a display panel and a display device, aiming to improve the display effect of the display panel.

[0005] In a first aspect, an embodiment of the present application provides a display panel, the display panel includes a fan-out area, the fan-out area includes: a first group of fan-out lines, including a plurality of first fan-out lines arranged in parallel along a first direction; a second group of fan-out lines, adjacent to the first group of fan-out lines in the first direction, the second group of fan-out lines including compensation lines and a plurality of second fan-out lines arranged along the first direction, the second fan-out lines including N short fan-out lines adjacent to the first group of fan-out lines, N is a positive integer greater than 0, wherein a wiring spacing is formed between the short fan-out lines and the first fan-out lines, the length of at least some of the short fan-out lines is less than the length of the adjacent first fan-out lines, each of the N short fan-out lines is electrically connected to at least one compensation line, and the compensation line extends from the short fan-out line to the wiring spacing.

[0007] In the display panel provided in the embodiment of the present application, the fan-out area of ​​the display panel includes a first group of fan-out lines and a second group of fan-out lines arranged in parallel along a first direction. The second group of fan-out lines includes a plurality of second fan-out lines arranged in parallel along the first direction, and the first group of fan-out lines includes a plurality of first fan-out lines arranged in parallel along the first direction, and the length of at least some of the short fan-out lines is less than the length of the adjacent first fan-out lines, so the impedance of the short fan-out lines and the first fan-out lines is different. The short fan-out line is electrically connected to at least one compensation line, which can reduce the length difference between the short fan-out line and the first fan-out line, thereby changing the difference in signal transmission speed between the short fan-out line and the first fan-out line, improving the uneven display phenomenon of the display panel, and improving the display effect of the display panel. In addition, the compensation line is located within the wiring spacing formed between the short fan-out line and the first fan-out line, and there is no need to set a wiring area for the compensation line, which is conducive to the narrow frame design of the display panel.

For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0028] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0029] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0030] In the embodiments of the present application, the term “electrically connected” may refer to a direct electrical connection between two components, or may refer to an electrical connection between two components via one or more other components.

[0031] It is obvious to those skilled in the art that various modifications and changes can be made in the present application without departing from the spirit or scope of the present application. Therefore, the present application is intended to cover modifications and changes of the present application that fall within the scope of the corresponding claims (technical solutions for protection) and their equivalents. It should be noted that the implementation methods provided in the embodiments of the present application can be combined with each other without contradiction.

[0032] Before describing the technical solutions provided by the embodiments of the present application, in order to facilitate the understanding of the embodiments of the present application, the present application first specifically describes the problems existing in the prior art:

[0033] As mentioned above, the inventor of the present application discovered that the related art has the problem of uneven display of the display panel.

[0034] In order to solve the problem of abnormal conditions such as dark lines or bright lines appearing at fixed positions of the display panel, the inventor of the present application first studied and analyzed the root causes of the above technical problems. The specific research and analysis process is as follows:

[0035] The inventor of this application discovered that Figure 1As shown, the display panel includes a display area AA' and a non-display area NA', wherein the non-display area NA' includes a fan-out area SS' located on one side of the display area AA' in the second direction Y, and the fan-out area SS' includes a plurality of driver chips and a plurality of groups of fan-out lines arranged in parallel along a first direction X, and each driver chip transmits a driving signal to a data signal line and a scanning signal line in the display area of ​​the display panel through each group of fan-out lines. Each group of fan-out lines includes a plurality of fan-out lines arranged in parallel along the first direction X.

[0036] In order to facilitate the connection between multiple driver chips and the flexible circuit board, multiple driver chips are arranged close to the flexible circuit board, which results in asymmetric positions between the driver chips and their corresponding set of fan-out lines, and the driver chips cannot be centered in the middle of their corresponding set of fan-out lines in the first direction.

[0037] For example, Figure 1 As shown, the fan-out area SS' includes a first group of fan-out lines 100' and a second group of fan-out lines 200' adjacently arranged along a first direction, the first group of fan-out lines 100' includes first fan-out lines 110' arranged in parallel along the first direction X, and the second group of fan-out lines 200' includes second fan-out lines 210' arranged in parallel along the first direction X. The first group of fan-out lines 100' is connected to a first driver chip 400', and the second group of fan-out lines 200' is connected to a second driver chip 500'. Due to the size limitation of the flexible circuit board connected to the first driver chip 400' and the second driver chip 500', the first driver chip 400' and the second driver chip 500' cannot be evenly arranged relative to the display area AA, which results in that the second fan-out lines 210' in the second group of fan-out lines 200', which are close to the first group of fan-out lines 100', are shorter, while the first fan-out lines 110' in the first group of fan-out lines 100', which are close to the second group of fan-out lines 200', are longer, that is, the adjacent second fan-out lines 210' are shorter than the first fan-out lines 110', and the length difference is large, resulting in a sudden change in the length of the fan-out lines.

[0038] After the signal is transmitted via the shorter second fan-out line 210' in the second group of fan-out lines 200', the signal continues to be transmitted via the first fan-out line 110'. The signal will be transmitted via two fan-out lines with greatly different lengths, resulting in display differences due to signal transmission differences, affecting the display effect of the display panel.

[0039] In order to solve the above technical problems, this application is proposed.

[0040] Please also read Figure 2 and Figure 3 , Figure 2 It is a structural schematic diagram of a display panel provided in an embodiment of the present application. Figure 3 yes Figure 2 Schematic diagram of the local enlarged structure in.

[0041] like Figure 2 and Figure 3 As shown, the display panel provided in the embodiment of the present application includes a fan-out area SS, and the fan-out area SS includes: a first group of fan-out lines 100, including a plurality of first fan-out lines 110 arranged in parallel along a first direction X; a second group of fan-out lines 200, which are adjacent to the first group of fan-out lines 100 in the first direction X, the second group of fan-out lines 200 including compensation lines 300 and a plurality of second fan-out lines 201 arranged along the first direction X, the second fan-out lines 201 including N short fan-out lines 210 adjacent to the first group of fan-out lines 100, N being a positive integer greater than 0, wherein a wiring spacing BS is formed between the short fan-out lines 210 and the first fan-out lines 110, the length of at least some of the short fan-out lines 210 being less than the length of the adjacent first fan-out lines 110, each of the N short fan-out lines 210 being electrically connected to at least one compensation line 300, and the compensation line 300 extending from the short fan-out line 210 to the wiring spacing BS.

[0042] In the display panel provided in the embodiment of the present application, the fan-out area SS of the display panel includes a first group of fan-out lines 100 and a second group of fan-out lines 200 arranged in parallel along a first direction X. The second group of fan-out lines 201 arranged in parallel along the first direction X in the second group of fan-out lines 200 include short fan-out lines 210, and the first group of fan-out lines 100 includes a plurality of first fan-out lines 110 arranged in parallel along the first direction X. The length of at least some of the short fan-out lines 210 is less than the length of the adjacent first fan-out lines 110, so the impedance of the short fan-out lines 210 and the first fan-out lines 110 is different. The short fan-out lines 210 are electrically connected to at least one compensation line 300, which can reduce the length difference between the short fan-out lines 210 and the first fan-out lines 110, thereby changing the difference in signal transmission speed between the short fan-out lines 210 and the first fan-out lines 110, improving the display unevenness of the display panel, and improving the display effect of the display panel. In addition, the compensation line 300 is located within the wiring spacing BS formed between the short fan-out line 210 and the first fan-out line 110 , and there is no need to set up an additional wiring area for the compensation line 300 , which is beneficial to the narrow frame design of the display panel.

[0043] like Figure 2 As shown, the embodiment of the present application is illustrated by taking N as 3. In other embodiments, N may also be an integer greater than 0, such as 1, 2, 4, etc. Figure 2 As shown, when the fan-out area SS is provided with multiple groups of fan-out lines arranged side by side along the first direction X, the embodiment of the present application takes the two groups of fan-out lines from the left as an example for illustration. In other embodiments, the first group of fan-out lines 100 and the second group of fan-out lines 200 can also be fan-out line groups at other positions within the multiple groups of fan-out lines.

[0044] Optionally, the plurality of first fan-out lines 110 in the first group of fan-out lines 100 include long fan-out lines 110a, which are arranged adjacent to the second group of fan-out lines 200. The number of long fan-out lines 110a may be an integer greater than 0. The length of the long fan-out line 110a is greater than that of the short fan-out line 210.

[0045] Optionally, the display panel further includes a first driver chip 400 and a second driver chip 500 , a plurality of first fan-out lines 110 in the first group of fan-out lines 100 are connected to the first driver chip 400 , and a plurality of second fan-out lines 201 in the second group of fan-out lines 200 are connected to the second driver chip 500 .

[0046] In the first group of fan-out lines 100, a plurality of first fan-out lines 110 are arranged in parallel along a first direction X, and at least a portion of the plurality of first fan-out lines 110 extends in a second direction Y perpendicular to the first direction X, or at least a portion of the plurality of first fan-out lines 110 may be arranged obliquely relative to the second direction Y, or at least a portion of the plurality of first fan-out lines 110 first extends perpendicularly from the driver chip along the second direction Y, and then extends in a direction oblique to the second direction Y, as long as the plurality of first fan-out lines 110 are arranged in parallel along the first direction X.

[0047] Similarly, in the second group of fan-out lines 200, a plurality of second fan-out lines 201 are arranged in parallel along the first direction X, and at least a portion of the plurality of second fan-out lines 201 can be extended and formed along the second direction Y, or at least a portion of the plurality of second fan-out lines 201 can be arranged obliquely relative to the second direction Y, or at least a portion of the plurality of second fan-out lines 201 first extend vertically from the driver chip along the second direction Y, and then extend in an oblique direction relative to the second direction Y, as long as the plurality of second fan-out lines 201 are arranged in parallel along the first direction X. Among them, some of the second fan-out lines 201 in the plurality of second fan-out lines 201 are short fan-out lines 210 whose length is less than the long fan-out lines 110a in the first fan-out lines 110.

[0048] Among the multiple second fan-out lines 201, the length of the portion of the second fan-out lines 201 close to the first group of fan-out lines 100 is shorter than the long fan-out line 110a in the first fan-out line 110. Therefore, the portion of the second fan-out lines 201 close to the first group of fan-out lines 100 among the multiple second fan-out lines 201 is a short fan-out line 210, and a wiring spacing BS is formed between the short fan-out line 210 and the first group of fan-out lines 100.

[0049] See also Figure 4 and Figure 5 , Figure 4 It is a schematic diagram of the enlarged structure of a second group of fan-out lines 200 of a display panel provided in an embodiment of the present application. Figure 5It is a schematic diagram of an enlarged structure of a second group of fan-out lines 200 of a display panel provided in another embodiment of the present application.

[0050] In some optional embodiments, such as Figure 4 and Figure 5 As shown, the short fan-out line 210 includes a first sub-segment 211 and a second sub-segment 212, the first sub-segments 211 of the N short fan-out lines 210 extend along the second direction Y, the second sub-segments 212 of the N short fan-out lines 210 are inclined relative to the second direction Y, the compensation line 300 is connected to the first sub-segment 211 and / or the second sub-segment 212, and the second direction Y intersects with the first direction X.

[0051] In these optional embodiments, the short fan-out line 210 includes a first sub-segment 211 extending along the second direction Y and a second sub-segment 212 arranged obliquely relative to the second direction Y. When the short fan-out line 210 is connected to the second driver chip 500, a plurality of first sub-segments 211 may be arranged side by side along the first direction X and connected to the second driver chip 500, thereby reducing the space occupied by the connection end of the short fan-out line 210 connected to the second driver chip 500, and facilitating the connection between the short fan-out line 210 and the second driver chip 500.

[0052] Optionally, the second sub-segment 212 is located on a side of the first sub-segment 211 away from the second driving chip 500 in the second direction Y, and the second sub-segment 212 is tilted toward the first group of fan-out lines 100 in a direction away from the first sub-segment 211 .

[0053] The shape of the compensation line 300 can be set in various ways. In some optional embodiments, for example Figures 2 to 5 As shown, the compensation line 300 includes at least one group of compensation segments 310, each group of compensation segments 310 includes two side portions 311 arranged opposite to each other along the second direction Y, and a bottom 312 connected between the two side portions 311, and at least one of the two side portions 311 is interconnected with the short fan-out line 210.

[0054] In these optional embodiments, the compensation section 310 of the compensation line 300 includes a side 311 and a bottom 312, and the compensation section 310 is connected to the short fan-out line 210 through at least one of the side sections 311, that is, the compensation section 310 located at the wiring spacing BS is roughly U-shaped, so that the length of the compensation section 310 is longer, which can improve the compensation ability of the compensation section 310 for the short fan-out line 210.

[0055] The side portion 311 may be connected to the first subsection 211 and / or the second subsection 212. Optionally, Figure 4As shown, the compensation line 300 is connected to the first subsection 211, and both side portions 311 of the compensation section 310 are connected to the first subsection 211. In these embodiments, the compensation line 300 is connected to the first subsection 211 extending along the first direction X, and the shape of the compensation line 300 can be set to be relatively regular, for example, the side portion 311 of the compensation line 300 can extend along the second direction Y, and the bottom 312 extends along the first direction X, which is convenient for the preparation of the compensation line 300.

[0056] In some other optional embodiments, Figure 5 As shown, the compensation line 300 can also be connected to the second sub-segment 212 , and the compensation line 300 includes an adjustment segment 320 extending along the first direction X, one of the two side portions 311 is directly connected to the second sub-segment 212 , and the other is connected to the second sub-segment 212 through the adjustment segment 320 .

[0057] In these optional embodiments, the compensation line 300 is connected to the second sub-segment 212, and since the second sub-segment 212 is arranged to be inclined relative to the second direction Y, when one of the side portions 311 of the compensation line 300 is connected to the second sub-segment 212 through the adjustment segment 320, the adjustment segment 320 compensates for the inclination of the second sub-segment 212, so that both side portions 311 of the compensation line 300 can extend along the first direction X, and the bottom 312 of the compensation line 300 can extend along the second direction Y. Thus, each part of the compensation segment 310 can be arranged along the first direction X and the second direction Y, and the shape of the compensation line 300 can be simplified.

[0058] In addition, by providing the adjustment section 320, it is possible to avoid the angle between the side portion 311 and the second sub-segment 212 being too small when the side portion 311 is directly connected to the second sub-segment 212, making it difficult to etch the compensation line 300, and the angle between the side portion 311 and the second sub-segment 212 being too small may also cause the side portion 311 and the second sub-segment 212 to adhere to each other, resulting in uneven routing width. Therefore, by providing the adjustment section 320, the preparation of the compensation line 300 can be simplified and the preparation accuracy of the compensation line 300 can be improved.

[0059] See also Figure 6 , Figure 6 It is a schematic diagram of an enlarged structure of a second group of fan-out lines 200 of a display panel provided in yet another embodiment of the present application.

[0060] Optional, such as Figure 6 As shown, the compensation line 300 may further include a plurality of compensation segments 310, wherein at least one group of compensation segments 310 is connected to the first sub-segment 211, and at least one group of compensation segments 310 is connected to the second sub-segment 212, so as to improve the compensation capability of the compensation line 300 for the length of the short fan-out line 210, and further reduce the length difference between the short fan-out line 210 and the first fan-out line 110.

[0061] See also Figures 4 to 7 , Figure 7 It is a schematic diagram of an enlarged structure of a second group of fan-out lines 200 of a display panel provided in yet another embodiment of the present application.

[0062] In some optional embodiments, such as Figures 4 to 7 As shown, in any of the above embodiments, the angle between the side portion 311 and the short fan-out line 210 is greater than 0 degrees and less than 180 degrees. By adjusting the angle between the side portion 311 and the short fan-out line 210, the side portion 311 can extend toward a direction with a larger wiring spacing BS, and then a longer compensation line 300 can be arranged to improve the compensation capability of the compensation line 300 for the length of the short fan-out line 210.

[0063] Optionally, the side portion 311 may be linear or arc-shaped. When the side portion 311 is arc-shaped, the angle between the side portion 311 and the short fan-out line 210 is the angle between the line connecting two opposite ends of the side portion 311 and the short fan-out line 210 .

[0064] When each of the N short fan-out lines 210 is connected to a compensation line 300, and N is an integer greater than 1, a plurality of compensation lines 300 are formed, and the plurality of compensation lines 300 include a plurality of groups of compensation segments 310. Figures 4 to 7 As shown, in the same group of compensation segments 310, the compensation segments 310 of multiple compensation lines 300 are nested with each other to reduce the space size occupied by the multiple compensation lines 300. When N is an integer greater than 2, the distance between the bottoms 312 of two adjacent compensation segments 310 is equal, so that the distribution of the multiple compensation segments 310 is more uniform.

[0065] In some optional implementations, the short fan-out lines 210 are located in the same metal layer, each of the N short fan-out lines 210 is electrically connected to a group of compensation segments 310 in a compensation line 300, and the compensation line 300 and the short fan-out lines 210 are located in the same metal layer. The short fan-out lines 210 and the compensation lines 300 can be simultaneously prepared in the same preparation process step, which can simplify the preparation of the display panel and improve the preparation efficiency of the display panel.

[0066] In some other optional embodiments, Figure 6 As shown, each of the N short fan-out lines 210 is electrically connected to at least two groups of compensation segments 310 in a compensation line 300. By providing multiple groups of compensation segments 310, on the one hand, the compensation capability of the compensation line 300 for the length of the short fan-out line 210 can be improved, and on the other hand, by reasonably setting the shapes of the multiple groups of compensation segments 310, the multiple groups of compensation segments 310 can be more evenly filled in the wiring spacing BS, thereby improving the uniformity of the wiring in the non-display area NA of the display panel.

Fig. 9 It is a schematic diagram of an enlarged structure of a second group of fan-out lines 200 of a display panel provided in yet another embodiment of the present application.

[0068] Optional, such as Figure 8 and Fig. 9 As shown, the fan-out area SS includes a first area SS1 and a second area SS2, the same short fan-out line 210 includes a first section 213 and a second section 214, the first section 213 is located in the first area SS1, the second section 214 is located in the second area SS2, at least one group of compensation sections 310 is located in the first area SS1 and connected to the first section 213, and / or at least one group of compensation sections 310 is located in the second area SS2 and connected to the second section 214. In these optional embodiments, by partitioning the fan-out area SS and the short fan-out line 210, the short fan-out line 210 can be prepared in sections.

[0069] In some optional embodiments, such as Figure 2 , Figure 8 and Fig. 9 As shown, the distance between the first section 213 and the first group of fan-out lines 100 is smaller than the distance between the second section 214 and the first group of fan-out lines 100, at least two groups of compensation sections 310 are both located in the second area SS2, and at least two groups of compensation sections 310 are connected between the first section 213 and the second section 214.

[0070] There are many ways to divide the fan-out area SS into the first area SS1 and the second area SS2. Figure 8 and Fig. 9 The dot-dash line extending along the first direction X illustrates the boundary between the first area SS1 and the second area SS2. In other embodiments, the boundary between the first area SS1 and the second area SS2 may also be located at other positions in the second direction Y of the fan-out area SS.

[0071] In these optional embodiments, the distance between the second section 214 in the second area SS2 and the first group of fan-out lines 100 is large, so the wiring spacing BS is large in the second area SS2. The compensation segments 310 are all arranged in the second area SS2, and there is a large space in the second area SS2 for wiring of multiple compensation segments 310 and multiple compensation lines in the compensation segments 310, which can prevent the compensation segments 310 from being short-circuited to each other and affecting the yield of the display panel.

[0072] Optional, such as Figure 8 and Fig. 9As shown, the compensation section 310 is located between the first section 213 and the second section 214. In the short fan-out line 210 and the compensation section 310 connected to each other, the compensation section 310 includes a first compensation section 310a connected to at least one first section 213, and a second compensation section 310b connected to at least one second section 214. The compensation section 310 is divided into two sections, namely the first compensation section 310a and the second compensation section 310b. The first compensation section 310a is connected to the first section 213, and the second compensation section 310b is connected to the second section 214, so that different parts of the compensation section 310 can be connected to different sections, and different sections are compensated respectively.

[0073] The first section 213 and the second section 214 may be located in the same film layer or in different film layers. Figure 8 and Fig. 9 A solid line indicates that the line segment is located in one of the film layers, and a dotted line indicates that the line segment is located in the other film layer.

[0074] Optional, such as Figure 8 As shown, when the first section 213 and the second section 214 are located in different film layers, the first compensation section 310a and the first section 213 are arranged in the same layer, and the second compensation section 310b and the second section 214 are arranged in the same layer.

[0075] On one hand, the first compensation segment 310a can be prepared simultaneously when the first segment 213 is prepared, and the second compensation segment 310b can be prepared simultaneously when the second segment 214 is prepared, which can simplify the preparation process of the display panel and improve the preparation efficiency of the display panel.

[0076] On the other hand, the first compensation segment 310a is connected to the first segment 213, and the second compensation segment 310b is connected to the second segment 214, so the first compensation segment 310a is located on the side of the second compensation segment 310b facing the first segment 213, and the second compensation segment 310b is located on the side of the first compensation segment 310a facing the second segment 214. That is, the first compensation segment 310a and the first segment 213 arranged on the same layer are connected to each other, and the second compensation segment 310b and the second segment 214 arranged on the same layer are connected to each other. The first compensation segment 310a and the second compensation segment 310b of different layers are connected through vias, and it is only necessary to change the line between the first compensation segment 310a and the second compensation segment 310b, which can reduce the number of line changes between different metal layers.

[0077] Optionally, the short fan-out line 210 between the first compensation segment 310 a and the second compensation segment 310 b may be located in the same film layer as the first compensation segment 310 a or the second compensation segment 310 b . Figure 8In the example, the short fan-out line 210 between the first compensation section 310a and the second compensation section 310b is located in the same film layer as the second compensation section 310b. In other embodiments, Figure 8 The short fan-out line 210 between the first compensation section 310a and the second compensation section 310b may also be located in the same film layer as the first compensation section 310a.

[0078] In some other optional embodiments, the first section 213 and the second section 214 are located in the same film layer. When the first section 213 and the second section 214 are located in the same film layer, one of the first compensation section 310a and the second compensation section 310b is located in the same film layer as the first section 213 and the second section 214, or the first compensation section 310a and the second compensation section 310b are not located in the same film layer as the first section 213 and the second section 214.

[0079] like Fig. 9 As shown, the first section 213 and the second section 214 are located in the same film layer, the first compensation section 310a and the second compensation section 310b are located in the same film layer, and the first compensation section 310a and the second compensation section 310b are not in the same film layer as the first section 213 and the second section 214. In these optional embodiments, the compensation line 300 is in the same film layer, and the short fan-out line 210 is in the same film layer, and the compensation line 300 and the short fan-out line 210 can be prepared separately in different preparation processes.

[0080] In some other optional embodiments, Fig.10 As shown, the first section 213 and the second section 214 are located in the same film layer, and one of the first compensation section 310a and the second compensation section 310b is located in the same film layer as the first section 213 and the second section 214. The embodiment of the present application is illustrated by taking the second compensation section 310b and the first section 213 and the second section 214 as examples in which the second compensation section 310b and the first section 213 and the second section 214 are located in different film layers, and the first compensation section 310a and the first section 213 and the second section are located in the same film layer. That is, in the embodiment of the present application, the first section 213, the first compensation section 310a and the second section 214 are located in the same film layer, the second compensation section 310b is located in another film layer, and the second compensation section 310b and the first compensation section 310a and the second section 214 are all required to be replaced.

[0081] Optionally, when the short fan-out line 210 includes a first sub-segment 211, a second sub-segment 212, a first section 213, and a second section 214, as Fig.10 As shown, the first section 213 and the first sub-section 211 located in the first area SS1 and tilted relative to the second direction Y can be the same part of the short fan-out line 210, and at least a part of the second section 214 and the second sub-section 212 extending along the second direction Y can be the same part of the short fan-out line 210. Optional, please continue to refer to Fig.10 The portion of the first sub-segment 211 that is tilted relative to the second direction Y and located in the second area SS2 and the portion of the second section 214 are the same portion of the short fan-out line 210 .

[0082] The first sub-segment 211 and the second sub-segment 212 are classified according to the extension direction of the short fan-out line 210, and the first section 213 and the second section 214 are classified according to the position of the short fan-out line 210. The portion of the short fan-out line 210 extending along the second direction Y can be considered as the first sub-segment 211, and the portion of the short fan-out line 210 inclined relative to the second direction Y can be considered as the second sub-segment 212. The portion of the short fan-out line 210 located in the first area SS1 is the first section 213, and the portion of the short fan-out line 210 located in the second area SS2 is the second section 214.

[0083] In some optional embodiments, such as Figures 8 to 10 As shown, the first compensation section 310a includes two first side portions 311a and a first bottom portion 312a connected between the two first side portions 311a; the second compensation section 310b includes two second side portions 311b and a second bottom portion 312b connected between the two second side portions 311b, wherein the length of the second side portion 311b connected to the same short fan-out line 210 is greater than the length of the first side portion 311a.

[0084] Before the compensation line 300 is set, the second section 214 is located in the second area SS2 and directly connected to the first section 213 of the first area SS1. When the compensation line 300 is set in the second area SS2, the compensation line 300 occupies the area originally used to set the second section 214. Since the first compensation section 310a and the second section 214 are set in different layers, the first compensation section 310a occupies the position of the wire that should be set in the same layer as the second section 214, resulting in a reduction in the length of the wire set in the same layer as the second section 214. In the embodiment provided in the present application, the length of the second side portion 311b is greater than the length of the first side portion 311a, so that the second side portion 311b can compensate for the length of the wire set in the same layer as the second section 214.

[0085] Optional, such as Fig. 9 and Fig.10 As shown, the length difference L1 between the second side portion 311b and the first side portion 311a connected to the same short fan-out line 210 is equal to the length L2 of the first bottom portion 312a. One of the second side portions 311b can be used to compensate for the imbalance caused by the extra first bottom portion 312a, and the other second side portion 311b can be used to compensate for the length of the wire that should be set at the same layer as the second section 214 at the location of the first bottom portion 312a, thereby balancing the wire lengths of each metal layer.

[0086] In some optional embodiments, the plurality of first bottoms 312a and the plurality of second bottoms 312b are spaced apart along the first direction X, and the spacing D1 between two adjacent first bottoms 312a is smaller than the distance D2 between two adjacent second bottoms 312b. When the spacing D1 between any two adjacent first bottoms 312a is equal, the distance D2 between any two adjacent second bottoms 312b is equal, and the spacing D1 between two adjacent first bottoms 312a is smaller than the distance D2 between two adjacent second bottoms 312b, the length of the second side portion 311b can be greater than the length of the first side portion 311a, and the second side portion 311b can be used to compensate for the length of the wire disposed on the same layer as the second section 214.

[0087] In some optional embodiments, such as Fig.11 As shown, the N short fan-out lines 210 include Q groups, each group includes one or multiple adjacent fan-out lines, Q is a positive integer; the first section 213 of the fan-out line in the group with an odd arrangement number in the Q groups is located at the first metal layer, and the second section 214 of the fan-out line in the group with an odd arrangement number in the Q groups is located at the second metal layer; the first section 213 of the fan-out line in the group with an even arrangement number in the Q groups is located at the second metal layer, and the second section 214 of the fan-out line in the group with an even arrangement number in the Q groups is located at the second metal layer. The second section 214 of the fan-out line is located in the first metal layer; or, the first section 213 of the fan-out line in the group with odd arrangement numbers among the Q groups is located in the second metal layer, and the second section 214 of the fan-out line in the group with odd arrangement numbers among the Q groups is located in the first metal layer; the first section 213 of the fan-out line in the group with even arrangement numbers among the Q groups is located in the first metal layer, and the second section 214 of the fan-out line in the group with even arrangement numbers among the Q groups is located in the second metal layer.

[0088] In these optional embodiments, the first sections 213 of two adjacent groups of fan-out lines are located in different metal layers, which can avoid short circuit connection caused by the first sections 213 of two adjacent groups of fan-out lines being too close. Fig.11 and Figures 8 to 10 The boundary position between the first area SS1 and the second area SS2 is different.

[0089] Optionally, one or more short fan-out lines 210 may be provided in the same group. Fig.11 Taking one short fan-out line 210 in the same group as an example, in other embodiments, the same group may have more than two short fan-out lines 210. Optionally, the number of short fan-out lines 210 in different groups is equal.

[0090] In some optional embodiments, the length variation trend of the compensation line 300 connected to the N short fan-out lines 210 is the same as the length variation trend of the N short fan-out lines 210 .

[0091] For example, in two adjacent end fan-out lines, when the length of one of the short fan-out lines 210 is smaller than the length of the other short fan-out line 210, the length of the compensation line 300 connected to one of the fan-out lines is smaller than the length of the compensation line 300 connected to the other short fan-out line 210, so that the impedance of the short fan-out line 210 after connecting the compensation line 300 has a smooth transition.

[0092] The embodiment of the second aspect of the present application also provides a display device, including the display panel of any of the above-mentioned embodiments of the first aspect. Since the display device provided by the embodiment of the second aspect of the present application includes the display panel of any of the above-mentioned embodiments of the first aspect, the display device provided by the embodiment of the second aspect of the present application has the beneficial effects of the display panel of any of the above-mentioned embodiments of the first aspect, which will not be repeated here.
