     DETAILED DESCRIPTION 
     Hereinafter the present disclosure is further described in detail in conjunction with the drawings and embodiments. It is to be understood that the specific embodiments set forth below are merely intended to illustrate but not to limit the present disclosure. Additionally, it is to be noted that, for ease of description, only part, not all, of structures related to the present disclosure are illustrated in the drawings. 
       FIG.  1    is a diagram illustrating the structure of a display panel according to an embodiment of the present disclosure, and  FIG.  2    is a diagram illustrating the structure of another display panel according to an embodiment of the present disclosure. Referring to  FIG.  1    and  FIG.  2   , a display panel  10  provided in an embodiment of the present disclosure includes a display region  110  and a non-display region  120 . The non-display region  120  is located at least on a side of the display region  110 . The display panel  10  further includes multiple data lines  110 , multiple connection wires  200  and multiple signal wires  300 . The multiple connection wires  200  are electrically connected to the multiple data lines  100  and the multiple signal wires  300  respectively, the multiple data lines  100  and the multiple connection wires  200  are located in the display region  110 , and the multiple signal wires  300  are located in the non-display region  120 . The multiple connection wires  200  include a first connection wire group  210  and a second connection wire group  220 , where the first connection wire group  210  includes multiple first connection wires  211 , and the second connection wire group  220  includes multiple second connection wires  221 ; the first connection wire group  210  and the second connection wire group  220  are located on two sides of a first central axis a of the display panel  10  respectively, and the extension direction of the first central axis a is parallel to the extension direction of the multiple data lines  100 . The first connection wire group  210  and the second connection wire group  220  are disposed asymmetrically. 
     In an embodiment, the display panel  10  includes the display region  110  and the non-display region  120 . The display region  110  includes subpixels (not shown in the figures) and display signal lines, such as the data lines  100 , connected to the subpixels for implementing the display function of the display panel  100 . The non-display region  120  includes a display controller, such as a drive chip (not specifically shown in the figures), connected to the display signal lines, and provides display signals for the display signal lines through the display controller so as to drive the display panel  10  to achieve the display function. Referring to  FIG.  1    and  FIG.  2   , the non-display region  120  may be a lower bezel region located on a side of the display region  110 . The position relationship between the display region  110  and the non-display region  120  is not specifically limited in the embodiment of the present disclosure. 
     Further, referring to  FIG.  1    and  FIG.  2   , the display panel  100  includes multiple data lines  100 , multiple connection wires  200  and multiple signal wires  300 . The electrical connection between the data lines  100  and the signal wires  300  is achieved through the connection wires  200 , so that the normal transmission of data signals is ensured. The signal wires  300  are disposed in the non-display region  120 , and the data lines  100  are disposed in the display region  110 . Unlike the solution of disposing the connection wires  200  in the non-display region in the related art, to reduce the area of the non-display region  120  of the display panel  10 , that is, to improve the proportion of the display region  110  to the display panel  10 , the connection wires  200  are disposed in the display region  110  in the embodiment of the present disclosure, so as to effectively ensure the narrow bezel effect of the display panel  10 . 
     In an embodiment, the connection wires  200  include the first connection wire group  210  and the second connection wire group  220 , and the first connection wire group  210  and the second connection wire group  220  are located on two sides of the first central axis a of the display panel  10  respectively, so as to achieve the normal transmission of data signals of two sides of the display region  110  of the display panel  10 , and ensure the normal display of the display panel  10 . Further, the first connection wire group  210  includes multiple first connection wires  211 , and the second connection wire group  220  includes multiple second connection wires  221 . Referring to  FIG.  1    and  FIG.  2   , only part of the first connection wires  211  and second connection wires  221  are illustrated as an example in the figures, and the number of first connection wires  211  and the number of second connection wires  221  are not specifically limited in the embodiment of the present disclosure. Since the first connection wire group  210  and the second connection wire group  220  are disposed in the display region  110  of the display panel  10 , the connection wires  200  may be coupled with other wires (not specifically shown in the figures), for example, power supply signal lines, in the display panel  10 , that is, crosstalk between wires may be generated, affecting the display effect of the display panel  10 . In the embodiment of the present disclosure, the first connection wire group  210  and the second connection wire group  220  are disposed asymmetrically, that is, the positions for disposing the first connection wire group  210  and the second connection wire group  220  are adjusted, so as to reduce or balance crosstalk generated between the connection wires  200  and other signal lines in the display panel, and ensure the display effect of the display panel  10 . 
     In an embodiment, in the region for disposing the first connection wire group  210  in the display panel, crosstalk is more or less generated between the connection wires  200  and other signal lines in the region; if the position for disposing the second connection wire group  220  and the position for disposing the first connection wire group  210  are disposed symmetrically only for simplicity of the preparation process, the crosstalk generated between the connection wires  200  and other signal lines in this region will be amplified, which is not conducive to the smooth and balanced display of the display panel  10 . In the embodiment of the present disclosure, the first connection wire group  210  and the second connection wire group  220  are disposed asymmetrically about the first central axis a, so that coupling and crosstalk between the connection wires  200  and other signal lines in the region for disposing the connection wires  200  of the display panel  10  can be reduced or balanced, the stability of signal transmission in the display panel  10  can be improved, and the display balance of the display panel  10  can be improved, that is, the display effect of the display panel  10  can be improved. 
     In summary, for the display panel provided in the embodiment of the present disclosure, the connection wires include the first connection wire group and the second connection wire group located on two sides of the first central axis, the first connection wire group includes multiple first connection wires, and the second connection wire group includes multiple second connection wires; for the manner of disposing the connection wires, the first connection wire group and the second connection wire group are disposed asymmetrically about the first central axis, so that crosstalk generated between the connection wires and other wires in the display panel can be reduced or balanced, the display balance of the display panel is ensured, and thus the display effect of the display panel is improved. 
       FIG.  3    is a diagram illustrating the structure of another display panel according to an embodiment of the present disclosure. Referring to  FIG.  1    and  FIG.  3   , a first connection wire  211  includes a first wire section  211 A and a second wire section  211 B, where the first wire section  211 A and the second wire section  211 B are connected to each other, and the extension direction of the first wire section  211 A intersects the extension direction of the second wire section  211 B. A second connection wire  221  includes a third wire section  221 A and a fourth wire section  221 B, where the third wire section  221 A and the fourth wire section  221 B are connected to each other, and the extension direction of the third wire section  221 A intersects the extension direction of the fourth wire section  221 B. The extension direction of the third wire section  221 A is parallel to the extension direction of the first wire section  211 A, and the extension direction of the fourth wire section  221 B is parallel to the extension direction of the second wire section  211 B. The first connection wire group  210  includes V first connection wires  211 , and the second connection wire group  220  includes W second connection wires  221 , where a straight line where a first wire section  211 A of a v-th first connection wire  211  is located and a straight line where a third wire section  221 A of a w-th second connection wire  221  is located are symmetrical about the first central axis a. Along the extension direction X 1  of the data lines, a second wire section  211 B of the v-th first connection wire  211  and a fourth wire section  221 B of the w-th second connection wire  221  are disposed in a staggered manner, where V, W, v and w are each a positive integer, 1≤v≤V, and 1≤w≤W. 
     In an embodiment, referring to  FIG.  1    and  FIG.  3   , a first connection wire  211  includes a first wire section  211 A and a second wire section  211 B, and a second connection wire  221  includes a third wire section  221 A and a fourth wire section  221 B. Wire sections which are connected to each other and whose extension directions intersect are disposed, so that electrical connection in the display panel between the data lines  100  in the display region  110  and the signal wires  300  in the non-display region  120  is achieved through the connection wires  200 , various arrangements of the connection wires  200  are achieved through the adjustment on different wire sections, and the flexibility and diversity of the arrangements of the connection wires  200  are promoted. 
     Further, the first connection wire group  210  includes V first connection wires  211 , and the second connection wire group  220  includes W second connection wires  221 . The value of V and the value of W are not specifically limited in the embodiment of the present disclosure. Referring to  FIG.  1    and  FIG.  3   , the v-th first connection wire  211  in the first connection wire group  210  is shown as v in the figures, and the w-th second connection wire  221  in the second connection wire group  220  is shown as w in the figures. When the straight line where the first wire section  211 A of the v-th first connection wire  211  is located and the straight line where the third wire section  221 A of the w-th second connection wire  221  is located are symmetrical about the first central axis a, and V=W and v=w, referring to  FIG.  1   , the second wire section  211 B of the v-th first connection wire  211  and the fourth wire section  221 B of the w-th second connection wire  221  are disposed in a staggered manner along the extension direction X 1  of the data lines  100 , so that the asymmetrical arrangement of the first connection wire  211  and the second connection wire  221  is achieved. When V is not equal to W, the V first connection wires  211  and the W second connection wires  221  in the figures must be disposed asymmetrically. Further, the second wire section  211 B of the v-th first connection wire  211  and the fourth wire section  221 B of the w-th second connection wire  221  are disposed asymmetrically along the extension direction X 1  of the data lines  100 . In the figures, an example is illustrated where the second wire section  211 B of the v-th first connection wire  211  is located on a side of the fourth wire section  221 B of the w-th second connection wire  211  away from the non-display region  120 . 
     Further, referring to  FIG.  1    and  FIG.  3   , when the first wire section  211 A of the first connection wire  211  and the third wire section  221 A of the second connection wire  221  are asymmetrical about the first central axial a, the first connection wire  211  and the second connection wire  221  must be disposed asymmetrically. Further, referring to  FIG.  2   , when the first wire section  211 A of the first connection wire  211  and the third wire section  221 A of the second connection wire  221  are asymmetrical about the first central axial a, the extension length of the second wire section  211 B and the extension length of the fourth wire section  221 B may be adjusted to achieve the asymmetrical arrangement of the first connection wire  211  and the second connection wire  221 . Further, referring to  FIG.  1    and  FIG.  3   , when the first wire section  211 A of the first connection wire  211  and the third wire section  221 A of the second connection wire  221  are asymmetrical about the first central axial a, the position of a row where the second wire section  211 B is located and the position of a row where the fourth wire section  221 B is located may be adjusted to achieve the asymmetrical arrangement of the first connection wire  211  and the second connection wire  221 . In other words, in the first connection wire group  210  and the second connection wire group  220 , for two connection wires of which longitudinal (along the extension direction X 1  of the data lines  100 ) wire sections are disposed symmetrically about the first central axis a, transverse (along the arrangement direction X 3  of the data lines  100 ) wire sections corresponding to the two connection wires are not disposed in the same row. That is, a symmetrical and regular arrangement of the first connection wire group  210  and the second connection wire group  220  is broken, and thus the number of connection wires  200  and the number of other wires in the arrangement direction of the multiple data lines  100  are reduced. In this manner that the connection wires are not disposed in the same row, crosstalk generated by the same another wire on connection wires can further be reduced, for example, crosstalk generated on the same power supply signal line can be reduced, so that coupling fluctuation of signals between different wires is reversely reduced, the display balance of the display panel is ensured, and thereby the display effect of the display panel is improved. 
     In an embodiment, |V−W|≥1. 
     Referring to  FIG.  3   , the first connection wire group  210  includes V first connection wires  211 , and the second connection wire group  220  includes W second connection wires  221 , where |V−W|≥1. That is, the number of connection wires included in the first connection wire group  210  is different from the number of connection wires included in the second connection wire group  220 . In this manner, the arrangement of connection wires in the first connection wire group and the arrangement of connection wires in the second connection wire group can be further differentiated, the symmetrical and regular arrangement of the first connection wire group  210  and the second connection wire group  220  is further broken, and thus the number of connection wires  200  and the number of other wires in the arrangement direction of the multiple data lines  100  are reduced. As a result, for example, crosstalk generated on the same power supply signal line is reduced, so that the display balance of the display panel is ensured, and the display effect of the display panel  10  is improved. It is to be noted that an example is illustrated in  FIG.  3    where the first connection wire group  210  includes 8 first connection wires  211 , and the second connection wire group  210  includes 7 second connection wires  221 . In this case, V=8, and W=7. The number of connection wires in the first connection wire group  210  and the number of connection wires in the second connection wire group  220  are not specifically limited in the embodiment of the present disclosure. 
       FIG.  4    is an enlarged diagram of a region for disposing connection wires in  FIG.  1   , and  FIG.  5    is another enlarged diagram of the region for disposing the connection wires in  FIG.  1   . Referring to  FIG.  4    and  FIG.  5   , the display panel further includes multiple subpixels  400  located in the display region  110 , where the multiple subpixels  400  are arranged in an array. At least a row of subpixels  400  are disposed between any adjacent two second wire sections  211 B, and at least a row of subpixels  400  are disposed between any adjacent two fourth wire sections  221 B. Along the extension direction X 1  of the data lines  100 , straight lines where at least part of second wire sections  211 B are located are located between straight lines where adjacent two fourth wire sections  221 B are located, and straight lines where at least part of fourth wire sections  221 B are located are located between straight lines where adjacent two second wire sections  211 B are located. 
     The display region  110  includes multiple array subpixels  400 , and the subpixels  400  emit light by display signals provided by display signal lines to achieve the display function of the display panel  10 . The subpixels  400  include red subpixels, green subpixels and blue subpixels, and the type and arrangement of the subpixels  400  are not specifically limited in the embodiment of the present disclosure. 
     Further, at least a row of subpixels  400  are disposed between any adjacent two second wire sections  211 B, and at least a row of subpixels  400  are disposed between any adjacent two fourth wire sections  221 B. Referring to  FIG.  4   , a second wire section  211 B and a fourth wire section  221 B may separately be located between adjacent two rows of subpixels  400 . In this case, at least two rows of subpixels  400  may be disposed between adjacent two second wire sections  211 B, and at least two rows of subpixels  400  may be disposed between adjacent two fourth wire sections  221 B.  FIG.  4    illustrates an example where two rows of subpixels  400  are disposed between adjacent two second wire sections  211 B, and two rows of subpixels  400  are disposed between adjacent two fourth wire sections  221 B. Referring to  FIG.  5   , a second wire section  211 B overlaps subpixels  400  along the thickness direction (not shown in the figure) of the display panel  10 , and a fourth wire section  221 B overlaps subpixels  400  along the thickness direction (not shown in the figure) of the display panel  10 . In this case, at least a row of subpixels  400  may be disposed between adjacent two second wire sections  211 B, and at least a row of subpixels  400  may be disposed between adjacent two fourth wire sections  221 B.  FIG.  5    illustrates an example where a row of subpixels  400  are disposed between adjacent two second wire sections  211 B, and a row of subpixels  400  are disposed between adjacent two fourth wire sections  221 B. According to the preceding arrangement, in a case where the number of rows of subpixels  400  between adjacent two second wire sections  211 B is ensured to be at least one row, it is convenient to achieve that along the extension direction X 1  of the data lines  100 , straight lines where at least part of second wire sections  211 B are located are located between straight lines where adjacent two fourth wire sections  221 B are located. Similarly, in a case where the number of rows of subpixels  400  between adjacent two fourth wire sections  221 B is ensured to be at least one row, it is ensured that straight lines where at least part of second wire sections  211 B are located are located between straight lines where adjacent two fourth wire sections  221 B are located, that is, along the extension direction X 1  of the data lines  100 , second wire sections  211 B and fourth wire sections  221 B are alternately and cyclically arranged. In this manner, the symmetrical arrangement of the first connection wire group  210  and the second connection wire group  220  can be broken, and thus along the arrangement direction of the multiple data lines  100 , crosstalk generated between the connection wires  200  and other wires is reduced, the display balance of the display panel is ensured, and the display effect of the display panel is improved. 
     With continued reference to  FIG.  5   , the display panel further includes multiple subpixels  400  located in the display region  110 , where the multiple subpixels  400  are arranged in an array. Along the thickness direction (not shown in the figure) of the display panel  10 , the second wire section  211 B of the v-th first connection wire  211  (shown as v in the figure) overlaps a D-th row of subpixels (shown as D in the figure), and the fourth wire section  221 B of the w-th second connection wire  221  (shown as w in the figure) overlaps an E-th row of subpixels  400  (shown as E in the figure), where v=w, and D≠E. 
     In an embodiment, referring to  FIG.  5   , the v-th first connection wire  211  (shown as v in the figure) and the w-th second connection wire  221  are taken an example for illustration. The second wire section  211 B of the first connection wire  211  overlaps the D-th row of subpixels  400  along the thickness direction of the display panel  10 , and the fourth wire section  221 B overlaps the E-th row of subpixels  400  along the thickness direction of the display panel  10 , where v=w, and D≠E. For example, that is, the row of subpixels  400  where the third first connection wire  211  in the first connection wire group  210  is located is different from the row of subpixels  400  where the third second connection wire  221  in the second connection wire group  220  is located, that is, the second wire section  211 B of the first connection wire  211  and the fourth wire section  221 B of the second connection wire  221  are disposed in a staggered manner. In this manner, along the arrangement direction of the multiple data lines  100 , crosstalk generated between the connection wires  200  and other wires is reduced, and crosstalk is not generated on the same wire, that is, coupling fluctuation of data signals can also be reversely reduced, so that the display balance of the display panel is ensured, and thereby the display effect of the display panel is improved. Moreover, the first connection wires  211  and the second connection wires  221  disposed in the preceding manner makes the staggered arrangement simple. 
       FIG.  6    is a diagram illustrating the structure of another display panel according to an embodiment of the present disclosure. As shown in  FIG.  6   , along the direction X 2  from which the display region  110  points to the non-display region  120 , extension lengths of second wire sections  211 B gradually decrease, and extension lengths of fourth wire sections  221 B gradually decrease. 
     In an embodiment, as shown in  FIG.  6   , the display panel  10  further includes a power supply signal bus  500 A located in the non-display region  120  and power supply signal lines  500  connected to the power supply signal bus  500 A. Power supply signals flow from the non-display region  120  to the display region  110 . Since line resistance exists in the power supply signal lines  500 , in the display region  110 , power supply signals are relatively large in a region close to the non-display region  120 , so that the coupling effect between connection wires  200  and power supply signal lines  500  in this region is stronger, and crosstalk caused to the power supply signals in the power supply signal lines  500  is greater. Therefore, to ensure the overall signal transmission effect of the display panel  10 , that is, to reduce the overall crosstalk, the extension lengths of the second wire sections  211 B of the first connection wires  211  are adjusted, while the extension lengths of the fourth wire sections  221 B of the second connection wires  221  are also adjusted. 
     In an embodiment, along the direction X 2  from which the display region  110  points to the non-display region  120 , in a case where it is ensured that the first connection wire group  210  and the second connection wire group  220  are asymmetrical about the first central axis a, the extension lengths of the second wire sections  211 B and the extension lengths of the fourth wire sections  221 B gradually decrease, that is, extension lengths of positions where coupling crosstalk is likely to generate in the display panel  10  are reduced, so that the transmission stability and balance of signals in the wires in the display panel  10  are improved. 
       FIG.  7    is a diagram illustrating the structure of another display panel according to an embodiment of the present disclosure, and  FIG.  8    is a diagram illustrating the structure of another display panel according to an embodiment of the present disclosure. Referring to  FIG.  7    and  FIG.  8   , the display panel  10  further includes a first virtual wire group  230  and a second virtual wire group  240 . The first virtual wire group  230  includes multiple first virtual wires  231 , and the multiple first virtual wires  231  are located on a side of the second wire section  211 B away from the first central axis a; and along the direction X 2  from which the display region  112  points to the non-display region  120 , extension lengths of the multiple first virtual wires  231  gradually increase. The second virtual wire group  240  includes multiple second virtual wires  241 , and the multiple second virtual wires  241  are located on a side of the fourth wire section  221 B away from the first central axis a; and along the direction from which the display region  110  points to the non-display region  120 , extension lengths of the multiple second virtual wires  241  gradually increase. 
     The display panel  10  further includes the first virtual wire group  230  and the second virtual wire group  240 . The first virtual wire group  230  and the second virtual wire group  240  each includes multiple virtual wires, and the virtual wires do not affect the normal signal transmission in the display panel  10 . Referring to  FIG.  7    and  FIG.  8   , the first virtual wires  231  and the second virtual wires  241  are each disposed on a side away from the first central axis a compared with the connection wires  200 . 
     In an embodiment, based on the case where the extension lengths of the second wire sections  211 B and the extension lengths of the fourth wire sections  221 B gradually decrease along the direction X 2  from which the display region  110  points to the non-display region  120 , the first virtual wires  231  and the second virtual wires  241  are added, that is, the lengths of the second wire sections  211 B and the lengths of the fourth wire sections  221 B are compensated for, that is, the virtual wires are set to achieve the overall wiring balance of the region for disposing the connection wires  200 , so that the density balance of wires disposed in different regions is ensured; furthermore, it is avoided that the light reflectivity is different in different regions of the display panel  10  due to the imbalance wire setting, and that the display effect of the display panel  10  is imbalanced. 
     With continued reference to  FIG.  7   , the first virtual wires  231  and the second wire section  211 B are integrally disposed in the same layer; and the second virtual wires  241  and the fourth wire section  221 B are integrally disposed in the same layer. 
     The first virtual wires  231  and the second wire section  211 B are disposed in the same layer, and the second virtual wires  241  and the fourth wire section  221 B are disposed in the same layer, so that the thickness of the display panel  10  can be reduced, which is conducive to achieve the thin design of the display panel  10 . Further, based on the same-layer design, the first virtual wires  231  and the second wire section  211 B may be integrally designed, and the second virtual wires  241  and the fourth wire section  221 B may be integrally disposed, so that the preparation process of the display panel  10  can be reduced and the cost can be saved. Further, the virtual wires and the connection wires  200  are integrally disposed in the same layer, so that is can be avoided that via holes between the connection wires  200  and the data lines  100  are provided at the edge of the connection wires  200 , and thus the stability of the punching connection can be ensured. 
     In an embodiment, with continued reference to  FIG.  8   , the first virtual wires  231  and the second wire section  211 B are disposed insulated from each other in the same layer, and the second virtual wires  241  and the fourth wire section  221 B are disposed insulated from each other in the same layer; and the first virtual wires  231  and the second virtual wires  241  are connected to a fixed potential terminal. 
     The first virtual wires  231  and the second wire section  211 B are disposed in the same layer, and the second virtual wires  241  and the fourth wire section  221 B are disposed in the same layer, so that the thickness of the display panel  10  can be reduced, which is conducive to achieve the thin design of the display panel  10 . Further, based on the same-layer design, the first virtual wires  231  may also be disposed insulated from the second wire section  211 B, and the second virtual wires  241  may also be disposed insulated from the fourth wire section  221 B, that is, the first virtual wires  231  and the second virtual wires  241  are prevented from interfering with signals transmitted in the connection wires  200 . Further, to avoid inducing other signals and thus affecting the normal transmission of display signals when the first virtual wires  231  and the second virtual wires  241  are disposed in a floating manner, a potential adjustment may be performed on the first virtual wires  231  and the second virtual wires  241 . For example, the first virtual wires  231  and the second virtual wires  241  are connected to a fixe potential terminal, so that on the one hand, a fixed potential signal is transmitted on the first virtual wires  231  and the second virtual wires  241 , and the potential is not affected by other signals and does not interfere with other signals; on the other hand, when the virtual wires are electrically connected to the fixed potential terminal, the resistance loss during the transmission of signals in the wires provided by the fixed signal terminal can be reduced, and the signal transmission effect in the display panel  10  can be improved. 
     It is to be noted that the position for disposing the fixed potential terminal is not specifically limited in the embodiment of the present disclosure, and the fixed potential terminal may be a terminal providing a positive voltage signal or a terminal providing a negative voltage signal. 
     With continued reference to  FIG.  4   , the first connection wire group  210  includes an h-th first connection wire  211  (shown as h in the figure) and an i-th first connection wire  211  (shown as i in the figure). The data lines  100  include an m-th data line  100  (shown as m in the figure) and an n-th data line  100  (shown as n in the figure), and the m-th data line  100  and the n-th data line  100  are located on the same side of the first central axis a, where h≠i and h and i are each a positive integer, and m≠n and m and n are each a positive integer. The h-th first connection wire  211  (shown as h in the figure) is electrically connected to the m-th data line  100  (shown as m in the figure), and the i-th first connection wire  211  (shown as i in the figure) is electrically connected to the n-th data line  100  (shown as n in the figure). A first wire section  211 A of the h-th first connection wire  211  (shown as h in the figure) is located on a side of a first wire section  211 A of the i-th first connection wire  211  (shown as i in the figure) away from the first central axis a, and the m-th data line  100  (shown as m in the figure) is located on a side of the n-th data line  100  (shown as n in the figure) away from the first central axis a. 
     The second connection wire group  220  includes a j-th second connection wire  221  (shown as j in the figure) and a k-th second connection wire  221  (shown as k in the figure), the data lines  100  include an x-th data line  100  (shown as x in the figure) and a y-th data line  100  (shown as y in the figure), and the x-th data line  100  (shown as x in the figure) and the y-th data line  100  (shown as y in the figure) are located on the same side of the first central axis a, where j≠k and j and k are each a positive integer, and x≠y and x and y are each a positive integer. The j-th second connection wire  221  (shown as j in the figure) is electrically connected to the x-th data line  100  (shown as x in the figure), and the k-th second connection wire  221  (shown as k in the figure) is electrically connected to the y-th data line  100  (shown as y in the figure). A third wire section  221 A of the j-th second connection wire  221  (shown as j in the figure) is located on a side of a third wire section  221 A of the k-th second connection wire  221  (shown as k in the figure) away from the first central axis a, and the x-th data line  100  (shown as x in the figure) is located on a side of the y-th data line  100  (shown as y in the figure) away from the first central axis a. 
     The first connection wire group  210  includes multiple first connection wires  211 . As shown in  FIG.  4   , an example is illustrated where the first connection wire group  210  includes the h-th first connection wire  211  (shown as h in the figure) and the i-th first connection wire  211  (shown as i in the figure). The first wire section  211 A of the h-th first connection wire  211  is closer to the first central axis a than the first wire section  211 A of the i-th first connection wire  211 , while the m-th data line  100  (shown as m in the figure) electrically connected to the h-th first connection wire  211  is further away from the first central axis a than the n-th data line  100  (shown as n in the figure) electrically connected to the i-th first connection wire  211 . In other words, in the first connection wire group  210 , along the extension direction X 1  of the data line  100 , a first connection wire  211  whose extension length of the first wire section  211 A of the first connection wire  211  is relatively long has a relatively short transverse extension length, that is, the second wire section  211 B is relatively short; a first connection wire  211  whose extension length of the first wire section  211 A of the first connection wire  211  is relatively short has a relatively long transverse extension length, that is, the second wire section  211 B is relatively long. 
     Further, the wire extension trend of the second connection wires  221  in the second connection wire group  220  is the same as the wire extension trend of the first connection wire  211  in the first connection wire group  210 , which is not repeated. Moreover, as shown in  FIG.  4   , when the second wire section  211 B and the fourth wire section  221 B are located between adjacent two rows of subpixels  400 , the preceding position arrangement relationship can be satisfied. At the same time, referring to  FIG.  5   , the second wire section  211 B overlaps subpixels  400  along the thickness direction (not shown in the figure) of the display panel  10 , and the fourth wire section  221 B overlaps subpixels  400  along the thickness direction (not shown in the figure) of the display panel  10 , which are not repeated. In summary, first connection wires  211  and second connection wires  221  at different positions are disposed to be electrically connected to data lines  100  at different positions, so that for the first connection wire group  210  and the second connection wire group  220 , a connection wire whose extension length along the extension direction X 1  of the data lines  100  is relative long has a relatively short transverse extension length, that is, has a relatively short second wire section  211 B and a relatively short fourth wire section  221 B; and the connection wire whose extension length along the extension direction X 1  of the data lines  100  is relative short has a relatively long transverse extension length, that is, has a relatively long second wire section  211 B and a relatively long fourth wire section  221 B. In this manner, an adjustment is performed on lengths in different directions of the connection wires  200 , so that the loss of data signals on different connection wires  200  is adjusted, and the balance and stability of data signal transmission are ensured. 
       FIG.  9    is another enlarged diagram of the region for disposing the connection wires in  FIG.  1   . Referring to  FIG.  9   , the display panel  10  further includes power supply signal lines  500  located in the display region  110 , where the extension direction of the power supply signal lines  500  is parallel to the extension direction of the second wire section  211 B. A power supply signal line  500  includes a first power supply signal line  510  and a second power supply signal line  520  which are disposed adjacent to each other in the extension direction X 1  of the data lines  100 . The first power supply signal line  510  includes a first power supply section  510 A and a second power supply section  510 B which are connected to each other, the first power supply section  510 A is located between adjacent two second wire sections  211 B, along the thickness direction of the display panel  10 , the second power supply section  510 B and a fourth wire section  221 B overlap the same row of subpixels  400 , and the line width of the first power supply section  510 A is greater than the line width of the second power supply section  510 B; and/or the second power supply signal line  520  includes a third power supply section  520 A and a fourth power supply section  520 B which are connected to each other, the third power supply section  520 A is located between adjacent two fourth wire sections  221 B, along the thickness direction of the display panel  10 , the fourth power supply section  520 B and a second wire section  211 B overlap the same row of subpixels  400 , and the line width of the third power supply section  520 A is greater than the line width of the fourth power supply section  520 B. 
     The display panel  10  further includes multiple power supply signal lines  500 . The power supply signal lines  500  are disposed to achieve the transmission of power supply signals to the subpixels  400 , so that the display and light emission of the subpixels  400  are ensured, and thereby the display effect of the display panel  10  is ensured. The extension direction of the power supply signal lines  500  is parallel to the extension direction of the second wire section  211 B and the extension direction of the fourth wire section  221 B, and a power supply signal line  500  includes a first power supply signal line  510  and a second power supply signal line  520  which are disposed adjacent to each other in the extension direction X 1  of the data lines  100 , that is, power supply signals can be provided for different rows of subpixels  400 . 
     Further, when the connection wires  200  and the power supply signal lines  500  are all disposed in the display region  110 , to prevent signal coupling and crosstalk from being generated by the connection wires  200  and the power supply signal lines  500  during signal transmission and thereby affecting the transmission of signals in the display panel  10 , the first connection wire group  210  and the second connection wire group  220  are designed asymmetrically about the first central axis a, that is, it is ensured that the first connection wire group  210  and the second connection wire group  220  balance and reduce signal coupling and crosstalk generated by the power supply signal lines  500 , so that the signal transmission of the display panel  10  is ensured. 
     Further, referring to  FIG.  9   , a power supply signal line  500  includes a first power supply signal line  510  and a second power supply signal line  520  which are disposed adjacent to each other in the extension direction X 1  of the data lines  100 . The first power supply signal line  510  includes a first power supply section  510 A and a second power supply section  510 B which are connected to each other. The first power supply section  510 A is located between adjacent two second wire sections  211 B, and the distance between the first power supply section  510 A and the adjacent two second wire sections  211 B is relatively large; the second power supply section  510 B and a fourth wire section  221 B overlap the same row of subpixels  400 , that is, the distance between the second power supply section  510 B and the adjacent fourth wire section  221 B is relatively small. In this manner, in a case of reducing signal coupling and crosstalk generated by the power supply signal wires  500  and the connection wires  200 , the line width of the first power supply section  510 A is set to be greater than the line width of the second power supply section  510 B, thereby reducing the loss of power supply signals during transmission on the first power supply section  510 A, reducing the overall loss of signals during transmission on the power supply signal lines  500 , and ensuring the stability of signal transmission of the display panel  10 . 
     The second power supply signal line  520  includes a third power supply section  520 A and a fourth power supply section  520 B which are connected to each other. The third power supply section  520 A is located between adjacent two fourth wire sections  221 B, and the distance between the third power supply section  520 A and the adjacent two fourth wire sections  221 B is relatively large; the fourth power supply section  520 B and a second wire section  211 B overlap the same row of subpixels  400 , that is, the distance between the fourth power supply section  520 B and the adjacent second wire section  211 B is relatively small. In this manner, in the case of reducing signal coupling and crosstalk generated by the power supply signal wires  500  and the connection wires  200 , the line width of the third power supply section  520 A is set to be greater than the line width of the fourth power supply section  520 B, thereby reducing the loss of power supply signals during transmission on the third power supply section  520 A, reducing the overall loss of signals during transmission on the power supply signal lines  500 , and ensuring the stability of signal transmission of the display panel  10 . 
     With continued reference to  FIG.  9   , the power supply signal lines  500  include positive power supply signal lines and/or negative power supply signal lines.

     It is to be noted that the power supply signal lines  500  include positive power supply signal lines and negative power supply signal lines, representing that part of the virtual wires are connected to the positive power supply signal lines and part of the virtual wires are connected to the negative power supply signal line, rather than that the same virtual wire is connected to both a positive power supply signal line and a negative power supply signal line. 
       FIG.  10    is a diagram illustrating the structure of another display panel according to an embodiment of the present disclosure, and  FIG.  11    is an enlarged diagram of a region for disposing connection wires in  FIG.  10   . Referring to  FIG.  2   ,  FIG.  10    and  FIG.  11   , a first connection wire  211  includes a first wire section  211 A and a second wire section  211 B, where the first wire section  211 A and the second wire section  211 B are connected to each other, and the extension direction of the first wire section  211 A intersects the extension direction of the second wire section  211 B. A second connection wire  221  includes a third wire section  221 A and a fourth wire section  221 B, where the third wire section  221 A and the fourth wire section  221 B are connected to each other, and the extension direction of the third wire section  221 A intersects the extension direction of the fourth wire section  221 B. The display panel further includes multiple subpixels  400  located in the display region  110 , and the multiple subpixels  400  are arranged in an array. Along the thickness direction of the display panel  10 , the extension length of a second wire section  211 B overlapping a row of subpixels  400  is different from the extension length of a fourth wire section  221 B overlapping the row of subpixels  400 . 
     A first connection wire  211  includes a first wire section  211 A and a second wire section  211 B, and a second connection wire  221  includes a third wire section  221 A and a fourth wire section  221 B. Wire sections which are connected to each other and whose extension directions intersect are set, so that electrical connection in the display panel  10  between the data lines  100  in the display region  110  and the signal wires  300  in the non-display region  120  is achieved through the connection wires  200 , various arrangements of the connection wires  200  are achieved through the adjustment on different wire sections, and the diversity of the display panel  10  is improved. 
     Further, the display region  110  includes multiple array subpixels  400 , and the subpixels  400  are driven to emit light, so as to achieve the display function of the display panel  10 . The subpixels  400  include red subpixels, green subpixels and blue subpixels, and the color and type of the subpixels  400  are not specifically limited in the embodiment of the present disclosure. 
     Further, referring to  FIG.  2   ,  FIG.  10    and  FIG.  11   , along the thickness direction of the display panel  10 , the extension length of a second wire section  211 B overlapping a row of subpixels  400  is different from the extension length of a fourth wire section  221 B overlapping the row of subpixels  400 , so that the first connection wire group  210  and the second connection wire group  220  are disposed asymmetrically about the first central axis a.

The first connection wire group  210  and the second connection wire group  220  are disposed asymmetrically, so that crosstalk of signal lines existing in the display panel  10  is balanced, and the display balance of the display panel  10  is improved. 
     With continued reference to  FIG.  9   ,  FIG.  10    and  FIG.  11   , along the direction X 2  from which the display region  110  points to the non-display region  120 , extension lengths of second wire sections  211 B gradually decrease, and extension lengths of fourth wire sections  221 B gradually increase. 
     As shown in  FIG.  6   , the display panel  10  further includes a power supply signal bus  500 A located in the non-display region  120  and power supply signal lines  500  connected to the power supply signal bus  500 A, and power supply signals flow from the non-display region  120  to the display region  110 . Since line resistance exists in the power supply signal lines  500 , to ensure the overall signal transmission effect of the display panel  10 , that is, to reduce overall crosstalk, the extension lengths of the second wire sections  211 B of the first connection wires  211  are adjusted. 
     In an embodiment, along the direction X 2  from which the display region  110  points to the non-display region  120 , the extension lengths of the second wire sections  211 B gradually decrease, that is, extension lengths of positions where coupling crosstalk is likely to generate in the display panel  10  are reduced, so that the transmission stability and balance of signals in the wires in the display panel  10  are improved In a case where along the thickness direction of the display panel  10 , the extension length of a second wire section  211 B overlapping a row of subpixels  400  is different from the extension length of a fourth wire section  221 B overlapping the row of subpixels  400 , the extension lengths of the second wire sections  211 B along the direction X 2  from which the display region  110  points to the non-display region  120  is in a decreasing trend, and then the extension lengths of the fourth wire sections  221 B along the direction X 2  from which the display region  110  points to the non-display region  120  may be in an increasing trend, so as to ensure the arrangement that the first connection wire group  210  and the second connection wire group  220  are asymmetrical about the first central axis a. 
     With continued reference to  FIG.  10    and  FIG.  11   , the first connection wire group  210  includes a p-th first connection wire  211  (shown as p in the figure), and the second connection wire group  220  includes a q-th second connection wire  221  (shown as q in the figure). A straight line where a first wire section  211 A of the p-th first connection wire  221  (shown as p in the figure) is located and a straight line where a third wire section  221 A of the q-th second connection wire  221  (shown as q in the figure) is located are symmetrical about the first central axis a. The extension length of a second wire section  211 B of the p-th first connection wire  221  (shown as p in the figure) is the same as the extension length of a fourth wire section  221 B of the q-th second connection wire  221  (shown as q in the figure). 
     In an embodiment, referring to  FIG.  11   , the first connection wire group  210  includes the p-th first connection wire  211  (shown as p in the figure), and the second connection wire group  220  includes the q-th second connection wire  221  (shown as q in the figure). The value of p and the value of q are not specifically limited in the embodiment of the present disclosure. In a case where along the direction X 2  from which the display region  110  points to the non-display region  120 , the extension lengths of the second wire sections  211 B gradually decrease and the extension lengths of the fourth wire sections  221 B gradually increase, and the straight line where the first wire section  211 A of the p-th first connection wire  211  (shown as p in the figure) is located and the straight line where the third wire section  221 A of the q-th second connection wire  221  (shown as q in the figure) is located are symmetrical about the first central axis a, the extension length of the second wire section  211 B is the same as the extension length of the fourth wire section  221 B. That is, in the first connection wire group  210  and the second connection wire group  220 , when the first wire section  211 A of the first connection wire  211  and the third wire section  221 A of the second connection wire  221  are symmetrical about the first central axial a, and the extension length of the second wire section  211 B of the first connection wire  211  is same as the extension length of the fourth wire section  221 B of the second connection wire  221 , the extension length of the first wire section  211 A of the first connection wire  211  and the extension length of the third wire section  221 A of the second connection wire  221  may be adjusted, so as to achieve the asymmetrical arrangement of the first connection wire group  210  and the second connection wire group  220 , and ensure the display effect of the display panel. 
       FIG.  12    is another enlarged diagram of the region for disposing the connection wires in  FIG.  1   . Referring to  FIG.  2   ,  FIG.  6    and  FIG.  12   , along the direction X 2  from which the display region  110  points to the non-display region  120 , extension lengths of second wire connections  211 B gradually decrease. The second connection wire group  220  includes a b-th second connection wire  221  (shown as b in the figure) and a c-th second connection wire  221  (shown as c in the figure), the data lines  100  include a d-th data line  100  (shown as d in the figure) and an e-th data line  100  (shown as e in the figure), and the d-th data line  100  (shown as d in the figure) and the e-th data line  100  (shown as e in the figure) are located on the same side of the first central axis a, where b≠c and b and c are each a positive integer, and d≠e and d and e are each a positive integer. The b-th second connection wire  221  (shown as b in the figure) is electrically connected to the d-th data line  100  (shown as d in the figure), and the c-th second connection wire  221  (shown as c in the figure) is electrically connected to the e-th data line  100  (shown as e in the figure). A third wire section  221 A of the b-th second connection wire  221  (shown as b in the figure) is located on a side of a third wire section  221 B of the c-th second connection wire (shown as c in the figure) away from the first central axis a, and the d-th data line  100  (shown as d in the figure) is located on a side of the e-th data line  100  (shown as e in the figure) away from the first central axis a. 
     As shown in  FIG.  6   , the display panel  10  further includes a power supply signal bus  500 A located in the non-display region  120  and power supply signal lines  500  connected to the power supply signal bus  500 A, and power supply signals flow from the non-display region  120  to the display region  110 . Since line resistance exists in the power supply signal lines  500 , to ensure the overall signal transmission effect of the display panel  10 , that is, to reduce overall crosstalk, the extension lengths of the second wire sections  211 B of the first connection wires  211  are adjusted. 
     In an embodiment, along the direction X 2  from which the display region  110  points to the non-display region  120 , the extension lengths of the second wire sections  211 B gradually decrease, that is, extension lengths of positions where coupling crosstalk is likely to generate in the display panel  10  are reduced, so that the transmission stability and balance of signals in the wires in the display panel  10  are improved 
     Further, the first connection wire group  210  includes multiple first connection wires  211 . As shown in  FIG.  12   , the b-th second connection wire  221  (shown as b in the figure) and the c-th second connection wire  221  (shown as c in the figure) are taken as an example for illustration. 
     In an embodiment, the third wire section  221 A of the b-th second connection wire  221  (shown as b in the figure) is further away from the first central axis a than the third wire section  221 A of the c-th second connection wire  221  (shown as c in the figure), while the d-th data line  100  (shown as d in the figure) electrically connected to the b-th second connection wire  221  (shown b in the figure) is further away from the first central axis a than the e-th data line  100  (shown as e in the figure) electrically connected to the c-th second connection wire  221  (shown as c in the figure). In other words, when the extension lengths of the second wire sections  211 B gradually decrease along the direction X 2  from which the display region  110  points to the non-display region  120 , in the second connection wire group  220 , along the extension direction X 1  of the data lines  100 , a second connection wire  221  whose extension length of the third wire section  221 A of the second connection wire  221  is relatively long has a relatively short transverse extension length, while a second connection wire  221  whose extension length of the third wire section  221 A of the second connection wire  221  is relatively short has a relatively long transverse extension length. In this manner, the loss of data signals from the data lines  100  on different connection wires  200  is adjusted, and the balance and stability of data signal transmission are ensured. 
       FIG.  13    is a diagram illustrating the structure of another display panel according to an embodiment of the present disclosure, and  FIG.  14    is an enlarged diagram of a region for disposing connection wires in  FIG.  13   .

The connection wires  200  include an f-th connection wire  200  (shown as f in the figure) and a g-th connection wire  200  (shown as g in the figure), the f-th connection wire  200  (shown as fin the figure) is located in the first connection wire group  210  or the second connection wire group  220 , and the g-th connection wire  200  (shown as g in the figure) is located in the first connection wire group  210  or the second connection wire group  220 . The f-th connection wire  200  (shown as fin the figure) includes an f-th subsection f 1  and an f-th sub-wire f 2 , and the g-th connection wire  200  (shown as g in the figure) includes a g-th subsection g 1  and a g-th sub-wire g 2 , where the f-th subsection f 1  is a first wire section  211 A or a third wire section  221 A, the f-th sub-wire f 2  is a second wire section  211 B or a fourth wire section  221 B, the g-th subsection g 1  is a first wire section  211 A or a third wire section  221 A, and the g-th sub-wire g 2  is a second wire section  211 B or a fourth wire section  221 B. The length of the f-th subsection f 1 , the length of the f-th sub-wire f 2 , the length of the g-th subsection g 1  and the length the g-th sub-wire g 2  are respectively L 11 , L 12 , L 21  and L 22 , where (L 11 −L 21 )×(L 12 −L 22 )≤0. 
     In an embodiment, a first connection wire  211  includes a first wire section  211 A and a second wire section  211 B, and a second connection wire  221  includes a third wire section  221 A and a fourth wire section  221 B. Wire sections which are connected to each other and whose extension directions intersect are set, so that electrical connection in the display panel  10  between the data lines  100  in the display region  110  and the signal wires  300  in the non-display region  120  is achieved through the connection wires  200 , various arrangements of the connection wires  200  are achieved through the adjustment on different wire sections, and the diversity of the display panel  10  is improved. 
     In an embodiment, the connection wires  200  include the f-th connection wire  200  (shown as fin the figure) and the g-th connection wire  200  (shown as g in the figure), and the f-th connection wire  200  (shown as f in the figure) and the g-th connection wire  200  (shown as g in the figure) may both be first connection wires  211  or may both be second connection wires  221 ; or one of the f-th connection wire  200  and the g-th connection wire  200  is a first connection wire  211  and the other of the f-th connection wire  200  and the g-th connection wire  200  is a second connection wire  221 , which is not specifically limited in the embodiment of the present disclosure. Referring to  FIG.  13    and  FIG.  14   , an example is illustrated where the f-th connection wire  200  (shown as fin the figure) and the g-th connection wire  200  (shown as g in the figure) are second connection wires  221 . 
     In an embodiment, referring to  FIG.  13    and  FIG.  14   , the f-th connection wire  200  (shown as fin the figure) includes the f-th subsection f 1  and the f-th sub-wire f 2 , and the g-th connection wire  200  (shown as g in the figure) includes the g-th subsection g 1  and the g-th sub-wire g 2 . The f-th subsection f 1  and the g-th subsection g 1  are third wire sections  221 A of different second connection wires  221 , respectively, and the f-th sub-wire f 2  and the g-th sub-wire g 2  are fourth wire sections  221 B of different second connection wires  221 , respectively. 
     In an embodiment, with continued reference to  FIG.  13    and  FIG.  14   , the length of the f-th subsection f 1  is L 11 , the length of the g-th subsection g 1  is L 21 , and the length L 11  of the f-th subsection f 1  is less than the length L 21  of the g-th subsection g 1 . At the same time, the length of the f-th sub-wire f 2  is L 12 , the length of the g-th sub-wire g 2  is L 22 , and the length L 12  of the f-th sub-wire f 2  is greater than the length L 22  of the g-th sub-wire g 2 . That is, when L 11  is less than L 21 , L 12  is greater than L 22 , so as to satisfy that (L 11 −L 21 )×(L 12 −L 22 )≤0. Similarly, when the length L 11  of the f-th subsection f 1  is greater than the length L 21  of the g-th subsection g 1 , the length L 12  of the f-th sub-wire f 2  is less than the length L 22  of the g-th sub-wire g 2 ; that is, when L 11  is greater than L 21  (not shown in the figure), L 12  is less than L 22 , and it is also satisfied that (L 11 −L 21 )×(L 12 −L 22 )≤0. Only one case is illustrated in the figure, which is not specifically limited in the embodiment of the present disclosure. 
     When it is ensured that the first connection wire group  210  and the second connection wire group  220  are disposed asymmetrically about the first central axis a, crosstalk of signal transmission in the display panel  10  can be balanced or reduced. Extension lengths of different connection wires  200  in different directions are adjusted, that is, when the extension lengths of the connection wires  200  along the extension direction X 1  of the data lines  100  are relatively short, the extension lengths of the connection wires  200  perpendicular to the extension direction X 1  of the data lines may be increased, so as to avoid different degrees of loss of signals during transmission caused by large differences in resistance of the connection wires  200  at different positions, that is, to further ensure the signal transmission balance of the display panel  10 , and improve the display effect of the display panel  10 . 
       FIG.  15    is another enlarged diagram of the region for disposing the connection wires in  FIG.  1   . Referring to  FIG.  1    and  FIG.  15   , a first connection wire  211  includes a first wire section  211 A and a second wire section  211 B, where the first wire section  211 A and the second wire section  211 B are connected to each other, and the extension direction of the first wire section  211 A intersects the extension direction of the second wire section  211 B. A second connection wire  221  includes a third wire section  221 A and a fourth wire section  221 B, where the third wire section  221 A and the fourth wire section  221 B are connected to each other, and the extension direction of the third wire section  221 A intersects the extension direction of the fourth wire section  221 B. The first wire section  211 A and the third wire section  221 A are both disposed in the same layer as the data lines  100  and are parallel to the extension direction of the data lines  100 , and the extension direction of the second wire section  211 B and the extension direction of the fourth wire section  221 B both intersect the extension direction of the data lines  100 . The width of the second wire section  211 B is greater than the width of the first wire section  211 A, and the width of the fourth wire section  221 B is greater than the width of the third wire section  221 A. 
     A first connection wire  211  includes a first wire section  211 A and a second wire section  211 B, and a second connection wire  221  includes a third wire section  221 A and a fourth wire section  221 B. The first wire section  211 A and the third wire section  221 A are disposed in the same layer and are parallel to the extension direction of the data lines  100 , that is, the first wire section  211 A and the third wire section  221 A each have a relatively large contact area with the data lines  100 ; the extension direction of the second wire section  211 B and the extension direction of the fourth wire section  221 B both intersect the extension direction of the data lines  100 , that is, the second wire section  211 B and the fourth wire section  221 B each have a relatively small contact area with the data lines  100 . When signal transmission is performed in the display panel  10 , crosstalk is more likely generated between the first wire section  211 A as well as the third wire section  221 A and the data lines  100  than between the second wire section  211 B as well as the fourth wire section  221 B and the data lines  100 ; therefore, the wire width of the first wire section  211 A and the wide width of the third wire section  221 A are set to be less than the wire width of the second wire section  211 B and the wire width of the fourth wire section  221 B, so as to reduce crosstalk generated along the extension direction X 1  of the data lines  100  in the display panel  10 , and ensure the stability of signal transmission of the display panel  10 . Further, the first connection wire group  210  and the second connection wire group  220  are designed asymmetrically about the first central axis a, so that crosstalk generated along the direction perpendicular to the extension direction of the data lines  100  can be effectively reduced, and thus the stability of signal transmission in the display panel  10  is ensured. 
       FIG.  16    is a diagram illustrating the structure of another display panel according to an embodiment of the present disclosure. Referring to  FIG.  16   , a first connection wire  211  includes a first wire section  211 A and a second wire section  211 B, where the first wire section  211 A and the second wire section  211 B are connected to each other, and the extension direction of the first wire section  211 A intersects the extension direction of the second wire section  211 B. A second connection wire  221  includes a third wire section  221 A and a fourth wire section  221 B, where the third wire section  221 A and the fourth wire section  221 B are connected to each other, and the extension direction of the third wire section  221 A intersects the extension direction of the fourth wire section  221 B. The included angle between the first wire section  211 A and the second wire section  211 B is a first included angle n 1 , and the included angle between the third wire section  221 A and the fourth wire section  221 B is a second included angle n 2 , where the first included angle n 1  is less than the second included angle n 2 . 
     A first connection wire  211  includes a first wire section  211 A and a second wire section  211 B, a second connection wire  221  includes a third wire section  221 A and a fourth wire section  221 B, and the first included angle n 1  exists between the first wire section  211 A and the second wire section  211 B, and the second included angle n 2  exists between the third wire section  221 A and the fourth wire section  221 B. Referring to  FIG.  16   , the first included angle n 1  is different from the second included angle n 2 , that is, the connection inclination of the first wire section  211 A and the second wire section  211 B of the first connection wire  211  is different from the connection inclination of the third wire section  221 A and the fourth wire section  221 B of the second connection wire  221 , therefore, the asymmetrical design of the first connection wire group  210  and the second connection wire group  220  about the first central axis a is achieved, so that the stability of signal transmission of the display panel  10  is ensured. 
     With continued reference to  FIG.  4    and  FIG.  5   , a first connection wire  211  includes a first wire section  211 A and a second wire section  211 B, where the first wire section  211 A and the second wire section  211 B are connected to each other, and the extension direction of the first wire section  211 A intersects the extension direction of the second wire section  211 B. A second connection wire  221  includes a third wire section  221 A and a fourth wire section  221 B, where the third wire section  221 A and the fourth wire section  221 B are connected to each other, and the extension direction of the third wire section  221 A intersects the extension direction of the fourth wire section  221 B. The display panel  10  further includes multiple subpixels  400  located in the display region  110 , and the multiple subpixels  400  are arranged in an array. At least a row of subpixels  400  are disposed between adjacent two first wire sections  211 A, and at least a row of subpixels  400  are disposed between adjacent two third wire sections  221 A. 
     A first connection wire  211  includes a first wire section  211 A and a second wire section  211 B, and a second connection wire  221  includes a third wire section  221 A and a fourth wire section  221 B. Various arrangements of the connection wires  200  are achieved through the adjustment on different wire sections, and thus the diversity of the display panel  10  is improved. At the same time, the display region  110  includes multiple array subpixels  400 , and the subpixels  400  are driven to emit light, so as to achieve the display function of the display panel  10 . The subpixels  400  include red subpixels, green subpixels and blue subpixels, and the color and type of the subpixels  400  are not specifically limited in the embodiment of the present disclosure. 
     Further, referring to  FIG.  4    and  FIG.  5   , in the first connection wire group  210 , at least a row of subpixels  400  are disposed between adjacent two first wire sections  211 A. The figure only illustrate an example where a row of subpixels  400  are disposed between adjacent two first wire sections  211 A. In this manner, it is avoided that different first connection wires  211  are arranged too closely, and thus the generation of signal crosstalk in the display panel  10  is further reduced. The same manner is applied to the arrangement of adjacent third wire sections  221 A in the second connection wire group  220 , which is not repeated here. 
       FIG.  17    is a sectional diagram taken along direction D-D′ of  FIG.  9   . Referring to  FIG.  9    and  FIG.  17   , a first connection wire  211  includes a first wire section  211 A and a second wire section  211 B, where the first wire section  211 A and the second wire section  211 B are connected to each other, and the extension direction of the first wire section  211 A intersects the extension direction of the second wire section  211 B. A second connection wire  221  includes a third wire section  221 A and a fourth wire section  221 B, where the third wire section  221 A and the fourth wire section  221 B are connected to each other, and the extension direction of the third wire section  221 A intersects the extension direction of the fourth wire section  221 B. The display panel  10  further includes power supply signal lines  500  located in the display region  110 , and the extension direction of the power supply signal lines  500  is parallel to the extension direction of the second wire section  211 B. 
     The first wire section  211 A and the second wire section  211 B are disposed in different layers, and the third wire section  221 A and the fourth wire section  221 B are disposed in different layers. The first wire section  211 A, the third wire section  221 A and the data lines  100  are disposed in the same layer, and the second wire section  211 B, the fourth wire section  221 B and the power supply signal lines  500  are disposed in the same layer. 
     In the sectional diagram of the display region  110  of the display panel  10 , the display panel  10  includes an array layer  130  and includes pixel drive circuits  131  in the array layer  130 , and subpixels are driven by the pixel drive circuits  130  to display and emit light. A pixel drive circuit  131  includes an active layer, a gate, a capacitor layer, a source and a drain and the like which are disposed in a laminated manner, and those skilled in the art may adjust the film layers adaptively according to actual requirements. 
     Further, the first wire section  211 A, the third wire section  221 A and the data lines  100  may be disposed in the same layer, and the second wire section  211 B, the fourth wire section  221 B and power supply signal lines  500  may be disposed in the same layer. On this basis, the first wire section  211 A and the second wire section  211 B need to be disposed in different layers, and the third wire section  221 A and the fourth wire section  221 B need to be disposed in different layers. In this manner, multiple wires are disposed in the same layer, so that the thickness of the display panel  10  can be reduced, and the thin design of the display panel  10  can be achieved.
