[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0050] Please refer to FIG. 1 and FIG. 2 , FIG. 1 is a plan view schematically illustrating a display panel according to some embodiments of the present application, and FIG. 2 is a cross-sectional view schematically illustrating a display panel according to some embodiments of the present application.

[0051] 1 , the display panel 100 includes a display area 100 a and a non-display area 100 b outside the display area 100 a. The non-display area 100 b includes a binding area 100 c located on one side of the display area 100 a.

[0052] The display panel 100 includes a driving unit 40 bound to the binding area 100c. The driving unit 40 is used to output a data signal. The driving unit 40 can be any one of a driving chip and a chip-on-film.

[0053] The display panel 100 also includes a plurality of spaced data lines 11 located in the display area 100a and a plurality of spaced connection lines 20 located in the display area 100a. A connection line 20 is connected between a data line 11 and a driving unit 40 to transmit a data signal output by the driving unit 40 to a corresponding data line 11. The plurality of connection lines 20 are bent in the display area 100a so that the plurality of connection lines 20 are connected one-to-one with the plurality of data lines 11. Each connection line 20 includes a first connection line 21 and a second connection line 22 that are connected to each other. The second connection line 22 is bent relative to the first connection line 21, that is, the second connection line 22 intersects and connects with the first connection line 21. A first connection line 21 is connected between a second connection line 22 and a data line 11.

[0054] The display panel 100 is symmetrically arranged about a line of symmetry AA' in a first direction x. The line of symmetry AA' is an imaginary line of symmetry. A plurality of connecting traces 20 are arranged on opposite sides of the line of symmetry AA'. The plurality of connecting traces 20 are also symmetrically arranged about the line of symmetry AA'. For example, the connecting trace 20A and the connecting trace 20B are symmetrically arranged about the line of symmetry AA'.

[0055] The display panel 100 further includes a plurality of fan-shaped connection lines 62 located in the non-display area 100 b. The plurality of fan-shaped connection lines 62 are located between the drive unit 40 and the display area 100 a and are arranged in a fan-shaped pattern. One fan-shaped connection line 62 connects one connection line 20 to the drive unit 40.

[0056] It should be noted that the multiple connection lines 20 are bent in the display area 100 a so that the multiple fan-shaped connection lines 62 occupy a smaller area in the non-display area 100 b , enabling the display panel 100 to achieve narrow-frame display.

[0057] As shown in FIG. 2 , the display panel 100 includes a base layer 30 , a first metal layer 31 , a second metal layer 32 and a light emitting device layer 37 .

[0058] The first metal layer 31 is disposed on the base layer 30 and includes a plurality of data lines 11. The first metal layer 31 may also include power signal lines and connecting portions. The plurality of data lines 11 are spaced apart from the power signal lines and the connecting portions.

[0059] The second metal layer 32 is disposed on the base layer 30 and is insulated from the first metal layer 31. The second metal layer 32 includes multiple connecting traces 20. Therefore, multiple connecting traces 20 are located on the same metal layer, which reduces the uneven brightness caused by the need to change the connection hole when a connecting trace 20 is located on a different conductive layer.

[0060] The light-emitting device layer 37 is disposed on the side of the first metal layer 31 and the second metal layer 32 away from the base layer 30. The light-emitting device layer 37 includes an anode layer 371, a light-emitting layer 373, and a cathode layer 374. The light-emitting layer 373 is disposed between the anode layer 371 and the cathode layer 374. The anode layer 371 is located on the side of the light-emitting layer 373 closer to the base layer 30 and includes a plurality of anodes 372 spaced apart. The light-emitting layer 373 may include an organic light-emitting layer 373 and a quantum dot light-emitting film. The material of the anode layer 371 includes at least one of a metal and a transparent conductive material. The material of the cathode layer 374 includes at least one of a metal and a transparent conductive material.

[0061] 3 , which is a partially enlarged schematic diagram of a display area in some embodiments of the present application, the plurality of anodes 372 include a first anode 3721 , a second anode 3722 , and a third anode 3723 , which are spaced apart.

[0062] It should be noted that since the light-emitting layer 373 is located on the anode layer 371, the flatness of the anode layer 371 will affect the flatness of the light-emitting layer 373. If the anode layer 371 is not flat, the light-emitting layer 373 will become uneven. If the light-emitting layer 373 is not flat, the display panel 100 will have a poor viewing angle symmetry problem when displaying, that is, at the symmetrical viewing angles of the display panel 100, the display effect of the display panel 100 will be different. In addition, the film layer below the anode layer 371 has an impact on the flatness of the multiple anodes 372. For example, the first metal layer 31 and the second metal layer 32 are both located below the anode layer 371. The second metal layer 32 and the first metal layer 31 have an impact on the flatness of the multiple anodes 372.

[0063] The light-emitting device layer 37 includes a plurality of sub-pixels, each of which includes a light-emitting layer. The plurality of sub-pixels includes a red sub-pixel, a blue sub-pixel, and a green sub-pixel. A pixel may include a blue sub-pixel or a green sub-pixel, or a pixel may include a red sub-pixel and a green sub-pixel. In other words, the plurality of sub-pixels adopt a pentile arrangement, but the arrangement is not limited thereto. The plurality of pixels are arranged along a first direction x and a second direction y.

[0064] Please refer to FIG3 and FIG4 , FIG4 is a schematic diagram of the partial structure of a connection line in FIG3 .

[0065] At least one first connecting line 21 includes multiple first-type connecting segments 211 extending along a first direction x, multiple second-type connecting segments 212 extending along the first direction x, and multiple third-type connecting segments 213 extending along a second direction y. The multiple first-type connecting segments 211 and the multiple second-type connecting segments 212 are arranged alternately and staggered along the first direction x. Adjacent first-type connecting segments 211 and second-type connecting segments 212 are connected to both sides of a third-type connecting segment 213 in the first direction x. The first direction x intersects the second direction y.

[0066] It should be noted that Figure 3 illustrates several connecting traces 20 located on one side of the symmetry line AA'. Since multiple connecting traces 20 are arranged on opposite sides of the symmetry line AA', the several connecting traces 20 located on the other side of the symmetry line AA' can be inferred based on Figure 3 and will not be repeated here.

[0067] In related art, when connecting lines are arranged in the display area, the first connecting lines extend in a straight line, which increases the probability of the first connecting lines overlapping the anode and the risk of a large overlapping area between the first connecting lines and the anode. This increases the risk of the first connecting lines causing unevenness in the anode.

[0068] To address shortcomings in the related art, in some embodiments of the present application, multiple first-type connecting segments 211 and multiple second-type connecting segments 212 are arranged alternately and staggered along the first direction x. This allows for greater flexibility in the placement of the first-type connecting segments 211 and second-type connecting segments 212 extending along the first direction x, facilitating their avoidance of multiple anodes 372. This improves the problem of poor viewing angle symmetry caused by uneven anodes when connecting traces are arranged in the display area to achieve a narrow bezel, as in the related art. Furthermore, adjacent first-type connecting segments 211 and second-type connecting segments 212 are connected to both sides of a third-type connecting segment 213 in the first direction x, achieving a connection between multiple first-type connecting segments 211 and multiple second-type connecting segments 212. In addition, the design of multiple first-type connecting segments 211, multiple second-type connecting segments 212, and multiple third-type connecting segments 213 enables the metal layout area of ​​a first connecting line 21 to be larger, and the metal layout area of ​​the connecting line 20 to be larger and more uniform, which can improve the uneven brightness problem of the display panel 100 in the screen-off state caused by uneven metal distribution.

[0069] Multiple first-type connection segments 211 of a first connection line 21 are aligned along the first direction x, multiple second-type connection segments 212 of a first connection line 21 are aligned along the first direction x, and multiple third-type connection segments 213 of a first connection line 21 are aligned along the first direction x.

[0070] In some embodiments, as shown in Figures 3 and 4, multiple first-type connecting segments 211 and multiple second-type connecting segments 212 are arranged alternately one-to-one along the first direction x, but this is not limited to this. Alternatively, two adjacent and connected first-type connecting segments 211 and one second-type connecting segment 212 may be arranged as a repeating unit along the first direction x. Alternatively, one first-type connecting segment 211 and two adjacent and connected second-type connecting segments 212 may be arranged as a repeating unit along the first direction x. Alternatively, two adjacent and connected first-type connecting segments 211 and two adjacent and connected second-type connecting segments 212 may be arranged as a repeating unit along the first direction x. Combinations of these arrangements are also possible.

[0071] In other embodiments, the staggered connecting segments extending along the first direction x may include, in addition to the first type connecting segments 211 and the second type connecting segments 212, three or more different connecting segments staggered along the first direction x. Furthermore, at least one connecting segment extending along the second direction y may be provided to connect the three or more different connecting segments.

[0072] In some embodiments, when adjacent first-type connecting segments 211 and second-type connecting segments 212 are staggered, the vertical spacing between adjacent first-type connecting segments 211 and second-type connecting segments 212 in the second direction y is less than or equal to the size of a third-type connecting segment 213 in the second direction y. The ratio of the size of a third-type connecting segment 213 in the second direction y to the size of a pixel of the display panel 100 in the second direction y may be n, where n is an integer greater than or equal to 1. For example, the ratio of the size of a pixel of the display panel 100 in the second direction y to the size of a third-type connecting segment 213 in the second direction y may be 1. Accordingly, the area occupied by a third-type connecting segment 213 in the second direction y is the same as the area occupied by an adjacent row of second anodes 3722 and a row of third anodes 3723, but the present invention is not limited thereto.

[0073] In some embodiments, the orthographic projections of at least one first-type connecting segment 211 and at least one second-type connecting segment 212 on the base layer 30 do not overlap with the orthographic projections of the multiple anodes 372 on the base layer 30. The orthographic projection of at least a portion of at least one third-type connecting segment 213 on the base layer 30 does not overlap with the orthographic projections of the multiple anodes 372 on the base layer 30. Therefore, the risk of unevenness of the multiple anodes 372 caused by at least a portion of the first-type connecting segment 211, the second-type connecting segment 212, and the third-type connecting segment 213 is reduced, the risk of unevenness of the light-emitting layer 373 is reduced, and the viewing angle symmetry of the connecting trace 20 when disposed in the display area 100a is improved.

[0074] In some embodiments, the orthographic projections of the plurality of first-type connecting segments 211 on the base layer 30 do not overlap with the orthographic projections of the plurality of anodes 372 on the base layer 30, that is, all of the first-type connecting segments 211 do not overlap with the plurality of anodes 372. In some embodiments, the orthographic projections of some first-type connecting segments 211 on the base layer 30 may not overlap with the orthographic projections of the plurality of anodes 372 on the base layer 30, while the orthographic projections of other first-type connecting segments 211 on the base layer 30 may overlap with the orthographic projection of at least one anode 372 on the base layer 30. In some embodiments, the first-type connecting segments 211 that overlap with the anodes 372 include a first portion and a second portion. The orthographic projection of the first portion on the base layer 30 does not overlap with the orthographic projections of the plurality of anodes 372 on the base layer 30, while the orthographic projection of the second portion on the base layer 30 overlaps with the orthographic projections of the plurality of anodes 372 on the base layer 30. The area of ​​the second portion is smaller than that of the first portion.

[0075] In some embodiments, the orthographic projections of the plurality of second-type connecting segments 212 on the base layer 30 may not overlap with the orthographic projections of the plurality of anodes 372 on the base layer 30, that is, all of the second-type connecting segments 212 do not overlap with the plurality of anodes 372. In some embodiments, the orthographic projections of some of the second-type connecting segments 212 on the base layer 30 may not overlap with the orthographic projections of the plurality of anodes 372 on the base layer 30, while the orthographic projections of another portion of the second-type connecting segments 212 on the base layer 30 may overlap with the orthographic projection of at least one anode 372 on the base layer 30.

[0076] It should be noted that, in design, the multiple first-type connection segments 211 and the multiple second-type connection segments 212 of a connection trace 20 avoid the multiple anodes 372, which can better ensure the viewing angle symmetry of the display panel 100 during display. However, in actual production, due to factors such as process accuracy, a portion of a first-type connection segment 211 and a portion of a second-type connection segment 212 may align with the anode 372, but the majority of a first-type connection segment 211 and a majority of a second-type connection segment 212 can still avoid the anode 372.

[0077] In some embodiments, the orthographic projection of at least one third-type connecting segment 213 on the base layer 30 does not overlap with the orthographic projections of the multiple anodes 372 on the base layer 30. In some embodiments, the orthographic projections of the multiple third-type connecting segments 213 on the base layer 30 do not overlap with the orthographic projections of the multiple anodes 372 on the base layer 30. In some embodiments, the third-type connecting segment 213 arranged to overlap with the anodes 372 includes a third portion and a fourth portion. The orthographic projection of the third portion on the base layer 30 does not overlap with the orthographic projections of the multiple anodes 372 on the base layer 30, and the orthographic projection of the fourth portion on the base layer 30 overlaps with the orthographic projections of the multiple anodes 372 on the base layer 30. The area of ​​the fourth portion is smaller than that of the third portion.

[0078] It should be noted that, in the present application, the direction of the orthographic projection is the direction in which the light-emitting device layer 37 points to the base layer 30 .

[0079] In some embodiments, as shown in FIG3 and FIG4 , the first type connecting segment 211 , the second type connecting segment 212 , and the third type connecting segment 213 may all extend in a straight line, thereby reducing the patterning process for forming the first connecting line 21 .

[0080] In other embodiments, at least one of the first-type connecting segment 211, the second-type connecting segment 212, and the third-type connecting segment 213 may also include at least one of a broken line segment and an arc segment. This allows at least one of the first-type connecting segment 211, the second-type connecting segment 212, and the third-type connecting segment 213 to better avoid the plurality of anodes 372.

[0081] In some embodiments, the third-type connecting segment 213 includes a first end and a second end that are opposite each other in the second direction y. The first-type connecting segment 211 and the second-type connecting segment 212 can both be connected between the first and second ends of the third-type connecting segment 213. Therefore, the first and second ends of the third-type connecting segment 213 are both non-connecting ends, meaning they are not connected to any other structure. It is understood that the third-type connecting segment 213 can also include more than two ends, for example, three ends.

[0082] In this application, the meaning of the non-connection end is relative to that of the connection end. The connection end is connected to other structures, while the non-connection end refers to an end that is not connected to other structures and is in a suspended state.

[0083] In other embodiments, one of the first and second connecting segments 211, 212 can be connected to one of the first and second ends of the third connecting segment 213, while the other of the first and second connecting segments 211, 212 is connected between the first and second ends of the third connecting segment 213. In this case, the other of the first and second ends of the third connecting segment 213 is a non-connected end. In still other embodiments, the first and second connecting segments 211, 212 can be connected to the first and second ends of the third connecting segment 213, respectively.

[0084] In some embodiments, at least one first connecting line 21 further includes a plurality of fourth-type connecting segments 214 extending along the second direction y. The plurality of fourth-type connecting segments 214 of a first connecting line 21 are aligned along the first direction x. Each fourth-type connecting segment 214 is located between two adjacent third-type connecting segments 213. The plurality of fourth-type connecting segments 214 are staggered relative to the plurality of third-type connecting segments 213 along the first direction x. Each fourth-type connecting segment 214 is connected to either a first-type connecting segment 211 or a second-type connecting segment 212.

[0085] In some embodiments of the present application, based on the design of the first type of connection segment 211, the second type of connection segment 212, and the third type of connection segment 213, a plurality of fourth type of connection segments 214 are added, which are staggered with the third type of connection segment 213. The end of the third type of connection segment 213 is staggered with the end of the fourth type of connection segment 214, and the gap adjacent to the end of the third type of connection segment 213 and the end of the fourth type of connection segment 214 can also be staggered. The distribution irregularity of the gaps between different connection traces 20 in the second metal layer 32 increases. The risk of obvious dark lines appearing on the display panel 100 when the screen is off is reduced, thereby improving the problem of uneven brightness of the display panel 100 when the screen is off.

[0086] It should be noted that the multiple connecting traces 20 are formed by removing portions of the entire initial metal layer, with the remaining metal forming a plurality of spaced-apart connecting traces 20. The second metal layer 32 has no metal in the gaps adjacent to the ends of the connecting segments. When the display panel 100 is in the off state, the reflectivity of the gaps is low, while the reflectivity of the connecting traces 20 is high. Increasing the irregularity of the gap distribution, so that the gaps are not aligned, can reduce the risk of noticeable dark lines, thereby improving the problem of linear brightness unevenness (i.e., line mura).

[0087] In some embodiments, each first connecting line 21 includes a plurality of fourth-type connecting segments 214 extending along the second direction y.

[0088] 3 and 4 , the fourth-type connecting segments 214 extend in straight lines to further reduce the difficulty of the patterning process for forming the first connecting lines 21. The fourth-type connecting segments 214 may also include broken line segments and / or arc segments.

[0089] In some embodiments, the fourth type of connecting segment 214 includes a first end and a second end that are opposite in the second direction y. The fourth type of connecting segment 214 is connected to a position between the two ends of a first type of connecting segment 211, or the fourth type of connecting segment 214 is connected to a position between the two ends of a second type of connecting segment 212. Therefore, the first end and the second end of the fourth type of connecting segment 214 are both non-connecting ends, that is, they are not connected to other structures. It is understandable that the fourth type of connecting segment 214 can also include more than two ends, for example, three ends. Since the fourth type of connecting segment 214 is staggered with the third type of connecting segment 213, the two non-connecting ends of the fourth type of connecting segment 214 are also staggered with the two non-connecting ends of the third type of connecting segment 213.

[0090] In some embodiments, the orthographic projection of at least one fourth-type connecting segment 214 on the base layer 30 overlaps with the orthographic projection of at least one anode 372 on the base layer 30 .

[0091] In a specific embodiment, the orthographic projection of at least one anode 372 on the base layer 30 is symmetrically arranged with respect to the orthographic projection of a fourth-type connecting segment 214 on the base layer 30. With this arrangement, when the orthographic projection of the fourth-type connecting segment 214 on the base layer 30 overlaps with the orthographic projection of at least one anode 372 on the base layer 30, the at least one anode 372 is symmetrically arranged with respect to the fourth-type connecting segment 214. This can also ensure that the luminous effects of light emitted by the light-emitting layer 373 on the anode 372 at symmetrical viewing angles are the same or tend to be the same, thereby ensuring viewing angle symmetry of the display panel 100 during display.

[0092] It should be noted that the fourth type of connecting segment 214 is introduced in this application to improve line mura. However, due to the limited spacing between the multiple anodes 372 due to the layout design, the fourth type of connecting segment 214 may overlap with the anodes 372. The orthographic projection of the anodes 372 on the substrate layer 30 is symmetrical with the orthographic projection of the fourth type of connecting segment 214 on the substrate layer 30, which can ensure viewing angle symmetry of the display panel 100. Therefore, in some embodiments of the present application, the fourth type of connecting segment 214 can achieve both improved line mura and good viewing angle symmetry.

[0093] In other embodiments, if conditions permit, the orthographic projection of at least one fourth-type connecting segment 214 on the base layer 30 may not overlap with the orthographic projections of the plurality of anodes 372 on the base layer 30 .

[0094] In some embodiments, the length of the first-type connecting segment 211 is greater than the length of the second-type connecting segment 212, and the fourth-type connecting segment 214 is connected to the first-type connecting segment 211. With this arrangement, when the first-type connecting segment 211 is longer, the plurality of fourth-type connecting segments 214 and the plurality of third-type connecting segments 213 can be evenly arranged in the first direction x, further improving the uniformity of the metal distribution in the second metal layer 32 and further improving the uneven brightness problem of the display panel 100 in the off state.

[0095] In some embodiments, in each connection trace 20, the spacing between the fourth-type connection segment 214 and two adjacent third-type connection segments 213 is equal in the first direction x. This arrangement allows the plurality of fourth-type connection segments 214 and the plurality of third-type connection segments 213 to be more evenly distributed in the first direction x, further improving the uniformity of the metal distribution in the second metal layer 32 and further alleviating the uneven brightness of the display panel 100 when the screen is off.

[0096] In some embodiments, the plurality of first connecting lines 21 of the plurality of connecting lines 20 are arranged along the second direction y. Each of at least two adjacent first connecting lines 21 includes a plurality of first-type connecting segments 211, a plurality of second-type connecting segments 212, a plurality of third-type connecting segments 213, and a plurality of fourth-type connecting segments 214. In a specific embodiment, as shown in Figures 3 and 4, the first connecting line 21 of each connecting line 20 includes a plurality of first-type connecting segments 211, a plurality of second-type connecting segments 212, a plurality of third-type connecting segments 213, and a plurality of fourth-type connecting segments 214. This arrangement allows the plurality of connecting lines 20 to have the same partial structural design, which helps simplify the manufacturing process of the plurality of connecting lines 20.

[0097] When the first connecting line 21 of each connecting trace 20 includes multiple first-class connecting segments 211, multiple second-class connecting segments 212, multiple third-class connecting segments 213 and multiple fourth-class connecting segments 214, for two adjacent first connecting lines 21, the multiple first-class connecting segments 211 of one first connecting line 21 and the multiple first-class connecting segments 211 of the other first connecting line 21 can be aligned in a one-to-one manner along the second direction y. Similarly, for two adjacent first connecting lines 21, the multiple second-type connecting segments 212 of one first connecting line 21 can be aligned one-to-one with the multiple second-type connecting segments 212 of the other first connecting line 21; the multiple third-type connecting segments 213 of one first connecting line 21 can be aligned one-to-one with the multiple third-type connecting segments 213 of the other first connecting line 21; and the multiple fourth-type connecting segments 214 of one first connecting line 21 can be aligned one-to-one with the multiple fourth-type connecting segments 214 of the other first connecting line 21. This arrangement further simplifies the manufacturing process of the first connecting lines 21 of the multiple connecting traces 20.

[0098] As shown in Figure 3, a first gap G1 is formed between two adjacent third-type connecting segments 213 of at least two adjacent first connecting lines 21 aligned along the second direction y, and a second gap G2 is formed between two adjacent fourth-type connecting segments 214 of at least two adjacent first connecting lines 21 aligned along the second direction y. The first gap G1 and the second gap G2 are staggered along the first direction x. This alleviates the line mura problem caused by the linear arrangement of multiple gaps, thereby improving the uneven brightness of the display panel 100 when the screen is off.

[0099] It should be noted that, when both ends of the third type connection segment 213 are non-connection ends, the first gap G1 is located between the two non-connection ends of two adjacent third type connection segments 213 aligned along the second direction y.

[0100] In some embodiments, the dimensions of the first gap G1 and the second gap G2 along the second direction y are greater than or equal to 1.8 microns and less than or equal to 3.5 microns. Alternatively, the dimensions of the first gap G1 and the second gap G2 along the second direction y are greater than or equal to 2 microns and less than or equal to 3 microns. If the dimensions of the first gap G1 and the second gap G2 along the second direction y are less than 1.8 microns, the process for forming the first gap G1 and the second gap G2 will be more difficult, and the risk of short circuits between two adjacent first connecting lines 21 will increase. If the dimensions of the first gap G1 and the second gap G2 along the second direction y are greater than 3.5 microns, the first gap G1 and the second gap G2 will be too large. The reflectivity of the areas corresponding to the first gap G1 and two adjacent third-type connecting segments 213 of the first gap G1 in the second direction y, and the reflectivity of the areas corresponding to the second gap G2 and two adjacent fourth-type connecting segments 214 of the second gap G2 in the second direction y, will differ significantly from the reflectivity of other areas with continuous connecting lines, increasing the risk of uneven brightness of the display panel 100 when the screen is off.

[0101] In some embodiments, at least one second connection line 22 includes a fifth-type connection segment 221 extending along the second direction y and multiple sixth-type connection segments 222 extending along the first direction x. The fifth-type connection segment 221 is located on the side of the first connection line 21 away from the data line 11 connected to the first connection line 21. The fifth-type connection segment 221 is connected to a first-type connection segment 211 or a second-type connection segment 212, and multiple sixth-type connection segments 222 are connected to a fifth-type connection segment 221.

[0102] It should be noted that the designs of the first connecting wire 21 and the second connecting wire 22 are not exactly the same, partly because the layout spaces of the first connecting wire 21 and the second connecting wire 22 are different. In some embodiments, the second connecting wire 22 can also adopt the design of the first connecting wire 21.

[0103] In some embodiments, as shown in Figures 3 and 4, multiple second connection lines 22 of the multiple connection lines 20 are arranged along the first direction x. Each of at least two adjacent second connection lines 22 includes a fifth type connection segment 221 and a plurality of sixth type connection segments 222. A third gap G3 is provided between two adjacent sixth type connection segments 222 aligned along the first direction x of at least two adjacent second connection lines 22, and the third gap G3 is staggered with the first gap G1 and the second gap G2 along the first direction x. This arrangement is used to further improve the line mura problem caused by the linear arrangement of multiple gaps, thereby improving the uneven brightness problem of the display panel 100 in the screen-off state. In a specific embodiment, each second connection line 22 includes a fifth type connection segment 221 and a plurality of sixth type connection segments 222.

[0104] In some embodiments of the present application, for each connecting trace 20, the data signal output by the driving unit 40 is transmitted via the fifth-type connecting segment 221 extending along the second direction y and multiple sixth-type connecting segments 222 extending along the first direction x to a first-type connecting segment 211 or a second-type connecting segment 212 connected to the fifth-type connecting segment 221, and then transmitted to the data line 11 via multiple first-type connecting segments 211, multiple second-type connecting segments 212, and the fourth-type connecting segment 214 connected via the third-type connecting segment 213. Therefore, the first-type connecting segment 211 to the sixth-type connecting segment 222, as a whole, implement the transmission of the data signal from the driving unit 40 to the data line 11.

[0105] In some embodiments, multiple sixth-category connecting segments 222 are connected to both sides of a fifth-category connecting segment 221 in the first direction x, but are not limited thereto. The lengths of the sixth-category connecting segments 222 located on the same side of the fifth-category connecting segment 221 may be the same or different. The sixth-category connecting segment 222 includes a first end and a second end opposite to each other in the first direction x. At least one of the first end and the second end of the sixth-category connecting segment 222 is a non-connecting end. In a specific embodiment, as shown in Figures 3 and 4, the first end of the sixth-category connecting segment 222 is a connecting end and is connected to the fifth-category connecting segment 221, and the second end of the sixth-category connecting segment 222 is a non-connecting end. In the first direction x, the gap between the second ends of two adjacent sixth-category connecting segments 222 is a third gap G3.

[0106] In some embodiments, a fourth gap G4 is provided between a third-type connecting segment 213 or a fourth-type connecting segment 214 adjacent to and aligned with a fifth-type connecting segment 221 in the second direction y. As shown in FIG4 , a fourth gap G4 is provided between a third-type connecting segment 213 adjacent to and aligned with a fifth-type connecting segment 221 in the second direction y.

[0107] In some embodiments, the dimension of the fourth gap G4 along the second direction y is greater than or equal to 1.8 microns and less than or equal to 3.5 microns. Optionally, the dimension of the fourth gap G4 along the second direction y is greater than or equal to 2 microns and less than or equal to 3 microns. The dimension of the third gap G3 along the first direction x is greater than or equal to 1.8 microns and less than or equal to 3.5 microns. Optionally, the dimension of the third gap G3 along the first direction x is greater than or equal to 2 microns and less than or equal to 3 microns. The design reasons for the dimensions of the third gap G3 and the fourth gap G4 are similar to those for the first gap G1 and the second gap G2 and are not further described here.

[0108] In some embodiments, the orthographic projection of at least one of the first gap G1, the second gap G2, the third gap G3, and the fourth gap G4 on the base layer 30 does not overlap with the orthographic projection of the plurality of anodes 372 on the base layer 30. In a specific embodiment, the orthographic projection of the first gap G1, the second gap G2, the fourth gap G4, and the third gap G3 on the base layer 30 does not overlap with the orthographic projection of the plurality of anodes 372 on the base layer 30. With this arrangement, the risk of unevenness caused by the gaps and the non-connected ends adjacent to the gaps leading to unevenness of the anodes 372 is reduced. The reduced risk of unevenness of the anodes 372 reduces the risk of unevenness of the light-emitting layer 373, thereby ensuring viewing angle symmetry of the display panel 100.

[0109] In some embodiments, as shown in FIG5 , the display panel 100 further includes a metal compensation pattern 41. The orthographic projection of the metal compensation pattern 41 on the base layer 30 overlaps with the orthographic projection of at least one of the first gap G1, the second gap G2, the fourth gap G4, and the third gap G3 on the base layer 30. With this arrangement, when the display panel 100 is in the off state, the metal compensation pattern 41 increases the reflectivity of the gaps, further reducing the risk of noticeable dark lines appearing on the display panel 100 when the screen is off. This improves the uneven brightness of the display panel 100 when the screen is off.

[0110] In some embodiments, the first metal layer 31 includes a metal compensation pattern 41. This arrangement allows the first metal layer 31 to compensate for the reflectivity at the gap, eliminating the need for a new metal layer to compensate for the reflectivity at the gap. This improves the uneven brightness of the display panel 100 when the screen is off, while simplifying the manufacturing process of the display panel 100.

[0111] In some embodiments, as shown in FIG. 5 , the metal compensation pattern 41 may be at least one of the data line 11 , the power signal line 311 , and the connection line 312 .

[0112] In a specific embodiment, the metal compensation pattern 41 may include a power signal line 311. Since the power signal line 311 is a metal wiring that occupies a relatively large area in the second metal layer 32, the use of the power signal line 311 can better meet the requirements of gap compensation at different locations.

[0113] In another specific embodiment, the metal compensation pattern 41 includes a data line 11, a power signal line 311, and a connection line 312. That is, the metal compensation pattern 41 includes multiple different types of lines. This increases the selectivity of the metal compensation pattern 41 and increases the flexibility of the layout of the first gap G1, the second gap G2, the fourth gap G4, and the third gap G3.

[0114] In some embodiments, another metal layer between the second metal layer 32 and the base layer 30 may be used, a metal layer above the second metal layer 32 may be used, or an additional metal layer may be provided above the second metal layer 32. In some embodiments, the anode layer 371, the gate metal layer 34, the electrode plate metal layer 35, and the source and drain metal layer 36 may include a metal compensation pattern 41.

[0115] In some embodiments, the metal compensation pattern 41 and the second metal layer 32 comprise the same material. This configuration allows the metal compensation pattern 41 and the second metal layer 32 to have the same reflectivity. In some embodiments, the metal compensation pattern 41 and the second metal layer 32 comprise at least one of copper, molybdenum, aluminum, and titanium.

[0116] In some embodiments, as shown in FIG2 , the display panel 100 further includes an insulating layer. The insulating layer is disposed between the first metal layer 31 and the second metal layer 32 and includes a plurality of vias Via. The plurality of connecting traces 20 are respectively connected to the plurality of data lines 11 through the plurality of vias Via. The orthographic projections of the plurality of vias Via on the base layer 30 are staggered with the orthographic projections of the plurality of anodes 372 on the base layer 30. With such a configuration, the unevenness of the film layer caused by the plurality of vias Via reduces the risk of unevenness of the plurality of anodes 372, reduces the risk of unevenness of the light-emitting layer 373, and thereby ensures the viewing angle symmetry of the display panel 100 during display.

[0117] In some embodiments, multiple data lines 11 extend along the second direction x. Therefore, the third and fourth connecting segments 213 and 214 extend in the same direction as the data lines 11, allowing the third and fourth connecting segments 213 and 214 to occupy a larger space in the second direction y. The first and second connecting segments 211 and 212 extend in directions that intersect with the direction of the data lines 11. The dimensions of the first and second connecting segments 211 and 212 can be designed to accommodate smaller spaces in the first direction x.

[0118] In some embodiments, as shown in FIG3 and FIG4 , the first direction x and the second direction y are perpendicular to each other, but are not limited thereto. The first direction x is the width direction of the display panel 100. The second direction y is the length direction of the display panel 100, but is not limited thereto.

[0119] In other embodiments, the first direction x and the second direction y may also intersect with the extension direction of the data line 11. For example, the angle between the second direction y and the extension direction of the data line 11 is an acute angle or an obtuse angle.

[0120] In some embodiments, as shown in Figures 1 and 6 , multiple connection traces 20 are located in a local area of ​​the display area 100a, that is, multiple connection traces 20 are located in the connection trace area 100a1. To increase the uniformity of metal distribution in the display area 100a, the second metal layer 32 further includes a compensation grid pattern 42 located in the display area 100a. The compensation grid pattern 42 is located in the compensation grid pattern area 100a2. The compensation grid pattern area 100a2 is adjacent to the connection trace area 100a1 and is located on the side of the connection trace area 100a1 away from the driving unit 40. The compensation grid pattern 42 is located on the side of the multiple connection traces 20 away from the binding area 100c. The compensation grid pattern 42 includes a plurality of interconnected metal grids 421, each metal grid 421 being arranged around a grid opening 424. Such a setting, using the design of the compensation grid pattern 42, can, on the one hand, improve the uniformity of the distribution of the metal of the compensation grid pattern 42, and on the other hand, improve the similarity between the compensation grid pattern 42 and the multiple connecting traces 20, so that the reflectivity of light in the area where the compensation grid pattern 42 is located is close to the reflectivity of light in the area where the multiple connecting traces 20 are located, further improving the problem of uneven brightness of the display panel 100 when the screen is off.

[0121] In some embodiments, the metal grid 421 is rectangular, but is not limited thereto. Each metal grid 421 includes first grid lines 422 extending along a first direction x and second grid lines 423 extending along a second direction y, with the first grid lines 422 connected to the second grid lines 423. In a specific embodiment, the metal grid 421 includes two parallel and oppositely disposed first grid lines 422 and adjacent parallel and oppositely disposed second grid lines 423. One first grid line 422 connects two adjacent second grid lines 423.

[0122] It should be noted that due to the special design of the multiple connecting traces 20 of the present application, the structure of the multiple connecting traces 20 is similar to that of the compensation grid pattern 42, which significantly improves the uniformity of the metal distribution of the second metal layer 32. The connecting traces 20 are arranged in the display area 100a, thereby achieving a narrow bezel design for the display panel 100 while improving the uneven brightness of the display panel 100 when the screen is off.

[0123] In some embodiments, as shown in FIG1 , the display area 100a further includes two corner compensation regions 100a3 located at two corners of the display area 100a. The second metal layer may also include a corner compensation grid pattern (not shown) located in the corner compensation regions 100a3. The design of the corner compensation grid pattern may be the same as that of the compensation grid pattern 42. The corner compensation regions 100a3 are located on the side of the compensation grid pattern region 100a2 near the binding region 100c. This further improves the uneven brightness of the display panel when the screen is off.

[0124] In some embodiments, as shown in FIG2 , the anode layer 371 further includes a bridging structure 61 located in the non-display area 100 b. The bridging structure 61 bridges the cathode layer 374 and the compensation grid pattern 42, connecting the cathode layer 374 to the compensation grid pattern 42. This reduces the resistance drop during the transmission of the constant voltage signal required by the cathode layer 374, thereby reducing the power consumption required by the display panel 100 during display. Furthermore, the design of the multiple metal grids 421 of the compensation grid pattern 42 significantly reduces the resistance drop during the transmission of the constant voltage signal.

[0125] In some embodiments, as shown in FIG2 , the display panel 100 further includes a semiconductor layer 33 , a gate metal layer 34 , and a source / drain metal layer 36 . The display panel 100 may further include an electrode plate metal layer 35 .

[0126] The semiconductor layer 33 is disposed on the base layer 30 , and the semiconductor layer 33 includes an active layer.

[0127] The gate metal layer 34 is located on a side of the semiconductor layer 33 away from the base layer 30. The gate metal layer 34 includes a gate, and the orthographic projection of the gate on the base layer 30 overlaps with the orthographic projection of the active layer on the base layer 30. A first insulating layer 51 is disposed between the semiconductor layer 33 and the gate metal layer 34.

[0128] The electrode plate metal layer 35 is located on the side of the gate metal layer 34 away from the base layer 30. A second insulating layer 52 is disposed between the electrode plate metal layer 35 and the gate metal layer 34. The electrode plate metal layer 35 also includes an electrode plate, the orthographic projection of the electrode plate on the base layer 30 overlapping the orthographic projection of the gate on the base layer 30. The electrode plate and the gate form the two plates of a capacitor.

[0129] The source / drain metal layer 36 is located on the side of the electrode plate metal layer 35 away from the base layer 30. A third insulating layer 53 is disposed between the source / drain metal layer 36 and the electrode plate metal layer 35. The source / drain metal layer 36 includes a source electrode 361 and a drain electrode 362 spaced apart from each other, and an initialization signal grid pattern 363. The source electrode 361 and the drain electrode 362 are connected to the active layer via vias that penetrate the third insulating layer 53, the second insulating layer 52, and the first insulating layer 51. The initialization signal grid pattern is located in the display area 100a and is used to transmit initialization signals.

[0130] The first metal layer 31 is located on a side of the source / drain metal layer 36 away from the base layer 30. A fourth insulating layer 54 is disposed between the first metal layer 31 and the source / drain metal layer 36. The first metal layer 31 also includes a first connecting portion 63, which is connected to the drain electrode 362 via a via extending through the fourth insulating layer 54.

[0131] The second metal layer 32 is disposed on a side of the first metal layer 31 away from the base layer 30. The insulating layer between the second metal layer 32 and the first metal layer 31 is a fifth insulating layer 55. The second metal layer 32 also includes a second connecting portion 64, which is connected to the first connecting portion 63 via a via hole that penetrates the fifth insulating layer 55.

[0132] The sixth insulating layer 56 is disposed between the anode layer 371 and the second metal layer 32 . The anode 372 is connected to the second connection portion 64 through a via hole penetrating the sixth insulating layer 56 , so that the transistor including the source 361 and the drain 362 is connected to the anode 372 .

[0133] A pixel definition layer 57 is provided on a side of the sixth insulating layer 56 away from the base layer 30. The pixel definition layer 57 includes a pixel opening 571 located in the display area 100a and a connection opening 572 located in the non-display area 100b. The light-emitting layer 373 is located in the pixel opening 571 and on the anode 372. The cathode layer 374 is connected to the bridge structure 61 through the connection opening 572. The bridge structure 61 is connected to the compensation grid pattern 42 through a via hole that penetrates the sixth insulating layer 56.
