[0025] The present application will be further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are intended to be merely illustrative of the present application and not in limitation thereof. It should also be noted that, for the purpose of description, only the parts related to the present application are shown in the drawings rather than all the parts.

[0026] Figure 1 is a structure diagram of a display panel according to an embodiment of the present application. As shown in Figure 1 , the present application provides a display panel 10, which includes a display area 110 and a non-display area 120, the non-display area 120 being located at least at one side of the display area 110; the display area 110 includes a plurality of data lines 100, and the non-display area 120 includes a plurality of pads 200; the data lines 100 extend along a first direction X, and the plurality of data lines 100 are arranged along a second direction Y, the first direction X and the second direction Y being intersected; the display panel 10 further includes connection traces 300, the connection traces 300 being electrically connected with the pads 200 and the data lines 100 respectively; the connection traces 300 include first trace parts 310 and second trace parts 320 which are disposed in different layers and connected with each other, and the extending direction of the first trace parts 310 intersects with the extending direction of the second trace parts 320.

[0027] Specifically, the display panel 10 includes the display area 110 and the non-display area 120, the display area 110 includes sub-pixels (not specifically shown in the drawings) and display signal lines such as the data lines 100 connected with the sub-pixels, for realizing the display function of the display panel 10. The non-display area 120 includes a plurality of pads 200 connected with the display signal lines, and the display panel 10 provides display signals to the data lines 100 through the pads 200, thereby driving the display panel 10 to realize the display function. Exemplarily, as shown in Figure 1 , the non-display area 120 can be a lower frame area located at one side of the display area 110. The present application does not specifically limit the positional relationship between the display area 110 and the non-display area 120.

[0028] Further, as shown in Figure 1As shown, the display panel 10 further comprises a connection trace 300, through which the data line 100 located in the display area 110 and the pad 200 located in the non-display area 120 are electrically connected, ensuring signal transmission, and thus realizing the display function of the display panel 10. Specifically, referring to Figure 1 As shown, the connection trace 300 extends to the display area 110 of the display panel 10 to ensure the electrical connection of the data line 100 and the pad 200, which can reduce the area of the non-display area 120 of the display panel 10, i.e. improve the proportion of the display area 110 in the display panel 10. The connection trace 300 is arranged in the display area 110, which effectively ensures the narrow frame effect of the display panel 10.

[0029] Further, the connection trace 300 comprises a first trace part 310 and a second trace part 320, i.e. the data line 100 is connected to the pad 200 through the first trace part 310 and the second trace part 320 intersecting in the extension direction. If the first trace part 310 and the second trace part 320 are arranged in the same layer, a connection inflection point needs to be arranged to ensure the connection of the first trace part 310 and the second trace part 320, but the existence of multiple connection inflection points will affect the display effect of the display panel 10. Therefore, the first trace part 310 and the second trace part 320 are arranged in different layers in the embodiment of the present application, and the first trace part 310 and the second trace part 320 arranged in different layers can be connected through a punching process, without the need for a connection inflection point to connect them, i.e. fundamentally solving the problem of affecting the display uniformity of the display panel 10 to ensure the connection of the first trace part 310 and the second trace part 320, and thus improving the display effect of the display panel 10.

[0030] In summary, the display panel provided by the embodiment of the present application, wherein the connection trace of the display panel comprises a first trace part and a second trace part, and the extension direction of the first trace part intersects with the extension direction of the second trace part, and the first trace part and the second trace part are arranged in different layers and connected to each other. In the display panel, the first trace part and the second trace part of the connection trace are arranged in different layers, avoiding the influence of the connection inflection point existing when the first trace part and the second trace part are arranged in the same layer on the display uniformity of the display panel, i.e. the display panel provided by the embodiment avoids the appearance of the connection inflection point, thereby improving the display effect of the display panel.

[0031] Continuing to refer to Figure 1 As shown, the display panel 10 further comprises a first central axis a covering the center A of the display panel 10 and extending along the second direction Y; among the plurality of second trace parts 320, part of the second trace parts 320 are located on the side of the first central axis a away from the non-display area 120, and part of the second trace parts 320 are located on the side of the first central axis a close to the non-display area 120.

[0032] The display panel 10 includes a first central axis a, as shown by reference Figure 1 The time delay direction of the first central axis a is the same as the second direction Y, and the first central axis a covers the center A of the display panel 10, that is, the display panel 10 on both sides of the first central axis a has the same or similar area size. Further, part of the second wire distribution 320 is located on the side of the first central axis a away from the non-display area 120, and part of the second wire distribution 320 is located on the side of the first central axis a close to the non-display area 120, that is, the second wire distribution 320 is distributed in the entire display area 110 of the display panel 10, so that the distribution of the wires in the display panel 10 can be evenly displayed, the density difference of the second wire distribution 320 in the display panel 10 is reduced, the display effect of the display panel 10 caused by the density difference of the wires is weakened, and the display effect of the display panel 10 is ensured. Further, the second wire distribution 320 is distributed in the entire display area 110 of the display panel 10, which can increase the distance between two adjacent second wire distributions 320 in the first direction X, reduce the signal crosstalk between different second wire distributions 320, ensure the signal transmission effect, and further ensure the display effect of the display panel 10.

[0033] Figure 2 is another structural schematic diagram of a display panel provided by an embodiment of the present application, as shown by reference Figure 2 As shown, along the extension direction of the data line 100, a plurality of second wire distributions 320 are evenly arranged in the display area 110.

[0034] Among them, a plurality of second wire distributions 320 can be evenly arranged in the display area 110, that is, the distance between any two second wire distributions 320 is the same or approximately the same, as shown by reference Figure 2 Further reduce the density difference of the wire distribution in the display panel 10, and further reduce the signal crosstalk between different second wire distributions 320, etc., to ensure the display effect of the display panel 10 as a whole.

[0035] For example, the display panel 10 includes a plurality of sub-pixels (not specifically shown in the figure) arranged in rows and columns, that is, the first direction X and the second direction Y, which realize the display and light emission of the display panel 10. The second wire distribution 320 between adjacent second wire distributions 320 can include the same number of sub-pixels, for example, each second wire distribution 320 is separated by 5 rows of sub-pixels, and the present application does not make specific limitations on this.

[0036] Figure 3 is another structural schematic diagram of a display panel provided by an embodiment of the present application, Figure 4 is another structural schematic diagram of a display panel provided by an embodiment of the present application, Figure 5This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 6 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, for reference. Figures 3 to 6 As shown, the display panel 10 also includes a second central axis b, which covers the center A of the display panel 10 and extends along the first direction X; the display panel 10 includes 2M connecting traces 300; along the first direction X, 2M second trace portions 320 are arranged sequentially, and along the second direction Y, 2M first trace portions 310 are arranged sequentially; M≥1 and M is an integer; wherein, the first first trace portion 310 (m1 in the figure) to the Mth first trace portion 310 (m3 in the figure) Or M) in the figure is located on the same side of the second central axis b, the (M+1)th first routing section 310 (m4 in the figure or M+1 in the figure) to the 2Mth first routing section 310 (m6 in the figure) are located on the same side of the second central axis b; when i≤M, the ith first routing section 310 is electrically connected to the (2j-1)th second routing section 320; where i and j are both positive integers; when i>M, the ith first routing section 310 is electrically connected to the (2j)th second routing section 320.

[0037] The display panel 10 includes a second central axis b, as referenced. Figures 3 to 6 As shown, the extension direction of the second central axis a is the same as that of the first direction X, and the second central axis b covers the center A of the display panel 10, that is, the display panel 10 on both sides of the second central axis a has the same or similar area. Furthermore, the first wiring distribution 310 is evenly distributed on both sides of the second central axis b, which can reduce the density difference of the first wiring distribution 310 in the display panel 10, weaken the display effect caused by the difference in wiring density, and ensure the display effect of the display panel 10.

[0038] Further reference Figures 3 to 6 As shown, the display panel 10 includes 2M connecting traces 300. For example, M=3 is used in the figure for illustration, meaning the display panel 10 includes 6 connecting traces 300. This embodiment of the invention does not specifically limit the number of connecting traces. Specifically, the first first trace portion 310 (m1 in the figure) to the Mth first trace portion 310 (m3 or M in the figure) are located on the same side of the second central axis b, and the (M+1)th first trace portion 310 (m4 or M+1 in the figure) to the 2Mth first trace portion 310 (m6 in the figure) are also located on the same side of the second central axis b. That is, the 6 connecting traces 300 are evenly distributed on both sides of the second central axis b.

[0039] Further reference Figures 3 to 6As shown, the i-th first trace part 310 is electrically connected with the (2j-1)-th second trace part 320 when i≤M, and the i-th first trace part 310 is electrically connected with the (2j)-th second trace part 320 when i>M. For example, when M=3, the first three first trace parts 310 are respectively electrically connected with the odd-numbered second trace parts 320, and the fourth to sixth first trace parts 310 are respectively electrically connected with the even-numbered second trace parts 320. For reference Figure 3 As shown, the first first trace part 310 (m1 in the figure) is connected with the first second trace part 320 (s1 in the figure), and the fourth first trace part 310 (m4 in the figure) is connected with the fourth second trace part 320 (s4 in the figure). Various cases are not described one by one here. Such an arrangement can ensure that two first trace parts 310 arranged adjacent in the second direction Y are electrically connected with two second trace parts 320 not adjacent in the first direction X, or in other words, two second trace parts 320 arranged adjacent in the first direction X are electrically connected with two first trace parts 310 not adjacent in the second direction Y, so that the distance between different connection vias can be large. Moreover, the first trace parts 310 on different sides of the second central axis b are respectively electrically connected with odd-numbered second trace parts 320 and even-numbered second trace parts 320, which can also ensure that the connection vias of the first connection trace parts 310 and the second connection trace parts 320 are uniformly distributed in the entire display area. The connection vias with a large distance between adjacent two and uniform distribution can on the one hand ensure that the via process implementation is simple, and on the other hand ensure that the display effect of the display panel 10 as a whole is balanced.

[0040] Optionally, continuing to refer to Figure 3 As shown, j=i when i≤M, and j=i-M when i>M.

[0041] For reference Figure 3As shown, taking M=3 as an example, when i≤M, i.e. the first three connection traces 300, and the ith first trace part 310 is electrically connected with the (2j-1)th second trace part 320, and j=i at the same time, for example, when i=1, j=1, 2j-1=1, the first first connection trace part 310 (m1 in the figure) is electrically connected with the first second trace part 320 (s1 in the figure), when i=2, j=2, 2j-1=3, the second first connection trace part 310 (m2 in the figure) is electrically connected with the third second trace part 320 (s3 in the figure), and when i=3, j=3, 2j-1=5, the third first connection trace part 310 (m3 in the figure) is electrically connected with the fifth second trace part 320 (s5 in the figure). At the same time, when i>M, the ith first trace part 310 is electrically connected with the (2j)th second trace part 320, and j=i-M, for example, when i=4, j=i-M=1, 2j=2, the fourth first connection trace part 310 (m4 in the figure) is electrically connected with the second second trace part 320 (s2 in the figure), when i=5, j=i-M=2, 2j=4, the fifth first connection trace part 310 (m5 in the figure) is electrically connected with the fourth second trace part 320 (s4 in the figure), and when i=6, j=i-M=3, 2j=6, the sixth first connection trace part 310 (m6 in the figure) is electrically connected with the sixth second trace part 320 (s6 in the figure). By using the connection mode of the first trace part 310 and the second trace part 320 provided in the embodiment, the connection via holes can be arranged uniformly, and meanwhile, the connection via holes corresponding to any two adjacent second trace parts 320 in the second direction Y have a large spacing, i.e. the distribution density of the connection via holes is reduced, the process complexity of the connection via holes and the influence on display caused by the concentrated arrangement of the connection via holes are avoided, the process difficulty of the display panel 10 is reduced, and the display effect of the display panel 10 is improved

[0042] Optionally, continuing to refer to Figure 4 As shown, when i≤M, j=i; and when i>M, j=2M-i+1.

[0043] In the formula, refer to Figure 4As shown, taking M=3 as an example, when i≤M, i.e. the first three connection wires 300, and the ith first wire part 310 is electrically connected with the (2j-1)th second wire part 320, if j=i at the same time, for example, i=1, j=1, 2j-1=1, then the first first connection wire part 310 (m1 in the figure) is electrically connected with the first second wire part 320 (s1 in the figure), i=2, j=2, 2j-1=3, then the second first connection wire part 310 (m2 in the figure) is electrically connected with the third second wire part 320 (s3 in the figure), i=3, j=3, 2j-1=5, then the third first connection wire part 310 (m3 in the figure) is electrically connected with the fifth second wire part 320 (s5 in the figure). At the same time, when i>M, the ith first wire part 310 is electrically connected with the (2j)th second wire part 320, and j=2M-i+1, for example, i=4, j=2M-i+1=3, 2j=6, then the fourth first connection wire part 310 (m4 in the figure) is electrically connected with the sixth second wire part 320 (s6 in the figure), i=5, j=2M-i+1=2, 2j=4, then the fifth first connection wire part 310 (m5 in the figure) is electrically connected with the fourth second wire part 320 (s4 in the figure), i=6, j=2M-i+1=1, 2j=2, then the sixth first connection wire part 310 (m6 in the figure) is electrically connected with the second second wire part 320 (s2 in the figure). By using the connection mode of the first wire part 310 and the second wire part 320 provided in the embodiment, the maximum spacing of the connection vias corresponding to the adjacent two second wire parts 320 in the second direction Y can be ensured under the premise of ensuring balanced connection via arrangement, the distribution density of the connection vias is reduced to the maximum extent, the via process is simple to the maximum extent, and the display effect is good. Taking Figure 4 For example, in the region far from the non-display area side of the first central axis a, the connection vias corresponding to the adjacent two second wire parts 320 in the second direction Y all have a larger spacing, i.e. a region with a smaller via distribution density, which can be a fine display region or a region with higher requirements for display uniformity, so that the fine display requirement or balanced display region can be ensured, and the multifunctionality or personalized display requirement of the display panel 10 can be ensured.

[0044] Optionally, as shown in Figure 5 When i≤M, j=M-i+1; when i>M, j=i-M.

[0045] Wherein, as shown in Figure 5As shown, taking M=3 as an example, when i≤M, i.e. the first three connection wires 300, and the ith first wire part 310 is electrically connected with the (2j-1)th second wire part 320, and j=M-i+1, for example, when i=1, j=M-i+1=3, 2j-1=5, the first first connection wire part 310 (m1 in the figure) is electrically connected with the fifth second wire part 320 (s5 in the figure), when i=2, j=M-i+1=2, 2j-1=3, the second first connection wire part 310 (m2 in the figure) is electrically connected with the third second wire part 320 (s3 in the figure), and when i=3, j=M-i+1=1, 2j-1=1, the third first connection wire part 310 (m3 in the figure) is electrically connected with the first second wire part 320 (s1 in the figure).

[0046] Meanwhile, when i>M, the ith first wire part 310 is electrically connected with the (2j)th second wire part 320, and j=i-M, for example, when i=4, j=i-M=1, 2j=2, the fourth first connection wire part 310 (m4 in the figure) is electrically connected with the second second wire part 320 (s2 in the figure), when i=5, j=i-M=2, 2j=4, the fifth first connection wire part 310 (m5 in the figure) is electrically connected with the fourth second wire part 320 (s4 in the figure), and when i=6, j=i-M=3, 2j=6, the sixth first connection wire part 310 (m6 in the figure) is electrically connected with the sixth second wire part 320 (s6 in the figure). The connection mode of the first wire part 310 and the second wire part 320 provided by the embodiment can further ensure that the connection vias corresponding to the adjacent two second wire parts 320 have the maximum spacing in the second direction Y under the premise of ensuring balanced connection via arrangement, maximally reduce the distribution density of the connection vias, and maximally ensure simple via process and good display effect. Taking Figure 5 For example, in the region far from the non-display area side of the first central axis a, the connection vias corresponding to the adjacent two second wire parts 320 all have a larger spacing in the second direction Y, i.e. a region with a smaller via distribution density, which can be a fine display region or a region with higher requirements for display uniformity, so that the fine display requirement or balanced display region can be ensured, and the multifunctionality or personalized display requirement of the display panel 10 can be ensured

[0047] Optionally, as shown in Figure 6 When i≤M, j=M-i+1; and when i>M, j=2M-i+1.

[0048] When i≤M, j=M-i+1; and when i>M, j=2M-i+1. Figure 6As shown, taking M = 3 as an example, when i ≤ M, that is, the first three connection wires 300, and the ith first wire part 310 is electrically connected with the (2j-1)th second wire part 320, if j = M-i+1 at the same time, for example, when i = 1, j = M-i+1 = 3, 2j-1 = 5, the first first connection wire part 310 (m1 in the figure) is electrically connected with the fifth second wire part 320 (s5 in the figure), when i = 2, j = M-i+1 = 2, 2j-1 = 3, the second first connection wire part 310 (m2 in the figure) is electrically connected with the third second wire part 320 (s3 in the figure), and when i = 3, j = M-i+1 = 1, 2j-1 = 1, the third first connection wire part 310 (m3 in the figure) is electrically connected with the first second wire part 320 (s1 in the figure).

[0049] Meanwhile, when i > M, the ith first wire part 310 is electrically connected with the (2j)th second wire part 320, and j = 2M-i+1, for example, i = 4, j = 2M-i+1 = 3, 2j = 6, the fourth first connection wire part 310 (m4 in the figure) is electrically connected with the sixth second wire part 320 (s6 in the figure), i = 5, j = 2M-i+1 = 2, 2j = 4, the fifth first connection wire part 310 (m5 in the figure) is electrically connected with the fourth second wire part 320 (s4 in the figure), i = 6, j = 2M-i+1 = 1, 2j = 2, the sixth first connection wire part 310 (m6 in the figure) is electrically connected with the second second wire part 320 (s2 in the figure). The connection mode of the first wire part 310 and the second wire part 320 provided by the embodiment can further ensure that any two adjacent second wire parts 320 correspondingly have a larger spacing in the second direction Y under the premise of ensuring balanced connection via hole arrangement, that is, reduce the distribution density of the connection via holes, avoid the problems of complex via hole process and influence on display caused by concentrated arrangement of the connection via holes, reduce the process difficulty of the display panel 10, and at the same time improve the display effect of the display panel 10.

[0050] Continuing to refer to Figures 3 to 6 As shown, the second wire part 320 is electrically connected with the first wire part 310 through the first connection via hole 330 and is electrically connected with the data line 100 through the second connection via hole 340; the distance between the first connection via hole 330 and the second connection via hole 340 corresponding to two second wire parts 320 is the same.

[0051] Wherein, the first connection via 330 and the second connection via 340 exist in the display panel 10, the first connection via 330 is arranged to realize the electrical connection between the first trace part 310 and the second trace part 320, and the second connection via 340 is arranged to realize the electrical connection between the second trace part 320 and the data line 100, by arranging the two kinds of vias, the electrical connection between the data line 100 and the pad 200 through the connection trace 300 is ensured, the stable transmission of the signal of the display panel 10 is ensured, and then the display effect of the display panel 10 is ensured.

[0052] Further, referring to Figures 1 to 6 It is shown that by adjusting the connection relationship of the first trace part 310 and the second trace part 320 at different positions, the first connection via 330 is evenly distributed, the concentration of the via arrangement is avoided, and then the influence of the via on the display effect of the display panel 10 is weakened.
