[0052] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] As described in the background technology section, the wiring in the bending area of ​​the prior art is easily damaged by static electricity. The inventor found that the reason for the above phenomenon is that a bending protect liquid (BPL) is coated on the outside of the bending portion of the display panel. The BPL forms a protective layer after curing. However, since the thickness of the protective layer formed by the BPL is relatively thick, usually 90±20μm, the bending radius of the bending portion is relatively large, resulting in a relatively large width of the lower frame of the display panel. In order to reduce the width of the lower frame of the display panel by reducing the bending radius of the bending portion, the protective layer formed by the BPL is removed, resulting in the wiring in the bending portion being easily damaged by static electricity.

[0061] Based on the above technical problems, the inventors have found that the display panel has a first organic layer located in the display part on the side of the packaging layer away from the substrate, and the first organic layer has a relatively thin thickness; the protective layer is arranged at the bending part, and at least one sub-film layer of the protective layer includes the same material as the first organic body, that is, the first organic layer extends to the bending part, which not only makes the bending part have a small bending radius, but also can avoid the wiring of the bending part from being damaged by static electricity to a certain extent; further, at least one sub-film layer of the protective layer includes a second organic body and a plurality of conductive particles distributed in the second organic body. Through the arrangement of the conductive particles, the wiring of the bending part can be better prevented from being damaged by static electricity, and the required thickness of the protective layer is relatively thin.

[0064] It should be noted that, because Figures 5 to 8 The schematic diagram of the bent portion of the display panel after being bent is shown in FIG. Figure 2 and Figure 4 Similar, although Figures 5 to 8 The figure only shows the schematic diagram of the bending portion before bending, which does not affect the description of the invention spirit of the present application.

[0065] The present application provides a display panel 100, which includes a display portion 10A and a bending portion 10B located on one side of the display portion 10A, and a binding portion 10C located on a side of the bending portion 10B away from the display portion 10A, wherein the binding portion 10C is bent toward a side away from a light emitting surface of the display portion 10A. The display panel 100 includes a substrate 11, a driving circuit layer 12, an encapsulation layer 13, a first organic layer 71 and a protective layer 20. The driving circuit layer 12 is located on one side of the substrate 11 and at least on the display part 10A; the encapsulation layer 13 is located on the side of the driving circuit layer 12 away from the substrate 11 and at least on the display part 10A; the first organic layer 71 is located on the side of the encapsulation layer 13 away from the substrate 11 and at least on the display part 10A; the protective layer 20 is arranged on one side of the substrate 11 and at least on the bending part 10B; wherein, the first organic layer 71 includes a first organic body 71a; the protective layer 20 includes at least one sub-film layer, at least one sub-film layer includes a second organic body 20a and a plurality of conductive particles 20b distributed in the second organic body 20a, and at least one sub-film layer includes the same material as the first organic body 71a.

[0066] By way of example, the display panel 100 may include a substrate 11, a driving circuit layer 12 and a display function layer. The driving circuit layer 12 may include multiple pixel driving circuits, the display function layer may include multiple display pixels, the display pixels may include light-emitting devices, and the light-emitting devices may be electrically connected to the corresponding pixel driving circuits in the driving circuit layer 12. The structure and display type of the driving circuit layer 12 and the display function layer are not limited herein.

[0067] For example, the display function layer may be disposed between the driving circuit layer 12 and the encapsulation layer 13 .

[0068] For example, the display part 10A, the bending part 10B and the binding part 10C are connected in sequence, the display part 10A is provided with a display function layer, the bending part 10B can be bent to achieve a narrow frame, and the binding part 10C can be electrically connected to a driving chip or a circuit board 40, etc.

[0069] For example, the display panel 100 may further include an optically clear adhesive (OCA) 16 disposed on the side of the encapsulation layer 13 / first organic layer 71 away from the substrate 11, and a protective cover plate 17 (CG, Cover Glass) attached to the side of the optical adhesive layer 16 away from the substrate 11 through the optical adhesive layer 16. The material of the protective cover plate 17 may be glass or ultra-thin glass, etc., and the material of the protective cover plate 17 is not limited herein.

[0070] For example, Figures 1 to 4As shown in FIG. 1 , the side of the protective cover plate 17 away from the substrate 11 is the light emitting surface of the display portion 10A or the display panel 100 , that is, the light emitted by the display panel 100 is emitted from the encapsulation layer 13 and the protective cover plate 17 to the human eye.

[0071] For example, the display panel 100 has a first organic layer 71 located in the display part 10A on the side of the encapsulation layer 13 away from the substrate 11, and the first organic layer 71 has a relatively thin thickness; the protective layer 20 is arranged in the bending part 10B, and at least one sub-film layer of the protective layer 20 includes the same material as the first organic body 71a, that is, the first organic layer 71 extends from the display part 10A to the bending part 10B, which not only makes the bending part 10B have a small bending radius, but also can protect the wiring of the bending part 10B from being damaged by static electricity.

[0072] It should be noted that in the prior art, a bending protection liquid (BPL) is coated on the outer side of the bending portion 10B of the display panel 100. The BPL forms a protective layer after curing. The formation of the BPL is completed in the module process (a process after the motherboard of the display panel 100 is cut into multiple small pieces). The manufacturing process of the BPL is relatively rough, so that the thickness of the protective layer formed by the BPL is relatively thick, usually 90±20μm. The formation of the first organic layer 71 is completed before the module process (a process before the motherboard of the display panel 100 is cut into multiple small pieces), for example, as part of the manufacturing process of the touch layer 14, for example, as part of the manufacturing process of the filter function layer 15. The manufacturing process of the first organic layer 71 is relatively more refined, for example, the thickness of the first organic layer 71 is between 0.5 microns and 5 microns, and the thickness of the first organic layer 71 is thinner.

[0073] For example, further, at least one sub-film layer of the protective layer 20 includes a second organic body 20a and a plurality of conductive particles 20b distributed in the second organic body 20a. By setting the conductive particles 20b, the wiring of the bending portion 10B can be better prevented from being damaged by static electricity, and the required thickness of the protective layer 20 is relatively thin.

[0074] In the embodiment of the present application, the display panel 100 has a first organic layer 71 located in the display part 10A on the side of the encapsulation layer 13 away from the substrate 11, and the first organic layer 71 has a relatively thin thickness; the protective layer 20 is arranged in the bending part 10B, and at least one sub-film layer of the protective layer 20 includes the same material as the first organic body 71a, that is, the first organic layer 71 extends from the display part 10A to the bending part 10B, which not only makes the bending part 10B have a small bending radius, but also can protect the wiring of the bending part 10B from being damaged by static electricity. Furthermore, at least one sub-film layer of the protective layer 20 includes a second organic body 20a and a plurality of conductive particles 20b distributed in the second organic body 20a. By setting the conductive particles 20b, the wiring of the bending part 10B can be better prevented from being damaged by static electricity, and the required thickness of the protective layer 20 is relatively thin.

[0075] In some embodiments, Figure 1 and Figure 2 As shown, the display panel 100 also includes a touch layer 14, which includes a touch function layer 141 and a touch flat layer 142. The touch function layer 141 is located on a side of the encapsulation layer 13 away from the substrate 11, and the touch flat layer 142 is located on a side of the touch function layer 141 away from the substrate 11, wherein the first organic layer 71 is the touch flat layer 142.

[0076] For example, the touch function layer 141 may include a plurality of touch electrodes to implement the touch function of the display panel 100 . For example, the touch function layer 141 may include a plurality of touch sensing electrodes and a plurality of touch driving electrodes. The structure of the touch function layer 141 is not limited herein.

[0077] For example, the touch planarizing layer 142 is located on a side of the touch function layer 141 away from the substrate 11 . The touch planarizing layer 142 can planarize the surface of the touch function layer 141 away from the substrate 11 to facilitate subsequent manufacturing processes.

[0078] For example, the first organic layer 71 is a touch-sensitive flat layer 142 , and the touch-sensitive flat layer 142 may extend from the display portion 10A to the bending portion 10B to protect the bending portion 10B.

[0079] In some embodiments, Figure 3 and Figure 4 As shown, the display panel 100 also includes a filter functional layer 15, which includes a color resist layer 151 and a filter flat layer 152. The color resist layer 151 is located on the side of the encapsulation layer 13 away from the substrate 11, and the filter flat layer 152 is located on the side of the color resist layer 151 away from the substrate 11, wherein the first organic layer 71 is the filter flat layer 152.

[0080] For example, the color resist layer 151 may include a plurality of color resist blocks and a black matrix (BM), the black matrix includes a plurality of black matrix openings, and the color resist blocks are at least arranged in the corresponding black matrix openings. The color resist blocks can filter the light emitted by the corresponding light emitting device. By setting the filter function layer 15, the polarizer in the display panel 100 can be removed, thereby reducing the thickness of the display panel 100 and reducing the cost.

[0081] For example, the filter flattening layer 152 is located on a side of the color resist layer 151 away from the substrate 11 . The filter flattening layer 152 can flatten the surface of the color resist layer 151 away from the substrate 11 , so as to facilitate subsequent manufacturing processes.

[0082] For example, the first organic layer 71 is a filter flat layer 152 , and the filter flat layer 152 may extend from the display portion 10A to the bent portion 10B to protect the bent portion 10B.

[0083] In some embodiments, Figure 1 and Figure 2 As shown, or as Figure 3 and Figure 4 As shown, the protective layer 20 includes a first protective layer 21, the first protective layer 21 includes a second organic body 20a and a plurality of conductive particles 20b, the second organic body 20a and the first organic body 71a are made of the same material; the material of the first organic layer 71 only includes the first organic body 71a.

[0084] For example, Figure 1 and Figure 2 The first organic layer 71 is a touch flat layer 142 , and the material of the first organic layer 71 only includes a first organic body 71 a (excluding conductive particles). The first protective layer 21 includes a second organic body 20 a and a plurality of conductive particles 20 b . The second organic body 20 a is made of the same material as the first organic body 71 a .

[0085] For example, Figure 1 and Figure 2 When manufacturing the touch flat layer 142, the touch flat layer 142 extends to the bending portion 10B to form the first protective layer 21. The touch flat layer 142 only includes the first organic body 71a (excluding conductive particles) in the display portion 10A. The touch flat layer 142 simultaneously forms the second organic body 20a and multiple conductive particles 20b in the second organic body 20a in the bending portion 10B, which can better play the role of electrostatic protection in the bending portion 10B.

[0086] For example, Figure 3 and Figure 4As shown, the first organic layer 71 is a filter flattening layer 152, and the material of the first organic layer 71 only includes a first organic body 71a (excluding conductive particles). The first protective layer 21 includes a second organic body 20a and a plurality of conductive particles 20b. The second organic body 20a is made of the same material as the first organic body 71a.

[0087] For example, Figure 3 and Figure 4 When manufacturing the filter flat layer 152, the filter flat layer 152 extends to the bending portion 10B to form the first protective layer 21. The filter flat layer 152 only includes the first organic body 71a (excluding conductive particles) in the display portion 10A. The filter flat layer 152 simultaneously forms the second organic body 20a and multiple conductive particles 20b in the second organic body 20a in the bending portion 10B, which can better play the role of electrostatic protection in the bending portion 10B.

[0088] In some embodiments, Figure 5 As shown, or as Figure 6 As shown, the protective layer 20 includes a first protective layer 21, the first protective layer 21 includes a second organic body 20a and a plurality of conductive particles 20b, the second organic body 20a is made of the same material as the first organic body 71a, and the first organic layer 71 also includes a plurality of conductive particles 20b distributed in the first organic body 71a.

[0089] For example, Figure 5 As shown, when manufacturing the touch flat layer 142, the touch flat layer 142 is the first organic layer 71, and the touch flat layer 142 extends to the bending portion 10B to form a first protective layer 21. The touch flat layer 142 includes a first organic body 71a and a plurality of conductive particles 20b distributed in the first organic body 71a in the display portion 10A. The touch flat layer 142 simultaneously forms a second organic body 20a and a plurality of conductive particles 20b in the second organic body 20a in the bending portion 10B. The second organic body 20a is made of the same material as the first organic body 71a, and can better play a role in electrostatic protection in the bending portion 10B.

[0090] For example, Figure 6 As shown, when manufacturing the filter flat layer 152, the filter flat layer 152 is the first organic layer 71, and the filter flat layer 152 extends to the bending portion 10B to form a first protective layer 21. The filter flat layer 152 includes a first organic body 71a and a plurality of conductive particles 20b distributed in the first organic body 71a in the display portion 10A. The filter flat layer 152 simultaneously forms a second organic body 20a and a plurality of conductive particles 20b in the second organic body 20a in the bending portion 10B. The second organic body 20a is made of the same material as the first organic body 71a, and can better play a role in electrostatic protection in the bending portion 10B.

[0091] In some embodiments, Figure 5 As shown, or as Figure 6 As shown, the display panel 100 further includes a partition groove 145J, and the partition groove 145J is disposed between the first organic layer 71 and the first protection layer 21 .

[0092] For example, Figure 5 As shown, the touch flat layer 142 includes a first organic body 71a and a plurality of conductive particles 20b distributed in the first organic body 71a in the display portion 10A, and the touch flat layer 142 simultaneously forms a second organic body 20a and a plurality of conductive particles 20b in the second organic body 20a in the bending portion 10B. In order to prevent static electricity from being transferred from the bending portion 10B to the display portion 10A, a partition groove 145J is provided between the portion of the touch flat layer 142 located in the display portion 10A and the portion located in the bending portion 10B to block the transfer of static electricity.

[0093] For example, Figure 6 As shown, the filter flat layer 152 includes a first organic body 71a and a plurality of conductive particles 20b distributed in the first organic body 71a in the display portion 10A, and the filter flat layer 152 simultaneously forms a second organic body 20a and a plurality of conductive particles 20b in the second organic body 20a in the bending portion 10B. In order to prevent the static electricity in the bending portion 10B from being transferred to the display portion 10A, a partition groove 145J is further provided between the portion of the filter flat layer 152 located in the display portion 10A and the portion located in the bending portion 10B to block the static electricity transfer.

[0095] For example, Figure 7 As shown, in some embodiments, the touch flat layer 142 does not include conductive particles, and the touch flat layer 142 extends to the bending portion to form a first protective layer 21. At this time, a second protective layer 22 is arranged on the side of the first protective layer 21 away from the substrate 11. The second protective layer 22 includes a second organic body 20a and a plurality of conductive particles 20b distributed in the second organic body 20a, which can well protect the bending portion 10B.

The second protective layer 22 includes a second organic body 20a and a plurality of conductive particles 20b distributed in the second organic body 20a, which can well protect the bending portion 10B.

[0097] For example, Figure 7 As shown, the touch flat layer 142 or the filter flat layer 152 extends to the bending portion 10B, and a second protective layer 22 can be separately provided on the side of the first protective layer 21 away from the substrate 11, for example, formed in a module process. At this time, since the first protective layer 21 exists on the bending portion 10B, the first protective layer 21 can play a protective role when the bending portion 10B is bent, and the second protective layer 22 can be formed after the bending portion 10B is bent, which does not affect the frame of the display panel 100.

[0098] In some embodiments, Figure 8 As shown, the display panel 100 further includes a touch layer 14 and a filter function layer 15.
