Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a bending trace provided in the prior art. As shown in fig. 1, in the prior art, a plurality of hollowed-out holes are formed in a bending line. Wherein, the fretwork hole is provided with two, and these two fretwork holes all arrange along the extending direction of buckling the line of walking, and the fretwork hole all is not arranged in the same row.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a first implementation of a meander line according to an embodiment of the present disclosure. As shown in fig. 2, the bending trace 10 provided in the embodiment of the present invention includes a first hollow pattern 101 and a second hollow pattern 102. The first hollow pattern 101 includes first hollow holes 101a, and the first hollow holes 101a are arranged along a first direction X. The first direction X is perpendicular to the extending direction Y of the meandering trace 10. The first hollow patterns 101 and the second hollow patterns 102 are alternately arranged along the extending direction Y of the bending trace 10. The second hollow pattern 102 includes a second hollow hole 102a. The second hollow holes 102a are sequentially arranged along the first direction X, and the number of the second hollow holes 102a is greater than that of the first hollow holes 101 a.
It should be noted that, compared with the prior art, the bending trace 10 provided in the embodiment of the present application can further reduce the equivalent elastic modulus, so that the equivalent elastic modulus is lower. Therefore, when the bending trace 10 is bent at the same angle, the stress on the bending trace 10 is smaller, so as to better avoid the crack of the bending trace 10, thereby being beneficial to improving the yield of the display panel and achieving the effect of reducing the cost.
At least one first hollow hole 101a is formed in the same first hollow pattern 101. In the same second hollow pattern 102, at least one second hollow hole 102a is provided.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a second implementation of the meander trace according to the embodiment of the present application, and as shown in fig. 3, a difference between the meander trace 10 shown in fig. 3 and the meander trace 10 shown in fig. 2 is: the first hollow hole 101a includes a first symmetry axis M and a second symmetry axis N perpendicular to each other. . The second hollow hole 102a includes a third symmetry axis O and a fourth symmetry axis P perpendicular to each other.
It should be noted that, in the embodiment of the present application, the first hollow hole 101a and the second hollow hole 102a are axisymmetric patterns. When the first hollow hole 101a and the second hollow hole 102a are asymmetric images, the equivalent elastic modulus of the peripheral areas of the first hollow hole 101a and the second hollow hole 102a is not uniform, and the equivalent elastic modulus of a partial area is too large, so that when the bent trace 10 is bent, cracks are easily generated in the area. The first hollow holes 101a and the second hollow holes 102a are arranged to be axisymmetric images, so that the uniformity of equivalent elastic modulus of the peripheral areas of the first hollow holes 101a and the second hollow holes 102a can be improved, and cracks can be prevented from occurring when the bent wiring 10 is bent.
The first symmetry axis M is parallel to the extending direction of the bent trace 10, and the third symmetry axis O is parallel to the extending direction of the bent trace 10.
It should be noted that the extending direction of the folded trace 10 is the folding direction of the folded trace 10. The hollowed-out hole is formed in the bent trace 10, so that the equivalent elastic modulus of the bent trace 10 can be reduced. The first symmetry axis M is defined to be parallel to the extending direction of the bending trace 10, and the third symmetry axis O is parallel to the extending direction of the bending trace 10, so that the through holes formed in the bending trace 10 are uniformly distributed, the uniformity of the equivalent elastic modulus of the bending trace 10 can be ensured, and the problem that cracks are generated in the region when the bending trace 10 bends due to the fact that the equivalent elastic modulus of the partial region of the bending trace 10 is too large is avoided.
Referring to fig. 4, fig. 4 is a schematic structural view of a third implementation of the meander trace provided by the embodiment of the present application, as shown in fig. 4, a difference between the meander trace 10 shown in fig. 4 and the meander trace 10 shown in fig. 3 is: the second symmetry axis N is parallel to the extending direction of the bent trace 10, and the fourth symmetry axis P is parallel to the extending direction of the bent trace 10.
It should be noted that, since the short side of the bent trace 10 is too small, it is not beneficial to provide too many hollowed-out holes in the same row. The second symmetry axis N is parallel to the extending direction of the bending trace 10, and the fourth symmetry axis P is parallel to the extending direction of the bending trace 10, that is, the long sides of the first hollow hole 101a and the second hollow hole 102a are perpendicular to the extending direction of the bending trace 10, so as to increase the total occupied area of the first hollow hole 101a and the second hollow hole 102a, and further reduce the equivalent elastic modulus of the bending trace 10. Therefore, when the bending trace 10 is bent at the same angle, the stress on the bending trace 10 is smaller, so that the bending trace 10 can be better prevented from cracking, thereby being beneficial to improving the yield of the display panel and achieving the effect of reducing the cost.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a fourth implementation manner of a bending trace according to an embodiment of the present disclosure. As shown in fig. 5, the meander trace 10 shown in fig. 5 differs from the meander trace 10 shown in fig. 3 in that: both ends of the bent trace 10 are provided with first hollow patterns 101.
It should be noted that, because the two ends of the bent trace 10 are smaller in size, the two ends of the bent trace 10 are provided with the first hollow patterns 101 with a small number of hollow holes.
Referring to fig. 6, fig. 6 is a schematic structural diagram of a fifth implementation manner of a meander trace according to an embodiment of the present application. As shown in fig. 6, the meander trace 10 shown in fig. 6 differs from the meander trace 10 shown in fig. 5 in that: the first hollow hole 101a includes a first side 1011, a second side 1012, a third side 1013, and a fourth side 1014 connected in series. The first edge 1011 and the third edge 1013 are arc-shaped edges facing the inside of the first hollow hole 101 a. The second hollow hole 102a includes a fifth side 1021, a sixth side 1022, a seventh side 1023 and an eighth side 1024 which are connected end to end in sequence. The fifth edge 1021 and the seventh edge 1023 are arc-shaped edges facing the inside of the second hollow hole 102a.
It should be noted that, when the bending trace 10 is bent, the bending stress applied to the bending trace is in direct proportion to the length of the force arm, and by adopting the above arrangement, the force arm of the bending trace 10 when bent can be reduced, so as to reduce the bending stress applied to the bending trace 10 when bent. Therefore, the cracks of the bent routing wires can be better avoided when the wires are bent, the yield of the display panel is improved, and the effect of reducing the cost is achieved.
Referring to fig. 7, fig. 7 is a schematic structural diagram of a sixth implementation manner of a bending trace according to an embodiment of the present application. As shown in fig. 7, the meander trace 10 shown in fig. 7 differs from the meander trace 10 shown in fig. 6 in that: the first hollow hole 101a has an elliptical shape. The second hollow hole 102a has an elliptical shape.
It should be noted that the shape of the first hollow hole 101a and the shape of the second hollow hole 102a may also be circular or rectangular, and are not limited herein.
It should be noted that the stress concentration phenomenon exists in the peripheral areas of the first hollow hole 101a and the second hollow hole 102a, and the stress concentration phenomenon is more serious at a sharp point. Therefore, by setting the shape of the first hollow hole 101a and the shape of the second hollow hole 102a to be elliptical and circular, the stress concentration phenomenon existing in the first hollow hole 101a and the second hollow hole 102a can be reduced, which is beneficial to reducing the bending stress applied when the bending trace 10 is bent. Therefore, the cracks of the bent routing wires can be better avoided when the wires are bent, the yield of the display panel is improved, and the effect of reducing the cost is achieved.
Referring to fig. 8, fig. 8 is a schematic structural diagram of a seventh implementation manner of a bending trace according to an embodiment of the present disclosure. As shown in fig. 8, the meander trace 10 shown in fig. 8 differs from the meander trace 10 shown in fig. 7 in that: the distance D1 between the first hollow pattern 101 and the second hollow pattern 102 is smaller and smaller along the direction from the two ends of the bent trace 10 to the middle of the bent trace 10.
It should be noted that, when the bent trace 10 is bent, the pressure applied to the bent trace 10 is increasingly greater along the direction from the two ends of the bent trace 10 to the middle of the bent trace 10, and the smaller the distance D1 between the first hollow pattern 101 and the second hollow pattern 102 is, the lower the equivalent elastic modulus of the bent trace 10 is, so that the lower the bending flexibility applied to the bent trace 10 during bending is.
Therefore, the distance D1 between the first hollow pattern 101 and the second hollow pattern 102 is smaller and smaller along the direction from the two ends of the bent wire 10 to the middle of the bent wire 10, so that the bent wire 10 can be better prevented from cracking during bending, the yield of the display panel can be improved, and the effect of reducing the cost can be achieved.
The distance D1 between the first hollow pattern 101 and the second hollow pattern 102 is 8 nm to 12 nm. Specifically, the distance D1 between the first hollow pattern 101 and the second hollow pattern 102 is 8 micrometers, 8.5 micrometers, 9 micrometers, 9.7 micrometers, 10.4 micrometers, 11.2 micrometers, or 12 micrometers. The specific distance D1 between the first hollow pattern 101 and the second hollow pattern 102 is determined by the specific requirement of the bending trace 10.
The distance between adjacent first hollow holes 101a is 8 nm to 12 nm. Specifically, the pitch of the adjacent first hollow holes 101a is 8 micrometers, 8.5 micrometers, 9 micrometers, 9.7 micrometers, 10.4 micrometers, 11.2 micrometers, or 12 micrometers. The specific pitch of the adjacent first hollow holes 101a is determined by the specific requirement of the meander trace 10.
The distance between adjacent second hollow holes 102a is 8 nm to 12 nm. Specifically, the pitch of the adjacent second hollow holes 102a is 8 micrometers, 8.5 micrometers, 9 micrometers, 9.7 micrometers, 10.4 micrometers, 11.2 micrometers or 12 micrometers.
