Description

Technical Field

[0001] The present application relates to the field of display technologies, and particularly to a display panel and a display device. Background Art

[0002] Organic Light Emitting Diode (OLED) display panels have gradually become a new generation of display technologies due to their high contrast ratio, wide color gamut, low power consumption and other characteristics. With the development of OLED display panel technology, narrow bezel technology has become a differentiating technology to attract user groups. In order to implement narrow bezel technology, a technical solution of fan-out in active area (FIAA) is applied to OLED display panels. However, the technical solution of fan-out in active area will lead to poor viewing angle symmetry when the OLED display panel is displaying.

[0049] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0050] Please refer to Figure 1 and Figure 2 as shown in Figure 1 is a plan view of a display panel according to some embodiments of the present application, Figure 2 and is a cross-sectional structure view of a display panel according to some embodiments of the present application.

[0051] Please refer to Figure 1 as shown, the display panel 100 has a display area 100a and a non-display area 100b located outside the display area 100a. The non-display area 100b includes a bonding area 100c located on one side of the display area 100a.

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

[0053] The display panel 100 further includes a plurality of data lines 11 arranged at intervals in the display area 100a and a plurality of connection traces 20 arranged at intervals in the display area 100a. One connection trace 20 is connected between one data line 11 and the driving unit 40 to transmit the data signal output by the driving unit 40 to the corresponding data line 11. The plurality of connection traces 20 are bent in the display area 100a so that the plurality of connection traces 20 are respectively connected to the plurality of data lines 11 one by one. Each connection trace 20 includes a first connection line 21 and a second connection line 22 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 is connected to the first connection line 21. One first connection line 21 is connected between one second connection line 22 and one data line 11.

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

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

[0056] It should be noted that the plurality of connection traces 20 are bent in the display area 100a, so that the area occupied by the plurality of fan-shaped connection lines 62 in the non-display area 100b is small, enabling the display panel 100 to achieve narrow border display.

[0057] Please refer to Figure 2 As shown, 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 further include a power signal line and a connection portion. The plurality of data lines 11 are spaced apart from the power signal line and the connection portion.

[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 a plurality of connection traces 20. Therefore, the plurality of connection traces 20 are located in the same metal layer, improving the problem of uneven brightness caused by the need to connect through via holes when one connection trace 20 is located in different conductive layers.

[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 close to the base layer 30, and the anode layer 371 includes a plurality of spaced-apart anodes 372. The light-emitting layer 373 may include an organic light-emitting layer 373 and a quantum dot light-emitting film, etc. The material of the anode layer 371 includes at least one of metal and transparent conductive material. The material of the cathode layer 374 includes at least one of metal and transparent conductive material.

[0061] Please refer to Figure 3 , which is a partial enlarged schematic view of the display area of 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 that 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, it will cause the problem of unevenness of the light-emitting layer 373. The unevenness of the light-emitting layer 373 will cause the problem of poor viewing angle symmetry when the display panel 100 is displayed, that is, at the symmetric viewing angles of the display panel 100, there are differences in the display effects of the display panel 100. Moreover, the film layers below the anode layer 371 affect the flatness of multiple anodes 372. For example, the first metal layer 31 and the second metal layer 32 are both located below the anode layer 371, and the second metal layer 32 and the first metal layer 31 affect the flatness of multiple anodes 372.

[0063] The light-emitting device layer 37 includes multiple sub-pixels, and one sub-pixel includes one light-emitting layer. The multiple sub-pixels include red sub-pixels, blue sub-pixels, and green sub-pixels. One pixel may include one blue sub-pixel or one green sub-pixel, or one pixel may include one red sub-pixel and one green sub-pixel, that is, the multiple sub-pixels adopt the Pentile arrangement, but it is not limited thereto. The multiple pixels are arranged along the first direction x and the second direction y.

[0064] Please refer to Figure 3 and Figure 4 as shown in Figure 4 is Figure 3 a partial structural schematic diagram of a connection trace in it. At least one first connection line 21 includes multiple first-type connection segments 211 extending along the first direction x, multiple second-type connection segments 212 extending along the first direction x, and multiple third-type connection segments 213 extending along the second direction y. The multiple first-type connection segments 211 and the multiple second-type connection segments 212 are alternately and staggeredly arranged along the first direction x. An adjacent first-type connection segment 211 and a second-type connection segment 212 are connected to both sides of a third-type connection segment 213 in the first direction x. The first direction x intersects with the second direction y.

[0065] It should be noted that Figure 3 several connection traces 20 located on one side of the symmetry line AA' are schematically shown. Since multiple connection traces 20 are arranged on opposite sides of the symmetry line AA', several connection traces 20 located on the other side of the symmetry line AA' can be Figure 3 analogized, and details will not be described here.

[0066] In the related art, when the connection trace is arranged in the display area, the first connection line extends linearly, the probability of overlap between the first connection line and the anode increases, and the risk of having a large overlapping area between the first connection line and the anode also increases. The risk of the first connection line causing unevenness of the anode increases.

[0067] In view of the deficiencies in the related art, in some embodiments of the present application, multiple first - type connection segments 211 and multiple second - type connection segments 212 are alternately and staggeredly arranged along the first direction x. The arrangement positions of the first - type connection segments 211 and the second - type connection segments 212 extending along the first direction x are more flexible, which is conducive to the first - type connection segments 211 and the second - type connection segments 212 avoiding multiple anodes 372, and improving the problem of poor viewing - angle symmetry caused by the unevenness of the anode when the connection traces are arranged in the display area to achieve a narrow bezel in the related art. Moreover, an adjacent first - type connection segment 211 and a second - type connection segment 212 are connected to both sides of a third - type connection segment 213 in the first direction x, realizing the connection of multiple first - type connection segments 211 and multiple second - type connection segments 212. In addition, the design of multiple first - type connection segments 211, multiple second - type connection segments 212, and multiple third - type connection segments 213 makes the metal layout area of a first connection line 21 larger, and the metal layout area of the connection trace 20 larger and more uniform, which can improve the problem of uneven brightness that occurs in the display panel 100 in the off - screen state due to uneven metal distribution.

[0068] Multiple first - type connection segments 211 of a first connection line 21 are arranged in alignment along the first direction x, multiple second - type connection segments 212 of a first connection line 21 are arranged in alignment along the first direction x, and multiple third - type connection segments 213 of a first connection line 21 are arranged in alignment along the first direction x.

[0069] In some embodiments, such as Figure 3 and Figure 4 shown, multiple first - type connection segments 211 and multiple second - type connection segments 212 are alternately arranged one - to - one along the first direction x, but not limited to this. It is also possible to use two adjacent and connected first - type connection segments 211 and a second - type connection segment 212 as a repeating unit to be arranged along the first direction x. It is also possible to use a first - type connection segment 211 and two adjacent and connected second - type connection segments 212 as a repeating unit to be arranged along the first direction x. It is also possible to use two adjacent and connected first - type connection segments 211 and two adjacent and connected second - type connection segments 212 as a repeating unit to be arranged along the first direction x. It can also be a combination of the above - mentioned solutions.

[0070] In other embodiments, for the connection segments that are extended and staggeredly arranged along the first direction x, in addition to the design of the first - type connection segments 211 and the second - type connection segments 212, it is also possible to have three or more different connection segments staggeredly arranged along the first direction x. And at least one connection segment extending along the second direction y is provided to connect three or more different connection segments.

[0071] In some embodiments, when the adjacent first - type connection segments 211 and second - type connection segments 212 are arranged in a staggered manner, the vertical distance between the adjacent first - type connection segments 211 and second - type connection segments 212 in the second direction y is less than or equal to the dimension of a third - type connection segment 213 along the second direction y. The ratio of the dimension of a third - type connection segment 213 along the second direction y to the dimension of a pixel of the display panel 100 along the second direction y can be n, where n is an integer greater than or equal to 1. For example, the ratio of the dimension of a pixel of the display panel 100 along the second direction to the dimension of a third - type connection segment 213 along the second direction y can be 1. Correspondingly, the area occupied by a third - type connection segment 213 in the second direction y is the same as the area occupied by an adjacent row of second anodes 3722 and an adjacent row of third anodes 3723, but it is not limited thereto.

[0072] In some embodiments, the orthographic projection of at least one first - type connection segment 211 and at least one second - type connection segment 212 on the base layer 30 does not overlap with the orthographic projection of the plurality of anodes 372 on the base layer 30. At least a part of the orthographic projection of at least one third - type connection segment 213 on the base layer 30 does not overlap with the orthographic projection of the plurality of anodes 372 on the base layer 30. Therefore, the risk that at least a part of the first - type connection segments 211, second - type connection segments 212, and third - type connection segments 213 causes unevenness problems of the plurality of anodes 372 is reduced, the risk of unevenness of the light - emitting layer 373 is reduced, and the viewing - angle symmetry when the connection traces 20 are disposed in the display area 100a is improved.

[0073] In some embodiments, the orthographic projection of multiple first - type connection segments 211 on the base layer 30 does not overlap with the orthographic projection of the plurality of anodes 372 on the base layer 30, that is, all the first - type connection segments 211 do not overlap with the plurality of anodes 372. In some embodiments, it is also possible that the orthographic projection of some first - type connection segments 211 on the base layer 30 does not overlap with the orthographic projection of the plurality of anodes 372 on the base layer 30, and the orthographic projection of another part of the first - type connection segments 211 on the base layer 30 overlaps with the orthographic projection of at least one anode 372 on the base layer 30. In some embodiments, for the first - type connection segments 211 that overlap with the anode 372, the first - type connection segment 211 includes a first part and a second part. The orthographic projection of the first part on the base layer 30 does not overlap with the orthographic projection of the plurality of anodes 372 on the base layer 30, and the orthographic projection of the second part on the base layer 30 overlaps with the orthographic projection of the plurality of anodes 372 on the base layer 30. The area of the second part is smaller than the area of the first part.

[0074] In some embodiments, the orthographic projections of multiple second - type connection segments 212 on the base layer 30 may not overlap with the orthographic projections of multiple anodes 372 on the base layer 30, that is, all the second - type connection segments 212 do not overlap with the multiple anodes 372. In some embodiments, it is also possible that the orthographic projections of some of the second - type connection segments 212 on the base layer 30 do not overlap with the orthographic projections of multiple anodes 372 on the base layer 30, and the orthographic projections of the other part of the second - type connection segments 212 overlap with the orthographic projections of at least one anode 372 on the base layer 30.

[0075] It should be noted that in the design, multiple first - type connection segments 211 and multiple second - type connection segments 212 of a connection trace 20 avoid multiple anodes 372, which can better ensure the viewing - angle symmetry of the display panel 100 during display. However, in actual processes, affected by process precision and the like, parts of a first - type connection segment 211 and parts of a second - type connection segment 212 may overlap with the anode 372, but most of a first - type connection segment 211 and most of a second - type connection segment 212 can still avoid the anode 372.

[0076] In some embodiments, the orthographic projection of at least one third - type connection segment 213 on the base layer 30 does not overlap with the orthographic projection of multiple anodes 372 on the base layer 30. In some embodiments, the orthographic projections of multiple third - type connection segments 213 on the base layer 30 do not overlap with the orthographic projections of multiple anodes 372 on the base layer 30. In some embodiments, for the third - type connection segment 213 that is overlapped with the anode 372, the third - type connection segment 213 includes a third part and a fourth part. The orthographic projection of the third part on the base layer 30 does not overlap with the orthographic projection of multiple anodes 372 on the base layer 30, and the orthographic projection of the fourth part on the base layer 30 overlaps with the orthographic projection of multiple anodes 372 on the base layer 30. The area of the fourth part is smaller than the area of the third part.

[0077] It should be noted that in this application, the direction of the orthographic projection is the direction from the light - emitting device layer 37 towards the base layer 30.

[0078] In some embodiments, such as Figure 3 and Figure 4 shown, the first - type connection segment 211, the second - type connection segment 212, and the third - type connection segment 213 may all extend in a straight - line shape. By setting it in this way, the patterning process for forming the first connection line 21 is reduced.

[0079] In some other embodiments, at least one of the first type of connecting segments 211, the second type of connecting segments 212, and the third type of connecting segments 213 may also include at least one of a broken line segment and an arc segment. In this way, at least one of the first type of connecting segments 211, the second type of connecting segments 212, and the third type of connecting segments 213 can better avoid a plurality of anodes 372.

[0080] In some embodiments, the third type of connecting segment 213 includes a first end and a second end opposite to each other in the second direction y. The first type of connecting segments 211 and the second type of connecting segments 212 may both be connected between the first end and the second end of the third type of connecting segment 213. Therefore, both the first end and the second end of the third type of connecting segment 213 are non-connecting ends, that is, they are not connected to other structures. It can be understood that the third type of connecting segment 213 may further include more than two ends, for example, including three ends.

[0081] In the present application, the meaning of a non-connecting end is relative to the meaning of a connecting end. A connecting end is connected to other structures, while a non-connecting end refers to an end that is not connected to other structures, and this non-connecting end is in a suspended state.

[0082] In some other embodiments, one of the first type of connecting segments 211 and the second type of connecting segments 212 may be connected to one of the first end and the second end of the third type of connecting segment 213, and the other of the first type of connecting segments 211 and the second type of connecting segments 212 is connected between the first end and the second end of the third type of connecting segment 213. At this time, the other of the first end and the second end of the third type of connecting segment 213 is a non-connecting end. In still some other embodiments, the first type of connecting segments 211 and the second type of connecting segments 212 may be respectively connected to the first end and the second end of the third type of connecting segment 213.

[0083] In some embodiments, at least one first connecting line 21 further includes a plurality of fourth type of connecting segments 214 extending in the second direction y. The plurality of fourth type of connecting segments 214 of one first connecting line 21 are arranged in alignment in the first direction x. Each fourth type of connecting segment 214 is located between two adjacent third type of connecting segments 213. The plurality of fourth type of connecting segments 214 are respectively arranged in a staggered manner with the plurality of third type of connecting segments 213 in the first direction x. Each fourth type of connecting segment 214 is connected to one first type of connecting segment 211 or one second type of connecting segment 212.

[0084] In some embodiments of the present application, on the basis of designing 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 which are arranged in a staggered manner with respect to the third type of connection segment 213 are additionally provided. The end portions of the third type of connection segment 213 and the end portions of the fourth type of connection segment 214 are arranged in a staggered manner, and the gaps adjacent to the end portions of the third type of connection segment 213 and the end portions of the fourth type of connection segment 214 can also be arranged in a staggered manner. The irregularity of the distribution of the gaps between different connection traces 20 in the second metal layer 32 is increased. The risk of obvious dark lines appearing in the display panel 100 in the off-screen state is reduced, and further, the problem of uneven brightness of the display panel 100 in the off-screen state is improved.

[0085] It should be noted that the plurality of connection traces 20 are formed by removing a part of the initial metal layer on the entire surface, and the remaining metal forms the plurality of connection traces 20 arranged at intervals. There is no metal at the gaps adjacent to the end portions of the connection segments in the second metal layer 32. When the display panel 100 is in the off-screen state, the reflectivity at the gaps is relatively low, while the reflectivity of the connection traces 20 is relatively high. By increasing the irregularity of the distribution of the gaps and making the gaps not in a straight line, the risk of obvious dark lines can be improved, and further, the problem of linear brightness non-uniformity (i.e., line mura) can be improved.

[0086] In some embodiments, each first connection line 21 includes a plurality of fourth type of connection segments 214 extending along the second direction y.

[0087] In some embodiments, as Figure 3 and Figure 4 shown, the plurality of fourth type of connection segments 214 extend in a straight line shape to further reduce the difficulty of the patterning process for forming the first connection line 21. The plurality of fourth type of connection segments 214 can also include broken line segments and / or arc line segments.

[0088] In some embodiments, the fourth type of connection segment 214 includes a first end and a second end opposite to each other in the second direction y. The fourth type of connection segment 214 is connected to the positions between the two ends of a first type of connection segment 211, or the fourth type of connection segment 214 is connected to the positions between the two ends of a second type of connection segment 212. Therefore, both the first end and the second end of the fourth type of connection segment 214 are non-connection ends, that is, they are not connected to other structures. It can be understood that the fourth type of connection segment 214 can also include more than two end portions, for example, including three end portions. Since the fourth type of connection segment 214 is arranged in a staggered manner with respect to the third type of connection segment 213. The two non-connection ends of the fourth type of connection segment 214 and the two non-connection ends of the third type of connection segment 213 are also arranged in a staggered manner.

[0089] In some embodiments, the orthographic projection of at least one fourth type of connection segment 214 on the base layer 30 overlaps with the orthographic projection of at least one anode 372 on the base layer 30.

[0090] 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 of connection segment 214 on the base layer 30. With such an arrangement, when the orthographic projection of the fourth type of connection segment 214 on the base layer 30 overlaps with the orthographic projection of at least one anode 372 on the base layer 30, at least one anode 372 is symmetrically arranged with respect to a fourth type of connection segment 214, which can also ensure that the light-emitting effects of the light-emitting layer 373 on the anode 372 are the same or tend to be the same from a symmetric perspective, thereby ensuring the viewing angle symmetry when the display panel 100 is displaying.

[0091] It should be noted that the introduction of the fourth type of connection segment 214 in this application aims to improve the line mura problem. However, limited by the arrangement design of multiple anodes 372, the gap between multiple anodes 372 is limited. When the fourth type of connection segment 214 may overlap with the anode 372, the orthographic projection of the anode 372 on the base layer 30 being symmetrically arranged with respect to the orthographic projection of the fourth type of connection segment 214 on the base layer 30 can ensure the viewing angle symmetry when the display panel 100 is displaying. Therefore, the fourth type of connection segment 214 in some embodiments of this application can take into account improving line mura and good viewing angle symmetry.

[0092] In other embodiments, when conditions permit, the orthographic projection of at least one fourth type of connection segment 214 on the base layer 30 may also not overlap with the orthographic projection of multiple anodes 372 on the base layer 30.

[0093] In some embodiments, the length of the first type of connection segment 211 is greater than the length of the second type of connection segment 212, and the fourth type of connection segment 214 is connected to the first type of connection segment 211. With such an arrangement, when the first type of connection segment 211 is relatively long, multiple fourth type of connection segments 214 and multiple third type of connection segments 213 can be evenly arranged in the first direction x, further improving the uniformity of the distribution of the metal in the second metal layer 32 and further improving the problem of uneven brightness of the display panel 100 in the off-screen state.

[0094] In some embodiments, in the first direction x, in each connection trace 20, the distance between the fourth type of connection segment 214 and two adjacent third type of connection segments 213 is equal. With such an arrangement, multiple fourth type of connection segments 214 and multiple third type of connection segments 213 can be arranged more evenly in the first direction x, further improving the uniformity of the distribution of the metal in the second metal layer 32 and further improving the problem of uneven brightness of the display panel 100 in the off-screen state.

[0095] In some embodiments, multiple first connection lines 21 of multiple connection traces 20 are arranged along the second direction y. Each of at least two adjacent first connection lines 21 includes multiple first-type connection segments 211, multiple second-type connection segments 212, multiple third-type connection segments 213, and multiple fourth-type connection segments 214. In a specific embodiment, as Figure 3 and Figure 4 shown, the first connection line 21 of each connection trace 20 includes multiple first-type connection segments 211, multiple second-type connection segments 212, multiple third-type connection segments 213, and multiple fourth-type connection segments 214. With such a setting, the partial structures of multiple connection traces 20 are the same, which is beneficial to simplifying the manufacturing process of multiple connection traces 20.

[0096] When the first connection line 21 of each connection trace 20 includes multiple first-type connection segments 211, multiple second-type connection segments 212, multiple third-type connection segments 213, and multiple fourth-type connection segments 214, for two adjacent first connection lines 21, the multiple first-type connection segments 211 of one first connection line 21 and the multiple first-type connection segments 211 of the other first connection line 21 can be arranged in a one-to-one manner and aligned along the second direction y. Similarly, for two adjacent first connection lines 21, the multiple second-type connection segments 212 of one first connection line 21 and the multiple second-type connection segments 212 of the other first connection line 21 can be arranged in a one-to-one manner and aligned along the second direction y; the multiple third-type connection segments 213 of one first connection line 21 and the multiple third-type connection segments 213 of the other first connection line 21 can be arranged in a one-to-one manner and aligned along the second direction y; the multiple fourth-type connection segments 214 of one first connection line 21 and the multiple fourth-type connection segments 214 of the other first connection line 21 can be arranged in a one-to-one manner and aligned along the second direction y. With such a setting, the manufacturing process of the first connection lines 21 of multiple connection traces 20 is further simplified.

[0097] As Figure 3 shown, there is a first gap G1 between two adjacent third-type connection segments 213 that are aligned along the second direction y of at least two adjacent first connection lines 21, and there is a second gap G2 between two adjacent fourth-type connection segments 214 that are aligned along the second direction y of at least two adjacent first connection lines 21. The first gap G1 and the second gap G2 are arranged in a staggered manner along the first direction x. In this way, the line mura problem caused by the linear arrangement of multiple gaps is improved, and further, the brightness non-uniformity problem of the display panel 100 in the off-screen state is improved.

[0098] 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 that are aligned along the second direction y.

[0099] In some embodiments, the dimension of the first gap G1 and the second gap G2 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 first gap G1 and the second gap G2 along the second direction y is greater than or equal to 2 microns and less than or equal to 3 microns. When the dimension of the first gap G1 and the second gap G2 along the second direction y is less than 1.8 microns, the process difficulty of forming the first gap G1 and the second gap G2 will increase, and the risk of short circuit between two adjacent first connection lines 21 will increase. When the dimension of the first gap G1 and the second gap G2 along the second direction y is greater than 3.5 microns, the dimensions of the first gap G1 and the second gap G2 will be too large, and the reflectivity of the first gap G1 and the regions corresponding to two adjacent third-type connection segments 213 of the first gap G1 in the second direction y, the second gap G2 and the regions corresponding to two adjacent fourth-type connection segments 214 of the second gap G2 in the second direction y, will have a large difference from the reflectivity of other regions where continuous connection lines are provided, and the risk of uneven brightness of the display panel 100 in the off-screen state will be large.

[0100] In some embodiments, at least one second connection line 22 includes a fifth-type connection segment 221 extending along the second direction y and a plurality of 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 the plurality of sixth-type connection segments 222 are connected to a fifth-type connection segment 221.

[0101] It should be noted that the designs of the first connection line 21 and the second connection line 22 are not completely the same, partly because the layout spaces of the first connection line 21 and the second connection line 22 are different. In some embodiments, the second connection line 22 may also adopt the design of the first connection line 21.

[0102] In some embodiments, such as Figure 3 and Figure 4As shown, multiple second connection lines 22 of multiple connection traces 20 are arranged along the first direction x. Each of at least two adjacent second connection lines 22 includes a fifth type of connection segment 221 and multiple sixth type of connection segments 222. There is a third gap G3 between two adjacent sixth type of connection segments 222 that are aligned along the first direction x in at least two adjacent second connection lines 22. The third gap G3 is arranged offset from the first gap G1 and the second gap G2 along the first direction x. With such an arrangement, the line mura problem caused by the linear arrangement of multiple gaps is further improved, thereby improving the brightness non-uniformity problem of the display panel 100 in the off-screen state. In a specific embodiment, each second connection line 22 includes a fifth type of connection segment 221 and multiple sixth type of connection segments 222.

[0103] In some embodiments of the present application, for each connection trace 20, the data signal output by the driving unit 40 is transmitted to a first type of connection segment 211 or a second type of connection segment 212 connected to the fifth type of connection segment 221 through the fifth type of connection segment 221 extending along the second direction y and multiple sixth type of connection segments 222 extending along the first direction x, and then transmitted to the data line 11 through multiple first type of connection segments 211, multiple second type of connection segments 212, and a fourth type of connection segment 214 connected through the third type of connection segment 213. Therefore, the above first type of connection segment 211 to sixth type of connection segment 222, as a whole, realizes the transmission of the data signal from the driving unit 40 to the data line 11.

[0104] In some embodiments, multiple sixth type of connection segments 222 are connected to both sides of a fifth type of connection segment 221 in the first direction x, but it is not limited thereto. The lengths of the sixth type of connection segments 222 on the same side of the fifth type of connection segment 221 may be the same or different. The sixth type of connection segment 222 includes a first end and a second end that are opposite to each other in the first direction x. At least one of the first end and the second end of the sixth type of connection segment 222 is a non-connection end. In a specific embodiment, as Figure 3 and Figure 4 shown, the first end of the sixth type of connection segment 222 is a connection end and is connected to the fifth type of connection segment 221, and the second end of the sixth type of connection segment 222 is a non-connection end. In the first direction x, the gap between the second ends of two adjacent sixth type of connection segments 222 is the third gap G3.

[0105] In some embodiments, there is a fourth gap G4 between a third type of connection segment 213 or a fourth type of connection segment 214 that is adjacent to and aligned with the fifth type of connection segment 221 in the second direction y. As Figure 4 shown, there is a fourth gap G4 between a third type of connection segment 213 that is adjacent to and aligned with the fifth type of connection segment 221 in the second direction y.

[0106] 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 the same as those of the first gap G1 and the second gap G2, and will not be elaborated here.

[0107] 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 projections of the first gap G1, the second gap G2, the fourth gap G4, and the third gap G3 on the base layer 30 do not overlap with the orthographic projection of the plurality of anodes 372 on the base layer 30. With such a setting, the unevenness caused by the gaps and the non-connected ends adjacent to the gaps reduces the risk of unevenness of the anode 372. Reducing the risk of unevenness of the anode 372 reduces the risk of unevenness of the light-emitting layer 373, thereby ensuring the viewing angle symmetry of the display panel 100.

[0108] In some embodiments, as Figure 5 shown, the display panel 100 further includes a metal compensation pattern 41, and 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 such a setting, in the off-screen state of the display panel 100, the metal compensation pattern 41 improves the reflectivity at the gaps, further reducing the risk of obvious dark lines appearing in the display panel 100 in the off-screen state. The problem of uneven brightness of the display panel 100 in the off-screen state is improved.

[0109] In some embodiments, the first metal layer 31 includes the metal compensation pattern 41. With such a setting, the reflectivity at the gaps is compensated by using the first metal layer 31, avoiding adding a new metal layer to compensate the reflectivity at the gaps. While improving the problem of uneven brightness of the display panel 100 in the off-screen state, the manufacturing process of the display panel 100 is simplified.

[0110] In some embodiments, as Figure 5 shown, the metal compensation pattern 41 can be at least one of the data line 11, the power signal line 311, and the connection line 312.

[0111] In a specific embodiment, the metal compensation pattern 41 may include a power supply signal line 311. Since the power supply signal line 311 is a metal wiring that occupies a relatively large area in the second metal layer 32, using the power supply signal line 311 can better meet the compensation requirements for gaps at different positions.

[0112] In another specific embodiment, the metal compensation pattern 41 includes a data line 11, a power supply signal line 311, and a connection line 312, that is, the metal compensation pattern 41 includes various types of traces. In this way, the selectivity of the metal compensation pattern 41 is increased, and the flexibility of the layout positions of the first gap G1, the second gap G2, the fourth gap G4, and the third gap G3 can be increased.

[0113] In some embodiments, other metal layers between the second metal layer 32 and the base layer 30 can also be used, metal layers above the second metal layer 32 can also be used, and a metal layer can also be added 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-drain metal layer 36 described below may include the metal compensation pattern 41.

[0114] In some embodiments, the metal compensation pattern 41 and the second metal layer 32 are made of the same material. With this setting, the metal compensation pattern 41 and the second metal layer 32 have the same reflectivity. In some embodiments, the materials of the metal compensation pattern 41 and the second metal layer 32 include at least one of copper, molybdenum, aluminum, and titanium.

[0115] In some embodiments, in combination Figure 2 As shown, 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. A plurality of connection traces 20 are respectively connected to a 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 misaligned with the orthographic projections of the plurality of anodes 372 on the base layer 30. With this setting, due to the film layer unevenness caused by the plurality of vias Via, the risk of unevenness of the plurality of anodes 372 is reduced, the risk of unevenness of the light-emitting layer 373 is reduced, and thus the viewing angle symmetry during the display of the display panel 100 is ensured.

[0116] In some embodiments, the plurality of data lines 11 extend along the second direction x. Therefore, the extending directions of the third type of connection segment 213 and the fourth type of connection segment 214 are the same as the extending direction of the data line 11, and the third type of connection segment 213 and the fourth type of connection segment 214 can occupy a larger space in the second direction y. The extending directions of the first type of connection segment 211 and the second type of connection segment 212 intersect with the extending direction of the data line 11. The size design of the first type of connection segment 211 and the second type of connection segment 212 can be adapted to the smaller space in the first direction x.

[0117] In some embodiments, such as Figure 3 and Figure 4 shown, the first direction x is perpendicular to the second direction y, but is 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.

[0118] In other embodiments, the first direction x and the second direction y may also intersect with the extending direction of the data line 11. For example, the included angle between the second direction y and the extending direction of the data line 11 is an acute angle or an obtuse angle.

[0119] In some embodiments, please refer to Figure 1 and Figure 6 shown, a plurality of connecting traces 20 are located in a partial area of the display area 100a, that is, a plurality of connecting traces 20 are located in the connecting trace area 100a1. In order to improve the distribution uniformity of the metal 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 connecting trace area 100a1 and is located on the side of the connecting trace area 100a1 away from the driving unit 40. The compensation grid pattern 42 is located on the side of the plurality of connecting traces 20 away from the bonding area 100c. The compensation grid pattern 42 includes a plurality of interconnected metal grids 421. One metal grid 421 is arranged around a grid opening 424. With such a setting, by adopting the design of the compensation grid pattern 42, on the one hand, the distribution uniformity of the metal of the compensation grid pattern 42 can be improved, and on the other hand, the similarity between the compensation grid pattern 42 and the plurality of connecting traces 20 can be improved, so that the light reflectivity of the area where the compensation grid pattern 42 is located is similar to that of the area where the plurality of connecting traces 20 are located, and further improve the problem of uneven brightness of the display panel 100 in the off-screen state.

[0120] In some embodiments, the metal grid 421 is rectangular, but is not limited thereto. One metal grid 421 includes a first grid line 422 extending along the first direction x and a second grid line 423 extending along the second direction y. The first grid line 422 is connected to the second grid line 423. In a specific embodiment, the metal grid 421 includes two parallel and oppositely arranged first grid lines 422 and two adjacent parallel and oppositely arranged second grid lines 423. One first grid line 422 connects two adjacent second grid lines 423.

[0121] It should be noted that due to the special design of the multiple connection traces 20 of the present application, the structure of the multiple connection traces 20 is similar to the structure of the compensation grid pattern 42, significantly improving the metal distribution uniformity of the second metal layer 32. The connection traces 20 are arranged in the display area 100a so that while the display panel 100 realizes a narrow border design, the problem of uneven brightness of the display panel 100 in the off-screen state can be improved.

[0122] In some embodiments, as Figure 1 shown, 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 further include a corner compensation grid pattern (not shown) located in the corner compensation regions 100a3, and the design of the corner compensation grid pattern may be the same as the design of the compensation grid pattern 42. The corner compensation regions 100a3 are located on the side of the compensation grid pattern region 100a2 close to the bonding region 100c. In this way, the problem of uneven brightness of the display panel in the off-screen state can be further improved.

[0123] In some embodiments, as Figure 2 shown, the anode layer 371 further includes a bridging structure 61 located in the non-display area 100b. The bridging structure 61 bridges the cathode layer 374 and the compensation grid pattern 42, connecting the cathode layer 374 and the compensation grid pattern 42. In this way, the resistance voltage drop of the constant voltage signal required by the cathode layer 374 during transmission is reduced, and thus the power consumption required for the display of the display panel 100 is reduced. Moreover, the design of the multiple metal grids 421 of the compensation grid pattern 42 can significantly reduce the resistance voltage drop of the constant voltage signal during transmission.

[0124] In some embodiments, as Figure 2 shown, 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.

[0125] The semiconductor layer 33 is disposed on the base layer 30, and the semiconductor layer 33 includes an active layer.

[0126] The gate metal layer 34 is located on the 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. The first insulating layer 51 is disposed between the semiconductor layer 33 and the gate metal layer 34.

[0127] 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 provided between the electrode plate metal layer 35 and the gate metal layer 34. The electrode plate metal layer 35 further includes an electrode plate, and the orthographic projection of the electrode plate on the base layer 30 overlaps with the orthographic projection of the gate on the base layer 30. The electrode plate and the gate form two electrodes of a capacitor.

[0128] 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 provided 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, a drain electrode 362, and an initialization signal grid pattern 363 which are arranged at intervals. The source electrode 361 and the drain electrode 362 are connected to the active layer through vias penetrating 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 the initialization signal.

[0129] The first metal layer 31 is located on the side of the source-drain metal layer 36 away from the base layer 30. A fourth insulating layer 54 is provided between the first metal layer 31 and the source-drain metal layer 36. The first metal layer 31 further includes a first connection portion 63, and the first connection portion 63 is connected to the drain electrode 362 through a via penetrating the fourth insulating layer 54.

[0130] The second metal layer 32 is provided on the 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 the fifth insulating layer 55. The second metal layer 32 further includes a second connection portion 64, and the second connection portion 64 is connected to the first connection portion 63 through a via penetrating the fifth insulating layer 55.

[0131] The sixth insulating layer 56 is provided 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 penetrating the sixth insulating layer 56, so that the transistor including the source electrode 361 and the drain electrode 362 is connected to the anode 372.

[0132] A pixel defining layer 57 is provided on the side of the sixth insulating layer 56 away from the base layer 30. The pixel defining 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 bridging structure 61 through the connection opening 572. The bridging structure 61 is connected to the compensation grid pattern 42 through a via penetrating the sixth insulating layer 56.
