[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] In the following description, for the purpose of explanation rather than limitation, specific details such as specific system structures, interfaces, and technologies are provided to facilitate a thorough understanding of the present application.

[0031] The terms "first", "second", and "third" in this application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second", and "third" can explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. All directional indications in the embodiments of this application (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. The terms "including" and "having" in the embodiments of this application and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or components inherent to these processes, methods, products, or devices.

[0032] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0034] See also Figure 1 and Figure 2 , Figure 1 It is a schematic diagram of the local structure of the binding part in the prior art. Figure 2 yes Figure 1 A schematic diagram of the forces acting on the binding portion during the binding process.

[0035] The display panel generally includes a panel portion and a binding portion, and the binding portion is arranged on the side of the panel portion. The binding portion includes a plurality of binding pads 01 and a connecting wire 02. The plurality of binding pads 01 are generally arranged in a plurality of rows and columns. The connecting wire 02 is generally arranged between two adjacent rows of binding pads 01 and / or between two adjacent columns of binding pads 01. The connecting wire 02 is used to connect the binding pads 01 and the panel portion.

[0036] The outline of the binding pad 01 is usually a rectangle. The long side of the rectangle is parallel to the column direction Y in which the multiple binding pads 01 are arranged. The short side of the rectangle is parallel to the row direction X in which the multiple binding pads 01 are arranged, that is, the short side of the outline of the binding pad 01 is a horizontal straight line. It should be noted that the straight line parallel to the row direction X is a horizontal straight line.

[0037] The short sides of two adjacent rows of binding pads 01 are opposite; specifically, any two opposite binding pads 01 in two adjacent rows are respectively defined as the first pad A and the second pad B, the short side of the first pad A adjacent to the second pad B is defined as the short side a, the short side of the second pad B adjacent to the first pad A is defined as the short side b, and the orthographic projection of the short side a on the second pad B along the column direction Y can coincide with the short side b, so that the short side a of the first pad A is opposite to the short side b of the second pad B.

[0038] During the binding process of the binding pad 01 of the binding part, hot pressing is usually required. During the hot pressing process, the first pad A and the second pad B are simultaneously subjected to pressure and deformed along their long sides. The area between the short side a of the first pad A and the short side b of the second pad B has nowhere to release the extrusion deformation on both sides of the first pad A and the second pad B. The deformation accumulates in the area between the short side a and the short side b, resulting in a larger deformation of the area between the short side a and the short side b, thereby forming a crack, and even a horizontal through-type crack C.

[0039] The short side relative area between two adjacent rows of binding pads 01 (i.e., the area between short side a and short side b) undergoes a large deformation during the hot pressing process, so that the connecting wire 02 located in the short side relative area between two adjacent rows of binding pads 01 is at risk of breaking, and thus the display panel is at risk of display abnormality. It should be noted that the connecting wire 02 located in the short side relative area between two adjacent rows of binding pads 01 can extend in the direction from one row of binding pads 01 to another row of binding pads 01, or can extend in a direction intersecting with the direction from one row of binding pads 01 to another row of binding pads 01, both of which are at risk of breaking.

[0040] In view of this, the embodiments of the present application provide a display panel and an electronic device, which reduce the risk of breakage of the connecting wire during the binding process of the binding part.

[0041] See also Figures 3 to 5 , Figure 3 is a schematic diagram of a top view of the panel portion and the binding portion of the display panel provided in an embodiment of the present application, Figure 4 yes Figure 3 The structural diagram of the first embodiment of the first binding pad of the binding part shown in FIG. Figure 5 yes Figure 4 The diagram shows the forces acting on the binding part during the binding process.

[0042] The display panel includes a panel portion 10 and a binding portion 20. The binding portion 20 is provided on the side of the panel portion 10. The panel portion 10 is used to display images. The binding portion 20 refers to an area for electrically connecting the panel portion 10 with other electronic components. The binding portion 20 includes a plurality of first binding pads 21; the first binding pads 21 are interfaces for realizing electrical connection between the panel portion 10 and other electronic components. The plurality of first binding pads 21 are arranged in a plurality of rows and columns, and there is a spacing between the first binding pads 21 in two adjacent rows, and there is a spacing between the first binding pads 21 in two adjacent columns, so as to reduce interference between the first binding pads 21 during the binding process and maintain the reliability of the electrical connection between the panel portion 10 and other electronic components. The binding portion 20 also includes a first connecting wire 22, which is used to connect the first binding pad 21 with the panel portion 10 to realize electrical connection between the panel portion 10 and the first binding pad 21.

[0043] In this embodiment, the contour of the first binding pad 21 is in the shape of a long strip; specifically, the contour of the first binding pad 21 is a shape in which the length exceeds the width, presenting a long, narrow or slender appearance. The contour of the first binding pad 21 includes a first side and a second side that are arranged opposite to each other, the arrangement direction of the first side and the second side is the same as the direction in which the binding portion 20 points to the panel portion 10, and the first side and / or the second side intersects with the row direction X in which the plurality of first binding pads 21 are arranged.

[0044] By designing the first side and / or the second side of the contour of the first binding pad 21 to intersect with the row direction X in which the plurality of first binding pads 21 are arranged, the first side and / or the second side of the contour of the first binding pad 21 are arranged non-parallel to the row direction X in which the plurality of first binding pads 21 are arranged, that is, the first side and / or the second side of the contour of the first binding pad 21 is in the shape of a non-horizontal straight line, which is conducive to dispersing the thermal compression stress during the binding process, reducing the deformation of the relative area between the first side of a row of first binding pads 21 and the second side of the first binding pads of another row during the hot pressing process, reducing the cracks formed in the relative area between the first side of a row of first binding pads 21 and the second side of the first binding pads of another row, thereby reducing the risk of fracture of the first connection line 22 located in the relative area between the first side of a row of first binding pads 21 and the second side of the first binding pads of another row, which is conducive to maintaining a good display effect of the display panel. In this embodiment, a straight line parallel to the row direction X is defined as a horizontal straight line, and a line other than a horizontal straight line is defined as a non-horizontal straight line. The row direction X is perpendicular to the direction in which the binding portion 20 points to the panel portion 10, and the column direction Y is the same as the direction in which the binding portion 20 points to the panel portion 10. It should be noted that the relative area between the first side of the first binding pads 21 of one row and the second side of the first binding pads of another row can also be referred to as the side relative area of ​​the first binding pads 21 of two adjacent rows.

[0045] For example, Figure 4 As shown, any two opposite first binding pads 21 in two adjacent rows of first binding pads 21 are defined as first pad M and second pad N respectively; in other words, along the column direction Y in which the plurality of first binding pads 21 are arranged, any two adjacent first binding pads 21 are defined as first pad M and second pad N respectively. The side of the first pad M adjacent to the second pad N is the first side, defined as side m; the side of the second pad N adjacent to the first pad M is the second side, defined as side n. The orthographic projection of the two opposite sides of the first pad M arranged along the row direction on the second pad N along the column direction Y may overlap with the two opposite sides of the second pad N arranged along the row direction. At this time, the side m of the first pad M is opposite to the side n of the second pad N. The area between the side m and the side n is the relative area between the first side of the first pad M and the second side of the second pad N.

[0046] During the hot-pressing binding process of the binding portion 20, since the first side and / or the second side of the first binding pad 21 intersects with the row direction X in which the plurality of first binding pads 21 are arranged, that is, the side m of the first pad M and the side n of the second pad N intersect with the row direction X in which the plurality of first binding pads 21 are arranged, respectively, the side m of the first pad M and the side n of the second pad N are non-horizontal straight lines, which are conducive to dispersing the hot-pressing stress and reducing the excessive concentration of stress, and the deformation of the area between the side m of the first pad M and the side n of the second pad N is small (e.g., Figure 5 As shown), the risk of breaking of the first connecting line 22 in the area between the edge m and the edge n is reduced, that is, the risk of breaking of the first connecting line 22 in the relative area between the first edge of one row of first binding pads 21 and the second edge of another row of first binding pads 21 is reduced.

[0047] It should be noted that Figure 2 The short side of the binding pad is parallel to the row direction in which the plurality of binding pads are arranged, that is, the short side of the binding pad is a horizontal straight line; Figure 5 The first side and / or the second side of the first binding pad 21 in the embodiment intersects with the row direction in which the plurality of first binding pads 21 are arranged, that is, the first side and / or the second side of the first binding pad 21 is a non-horizontal straight line; by comparing Figure 2 and Figure 5 Designing the first side and / or the second side of the first binding pad 21 as a non-horizontal straight line can reduce the deformation of the area between the side m of the first pad M and the side n of the second pad N, reduce the crack or crack length between the side m of the first pad M and the side n of the second pad N, and thereby reduce the risk of breakage of the first connecting line 22 in the relative area between the first side of one row of first binding pads 21 and the second side of another row of first binding pads 21.

[0048] In addition, continue to read Figure 4 , the side m of the first pad M and the side n of the second pad N respectively intersect with the row direction X in which the multiple first binding pads 21 are arranged, the side m of the first pad M and the side n of the second pad N are non-horizontal straight lines, relative to the side m and the side n being horizontal straight lines, the area where cracks are generated in the relative area between the side m and the side n between two adjacent rows of first binding pads 21 is reduced from O1 to O2, which is beneficial to reducing the crack length caused by deformation in the relative area between the side m and the side n between two adjacent rows of first binding pads 21. The smaller the crack length, the greater the energy required for crack expansion, which reduces the expansion of the crack along the row direction X, reduces the probability of through-type cracks, and reserves more available space for the first connecting line 22.

[0049] In one embodiment, along the row direction X in which the plurality of first binding pads 21 are arranged, the first sides of two adjacent first binding pads 21 are staggered, and / or the second sides of two adjacent first binding pads 21 are staggered, so that the first sides of any two adjacent first binding pads 21 in the same row are no longer on the same horizontal straight line, and the second sides of any two adjacent first binding pads 21 in the same row are no longer on the same horizontal straight line. This can prevent cracks formed in the relative area between the first sides of one row of first binding pads 21 and the second sides of another row of first binding pads 21 in the column direction Y from extending along the row direction X to the non-relative area, thereby reducing the probability of forming horizontal through-type cracks, and reducing the risk of breaking the first connecting line 22 located between two adjacent rows of first binding pads 21 and in the relative area of ​​the edges of two non-adjacent rows of first binding pads 21 (i.e., the relative area between the first sides of first binding pads 21 in non-one row and the second sides of first binding pads 21 in another row).

[0050] Among them, the horizontal through-type crack refers to a crack extending from the first end of the binding portion 20 to the second end opposite to the first end along the row direction X. The staggered setting between the first edges of two adjacent first binding pads 21 in the row direction X refers to the staggered setting of the first edges of the first binding pads 21 at the same position, which can also be understood as the non-aligned arrangement of the two adjacent first binding pads 21 in the row direction X, or as the partial offset of the two adjacent first binding pads 21 in the row direction X in the column direction Y. The first edges of the two adjacent first binding pads 21 in the row direction X can be partially misaligned or completely misaligned, so that the first edges of any two adjacent first binding pads 21 in the same row are no longer on the same horizontal straight line. The staggered setting between the second edges of the two adjacent first binding pads 21 in the row direction X is the same as above and will not be repeated.

[0051] For example, Figure 4 As shown, the first side and the second side of each first binding pad 21 are both short sides of its outline. Each first binding pad 21 includes a first short side (i.e., the first side) and a second short side (i.e., the second side) that are relatively arranged. The first short sides of any two adjacent first binding pads 21 in the row direction X are staggered, and the second short sides are staggered. Any two first binding pads 21 in the row direction X are defined as the third pad P and the fourth pad Q, respectively. The fourth pad Q can be translated upward along the column direction Y relative to the third pad P, or can be translated downward along the column direction Y relative to the third pad P, so that the short sides of the third pad P and the fourth pad Q are staggered.

[0052] It can be understood that by setting the first side and / or the second side of the first binding pad 21 to intersect with the row direction X in which the multiple first binding pads 21 are arranged, the risk of breaking the first connecting line 22 in the relative area between the first side of one row of first binding pads 21 and the second side of the first binding pad 21 in another row can be reduced; by setting the staggered setting between the first sides of two adjacent first binding pads 21 in the row direction X and the staggered setting between the second sides of two adjacent first binding pads 21 in the row direction X, the risk of breaking the first connecting line 22 in the non-edge relative area of ​​the first binding pads 21 of two adjacent rows can be reduced; setting the first side and / or the second side of the first binding pad 21 to intersect with the row direction X in which the multiple first binding pads 21 are arranged, and at the same time setting the staggered setting between the first sides of two adjacent first binding pads 21 in the row direction X and / or the staggered setting between the second sides of two adjacent first binding pads 21 in the row direction X, the risk of breaking the first connecting line 22 located between the first binding pads 21 of two adjacent rows is reduced.

[0053] Optionally, along the row direction X where the plurality of first binding pads 21 are arranged, the offset distance between the first sides of two adjacent first binding pads 21 is greater than the processing tolerance of the first binding pads 21, thereby reducing the risk of no offset setting between the first sides of two adjacent first binding pads 21 in the row direction X due to the processing technology, and maintaining the offset setting between the first sides of two adjacent first binding pads 21 in the row direction X, which is conducive to reducing the risk of breakage of the first connection line 22 located between two adjacent rows of first binding pads 21. Along the row direction X where the plurality of first binding pads 21 are arranged, the offset distance between the second sides of two adjacent first binding pads 21 is set as above and will not be repeated.

[0054] See also Figure 6 , Figure 6 yes Figure 3 The structure diagram of the second embodiment of the first binding pad of the binding part is shown.

[0055] In one embodiment, two adjacent rows of first binding pads 21 are defined as a first row of pads L1 and a second row of pads L2, respectively, and the edge of the first row of pads L1 adjacent to the second row of pads L2 and the edge of the second row of pads L2 adjacent to the first row of pads L1 are completely misaligned. Wherein, the edge of the first row of pads L1 adjacent to the second row of pads L2 and the edge of the second row of pads L2 adjacent to the first row of pads L1 are completely misaligned, which means that the orthographic projection of the edge of the first binding pad 21 of the first row of pads L1 adjacent to the second row of pads L2 along the column direction Y on the second row of pads L2 has no overlapping part with the edge of the first binding pad 21 of the second row of pads L2 adjacent to the first row of pads L1. Exemplarily, the edge of the first row of pads L1 adjacent to the second row of pads L2 is the first edge of the first binding pad 21 of the first row of pads L1, and the edge of the second row of pads L2 adjacent to the first row of pads L1 is the second edge of the first binding pad 21 of the second row of pads L2.

[0056] By completely staggering the edges of the first row of pads L1 adjacent to the second row of pads L2 and the edges of the second row of pads L2 adjacent to the first row of pads L1, there is no relative edge area between any two adjacent rows of first binding pads 21 in the binding portion 20 (that is, there is no relative area between the first edges of the first binding pads 21 in one row and the second edges of the first binding pads 21 in another row). In addition, there is no situation in which both ends of the relative edge areas of the two adjacent rows of first binding pads 21 are squeezed and deformed at the same time and have nowhere to release, resulting in deformation accumulation during the binding process. This reduces the probability of the first connecting line 22 between the two adjacent rows of first binding pads 21 breaking, which is conducive to achieving a better display effect.

[0057] It should be noted that the first row of pads L1 and the second row of pads L2 respectively include a plurality of first binding pads 21, and the edges of the plurality of first binding pads 21 of the first row of pads L1 adjacent to the second row of pads L2 are completely misaligned with the edges of the plurality of first binding pads 21 of the second row of pads L2 adjacent to the first row of pads L1. It can also be understood that the second row of pads L2 is translated to the left or to the right along the row direction X relative to the first row of pads L1, so that the edges of the first row of pads L1 adjacent to the second row of pads L2 are completely misaligned with the edges of the second row of pads L2 adjacent to the first row of pads L1, and the edges of the plurality of first binding pads 21 of the first row of pads L1 are completely misaligned with the edges of the plurality of first binding pads 21 of the second row of pads L2.

[0058] For example, Figure 6As shown, the first binding pads 21 of odd rows are aligned, and the first binding pads 21 of even rows are aligned; along the column direction Y, two opposite first binding pads 21 are spaced one row apart, and the spacing distance is relatively large. During the binding process, the deformation caused by the simultaneous squeezing of the two ends of the area between the two opposite first binding pads 21 is relatively small, and deformation accumulation is not likely to occur, thereby reducing the generation of cracks, and thereby reducing the risk of breakage of the first connecting line 22 between the two opposite first binding pads 21 in the column direction Y.

[0059] Optionally, the misalignment distance between the edge of the first row of pads L1 adjacent to the second row of pads L2 and the edge of the second row of pads L2 adjacent to the first row of pads L1 is greater than the processing tolerance of the first binding pads 21, thereby reducing the risk of the edge of the first row of pads L1 adjacent to the second row of pads L2 and the edge of the second row of pads L2 adjacent to the first row of pads L1 not being completely misaligned due to the processing technology, which helps to reduce the risk of breakage of the first connecting line 22 located between two adjacent rows of first binding pads 21.

[0060] See also Figure 7 , Figure 7 yes Figure 3 The structure diagram of the first binding pad of the binding part in the third embodiment is shown.

[0061] In one embodiment, if Figure 7 As shown, along the row direction X in which the plurality of first binding pads 21 are arranged, the first sides of two adjacent first binding pads 21 are staggered, and / or the second sides of two adjacent first binding pads 21 are staggered; at the same time, the two adjacent rows of first binding pads 21 are defined as the first row pads L1 and the second row pads L2, respectively, and the side of the first row pad L1 adjacent to the second row pad L2 and the side of the second row pad L2 adjacent to the first row pad L1 are completely staggered. Through the above arrangement, the deformation accumulation between the first binding pads 21 of two adjacent rows during the binding process is significantly reduced, which is conducive to reducing the risk of the first connecting line 22 breaking.

[0062] See also Figures 8 to 12 , Figure 8 yes Figure 3 The structural diagram of the first binding pad of the binding portion in the fourth embodiment is shown, Fig. 9 yes Figure 3 The structural diagram of the first binding pad of the binding portion in the fifth embodiment is shown, Fig.10 yes Figure 3 The structural diagram of the first binding pad of the binding portion in the sixth embodiment is shown, Fig.11 yes Figure 3 The structural diagram of the seventh embodiment of the first binding pad of the binding portion shown in FIG. Fig.12 yes Figure 3The structure diagram of the first binding pad of the binding part in the eighth embodiment is shown.

[0063] In one embodiment, the first side shape of the contour of the first binding pad 21 is one of a folded line, an oblique line, and a curve; and / or the second side shape of the contour of the first binding pad 21 is one of a folded line, an oblique line, and a curve. By designing the first side and / or the second side of the contour of the first binding pad 21 to be one of a folded line, an oblique line, and a curve, the first side and / or the second side of the contour of the first binding pad 21 intersects with the row direction X in which the plurality of first binding pads 21 are arranged, and the first side and / or the second side are non-horizontal straight lines, which is conducive to dispersing the thermal pressure stress during the binding process.

[0064] Optionally, when the first side of the outline of the first binding pad 21 is a fold line, the fold line has at least one inflection point, which is specifically designed according to needs. Figure 4 As shown, the first side of the outline of the first binding pad 21 is a broken line, and the broken line has an inflection point. Figure 8 As shown, the first side of the outline of the first binding pad 21 is a broken line with three inflection points. The second side of the outline of the first binding pad 21 can be arranged in the same manner, which will not be described in detail.

[0065] Optionally, when the first side of the outline of the first binding pad 21 is an oblique line, the angle formed between the oblique line and the row direction X in which the plurality of first binding pads 21 are arranged is greater than 0 degrees and less than 90 degrees. Fig. 9 As shown, the first side and the second side of the outline of the first binding pad 21 are both oblique lines, the first side and the second side are inclined in the same direction, and the angle α formed between the oblique line and the row direction X is 45 degrees. Fig.10 As shown, the two opposite first and second sides of the outline of the first binding pad 21 are both oblique lines, the first and second sides have different inclination directions, and the angles α formed between the first and second sides and the row direction X are both 45 degrees.

[0066] Optionally, when the first side of the outline of the first binding pad 21 is a curve, the first side is a continuous, smooth, curved line. Fig.11 As shown, the first side of the outline of the first binding pad 21 is a curve. The second side of the outline of the first binding pad 21 can be arranged in the same manner, which will not be described in detail.

[0067] In one embodiment, the shape of the first side and the shape of the second side are independently selected from one of a fold line, an oblique line, and a curve, and the shape of the first side and the shape of the second side may be the same or different. The shape of the first side is the same as the shape of the second side, which helps to reduce the difficulty of processing. For example, Figure 4 , Figures 6 to 12As shown, the shape of the first side of the first binding pad 21 is the same as the shape of the second side.

[0068] In one embodiment, the first side and the second side are arranged in parallel; or, the contour of the first binding pad 21 also includes a third side and a fourth side arranged opposite to each other, the third side connects the first side and the second side, and the fourth side connects the first side and the second side; the first side and the second side are arranged symmetrically along the midline of the third side of the first binding pad 21, which can achieve a better thermal pressure stress dispersion effect. For example, Fig. 9 As shown, the first side is arranged parallel to the second side. Figure 4 , Figure 6 , Figure 7 , Figure 8 , Fig.10 , Fig.11 , Fig.12 As shown, the first side and the second side are symmetrically arranged along the midline in the direction of the third side of the first binding pad 21 .

[0069] In one embodiment, the outline of the first binding pad 21 further includes a third side and a fourth side that are arranged opposite to each other, the third side connects the first side and the second side, and the fourth side connects the first side and the second side; the extension direction of the third side and the fourth side is parallel to the column direction Y in which the plurality of first binding pads 21 are arranged, so that more available space is reserved for the first connection line 22. For example, Figure 4 , Figures 6 to 11 As shown, when the column direction Y is perpendicular to the row direction X, the extension direction of the third side and the extension direction of the fourth side of the outline of the first binding pad 21 are perpendicular to the row direction X in which the plurality of first binding pads 21 are arranged. Fig.12 As shown, when the column direction Y is not perpendicular to the row direction X, the extension direction of the third side and the extension direction of the fourth side of the outline of the first binding pad 21 are not perpendicular to the row direction X in which the multiple first binding pads 21 are arranged, and the angle between the extension direction of the third side and the extension direction of the fourth side of the outline of the first binding pad 21 and the row direction X in which the multiple first binding pads 21 are arranged is the same as the angle between the column direction Y and the row direction X.

[0070] In one embodiment, the contour shape of each first binding pad 21 is the same, which helps to reduce the difficulty of processing. Figure 4 , Figures 6 to 12 As shown, the contour shape of each first binding pad 21 is the same. It can be understood that some of the contour shapes of the plurality of first binding pads 21 may be different, and the design and arrangement are specifically performed according to the needs.

[0071] In one embodiment, the first connecting line 22 is disposed between two adjacent columns of first binding pads 21, avoiding disposing the first connecting line 22 in the side relative region of two adjacent rows of first binding pads 21. Even if the first connecting line 22 is disposed between two adjacent rows of first binding pads 21, the first connecting line 22 is located in the non-side relative region of the two adjacent rows of first binding pads 21. It can be understood that the side relative region between two adjacent rows of first binding pads 21 is prone to deformation during the binding hot pressing process, and the side relative region between two adjacent rows of first binding pads 21 is prone to cracks during the binding hot pressing process. The first connecting line 22 is disposed avoiding the side relative region between the first binding pads 21, that is, the first connecting line 22 is disposed in the region of the binding portion 20 where cracks are not likely to occur, which helps to reduce the risk of the first connecting line 22 breaking. For example, as Figure 4 , Figures 8 to 11 As shown, the first connection line 22 is disposed between two adjacent columns of first binding pads 21 .

[0072] See also Fig.13 , Fig.13 It is a structural diagram of the positional relationship between the panel part, the binding part, and the control panel of the display panel of the embodiment of the present application.

[0073] The display panel also includes a control board 30, which is arranged opposite to the binding portion 20. The control board 30 includes a plurality of second binding pads, which are arranged corresponding to the first binding pads 21, and the orthographic projection of the second binding pads on the binding portion 20 overlaps at least partially with the first binding pads 21, so as to realize the connection between the second binding pads and the first binding pads 21. There is a one-to-one correspondence between the plurality of second binding pads of the control board 30 and the plurality of first binding pads 21 of the binding portion 20, so as to realize the binding connection between the control board 30 and the binding portion 20.

[0074] The control board 30 further includes a second connection line connected to the second binding pad.

[0075] Optionally, the contour shape of the second binding pad is the same as the contour shape of the first binding pad 21, and the arrangement of the multiple second binding pads is the same as the arrangement of the multiple first binding pads 21; that is, the setting method of the second binding pad on the control board 30 refers to the setting method of the first binding pad 21 on the binding part 20, and the same technical effect as the setting method of the first binding pad 21 can be achieved, and the probability of the second connecting line on the control board 30 breaking can be reduced.

[0076] Optionally, the second connection line on the control board 30 may be arranged in accordance with the arrangement of the first connection line 22 on the binding portion 20 . For example, the second connection line is arranged between two adjacent columns of second binding pads, which can reduce the probability of the second connection line on the control board 30 breaking.
