[0052] For the purpose of promoting an understanding of the principles of the application, reference will now be made to the embodiments illustrated in the drawings. There can, of course, be many embodiments of the application and the specific embodiments described herein are not intended to limit the application to the described embodiments. Rather, the described embodiments are intended to be illustrative of the application.
[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. 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 this description, the terms "may" and "can" include any one of, or all of, the possible equivalents. The use of the term "including" in describing the elements of the application is not a limitation and means that one or more of the specified elements can be included.
[0054] In describing a position relationship, unless otherwise defined, 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 intervening elements can also be present. In addition, when a layer is referred to as being "under" or "beneath" another layer, it can be directly under the other layer, or one or more intervening layers can also be present. It will also be understood that when a layer is referred to as being "between" two layers, it can be the only layer between the two layers, or one or more intervening layers can also be present.
[0055] In the case of using "include", "have", and "contain" described herein, unless the explicit limiting term such as "only", "consisting of", etc. is used, another component can also be added. Unless otherwise mentioned, the singular form of the term can include the plural form, and cannot be understood as the number of one.
[0056] It should be understood that, although the terms "first", "second" and the like can 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. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present application.
[0057] It should also be understood that in interpreting the elements, although not expressly stated, the elements are to be construed as including an acceptable range of error around the stated value, as would be determined by one of ordinary skill in the art. For example, "about," "approximately," or "substantially" can mean within one or more standard deviations, as not limited herein.
[0058] Further, in the specification, the phrase "plan view schematic diagram" refers to a drawing when the target portion is viewed from above, and the phrase "cross-sectional view schematic diagram" refers to a drawing when a section is taken by cutting the target portion vertically and viewed from the side.
[0059] Further, the drawings are not drawn to scale 1:1, and the relative sizes of the elements are drawn in the drawings only by way of example, and not necessarily in true scale.
[0060] As described in the background section, the prior art has the problem that the wiring of the bending area is easily damaged by static electricity. The inventors have found that the reason for the above phenomenon is that a bending portion protection liquid (BPL) is coated outside the bending portion of the display panel, and the BPL forms a protection layer after curing. However, since the thickness of the protection layer formed by the BPL is relatively thick, usually 90±20 μm, 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 protection layer formed by the BPL is removed, resulting in the problem that the wiring of the bending portion is easily damaged by static electricity.
[0061] Based on the above technical problem, the inventors have found that the display panel has a first organic layer located in the display portion on the side of the encapsulation layer away from the substrate, and the first organic layer has a relatively thin thickness; the protection layer is arranged in the bending portion, and at least one sub-film layer of the protection layer comprises the same material as the first organic body, i.e., the first organic layer extends to the bending portion, not only making the bending portion have a small bending radius, but also to a certain extent avoiding the wiring of the bending portion being damaged by static electricity; further, at least one sub-film layer of the protection layer comprises a second organic body and a plurality of conductive particles distributed in the second organic body, by arranging the conductive particles, the wiring of the bending portion can be better avoided from being damaged by static electricity, and the required thickness of the protection layer is relatively thin.

[0064] It should be noted that, because Figures 5 to 8 The diagram below shows the bent portion of the display panel after bending. Figure 2 and Figure 4 Similar, although Figures 5 to 8 The diagram only shows the bending part before bending, and does not affect the description of the spirit of the invention in this application.
[0065] The application provides a display panel 100, which comprises a display part 10A, a bending part 10B located on one side of the display part 10A, and a binding part 10C located on the side of the bending part 10B away from the display part 10A, the binding part 10C is bent towards the side away from the light-out surface of the display part 10A, and the display panel 100 comprises 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; and the protective layer 20 is arranged on one side of the substrate 11 and located on the bending part 10B. The first organic layer 71 comprises a first organic body 71a; the protective layer 20 comprises at least one sub-film layer, the at least one sub-film layer comprises a second organic body 20a and a plurality of conductive particles 20b distributed in the second organic body 20a, and the at least one sub-film layer comprises the same material as the first organic body 71a.
[0066] For example, the display panel 100 can comprise the substrate 11, the driving circuit layer 12 and a display functional layer, the driving circuit layer 12 can comprise a plurality of pixel driving circuits, the display functional layer can comprise a plurality of display pixels, the display pixel can comprise a light-emitting device, the light-emitting device can be electrically connected with the corresponding pixel driving circuit in the driving circuit layer 12, and the structure and display type of the driving circuit layer 12 and the display functional layer are not limited herein.
[0067] For example, the display functional layer can be arranged 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 sequentially connected, the display part 10A is provided with the display functional layer, the bending part 10B can be bent to realize narrow frame, and the binding part 10C can be electrically connected with a driving chip or a circuit board 40.
[0069] For example, the display panel 100 can further comprise an optical adhesive layer 16 (Optically Clear Adhesive, OCA) arranged on the side of the encapsulation layer 13 / the first organic layer 71 away from the substrate 11, and a protective cover plate 17 (CG, Cover Glass) attached on the side of the optical adhesive layer 16 away from the substrate 11 through the optical adhesive layer 16, and the material of the protective cover plate 17 can be glass or ultra-thin glass, and the material of the protective cover plate 17 is not limited herein.
[0070] For example, as shown in FIG. 1, Figures 1 to 4As shown in the figure, the side of the protective cover plate 17 away from the base 11 is the light emitting surface of the display panel 100, i.e. 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 on the side of the encapsulation layer 13 away from the base 11, the first organic layer 71 has a relatively thin thickness; the protective layer 20 is arranged on the bending portion 10B, at least one sub-film layer of the protective layer 20 comprises the same material as the first organic body 71a, i.e. the first organic layer 71 is extended from the display portion 10A to the bending portion 10B, not only making the bending portion 10B have a small bending radius, but also protecting the wires of the bending portion 10B from being damaged by static electricity.
[0072] It should be noted that the prior art has a bending portion protection liquid (Bending Protect Liquid, BPL) coated on the outside of the bending portion 10B of the display panel 100, the BPL forms a protective layer after curing, and the formation of the BPL is completed in the module process (after the mother version 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 first organic layer 71 is formed before the module process (before the mother version 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 light filtering functional layer 15, the manufacturing process of the first organic layer 71 is relatively more precise, 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 comprises a second organic body 20a and a plurality of conductive particles 20b distributed in the second organic body 20a, through the arrangement of the conductive particles 20b, the wires of the bending portion 10B can be better protected from being damaged by static electricity, and the thickness of the protective layer 20 required is relatively thin.
[0074] In the embodiments of the present application, the display panel 100 has the first organic layer 71 on the side of the encapsulation layer 13 away from the substrate 11, the first organic layer 71 has a relatively thin thickness; the protection layer 20 is arranged on the bending portion 10B, at least one sub-film layer of the protection layer 20 comprises the same material as the first organic body 71a, that is, the first organic layer 71 is extended from the display portion 10A to the bending portion 10B, not only making the bending portion 10B have a small bending radius, but also protecting the wires of the bending portion 10B from being damaged by static electricity. Further, at least one sub-film layer of the protection layer 20 comprises the second organic body 20a and the plurality of conductive particles 20b distributed in the second organic body 20a, through the arrangement of the conductive particles 20b, the wires of the bending portion 10B can be better protected from being damaged by static electricity, and the thickness of the required protection layer 20 is relatively thin.
[0075] In some embodiments, as shown in Figure 1 and Figure 2 , the display panel 100 further comprises a touch layer 14, the touch layer 14 comprises a touch functional layer 141 and a touch flat layer 142, the touch functional layer 141 is located on the side of the encapsulation layer 13 away from the substrate 11, and the touch flat layer 142 is located on the side of the touch functional layer 141 away from the substrate 11, wherein the first organic layer 71 is the touch flat layer 142.
[0076] For example, the touch functional layer 141 can comprise a plurality of touch electrodes to realize the touch function of the display panel 100, for example, the touch functional layer 141 can comprise a plurality of touch sensing electrodes and a plurality of touch driving electrodes, and the structure of the touch functional layer 141 is not limited here.
[0077] For example, the touch flat layer 142 is located on the side of the touch functional layer 141 away from the substrate 11, and the touch flat layer 142 can flatten the surface of the touch functional layer 141 away from the substrate 11, to facilitate the subsequent manufacturing process.
[0078] For example, the first organic layer 71 is the touch flat layer 142, and the touch flat layer 142 can be extended from the display portion 10A to the bending portion 10B to protect the bending portion 10B.
[0079] In some embodiments, as shown in Figure 3 and Figure 4 , the display panel 100 further comprises a light filtering functional layer 15, the light filtering functional layer 15 comprises a color resistance layer 151 and a light filtering flat layer 152, the color resistance layer 151 is located on the side of the encapsulation layer 13 away from the substrate 11, and the light filtering flat layer 152 is located on the side of the color resistance layer 151 away from the substrate 11, wherein the first organic layer 71 is the light filtering flat layer 152.
[0080] For example, the color resist layer 151 can include a plurality of color resist blocks and a black matrix (BM) including a plurality of black matrix openings, the color resist blocks being disposed at least within corresponding black matrix openings. The color resist blocks can filter light emitted by corresponding light emitting devices. By disposing the light filtering flat layer 15, a polarizing plate in the display panel 100 can be removed, thereby reducing the thickness and cost of the display panel 100.
[0081] For example, the light filtering flat layer 152 is disposed on a side of the color resist layer 151 distal from the substrate 11, and the light filtering flat layer 152 can planarize a surface of the color resist layer 151 distal from the substrate 11, to facilitate subsequent manufacturing processes.
[0082] For example, the first organic layer 71 is the light filtering flat layer 152, and the light filtering flat layer 152 can extend from the display portion 10A to the bending portion 10B to protect the bending portion 10B.
[0083] In some embodiments, as shown in FIGS. 1A and 1B, the first organic layer 71 is the light filtering flat layer 152, and the light filtering flat layer 152 can extend from the display portion 10A to the bending portion 10B to protect the bending portion 10B. Figure 1 and Figure 2 For example, as shown in FIGS. 1A and 1B, the first organic layer 71 is the light filtering flat layer 152, and the light filtering flat layer 152 can extend from the display portion 10A to the bending portion 10B to protect the bending portion 10B. Figure 3 and Figure 4 For example, as shown in FIGS. 1A and 1B, the first organic layer 71 is the light filtering flat layer 152, and the light filtering flat layer 152 can extend from the display portion 10A to the bending portion 10B to protect the bending portion 10B.
[0084] For example, as shown in FIGS. 1A and 1B, the first organic layer 71 is the light filtering flat layer 152, and the light filtering flat layer 152 can extend from the display portion 10A to the bending portion 10B to protect the bending portion 10B. Figure 1 and Figure 2 For example, as shown in FIGS. 1A and 1B, the first organic layer 71 is the light filtering flat layer 152, and the light filtering flat layer 152 can extend from the display portion 10A to the bending portion 10B to protect the bending portion 10B.
[0085] For example, as shown in FIGS. 1A and 1B, the first organic layer 71 is the light filtering flat layer 152, and the light filtering flat layer 152 can extend from the display portion 10A to the bending portion 10B to protect the bending portion 10B. Figure 1 and Figure 2 For example, as shown in FIGS. 1A and 1B, the first organic layer 71 is the light filtering flat layer 152, and the light filtering flat layer 152 can extend from the display portion 10A to the bending portion 10B to protect the bending portion 10B.
[0086] For example, as shown in FIGS. 1A and 1B, the first organic layer 71 is the light filtering flat layer 152, and the light filtering flat layer 152 can extend from the display portion 10A to the bending portion 10B to protect the bending portion 10B. Figure 3 and Figure 4As shown, the first organic layer 71 is a light-filtering planarization layer 152. The material of the first organic layer 71 only includes the first organic body 71a (excluding conductive particles). The first protective layer 21 includes the 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, such as Figure 3 and Figure 4 When manufacturing the light-filtering planarization layer 152, the light-filtering planarization layer 152 extends to the bending portion 10B to form a first protective layer 21. The light-filtering planarization layer 152 in the display portion 10A only includes the first organic body 71a (excluding conductive particles). The light-filtering planarization layer 152 simultaneously forms a 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 implementations, such as Figure 5 As shown, or as Figure 6 As shown, the protective layer 20 includes a first protective layer 21, which 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. The first organic layer 71 also includes a plurality of conductive particles 20b distributed in the first organic body 71a.
[0089] For example, such as Figure 5 As shown, when manufacturing the touch planarization layer 142, the touch planarization layer 142 is a first organic layer 71. The touch planarization layer 142 extends to the bending portion 10B to form a first protective layer 21. The touch planarization 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 planarization 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, which can better play the role of electrostatic protection in the bending portion 10B.
[0090] For example, such as Figure 6 As shown, when manufacturing the light-filtering planarization layer 152, the light-filtering planarization layer 152 is a first organic layer 71.
