Description

Technical Field

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

[0002] With the continuous development of display technology, consumers' requirements for display panels are constantly increasing. Various types of display panels have emerged and developed rapidly, such as liquid crystal display panels, organic light-emitting display panels, etc. On this basis, 3D display, touch display technology, curved display, ultra-high resolution display and anti-peeping display and other display technologies continue to emerge to meet consumer needs. The touch function is basically one of the necessary functions for current display screens. The implementation form and structure of the touch function are also diverse, such as self-capacitive, mutual-capacitive and other touch modes, built-in, external or plug-in touch structures.

[0003] However, due to the existing manufacturing process and structural limitations of display panels, the manufacturing yield of display panels cannot meet the requirements. Summary of the invention

[0004] The display panel and the display device provided by the embodiments of the present application can effectively improve the manufacturing yield of the display panel.

[0005] On the one hand, according to an embodiment of the present application, a display panel is proposed, the display panel includes a first area and a second area arranged around the first area, and the display panel also includes a substrate, a display light-emitting layer and a touch layer. The display light-emitting layer is arranged on the substrate, and the display light-emitting layer includes a plurality of support structures, the support structure includes a first sub-support structure and a second sub-support structure, and the size of the first sub-support structure in the thickness direction of the display panel is greater than the size of the second sub-support structure in the thickness direction of the display panel. The touch layer includes a touch electrode and a plurality of touch wirings, the touch wirings are electrically connected to the touch electrodes, the touch electrodes are located in the first area, and the touch wirings are located in the second area. Among them, the orthographic projection of at least some of the multiple touch wirings on the substrate does not overlap with the orthographic projection of the first sub-support structure on the substrate.

[0006] On the other hand, an embodiment of the present application further provides a display device, comprising the display panel as described above.

[0007] According to the display panel and display device provided by the present application, the support structure can support the mask plate to realize the preparation of the light-emitting film layer in the display panel, and the touch line is used to realize the signal transmission of the touch electrode. Since the size of the first sub-support structure in the thickness direction is larger than the size of the second sub-support structure in the thickness direction, the upper film layer of the area where the first sub-support structure is located protrudes from the upper film layer of the area where the second sub-support structure is located in the direction parallel to the display panel. By arranging the orthographic projection of the touch line 42 on the substrate 10 and the orthographic projection of the first sub-support structure 211 on the substrate 10 without overlapping, the touch line avoids the uneven area of ​​the film layer below the touch line, thereby reducing the risk of cracking or even disconnection of the touch line due to the uneven film layer below the touch layer (the film layer above the support structure), thereby improving the preparation yield of the display panel.

[0039] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0040] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0041] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0042] The display panel includes a display light-emitting layer, which includes a light-emitting layer and a support structure arranged on a substrate. Before the light-emitting layer is prepared, a mask plate is covered on the substrate and supported by the support structure. During the preparation of the light-emitting layer, some light-emitting layer materials will adhere to the mask plate. After accumulating to a certain extent, the light-emitting layer materials will fall onto the support structure, resulting in an increase in the overall height of the support structure. After the light-emitting layer is prepared, it is usually necessary to prepare an encapsulation layer. Due to the change in the overall height of the support structure, the prepared encapsulation layer will be uneven. The touch wiring is arranged on the encapsulation layer. The touch wiring will be broken or even disconnected by the protruding structure at the position of the support structure, resulting in the touch wiring being unable to transmit the touch signal normally, resulting in a decrease in the preparation yield.

[0043] In order to solve the above problems, in a first aspect, an embodiment of the present application provides a display panel.

Figure 2 A schematic structural diagram of another display panel provided for some embodiments of the present application. Figure 3 A schematic diagram of the cross-sectional structure of a display panel provided in some embodiments of the present application. Figure 4 for Figure 3 Schematic diagram of a local structure of Q.

[0045] like Figures 1 to 4As shown, an embodiment of the present application provides a display panel 100. The display panel 100 includes a first area A1 and a second area A2 arranged around the first area A1. The display panel 100 also includes a substrate 10, a display light-emitting layer 20, and a touch layer 40. The display light-emitting layer 20 is arranged on the substrate 10, and the display light-emitting layer 20 includes a plurality of support structures 21. The support structure 21 includes a first sub-support structure 211 and a second sub-support structure 212. The size of the first sub-support structure 211 in the thickness direction Z of the display panel 100 is greater than the size of the second sub-support structure 212 in the thickness direction Z of the display panel 100. The touch layer 40 includes a touch electrode 41 and a plurality of touch traces 42. The touch traces 42 are electrically connected to the touch electrode 41. The touch electrode 41 is located in the first area A1, and the touch traces 42 are located in the second area A2. Among them, the orthographic projection of at least some of the touch traces 42 on the substrate 10 does not overlap with the orthographic projection of the first sub-support structure 211 on the substrate 10.

[0046] In some examples, the first area A1 may be a display area, and the second area A2 may be a non-display area. For example, the first area A1 may be used for displaying the display function of the display panel 100. The second area A2 may be used to set structures such as photosensitive devices, metal wiring, and frames.

[0047] In other examples, the first area A1 may also be a touch area, and the second area A2 may be a non-touch area. Optionally, the touch area may include a display area, and may also include a portion of a non-display area. The following example takes the first area A1 as a touch area and the second area A2 as a non-touch area.

[0048] The substrate 10 mainly plays a supporting and bearing role, and other film layers are stacked in sequence on the substrate 10. The stacking arrangement mentioned here means that other film layers are stacked in sequence along the thickness direction Z of the substrate 10. Among them, the substrate 10 may include a single or multiple film layer structures, and the specific film layer structure composition of the substrate 10 is not limited in the embodiment of the present application. And the thickness direction Z of other film layers located on one side of the substrate 10 is usually consistent with the thickness direction Z of the substrate 10 itself. Therefore, for the convenience of expression, the thickness direction Z of the substrate 10 or the thickness direction Z of other film layers mentioned later in the embodiment of the present application are all illustrated in the same direction. The substrate 10 may be a rigid substrate 10, for example, including a glass substrate 10. Alternatively, the substrate 10 may be a flexible substrate 10, for example, including an organic material such as polyimide.

[0049] The display light-emitting layer 20 may include a light-emitting layer 22. Exemplarily, the light-emitting layer 22 is located on the substrate 10, and in a direction parallel to the plane where the substrate 10 is located, the light-emitting layer 22 includes a plurality of light-emitting units, and the light-emitting unit is the main device for realizing light-emitting display. The light-emitting layer 22 of each light-emitting unit may include a light-emitting functional layer. Alternatively, the light-emitting layer 22 may include at least one of a stacked hole injection layer (Hole Inject Layer, HIL), a hole transport layer (Hole Transport Layer, HTL), an electron blocking layer, a hole blocking layer, an electron injection layer (Electron Inject Layer, EIL) and an electron transport layer (Electron Transport Layer, ETL).

[0050] The display light-emitting layer 20 includes a support structure 21, and the support structure 21 can be arranged on the substrate 10. Alternatively, the display light-emitting layer 20 can also include a pixel definition layer, the pixel definition layer includes a pixel definition part and a pixel opening, the light-emitting layer 22 is arranged in the pixel opening, the pixel definition part encloses to form the pixel opening, and the support structure 21 can be arranged on the side of the pixel definition part facing away from the substrate 10.

[0051] The first sub-support structure 211 is used to support the mask plate to realize the preparation of the light-emitting film layer in the display panel 100. Exemplarily, the shape of the mask plate is rectangular, and the first sub-support structure 211 supports the four corners of the mask plate.

[0052] Optionally, the first sub-support structure 211 and the second sub-support structure 212 may be arranged at intervals. Alternatively, the second sub-support structure 212 is arranged on the peripheral side of the first sub-support structure 211. Alternatively, the first sub-support structure 211 is arranged on the peripheral side of the second sub-support structure 212.

[0053] Exemplarily, when the second sub-support structure 212 is arranged on the side of the first sub-support structure 211, during the preparation of the light-emitting film layer, when a portion of the light-emitting material drips onto the first sub-support structure 211 along the mask plate, this portion of the light-emitting material can slide along the side wall of the second sub-support structure 212, thereby reducing the possibility that the light-emitting material drips onto the first sub-support structure 211 and causes the size of the first sub-support structure 211 to increase in the thickness direction.

[0054] Exemplarily, when the first sub-support structure 211 and the second sub-support structure 212 can be arranged at intervals, during the preparation process of the light-emitting film layer, when the mask plate is deformed due to the light-emitting material adhering to the mask plate, the second sub-support structure 212 can support the mask plate, thereby reducing the possibility of abnormal position of the light-emitting film layer or even color mixing caused by deformation of the mask opening due to deformation of the mask plate.

[0055] The touch layer 40 includes touch electrodes 41 and touch traces 42. Optionally, the touch electrodes 41 can realize the touch function by mutual capacitance and / or self capacitance. Exemplarily, the touch electrodes 41 include transmitting electrodes and sensing electrodes, and the transmitting electrodes and the sensing electrodes are connected to different touch traces 42.

[0056] The touch electrode 41 is located in the first area A1, so that the first area A1 forms a touch area. When the user's fingertip or any conductive object touches the first area A1 of the screen, an accurate coordinate signal can be immediately triggered to accurately locate the contact point to achieve interaction with the user.

[0057] The touch line 42 is located in the second area A2 and can extend along the shape of the second area A2. For example, the second area A2 is rectangular and the touch line 42 extends along the extending direction of the rectangular edge. Alternatively, the second area A2 is circular and the touch line 42 extends in an arc shape.

[0058] In some embodiments, the orthographic projections of the plurality of touch lines 42 on the substrate 10 and the orthographic projections of the first sub-support structure 211 on the substrate 10 are not overlapped. In other embodiments, the orthographic projections of a portion of the plurality of touch lines 42 on the substrate 10 and the orthographic projections of the first sub-support structure 211 on the substrate 10 are not overlapped. The "non-overlapping" here may mean that the orthographic projections of the touch lines 42 on the substrate 10 and the orthographic projections of the first sub-support structure 211 on the substrate 10 are arranged at intervals. Alternatively, the orthographic projections of the touch lines 42 on the substrate 10 are arranged tangent to the edges of the orthographic projections of the first sub-support structure 211 on the substrate 10. Optionally, both the first sub-support structure 211 and the second sub-support structure 212 are disposed in the second area A2; or, neither the first sub-support structure 211 nor the second sub-support structure 212 is disposed in the second area A2; or, the first sub-support structure 211 is not disposed in the second area A2, and the second sub-support structure 212 is disposed in the second area A2; or, the first sub-support structure 211 is disposed in the second area A2, and the second sub-support structure 212 is not disposed in the second area A2. When the first sub-support structure 211 is not disposed in the second area A2, the first sub-support structure 211 may be disposed in the first area A1. When the second sub-support structure 212 is not disposed in the second area A2, the second sub-support structure 212 may be disposed in the first area A1.

[0059] In some embodiments, the orthographic projections of the plurality of touch traces 42 on the substrate 10 do not overlap with the orthographic projections of the second sub-support structure 212 on the substrate 10. In other embodiments, at least a portion of the orthographic projections of the plurality of touch traces 42 on the substrate 10 overlap with the orthographic projections of the second sub-support structure 212 on the substrate 10.

[0060] According to the display panel 100 provided in the present application, the support structure 21 can support the mask plate to realize the preparation of the light-emitting film layer in the display panel 100 , and the touch wiring 42 is used to realize the signal transmission of the touch electrode 41 . When preparing the light-emitting film layer, some light-emitting materials will drip along the mask plate onto the first sub-support structure and the second sub-support structure. As the light-emitting materials accumulate on the first sub-support structure and the second sub-support structure, the sizes of the first sub-support structure and the second sub-support structure in the thickness direction will increase. Since the size of the first sub-support structure 211 in the thickness direction Z is larger than the size of the second sub-support structure 212 in the thickness direction Z, the upper film layer in the area where the first sub-support structure 211 is located protrudes out of the upper film layer in the area where the second sub-support structure 212 is located in a direction parallel to the display panel. By arranging the orthographic projection of the touch line 42 on the substrate 10 and the orthographic projection of the first sub-support structure 211 on the substrate 10 to be non-overlapping, the touch line avoids the uneven area of ​​the film layer below the touch line, thereby reducing the risk of cracking or even breaking of the touch line 42 due to the uneven film layer below the touch layer 40 (the film layer above the support structure 21), thereby improving the preparation yield of the display panel 100.

[0061] In some embodiments, an encapsulation layer 30 is further provided between the display light-emitting layer 20 and the touch layer 40. For example, the encapsulation layer 30 includes a first encapsulation layer, a second encapsulation layer, and a third encapsulation layer, and the first encapsulation layer, the second encapsulation layer, and the third encapsulation layer may be provided between the support structure 21 and the touch layer 40 at the same time. Of course, one or more combinations of the first encapsulation layer, the second encapsulation layer, and the third encapsulation layer may be provided between the support structure 21 and the touch layer 40.

[0062] Figure 5 for Figure 2 Schematic diagram of a local structure of P. Figure 5 And the following Figures 6 to 10 , Fig.12 as well as Fig.15 The thick solid line in the figure is only used to distinguish it from other structures, and the radial dimensions of the structure are not different.

[0063] like Figures 2 to 5 As shown, in some optional embodiments, at least part of the first sub-support structure 211 and / or the second sub-support structure 212 is disposed in the second area A2.

[0064] In some embodiments, the plurality of first sub-support structures 211 are all disposed in the second area A2. In other embodiments, a portion of the plurality of first sub-support structures 211 are disposed in the second area A2, and another portion are disposed in the first area A1 and / or the second area A2.

[0065] In some embodiments, the plurality of second sub-support structures 212 are all disposed in the second area A2. In other embodiments, a portion of the plurality of second sub-support structures 212 are disposed in the second area A2, and another portion are disposed in the first area A1 and / or the second area A2.

[0066] In some embodiments, the plurality of first sub-support structures 211 and the plurality of second sub-support structures 212 are both disposed in the second area A2. In other embodiments, a portion of the plurality of first sub-support structures 211 is disposed in the second area A2, another portion of the plurality of first sub-support structures 211 is disposed in the first area A1, and a portion of the plurality of second sub-support structures 212 is disposed in the second area A2, another portion of the plurality of second sub-support structures 212 is disposed in the first area A1.

[0067] In these optional embodiments, by arranging the first sub-support structure 211 and / or the second sub-support structure 212 in the second area A2, it is beneficial to increase the support area of ​​the mask plate, thereby reducing the possibility that the mask plate will deform and contact the film layer in the display panel 100, resulting in a decrease in the preparation yield of the light-emitting layer 22.

[0068] like Figure 3 and Figure 4 As shown, in some optional embodiments, the second sub-support structure 212 is disposed around the circumference of the first sub-support structure 211 , and the second sub-support structure 212 is connected to the side wall of the first sub-support structure 211 .

[0069] Exemplarily, the first sub-support structure 211 and the second sub-support structure 212 together form a frustum or a cone.

[0070] In these optional embodiments, the first sub-support structure 211 can serve as the main structure for supporting the mask plate, and the second sub-support structure 212 can be used to disperse the stress borne by the first sub-support structure 211. In addition, since the second sub-support structure 212 is connected to the side wall of the first sub-support, the overall stability and reliability of the support structure 21 are improved.

[0071] Figure 6 for Figure 2 Another partial structural diagram of P.

[0072] like Figures 2 to 6As shown, in some optional embodiments, the second area A2 includes a first sub-area arranged around the first area A1 and a second sub-area located in the first sub-area facing away from the first area A1. The display panel 100 includes a mask area MK, the mask area covers the first area A1 and the first sub-area, the mask area MK includes a corner area MK1, the corner area covers the first area A1 and the corners of the first sub-area, and the first sub-support structure 211 and / or the second sub-support structure 212 are arranged in the corner area MK1.

[0073] Optionally, the shape of the first sub-area and the shape of the second sub-area match the shape of the first area A1, for example, the shape of the first area A1 is rectangular, and the shapes of the first sub-area and the second sub-area are both rectangular rings. For example, the shape of the first area A1 is circular, and the shapes of the first sub-area and the second sub-area are both circular rings.

[0074] Optionally, the second sub-region is arranged around the first sub-region.

[0075] Optionally, the mask area MK may be an area where a mask plate is arranged during the preparation of the light-emitting layer 22. The mask area MK also includes a corner area MK1, which covers the first area A1, and the corner area MK1 also covers the corners of the first sub-area, which are often structurally fragile and easily damaged. The first sub-support structure 211 is arranged in the corner of the first sub-area, which is conducive to enhancing the mechanical stability and durability of the corner area MK1 of the first sub-area.

[0076] In these optional embodiments, the above configuration is helpful to improve the structural stability of the mask plate supported by the support structure 21 and reduce the interference of the support structure 21 on the touch wiring 42 .

[0077] like Figure 5 and Figure 6 As shown, in some optional embodiments, the orthographic projection of the first sub-support structure 211 and / or the second sub-support structure 212 on the substrate 10 does not overlap with the orthographic projection of the touch trace 42 on the substrate 10 .

[0078] Exemplarily, the orthographic projection of the first sub-support structure 211 on the substrate 10 does not overlap with the orthographic projection of the touch line 42 on the substrate 10. For example, the orthographic projection of the first sub-support structure 211 on the substrate 10 and the orthographic projection of the touch line 42 on the substrate 10 are spaced apart; or, the orthographic projection of the first sub-support structure 211 on the substrate 10 is tangent to the edge of the orthographic projection of the touch line 42 on the substrate 10.

[0079] Exemplarily, the orthographic projection of the second sub-support structure 212 on the substrate 10 does not overlap with the orthographic projection of the touch line 42 on the substrate 10. For example, the orthographic projection of the second sub-support structure 212 on the substrate 10 and the orthographic projection of the touch line 42 on the substrate 10 are spaced apart from each other; or, the orthographic projection of the second sub-support structure 212 on the substrate 10 is tangent to the edge of the orthographic projection of the touch line 42 on the substrate 10.

[0080] In these optional embodiments, through the above-mentioned settings, the touch wiring 42 avoids the area where the first sub-support structure 211 and / or the second sub-support structure 212 are provided in the lower film layer, further reducing the impact of abnormal thickness uniformity on the touch wiring 42 when the film layer above the first sub-support structure 211 and the second sub-support structure 212 occurs, thereby improving the preparation yield of the touch wiring 42.

[0081] like Figure 2 As shown, in some optional embodiments, the display panel 100 further includes a control chip IC, which is located in a second area A2 on one side of the first area A1 along the first direction X, and the corner area MK1 is located at a corner of the first area A1 along the first direction X close to the control chip IC.

[0082] Optionally, taking the shape of the second area A2 as a rectangular ring as an example, the long side areas of the second area A2 are located on both sides of the first area A1 along the second direction Y, the short side areas of the second area A2 are located on both sides of the first area A1 along the first direction X, the control chip IC is located in the short side area of ​​the second area A2, the corner area MK1 is the corner close to the control chip IC along the first direction X, and arranging a support structure 21 in the corner area MK1 helps to improve the overall strength of the corner area MK1, reduce the possibility of damage to the control chip IC during the preparation process or under external forces, and improve reliability.

[0083] Figure 7 for Figure 2 Another partial structural diagram of P. Figure 8 for Figure 2 Another partial structural diagram of P.

[0084] like Figure 7 and Figure 8 As shown, in some optional embodiments, the touch layer 40 further includes a virtual touch wiring 43, the virtual touch wiring 43 is insulated from the touch wiring, and the virtual touch wiring 43 is arranged in the corner area MK1.

Part of the light shielding portions 52 are arranged in the corner area MK1.

[0095] Optionally, the filter unit 51 in the filter layer 50 may be arranged opposite to the light-emitting layer in the display light-emitting layer 20 .

[0096] Optionally, the light shielding portion 52 may enclose an opening area in the first area A1, and the filter unit 51 is disposed in the opening area.

[0097] Optionally, the filter portion may selectively transmit or block light of a specific wavelength according to design requirements to achieve color display or enhance the saturation of a specific color.

[0101] In these optional embodiments, by setting the shading portion 52 in the corner area MK1, the shapes of the shading of various areas in the first sub-area are made the same, thereby improving the display uniformity in the first sub-area, reducing the possibility of local display abnormalities, and improving the display effect.

[0102] like Figure 6 As shown, in some optional embodiments, the display panel 100 includes a mask area MK, and the mask area MK includes a corner area MK1. The touch line 42 includes a first segment 421 and a second segment 422 connected to each other, pointing from the first area A1 to the second area A2, the first segment 421 is arranged in a first sub-area that does not overlap with the corner area MK1, and the second segment is arranged in a second sub-area that overlaps with the corner area.

[0103] The touch line 42 includes a first section 421 and a second section 422 connected to each other, and points from the first area A1 to the second area A2. The first section 421 is arranged in a first sub-area that does not overlap with the corner area MK1, and the second section 422 is arranged in a second sub-area that overlaps with the corner area MK1.

[0104] The touch trace 42 includes a first section 421 and a second section 422 connected to each other. Taking the shape of the first area A1 as a rectangle, the shape of the first sub-area as a rectangular ring, and the shape of the second sub-area as a matrix ring as an example, the first section 421 can be arranged in the long side area or the short side area of ​​the first sub-area, and extend along the extension direction of the area in the long side area or the short side area of ​​the first sub-area. The second section 422 can be arranged at the connection between the long side area and the short side area of ​​the second sub-area.

[0105] In these optional embodiments, through the above configuration, the first section 421 and the second section 422 of the touch wiring 42 are respectively arranged in the first sub-area and the second sub-area, which is beneficial to increase the layout space of the touch wiring 42 while reducing the difficulty of preparing the touch wiring 42. Fig.12 for Figure 2 Another partial structural diagram of P.

[0106] like Fig.12 As shown, in some optional embodiments, the touch trace 42 includes a connecting segment 424 and a plurality of third segments 423, and two adjacent third segments 423 are connected by the connecting segment 424. The connecting segment 424 is extended along the edge of the orthographic projection of the first sub-support structure 211 on the substrate 10.

[0107] Exemplarily, the orthographic projection of the first sub-support structure 211 on the substrate 10 is a rectangle, and the orthographic projection of the connecting section 424 on the substrate 10 may be a folded line and extend along the edge of the first sub-support structure 211. Alternatively, the orthographic projection of the first sub-support structure 211 on the substrate 10 is a circle, and the orthographic projection of the connecting section 424 on the substrate 10 is an arc and extends along the edge of the first sub-support structure 211.

[0108] Optionally, the orthographic projection of the connecting section 424 on the substrate 10 may be arranged to overlap with the orthographic projection of the second sub-support structure 212 on the substrate 10. Of course, they may also be arranged to be non-overlapping.

[0109] In these optional embodiments, by providing the third segment 423 and the connecting segment 424 , the flexibility of the wiring of the touch wiring 42 can be improved, the space utilization of the second area A2 can be improved, and the overall area of ​​the second area A2 can be reduced.

[0110] like Fig.12 As shown, in some optional embodiments, the second area A2 further includes a binding area A21, in which the orthographic projection of the connecting segment 424 on the substrate 10 is located on the side of the orthographic projection of the first sub-support structure 211 on the substrate 10 facing away from the first area A1.

[0111] Optionally, the binding area A21 is disposed between the control chip IC and the first area A1.

[0112] It can be understood that, within the binding area A21, multiple touch lines 42 are arranged side by side, and the orthographic projection of the connecting segment 424 on the substrate 10 is located on the side of the orthographic projection of the first sub-support structure 211 on the substrate 10 that is away from the first area A1, so that one or several touch lines 42 on the side of the touch line 42 that is away from the first area A1 all have a connecting segment 424, and all have the same extension shape as the connecting segment 424 of the touch line 42 of the adjacent first sub-support structure 211, so as to improve the space utilization of the multiple touch lines 42 in the binding area A21.

[0113] Fig.13 and Fig.14 The thick solid line of the third segment 423, the thick solid line of the connecting segment 424, the thick solid line of the first sub-connecting segment 4241 and the thick solid line of the second sub-connecting segment 4242 are intended to reflect the different radial dimensions of the third segment 423, the connecting segment 424, the first sub-connecting segment 4241 and the second sub-connecting segment 4242.

[0114] Fig.13 for Figure 2 Another partial structural diagram of P.

[0115] like Fig.13As shown, in some optional embodiments, the touch trace 42 includes a connecting segment 424 and multiple third segments 423, and two adjacent third segments 423 are connected by the connecting segment 424; the orthographic projection of the connecting segment 424 on the substrate 10 at least partially overlaps with the orthographic projection of the first sub-support structure 211 on the substrate 10, and the radial dimension of the connecting segment 424 is greater than the radial dimension of the third segment 423.

[0116] In these optional embodiments, by setting the radial dimension of the connecting segment 424 to be larger than the radial dimension of the third segment 423, it is helpful to increase the contact area between the connecting segment 424 and the film layer below the connecting segment 424, thereby reducing the possibility of the connecting segment 424 being damaged or even broken due to the uneven film layer below the connecting segment 424. At the same time, the overall radial dimension of the touch wiring 42 can be reduced as much as possible, reducing the space occupied by the touch wiring 42 in the second area A2, and reducing the overall size of the second area A2.

[0117] Fig.14 for Figure 2 Another partial structural diagram of P.

[0118] like Fig.14 As shown, in some optional embodiments, the display panel 100 includes a mask area MK, and the mask area includes a corner area MK1. The second area A2 also includes a binding area A21, and the connecting segment 424 includes a first sub-connecting segment 4241 disposed in the corner area MK1 and a second sub-connecting segment 4242 disposed in the binding area A21, and the radial dimension of the first sub-connecting segment 4241 is greater than the radial dimension of the second sub-connecting segment 4242.

[0119] It can be understood that the touch lines 42 on the periphery of the first area A1 all extend through the binding area A21 and are electrically connected to the control chip IC located on the side of the binding area facing away from the first area A1. Setting the radial dimensions of the first sub-connection segment 4241 and the radial dimensions of the second sub-connection segment 4242 to be different is beneficial to reducing the space occupied by the second sub-connection segment 4242 in the binding area A21, while also improving the preparation yield of the touch lines 42.

[0120] Optionally, a radial dimension of the second sub-connecting segment 4242 is greater than a radial dimension of the third segment 423 .

[0121] Fig.15 for Figure 2 Another partial structural diagram of P.

[0122] like Fig.15 As shown, in some optional embodiments, the first sub-support structure 211 is disposed in the first area A1.

[0123] Optionally, the first sub-support structure 211 is only disposed in the first area A1 and is not disposed in the second area A2 , thereby reducing the influence of the first sub-support structure 211 on the touch wiring 42 in the second area A2 .

[0124] Figures 16 to 18 The thin solid lines and the thick solid lines of the first touch traces 425 are intended to reflect first touch traces 425 with different radial sizes among the plurality of first touch traces 425 .

The first touch line 425 extends from at least one side of the first area A1 opposite to the second direction Y and is connected to the control chip IC, and the first direction X and the second direction Y are arranged to intersect. The first touch line 425 includes a first group of touch lines L1 and a second group of touch lines L2, the first group of touch lines L1 includes the first first touch line L11 to the Mth first touch line L12, and the second group of touch lines L2 includes the M+1th first touch line L21 to the Nth first touch line L22, N≥2. The first touch line L11 is electrically connected to the first touch electrode 411 close to the control chip IC, and the orthographic projection of at least some of the first touch lines in the first group of touch lines L1 on the substrate 10 does not overlap with the orthographic projection of the first sub-support structure 211 on the substrate 10 .

[0127] Optionally, the plurality of first touch electrodes 411 are arranged in columns along the first direction X and in rows along the second direction Y. The first first touch trace L11 is electrically connected to the first touch electrode 411 close to the control chip IC, and can be understood as a first touch trace electrically connected to a row of first touch electrodes 411 adjacent to the control chip IC along the first direction X among the plurality of rows of first touch electrodes 411.

[0128] Optionally, the first group of touch lines L1 and the second group of touch lines L2 may be controlled in a time-sharing manner.

[0129] Optionally, the projections of all the first touch lines in the first group of touch lines L1 on the substrate 10 are arranged to be non-overlapping with the orthographic projection of the first sub-support structure 211 on the substrate. Alternatively, the projections of a portion of the first touch lines in the first group of touch lines L1 on the substrate 10 are arranged to be non-overlapping with the orthographic projection of the first sub-support structure 211 on the substrate.

[0130] Optionally, the projections of all the first touch lines in the second group of touch lines L2 on the substrate 10 are arranged to be non-overlapping with the orthographic projection of the first sub-support structure 211 on the substrate. Alternatively, the projections of a portion of the first touch lines among the plurality of first touch lines in the second group of touch lines L2 on the substrate 10 are arranged to be non-overlapping with the orthographic projection of the first sub-support structure 211 on the substrate.

[0131] In these optional embodiments, it is helpful to reduce the influence of the first sub-support structure 211 on the first touch control wiring and improve the manufacturing yield.

[0132] like Figure 2 As shown, in some optional embodiments, the first group of touch lines L1 and the second group of touch lines L2 are arranged on both sides of the first area A1 along the second direction Y. Or, as Fig.15 As shown, the odd-numbered first touch lines and the even-numbered first touch lines in the first group of touch lines L1 are arranged on both sides of the first area A1 along the second direction Y; the odd-numbered first touch lines and the even-numbered first touch lines in the second group of touch lines L2 are arranged on both sides of the first area A1 along the second direction Y.

[0133] In some embodiments, Figure 2 As shown, the first group of touch lines L1 and the second group of touch lines L2 are arranged on both sides of the first area A1 along the second direction Y, which helps to reduce the mutual interference between the two groups of touch lines 42, making the wiring more concise and orderly, and because the first group of touch lines L1 is closer to the control chip IC than the second group of touch lines L2, the extension length of the first touch lines in the two groups of touch lines 42 can be arranged in sequence according to a regular pattern, thereby improving the design accuracy of the first touch lines.

[0134] In some embodiments, Fig.15As shown, the odd-numbered first touch lines in the first group of touch lines L1 and the odd-numbered first touch lines in the second group of touch lines L2 may be located on the same side of the first area A1 along the first direction X; the even-numbered first touch lines in the first group of touch lines L1 and the even-numbered first touch lines in the second group of touch lines L2 may be located on the same side of the first area A1 along the first direction X. In other embodiments, the odd-numbered first touch lines in the first group of touch lines L1 and the even-numbered first touch lines in the second group of touch lines L2 may be located on the same side of the first area A1 along the first direction X; the even-numbered first touch lines in the first group of touch lines L1 and the odd-numbered first touch lines in the second group of touch lines L2 may be located on the same side of the first area A1 along the first direction X. In the above embodiments, different wiring schemes may be used for the first touch lines, thereby improving the wiring flexibility of the first touch lines and improving the design flexibility of the touch lines.

[0135] Fig.17 A schematic structural diagram of another display panel provided for some embodiments of the present application. Fig.18 A schematic structural diagram of another display panel provided for some embodiments of the present application.

[0136] like Fig.17 and Fig.18 As shown, in some optional embodiments, the radial dimension of at least part of at least part of the first touch lines in the first group of touch lines L1 is smaller than the radial dimension of the second group of touch lines L2.

[0137] In some embodiments, Fig.17 As shown, the radial dimension of the first touch line in the first group of touch lines L1 is smaller than the radial dimension of the first touch line in the second group of touch lines L2. Fig.17 As shown, the radial dimension of the first touch line in the first group of touch lines L1 close to the second group of touch lines L2 is the same as the radial dimension of the first touch line in the second group of touch lines L2, and the radial dimension of the first touch line in the first touch line far from the second group of touch lines L2 is smaller than the radial dimension of the first touch line in the second group of touch lines L2.

[0138] It can be understood that the distance between the first group of touch lines L1 and the control chip IC is smaller than the distance between the second group of touch lines L2 and the control chip IC, so that the extension length of the first group of touch lines L1 is smaller than the extension length of the second group of touch lines L2. When the radial dimension of the first group of touch lines L1 is the same as the radial dimension of the second group of touch lines L2, the resistance of the first group of touch lines L1 is smaller than the resistance of the second group of touch lines L2. In the embodiment of the present application, the radial dimension of the first group of touch lines L1 is set to be smaller than the radial dimension of the second group of touch lines L2 to increase the cross-sectional area of ​​the second group of touch lines L2, thereby reducing the resistance of the second group of touch lines 42, so that the resistance of the first group of touch lines L1 is the same as the resistance of the second group of touch lines L2, thereby reducing the influence of resistance on touch signals and improving touch performance.

[0139] Fig.19 A schematic cross-sectional structure diagram of another display panel provided in some embodiments of the present application.

[0140] like Fig.19 As shown, in some optional embodiments, the touch layer 40 includes a first conductive layer M1 and a second conductive layer M2 sequentially arranged in a direction away from the substrate 10, and the touch trace 42 includes a first conductive portion M11 arranged in the first conductive layer M1 and a second conductive portion M21 arranged in the second conductive layer M2. In the orthographic projection of the substrate 10, the first conductive portion M11 and the second conductive portion M21 are at least partially overlapped. The radial dimension of at least part of the first conductive portion M11 is greater than the radial dimension of the second conductive portion M21.

[0141] Optionally, the first touch control trace 425 includes a first conductive layer M1 and a second conductive layer M2.

[0142] Optionally, the second touch-control trace 426 includes a first conductive layer M1 and a second conductive layer M2.

[0143] In some embodiments, the orthographic projection of the first conductive portion M11 on the substrate 10 and the orthographic projection of the second conductive portion M21 on the substrate partially overlap.

[0144] In combination with the above embodiment, the radial dimension of at least part of the first conductive part M11 is greater than the radial dimension of the second conductive part M21. It can be understood that the radial dimension of the first conductive part M11 of the third segment 423 and the radial dimension of the second conductive part M21 of the third segment 423 can be the same, or of course, can be different. For example, the radial dimension of the first conductive part M11 of the third segment 423 is greater than the radial dimension of the second conductive part M21 of the third segment 423. The radial dimension of the first conductive part M11 of the connecting segment 424 is greater than the radial dimension of the second conductive part M21 of the connecting segment 424, and the orthographic projection of the first conductive part M11 on the substrate 10 overlaps with the orthographic projection of the first sub-support structure 211 on the substrate.

[0145] In these optional embodiments, by setting the radial dimension of the first conductive part M11 and the radial dimension of the second conductive part M21 to be different, since the first conductive part M11 is located between the support structure 21 and the second conductive part M21, the radial dimension of the first conductive part M11 is increased, thereby reducing the risk of cracking or even breaking of the first conductive part M11 due to the unevenness of the underlying film layer. The small radial dimension of the second conductive part M21 is beneficial to reducing the space occupied by the second conductive part in the second area A2, thereby reducing the overall size of the second area.
