DETAILED DESCRIPTION

[0108] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0109] In this article, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also include elements inherent to such process, method, article or equipment. In the absence of further restrictions, the elements defined by the statement "comprising a ..." do not exclude the presence of other identical elements in the process, method, article or equipment comprising the elements. The term "two or more" includes two or more than two cases.

[0110] Currently, metal etching processes can be performed on the driving substrate of the organic layer. However, due to the poor etching resistance of the organic layer, the organic layer will be affected by the gas and form a rough surface, resulting in metal residue on the touch signal line. The residual metal will cause a short circuit between adjacent and different touch signal lines, affecting the signal transmission of the display panel.

[0111] In view of this, embodiments of the present disclosure provide a display panel and a display device, which can improve the flexibility of the display panel.

[0112] In the first aspect of the present disclosure, Figure 1 A schematic top view of a display panel provided in an embodiment of the present disclosure, with reference to Figure 1 The present disclosure provides a display panel including a drive substrate, at least two touch electrode layers, and a first organic layer. The drive substrate includes a base layer and a drive layer, wherein the drive layer is disposed on one side of the base layer, the at least two touch electrode layers are disposed on a side of the drive layer away from the base layer, the touch electrode layers are provided with touch electrodes, and the first organic layer is disposed between the at least two touch electrode layers.

[0113] Illustratively, the first organic layer disposed between the touch electrode layers can improve the flexibility of the display panel.

[0114] In some examples, reference Figure 1The driving layer includes a display area 100 and a non-display area 200. The non-display area 200 at least partially surrounds the display area 100. The non-display area 200 includes a first area 210, a second area 220, and a third area 230. The second area 220 is located between the first area 210 and the third area 230, and the first area 210 is located between the second area 220 and the display area 100. The third area 230 is provided with binding pins 231. The display panel corresponding to the second area 220 is used for bending. The third area 230 is provided with touch signal lines. The touch signal lines are provided in at least one touch electrode layer. The touch signal lines are electrically connected to some of the binding pins 231, and the touch signal lines are electrically connected to the touch electrodes.

[0115] Exemplary, reference Figure 1 The display panel of the second area 220 is bent, and the display panel corresponding to the third area 230 can be set on the side of the display panel of the display area away from the display side, which can increase the display screen ratio.

[0116] For example, a complete touch signal line can run through the first, second, and third regions. The touch electrode layers in the first region can be arranged in parallel to reduce the resistance of the signal line. The first organic layer can be arranged between adjacent touch electrode layers. The touch electrode layer in the second region can be arranged on the same layer as the electrode layer in the display region. For example, part of the touch electrode layer can be arranged on the same layer as the source and drain electrode layer. The binding pins in the third region can be bound to a driver chip or a flexible circuit board. If the binding pins are bound to the flexible circuit board, the flexible circuit board must be bound to the driver chip.

[0117] In some examples, an orthographic projection of the first organic layer on the substrate layer overlaps with an orthographic projection of a portion of the touch signal line on the substrate layer.

[0118] Figure 2 A schematic partial structural diagram of a display area of another display panel provided in an embodiment of the present disclosure. Figure 2Regarding the display area 100, the drive substrate 300 includes a base layer 310 and a drive layer 320. The drive layer 320 is disposed on one side of the base layer 310. The first inorganic layer 800 is disposed between the two touch electrode layers, namely, between the first touch electrode layer 410 and the second touch electrode layer 420. The first organic layer 500 can be disposed between the two touch electrode layers for the same touch signal line. During the etching process of the upper touch electrode layer, due to the poor etching resistance of the first organic layer 500, the first organic layer 500 is affected by the gas and forms a rough surface, resulting in metal residue on the touch signal line. The residual metal can easily cause short circuits between adjacent touch signal lines. The first organic layer 500 is then etched through an etching process, disconnecting the first organic layers 500 corresponding to the touch signal lines on the same layer. Adjacent touch signal lines cannot be electrically connected through the surface of the first organic layer 500, thereby improving the signal transmission efficiency of the display panel.

[0119] The present disclosure improves the flexibility of the display panel by providing a first organic layer, thereby improving the display panel's performance such as impact resistance, foldability, and extrusion resistance.

[0120] In some embodiments, the touch signal line includes a first touch signal line and a second touch signal line, and the first touch signal line and the second touch signal line are respectively disposed in different touch electrode layers.

[0121] In some examples, the touch electrode layer may include a first touch electrode layer and a second touch electrode layer, the drive substrate includes a drive layer and a substrate layer, the drive layer is disposed on one side of the substrate layer, the first touch electrode layer and the second touch electrode layer are disposed on a side of the drive layer away from the substrate layer, the first touch electrode layer is disposed between the drive layer and the second touch electrode layer, and the first organic layer is disposed between the first touch electrode layer and the second touch electrode layer. The touch signal line includes a first touch signal line and a second touch signal line, the first touch signal line may be disposed in the first touch electrode layer, and the second touch signal line may be disposed in the second touch electrode layer.

[0122] For example, the touch signal lines can be provided with only the first touch signal line, that is, the touch signal lines are provided on a single first touch electrode layer. During the deposition of the touch signal lines, the flatness of the underlying drive layer can be ensured. Because the touch signal lines are made of metal, which is susceptible to corrosion by water and oxygen, using a single layer of touch signal lines can eliminate a layer of metal, avoid interference between different touch signal lines, and thus improve the reliability of the display panel.

[0123] For example, the touch signal line may be provided as only the second touch signal line, that is, the touch signal line is provided on a single second touch electrode layer. After etching the first organic layer, the problem of short circuit between the second touch signal lines caused by residual metal can be avoided.

[0124] For example, a touch signal line can be formed by connecting a first touch signal line and a second touch signal line in series. For example, a segmented first touch signal line and a segmented second touch signal line can be connected to form a single touch signal line. The electrical connection between the first touch signal line and the second touch signal line is achieved by drilling a hole in the first organic layer. For the same touch signal line, the first touch signal line can be connected in series with the second touch signal line. The etched first organic layer can also prevent short circuits between adjacent touch signal lines.

[0125] In some examples, an orthographic projection of the first organic layer on the substrate layer overlaps with an orthographic projection of at least a portion of the first touch signal line on the substrate layer.

[0126] Exemplarily, the first touch signal line can be arranged on the first touch electrode layer, and the first organic layer can be arranged on the side of the first touch electrode layer away from the driving layer. The first organic layer corresponding to the third area is etched using an etching process, so that the first organic layer partially covers the first touch signal line or the first organic layer covers the first touch signal line.

[0127] In some examples, an orthographic projection of the first organic layer on the substrate layer overlaps with an orthographic projection of at least a portion of the second touch signal line on the substrate layer.

[0128] Exemplarily, the second touch signal line can be arranged in the second touch electrode layer, and the first organic layer can be arranged between the second touch electrode layer and the first touch electrode layer. The first organic layer corresponding to the third area is etched using an etching process, so that the second touch signal line partially covers the first organic layer or the second touch signal line covers the first organic layer.

[0129] In some examples, the orthographic projection of the first organic layer on the substrate layer overlaps with the orthographic projection of at least part of the first touch signal line on the substrate layer, and the orthographic projection of the first organic layer on the substrate layer overlaps with the orthographic projection of at least part of the second touch signal line on the substrate layer.

[0130] Illustratively, the first touch signal line may be electrically connected to the second touch signal line through a via, the first organic layer covers the first touch signal line, and the second touch signal line covers a portion of the first organic layer to achieve overlap of orthographic projections.

[0131] In some examples, the first touch signal line is set in the first touch electrode layer, the second touch signal line is set in the second touch electrode layer, the orthographic projection of the first touch signal line on the substrate layer overlaps with the orthographic projection of the first organic layer on the substrate layer, and the orthographic projection of the second touch signal line on the substrate layer does not overlap with the orthographic projection of the first organic layer on the substrate layer.

[0132] Figure 3A schematic partial structural diagram of a display panel provided by an embodiment of the present disclosure. Exemplarily, referring to Figure 3 , for the third region 320, the first organic layer 500 can cover the first touch signal line 411, the second touch signal line 421 can be spaced apart from the first organic layer 500, and the spacing direction is the direction of the plane where the driving layer 320 is located. The second touch signal line 421 is also spaced apart from the first touch signal line 411. The first touch signal line 411 and the second touch signal line 421 can respectively transmit odd and even signals. The alternating arrangement of the first touch signal line 411 and the signal line 421 can increase the spacing between the touch signal lines in the same layer, thereby reducing the risk of short circuit between the touch signal lines. In addition, it can also weaken the interference between adjacent touch signal lines.

[0133] In some examples, the routing space in the third region is relatively large, and the equal resistance of different touch signal lines can be achieved by adjusting the line width of the touch signal lines.

Exemplarily, referring to Figure 4 , for the third region 230, the width of the first touch signal line 411 in the first direction is the first dimension a, the width of the second touch signal line 421 in the first direction is the second dimension b, and the width of the second touch signal line 421 is greater than the width of the first touch signal line 411, that is, b > a. The region corresponding to the second touch signal line 421 is the etching region of the first organic layer 500, and the spacing between the second touch signal line 421 and the first organic layer 500 is the third dimension c, and the size of c can be adjusted according to the actual situation.

[0135] In some examples, 0 < a < b ≤ 50 um, 0 < b - a ≤ 10 um, so as to better utilize the routing space in the third region.

[0136] In some examples, the same touch signal line includes the first touch signal or the second touch signal line, and the first touch signal line and the second touch signal line are alternately arranged in the first direction X, where the first direction intersects the second direction, and the second direction is the length direction of the touch signal line.

[0137] Exemplarily, referring to Figure 3The first touch signal lines 411 and the second touch signal lines 421 are spaced apart in the first direction X. The second touch signal lines 421 can be spaced apart from the first organic layer 500 and can be coplanar with the first touch signal lines 411. The distance between the second touch signal lines 421 and the first organic layer 500 can prevent adjacent second touch signal lines 421 in the first direction X from being electrically connected through metal etching residues on the surface of the first organic layer 500 away from the substrate layer 310. Furthermore, the alternating arrangement of the touch signal lines increases the distance between the two second touch signal lines 421 in the first direction, making it difficult for the two second touch signal lines 421 to be electrically connected through the metal etching residues on the upper surface of the first organic layer 500. The first direction X can be parallel to the plane of the drive layer 320.

[0138] In some examples, the first organic layer includes a first hollow, the orthographic projection of the first hollow on the substrate layer falls within the spacing area between adjacent first touch signal lines, and the orthographic projection of the second touch signal line on the substrate layer falls within the orthographic projection of the first hollow on the substrate layer.

[0139] Exemplary, reference Figure 3 The first organic layer 500 can be arranged on the side of the first touch signal line 411 away from the driving layer 320, and a first hollow 510 is formed on the first organic layer 500 through an etching process. The second touch signal line 421 is arranged on the side of the first organic layer 500 away from the driving layer 320, and the second touch signal line 421 corresponding to the first hollow 510 is retained through an etching process. The size of the first hollow 510 in the first direction X is larger than the size of the second touch signal line 421 in the first direction X. The orthographic projection of the second touch signal line 41 on the drive layer 320 falls within the orthographic projection of the first hollow 510 on the drive layer 320. The first hollow 510 can form a spacing space between adjacent touch signal lines. During the etching process of the first organic layer 500, the residual metal on the surface of the first organic layer 500 will not conduct the adjacent second touch signal line 421 through the first hollow 510. In other words, during the etching process of the second touch signal line 421, part of the second touch signal line 421 is avoided from remaining on the surface of the first organic layer 500 away from the drive layer 320, thereby avoiding the occurrence of electrical connection between adjacent touch signal lines.

[0140] Exemplary, reference Figure 4 The first hollow 510 of the first organic layer 500 is used to form the second touch signal line 421 , and the distance between the wall surface of the first organic layer 500 corresponding to the first hollow 510 and the second touch signal line 421 may be a first distance c.

[0141] In some examples, the same touch signal line includes a first touch signal line or a second touch signal line, and the first touch signal line and the second touch signal line are alternately arranged in a first direction. The first organic layer covers the first touch signal line, and adjacent second touch signal lines are separated from the first touch signal lines by the first organic layer in a third direction, where the third direction is perpendicular to the plane where the drive layer is located.

[0142] Figure 5 A schematic partial structural diagram of another display panel provided in an embodiment of the present disclosure. Figure 5 In the third region 230, the first organic layer 500 can be retained, and the second touch signal lines 421 are formed on a side of the first organic layer 500 away from the first touch signal lines 411. Adjacent first touch signal lines 411 are spaced apart in the first direction X, and the second touch signal lines 421 correspond to the spaces between adjacent first touch signal lines 411, thereby increasing the distance between the second touch signal lines 421 in the first direction. After etching the second touch signal lines 421, although metal may remain on the surface of the first organic layer 500, the increased distance makes it difficult for adjacent second touch signal lines 421 in the first direction to be electrically connected through the surface of the first organic layer 500.

[0143] Figure 6 A schematic top view of a display panel is provided for an embodiment of the present disclosure. Figure 6 Can correspond to Figure 5 For example, refer to Figure 6 The orthographic projection of the second touch signal line 421 on the driving layer 320 does not overlap with the orthographic projection of the first touch signal line 411 on the driving layer 320. Since there is no need to etch the first organic layer 500, Figure 6 The distance between the first touch signal line 411 and the second touch signal line 421 is less than Figure 4 In addition, the distance between the second touch signal lines 421 is increased, which can reduce the risk of short circuit caused by etching residue of the second touch electrode layer between adjacent second touch signal lines.

[0144] In some examples, the first distance c is less than or equal to 10 μm.

[0145] In some examples, the first organic layer located in the first area includes a first via, the same touch signal line includes a first touch signal line and a second touch signal line, the first touch signal line and the second touch signal line are arranged alternately in a first direction, and the first touch signal line and the second touch signal line of the same touch signal line are electrically connected through the first via.

[0146] Figure 7A schematic top view of a display panel provided in an embodiment of the present disclosure. Figure 7 The first touch signal line 411 can be set in the first touch electrode layer 410, and the second touch signal line 421 can be set in the second touch electrode layer 420. The first touch signal line 411 and the second touch signal line 421 are set in different layers, and for the same touch signal line, the first touch signal line 411 can be electrically connected to the second touch signal line 421 through the first via 450.

[0147] Exemplary, reference Figure 7 For the same touch signal line, the first touch signal line 411 is connected to the second touch signal line 421 through the first via 450. The length of the first touch signal line 411 in the second direction Y is L1, and the length of the second touch signal line 421 in the second direction Y is L2. Figure 7 As shown, L1>L2, thereby increasing the space of the second touch electrode layer 420 and reducing the short circuit risk of the second touch signal line 421 caused by incomplete etching.

[0148] In some examples, the length of the first touch signal line is greater than the length of the second touch signal line, and the first touch signal line and the second touch signal line have different widths.

The third direction is from the substrate layer toward the drive layer. The first organic layer can be etched using the aforementioned technical solution to prevent adjacent touch signal lines from conducting through the surface of the first organic layer.

[0165] Exemplarily, the touch leads are used for electrical connection between the touch signal lines and the display area.

[0166] In some examples, the touch electrode layer includes a stacked structure of multiple metal layers to form corresponding touch signal lines.

[0178] In the second aspect of the present disclosure, Figure 13 A schematic partial structural diagram of a display area of a display panel provided by an embodiment of the present disclosure. Figure 13, provides another display panel, including a driving substrate 300, at least two touch electrode layers and a first organic layer 500. The driving substrate 300 includes a substrate layer 310 and a driving layer 320, and the driving layer 320 is arranged on one side of the substrate layer 310. The at least two touch electrode layers are arranged on the side of the driving layer 320 away from the substrate layer 30, and the touch electrode layers are provided with touch electrodes. The first organic layer 500 is arranged between the at least two touch electrode layers. The driving layer 320 includes a display area and a non-display area, and the non-display area 200 at least partially surrounds the display area. The non-display area includes a first area, a second area and a third area. The second area is located between the first area and the third area. The third area is provided with binding pins. The display panel corresponding to the second area is used for bending. The third area is provided with touch signal lines. The touch signal lines are arranged in at least one touch electrode layer, and the touch signal lines are electrically connected to some binding pins, and the touch signal lines are electrically connected to the touch electrodes. The orthographic projection of the first organic layer on the substrate layer does not overlap with the orthographic projection of the touch signal line on the substrate layer.

[0179] Exemplary, reference Figure 13 The first organic layer 500 corresponding to the third region 230 can be removed by an etching process, so that at least two touch electrodes in the same touch signal line are arranged in parallel to reduce the resistance of the touch signal line and improve the signal transmission efficiency of the display panel.

[0180] For example, all the first organic layers in the non-display area may be removed, the first organic layer in the third area may be removed alone, or the first organic layers in the first and third areas may be removed alone.

[0181] In some examples, the at least two touch electrode layers include a first touch electrode layer and a second touch electrode layer, the first touch electrode layer is disposed between the drive layer and the first organic layer, and the first organic layer is disposed between the first touch electrode layer and the second touch electrode layer;

[0182] The touch signal line includes a first conductive structure and a second conductive structure.

In the third area of the non-display region, a surface of the first conductive structure facing away from the drive layer is connected to a surface of the second conductive structure facing closer to the drive layer. The first and second conductive structures can be overlapped to form a touch signal line. No dielectric layer can be provided between the first and second conductive structures. This reduces the resistance of the touch signal line and prevents short circuits between adjacent touch signal lines caused by dielectric conduction.

[0183] In some examples, a size of the first conductive structure in the first direction is smaller than a size of the second conductive structure in the first direction, the first direction intersects with the second direction, and the second direction is the length direction of the touch signal line.

[0184] Figure 14 A schematic top view of another display panel provided in an embodiment of the present disclosure, Figure 14 Can correspond to Figure 13 For example, refer to Figure 14 , the size of the first conductive structure 430 in the first direction X can be a first size a, and the size of the second conductive structure 440 in the first direction X can be a second size b. In the direction of the plane where the driving layer 320 is located, that is, in the first direction X, the size of the first conductive structure 430 is smaller than the size of the second conductive structure 440, that is, a <b,。

[0185] In some examples, a size of the second conductive structure in the first direction is a second size, the second size is larger than the first size, and a difference between the second size and the first size is less than or equal to 10 μm.

[0186] In some examples, the at least two touch electrode layers include a first touch electrode layer and a second touch electrode layer, the first touch electrode layer is disposed between the drive layer and the first organic layer, and the first organic layer is disposed between the first touch electrode layer and the second touch electrode layer.

[0187] In some examples, the touch signal lines include a first touch signal line and a second touch signal line. The first touch signal line and the second touch signal line are connected in a third direction, which is perpendicular to the plane of the drive layer. The first touch signal line is provided in the first touch electrode layer, and the second touch signal line is provided in the second touch electrode layer. In the third region, the second touch signal line can overlap the first touch signal line and be provided in parallel with the first touch signal line. Furthermore, due to the etching process area of the first organic layer, adjacent second touch signal lines are not electrically connected, thereby improving the signal transmission efficiency of the display panel.

[0188] Exemplary, reference Figure 13 The first touch signal line 411 can be electrically connected to the first conductive structure 430, the second touch signal line 41 can be electrically connected to the second conductive structure 440, the second touch signal line 421 is arranged on the side of the first touch signal line 411 away from the driving layer 320, and the second touch signal line 421 can cover the first touch signal line 411.

[0189] In some examples, the touch signal line includes a second touch signal line, and the second touch signal line is disposed in the second touch electrode layer.

[0190] Figure 15 A schematic partial structural diagram of another display panel provided in an embodiment of the present disclosure. Figure 15The first organic layer 500 corresponding to the non-display area 200 can be removed by etching, and the second touch signal line 421 is disposed on one side of the driving layer 320 .

[0191] In some examples, the display panel further includes an encapsulation layer, a second organic layer, a third organic layer, and a first inorganic layer. The encapsulation layer is disposed between the drive layer and the touch electrode layer, the second organic layer is disposed on a side of the touch electrode layer farthest from the drive layer, away from the drive layer, the third organic layer is disposed between the touch electrode layer and the encapsulation layer, and the first inorganic layer is disposed between the third organic layer and the encapsulation layer, wherein an orthographic projection of the third organic layer on the substrate layer does not overlap with an orthographic projection of the touch signal line on the substrate layer.

[0192] Figure 16 A schematic partial structural diagram of a display panel provided in an embodiment of the present disclosure. Figure 16 The first organic layer 500 and the third organic layer 700 corresponding to the non-display area 200 can be removed through an etching process. The film layers corresponding to the third area 230 of the non-display area 200 can be the first inorganic layer 800, the first touch signal line 411, the second touch signal line 421, and the second organic layer 600 in the third direction Z. The third direction Z is the direction from the substrate layer 310 to the drive layer 320.

[0193] Exemplarily, the encapsulation layer may include two inorganic layers and one organic layer, the organic layer is disposed between the two inorganic layers, and a light-emitting device may further be included between the encapsulation layer and the driving layer.

[0194] In some examples, the display panel further includes an encapsulation layer, a second organic layer, a third organic layer, and a first inorganic layer. The encapsulation layer is disposed between the drive layer and the touch electrode layer, the second organic layer is disposed on a side of the touch electrode layer farthest from the drive layer, away from the drive layer, the third organic layer is disposed between the touch electrode layer and the encapsulation layer, and the first inorganic layer is disposed between the third organic layer and the encapsulation layer, wherein an orthographic projection of the third organic layer on the substrate layer overlaps an orthographic projection of the touch signal line on the substrate layer.

Figure 17 The first organic layer 500 corresponding to the non-display area 200 can be removed through an etching process. The film layers corresponding to the third area 230 of the non-display area 200 can be the first inorganic layer 800, the third organic layer 900, the first touch signal line 411, the second touch signal line 421, and the second organic layer 600 in the third direction Z. The third direction Z is the direction from the substrate layer to the drive layer.

[0196] In some examples, only the first touch signal line may be provided as the touch signal line, that is, the touch signal line is provided on a single first touch electrode layer. When depositing the touch signal line, the flatness of the underlying substrate can be ensured. Furthermore, because the touch signal line is made of metal, which is susceptible to corrosion by water and oxygen, using a single layer of touch signal line can reduce the need for a metal layer, thereby avoiding interference between different touch signal lines and improving the reliability of the display panel.

[0197] For example, only the second touch signal line can be provided as a touch signal line, that is, the touch signal line is provided on a single second touch electrode layer. In the third region, no first organic layer can be provided between the second touch signal line and the first touch electrode layer. This reduces the metal layer required by the display panel, avoids interference between different touch signal lines, and improves the reliability of the display panel.

[0198] For example, the touch signal line can be formed by connecting a first touch signal line and a second touch signal line in series. For example, a segmented first touch signal line and a segmented second touch signal line can be connected to form a single touch signal line. The electrical connection between the first touch signal line and the second touch signal line is achieved by drilling a hole in the first organic layer. In the third region, after the first organic layer is completely etched, adjacent touch signal lines will not short-circuit.

[0199] The third aspect of the present disclosure is Figure 18 A schematic partial structural diagram of another display panel provided in an embodiment of the present disclosure is shown in FIG. Figure 18 , provides another display panel, including a drive layer 300, a touch electrode layer, a third inorganic layer 900, and a third organic layer 700.

The third area is provided with binding pins, and the display panel corresponding to the second area is configured for bending. The first area is provided with touch signal lines, which are electrically connected to some of the binding pins and electrically connected to the touch electrodes.

[0201] In some examples, reference Figure 18, the orthographic projection of the third organic layer 700 on the driving layer 320 overlaps with the orthographic projection of the touch signal line on the driving layer 320 .

[0202] In some examples, reference Figure 18 The third inorganic layer 900 includes a second through hole 910, and the same touch signal line includes a first touch signal line 411 and a second touch signal line 421. The first touch signal line 411 is arranged on the first touch electrode layer 410, and the second touch electrode layer 421 is arranged on the second touch electrode layer 420. The first touch signal line 411 and the second touch signal line 421 are electrically connected through the second through hole 910.

[0204] In some examples, only the first touch signal line may be provided as the touch signal line, that is, the touch signal line is provided on a single first touch electrode layer. When depositing the touch signal line, the flatness of the underlying substrate can be ensured. Furthermore, because the touch signal line is made of metal, which is susceptible to corrosion by water and oxygen, using a single layer of touch signal line can reduce the need for a metal layer, thereby avoiding interference between different touch signal lines and improving the reliability of the display panel.

[0205] Exemplarily, the touch signal line may be provided as only the second touch signal line, that is, the touch signal line is provided on a single second touch electrode layer.

[0206] Exemplarily, the touch signal line can be formed by connecting a first touch signal line and a second touch signal line in series, for example, the segmented first touch signal line and the second touch signal line are connected into one touch signal line, and the electrical connection between the first touch signal line and the second touch signal line is achieved by drilling a hole in the first organic layer.

[0207] In some examples, the touch electrode layer includes a stacked structure of multiple metal layers to form corresponding touch signal lines.
