[0001] The present application claims priority to the Chinese patent application No. 202410841655.5, filed on June 26, 2024, and entitled "Display module and display device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of display, in particular to a display module and a display device. BACKGROUND

[0003] The non-display area of the display panel includes a bending area and a binding area, wherein the bending area is bent towards the back side of the display area to place the binding area on the back light side. However, in this way, the bending part is close to the middle frame antenna, and the signal interference between the metal line in the bending area and the middle frame antenna is large, thereby causing serious signal interference problems of the whole machine.

[0004] SUMMARY

[0005] Therefore, the embodiments of the present application provide a display module and a display device to reduce the signal interference between the metal line in the bending area and the middle frame antenna.

[0006] In one aspect, the embodiments of the present application provide a display module, comprising:

[0007] A display panel, comprising a display area, a bending area and a binding area, wherein the bending area is bent towards the back light side of the display area, and the binding area is located on the back light side of the display area; further comprising a substrate and a first trace, wherein the first trace is located at least in the bending area;

[0008] A shielding layer, located at least in the bending area and on the side of the first trace away from the substrate.

[0009] In another aspect, the embodiments of the present application provide a display device, comprising the above display module.

[0010] One of the above technical solutions has the following beneficial effects:

[0011] In the display module provided by the embodiment of the present application, the shielding layer is arranged on the side of the first trace away from the substrate, so that the shielding layer is arranged between the first trace in the bending area and the middle frame antenna of the whole machine, thereby shielding or absorbing the signals, such as electromagnetic waves, radiated outward by the two respectively. In this way, even if the bending part of the display panel is relatively close to the middle frame antenna after being bent, the mutual signal interference between the first trace in the bending area and the middle frame antenna can be effectively reduced, the signal interference problem of the whole machine can be effectively improved, and the performance of the whole machine is improved. The technical solution is especially suitable for the display panel with a narrow frame. In such a display panel, the lower frame width needs to be compressed to be smaller, so that the bending part of the display panel is relatively close to the middle frame antenna, and the signal interference problem is more serious. However, after the above technical solution is applied, the problem can be effectively solved. BRIEF DESCRIPTION OF DRAWINGS

[0036] In order to better understand the technical solutions of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0037] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0038] The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the description of the application and the appended claims, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0039] It should be understood that the term "and / or" used herein only describes an association relationship of associated objects, which means that there can be three relationships, for example, A and / or B, which can represent three cases of A existing alone, A and B existing together, and B existing alone. In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects.

[0040] Embodiments of the present application provide a display module, as shown in FIGS. 1-3, FIG. 1 is a structural schematic diagram of a display module provided by an embodiment of the present application, FIG. 2 is a partial structural schematic diagram of a display module provided by an embodiment of the present application, and FIG. 3 is a schematic diagram of a display panel 1 in a flat state provided by an embodiment of the present application. The display module includes the display panel 1, which can be specifically an organic light emitting diode (OLED) display panel or other types of display panel. The display panel 1 includes a display area 2, a bending area 3, and a binding area 4. The bending area 3 is bent towards the backlight side of the display area 2 to place the binding area 4 on the backlight side; and the binding area 4 is used to bind a driving chip, a printed circuit board, and the like.

[0041] Referring to FIGS. 2 and 3, the display panel 1 further includes a substrate 5 and a first trace 6, and the first trace 6 is located at least in the bending area 3. It can be understood that the display area 2 is provided with various display signal lines 7 such as data lines and power signal lines for driving sub-pixels to emit light normally. The first trace 6 is electrically connected with the display signal lines 7, and is used to transmit signals provided by the driving chip or the printed circuit board to the various display signal lines 7. The first trace 6 can specifically include data connection signal lines electrically connected with the data lines, and power buses electrically connected with the power signal lines, and the like.

[0042] In addition, it also needs to be explained that in the film layer structure schematic diagram of the display panel 1 shown in the embodiments of the present application, only the first trace 6 is simply shown to be located in a certain metal layer, but in actual application, different first traces 6 can be respectively located in different metal layers, or a single first trace 6 can also be provided across at least two metal layers, which is not limited by the present application.

[0043] The display module further includes a shielding layer 8, and the shielding layer 8 is located at least in the bending area 3 and on a side of the first trace 6 away from the substrate 5. The shielding layer 8 can include a material for shielding or absorbing electromagnetic waves.

[0044] In the display module provided by the embodiment of the present application, the shielding layer 8 is arranged on the side of the first trace 6 away from the substrate 5, and the shielding layer 8 is arranged between the first trace 6 in the bending area 3 and the middle frame antenna 9 of the whole machine, thereby shielding or absorbing the signals, such as electromagnetic waves, radiated outward by the first trace 6 and the middle frame antenna 9. In this way, even if the bending part of the display panel 1 is close to the middle frame antenna 9 after being bent, the mutual signal interference between the first trace 6 in the bending area 3 and the middle frame antenna 9 can be effectively reduced, the signal interference problem of the whole machine can be effectively improved, and the performance of the whole machine is improved. The technical solution is particularly suitable for a display panel with a narrow frame. In such a display panel, the lower frame width needs to be compressed to be smaller, so that the bending part of the display panel 1 is closer to the middle frame antenna 9, and the signal interference problem is more serious. However, after the above technical solution is applied, the problem can be effectively solved.

[0045] In a feasible embodiment, as shown in FIG. 4 and FIG. 5, FIG. 4 is another structural schematic diagram of the display module provided by the embodiment of the present application, and FIG. 5 is a schematic diagram of a film layer structure of the display module provided by the embodiment of the present application in the flat state. The display panel 1 includes a first film layer 10, which is the film layer farthest from the substrate 5. The shielding layer 8 includes a first shielding layer 11, which is located on the side of the first film layer 10 away from the substrate 5.

[0046] More specifically, referring to FIG. 5, the display panel 1 can further include a circuit layer 12 and a light emitting device layer 13 located on the side of the circuit layer 12 away from the substrate 5. The circuit layer 12 includes structures such as transistors 14, and at least part of the first trace 6 can also be located in the circuit layer 12. The light emitting device layer 13 includes light emitting elements 15. The first film layer 10 is located on the side of the light emitting device layer 13 away from the circuit layer 12, and is the outermost film layer of the display panel 1, for example, can be an encapsulation layer.

[0047] This kind of arrangement is to arrange the first shielding layer 11 on the outside of the display panel 1. While solving the signal interference between the first trace 6 and the middle frame antenna 9 by using the first shielding layer 11, the first shielding layer 11 will not affect the original process of other film layers in the display panel 1. That is, in the process of the display module, the circuit layer 12, the light emitting device layer 13 and the first film layer 10 in the display panel 1 are all made according to the original process, and then the first shielding layer 11 is formed on the outside of the display panel 1 after the display panel 1 is made.

[0048] Further, the first shielding layer 11 is disposed outside the film layer of the display panel 1, and the material selection range of the first shielding layer 11 is wider. For example, the first shielding layer 11 can include a sticky material having a shielding or absorbing electromagnetic wave function. Before the display panel 1 is bent, the sticky material is directly coated on the surface of the first film layer 10, and after the display panel 1 is bent, the distribution of the shielding material in the bending area 3 can be as uniform as possible. Alternatively, the first shielding layer 11 can also include a non-sticky material having a shielding or absorbing electromagnetic wave function. At this time, the shielding film can be adhered to the outside of the first film layer 10 through a glue layer.

[0049] Further, as shown in FIGS. 6 and 7, FIG. 6 is another structural schematic diagram of the display module provided by the embodiment of the present application, and FIG. 7 is a structural schematic diagram of the display module corresponding to FIG. 6 in a flat state. The display module further includes a bending protection layer (BPL) 16 located on one side of the display panel 1 and at least in the bending area 3. The bending protection layer 16 can include a material such as a polymer resin or polyimide. On the one hand, the bending protection layer 16 is used to protect the bent substrate 5 from external impact and to support the substrate 5, so that the substrate 5 can still maintain a good shape after bending. On the other hand, the bending protection layer 16 is also used to balance the bending stress in the bending area 3 and reduce the risk of fracture of the metal trace in the bending area 3 due to stress concentration.

[0050] The first shielding layer 11 includes a first sub-shielding layer 17 located on the side of the bending protection layer 16 away from the display panel 1.

[0051] Generally, in the overall structure, there is a part of blank space between the bending protection layer 16 and the middle frame. The shielding film layer disposed outside the bending protection layer 16 can realize the reasonable use of the blank space, and the design of the shielding film layer structure is less limited in this setting area. For example, referring to FIG. 6, the first sub-shielding layer 17 can be directly attached to the surface of the bending protection layer 16, or, as shown in FIG. 8, another structural schematic diagram of the display module provided by the embodiment of the present application, the first sub-shielding layer 17 can be selected to be fixedly connected to the cover plate 18 at one end and fixedly connected to the frame 19 at the other end, and has a certain interval with the bending protection layer 16, so that the first sub-shielding layer 17 can have more diversified structural design. In addition, the design of the size of the first sub-shielding layer 17 is less limited in this setting area. For example, the first sub-shielding layer 17 can have a larger thickness to further improve the shielding performance.

[0052] And / or, as shown in FIG. 9 and FIG. 10, FIG. 9 is a schematic view of another structure of the display module provided by the embodiment of the present application, and FIG. 10 is a schematic view of another structure of the display module in the flat state corresponding to FIG. 9. The first shielding layer 11 comprises a second shielding sub-layer 20, and the second shielding sub-layer 20 is located between the bending protection layer 16 and the display panel 1.

[0053] In the above setting mode, the second shielding sub-layer 20 is formed on the surface of the display panel 1 first, and then the bending protection layer 16 is formed. Since the bending protection layer 16 can balance the stress center layer, the bending protection layer 16 can play a certain protective role on the second shielding sub-layer 20, reduce the influence of stress on the second shielding sub-layer 20, prevent the second shielding sub-layer 20 from generating cracks due to stress concentration when bending, and improve the reliability of the second shielding sub-layer 20.

[0054] In a feasible implementation, as shown in FIG. 11, the display module further comprises a polarizer 21 and a cover plate 18. The polarizer 21 is located at least in the display area 2 and on one side of the display panel 1, and the cover plate 18 is located on the side of the polarizer 21 away from the display panel 1. The polarizer 21 and the cover plate 18 can be bonded together through an optical adhesive layer 22.

[0055] In the above setting mode, the second shielding sub-layer 20 is formed on the surface of the display panel 1 first, and then the bending protection layer 16 is formed. Since the bending protection layer 16 can balance the stress center layer, the bending protection layer 16 can play a certain protective role on the second shielding sub-layer 20, reduce the influence of stress on the second shielding sub-layer 20, prevent the second shielding sub-layer 20 from generating cracks due to stress concentration when bending, and improve the reliability of the second shielding sub-layer 20.

[0056] Based on the above setting mode, when the first shielding layer 11 is located inside the bending protection layer 16, the end of the first shielding layer 11 close to the display area 2 does not overlap the polarizer 21, which can avoid the first shielding layer 11 from blocking the light emitted from the display panel 1 and entering the polarizer 21. When the first shielding layer 11 is located outside the bending protection layer 16, the end of the first shielding layer 11 close to the display area 2 does not overlap the polarizer 21, which can avoid the first shielding layer 11 from blocking the light emitted from the display panel 1 and entering the polarizer 21. Therefore, this structure can avoid the first shielding layer 11 from affecting the normal light emission of the display module, and ensure good display effect.

[0057] Further, referring again to FIG. 11, the distance d1 between the end of the first shielding layer 11 close to the display area 2 and the projection of the polarizer 21 on the cover plate 18 is greater than 0.2 mm.

[0058] This numerical range covers the process error. Even if the positions of the first shielding layer 11 and the polarizer 21 deviate due to process error and other factors, the end of the first shielding layer 11 close to the display area 2 can still avoid overlapping the polarizer 21.

[0059] In an embodiment, as shown in FIGS. 12 and 13, FIG. 12 is another schematic view of the film structure of the display module in a flat state, and FIG. 13 is another schematic view of the structure of the display module. The display panel 1 further includes a circuit layer 12 and a light-emitting device layer 13. The circuit layer 12 includes a transistor 14 and the first wiring 6. The light-emitting device layer 13 is located on the side of the circuit layer 12 away from the substrate 5 and includes a light-emitting element 15.

[0060] The shielding layer 8 includes a second shielding layer 23. The second shielding layer 23 includes a metal material and is located between the circuit layer 12 and the light-emitting device layer 13.

[0061] The second shielding layer 23 in this structure can include a metal material and can be formed by plating and etching after the circuit layer 12 is formed. For example, the second shielding layer 23 can include only one metal material or can include an alloy material, such as at least one of aluminum, titanium, and copper.

[0062] When the second shielding layer 23 is a metal shielding film, it is selected to be located between the circuit layer 12 and the light-emitting device layer 13. On the one hand, the second shielding layer 23 does not affect the original process of the circuit layer 12. On the other hand, the second shielding layer 23 does not occupy the wiring space of other metal wires in the circuit layer 12. In other words, the second shielding layer 23 and the wiring of other metal wires in the circuit layer 12 do not affect each other. Therefore, the size of the second shielding layer 23 can be more flexibly designed, such as having a larger film thickness or a larger wiring area.

[0063] Further, as shown in FIG. 14, the display module further includes a polarizer 21 and a cover plate 18. The polarizer 21 is located at least in the display area 2 and on one side of the display panel 1. The cover plate 18 is located on the side of the polarizer 21 away from the display panel 1.

[0064] The end of the second shielding layer 23 near the display area 2 is projected on the cover plate 18 and overlaps the projection of the polarizer 21 on the cover plate 18.

[0065] Because the second shielding layer 23 is located inside the film layer of the display panel 1 and on the side of the light-emitting device layer 13 close to the substrate 5, the second shielding layer 23 does not affect the light emission of the light-emitting device layer 13. Therefore, the end of the second shielding layer 23 near the display area 2 can be arranged to overlap the polarizer 21 to increase the size of the second shielding layer 23, expand the shielding range of the second shielding layer 23, and more effectively reduce the signal interference between the first wiring 6 and the middle frame antenna 9.

[0066] In a possible implementation, as shown in FIGS. 15 and 16, FIG. 15 is another schematic view of a partial structure of a display module according to an embodiment of the present application, and FIG. 16 is a plan view of the structure of FIG. 15 in a flattened state. The bending area 3 includes a middle bending area 24 and edge bending areas 25 on both sides of the middle bending area 24. The second shielding layer 23 includes hollows 26, and the hollows 26 are located in the edge bending areas 25.

[0067] In consideration of the fact that the second shielding layer 23 includes a metal material, some hollows 26 can be arranged in the second shielding layer 23 to disperse bending stress and avoid fracture of the second shielding layer 23 due to stress concentration. Furthermore, in consideration of the fact that the middle bending area 24 corresponds to the position of the arc top of the bending part, the bending degree is greater, and the distance between the middle bending area 24 and the frame antenna 9 is closer, the hollows 26 are arranged in the edge bending areas 25 to ensure that the second shielding layer 23 has a better shielding effect in the middle bending area 24.

[0068] Further, referring again to FIG. 16, the hollows 26 can be arranged in the edge bending areas 25 in regions where the first traces 6 are not arranged. That is, in the flattened state of the display module, the first traces 6 and the hollows 26 do not overlap in the direction perpendicular to the plane on which the substrate 5 is located. In this way, the first traces 6 can still be arranged outside the shielding material, and the second shielding layer 23 can effectively improve the signal crosstalk in the edge bending areas 25.

[0069] It should be noted that in the embodiments of the present application, the shielding layer 8 in the display module can include at least one of the first sub-shielding layer 11, the second sub-shielding layer 20, and the second shielding layer 23. For example, the shielding layer 8 can include only the first sub-shielding layer 11, or can include both the first sub-shielding layer 11 and the second sub-shielding layer 20, or can include the first sub-shielding layer 11, the second sub-shielding layer 20, and the second shielding layer 23.

[0070] In a possible implementation, as shown in FIG. 17, FIG. 17 is another schematic view of a structure of a display module according to an embodiment of the present application. The display module further includes a polarizer 21 and a cover plate 18. The polarizer 21 is located at least in the display area 2 and on one side of the display panel 1. The cover plate 18 is located on the side of the polarizer 21 away from the display panel 1. The orthogonal projection of the end of the shielding layer 8 close to the binding area 4 on the cover plate 18 overlaps the orthogonal projection of the polarizer 21 on the cover plate 18, so that the shielding layer 8 has a larger size and a better shielding effect.

[0071] It should be noted that the end of the shielding layer 8 close to the binding area 4 is located on the backlight side of the display panel 1, so even if the end of the shielding layer 8 close to the binding area 4 overlaps the polarizer 21, it will not affect the normal light emission of the display panel 1.

[0072] In a possible implementation, as shown in FIG. 18, which is another schematic view of a partial structure of a display module according to an embodiment of the present application, the bending area 3 includes a middle bending area 24 and edge bending areas 25 located on both sides of the middle bending area 24.

[0073] The shielding layer 8 includes a first portion 27 and a second portion 28, the first portion 27 is located in the middle bending area 24, and the second portion 28 is located in the edge bending areas 25, wherein the thickness of the first portion 27 is greater than that of the second portion 28.

[0074] By thickening the part of the shielding layer 8 located at the position of the arch top, the shielding layer 8 has a better shielding effect at the position, and the signal interference between the metal line and the middle frame antenna 9 at the position of the arch top is improved.

[0075] In a possible implementation, as shown in FIG. 19, which is another schematic view of a partial structure of a display module according to an embodiment of the present application, the bending area 3 includes a middle bending area 24 and edge bending areas 25 located on both sides of the middle bending area 24. The shielding layer 8 includes a first portion 27 and a second portion 28, the first portion 27 is located in the middle bending area 24, and the second portion 28 is located in the edge bending areas 25.

[0076] Since the middle bending area 24 corresponds to the position of the arch top of the bending part, the bending degree is greater, therefore, the modulus of the first portion 27 can be set to be less than that of the second portion 28, and / or the elongation at break of the first portion 27 can be set to be greater than that of the second portion 28, so that the part of the shielding layer 8 at the position of the arch top has better bending performance, preventing the shielding layer 8 from cracking at the position, and improving the reliability of the shielding layer 8 at the position.

[0077] In a possible implementation, as shown in FIG. 20, which is another schematic view of a structure of a display module according to an embodiment of the present application, the display module further includes a bending protection layer 16, which is located on one side of the display panel 1 and at least in the bending area 3.

[0078] The bending protection layer 16 includes a substrate 29 and shielding particles 30 filled in the substrate 29. The substrate 29 can be a gluey substrate, so as to be directly attached to the display panel 1, and the shielding particles 30 are used for shielding or absorbing electromagnetic waves. In this structure, the bending protection layer 16 can realize the functions of reducing stress and shielding electromagnetic signals, so that the bending protection layer 16 and the shielding layer 8 are multiplexed, and thus it is not necessary to additionally set a shielding structure, which simplifies the structural design of the display module.

[0079] In a feasible embodiment, as shown in FIG. 21, which is a schematic diagram of a size of the shielding layer 8 according to an embodiment of the present application, and referring to FIG. 1 again, in order to make the shielding layer 8 have a good shielding effect, the thickness d2 of the shielding layer 8 can be set to be greater than 1 μm.

[0080] Specifically, when the shielding layer 8 is formed before the display panel 1 is bent, the thickness of the shielding layer 8 in the direction perpendicular to the plane of the substrate 5 can be made to satisfy greater than 1 μm, and thus when the display panel 1 is bent to drive the shielding layer 8 to bend, the thickness of the shielding layer 8 is still greater than 1 μm. For example, when the shielding layer 8 includes a sticky material having a shielding or absorbing electromagnetic wave function and is directly coated on the surface of the first film layer 10 or the bending protection layer 16, the coating thickness of the sticky material is greater than 1 μm.

[0081] In addition, as shown in FIG. 22, which is another schematic diagram of a structure of a display module according to an embodiment of the present application, the display module according to an embodiment of the present application can further include a support plate 31, a foam 32 and a heat dissipation copper foil 33 and the like. At the position of the frame, the side of the cover plate 18 facing the display panel 1 can be further provided with a light shielding layer 34 to avoid metal reflection. In addition, the binding area 4 can be bound with a driving chip 35 and / or a printed circuit board 36.
