The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0041] When describing positional relationships, unless otherwise specified, when an element such as a layer, film, or substrate is referred to as being "on" another element, it can be directly on the other element or there may be intervening elements. Further, when a layer is referred to as being "under" another layer, it can be directly under or there may be one or more intervening elements. It is also understood that when a layer is referred to as being "between" two layers, it can be the only layer between the two layers or there may be one or more intervening elements.

[0042] In the case of using “including”, “having”, and “comprising” described herein, another component may be added unless a clear limiting term such as “only”, “consisting of”, etc. is used. Unless mentioned otherwise, a term in the singular form may include a plural form and should not be understood as being one in number.

[0043] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of the present application.

[0044] It should also be understood that when interpreting an element, even if not explicitly described, the element is interpreted as including a range of error, which should be within the acceptable deviation range of the specific value determined by those skilled in the art. For example, "approximately", "approximately" or "substantially" can mean within one or more standard deviations, which are not limited here.

[0045] Furthermore, in the specification, the phrase “planar distribution schematic diagram” refers to a drawing when a target portion is viewed from above, and the phrase “cross-sectional schematic diagram” refers to a drawing when a section taken by vertically cutting the target portion is viewed from the side.

[0046] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0047] It is obvious to those skilled in the art that various modifications and changes can be made in this application without departing from the spirit or scope of this application. Therefore, this application is intended to cover modifications and changes of this application that fall within the scope of the corresponding claims (technical solutions claimed for protection) and their equivalents. It should be noted that the implementation methods provided in the embodiments of this application can be combined with each other without contradiction.

[0048] As described in the background technology section, there is a problem in the prior art that it is difficult to simultaneously take into account the reduction of the bending radius of the bending portion and the improvement of the anti-static ability. The display module includes a display panel, a first backplane and a second backplane, the display panel includes a display area and a bending area located on one side of the display area, and a binding area located on the side of the bending area away from the display area, the binding area is bent toward the side away from the light-emitting surface of the display module; the first backplane is located on the side of the display area away from the light-emitting surface; the second backplane is located on the side of the binding area facing the light-emitting surface, and is arranged opposite to the first backplane. The inventor found that in the prior art, in order to protect the outer surface of the bending area away from the first backplane and the second backplane and avoid electrostatic damage from sources such as air, it is necessary to set a protective adhesive on the outer surface of the bending area away from the first backplane and the second backplane. However, the setting of the protective adhesive will cause the bending radius of the bending area to increase and / or the thickness of the bending area to increase, resulting in an increase in the width of the lower frame of the display module; removing the protective adhesive will cause the bending area to be easily damaged by static electricity from sources such as air, thereby causing damage to the display module and display abnormality.

[0049] Based on the above technical problems, the inventors have found that by setting a first filling part in the first space part, the first space part is located between the first back plate, the second back plate and the support structure and the bending area; the support structure is located between the first back plate and the second back plate, and the support structure includes at least one conductive layer; the bending area includes at least one opening that runs through the bending area, and the first filling part includes a conductive material; on the side surface of the bending area away from the support structure, the opening exposes the first filling part; the effect of reducing the bending radius of the bending part and improving the antistatic ability can be achieved at the same time. On the first hand, the opening in the bending area exposes the first filling part, the first filling part includes a conductive material, and the first filling part is connected to the conductive layer in the support structure. When the bending area is subjected to static electricity from sources such as air, the static electricity can be released through the path of the opening, the first filling part and the conductive layer, thereby improving the antistatic ability of the bending area; on the second hand, the protective adhesive material of the bending area away from the support structure can be removed (no protective adhesive material is provided), thereby reducing the bending radius of the bending area and / or reducing the thickness of the bending area, and reducing the width of the lower frame of the display module. In addition, in the third aspect, the first filling portion is arranged in the first space portion. When the bending zone is impacted by external force, the first filling portion can buffer or resist the external impact force, thereby avoiding excessive deformation of the bending zone and causing breakage of the wiring in the bending zone, so that the first filling portion can enhance the mechanical strength of the bending zone to resist external impact force.

[0050] The above is the core idea of ​​this application. The technical solutions in the embodiments of this application will be described clearly and completely below in conjunction with the drawings in the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0055] The present application provides a display module 200, which includes a display panel 10, a first back plate 21a, a second back plate 21b, a support structure 30, and a first filling portion 50. The display panel 10 includes a display area AA and a bending area 10B located on one side of the display area AA, and a binding area 10C located on the side of the bending area 10B away from the display area AA, and the binding area 10C is bent toward the side away from the light-emitting surface of the display module 200; the first back plate 21a is located on the side of the display area AA away from the light-emitting surface; the second back plate 21b is located on the side of the binding area 10C facing the light-emitting surface, and is arranged opposite to the first back plate 21a; the support structure 30 is located between the first back plate 21a and the second back plate 21b, the support structure 30 includes at least one conductive layer 33; the first filling portion 50 is filled in the first space portion 10t, and the first space portion 10t is located between the first backplane 21a, the second backplane 21b and the support structure 30 and the bending zone 10B; wherein the bending zone 10B includes at least one opening 10k passing through the bending zone 10B, and the first filling portion 50 includes a conductive material; on the side surface of the bending zone 10B away from the support structure 30, the opening 10k exposes the first filling portion 50.

[0056] For example, Figure 2As shown, the display panel 10 may include a substrate 11 and a display function layer 12 . The display function layer 12 may include a plurality of display pixels. The display pixels may include light-emitting devices. The structure and display type of the display function layer 12 are not limited herein.

[0057] For example, combined with Figure 1 and Figure 2 As shown, from the perspective of whether each part of the display panel 10 displays an image, the display panel 10 may include a display area AA and a non-display area BB surrounding the display area AA, and the bending area 10B and the binding area 10C are located in the non-display area BB, but the structure of the display panel 10 is not limited to this. For example, the non-display area BB may partially surround the display area AA.

[0058] For example, combined with Figure 1 and Figure 2 As shown, from the morphology of each part of the display panel 10, the display panel 10 includes a flat display area 10A, a bending area 10B and a binding area 10C connected in sequence, the bending area 10B can be bent to achieve a narrow frame, the bending area 10B is provided with a plurality of signal lines 102, and the binding area 10C is provided with a binding terminal 101, which can be electrically connected to the driving chip 40 or a circuit board. The flat display area 10A is located in the display area AA.

[0059] For example, Figures 2 to 5 As shown, the display module 200 may also include a polarizer attached to the side of the display function layer 12 away from the substrate 11 (the polarizer is attached to the light-emitting surface of the display panel 10), and a protective cover plate 14 (CG, Cover Glass) attached to the side of the polarizer (Polarizer, POL) away from the substrate 11 through an optically clear adhesive layer 13 (Optically Clear Adhesive, OCA). The material of the protective cover plate 14 can be glass or ultra-thin glass, etc., and the material of the protective cover plate 14 is not limited here. For example, the structure of the display module 200 is not limited to Figure 2 As shown, for example, the display module 200 may not include a polarizer.

[0060] For example, Figures 2 to 5 As shown, the side of the protective cover plate 14 away from the substrate 11 is the display area AA (or the flat display area 10A) or the light emitting surface of the display panel 10 , that is, the light emitted by the display panel 10 is emitted from the protective cover plate 14 to the human eye.

[0061] For example, combined with Figure 1 As shown, the first backplane 21a is attached to the side of the substrate 11 away from the display function layer 12. The second backplane 21b is attached to the same side of the substrate 11 as the first backplane 21a.

[0062] For example, Figures 2 to 5 As shown, after the bending area 10B is bent, the display area AA and the binding area 10C are arranged back to back or opposite to each other, and the first back plate 21a is located on the side of the display area AA away from the light emitting surface; the second back plate 21b is located on the side of the binding area 10C facing the light emitting surface and is arranged opposite to the first back plate 21a.

[0063] For example, Figures 2 to 5 As shown, the support structure 30 is located between the first back plate 21a and the second back plate 21b, and the support structure 30 includes at least one conductive layer 33; the support structure 30 can use a super clean foam composite film (Super Clean Foam, referred to as SCF), SCF is a material composed of super clean foam and composite film, but not limited to this, for example, the support structure 30 can include a rigid support sublayer and a conductive layer (heat dissipation layer).

[0064] For example, Figures 2 to 5 As shown, when the support structure 30 includes an ultra-clean foam composite film, the ultra-clean foam is used as a substrate, and one or more layers of functional films are composited to achieve specific functional requirements. SCF has the advantages of high strength, corrosion resistance, wear resistance and high temperature resistance. Among them, the SCF composite film has high mechanical strength and tensile resistance, which can effectively protect the surface of the substrate from external impact and wear. The SCF composite film has good chemical corrosion resistance and can resist corrosion in acid, alkali, salt water and other environments to protect the substrate from damage. In addition, the SCF composite film has a smooth surface and excellent wear resistance, which can extend the service life of the substrate. The SCF composite film also has a certain high temperature resistance and can operate stably under high temperature conditions. SCF material also has an advantage that it is light in weight and will not increase the load on the flexible display panel, which is suitable for application scenarios that require lightweight.

[0065] For example, Figures 2 to 4 Taking the example that the support structure 30 includes an ultra-clean foam composite film, the support structure 30 includes an adhesive layer 31, a buffer layer 32 and a conductive layer 33 (heat dissipation layer). The material of the buffer layer 32 can be foam, and the material of the conductive layer 33 can be copper foil, but is not limited thereto.

[0066] For example, Figures 2 to 5 As shown, the first filling part 50 fills the first space 10t, and the first space 10t is located between the first back plate 21a, the second back plate 21b, the support structure 30 and the bending area 10B. The first space 10t can be fully or partially filled by the first filling part 50.

[0067] For example, Figures 2 to 5 As shown, on a side surface of the bending region 10B away from the supporting structure 30 , the opening 10 k exposes the first filling portion 50 , and the first filling portion 50 is in contact with the conductive layer 33 .

[0068] For example, Figures 2 to 5 As shown, the bending zone 10B includes at least one opening 10k that passes through the bending zone 10B, and the opening 10k passes through the substrate 11; when other insulating layers or other film layers are provided on the substrate 11 of the bending zone 10B, the opening 10k also passes through other insulating layers or other film layers provided on the substrate 11, so that on the side surface of the bending zone 10B away from the supporting structure 30, the opening 10k exposes the first filling portion 50.

[0069] For example, Figure 6 As shown, the release process of static electricity SD1 is illustrated. When the bending area 10B is subjected to static electricity SD1 from the air, the static electricity SD1 can be released through the path of the opening 10k, the first filling portion 50 and the conductive layer 33 ( Figure 6 (see arrow line in the first space portion 10t).

[0070] In the embodiment of the present application, a first filling portion 50 is provided in the first space portion 10t, and the first space portion 10t is located between the first back plate 21a, the second back plate 21b and the support structure 30 and the bending zone 10B; the support structure 30 is located between the first back plate 21a and the second back plate 21b, and the support structure 30 includes at least one conductive layer 33; the bending zone 10B includes at least one opening 10k passing through the bending zone 10B, and the first filling portion 50 includes a conductive material; on the side surface of the bending zone 10B away from the support structure 30, the opening 10k exposes the first filling portion 50; the effect of reducing the bending radius of the bending portion and improving the anti-static ability can be achieved. On the one hand, the opening 10k of the bending zone 10B exposes the first filling portion 50, and the first filling portion 50 includes a conductive material. The first filling portion 50 is connected to the conductive layer 33 in the supporting structure 30. When the bending zone 10B is subjected to static electricity from sources such as the air, the static electricity can be released through the path of the opening 10k, the first filling portion 50 and the conductive layer 33, thereby improving the anti-static ability of the bending zone 10B; on the other hand, the protective glue material of the bending zone 10B away from the supporting structure 30 can be removed (not set), and the surface of the bending zone 10B away from the supporting structure 30 is exposed, thereby reducing the bending radius of the bending zone 10B and / or reducing the thickness of the bending zone 10B, thereby reducing the width of the lower frame of the display module 200. In addition, in the third aspect, the first filling portion 50 is arranged in the first space portion 10t. When the bending zone 10B is impacted by external force, the first filling portion 50 can buffer or resist the external impact force, thereby avoiding excessive deformation of the bending zone 10B and causing breakage of the wiring in the bending zone 10B, so that the first filling portion 50 can enhance the mechanical strength of the bending zone 10B to resist external impact force.

[0071] In some embodiments, Figures 2 to 5As shown, the first filling portion 50 includes a filling body 51 and a plurality of conductive particles 52 dispersed in the filling body 51 .

[0072] For example, Figures 2 to 5 As shown, the first filling part 50 includes a filling body 51 and a plurality of conductive particles 52, which can realize the conductive function of the first filling part 50 and facilitate the first filling part 50 to be filled in the first space part 10t. For example, the material of the first filling part 50 in a fluid or liquid state can be filled in the first space part 10t, and then the first filling part 50 is formed through a drying process, which has the effect of simple manufacturing process.

[0073] For example, in some other embodiments, the first filling part 50 may be a conductive metal.

[0074] In some embodiments, Figures 2 to 5 As shown, the bending zone 10B includes a first sub-bending zone 10B1 close to the display area AA and a third sub-bending zone 10B3 close to the binding area 10C, and a second sub-bending zone 10B2 connecting the first sub-bending zone 10B1 and the third sub-bending zone 10B3, and the bending curvature of the second sub-bending zone 10B2 is greater than the bending curvature of the first sub-bending zone 10B1 and the bending curvature of the third sub-bending zone 10B3; the density of the openings 10k in at least one of the first sub-bending zone 10B1 and the third sub-bending zone 10B3 is greater than the density of the openings 10k in the second sub-bending zone 10B2.

[0075] For example, Figures 2 to 5 As shown, the display area AA, the first sub-bending area 10B1, the second sub-bending area 10B2, the third sub-bending area 10B3 and the binding area 10C are connected in sequence.

[0076] For example, Figures 2 to 5 As shown, the bending curvature of the second sub-bending zone 10B2 is greater than the bending curvature of the first sub-bending zone 10B1 and the bending curvature of the third sub-bending zone 10B3, that is, the bending degree of the second sub-bending zone 10B2 is greater than that of the first sub-bending zone 10B1 and the third sub-bending zone 10B3, the stress of the second sub-bending zone 10B2 is more concentrated, and the density of the openings 10k in at least one of the first sub-bending zone 10B1 and the third sub-bending zone 10B3 is greater than the density of the openings 10k in the second sub-bending zone 10B2, that is, a smaller density of openings 10k is set in the second sub-bending zone 10B2, which can avoid damage such as breakage or cracks in the second sub-bending zone 10B2.

[0077] For example, the density of the openings 10k in at least one of the first sub-bending zone 10B1 and the third sub-bending zone 10B3 is greater than the density of the openings 10k in the second sub-bending zone 10B2. The number of openings 10k per unit area in the second sub-bending zone 10B2 may be less, the area of ​​the openings 10k per unit area in the second sub-bending zone 10B2 may be smaller, the total number of openings 10k in the second sub-bending zone 10B2 may be less, or the total area of ​​the openings 10k in the second sub-bending zone 10B2 may be smaller.

[0078] For example, Figure 2 As shown in FIG. 1 , it is shown that the second sub-bending region 10B2 is not provided with an opening 10k. Figure 3 As shown, it is indicated that the second sub-bending region 10B2 is provided with an opening 10k.

[0079] In some embodiments, Figures 2 to 5 As shown, the length of the opening 10 k is less than or equal to the length of the conductive particle 52 .

[0080] For example, the length of the opening 10k refers to the maximum length of the opening, and the length of the conductive particle 52 refers to the maximum length of the conductive particle 52. The length of the opening 10k is less than or equal to the length of the conductive particle 52, which can prevent the conductive particle 52 from falling through the opening 10k and avoid damage to the first filling part 50.

[0081] For example, in some other embodiments, the length of the opening 10k is greater than the length of the conductive particle 52. In this case, the material of the first filling portion 50 in a fluid or liquid state can be injected into the first space portion 10t through the opening 10k, and then the first filling portion 50 is formed through a drying process, which has the effect of simplifying the manufacturing process.

[0082] In some embodiments, Figure 1 As shown, the display panel 10 includes a plurality of signal lines 102 located in the bending area 10B, and the openings 10k are arranged to avoid the signal lines.

[0083] For example, Figure 1 As shown, the display panel 10 includes multiple signal lines 102 and / or circuits located in the bending area 10B, and the opening 10k is arranged to avoid the multiple signal lines and circuits located in the bending area 10B, on the one hand to avoid damage to the multiple signal lines and circuits, on the other hand to avoid external static electricity from entering the multiple signal lines 102 and circuits.

[0084] For example, Figure 1 As shown, the opening 10k avoids the multiple signal lines 102 and circuits located in the bending area 10B, that is, the opening 10k is spaced apart from the multiple signal lines 102 and circuits located in the bending area 10B.

[0085] In some embodiments, Figure 2 and Figure 3 As shown, the first filling portion 50 is connected to the end surface of the conductive layer 33 close to the bending region 10B.

[0086] For example, Figure 2 and Figure 3 As shown, the first filling portion 50 is connected to the end surface of the conductive layer 33 close to the bending region 10B, that is, static electricity is released through the end surface of the conductive layer 33 close to the bending region 10B.

[0087] In some embodiments, Figure 4 As shown, the support structure 30 also includes a first sub-support structure 301 located on the side of the conductive layer 33 close to the first backplane 21a. In a direction parallel to the plane where the first backplane 21a is located, the conductive layer 33 includes a first protrusion 33t1 protruding toward the bending area 10B relative to the first sub-support structure 301; the first filling portion 50 is connected to at least the surface of the first protrusion 33t1 close to the first backplane 21a.

[0088] For example, Figure 4 As shown, when the support structure 30 includes an ultra-clean foam composite film, the first sub-support structure 301 may be a buffer layer 32. However, the support structure 30 is not limited to the ultra-clean foam composite film.

[0089] For example, Figure 4 As shown, the conductive layer 33 includes a first protrusion 33t1 protruding toward the bending area 10B relative to the first sub-support structure 301, and the surface of the first protrusion 33t1 close to the first back plate 21a is a first sub-surface 331. The first filling portion 50 is at least connected to the first sub-surface 331 to release static electricity. Figure 4 It is also shown that the first filling portion 50 is also connected to the end surface of the conductive layer 33 close to the bending region 10B.

[0090] In some embodiments, Figure 5 As shown, the support structure 30 also includes a second sub-support structure 302 located on the side of the conductive layer 33 close to the second backplane 21b. In a direction parallel to the plane where the first backplane 21a is located, the conductive layer 33 includes a second protrusion 33t2 protruding toward the bending area 10B relative to the second sub-support structure 302; the first filling portion 50 is connected to at least the surface of the second protrusion 33t2 close to the second backplane 21b.

[0091] For example, Figure 5 As shown, the support structure 30 may include an adhesive layer 31 , a conductive layer 33 , and a buffer layer 32 stacked in sequence, and the adhesive layer 31 is located on a side of the conductive layer 33 close to the first back plate 21 a .

[0092] For example, in some other embodiments, the support structure 30 includes an ultra-clean foam composite film, and the support structure 30 includes an adhesive layer 31, a buffer layer 32 and a conductive layer 33 stacked in sequence, the adhesive layer 32 is located on the side of the buffer layer 32 close to the first backplane 21a, and a second sub-support structure 302 is arranged on the side of the conductive layer 33 close to the second backplane 21b.

[0093] For example, the conductive layer 33 includes a second protrusion 33t2 protruding toward the bending area 10B relative to the second sub-support structure 302, the surface of the second protrusion 33t2 close to the second back plate 21b is the second sub-surface 332, and the first filling portion 50 is at least connected to the second sub-surface 332 to release static electricity. Figure 5 It is also shown that the first filling portion 50 is also connected to the end surface of the conductive layer 33 close to the bending region 10B.

[0094] In some embodiments, the material of the first filling part 50 includes an elastic organic material; and / or the material of the first filling part 50 extends into the at least one opening 10 k .

[0095] For example, the material of the first filling portion 50 includes elastic organic material, so that the first filling portion 50 can buffer external impact force, avoid breakage of the routing of the bending zone 10B, and enhance the mechanical strength of the bending zone 10B to resist external impact force.

[0096] For example, the material of the first filling portion 50 extends into the opening 10 k , and when the bending area 10B is subjected to static electricity from a source such as the air, the static electricity can be released more quickly through the first filling portion 50 .
