[0002] With the development of display technologies, flexible display panels are increasingly commonly used in the market, such as fixed curved screens, flexible foldable screens, flexible sliding screens, flexible curling screens, etc. When they are bent / folded, local areas are repeatedly stressed. If the stress cannot be released in time, it will cause damage to the circuit or failure of the encapsulation, resulting in poor display. Summary of the Invention

[0003] The purpose of this application is to provide a display panel and a display device to solve the problem that in existing flexible display panels, the stress in local areas cannot be released in time, resulting in damage to the circuit inside the display panel or failure of the encapsulation, leading to poor display.

[0004] To achieve the above purpose, this application adopts the following technical solutions:

[0005] A display panel, which includes:

[0006] A light-emitting layer;

[0007] A touch layer, the touch layer includes a first touch trace layer;

[0008] The first touch trace layer includes a plurality of first touch signal units, and the plurality of first touch signal units have ends;

[0009] At least some of the ends have stress relief portions, and the projection of the stress relief portions on the side of the light-emitting layer does not contact the pixel openings corresponding to the pixels in the light-emitting layer. By setting the stress relief portions, it is avoided that the stress after being stressed at this place cannot be released in time and acts on the thin film encapsulation layer on its lower side, resulting in fracture / cracking of the thin film encapsulation layer and further causing poor display.

[0010] In an embodiment, the plurality of first touch signal units are arranged in an array, and at least some of the plurality of adjacent two first touch signal units include at least one pair of opposite ends,

[0011] A pair of opposite ends includes a first end and a second end,

[0012] The first end is located in one of the first touch signal units, the second end is located in another first touch signal unit, and there is a gap between the opposite first end and the second end;

[0013] Preferably, the distance between the opposite first end and the second end is greater than or equal to 2 μm;

[0014] Preferably, it includes a thin film encapsulation layer, which is located between the light-emitting layer and the touch layer.

[0015] In one embodiment, the stress relief portion of a second end in a set of opposite ends is at least partially C-shaped, U-shaped or Y-shaped, and its opening faces the first end;

[0016] Preferably, the first end in a set of opposite ends extends into the opening of the stress relief portion;

[0017] Preferably, the first end in a set of opposite ends extends into the opening of the stress relief portion, and the shape of the first end located within the opening is arc-shaped towards the opening.

[0018] In one embodiment, each first touch signal unit includes at least one first end and at least one second end, wherein the end of the first end is arc-shaped; the second end has a stress relief portion, and the stress relief portion is at least partially C-shaped, U-shaped or Y-shaped.

[0019] In one embodiment, the touch layer includes an organic layer, which is laminated on the first touch trace layer.

[0020] Furthermore, the side of the organic layer away from the first touch trace layer has a plurality of depressions, and the projection of the depressions on the plane where the first touch trace layer is located falls between the opposite first end and second end.

[0021] In one embodiment, in the projection on the plane where the first touch trace layer is located, the shape of the depression matches the shape of the stress relief portion or the shape of the depression is the same as the shape of the stress relief portion.

[0022] In one embodiment, the display panel further includes a cover plate, and the cover plate is attached to the side of the organic layer away from the light-emitting layer.

[0023] An embodiment of the present application provides a display device, which includes the above-mentioned display panel.

[0024] Advantages of the present invention: The display panel provided by the present application improves the wiring structure of the touch signal lines in the touch layer. Specifically, a stress relief portion is provided at the end of the first touch signal unit to avoid poor display caused by the stress at this position not being released in time after being stressed, resulting in the fracture / cracking of the thin film encapsulation layer.

[0025] In addition, adjust the setting position of the stress release part to avoid the pixel openings on its lower side (that is, the projection of the stress release part on the light-emitting layer side does not contact the pixel openings corresponding to the pixels in the light-emitting layer), so as not to affect the outgoing light of the pixels in the light-emitting layer. Through the structural optimization of the organic layer (such as the OC organic layer) on the first touch trace layer in the touch layer, there are a plurality of depressions on the side of the OC organic layer far from the first touch trace layer. The depressions face the distance between opposite ends (such as the distance between a set of opposite ends). After attaching the cover plate, the combination of the depressions and the cover plate forms a cavity. When the display panel is bent or folded, the organic glue between the opposite ends deforms, and the shape of the cavity deforms synchronously. The cavity plays a buffering role to release stress, thereby reducing stress concentration, and further avoiding display defects caused by the film encapsulation layer being broken / cracked due to the stress not being released in time.

[0034] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings to prove that the present invention can be implemented. The embodiments of the invention can fully introduce the present invention to those skilled in the art, making its technical content clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and the protection scope of the present invention is not limited to the embodiments mentioned in the text.

[0035] In the drawings, components with the same structure are denoted by the same reference numerals, and components with similar structures or functions everywhere are denoted by similar reference numerals. The size and thickness of each component shown in the drawings are arbitrarily shown, and the present invention does not limit the size and thickness of each component. To make the illustration clearer, the thickness of some components in the drawings is appropriately exaggerated.

[0036] In addition, the following descriptions of the embodiments of the invention refer to the attached drawings to illustrate specific embodiments in which the present invention can be implemented. Directional terms mentioned in the present invention, such as "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "side", etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are for better and clearer description and understanding of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and thus cannot be construed as a limitation of the present invention. In addition, terms such as "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0037] When some components are described as "on" another component, the component can be directly placed on the other component; there can also be an intermediate component, the component is placed on the intermediate component, and the intermediate component is placed on another component. When a component is described as "mounted to" or "connected to" another component, the two can be understood as directly "mounted" or "connected", or a component is indirectly "mounted to" or "connected to" another component through an intermediate component.

[0038] Flexible folding screens, flexible sliding screens, etc. are collectively referred to as flexible display panels / display panels, which include stacked substrates, light-emitting layers, TFE encapsulation layers (thin film encapsulation layers), polarizing layers, touch layers, and cover plates. When assembled or in actual use, the display panel can be bent / folded, and compared with traditional rigid display panels, it has the characteristics of being thin, bendable, impact-resistant, and easy to carry.

[0039] When the display panel is bent / folded, each film layer has bending tension, and local areas are repeatedly stressed. If the stress cannot be released in time, the materials between the bonding interfaces / joints will slip and delaminate from each other, resulting in a risk of material fracture and causing display defects. The stress also acts on the thin film encapsulation layer on its lower side, causing the thin film encapsulation layer to break / crack and further causing display defects.

[0040] The applicant further analyzed the structure of the touch layer, also known as the TP film layer. The TP film layer includes a first touch trace layer, an insulating layer, and a second touch trace layer. The first touch trace layer includes a plurality of first touch signal units 121, and the second touch trace layer includes a plurality of second touch signal units 122. In the current structure of the TP film layer, as Figure 1 shown, it includes a plurality of first touch signal units 121. The combination of the first touch signal units is arranged in a grid pattern. At least one grid-corresponding first touch signal unit includes at least one set of ends, namely a first end 121a and a second end 121b. The first end 121a and the second end 121b are arranged opposite to each other with a spacing c therebetween. The first touch trace layer and the second touch trace layer are stacked as Figure 1a shown. The second touch signal unit 122 is bridged to the corresponding second touch signal unit 122 through a wire-changing hole. An insulating layer is provided between the first touch trace layer and the second touch trace layer. After the display panel is bent / folded multiple times, display defects caused by flexible package failure are likely to occur. The applicant found that most of the flexible package failure defects occur at the ends.

[0041] Based on this discovery, the applicant improved the display panel.

[0042] The applicant proposed a display panel.

[0043] The display panel includes a light-emitting layer and a touch layer. The touch layer includes a first touch trace layer. The first touch trace layer includes a plurality of first touch signal units, and at least some of the plurality of first touch signal units have ends. At least some of the ends have stress relief portions, and the orthographic projection of the stress relief portion on the light-emitting layer does not contact the pixel opening corresponding to the pixel in the light-emitting layer (i.e., does not block the outgoing light of the light-emitting layer). The TP film layer in this embodiment can be a self-capacitive TP film layer or a mutual-capacitive TP film layer. For the convenience of understanding, the mutual-capacitive TP film layer will be taken as an example for subsequent description.

[0044] In this embodiment, the first touch signal units are arranged in an array, and their combination forms a mesh. Preferably, the contour of the area where the first touch signal units are located is square / rhombus, which can match multiple pixel openings. Each first touch signal unit includes at least one pair of opposite ends (such as 2 pairs of opposite ends), and there is a gap between the opposite ends (the projections of the opposite ends on the light-emitting layer side do not touch), and this gap is used to separate the electrical connections between adjacent rows / columns (to identify the triggered position when triggered). By improving the wiring of the first touch signal units of the touch layer (TP film layer) and optimizing the structure of their ends, it is avoided that the stress at this place cannot be released in time after being stressed, and the stress concentration acts on the thin film encapsulation layer, resulting in increased stress on the thin film encapsulation layer (TFE film layer) and causing display defects such as fracture / cracking. The thin film encapsulation layer is located between the light-emitting layer and the touch layer. The thin film encapsulation layer is used to seal the light-emitting layer.

[0045] A touch layer, the touch layer includes a first touch wiring layer, the first touch wiring layer includes a plurality of first touch signal units, and at least some of the plurality of first touch signal units have ends, at least some of the ends have stress relief portions, and the orthographic projection of the stress relief portion on the light-emitting layer does not contact the pixel openings corresponding to the pixels in the light-emitting layer (that is, does not block the outgoing light of the light-emitting layer).

[0046] Next, the display panel and the display device proposed by this application will be described in detail with reference to the accompanying drawings.

[0047] As Figure 2 Shown is a schematic structural diagram of the display panel of this embodiment. The display panel 100 can be bent or folded and has a display area 110. A touch layer is provided on the display panel 100, and a cover plate is attached to the touch layer (close to the user side during use).

[0048] Figure 3 It is a schematic wiring diagram of the first touch signal units of the first touch wiring layer in the improved TP film layer.

[0049] The first touch wiring layer includes a plurality of first touch signal units 221. The plurality of first touch signal units 221 are arranged in an array, and the combination of the plurality of first touch signal units 221 is generally arranged in a grid shape, that is, the orthographic projection of the plurality of first touch signal units 221 on the cover plate is generally in a grid shape.

[0050] At least two adjacent first touch signal units 221 each include at least one set of opposite ends. One set of ends includes a first end 221a and a second end 221b (the first end 221a and the second end 221b are oppositely arranged), the first end is located in one of the first touch signal units, the second end 221b is located in the other first touch signal unit 221, and there is a gap between the opposite first end 221a and the second end 221b; Exemplarily, the distance between the first end and the second end is greater than or equal to 2 μm (this distance can be 2.8 μm, 3 μm, 3.5 μm, 4.6 μm, 5 μm, 6.2 μm, 7.3 μm, 8.8 μm, 9 μm or 10 μm, etc.).

[0051] Further, one end of a set of ends has a stress relief portion. The first end 221a and the second end 221b are oppositely arranged, and the second end 221b has a stress relief portion (the stress relief portion is in a C shape or a U shape or a Y shape or at least partially in a C shape or a U shape or a Y shape), and its opening (such as the C shape, the U shape, and the Y shape have an unclosed area) faces the first end 221a (the first end 221a and the second end 221b are in a nested combination). By improving the structure of the ends, the stress concentration at the ends of the display panel after bending or folding is reduced, and the display defect caused by the stress at this place not being released in time, resulting in an increase in the force on the thin film encapsulation layer (TFE film layer) and causing fracture / breakage is avoided. Preferably, a stress relief portion can also be provided at the first end to reduce the stress concentration at the end and avoid the display defect caused by the stress not being released in time, resulting in an increase in the force on the thin film encapsulation layer (TFE film layer) and causing fracture / breakage. In this embodiment, the end of the first end 221a is rounded. Preferably, the stress relief portion is integrally designed with the first touch signal unit (such as obtained by patterning and etching). In this embodiment, multiple first touch signal units are arranged in a substantially grid pattern, and their electrical connection with the first touch signal units in adjacent rows / columns is separated by the distance between the ends. By improving the structure of the ends, the stress is released in time to avoid the display defect caused by it. In this embodiment, by rounding one end of a set of ends and providing a stress relief portion at the other end, the stress concentration at the bending / folding is reduced. In other embodiments, stress relief portions can also be provided at both ends of a set of ends. Preferably, the first end in a set of opposite ends extends into the opening of the stress relief portion, or, the first end in a set of opposite ends extends into the opening of the stress relief portion, and the shape of the first end located in the opening is arc-shaped towards the opening.

[0052] It should be noted that in this embodiment, each first touch signal unit includes at least one first end and at least one second end, that is, at least one first end and at least one second end are provided on each touch signal unit. Further, the end of the first end is arc-shaped; the second end has a stress relief portion, and at least a part of the stress relief portion is in a C shape, a U shape or a Y shape.

[0053] For further improvement of the embodiment, please refer to Figure 3 and Figure 4 When there is an organic layer (OC organic layer) on the first touch trace layer, when setting the OC organic layer, OC organic glue (such as OC optical glue) can be coated first, and part of the OC organic glue fills the gap between the first end 221a and the second end 221b, and a halftone mask (Half-Tone Mask, HTM) is used for image design. The obtained OC organic layer 323 is as Figure 5 shown, and it has a depression 323a at the position corresponding to the gap between the first end 221a and the second end 221b of the first touch signal unit. The advantage of such a design is that after a cover plate 330 is attached thereto, the combination of the depression 323a of the OC organic layer 323 and the cover plate 330 forms a cavity, which can release stress. When the display panel is bent or folded, the OC organic glue deformation between the first end 221a and the second end 221b (the shape of the cavity deforms synchronously, playing a buffering role) can release stress. This method improves the structure of the cured OC organic layer to further release stress in a timely manner. Figure 4 Preferably, in an embodiment, the depth of the depression in the thickness direction is the same as or substantially the same as the thickness of the first touch signal unit. Preferably, the shape of the depression is the same as the shape of the stress relief portion of the first / second end. In this embodiment, the first touch signal unit is disposed on the buffer layer 325 through the insulating layer 324.

[0054] Preferably, in an embodiment, the projection of the depression on the side of the first touch trace layer falls between the first end 221a and the second end 221b (the width of the depression in the x direction is less than or equal to the interval between the first end and the second end).

[0055]

[0056] Figure 4 As a Figure 5 variant of the embodiment, the depression structure on the OC organic layer can be disposed at the gap between the first end and the second end as shown in Figure 3 The combination of the depression and the cover plate forms a cavity, and when the display panel is bent or folded, the cavity deforms to release stress.

[0057] ​​In some specific embodiments, the TP film layer includes a first touch wiring layer, an insulating layer, and a second touch wiring layer. Among them, the second touch wiring layer is disposed on a side of the insulating layer away from the first touch wiring layer. A substrate is provided on a side of the second touch wiring layer away from the insulating layer. The substrate can be made of PI material, optical glue, CPI material, or PET material. An optical glue layer is provided on a side of the first touch wiring layer away from the insulating layer. During production, usually a layer of liquid optical glue is coated first, and part of the optical glue flows and fills the gap between the first end and the second end which is greater than or equal to 2 μm (this gap can be 2.8 μm, 3 μm, 3.5 μm, 4.6 μm, 5 μm, 6.2 μm, 7.3 μm, 8.8 μm, 9 μm, 10 μm, etc.), and then the optical glue layer is prepared by curing through methods such as UV irradiation or exposure.

[0058] In an embodiment of the present invention, a display device is further provided. The display device can be an OLED (organic electroluminescence) display device, which includes the above-mentioned display panel. The display device can be any display device with a display function, such as a mobile phone, a tablet computer, etc.

[0059] In one embodiment, a cross-sectional schematic of the display device is as Figure 6 shown, including a stacked substrate 350, a light-emitting layer 340, a TFE encapsulation layer 310, a touch layer 320, and a cover plate 330. In subsequent module processes, a foam is provided on a side of the substrate away from the light-emitting layer to reduce the buffering force on the display panel during falling or other movements, so as to protect the display panel, and its thickness is between 80 and 130 μm.

[0060] The cover plate is made of a foldable plastic layer, and in some cases, glass is used, such as in fixed curved / surface occasions.

[0061] The substrate can be PI (polyimide), on which a pixel driving circuit is provided. The pixel driving circuit is electrically connected to the pixel units / pixels in the corresponding light-emitting layer in the light-emitting layer, and based on the pixel driving circuit, the corresponding pixel units / pixels are driven to emit light. The driving circuit can be a 7T1C, 7T2C, 8T1C circuit, which is not limited herein.

[0062] Preferably, the display device includes a barrier film, which is disposed on the TFE encapsulation layer 310. Preferably, the display device includes a polarizing layer, which is disposed above or below the touch layer 320.

[0063] The polarizing layer has a thickness of 143 to 170 μm and generally consists of a linear polarizer and a quarter wave plate. The quarter wave plate is generally made of COP material, which is difficult to reduce in thickness. In addition, the COP material is very brittle and easily breaks when bent. A coated polarizer can be used, which is prepared using a coating process to achieve the functions of linear polarization and a quarter wave plate, while ensuring that the coating layer generally does not exceed 10 μm.

[0064] The barrier film is used to prevent the light emitting device from being affected by water and oxygen to block water and oxygen. The thickness of the barrier film is between 50 and 150 μm. In other embodiments, the barrier film can be omitted.

[0065] The touch layer is arranged on the polarizer layer through an optical adhesive (OCA). The cover plate is arranged on the side of the touch layer away from the polarizer layer through an optical adhesive (OCA) layer. OCA (Optical Clear Adhesive) is mainly used for bonding between module materials or between materials and the screen body, and its thickness is between 25 and 100 microns. Preferably, the neutral layer of the display panel / display device can be adjusted to the light-emitting layer by adjusting the thickness of the optical adhesive. Preferably, the metal circuits of the light-emitting layer and the touch layer are adjusted to the neutral layer to minimize the tensile stress and compressive stress received by the display panel (the neutral layer, also called the neutral axis, refers to the intersection of the neutral layer and the cross section of the beam. In the case of plane bending and oblique bending, the positive stress values ​​of each point on the intersection of the cross section and the stress plane are zero, and this intersection is called the neutral axis. In the case of plane bending and oblique bending, the positive stress values ​​of each point on the intersection of the cross section and the stress plane are zero, and this intersection is called the neutral axis. During deformation, the cross section will rotate around the neutral axis. The plane formed by the neutral axes of all cross sections is called the neutral plane).

[0066] The touch layer (TP film layer) includes a first touch wiring layer, an insulating layer and a second touch wiring layer. The second touch wiring layer is close to the TFE packaging layer. The first touch wiring layer includes multiple first touch signal units. The combination of the multiple first touch signal units is arranged in a grid shape. The first touch signal unit has an end. By optimizing the structure of the end, a stress release part is set. Through such a setting, stress concentration at the end during bending / folding is avoided, and stress cannot be released in time, resulting in increased stress on the thin film packaging layer (TFE film layer), breakage / rupture, and then causing poor display.

[0067] The stress release portion is at least partially C-shaped, U-shaped or Y-shaped, and the opening is toward the other end, and the concentration of stress on the TP end is avoided by such an arrangement. In one embodiment, the end includes a chamfer. The stress release portion avoids the pixel opening area of ​​the pixel below it, so as not to affect the outgoing light of the pixel.

[0068] The touch layer further includes a base layer, which can be made of PI material or PET (Polyethylene terephthalate) material. When the base is made of PI material, the TP film layer is disposed on the barrier film or the TFE encapsulation layer through an optical adhesive. When the base is made of PET material, it is laminated on the polarizer layer, and the polarizer layer is disposed on the barrier film or the TFE encapsulation layer through an optical adhesive.

[0069] In one embodiment, an organic adhesive (OC optical adhesive) is disposed on the first touch trace layer and connected to the cover plate or the polarizer layer through it.
