All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications also change accordingly.

For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or components inherent to the process, method, product or device.

[0032] In this document, the term "embodiment" means that the specific features, structures or characteristics described in connection with the embodiment can be included in at least one embodiment of the present application. The appearance of the phrase in the specification does not necessarily mean the same embodiment, nor is it an independent or alternative embodiment to other embodiments. It is explicitly and implicitly understood by a person of ordinary skill in the art that the embodiments described herein can be combined with other embodiments.

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

[0034] Referring to Figure 1 and Figure 2 , Figure 1 is a schematic view of a partial structure of a binding portion in the prior art, Figure 2 is Figure 1 is a schematic view of a force during a binding process of the binding portion.

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

[0036] The contour of the binding pad 01 is generally rectangular. The long side of the rectangle is parallel to the column direction Y in which the plurality of binding pads 01 are arranged. The short side of the rectangle is parallel to the row direction X in which the plurality of binding pads 01 are arranged, i.e., the short side of the contour 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 the plurality of binding pads 01 are opposite to each other. Specifically, two opposite binding pads 01 of the two adjacent rows of the plurality of binding pads 01 are defined as a first pad A and a second pad B, respectively. The short side of the first pad A adjacent to the second pad B is defined as a short side a, and the short side of the second pad B adjacent to the first pad A is defined as a short side b. The orthogonal projection of the short side a of the first pad 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 pads 01 of the binding portion, heat pressing is generally required. During the heat pressing process, the first pad A and the second pad B are simultaneously subjected to pressure and are deformed along the long side direction thereof. The area between the short side a of the first pad A and the short side b of the second pad B cannot release the deformation due to the extrusion deformation of the first pad A and the second pad B, and the deformation accumulates in the area between the short side a and the short side b, resulting in a large deformation in the area between the short side a and the short side b, and further forming a crack, even a horizontal through crack C.

[0039] The short side opposite area between two adjacent rows of the binding pads 01 (that is, the area between the short side a and the short side b) is deformed greatly during the hot pressing process, so that the connection line 02 located in the short side opposite area between two adjacent rows of the binding pads 01 is at risk of breaking, and in turn the display panel is at risk of display abnormality. It should be noted that the connection line 02 located in the short side opposite area between two adjacent rows of the binding pads 01 can extend in a direction pointing from one row of the binding pads 01 to another row of the binding pads 01, or extend in a direction intersecting the direction pointing from one row of the binding pads 01 to another row of the binding pads 01, and both 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 breaking of the connection line during the binding process of the binding part.

[0041] Please refer to Figures 3 to 5 , Figure 3 is a top view structural schematic diagram of a panel part and a binding part of a display panel provided by the embodiments of the present application, Figure 4 is Figure 3 a structural schematic diagram of a first binding pad of the first embodiment of the binding part shown in Figure 5 is Figure 4 a force schematic diagram during the binding process of the binding part shown in.

[0042] The display panel includes a panel part 10 and a binding part 20. The binding part 20 is arranged at a side edge of the panel part 10. The panel part 10 is used for displaying an image. The binding part 20 refers to an area for electrically connecting the panel part 10 and other electronic elements. The binding part 20 includes a plurality of first binding pads 21; the first binding pad 21 is an interface for electrically connecting the panel part 10 and other electronic elements. The plurality of first binding pads 21 are arranged in multiple rows and multiple columns, there is a spacing between two adjacent rows of the first binding pads 21, and there is a spacing between two adjacent columns of the first binding pads 21, which reduces interference between the first binding pads 21 during the binding process and maintains the reliability of the electrical connection between the panel part 10 and other electronic elements. The binding part 20 further includes a first connection line 22, which is used for connecting the first binding pad 21 and the panel part 10, and realizing the electrical connection between the panel part 10 and the first binding pad 21.

[0043] In the embodiments, the profile of the first binding pad 21 is in a long strip shape; specifically, the profile of the first binding pad 21 is a shape with a length greater than a width, presenting a long and narrow or elongated appearance. The profile of the first binding pad 21 includes oppositely arranged first and second edges, the arrangement direction of the first and second edges is the same as the direction in which the binding part 20 points to the panel part 10, and the first edge and / or the second edge intersects the row direction X in which the plurality of first binding pads 21 are arranged.

[0044] By designing the first and / or second sides of the first bonding pads 21 to intersect the row direction X in which the plurality of first bonding pads 21 are arranged, the first and / or second sides of the first bonding pads 21 are arranged non-parallel to the row direction X in which the plurality of first bonding pads 21 are arranged. That is, the first and / or second sides of the first bonding pads 21 are shaped as non-horizontal straight lines. This facilitates distributing thermal compression stress during the bonding process, reduces deformation of the opposing regions between the first sides of one row of first bonding pads 21 and the second sides of another row of first bonding pads during the thermal compression process, reduces crack formation in the opposing regions between the first sides of one row of first bonding pads 21 and the second sides of another row of first bonding pads, and thereby reduces the risk of fracture of the first connecting wires 22 in the opposing regions between the first sides of one row of first bonding pads 21 and the second sides of another row of first bonding pads, thereby facilitating maintaining a good display quality of the display panel. In this embodiment, straight lines parallel to the row direction X are defined as horizontal straight lines, and lines other than horizontal straight lines are defined as non-horizontal straight lines. The row direction X is perpendicular to the direction in which the binding portion 20 points toward the panel portion 10, and the column direction Y is the same as the direction in which the binding portion 20 points toward the panel portion 10. It should be noted that the opposing area between the first edge of the first binding pads 21 in one row and the second edge of the first binding pads in another row may also be referred to as the opposing edge area of ​​the first binding pads 21 in two adjacent rows.

[0045] For example, Figure 4 As shown, any two opposing 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 opposing sides of the first pad M arranged along the row direction onto the second pad N along the column direction Y may overlap with the two opposing sides of the second pad N arranged along the row direction. In this case, side m of the first pad M is opposite to side n of the second pad N. The area between side m and side n is the opposing area between the first side of the first pad M and the second side of the second pad N.

[0046] During the hot press bonding 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, the side m of the first pad M and the side n of the second pad N are non-horizontal straight lines. The non-horizontal straight lines are conducive to dispersing the hot press stress and reducing the excessive concentration of stress. 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 In addition, the first edge and / or the second edge of the first bonding pad 21 in the first bonding pad array 20 is designed as a non-horizontal straight line, which reduces the deformation of the area between the edge m of the first pad M and the edge n of the second pad N, reduces the crack or crack length between the edge m of the first pad M and the edge n of the second pad N, and further reduces the risk of fracture of the first connecting line 22 in the area between the edge m and the edge n, that is, the risk of fracture of the first connecting line 22 in the relative area between the first edge of a row of first bonding pads 21 and the second edge of another row of first bonding pads 21.

[0047] It should be noted that, Figure 2 The short edge of the bonding pad in the bonding pad array 20 is parallel to the row direction in which the plurality of bonding pads are arranged, that is, the short edge of the bonding pad is a horizontal straight line; Figure 5 The first edge and / or the second edge of the first bonding pad 21 in the first bonding pad array 20 intersects the row direction in which the plurality of first bonding pads 21 are arranged, that is, the first edge and / or the second edge of the first bonding pad 21 is a non-horizontal straight line; by comparison Figure 2 And Figure 5 Designing the first edge and / or the second edge of the first bonding pad 21 as a non-horizontal straight line can reduce the deformation of the area between the edge m of the first pad M and the edge n of the second pad N, reduce the crack or crack length between the edge m of the first pad M and the edge n of the second pad N, and further reduce the risk of fracture of the first connecting line 22 in the area between the first edge of a row of first bonding pads 21 and the second edge of another row of first bonding pads 21.

[0048] In addition, continuing to refer to Figure 4 The edge m of the first pad M and the edge n of the second pad N respectively intersect the row direction X in which the plurality of first bonding pads 21 are arranged, and the edge m of the first pad M and the edge n of the second pad N are non-horizontal straight lines. Compared with the horizontal straight line of the edge m and the edge n, the area generating a crack in the relative area of the edge m and the edge n between the two adjacent rows of first bonding pads 21 is reduced from O1 to O2, which is beneficial to reduce the crack length caused by deformation in the relative area of the edge m and the edge n between the two adjacent rows of first bonding pads 21. The smaller the crack length is, the more energy is required for crack propagation, which reduces the propagation of the crack along the row direction X, reduces the probability of the occurrence of a through crack, 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 breakage of the first connecting line 22 located between two adjacent rows of first binding pads 21 and in the relative area of ​​the sides of two non-adjacent rows of first binding pads 21 (that is, the relative area between the first sides of non-one row of first binding pads 21 and the second sides of non-one row of first binding pads 21).

[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 staggered or completely staggered, 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 set. 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 edge and / or the second edge of the first bonding pad 21 intersecting with the row direction X in which the plurality of first bonding pads 21 are arranged, the risk of breakage of the first connecting line 22 in the first edge and / or the second edge of the first bonding pad 21 opposite region of the first connecting line 22 in the first edge of the first bonding pad 21 of another row can be reduced; by setting the first edge of the first bonding pad 21 of the two adjacent first bonding pads 21 in the row direction X to be staggered, and the second edge of the first bonding pad 21 of the two adjacent first bonding pads 21 in the row direction X to be staggered, the risk of breakage of the first connecting line 22 in the non-edge opposite region of the first connecting line 22 between the two adjacent rows of first bonding pads 21 can be reduced; by setting the first edge and / or the second edge of the first bonding pad 21 intersecting with the row direction X in which the plurality of first bonding pads 21 are arranged, and setting the first edge of the first bonding pad 21 of the two adjacent first bonding pads 21 in the row direction X to be staggered, and / or the second edge of the first bonding pad 21 of the two adjacent first bonding pads 21 in the row direction X to be staggered, the risk of breakage of the first connecting line 22 between the two adjacent rows of first bonding pads 21 can be reduced.

[0053] Optionally, along the row direction X in which the plurality of first bonding pads 21 are arranged, the staggered interval between the first edges of the two adjacent first bonding pads 21 is greater than the processing tolerance of the first bonding pad 21, reducing the risk that the first edges of the two adjacent first bonding pads 21 in the row direction X are not staggered due to the processing process, maintaining the staggered arrangement between the first edges of the two adjacent first bonding pads 21 in the row direction X, and facilitating the reduction of the risk of breakage of the first connecting line 22 between the two adjacent rows of first bonding pads 21. The staggered interval between the second edges of the two adjacent first bonding pads 21 along the row direction X in which the plurality of first bonding pads 21 are arranged is set as above, and will not be repeated here.

[0054] Please refer to Figure 6 , Figure 6 is Figure 3 the structure schematic diagram of the first bonding pad of the binding part according to the second embodiment.

[0055] In an embodiment, two adjacent rows of the first bonding pads 21 are defined as a first row of pads L1 and a second row of pads L2 respectively, and 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. Here, the completely misaligned edges of the first row of pads L1 adjacent to the second row of pads L2 with the edges of the second row of pads L2 adjacent to the first row of pads L1 means that the first edges of the first bonding pads 21 of the first row of pads L1 adjacent to the second row of pads L2 have no overlapping part with the second edges of the first bonding pads 21 of the second row of pads L2 adjacent to the first row of pads L1 along the column direction Y. For example, the edges of the first row of pads L1 adjacent to the second row of pads L2 are the first edges of the first bonding pads 21 of the first row of pads L1, and the edges of the second row of pads L2 adjacent to the first row of pads L1 are the second edges of the first bonding pads 21 of the second row of pads L2.

[0056] By setting the edges of the first row of pads L1 adjacent to the second row of pads L2 completely misaligned with the edges of the second row of pads L2 adjacent to the first row of pads L1, there is no edge-to-edge area between any two adjacent rows of the first bonding pads 21 in the bonding part 20 (i.e., there is no edge-to-edge area between the first edges of the first bonding pads 21 of one row and the second edges of the first bonding pads 21 of another row), so there is no situation that the edge-to-edge area of the two adjacent rows of the first bonding pads 21 is simultaneously squeezed and deformed without releasing during the bonding process, which reduces the probability of breaking the first connecting lines 22 between the two adjacent rows of the first bonding pads 21, and 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 each include a plurality of first bonding pads 21, and the edges of the plurality of first bonding 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 bonding 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 shifted leftward or rightward relative to the first row of pads L1 along the row direction X, 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 bonding pads 21 of the first row of pads L1 are completely misaligned with the edges of the plurality of first bonding pads 21 of the second row of pads L2.

[0058] For example, the first row of pads L1 and the second row of pads L2 are completely misaligned along the row direction X, and the edges of the first row of pads L1 adjacent to the second row of pads L2 are the first edges of the first bonding pads 21 of the first row of pads L1, and the edges of the second row of pads L2 adjacent to the first row of pads L1 are the second edges of the first bonding pads 21 of the second row of pads L2. Figure 6As shown, the first binding pads 21 in odd rows are aligned, and the first binding pads 21 in even rows are aligned; along the column direction Y, the two opposite first binding pads 21 are spaced by one row, and the spacing distance is large, so that the deformation of the area between the two opposite first binding pads 21 is small during the binding process, and the deformation accumulation is not easy to occur, thereby reducing the crack and the risk of breaking of the first connecting line 22 between the two opposite first binding pads 21 along 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 machining tolerance of the first binding pad 21, thereby reducing the risk that 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 not completely misaligned due to the machining process, and facilitating reduction of the risk of breaking of the first connecting line 22 between the two adjacent rows of first binding pads 21.

[0060] Please refer to Figure 7 , Figure 7 is Figure 3 the structural schematic diagram of the first binding pad of the binding part of the seventh embodiment.

[0061] In an embodiment, as shown in Figure 7 , along the row direction X in which the plurality of first binding pads 21 are arranged, the first edges of the two adjacent first binding pads 21 are misaligned, and / or the second edges of the two adjacent first binding pads 21 are misaligned; meanwhile, the two adjacent rows of first binding pads 21 are defined as the first row of pads L1 and the second row of pads L2, 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. Through the above arrangement, the deformation accumulation between the two adjacent rows of first binding pads 21 during the binding process is obviously reduced, thereby facilitating reduction of the risk of breaking of the first connecting line 22.

[0062] Please refer to Figures 8 to 12 , Figure 8 is Figure 3 the structural schematic diagram of the first binding pad of the binding part of the fourth embodiment, Figure 9 is Figure 3 the structural schematic diagram of the first binding pad of the binding part of the fifth embodiment, Figure 10 is Figure 3 the structural schematic diagram of the first binding pad of the binding part of the sixth embodiment, Figure 11 is Figure 3 the structural schematic diagram of the first binding pad of the binding part of the seventh embodiment, Figure 12 is Figure 3Structure diagram of the first binding pad of the binding part of the eighth embodiment.

[0063] In an embodiment, the first edge of the contour of the first binding pad 21 is in one of a broken line, an oblique line, and a curved line; and / or, the second edge of the contour of the first binding pad 21 is in one of a broken line, an oblique line, and a curved line. By designing the first edge and / or the second edge of the contour of the first binding pad 21 to be in one of a broken line, an oblique line, and a curved line, the first edge and / or the second edge of the contour of the first binding pad 21 intersects with the row direction X of the plurality of first binding pads 21, and the first edge and / or the second edge is not a horizontal straight line, which facilitates dispersing the thermal stress in the binding process.

[0064] Optionally, when the first edge of the contour of the first binding pad 21 is a broken line, the broken line has at least one inflection point, which is specifically designed according to requirements. For example, as shown in FIG. 2A, the first edge of the contour of the first binding pad 21 is a broken line, and the broken line has one inflection point.

For example, as shown in FIG. 3A, the first edge and the second edge of the contour of the first binding pad 21 are both oblique lines, the oblique directions of the first edge and the second edge are the same, and the included angle α between the oblique lines and the row direction X is 45 degrees. Figure 9 As shown in FIG. 3B, the first edge and the second edge of the contour of the first binding pad 21 are both oblique lines, the oblique directions of the first edge and the second edge are different, and the included angles α between the oblique lines and the row direction X are both 45 degrees. Figure 10 As shown in FIG. 3C, the two opposite first edge and the second edge of the contour of the first binding pad 21 are both oblique lines, the oblique directions of the first edge and the second edge are different, and the included angles α between the oblique lines and the row direction X are both 45 degrees.

[0066] Optionally, when the first edge of the contour of the first binding pad 21 is a curved line, the first edge is a continuous, smooth, and curved line. For example, as shown in FIG. 4A, the first edge of the contour of the first binding pad 21 is a curved line. The second edge of the contour of the first binding pad 21 can be set in the same manner, which will not be described herein. Figure 11 As shown in FIG. 4B, the first edge of the contour of the first binding pad 21 is a curved line. The second edge of the contour of the first binding pad 21 can be set in the same manner, which will not be described herein.

[0067] In an embodiment, the shape of the first edge and the shape of the second edge are independently selected from one of a broken line, an oblique line, and a curved line, and the shape of the first edge and the shape of the second edge can be the same or different. The shape of the first edge and the shape of the second edge are the same, which facilitates reducing the processing difficulty. For example, as shown in FIG. 5A, the first edge and the second edge of the contour of the first binding pad 21 are both broken lines. Figure 4 , Figures 6 to 12As shown, the first edge of the first bonding pad 21 has the same shape as the second edge.

Exemplarily, as shown in Figure 9 As shown, the first edge and the second edge are arranged in parallel. Exemplarily, as shown in Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 10 、 Figure 11 、 Figure 12 As shown, the first edge and the second edge are symmetrically arranged along the middle line in the direction of the third edge of the first bonding pad 21.

[0069] In an embodiment, the profile of the first bonding pad 21 further comprises a third edge and a fourth edge arranged oppositely, the third edge connecting the first edge and the second edge, and the fourth edge connecting the first edge and the second edge; the extension direction of the third edge and the fourth edge is parallel to the column direction Y of the arrangement of the plurality of first bonding pads 21, which reserves more available space for the first connecting line 22. Exemplarily, as shown in 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 edge and the fourth edge of the profile of the first bonding pad 21 is perpendicular to the row direction X of the arrangement of the plurality of first bonding pads 21. Exemplarily, as shown in Figure 12 As shown, when the column direction Y is not perpendicular to the row direction X, the extension direction of the third edge and the fourth edge of the profile of the first bonding pad 21 is not perpendicular to the row direction X of the arrangement of the plurality of first bonding pads 21, and the included angle between the extension direction of the third edge and the fourth edge of the profile of the first bonding pad 21 and the row direction X of the arrangement of the plurality of first bonding pads 21 is the same as the included angle between the column direction Y and the row direction X.

[0070] In an embodiment, the profile of each first bonding pad 21 is the same, which is conducive to reducing the processing difficulty. Exemplarily, as shown in Figure 4 、 Figures 6 to 12 As shown, the profile of each first bonding pad 21 is the same. It can be understood that the profile of some of the plurality of first bonding pads 21 can be different, which is specifically designed and arranged according to the needs.

[0071] In an embodiment, the first connecting line 22 is arranged between two adjacent columns of the first binding pads 21, and the first connecting line 22 is arranged away from the edge-adjacent regions of the two adjacent rows of the first binding pads 21. That is, the first connecting line 22 is arranged in a region of the binding part 20 which is less likely to crack during the binding hot-pressing process, thereby reducing the risk of breakage of the first connecting line 22. Figure 4 、 Figures 8 to 11 As shown in FIGS. 2 and 3, the first connecting line 22 is arranged between two adjacent columns of the first binding pads 21.

The control board 30 includes a plurality of second binding pads arranged corresponding to the first binding pads 21, and the orthographic projection of the second binding pads on the binding part 20 at least partially overlaps the first binding pads 21, thereby realizing the connection between the second binding pads and the first binding pads 21. The plurality of second binding pads of the control board 30 and the plurality of first binding pads 21 of the binding part 20 are in one-to-one correspondence, thereby realizing the binding connection between the control board 30 and the binding part 20.

[0074] The control board 30 further includes a second connecting line connected with the second binding pads.

[0075] Optionally, the contour shape of the second binding pads is the same as that of the first binding pads 21, and the arrangement mode of the plurality of second binding pads is the same as that of the plurality of first binding pads 21. That is, the arrangement mode of the second binding pads on the control board 30 refers to that of the first binding pads 21 on the binding part 20, and the same technical effect as the arrangement mode of the first binding pads 21 can be realized, thereby reducing the probability of breakage of the second connecting line on the control board 30.

[0076] Optionally, the arrangement mode of the second connecting line on the control board 30 can refer to that of the first connecting line 22 on the binding part 20, for example, the second connecting line is arranged between two adjacent columns of the second binding pads, thereby reducing the probability of breakage of the second connecting line on the control board 30.
