Detailed Implementation

[0109] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to 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.

[0110] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0111] Currently, metal etching can be performed on the driving substrate of organic layer. However, due to the poor etching resistance of organic layer, the organic layer will be affected by gas and form a rough surface, resulting in metal residue on the touch signal line. The residual metal will cause short circuits between adjacent and different touch signal lines, affecting the signal transmission of the display panel.

[0112] In view of this, the present disclosure provides a display panel and a display device that can improve the flexibility of the display panel.

[0113] A first aspect of this disclosure is illustrated in FIG1, which is a schematic top view of a display panel provided in an embodiment of this disclosure. Referring to FIG1, this disclosure provides a display panel including a driving substrate, at least two touch electrode layers, and a first organic layer. The driving substrate includes a substrate layer and a driving layer. The driving layer is disposed on one side of the substrate layer, and the at least two touch electrode layers are disposed on the side of the driving layer away from the substrate 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.

[0114] For example, a first organic layer disposed between the touch electrode layers can improve the flexibility of the display panel.

[0115] In some examples, referring to Figure 1, the 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 and 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 bonding 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 disposed on at least one touch electrode layer and are electrically connected to a portion of the bonding pins 231 and to the touch electrodes.

[0116] For example, referring to Figure 1, the bending of the display panel in the second region 220 allows the display panel corresponding to the third region 230 to be set on the side of the display panel away from the display side, thereby increasing the screen ratio.

[0117] For example, a complete touch signal line can run through the first region, the second region, and the third region. 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 disposed between adjacent touch electrode layers. The touch electrode layers in the second region can be disposed on the same layer as the electrode layers in the display area. For example, a portion of the touch electrode layers can be disposed on the same layer as the source and drain electrode layers. The bonding pins in the third region can be bonded to a driver chip or a flexible circuit board. If the bonding pins are bonded to a flexible circuit board, the flexible circuit board needs to be bonded to the driver chip.

[0118] In some examples, the orthographic projection of the first organic layer onto the substrate overlaps with the orthographic projection of a portion of the touch signal line onto the substrate.

[0119] Figure 2 is a schematic partial structural diagram of the display area of ​​another display panel provided in an embodiment of this disclosure. Referring to Figure 2, for the display area 100, the driving substrate 300 includes a substrate layer 310 and a driving layer 320. The driving layer 320 is disposed on one side of the substrate layer 310, and a first inorganic layer 800 is disposed between two touch electrode layers, specifically between the first touch electrode layer 410 and the second touch electrode layer 420. The first organic layer 500 can be disposed between two touch electrode layers on the same touch signal line. During the etching of the upper touch electrode layer, due to the poor etching resistance of the first organic layer 500, the first organic layer 500 will be affected by gas and form a rough surface, resulting in metal residue on the touch signal line. The residual metal will make it easy for short circuits to occur between adjacent touch signal lines. Therefore, the first organic layer 500 is etched using an etching process so that the first organic layers 500 corresponding to the touch signal lines on the same layer are disconnected. Adjacent touch signal lines cannot conduct through the surface of the first organic layer 500, thereby improving the signal transmission efficiency of the display panel.

[0120] This disclosure improves the flexibility of the display panel by setting a first organic layer, thereby enhancing the display panel's impact resistance, foldability, and compression resistance.

[0121] In some embodiments, the touch signal line includes a first touch signal line and a second touch signal line, wherein the first touch signal line and the second touch signal line are respectively disposed on different touch electrode layers.

[0122] In some examples, the touch electrode layer may include a first touch electrode layer and a second touch electrode layer. The driving substrate includes a driving layer and a substrate layer. The driving layer is disposed on one side of the substrate layer, and the first and second touch electrode layers are disposed on the side of the driving layer away from the substrate layer. The first touch electrode layer is disposed between the driving layer and the second touch electrode layer, and a first organic layer is disposed between the first and second touch electrode layers. The touch signal line includes a first touch signal line and a second touch signal line. The first touch signal line may be disposed on the first touch electrode layer, and the second touch signal line may be disposed on the second touch electrode layer.

[0123] For example, the touch signal line can consist of only a first touch signal line, meaning the touch signal line is disposed on a single first touch electrode layer. This ensures the flatness of the underlying driving layer during the deposition of the touch signal line. Because the touch signal line is made of metal, which is susceptible to corrosion from water and oxygen, using a single-layer touch signal line reduces the amount of metal required, avoiding interference between different touch signal lines and improving the reliability of the display panel.

[0124] For example, the touch signal lines can consist of only the second touch signal lines, meaning the touch signal lines are disposed on a single second touch electrode layer. By etching the first organic layer, the problem of short circuits between the second touch signal lines caused by residual metal can be avoided.

[0125] 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 instance, a segmented first touch signal line and a segmented second touch signal line can be connected to form a single touch signal line. Electrical connection between the first and second touch signal lines is achieved by drilling holes 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, and the etched first organic layer can also prevent short circuits between adjacent touch signal lines.

[0126] In some examples, the orthographic projection of the first organic layer onto the substrate overlaps with the orthographic projection of at least a portion of the first touch signal line onto the substrate.

[0127] For example, the first touch signal line can be disposed on the first touch electrode layer, and the first organic layer is disposed on the side of the first touch electrode layer away from the driving layer. By using an etching process to etch the first organic layer corresponding to the third region, the first organic layer can partially cover the first touch signal line or the first organic layer can wrap around the first touch signal line.

[0128] In some examples, the orthographic projection of the first organic layer onto the substrate overlaps with the orthographic projection of at least a portion of the second touch signal line onto the substrate.

[0129] For example, the second touch signal line can be disposed on the second touch electrode layer, and the first organic layer is disposed between the second touch electrode layer and the first touch electrode layer. By using an etching process to etch the first organic layer corresponding to the third region, the second touch signal line can partially cover the first organic layer or the second touch signal line can wrap around the first organic layer.

[0130] In some examples, the orthographic projection of the first organic layer on the substrate overlaps with the orthographic projection of at least a portion of the first touch signal line on the substrate, and the orthographic projection of the first organic layer on the substrate overlaps with the orthographic projection of at least a portion of the second touch signal line on the substrate.

[0131] For example, the first touch signal line can 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 an overlap of orthographic projection.

[0132] In some examples, the first touch signal line is disposed on the first touch electrode layer, and the second touch signal line is disposed on 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.

[0133] FIG. 3 is a schematic partial structural diagram of a display panel provided by an embodiment of the present disclosure. Exemplarily, referring to FIG. 3, for the third region 320, the first organic layer 500 may cover the first touch signal line 411, and the second touch signal line 421 may be spaced apart from the first organic layer 500 in 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 may 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 on the same layer, thereby reducing the risk of short circuit between the touch signal lines. Additionally, it can also weaken the interference between adjacent touch signal lines.

[0134] 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.

[0135] FIG. 4 is a schematic top view of a display panel provided by an embodiment of the present disclosure, and FIG. 4 can correspond to the top view structure shown in FIG. 3. Exemplarily, referring to FIG. 4, for the third region 230, the width of the first touch signal line 411 in the first direction is the first dimension a, and the width of the second touch signal line 421 in the first direction is the second dimension b. 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.

[0136] 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.

[0137] In some examples, the same touch signal line includes the first touch signal or the second touch signal line. The first touch signal line and the second touch signal line are alternately arranged in the first direction X, where the first direction intersects with the second direction, and the second direction is the length direction of the touch signal line.

[0138] For example, referring to FIG3, the first touch signal line 411 and the second touch signal line 421 are spaced apart in the first direction X. The second touch signal line 421 can be spaced apart from the first organic layer 500, and the second touch signal line 421 can be in the same plane as the first touch signal line 411. The distance between the second touch signal line 421 and the first organic layer 500 can prevent adjacent second touch signal lines 421 from conducting through metal etching residues on the surface of the first organic layer 500 away from the substrate layer 310 in the first direction X. At the same time, the alternating arrangement of 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 conduct through metal etching residues on the upper surface of the first organic layer 500. The first direction X can be a direction parallel to the plane where the driving layer 320 is located.

[0139] In some examples, the first organic layer includes a first cutout, the orthographic projection of the first cutout onto the substrate layer falling into the spacing region between adjacent first touch signal lines, and the orthographic projection of the second touch signal line onto the substrate layer falling into the orthographic projection of the first cutout onto the substrate layer.

[0140] For example, referring to FIG3, the first organic layer 500 may be disposed on the side of the first touch signal line 411 away from the driving layer 320. A first cutout 510 is formed on the first organic layer 500 by etching process. A second touch signal line 421 is disposed 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 cutout 510 is retained by etching process. The size of the first cutout 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 driving layer 320 falls within the orthographic projection of the first cutout 510 on the driving layer 320. The first cutout 510 can form a gap 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 cutout 510. That is, during the etching process of the second touch signal line 421, some of the second touch signal line 421 will remain on the side of the first organic layer 500 away from the driving layer 320, thereby avoiding the phenomenon of electrical connection between adjacent touch signal lines.

[0141] For example, referring to FIG4, the first cutout 510 of the first organic layer 500 is used to form the second touch signal line 421, and the distance between the wall of the first organic layer 500 corresponding to the first cutout 510 and the second touch signal line 421 can be a first distance c.

[0142] In some examples, the same touch signal line includes a first touch signal line or a second touch signal line, which are arranged alternately in a first direction. A first organic layer covers the first touch signal line, and adjacent second touch signal lines are spaced apart from the first touch signal line by the first organic layer in a third direction, wherein the third direction is a direction perpendicular to the plane of the driving layer.

[0143] Figure 5 is a schematic partial structural diagram of another display panel provided in an embodiment of this disclosure. Referring to Figure 5, for the third region 230, a first organic layer 500 can be retained, and a second touch signal line 421 is formed on the side of the first organic layer 500 away from the first touch signal line 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 intervals 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 to conduct through the surface of the first organic layer 500 in the first direction.

[0144] Figure 6 is a schematic top view of another display panel provided in an embodiment of this disclosure, and Figure 6 can correspond to the top view structure shown in Figure 5. For example, referring 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, the distance between the first touch signal line 411 and the second touch signal line 421 in Figure 6 is smaller than the first distance c in Figure 4, thereby allowing for more touch signal lines to be provided to improve signal transmission efficiency. Furthermore, the increased distance between the second touch signal lines 421 reduces the risk of short circuits caused by etching residues in the second touch electrode layer between adjacent second touch signal lines.

[0145] In some examples, the first distance c is less than or equal to 10 μm.

[0146] In some examples, the first organic layer located in the first region 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.

[0147] Figure 7 is a schematic top view of a display panel provided in an embodiment of this disclosure. Referring to Figure 7, for example, a first touch signal line 411 may be disposed on a first touch electrode layer 410, and a second touch signal line 421 may be disposed on a second touch electrode layer 420. The first touch signal line 411 and the second touch signal line 421 are disposed on different layers, and the first touch signal line 411 of the same touch signal line can be electrically connected to the second touch signal line 421 through a first via 450.

[0148] For example, referring to FIG7, 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, as shown in FIG7. L1>L2, thereby increasing the space of the second touch electrode layer 420 and reducing the risk of short circuit caused by incomplete etching of the second touch signal line 421.

[0149] In some examples, the length of the first touch signal line is greater than the length of the second touch signal line, and the widths of the first touch signal line and the second touch signal line are different.

[0150] Figure 8 is a schematic top view of another display panel provided in an embodiment of this disclosure. Referring, by way of example, the length of the first touch signal line in the second direction is less than the length of the second touch signal line in the second direction.

A first organic layer 500 is disposed between the first touch electrode layer 410 and the second touch electrode layer 420. An encapsulation layer 330 is disposed between the touch electrode layer and the driving layer 320. A first inorganic layer 800 is disposed between the encapsulation layer 330 and the touch electrode layer. The thickness of the first organic layer 500 is greater than the thickness of the first inorganic layer 800. A second organic layer 600 is disposed on the side of the touch electrode layer furthest from the driving layer 320, and the thickness of the second organic layer 600 is greater than the thickness of the first organic layer 500.

[0152] For example, the encapsulation layer may include two inorganic layers and one organic layer, with the organic layer disposed between the two inorganic layers, and a light-emitting device may also be included between the encapsulation layer and the driving layer.

[0153] In some examples, the touch electrode layer includes at least two conductive layers stacked together.

For the third region, the orthographic projection of the third organic layer 700 on the substrate layer 310 does not overlap with the orthographic projection of the touch signal line on the substrate layer 310.

[0159] The at least two-layer touch electrode system includes a first touch electrode layer 410 and a second touch electrode layer 420. The first touch electrode layer 410 is disposed between the driving layer 320 and the second touch electrode layer 420. A first organic layer 500 is disposed between the first touch electrode layer 410 and the second touch electrode layer 420. Touch signal lines can be disposed on a single first touch electrode layer 410, and the first organic layer 500 covers the touch signal lines.

[0160] For example, the third organic layer corresponding to the third region of the non-display area can be removed by an etching process, and the remaining film layers can be the first inorganic layer, the first touch signal line, the first organic layer, the second touch signal line, and the second organic layer respectively in the third direction, where the third direction is the direction from the substrate layer to the driving layer.

For the third region, the orthographic projection of the third organic layer onto the substrate overlaps with the orthographic projection of the touch signal line onto the substrate.

[0162] For example, the film layers corresponding to the third region of the display area can be, in the third direction, a first inorganic layer, a third organic layer, a first touch signal line, a first organic layer, a second touch signal line, and a second organic layer, respectively, with the third direction being the direction from the substrate layer towards the driving layer. Simultaneously, the first organic layer can be etched using the above-described technique to prevent adjacent touch signal lines from conducting through the surface of the first organic layer. The third organic layer can be etched using the same etching method as the first organic layer to prevent adjacent first touch signal lines from conducting.

[0163] In some examples, the at least two-layer touch electrode layer includes a first touch electrode layer and a second touch electrode layer. The first touch electrode layer is disposed between the driving 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. Touch signal lines are disposed on a single second touch electrode layer. The first organic layer includes a second cutout, and the orthographic projection of the touch signal line on the substrate layer does not overlap with the orthographic projection of the second cutout on the substrate layer.

[0164] Figure 12 is a schematic partial structural diagram of another display panel provided in an embodiment of this disclosure. Referring to Figure 12, for the third region 230, a second cutout 520 can be formed on the first organic layer 500 by an etching process. A second touch signal line 421 is disposed on the side of the first organic layer 500 away from the substrate layer 310, that is, the second touch signal line 421 is not coplanar with the first organic layer 500. There is a gap between the first organic layers 500 in the first direction X, and the gap distance can be the size of the second cutout 520 in the first direction X.

[0165] In some examples, a first touch lead is provided in a first region, and a second touch lead is provided in a second region. The first touch lead is electrically connected to the touch electrode and the second touch lead, respectively, and the second touch lead is electrically connected to the touch signal line.

[0166] For example, touch leads are used for electrical connections between touch signal lines and display areas.

[0167] In some examples, the touch electrode layer comprises a stacked structure of multiple metal layers to form corresponding touch signal lines.

[0168] In some examples, the material of the first organic layer may include a low-temperature polymerized material.

[0169] For example, the material of the first organic layer may be acrylate, siloxane or epoxy ester.

[0170] In some examples, the material of the second organic layer may include a low-temperature polymerized material.

[0171] In some examples, the material of the third organic layer may include a low-temperature polymerized material.

[0172] In some examples, the thickness of the first organic layer in the third direction is 1 μm.

[0173] For example, the thickness of the first organic layer can be close to 1 μm, such as 0.8 μm, 1 μm or 1.2 μm.

[0174] In some examples, the thickness of the second organic layer in the third direction is greater than 1 μm.

[0178] In some examples, the first dimension of the first touch signal line in the first direction is less than or equal to 50 μm. The second dimension of the second touch signal line in the first direction is less than or equal to 50 μm.

[0179] A second aspect of this disclosure is illustrated in FIG13, which is a schematic partial structural diagram of a display area of ​​a display panel according to an embodiment of this disclosure. Referring to FIG13, another display panel is provided, 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, with the driving layer 320 disposed on one side of the substrate layer 310. At least two touch electrode layers are disposed 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 disposed between the at least two touch electrode layers. The driving layer 320 includes a display area and a non-display area. 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 bonding 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 disposed on at least one touch electrode layer. The touch signal lines are electrically connected to a portion of the bonding pins and 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 lines on the substrate layer.

[0180] For example, referring to FIG13, 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 connected in parallel to reduce the resistance of the touch signal line and improve the signal transmission efficiency of the display panel.

[0181] For example, all first organic layers in the non-display area can be removed, the first organic layer in the third area can be removed separately, or the first organic layers in the first and third areas can be removed separately.

[0182] In some examples, the at least two-layer touch electrode layer includes a first touch electrode layer and a second touch electrode layer, wherein the first touch electrode layer is disposed between the driving 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;

[0183] The touch signal line includes a first conductive structure and a second conductive structure. The first conductive structure is disposed on a first touch electrode layer, and the second conductive structure is disposed on a second touch electrode layer. In a third area outside the display area, the surface of the first conductive structure furthest from the driving layer is connected to the surface of the second conductive structure closest to the driving layer. The first and second conductive structures can be overlapped to form the touch signal line. There can be no dielectric material between the first and second conductive structures, which reduces the resistance of the touch signal line and prevents short circuits caused by adjacent touch signal lines being connected through a dielectric material.

[0184] In some examples, the size of the first conductive structure in the first direction is smaller than the size of the second conductive structure in the first direction, the first direction intersects the second direction, and the second direction is the length direction of the touch signal line.

[0185] Figure 14 is a schematic top view of another display panel provided in an embodiment of this disclosure. Figure 14 can correspond to the top view structure shown in Figure 13. For example, referring to Figure 14, the dimension of the first conductive structure 430 in the first direction X can be a first dimension a, and the dimension of the second conductive structure 440 in the first direction X can be a second dimension b. In the direction of the plane where the driving layer 320 is located, i.e., in the first direction X, the dimension of the first conductive structure 430 is smaller than the dimension of the second conductive structure 440, i.e., a. <b,。

[0186] In some examples, the second conductive structure has a second dimension in the first direction, which is larger than the first dimension, and the difference between the second dimension and the first dimension is less than or equal to 10 μm.

[0187] In some examples, the at least two-layer touch electrode layer includes a first touch electrode layer and a second touch electrode layer, with the first touch electrode layer disposed between the driving layer and the first organic layer, and the first organic layer disposed between the first touch electrode layer and the second touch electrode layer.

[0188] 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 a direction perpendicular to the plane of the driving layer. The first touch signal line is disposed on a first touch electrode layer, and the second touch signal line is disposed on a second touch electrode layer. In the third region, the second touch signal line can overlap with the first touch signal line and be disposed in parallel with the first touch signal line. At the same time, the first organic layer passes through the etching process area, and adjacent second touch signal lines will not be conductive, thereby improving the signal transmission efficiency of the display panel.

[0189] For example, referring to FIG13, 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 disposed 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.

[0190] In some examples, the touch signal line includes a second touch signal line disposed on the second touch electrode layer.

[0191] Figure 15 is a schematic partial structural diagram of another display panel provided in an embodiment of this disclosure. Referring to Figure 15, for example, the 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.

[0192] 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 driving layer and the touch electrode layer. The second organic layer is disposed on the side of the touch electrode layer furthest from the driving layer, away from the driving layer. The third organic layer is disposed between the touch electrode layer and the encapsulation layer. The first inorganic layer is disposed between the third organic layer and the encapsulation layer. The orthographic projection of the third organic layer on the substrate does not overlap with the orthographic projection of the touch signal line on the substrate.

[0193] Figure 16 is a schematic partial structural diagram of a display panel provided in an embodiment of this disclosure. Referring to Figure 16, by means of an etching process, the first organic layer 500 and the third organic layer 700 corresponding to the non-display area 200 can be removed. The film layers corresponding to the third region 230 of the non-display area 200 can be, respectively, a first inorganic layer 800, a first touch signal line 411, a second touch signal line 421, and a second organic layer 600 in the third direction Z, where the third direction Z is the direction from the substrate layer 310 toward the driving layer 320.

[0194] For example, the encapsulation layer may include two inorganic layers and one organic layer, with the organic layer disposed between the two inorganic layers, and a light-emitting device may also be included between the encapsulation layer and the driving layer.

[0195] 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 driving layer and the touch electrode layer. The second organic layer is disposed on the side of the touch electrode layer furthest from the driving layer, away from the driving layer. The third organic layer is disposed between the touch electrode layer and the encapsulation layer. The first inorganic layer is disposed between the third organic layer and the encapsulation layer. The orthographic projection of the third organic layer on the substrate overlaps with the orthographic projection of the touch signal line on the substrate.

[0196] Figure 17 is a schematic partial structural diagram of another display panel provided in an embodiment of this disclosure. Referring to Figure 17, for example, the first organic layer 500 corresponding to the non-display area 200 can be removed by an etching process. The film layers corresponding to the third region 230 of the non-display area 200 can be, respectively, a first inorganic layer 800, a third organic layer 900, a first touch signal line 411, a second touch signal line 421, and a second organic layer 600 in the third direction Z, where the third direction Z is the direction from the substrate layer towards the driving layer.

[0197] In some examples, the touch signal lines can consist of only a first touch signal line, meaning the touch signal lines are disposed on a single first touch electrode layer. This ensures the flatness of the underlying substrate during touch signal line deposition. Furthermore, since the touch signal lines are made of metal, which is susceptible to corrosion from water and oxygen, using a single-layer touch signal line reduces the amount of metal required, avoiding interference between different touch signal lines and improving the reliability of the display panel.

[0198] For example, the touch signal line can consist of only a second touch signal line, meaning the touch signal line is disposed on a single second touch electrode layer. For the third region, there may be no first organic layer between the second touch signal line and the first touch electrode layer, thus reducing the metal layer on the display panel and avoiding interference between different touch signal lines, thereby improving the reliability of the display panel.

[0199] 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 instance, a segmented first touch signal line and a segmented second touch signal line can be connected to form a single touch signal line. Electrical connection between the first and second touch signal lines is achieved by drilling holes in the first organic layer. For the third region, after completely etching the first organic layer, no short circuits will occur between adjacent touch signal lines.

[0200] A third aspect of this disclosure, FIG18 is a schematic partial structural diagram of another display panel provided in an embodiment of this disclosure. Referring to FIG18, another display panel is provided, including a driving layer 300, a touch electrode layer, a third inorganic layer 900, and a third organic layer 700. The touch electrode layer is disposed on one side of the driving layer 320, and includes a first touch electrode layer 410 and a second touch electrode layer 420. The touch electrode layer is provided with touch electrodes, and the first touch electrode layer 410 is disposed between the driving layer 320 and the second touch electrode layer 420. The third inorganic layer 900 is disposed between the first touch electrode layer 410 and the second touch electrode layer 420. The third organic layer 700 is disposed between the driving layer 320 and the first touch electrode layer 410.

[0201] In some examples, the driving layer includes a display area and a non-display area, with the non-display area at least partially surrounding the display area. The non-display area includes a first area, a second area, and a third area, with the second area located between the first and third areas, the first area located between the second area and the display area, the third area having bonding pins, the display panel corresponding to the second area being foldable, the first area having touch signal lines electrically connected to a portion of the bonding pins, and the touch signal lines being electrically connected to touch electrodes.

[0202] In some examples, referring to Figure 18, the orthographic projection of the third organic layer 700 onto the driving layer 320 overlaps with the orthographic projection of the touch signal line onto the driving layer 320.

[0203] In some examples, referring to FIG18, the third inorganic layer 900 includes a second via 910, and the same touch signal lines include a first touch signal line 411 and a second touch signal line 421. The first touch signal line 411 is disposed on the first touch electrode layer 410, and the second touch electrode layer 421 is disposed 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 via 910.

[0204] In some examples, the touch signal line is located on the second touch electrode layer.

[0205] In some examples, the touch signal lines can consist of only a first touch signal line, meaning the touch signal lines are disposed on a single first touch electrode layer. This ensures the flatness of the underlying substrate during touch signal line deposition. Furthermore, since the touch signal lines are made of metal, which is susceptible to corrosion from water and oxygen, using a single-layer touch signal line reduces the amount of metal required, avoiding interference between different touch signal lines and improving the reliability of the display panel.

[0206] For example, the touch signal line may only be a second touch signal line, that is, the touch signal line is set on a single second touch electrode layer.

[0207] 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 instance, a segmented first touch signal line and a 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 can be achieved by drilling holes in the first organic layer.

[0208] In some examples, the touch electrode layer comprises a stacked structure of multiple metal layers to form corresponding touch signal lines.

[0209] Figure 19 is a schematic partial structural diagram of a display panel provided in an embodiment of this disclosure. Referring to Figure 19, for example, the first touch signal line 411 can be a stacked structure of three metal layers, and the second touch signal line 421 can also be a stacked structure of three metal layers.

[0210] In some examples, the touch electrode layer may include a three-layer stack structure of molybdenum-aluminum-molybdenum, with the stack direction being the third direction.

[0211] In some examples, the touch electrode layer may include a three-layer stacked structure of titanium-aluminum-titanium, with the stacking direction being the third direction.

[0212] In some examples, the touch electrode layer may include a three-layer stack structure of indium tin oxide-silver-indium tin oxide, with the stack direction being the third direction.
