[0045] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The embodiments can be implemented in a plurality of different forms. A person skilled in the art can easily understand the fact that the method and content can be transformed into other forms without departing from the purpose and scope of the present invention. Therefore, the present invention should not be interpreted as being limited to the contents described in the following embodiments. In the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other arbitrarily.

[0046] In the drawings, the size of one or more components, the thickness of a layer, or an area is sometimes exaggerated for the sake of clarity. Therefore, one embodiment of the utility model is not necessarily limited to the size, and the shape and size of one or more components in the drawings do not reflect the true proportion. In addition, the drawings schematically show ideal examples, and one embodiment of the utility model is not limited to the shapes or values ​​shown in the drawings.

[0047] The ordinal numbers such as "first", "second", "third" and the like in this specification are provided to avoid confusion of constituent elements, rather than to limit the quantity. The "plurality" in this utility model means two or more.

[0048] In this specification, for the sake of convenience, the words and phrases indicating the orientation or positional relationship such as "middle", "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like are used to illustrate the positional relationship of the constituent elements with reference to the drawings. This is only for the convenience of describing this specification and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. The positional relationship of the constituent elements is appropriately changed according to the orientation of the constituent elements being described. Therefore, it is not limited to the words and phrases described in the specification and can be appropriately replaced according to the circumstances.

[0049] In this specification, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, or a detachable connection, or an integral connection; it can be a mechanical connection, or a connection; it can be a direct connection, or an indirect connection through an intermediate, or the internal communication of two elements. For ordinary technicians in this field, the meanings of the above terms in this utility model can be understood according to the circumstances.

[0050] In this specification, "electrical connection" includes the case where components are connected together through an element having some electrical function. There is no particular limitation on the "element having some electrical function" as long as it can transmit electrical signals between connected components. Examples of "element having some electrical function" include not only electrodes and wiring, but also switching elements such as transistors, resistors, inductors, capacitors, and other elements having multiple functions.

[0051] In this specification, a transistor refers to an element including at least three terminals: a gate, a drain, and a source. A transistor has a channel region between a drain (drain electrode terminal, a drain region, or a drain electrode) and a source (source electrode terminal, a source region, or a source electrode), and current can flow through the drain, the channel region, and the source. In this specification, a channel region refers to a region where current mainly flows.

[0052] In this specification, the first electrode may be a drain electrode and the second electrode may be a source electrode, or the first electrode may be a source electrode and the second electrode may be a drain electrode. In the case of using transistors with opposite polarities or when the current direction changes during circuit operation, the functions of the "source electrode" and the "drain electrode" are sometimes interchanged. Therefore, in this specification, the "source electrode" and the "drain electrode" may be interchanged. In addition, the gate electrode may also be called a control electrode.

[0053] In this specification, "parallel" means a state where the angle formed by two straight lines is greater than -10° and less than 10°, and therefore, also includes a state where the angle is greater than -5° and less than 5°. In addition, "perpendicular" means a state where the angle formed by two straight lines is greater than 80° and less than 100°, and therefore, also includes a state where the angle is greater than 85° and less than 95°.

[0054] In this specification, circles, ellipses, triangles, rectangles, trapezoids, pentagons or hexagons are not in the strict sense, but may be approximate circles, approximate ellipses, approximate triangles, approximate rectangles, approximate trapezoids, approximate pentagons or approximate hexagons, etc. There may be some small deformations caused by tolerances, such as chamfers, arc edges and deformations.

[0055] In this utility model, "approximately" and "roughly" mean that the limits are not strictly defined and the process and measurement errors are allowed. In this utility model, "roughly the same" means that the values ​​differ by less than 10%. In this utility model, "symmetric" means symmetric within the process and measurement errors.

[0056] In the present invention, A extends along direction B means that A may include a main part and a secondary part connected to the main part, the main part is a line, line segment or strip-shaped body, the main part extends along direction B, and the length of the main part extending along direction B is greater than the length of the secondary part extending along other directions. In the present invention, "A extends along direction B" means "the main part of A extends along direction B".

[0057] In the present invention, "the orthographic projection of B is within the range of the orthographic projection of A" or "the orthographic projection of A includes the orthographic projection of B" means that the boundary of the orthographic projection of B falls within the boundary of the orthographic projection of A, or the boundary of the orthographic projection of A overlaps with the boundary of the orthographic projection of B. The "shape of A" mentioned in the present invention refers to the shape of the orthographic projection of A on the substrate.

[0058] In the present invention, the distance between A and B refers to the vertical distance or the minimum distance between A and B.

[0059] In some implementations, the secondary screen of the large folding display needs to be designed with a cover. Usually, the appearance is an asymmetrical design, so that the center line of the display area and the center line of the lower frame are not on the same straight line, which puts forward new requirements for the signal routing layout of the lower frame.

[0060] The present embodiment provides a display substrate, comprising: a display area and a first frame area located at one side of the display area along a first direction, the first frame area comprising: a bending area, a first sub-area located between the bending area and the display area. The display area has a first center line extending along the first direction, and the first frame area has a second center line extending along the first direction. The distance between the first center line and the second center line is greater than 0. The display substrate comprises: a substrate, a plurality of sub-pixels and a plurality of data lines arranged on one side of the substrate and located in the display area, a plurality of first data fan-out lines located in the first sub-area, and a plurality of data bending lines located in the bending area. The plurality of data lines are electrically connected to the plurality of sub-pixels, and the plurality of data lines are configured to provide data signals to the plurality of sub-pixels. The plurality of first data fan-out lines are connected to the plurality of data lines. The plurality of data bending lines are connected to the plurality of first data fan-out lines, and the plurality of data bending lines are symmetrically arranged about a third center line. The third center line coincides with the first center line, or coincides with the second center line, or is located between the first center line and the second center line. Wherein, the extension directions of the third center line, the first center line, and the second center line may be the same.

[0061] In this embodiment, in view of the fact that the first center line of the display area and the second center line of the first frame area are not on the same straight line, the multiple data bending lines of the bending area are symmetrically arranged according to the third center line, which can ensure the density and film consistency of the data bending lines on both sides of the third center line, and facilitate the bending effect. Moreover, the third center line coincides with the first center line or the second center line, or is located between the first center line and the second center line, which can improve the problem caused by the signal routing difference caused by the asymmetric shape of the display substrate.

[0062] In some exemplary embodiments, the display substrate may further include: a plurality of first power bending lines located in the bending region and extending along the first direction, wherein the plurality of first power bending lines and the plurality of data bending lines are arranged at intervals along the second direction. The second direction intersects the first direction, for example, the second direction may be perpendicular to the first direction. The first frame region may further include: a second sub-region located on the side of the bending region away from the first sub-region. The display substrate may further include: a first peripheral power line located in the first sub-region and a first power lead-out line located in the second sub-region, wherein the first peripheral power line and the first power lead-out line may be connected through the plurality of first power bending lines. The plurality of first power bending lines may be arranged symmetrically about the third center line. In some examples, the first peripheral power line, the first power lead-out line and the plurality of first power bending lines are electrically connected and configured to transmit a first voltage signal. In this example, by arranging the plurality of first power bending lines in the bending region symmetrically about the third center line, the density and film consistency of the first power bending lines on both sides of the third center line may be ensured, and the transmission load consistency of the first voltage signal on both sides of the third center line may be ensured.

[0063] In some exemplary embodiments, the display substrate may further include: a plurality of second power meander lines extending along the first direction, the plurality of second power meander lines may be located on both sides of the plurality of data meander lines along the second direction. The display substrate may further include: a second peripheral power line located in the first sub-region and a second power lead-out line located in the second sub-region, the second peripheral power line and the second power lead-out line may be connected through the plurality of second power meander lines, and the second voltage signal transmitted by the second peripheral power line is different from the first voltage signal transmitted by the first peripheral power line. The plurality of second power meander lines may be symmetrically arranged about the third center line. In some examples, the first voltage signal may be greater than the second voltage signal. The first voltage signal may be configured to be provided to the first power line connected to the sub-pixel of the display area, and the second voltage signal may be configured to be provided to the cathode of the light-emitting element of the sub-pixel of the display area or the second power line connected to the sub-pixel. In this example, by arranging the plurality of second power meander lines of the bend area symmetrically about the third center line, the density and film consistency of the second power meander lines on both sides of the third center line may be ensured, and the transmission load consistency of the second voltage signal on both sides of the third center line may be ensured.

[0064] In some exemplary embodiments, the display substrate may further include: a plurality of control bending lines located in the bending region and extending along the first direction, the plurality of control bending lines being located on both sides of the plurality of second power supply bending lines along the second direction; the plurality of control bending lines may be symmetrically arranged about the third center line. In some examples, the plurality of control bending lines may include: a plurality of routing lines for providing control signals (e.g., including start signals, clock signals, voltage signals, etc.) to the gate drive circuit, and routing lines for transmitting panel test signals. The gate drive circuit may be configured to provide pixel control signals (e.g., including scan signals, reset signals, light emission control signals, etc.) to a plurality of sub-pixels in the display region. In this example, by arranging the plurality of control bending lines in the bending region symmetrically about the third center line, the density and film consistency of the control bending lines on both sides of the third center line may be ensured, and the transmission load consistency of the same control signal on both sides of the third center line may be ensured.

[0065] In some exemplary embodiments, the third center line may coincide with the second center line. The first frame area may have a first frame edge and a second frame edge extending along a first direction, and the first frame edge and the second frame edge may be located on both sides of the routing of the bending area along the second direction. The minimum distance between the routing of the bending area and the first frame edge is the first edge distance, the minimum distance between the routing of the bending area and the second frame edge is the second edge distance, and the ratio of the first edge distance to the second edge distance is 0.9 to 1.1. For example, the first edge distance may be equal to the second edge distance. This example can ensure the consistency of the distance between the routing of the bending area and the two side edges of the display panel, which is beneficial to the routing arrangement of the bending area and to ensure the bending effect.

[0066] In some exemplary embodiments, the third center line may be located between the first center line and the second center line, or the third center line may coincide with the first center line. The first border area may have a first border edge and a second border edge extending in a first direction, and the first border edge and the second border edge are located on both sides of the routing of the bending area along the second direction. The minimum distance between the routing of the bending area and the first border edge is the first edge distance, the minimum distance between the routing of the bending area and the second border edge is the second edge distance, and the ratio of the first edge distance to the second edge distance is greater than 1, or the ratio of the second edge distance to the first edge distance is greater than 1. In other words, the first edge distance is different from the second edge distance. This example helps to ensure the symmetrical arrangement of the routing of the bending area by adjusting the difference between the first edge distance and the second edge distance, thereby reducing the difference between the signals transmitted on both sides of the second center line in the first border area.

[0067] In some exemplary embodiments, the display substrate may include: a plurality of power bending lines located in the bending area, and the plurality of power bending lines and the plurality of data bending lines may be arranged at intervals along the second direction. The plurality of power bending lines may include: a first group of power bending lines and a second group of power bending lines located on both sides of the third center line, and the total length of the first group of power bending lines along the second direction may be different from the total length of the second group of power bending lines along the second direction. In some examples, the total length of a group of power bending lines along the second direction may include: the sum of the line width of each power bending line in the group of power bending lines, and the intervals between adjacent power bending lines. In this example, no other routing is arranged between adjacent power bending lines. In this example, the symmetrical arrangement of the plurality of data bending lines can be ensured by adjusting the total length of one or more groups of power bending lines on both sides of the third center line along the second direction.

[0068] In some examples, the third center line may coincide with the first center line, and the second center line and the first group of power meander lines may be located on the same side of the first center line. The total length of the first group of power meander lines along the second direction may be greater than the total length of the second group of power meander lines along the second direction. In this example, the routing arrangement of the first border area may be optimized by adjusting the lengths of the first group of power meander lines and the second group of power meander lines along the second direction.

[0069] The solution of this embodiment is described below by means of some examples.

The plurality of data lines may, for example, be located at a second source-drain metal layer, and the first power line of the display area may, for example, be located at a second source-drain metal layer. However, this embodiment is not limited thereto.

[0085] In some examples, such as Figure 2AAs shown, the light emitting structure layer 13 may include: a pixel definition layer 134 and a plurality of light emitting elements. For example, each light emitting element may include: a stacked first electrode 131, an organic light emitting layer 132 and a second electrode 133.

[0087] In some examples, the light-emitting layers of light-emitting elements of different colors may be different. For example, the red light-emitting element includes a red light-emitting layer, the green light-emitting element includes a green light-emitting layer, and the blue light-emitting element includes a blue light-emitting layer. In order to reduce the process difficulty and improve the yield, the hole injection layer and the hole transport layer on one side of the light-emitting layer may use a common layer, and the electron injection layer and the electron transport layer on the other side of the light-emitting layer may use a common layer.

For example, any one or more of the hole injection layer, the hole transport layer, the electron injection layer, and the electron transport layer corresponding to adjacent sub-pixels may be isolated. In some examples, the organic light-emitting layer can be formed by evaporation using a fine metal mask (FMM, FineMetal Mask) or an open mask (Open Mask), or by inkjet technology.

The second encapsulation layer 142 may be made of organic materials, for example, it may be a polymer material containing a desiccant or a polymer material that can block water vapor, or it may be a polymer resin, etc. to flatten the surface of the display substrate, and it may relieve the stress of the first encapsulation layer 141 and the third encapsulation layer 143, and it may also include a desiccant and other water-absorbing materials to absorb water, oxygen, and other substances that invade the interior. However, this embodiment is not limited to this. For example, the encapsulation structure layer may adopt a five-layer stacked structure of inorganic / organic / inorganic / organic / inorganic.

[0092] In some examples, such as Figure 1 As shown, the display area AA may have a first center line O1 extending along the first direction Y, and the first center line O1 passes through the center point C1 of the display area AA. For example, the distance between the first display edge and the center point C1 and the distance between the second display edge and the center point C1 may be the same; the distance between the third display edge and the center point C1 and the distance between the fourth display edge and the center point C1 may be the same.

Among them, the number of data lines in the first group of data lines and the number of data lines in the second group of data lines may be the same. For example, the first group of data lines and the second group of data lines may be symmetrically arranged about the first center line O1. However, this embodiment is not limited to this.

[0093] In this example, two groups of routing lines are symmetrically arranged about a center line, which means: the number of routing lines in the two groups of routing lines is the same, and the routing lines in the two groups of routing lines are symmetrically arranged about the center line, wherein the line widths of the routing lines symmetrically arranged about the center line in the two groups of routing lines are the same, and the spacing length between adjacent routing lines is the same. A group of routing lines is symmetrically arranged about a center line, which means: the group of routing lines can be divided into two parts located on both sides of the center line and arranged symmetrically, and the two parts include the same number of routing lines; or the group of routing lines can be divided into two parts located on both sides of the center line and arranged symmetrically and a routing line passing through the center line, and the two parts include the same number of routing lines.

[0094] Figure 3 Schematic diagram of the partial structure of the first border area of ​​at least one embodiment of the utility model. In some examples, such as Figure 1 and Figure 3 As shown, the frame area BB may include at least: a first frame edge B101 and a second frame edge B102 of the first frame area B1 that are relatively arranged in the second direction X, a third frame edge B201 and a fourth frame edge B301 that are relatively arranged in the second direction X. The first frame edge B101 and the second frame edge B102 may extend approximately along the first direction Y. For example, the first frame edge B101 and the second edge frame B102 may be linear edges parallel to each other. The first frame edge B101 is, for example, the left edge of the first frame area B1, and the second frame edge B102 is, for example, the right edge of the first frame area B1. The third frame edge B201 may be the left edge of the second frame area B2, and the right edge of the second frame area B2 is connected to the third display edge of the display area AA. The fourth frame edge B202 may be the right edge of the third frame area B3, and the left edge of the third frame area B3 is connected to the fourth display edge of the display area AA. The third frame edge B201 and the third display edge may be linear edges parallel to each other, and the fourth frame edge B301 and the fourth display edge may be linear edges parallel to each other. The first frame edge B101 and the third frame edge B201 may be connected by a curved frame edge, and the third frame edge B201 and the fourth frame edge B202 may be connected by a curved frame edge. The first frame edge B101 and the second frame edge B102 may be connected by a fifth frame edge B103 extending along the second direction X, and the third frame edge B201 and the fourth frame edge B301 may be connected by an edge of the fourth frame area B4 away from the display area AA.

[0095] In some examples, such as Figure 1 and Figure 3As shown, the first frame area B1 may have a second center line O2 extending along the first direction Y, and the second center line O2 passes through the center point C2 of the first frame area B1. The distance between the first frame edge B101 and the center point C2 may be substantially the same as the distance between the second frame edge B102 and the center point C2, and the distance between the first display edge and the center point C2 may be substantially the same as the distance between the fifth frame edge B103 and the center point C2. The second center line O2 may divide the first frame area B1 into a lower left frame area and a lower right frame area arranged along the second direction X. The second center line O2 may pass through the center point of the first signal access area B14. In other words, the center line of the first signal access area B14 extending along the first direction Y may coincide with the second center line O2. However, this embodiment is not limited to this. In other examples, the center line of the first signal access area B14 extending along the first direction Y may coincide with the first center line O1.

[0096] In some examples, the first frame edge B101 and the third frame edge B201 have a first distance L1 in the second direction X, and the second frame edge B102 and the fourth frame edge B301 have a second distance L2 in the second direction X. The first distance L1 is not equal to the second distance L2. For example, the first distance L1 may be less than the second distance L2. The display substrate of this example is an asymmetric structure as a whole, and the second center line O2 of the first frame area B1 and the first center line O1 of the display area AA do not overlap. For example, the second center line O2 may be located on one side of the first center line O1 in the opposite direction of the second direction X. In other examples, when the first distance L1 is greater than the second distance L2, the second center line O2 may be located on one side of the first center line O1 in the second direction X.

[0097] In some examples, such as Figure 3As shown, the bending area B12 may be provided with a group of signal bending lines, the group of signal bending lines including a plurality of signal bending lines (for example, including a plurality of data bending lines, a plurality of first power bending lines, a plurality of second power bending lines, and a plurality of control bending lines), and the plurality of signal bending lines may extend along the first direction Y and be arranged along the second direction X. The orthographic projection of the group of signal bending lines on the substrate may have a fourth center line O4 extending along the first direction Y. The group of signal bending lines may be symmetrically arranged about the fourth center line O4. For example, the fourth center line O4 may coincide with the third center line O3. The third center line O3 passes through the center point of the area corresponding to the orthographic projection of the group of signal bending lines on the substrate. For example, the area corresponding to the orthographic projection of the group of signal bending lines on the substrate may be roughly rectangular. The orthographic projection of the group of signal bend lines on the substrate may have a first routing edge B121 and a second routing edge B122, the first routing edge B121 may be an edge routing of the group of signal bend lines (e.g., the leftmost routing, such as the control bend line of the edge) close to the edge of the first frame edge B101, and the second routing edge B122 may be an edge routing of the group of signal bend lines (e.g., the rightmost routing, such as the control bend line of the edge) close to the edge of the second frame left edge B102. The first routing edge B121 and the second routing edge B122 may both extend approximately along the first direction Y. The distance between the first routing edge B121 and the third center line O3 and the distance between the second routing edge B122 and the third center line O3 may be approximately the same. The distance between the first routing edge B121 and the third center line O3 can be the sum of the line width and the spacing of multiple signal bending lines located on the side of the third center line O3 in the opposite direction of the second direction X; the distance between the second edge routing B122 and the third center line O3 can be the sum of the line width and the spacing of multiple signal bending lines located on the side of the third center line O3 in the second direction X.

[0098] In some examples, such as Figure 3 As shown, the bending area B12 can be provided with: four groups of data bending lines (for example, including a first group of data bending lines 311, a second group of data bending lines 312, a third group of data bending lines 313, and a fourth group of data bending lines 314), five groups of first power bending lines (for example, including a first group of first power bending lines 321, a second group of first power bending lines 322, a third group of first power bending lines 323, a third group of first power bending lines 324 and a fifth group of first power bending lines 325), two groups of second power bending lines (for example, including a first group of second power bending lines 331 and a second group of second power bending lines 332), and two groups of control bending lines (for example, including a first group of control bending lines 341 and a second group of control bending lines 342). Figure 3 , each group of data bending lines, each group of first power bending lines, each group of second power bending lines, each group of control bending lines, and each group of touch bending lines in the bending area B12 are schematically illustrated as a whole.

[0099] In some examples, each group of data meander lines may include a plurality of data meander lines arranged along the second direction X, the line widths of the plurality of data meander lines may be the same, and the spacings between adjacent data meander lines may be the same. Each group of first power meander lines may include a plurality of first power meander lines arranged along the second direction X. The line widths of the plurality of first power meander lines may be the same, and the spacings between adjacent first power meander lines may be the same. The plurality of first power meander lines within the same group of first power meander lines may be interconnected. Each group of second power meander lines may include a plurality of second power meander lines arranged along the second direction X, the line widths of the plurality of second power meander lines may be the same, and the spacings between adjacent second power meander lines may be the same. The plurality of second power meander lines within the same group of second power meander lines may be interconnected. Each group of control meander lines may include a plurality of control meander lines arranged along the second direction X. The line widths of the control meander lines transmitting the same signal may be the same, and the spacings between adjacent control meander lines may be the same.

[0100] In some examples, the plurality of signal bending lines in the bending region B12 may be located in the same conductive film layer, for example, in the second source-drain metal layer. However, this embodiment is not limited to this. For example, the plurality of signal bending lines may be located in the first source-drain metal layer, or in the third source-drain metal layer.

[0101] In some examples, the first group of control bending lines 341, the first group of second power bending lines 331, the fourth group of first power bending lines 324, the third group of data bending lines 313, the second group of first power bending lines 322, the first group of data bending lines 311, the first group of first power bending lines 321, the second group of data bending lines 312, the third group of first power bending lines 323, the fourth group of data bending lines 314, the fifth group of first power bending lines 325, the second group of second power bending lines 332, and the second group of control bending lines 342 can be arranged in sequence along the second direction X.

[0102] In some examples, the plurality of data bending lines may be symmetrically arranged about the third center line O3. The number of data bending lines in the first group of data bending lines 311 and the number of data bending lines in the second group of data bending lines 312 may be the same, and the first group of data bending lines 311 and the second group of data bending lines 312 may be symmetrically arranged about the third center line O3; the number of data bending lines in the third group of data bending lines 313 and the number of data bending lines in the fourth group of data bending lines 314 may be the same, and the third group of data bending lines 313 and the fourth group of data bending lines 314 may be symmetrically arranged about the third center line O3.

[0103] In some examples, a plurality of first power meander lines may be symmetrically arranged about the third center line O3. Among them, the first group of first power meander lines 321 may be arranged symmetrically about the third center line O3. The number of first power meander lines in the second group of first power meander lines 322 may be the same as the number of first power meander lines in the third group of first power meander lines 323, and the second group of first power meander lines 322 and the third group of first power meander lines 323 may be arranged symmetrically about the third center line O3. The number of first power meander lines in the fourth group of first power meander lines 324 may be the same as the number of first power meander lines in the fifth group of first power meander lines 325, and the fourth group of first power meander lines 324 and the fifth group of first power meander lines 325 may be arranged symmetrically about the third center line O3.

[0104] In some examples, the total length of the first group of first power bending lines 321 along the second direction X may be greater than the total length of the second group of first power bending lines 322 along the second direction X, and greater than the total length of the fourth group of first power bending lines 324 along the second direction X; the total lengths of the second group of first power bending lines 322, the third group of first power bending lines 323, the fourth group of first power bending lines 324, and the fifth group of first power bending lines 325 along the second direction X may be substantially the same. However, this embodiment is not limited to this. For example, the total lengths of the second group of first power bending lines 322 and the third group of first power bending lines 323 along the second direction X may be substantially the same, the total lengths of the fourth group of first power bending lines 324 and the fifth group of first power bending lines 325 along the second direction X may be substantially the same, and the total lengths of the second group of first power bending lines 322 and the fourth group of first power bending lines 324 along the second direction X may be different. Taking a group of first power bending lines including N first power bending lines as an example, the total length of the group of first power bending lines along the second direction may include: the line width of the N first power bending lines in the group of first power bending lines and the sum of the lengths of N-1 adjacent intervals.

[0105] In some examples, the plurality of second power bending lines may be symmetrically arranged about the third center line O3. The number of second power bending lines in the first group of second power bending lines 331 and the number of second power bending lines in the second group of second power bending lines 332 may be the same, and the first group of second power bending lines 331 and the second group of second power bending lines 332 may be symmetrically arranged about the third center line O3.

[0106] In some examples, a plurality of control bend lines may be symmetrically arranged about the third center line O3. The number of control bend lines in the first group of control bend lines 341 and the number of control bend lines in the second group of control bend lines 342 may be the same, and the first group of control bend lines 341 and the second group of control bend lines 342 may be symmetrically arranged about the third center line O3. In some examples, the control bend lines in the first group of control bend lines 341 or the second group of control bend lines 342 may include: effective control bend lines and invalid control bend lines; when the number of effective control bend lines in the first group of control bend lines 341 and the number of effective control bend lines in the second group of control bend lines 342 are different, invalid control bend lines may be arranged to ensure that the number of control bend lines in the first group of control bend lines 341 and the second group of control bend lines 342 are consistent and symmetrically arranged about the third center line O3.

[0107] In some examples, the third center line O3 may coincide with the second center line O2. In other words, the plurality of signal bending lines of the bending area B12 may be symmetrically arranged about the second center line O2.

[0108] In some examples, the minimum distance between the first routing edge B121 and the first frame edge B101 is the first edge distance a, and the minimum distance between the second routing edge B122 and the second frame edge B102 is the second edge distance b. The ratio of the first edge distance a to the second edge distance b may be 0.9 to 1.1, for example, the first edge distance a may be equal to the second edge distance b. For example, the first edge distance a may be greater than or equal to 0.4 mm, and the second edge distance b may be greater than or equal to 0.4 mm.

[0109] In this example, the signal bending line of the bending area B12 is set symmetrically about the second center line O2, and the first edge distance a and the second edge distance b are roughly the same, which can reduce the wiring differences in the lower left frame and the lower right frame, and is beneficial to reducing the transmission load differences of the same signal in the lower left frame and the lower right frame.

[0110] Figure 4 for Figure 3 A partial enlarged schematic diagram of the middle area S1. Figure 4 The first group of data bending lines 311, the second group of data bending lines 312 and the first group of first power bending lines 321 are schematically shown as a whole. Figure 4As shown, the plurality of data lines in the display area AA may be divided into a first group of data lines DL1a and a second group of data lines DL1b according to the first center line O1, and the number of data lines in the first group of data lines DL1a and the number of data lines in the second group of data lines DL1b may be the same. For example, the first group of data lines DL1a and the second group of data lines DL1b may be arranged symmetrically about the first center line O1. For example, the plurality of data lines may be located in the second source-drain metal layer or the third source-drain metal layer.

[0111] In some examples, such as Figure 4 As shown, the first sub-region B11 may be provided with a plurality of first data fan-out lines. The plurality of first data fan-out lines may include a first group of first data fan-out lines 211 and a second group of first data fan-out lines 212. The first group of first data fan-out lines 211 may be connected to the first group of data lines DLa, and the second group of first data fan-out lines 212 may be connected to the second group of data lines DLb. The first group of first data fan-out lines 211 may include a plurality of first data fan-out lines 21a, and the plurality of first data fan-out lines 21a may be electrically connected to the plurality of data lines in the first group of data lines DLa in a one-to-one correspondence. The second group of first data fan-out lines 212 may include a plurality of first data fan-out lines 21b, and the plurality of second data fan-out lines 21b may be electrically connected to the plurality of data lines in the second group of data lines DLb in a one-to-one correspondence. For example, the plurality of first data fan-out lines may be alternately arranged in the first gate metal layer and the second gate metal layer, and the orthographic projections of adjacent first data fan-out lines on the substrate may not overlap.

[0112] In some examples, the first data fan-out line 21a may include: a first data extension segment 21-1a and a second data extension segment 21-2a connected to each other. The second data extension segment 21-2a may be connected to at least one data bending line in a group of data bending lines (e.g., the first group of data bending lines 311). The first data extension segment 21-1a may be located on a side of the second data extension segment 21-2a close to the display area AA. The second data extension segment 21-2a may be a straight line segment extending along the first direction Y, and the extension direction of the first data extension segment 21-1a may intersect with the first direction Y, for example, the first data extension segment 21-1a may be an oblique line segment whose extension direction intersects with both the first direction Y and the second direction X.

[0113] In some examples, the first data fan-out line 21b may include: a first data extension segment 21-1b and a second data extension segment 21-2b connected to each other. The second data extension segment 21-2b may be connected to at least one data bending line in a group of data bending lines (e.g., a second group of data bending lines 312). The first data extension segment 21-1b may be located on a side of the second data extension segment 21-2b close to the display area AA. The second data extension segment 21-2b may be a straight line segment extending along the first direction Y, and the extension direction of the first data extension segment 21-1b may intersect with the first direction Y, for example, the first data extension segment 21-1b may be an oblique line segment whose extension direction intersects with both the first direction Y and the second direction X.

[0114] In some examples, the length of the first data extension segment 21-1a of at least one first data fan-out line (e.g., first data fan-out line 21a) close to the first center line O1 and located on a first side (e.g., left side) of the first center line O1 may be greater than the length of the first data extension line 21-1b of at least one first data fan-out line (e.g., first data fan-out line 21b) close to the first center line O1 and located on a second side (e.g., right side) of the first center line O1. The length of the second data extension segment 21-2a of at least one first data fan-out line 21a close to the first center line O1 may be less than the length of the second data extension line 21-2b of at least one first data fan-out line 21b close to the first center line O1. In this example, by setting the length of the first data extension segment 21-1a to be greater than the length of the first data extension segment 21-1b, the symmetric center line of the data bending line in the bending area B12 can be moved to the side opposite to the first center line O1 along the second direction X. For example, the symmetric center line of multiple data bending lines in the bending area B12 (i.e., the third center line O3) can be made to coincide with the second center line O2.

[0115] In some examples, the second sub-region B13 may be provided with a plurality of data lead lines. The plurality of data lead lines may include at least: a first group of data lead lines 411 and a second group of data lead lines 412. The first group of data lead lines 411 may be connected to the first group of data bending lines 311, and the second group of data lead lines 412 may be connected to the second group of data bending lines 312. The number of data lead lines on both sides of the second center line O2 may be the same, and the data lead lines on both sides of the second center line O2 may not be arranged symmetrically about the second center line O2. For example, a plurality of data lead lines may be alternately arranged in the first gate metal layer and the second gate metal layer, and the orthographic projections of adjacent data lead lines on the substrate may not overlap. However, this embodiment is not limited to this. In other examples, the data lead lines on both sides of the second center line O2 may be arranged symmetrically about the second center line O2.

[0116] In this example, the multiple signal bending lines of the bending area B12 can be symmetrically arranged about the third center line O3, and the third center line O3 can coincide with the second center line O2, thereby ensuring the consistency of the signal bending lines in the areas on both sides of the second center line O2, and ensuring the bending effect. For example, the arrangement of this example can ensure that the routing loads transmitting the same signal in the bending areas on both sides of the second center line O2 are consistent, thereby avoiding display problems caused by inconsistent signal loads.

[0117] In some examples, the plurality of first data fan-out lines in the first sub-area B11 are not symmetrically arranged about the second center line O2, and the plurality of data lead-out lines in the second sub-area B13 are not symmetrically arranged about the second center line O2. The plurality of data contact pads arranged in the first signal access area B14 may be symmetrically arranged about the second center line O2, and the plurality of data lead-out lines may be connected to the plurality of data contact pads. For example, the second sub-area B13 may be provided with a data load compensation structure to achieve load uniformity of the data signal transmitted in the first border area.

[0118] In some examples, the second sub-region B13 may include a second fan-out region and a third fan-out region. The plurality of data lead-out lines may include: a plurality of second data fan-out lines located in the second fan-out region and a plurality of third data fan-out lines located in the third fan-out region. The data load compensation structure may be located in at least one of the second fan-out region and the third fan-out region of the second sub-region, and the data load compensation structure may be connected in series with the data lead-out lines in the second sub-region; for example, the data load compensation structure may be located in the second fan-out region and connected in series with the second data fan-out line, or may be located in the third fan-out region and connected in series with the third data fan-out line. In some examples, the data load compensation structure may be a serpentine routing line, and the resistance is increased by increasing the length of the data lead-out line. A serpentine routing line is a meandering curve. For example, after one end of the routing line extends a distance in one direction, it bends and twists and extends a distance in the opposite direction of the direction, bends and twists again and extends in the direction, and bends and twists several times to form a serpentine routing line.

[0119] In other examples, the resistance can be increased by thinning the data lead lines in the second sub-region to perform load compensation. Alternatively, the resistance can be increased by increasing the number of jumpers between multiple line segments of the data lead lines in the second sub-region to perform load compensation. Alternatively, the resistance can be increased by setting the data lead lines in the second sub-region in a conductive layer with a higher resistivity.

[0120] In other examples, the resistance can be reduced by increasing the line width of the data lead line in the second sub-region to perform load compensation. Alternatively, the resistance can be reduced by setting the data lead line in the second sub-region as a double-layer or multi-layer routing. Alternatively, the data lead line in the second sub-region can be set in a conductive layer with a lower resistivity to reduce the resistance. This embodiment does not limit the load compensation method for the data signal in the first border region.

For example, the plurality of first data fan-out lines may be alternately arranged in the first gate metal layer and the second gate metal layer, or may all be located in the first gate metal layer, or may all be located in the second gate metal layer.

[0125] In some examples, the first peripheral power line 22 can be a single-layer routing located in the first source-drain metal layer, or can be a single-layer routing located in the second source-drain metal layer, or can be a double-layer routing located in the first source-drain metal layer and the second source-drain metal layer. The first peripheral power line 22 may include a first power main body extending along the second direction X and a plurality of first power connection parts (e.g., three first connection parts) extending along the first direction Y. The three first power connection parts may be electrically connected to three groups of first power bending lines (e.g., including a first group of first power bending lines 321, a second group of first power bending lines 322, and a third group of first power bending lines 323) in a one-to-one correspondence. For example, a first power connection part and a correspondingly connected group of first power bending lines may be an integrated structure connected to each other. In some examples, the first peripheral power line 22 may be roughly symmetrical about the third center line O3.

[0126] In some examples, the second peripheral power lines 231 and 232 may be located on a side of the first power main body of the first peripheral power line 22 away from the display area AA. The second peripheral power line 231 may extend to the second frame area B2, and the second peripheral power line 232 may extend to the third frame area B3. The second peripheral power line 231 may be located on one side of the third center line O3, and the second peripheral power line 232 may be located on the other side of the third center line O3.

[0127] In some examples, the first group of peripheral control lines 241 may be located on one side of the third center line O3, and the second group of peripheral control lines 242 may be located on the other side of the third center line O3. The first group of peripheral control lines 241 may extend to the second border area B2, and the second group of peripheral control lines 242 may extend to the third border area B3.

The plurality of peripheral control lines may be located on one side of the second peripheral power lines 231 and 232 close to the substrate, for example, may be located in the first gate metal layer or the second gate metal layer.

[0128] In some examples, the second sub-region B13 may be provided with a first power lead 42, second power lead 431 and 432, a plurality of control lead (e.g., including a first group of control lead 441 and a second group of control lead 442), and a plurality of data lead (e.g., including a first group of data lead, a second group of data lead, a third group of data lead 413, and a fourth group of data lead 414). The third group of data lead 413, the first group of data lead, the second group of data lead, and the fourth group of data lead 414 may be arranged along the second direction X.

The three second power connection portions can be electrically connected to the first group of first power bending lines 321, the second group of first power bending lines 322, and the third group of first power bending lines 323 in a one-to-one correspondence, so as to achieve electrical connection with the first peripheral power line 22 in the first sub-area B11. In some examples, the first power lead 42 can be a single-layer routing located in the first source and drain metal layer, or can be a single-layer routing located in the second source and drain metal layer, or can be a double-layer routing located in the first source and drain metal layer and the second source and drain metal layer.

[0130] In some examples, the second power lead 431 may be located on one side of the first power lead 42 in the opposite direction of the second direction X, and the second power lead 432 may be located on one side of the first power lead 42 in the second direction X. The second power lead 431 may be connected to the first group of second power bending lines 331 and the third group of second power bending lines 333 to achieve electrical connection with the second peripheral power lines 231 in the first sub-region B11; the second power lead 432 may be connected to the second group of second power lead 332 and the fourth group of second power lead 334 to achieve electrical connection with the second peripheral power lines 232 in the first sub-region B11. For example, the second power lead 431 and the second power lead 432 may be substantially symmetrical about the third center line O3. In some examples, the second power lead lines 431 and 432 can be single-layer wiring located in the first source-drain metal layer, or can be single-layer wiring located in the second source-drain metal layer, or can be double-layer wiring located in the first source-drain metal layer and the second source-drain metal layer.

[0131] In some examples, the first power lead 42 is configured to transmit a first voltage signal, and the second power lead 431 and 432 are configured to transmit a second voltage signal. The first voltage signal is different from the second voltage signal. For example, the first voltage signal may be greater than the second voltage signal. The first voltage signal may be configured to be provided to a pixel circuit of a sub-pixel in a display area, and the second voltage signal may be configured to be provided to a cathode of a light-emitting element of a sub-pixel in a display area. This embodiment is not limited to this.

[0132] In some examples, the first group of control lead wires 441 can be connected to the first group of control bending lines 341 to achieve electrical connection with the first group of peripheral control lines 241 in the first sub-region B11; the second group of control lead wires 442 can be connected to the second group of control bending lines 342 to achieve electrical connection with the second group of peripheral control lines 242 in the first sub-region B11. The multiple control lead wires may include: a line that provides a signal (such as a start signal, a clock signal, a voltage signal, etc.) to the gate drive circuit, a line that transmits a panel test signal, etc.

[0133] The signal bending lines of the bending area B12 of this example can be symmetrically arranged about the third center line O3, and the third center line O3 can coincide with the second center line O2, and the first edge distance a and the second edge distance b are roughly the same, which can ensure the density of the routing of the bending area B12 in the area on both sides of the second center line O2 and the consistency of the film layer, so as to ensure the bending performance. This example can ensure the load consistency of the signals transmitted by the first group of control bending lines 341 and the second group of control bending lines 342, and avoid display problems caused by inconsistent signal loads on both sides. This example can also ensure the transmission load consistency of the first voltage signal and the second voltage signal on both sides of the second center line. This example can also ensure that the space of the first border area is maximized. The remaining structures of the first border area of ​​this example can refer to the description of the aforementioned embodiment, so they will not be repeated here.

[0134] Figure 7 FIG. 1 is another partial schematic diagram of the first border area of ​​at least one embodiment of the utility model. In some examples, such as Figure 7 As shown, the bending area B12 can be provided with: four groups of data bending lines (for example, a first group of data bending lines 311, a second group of data bending lines 312, a third group of data bending lines 313 and a fourth group of data bending lines 314), three groups of first power bending lines (for example, a first group of first power bending lines 321, a second group of first power bending lines 322, a third group of first power bending lines 323), two groups of second power bending lines (for example, a first group of second power bending lines 331 and a second group of second power bending lines 332) and two groups of control bending lines (for example, a first group of control bending lines 341 and a second group of control bending lines 342).

[0135] In some examples, the first group of control bending lines 341, the first group of second power bending lines 331, the third group of data bending lines 313, the second group of first power bending lines 322, the first group of data bending lines 311, the first group of first power bending lines 321, the second group of data bending lines 312, the third group of first power bending lines 323, the fourth group of data bending lines 314, the second group of second power bending lines 332 and the second group of control bending lines 342 can be arranged in sequence along the second direction X.

[0136] In some examples, the first group of data bending lines 311 and the second group of data bending lines 312 can be symmetrically arranged about the third center line O3, the second group of data bending lines 313 and the fourth group of data bending lines 314 can be symmetrically arranged about the third center line O3, the first group of first power bending lines 321 can be symmetrically arranged about the third center line O3, the second group of first power bending lines 322 and the third group of first power bending lines 323 can be symmetrically arranged about the third center line O3, the first group of second power bending lines 331 and the second group of second power bending lines 332 can be symmetrically arranged about the third center line O3, and the first group of control bending lines 341 and the second group of control bending lines 342 can be symmetrically arranged about the third center line O3.

[0137] In some examples, the fourth center line O4 coincides with the third center line O3. The third center line O3 may coincide with the second center line O2. The first edge distance a and the second edge distance b may be substantially the same. In this example, by setting a group of signal bending lines of the bending area B12 symmetrically about the second center line O2, and the first edge distance a and the second edge distance b are substantially the same, the wiring differences within the lower left frame and the lower right frame can be reduced, which is conducive to reducing the transmission load differences of the same signal within the lower left frame and the lower right frame.

[0138] The rest of the description about the first border area of ​​this example can refer to the description of the aforementioned embodiment, so it will not be repeated here.

[0139] Figure 8 Another partial schematic diagram of the first border area of ​​at least one embodiment of the utility model. Fig. 9 for Figure 8 Schematic diagram of a partial enlargement of region S2 in FIG. Figure 8 and Fig. 9 As shown, the multiple signal bending lines in the bending area B12 may include: four groups of data bending lines (for example, including a first group of data bending lines 311, a second group of data bending lines 312, a third group of data bending lines 313 and a fourth group of data bending lines 314), five groups of first power bending lines (for example, including a first group of first power bending lines 321, a second group of first power bending lines 322, a third group of first power bending lines 323, a fourth group of first power bending lines 324 and a fifth group of first power bending lines 325), two groups of second power bending lines (for example, including a first group of second power bending lines 331, a second group of second power bending lines 332), and two groups of control bending lines (for example, including a first group of control bending lines 341 and a second group of control bending lines 342).

[0140] In some examples, such as Figure 8As shown, the first group of control bending lines 342, the first group of second power bending lines 331, the fourth group of first power bending lines 324, the third group of data bending lines 313, the second group of first power bending lines 322, the first group of data bending lines 311, the first group of first power bending lines 321, the second group of data bending lines 313, the third group of first power bending lines 323, the fourth group of data bending lines 314, the fifth group of first power bending lines 325, the second group of second power bending lines 332 and the second group of control bending lines 342 can be arranged in sequence along the second direction X.

[0141] In some examples, the plurality of signal bending lines of the bending area B12 may have a fourth center line O4 extending along the first direction Y, and the fourth center line O4 may coincide with the third center line O3. For example, the plurality of signal bending lines may be symmetrically arranged about the third center line O3. The orthographic projection of the routing of the bending area B12 on the substrate may have a first routing edge B121 and a second routing edge B122 extending along the first direction Y, the first routing edge B121 may be a left edge of the routing, and the second routing edge B122 may be a right edge of the routing. The distance between the third center line O3 and the first routing edge B121 and the distance between the third center line O3 and the second routing edge B122 may be the same.

[0142] In some examples, the distance between the third center line O3 and the second center line O2 in the second direction X may be greater than 0. The third center line O3 may not overlap with the second center line O2. For example, the third center line O3 may be located between the second center line O2 and the first center line O1. The distance between the third center line O3 and the first center line O1 may be the same as the distance between the third center line O3 and the second center line O2, or may be different. The first center line O1 may be located on one side of the second center line O2 in the second direction X. However, this embodiment is not limited to this. In other examples, the third center line O3 may overlap with the first center line O1.

[0143] In some examples, the minimum distance between the first routing edge B121 and the first frame edge B101 is the first edge distance a, and the minimum distance between the second routing edge and the second frame edge B102 is the second edge distance b. The first edge distance a may be different from the second edge distance b. For example, the ratio of the first edge distance a to the second edge distance b may be greater than 1. In other words, the first edge distance a may be greater than the second edge distance b. Among them, the first edge distance a may be greater than or equal to 0.4 mm, and the second edge distance b may be greater than or equal to 0.4 mm.

[0144] In some examples, such as Fig. 9As shown, the first sub-region B11 may be provided with a plurality of first data fan-out lines. The plurality of first data fan-out lines may include a first group of first data fan-out lines 211 and a second group of first data fan-out lines 212. The first group of first data fan-out lines 211 may be connected to the first group of data lines DLa, and the second group of first data fan-out lines 212 may be connected to the second group of data lines DLb. The first group of first data fan-out lines 211 may include a plurality of first data fan-out lines 21a, and the plurality of first data fan-out lines 21a may be electrically connected to the plurality of data lines in the first group of data lines DLa in a one-to-one correspondence. The second group of first data fan-out lines 212 may include a plurality of first data fan-out lines 21b, and the plurality of second data fan-out lines 21b may be electrically connected to the plurality of data lines in the second group of data lines DLb in a one-to-one correspondence.

[0145] In some examples, the first data fan-out line 21a may include a first data extension segment 21-1a and a second data extension segment 21-2a connected to each other. The second data extension segment 21-2a may be connected to at least one data bend line in a group of data bend lines (e.g., the first group of data bend lines 311). The first data extension segment 21-1a may be located on a side of the second data extension segment 21-2a close to the display area AA. The second data extension segment 21-2a may be a straight line segment extending along the first direction Y, and the extension direction of the first data extension segment 21-1a may intersect with the first direction Y, for example, the first data extension segment 21-1a may be an oblique line segment whose extension direction intersects with both the first direction Y and the second direction X.

[0146] In some examples, the first data fan-out line 21b may include a first data extension segment 21-1b and a second data extension segment 21-2b connected to each other. The second data extension segment 21-2b may be connected to at least one data bend line in a group of data bend lines (e.g., a second group of data bend lines 312). The first data extension segment 21-1b may be located on a side of the second data extension segment 21-2b close to the display area AA. The second data extension segment 21-2b may be a straight line segment extending along the first direction Y, and the extension direction of the first data extension segment 21-1b may intersect with the first direction Y, for example, the first data extension segment 21-1b may be an oblique line segment whose extension direction intersects with both the first direction Y and the second direction X.

[0147] In some examples, the length of the first data extension segment 21-1a of at least one first data fan-out line 21a near the first center line O1 may be greater than the length of the first data extension line 21-1b of at least one first data fan-out line 21b near the first center line O1. In this example, the length ratio of the first data extension segment 21-1a of the first data fan-out line 21a to the first data extension segment 21-b of the first data fan-out line 21b may be less than Figure 4The length ratio of the first data extension segment 21 - 1 a of the first data fan-out line 21 a to the first data extension segment 21 - b of the first data fan-out line 21 b in the illustrated embodiment can reduce the load difference between the first data fan-out lines on both sides of the first center line O1 .

[0148] In this example, the routing of the bending area B12 can be arranged roughly symmetrically about the third center line O3. By adjusting the first edge distance a and the second edge distance b (for example, the first edge distance a is greater than the second edge distance b), the third center line O3 can be located between the second center line O2 and the first center line O1, reducing the load difference between the first data fan-out lines in the first sub-area B11, thereby facilitating the compensation of the data signal, which can be beneficial to achieving load consistency of the data signal. This example can reduce the wiring differences within the lower left frame and the lower right frame, which is beneficial to reducing the transmission load differences of the same signal within the lower left frame and the lower right frame. The remaining description of this example can refer to the description of the aforementioned embodiment, so it will not be repeated here.

[0149] Fig.10 Another partial schematic diagram of the first border area of ​​at least one embodiment of the utility model. Fig.11 for Fig.10 Schematic diagram of a partial enlargement of region S3 in FIG. Fig.10 and Fig.11 As shown, the first distance L1 may be greater than the second distance L2, and the first center line O2 may be located on one side of the first center line O1 in the second direction X. The left and right lines of the third center line O3 in the bending area B12 may be arranged roughly symmetrically. The third center line O3 may be located between the first center line O1 and the second center line O2. The fourth center line O4 may coincide with the third center line O3.

[0150] In some examples, a ratio of the second edge distance b to the first edge distance a may be greater than 1. In other words, the second edge distance b may be greater than the first edge distance a.

[0151] In some examples, the length of the first data extension segment 21-1a of at least one first data fan-out line 21a near the first center line O1 may be less than the length of the first data extension line 21-1b of at least one first data fan-out line 21b near the first center line O1. The length of the second data extension segment 21-2a of at least one first data fan-out line 21a near the first center line O1 may be greater than the length of the second data extension line 21-2b of at least one first data fan-out line 21b near the first center line O1.

[0152] In this example, the routing of the bending area B12 can be arranged roughly symmetrically about the third center line O3. By adjusting the first edge distance a and the second edge distance b (for example, the second edge distance b is greater than the first edge distance a), the third center line O3 can be located between the second center line O2 and the first center line O1 (or overlap with the first center line O1), reducing the load difference between the first data fan-out lines in the first sub-area B11, thereby facilitating the compensation of the data signal, which can be beneficial to achieving load consistency of the data signal. This example can reduce the wiring differences within the lower left frame and the lower right frame, which is beneficial to reducing the transmission load differences of the same signal within the lower left frame and the lower right frame. The remaining description of this example can refer to the description of the aforementioned embodiment, so it will not be repeated here.

[0153] Fig.12 Another partial schematic diagram of the first border area of ​​at least one embodiment of the utility model. Fig.13 for Fig.12 Schematic diagram of a partial enlargement of region S4 in FIG. Fig.12 and Fig.13 As shown, the first center line O1 may be located on one side of the second center line O2 in the second direction X. The multiple signal bending lines in the bending area B12 may include: four groups of data bending lines (for example, including a first group of data bending lines 311, a second group of data bending lines 312, a third group of data bending lines 313, and a fourth group of data bending lines 314), five groups of first power bending lines (for example, including a first group of first power bending lines 321, a second group of first power bending lines 322, a third group of first power bending lines 323, a fourth group of first power bending lines 324, and a fifth group of first power bending lines 325), two groups of second power bending lines (for example, including a first group of second power bending lines 331, a second group of second power bending lines 332), and two groups of control bending lines (for example, including a first group of control bending lines 341 and a second group of control bending lines 342). The first group of control bending lines 342, the first group of second power bending lines 331, the fourth group of first power bending lines 324, the third group of data bending lines 313, the second group of first power bending lines 322, the first group of data bending lines 311, the first group of first power bending lines 321, the second group of data bending lines 313, the third group of first power bending lines 323, the fourth group of data bending lines 314, the fifth group of first power bending lines 325, the second group of second power bending lines 332 and the second group of control bending lines 342 can be arranged in sequence along the second direction X.

[0154] In some examples, the total length of the first group of first power bending lines 321 along the second direction X may be less than Figure 8The total length of the first group of first power meander lines in the illustrated embodiment along the second direction X. For example, the total length along the second direction X may be reduced by reducing the number of first power meander lines in the first group of first power meander lines, or the total length along the second direction X may be reduced by reducing the spacing between adjacent first power meander lines in the first group of first power meander lines, or the length along the second direction X may be reduced by reducing the line width and spacing of the first power meander lines in the first group of first power meander lines. This embodiment is not limited to this.

[0155] In some examples, the plurality of signal bending lines in the bending region may have a fourth center line O4 extending along the first direction Y, and the plurality of signal bending lines may be symmetrically arranged about the fourth center line O4. The fourth center line O4 may coincide with the third center line O3, and the third center line O3 may coincide with the first center line O1. The plurality of first data fan-out lines in the first sub-region B11 may be symmetrically arranged about the first center line O1, for example, the plurality of first data fan-out lines 21a and the plurality of first data fan-out lines 21b may be symmetrically arranged about the first center line O1. The first group of data lead lines 411 and the second group of data lead lines 412 may be symmetrically arranged about the first center line O1.

[0156] In this example, by moving the routing in the bending area B12 as a whole along the second direction X and reducing the length of the first group of first power bending lines along the second direction, combined with the adjustment of the first edge distance a and the second edge distance b, the third center line O3 can be made to coincide with the first center line O1. In this example, the plurality of first data fan-out lines in the first sub-area B11 can be made roughly symmetrical about the first center line O1, and the consistency of the data signal load in the first sub-area can be ensured. In this example, a group of signal bending lines are symmetrically arranged about the first center line O1, which can help reduce the wiring differences in the lower left frame and the lower right frame, and help reduce the transmission load differences of the same signal in the lower left frame and the lower right frame. The rest of the description of this example can refer to the description of the aforementioned embodiment, so it will not be repeated here.

[0157] Fig.14 FIG. 1 is another partial schematic diagram of the first border area of ​​at least one embodiment of the utility model. In some examples, such as Fig.14As shown, the first center line O1 may be located on one side of the second center line O2 in the second direction X. The multiple signal bending lines in the bending area B12 may include: four groups of data bending lines (for example, including a first group of data bending lines 311, a second group of data bending lines 312, a third group of data bending lines 313, and a fourth group of data bending lines 314), five groups of first power bending lines (for example, including a first group of first power bending lines 321, a second group of first power bending lines 322, a third group of first power bending lines 323, a fourth group of first power bending lines 324, and a fifth group of first power bending lines 325), two groups of second power bending lines (for example, including a first group of second power bending lines 331, a second group of second power bending lines 332), and two groups of control bending lines (for example, including a first group of control bending lines 341 and a second group of control bending lines 342). The first group of control bending lines 342, the first group of second power bending lines 331, the fourth group of first power bending lines 324, the third group of data bending lines 313, the second group of first power bending lines 322, the first group of data bending lines 311, the first group of first power bending lines 321, the second group of data bending lines 313, the third group of first power bending lines 323, the fourth group of data bending lines 314, the fifth group of first power bending lines 325, the second group of second power bending lines 332 and the second group of control bending lines 342 can be arranged in sequence along the second direction X.

[0158] In some examples, the length of the orthographic projection of the fourth group of first power bend lines 324 on the substrate along the second direction X may be greater than the length of the orthographic projection of the first group of first power bend lines 321 on the substrate along the second direction X; the length of the orthographic projection of the first group of first power bend lines 321 on the substrate along the second direction X may be greater than the length of the orthographic projection of the second group of first power bend lines 322, the third group of first power bend lines 323, and the fifth group of first power bend lines 325 on the substrate along the second direction X.

[0159] In some examples, the total length of the fourth group of first power bending lines 324 along the second direction X can be increased by at least one of the following methods: increasing the number of first power bending lines in the fourth group of first power bending lines 324, increasing the spacing length between adjacent first power bending lines in the fourth group of first power bending lines 324, and increasing the line width of the first power bending lines in the fourth group of first power inner bending lines 324. However, this embodiment is not limited to this.

[0160] In this example, the multiple power bending lines in the bending area may include: multiple first power bending lines and multiple second power bending lines. The first group of power bending lines located on one side of the third center line O3 may include: the second group of first power bending lines 322, the fourth group of first power bending lines 324, half of the first group of first power bending lines 321, and the first group of second power bending lines 331; the second group of power bending lines located on the other side of the third center line O3 may include: the third group of first power bending lines 323, the fifth group of first power bending lines 325, half of the first group of first power bending lines 321, and the second group of second power bending lines 332. By increasing the length of the fourth group of first power bending lines 324 along the second direction X, the length of the first group of power bending lines along the second direction X is made greater than the length of the second group of power bending lines along the second direction X. However, this embodiment is not limited to this. In some other examples, the length of the first group of second power meandering lines 331 along the second direction X may be increased so that the length of the first group of second power meandering lines along the second direction X is greater than the length of the second group of power meandering lines along the second direction X.

[0161] In some examples, a plurality of data bending lines among the plurality of signal bending lines may be symmetrically arranged about the third center line O3, the plurality of signal bending lines may have a fourth center line O4 extending along the first direction Y, the fourth center line O4 may be located on a side of the third center line O3 close to the second center line O2, for example, the fourth center line O4 may coincide with the second center line O2. The plurality of signal bending lines may be asymmetrically arranged about the fourth center line O4.

[0162] In some examples, the third center line O3 is a symmetry line of the plurality of data bending lines. The third center line O3 may coincide with the first center line O1. For example, the first group of data bending lines 311 and the second group of data bending lines 312 may be substantially symmetrical with respect to the first center line O1, and the third group of data bending lines 313 and the fourth group of data bending lines 314 may be substantially symmetrical with respect to the first center line O1. In this way, the plurality of data fan-out lines in the first sub-region B11 may be symmetrically arranged with respect to the first center line O1, thereby reducing the load difference between the first data fan-out lines on both sides of the first center line O1 in the first sub-region B11, which is conducive to achieving load consistency of the data signal.

[0163] In some examples, the first group of control bending lines 341 and the second group of control bending lines 342 are not symmetrically arranged about the third center line O3, and the first group of second power bending lines 331 and the second group of second power bending lines 332 are not symmetrically arranged about the third center line O3. For example, the first group of control bending lines 341 and the second group of control bending lines 342 can be symmetrically arranged about the second center line O2, and the first group of second power bending lines 331 and the second group of second power bending lines 332 can be symmetrically arranged about the second center line O2. The ratio of the first edge distance a to the second edge distance b can be 0.9 to 1.1, for example, the first edge distance a and the second edge distance b can be substantially the same. In this way, it can be beneficial to improve the uniformity of the routing in the bending area and ensure the bending effect.

[0164] In this example, by increasing the length of the fourth group of first power bending lines 324 along the second direction X, multiple groups of data bending lines can be symmetrically arranged about the first center line O1, which can be beneficial to achieving load consistency of data signals, and can make the first edge distance and the second edge distance substantially the same, which can reduce the wiring differences in the lower left frame and the lower right frame, and is beneficial to reducing the transmission load differences of the same signal in the lower left frame and the lower right frame. The rest of the description of this example can refer to the description of the aforementioned embodiment, so it will not be repeated here.

[0165] In other examples, the plurality of data bending lines can be symmetrically arranged about the first center line and the first edge distance and the second edge distance can be substantially the same by increasing the length of the fourth group of first power bending lines and the first group of second power bending lines along the second direction.

[0166] In other examples, the multiple groups of data bending lines can be symmetrically arranged about the first center line and the first edge distance and the second edge distance can be substantially the same by reducing the length of at least one of the fifth group of first power bending lines and the second group of second power bending lines along the second direction.

[0167] In other examples, by increasing the length of at least one of the fourth group of first power bend lines and the first group of second power bend lines along the second direction, and by reducing the length of at least one of the fifth group of first power bend lines and the second group of second power bend lines along the second direction, multiple groups of data bend lines can be symmetrically arranged about the first center line, and the first edge distance and the second edge distance can be approximately the same.

[0168] Fig.15 is another schematic diagram of a display substrate of at least one embodiment of the present invention. Fig.15As shown, the display area AA may be provided with a plurality of data lines DL and a plurality of data transfer lines 25. At least one data line DL may be connected to the first data fan-out line of the first sub-area B11 through the data transfer line 25. The data transfer line 25 may include a first transfer section 251 extending along the second direction X and a second transfer section 252 extending along the first direction Y. The first transfer section 251 may be connected to the data line DL and the second transfer section 252, and the second transfer section 252 may be connected to the first data fan-out line. The second transfer section 252 may be located on a side of the connected data line DL away from the edge of the display substrate. In some examples, the first transfer section 251 and the second transfer section 252 may be located in the third source-drain metal layer, and the data line DL may be located in the second source-drain metal layer. However, this embodiment is not limited to this. The structural description of the first frame area of ​​the display substrate of this example can refer to the description of the aforementioned embodiment, so it will not be repeated here.

[0169] This embodiment also provides a display substrate, comprising: a display area and a first frame area located on one side of the display area along a first direction. The first frame area comprises: a bending area, a first sub-area located between the bending area and the display area; the display area has a first center line extending along the first direction, the first frame area has a second center line extending along the first direction, and the distance between the first center line and the second center line is greater than 0. The display substrate comprises: a substrate, a plurality of sub-pixels and a plurality of data lines arranged on one side of the substrate and located in the display area, a plurality of first data fan-out lines located in the first sub-area, and a plurality of signal bending lines located in the bending area. The plurality of data lines are electrically connected to the plurality of sub-pixels, and the plurality of data lines are configured to provide data signals to the plurality of sub-pixels. The plurality of first data fan-out lines are connected to the plurality of data lines. The plurality of signal bending lines are located in the same conductive layer. The plurality of signal bending lines at least comprise: a plurality of data bending lines, the plurality of data bending lines are connected to the plurality of first data fan-out lines, and the plurality of data bending lines are symmetrically arranged about the third center line. The plurality of signal bending lines have a fourth center line extending along the first direction, the fourth center line coincides with the third center line, or is located on a side of the third center line close to the second center line. The first center line, the second center line, the third center line and the fourth center line may extend in the same direction.

[0170] In this embodiment, in view of the situation that the first center line of the display area and the second center line of the first frame area are not on the same straight line, the multiple data bending lines in the bending area are symmetrically arranged according to the third center line, and the fourth center line of the multiple signal bending lines in the bending area coincides with the third center line, or is located on the side of the third center line close to the second center line. This can ensure the density of the data bending lines in the bending area and the consistency of the film layer, facilitate the bending effect, and improve the problem caused by the signal routing differentiation caused by the asymmetric shape of the display substrate.

[0171] In some exemplary embodiments, the plurality of signal bending lines may be symmetrically arranged about a fourth center line; the third center line and the fourth center line coincide with the second center line. The first frame area has a first frame edge and a second frame edge extending along a first direction, the first frame edge and the second frame edge are located on both sides of the signal bending line of the bending area along a second direction, and the second direction intersects with the first direction. For example, the second direction may be perpendicular to the first direction. The minimum distance between the signal bending line of the bending area and the first frame edge is the first edge distance, the minimum distance between the signal bending line of the bending area and the second frame edge is the second edge distance, and the ratio of the first edge distance to the second edge distance is 0.9 to 1.1. For example, the first edge distance may be equal to the second edge distance. This example can ensure the consistency of the distance between the routing of the bending area and the two side edges of the display panel, which is beneficial to the routing arrangement of the bending area and to ensure the bending effect.

[0172] In some exemplary embodiments, the plurality of signal bend lines may be symmetrically arranged about the fourth center line. The third center line coincides with the fourth center line and is located between the first center line and the second center line; or, the third center line and the fourth center line coincide with the first center line. The first frame area has a first frame edge and a second frame edge extending in a first direction, and the first frame edge and the second frame edge are located on both sides of the signal bend line of the bend area along the second direction. The minimum distance between the signal bend line of the bend area and the first frame edge is the first edge distance, the minimum distance between the signal bend line of the bend area and the second frame edge is the second edge distance, the ratio of the first edge distance to the second edge distance is greater than 1, or the ratio of the second edge distance to the first edge distance is greater than 1. In other words, the first edge distance is different from the second edge distance. This example is beneficial to ensure the symmetrical arrangement of the routing of the bend area by adjusting the difference between the first edge distance and the second edge distance, thereby reducing the difference between the signals in the first frame area.

[0173] In some exemplary embodiments, a plurality of signal bending lines may be asymmetrically arranged about a fourth center line, the fourth center line may coincide with the second center line, and the third center line may coincide with the first center line. The first frame area may have a first frame edge and a second frame edge extending along a first direction, and the first frame edge and the second frame edge are located on both sides of the signal bending line of the bending area along the second direction. The minimum distance between the signal bending line of the bending area and the first frame edge is the first edge distance, the minimum distance between the signal bending line of the bending area and the second frame edge is the second edge distance, and the ratio of the first edge distance to the second edge distance is 0.9 to 1.1. For example, the first edge distance may be equal to the second edge distance. This example can ensure the consistency of the distance between the routing of the bending area and the two side edges of the display panel, which is beneficial to the routing arrangement of the bending area and to ensure the bending effect.
