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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] As mentioned in the background technology section, in order to achieve a narrow frame and a high screen-to-body ratio of the display panel, the display panel in the related art usually binds a bendable flexible circuit board around the array substrate in the OLED (Organic Light-Emitting Diode) module. Figure 1 As shown, Figure 1 The cross-sectional schematic diagram of a display panel provided in the related art includes an array substrate 11', a flexible circuit board 12', a light-emitting device layer 13', an encapsulation layer 14' and a cover plate 15', wherein the base of the array substrate 11' is a rigid base. Since one side of the array substrate 11' in the related art is a straight structure, and the bending area of ​​the flexible circuit board 12' is an arc structure, there is a space between one side of the array substrate 11' and the flexible circuit board 12'. Based on this, in the related art, the sealing is usually performed at the bending inner diameter position of the flexible circuit board 12', and the sealing type can be a UV curing UV glue 16' with a high elastic modulus. The UV glue has a high hardness after curing, which affects the bending of the flexible circuit board. The UV glue is a liquid glue, and there is a phenomenon of uneven sealing, which causes the sealing glue to be unable to fit tightly with the side of the array substrate. Therefore, during the bending process of the flexible circuit board, the boundary between the sealing part area and the array substrate will peel (peel off), resulting in the failure of RA (reliability) reliability verification. Therefore, the current display panel has the problem of low reliability.

[0033] Based on the above technical problems, the embodiments of the present application provide a display panel and a display device, which are intended to improve the reliability of the display panel by changing the shape of the array substrate. Specifically, the display panel provided by the embodiments of the present application includes an array substrate and a flexible circuit board, the array substrate includes a rigid substrate and an array film layer, the array substrate includes a first surface, a second surface and a curved surface, the first surface and the second surface are located on opposite sides of the thickness direction of the array substrate, the curved surface is arranged on one side of the array substrate along the first direction, and connects the first surface and the second surface; the first direction is perpendicular to the thickness direction of the array substrate; the flexible circuit board covers part of the first surface, part of the second surface and at least part of the curved surface. By adopting the above technical solution, by setting one surface of the array substrate as a curved surface, and covering the flexible circuit board on at least part of the curved surface, it can be ensured that the shape of the curved surface is approximately consistent with the shape of the bending area of ​​the flexible circuit board, so that the curved surface can be ensured to be closely fitted with the flexible circuit board, thereby improving the connection stability of the flexible circuit board and the array substrate, so that the reliability of the display panel can be improved.

[0034] 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.

[0035] Figure 2 A cross-sectional schematic diagram of a display panel provided in an embodiment of the present application. Figure 2 As shown, the display panel 10 provided in the embodiment of the present application includes an array substrate 11 and a flexible circuit board 12, wherein the array substrate 11 includes a rigid substrate and an array film layer, the material of the rigid substrate may be glass, and the array film layer refers to a film layer structure including a pixel driving circuit and a signal line. In addition, the embodiment of the present application has no limitation on the hardness, thickness and cutting process of the array substrate 11.

[0036] The array substrate 11 includes a first surface 111, a second surface 112 and a curved surface 113. The first surface 111 and the second surface 112 are located on opposite sides of the thickness direction of the array substrate 11. The curved surface 113 is located on one side of the array substrate 11 along the first direction X, and the curved surface 113 connects the first surface 111 and the second surface 112. The first direction X is perpendicular to the thickness direction of the array substrate 11. Optionally, the cross-sectional shape of the curved surface 113 may be an arc shape; or, the cross-sectional shape of the curved surface 113 may also be similar to an arc shape, for example, the curved surface 113 may also be a quasi-arc surface, that is, the curved surface is formed by connecting a plurality of short line segments at different angles. It can be understood that the curved surface 113 in the embodiment of the present application may not be an arc surface in an absolute sense, and the shape of the curved surface 113 may be actually set according to the cutting technology.

[0037] For the flexible circuit board 12, optionally, the flexible circuit board 12 may only cover part of the curved surface 113; or, the flexible circuit board 12 may only cover the entire curved surface 113; or, the flexible circuit board 12 may also cover part of the first surface 111 and at least part of the curved surface 113; or, the flexible circuit board 12 may also cover part of the second surface 112 and at least part of the curved surface 113; or, the flexible circuit board 12 may also cover part of the first surface 111, part of the second surface 112 and at least part of the curved surface 113. Of course, the embodiment of the present application does not limit the specific setting position of the flexible circuit board 12.

[0038] In addition, combined Figure 2 As shown, the display panel 10 may further include a light emitting device layer 13 , an encapsulation layer 14 , and a cover plate 15 stacked on the array substrate 11 , wherein the cover plate 15 may be made of glass.

[0039] In summary, the display panel 10 provided in the embodiment of the present application sets one surface of the array substrate as a curved surface, and covers the flexible circuit board on at least part of the curved surface. In this way, it can be ensured that the shape of the curved surface is approximately consistent with the shape of the bending area of ​​the flexible circuit board, thereby ensuring that the curved surface and the flexible circuit board are closely fitted, thereby improving the connection stability between the flexible circuit board and the array substrate, and thus improving the reliability of the display panel.

[0040] Since the array substrate 11 includes the arc surface 113 , the optional specific structure of the arc surface 113 is described below.

[0041] In some embodiments, Figure 3 As shown, Figure 3 A schematic cross-sectional view of an arc surface provided in an embodiment of the present application, wherein the arc surface 113 includes a first end 113a and a second end 113b arranged opposite to each other in the circumference, wherein the first end 113a is connected to the first surface 111, and the second end 113b is connected to the second surface 112, and the line between the first end 113a and the center O of the arc surface 113 is L1, and the line between the second end 113b and the center O of the arc surface 113 is L2, and the angle between the line L1 between the first end 113a and the center O of the arc surface 113 and the line L2 between the second end 113b and the center O of the arc surface 113 is less than or equal to 180 degrees. In this way, by setting the shape of the arc surface in the array substrate to be approximately consistent with the arc shape of the bending area of ​​the flexible circuit board, it is possible to ensure that the arc surface is closely attached to the flexible circuit board, thereby improving the connection stability between the flexible circuit board and the array substrate, and thus improving the reliability of the display panel.

[0042] In one embodiment, reference Figure 3 As shown, Figure 3The angle between the line L1 connecting the first end 113a and the center O of the arc surface 113 and the line L2 connecting the second end 113b and the center O of the arc surface 113 is less than 180 degrees.

[0043] In another embodiment, referring to Figure 4 As shown, Figure 4 A schematic cross-sectional view of another curved surface provided in an embodiment of the present application, Figure 4 The angle between the line L1 connecting the first end 113a and the center O of the arc surface 113 and the line L2 connecting the second end 113b and the center O of the arc surface 113 is equal to 180 degrees, that is, Figure 4 The circumferential shape of the middle arc surface 113 is semicircular.

[0044] In one embodiment, the radius of the arc surface 113 ranges from 0.2 mm to 0.6 mm, which means that the length of the line segment from the center O of the arc surface 113 to any point on the arc surface 113 is 0.2 mm to 0.6 mm. It is understandable that the embodiment of the present application can cut the boundary of the array substrate 11 in the rigid OLED into an arc shape by CNC (Computerized Numerical Control) profiling cutting technology, imitating the shape of the bending area of ​​the flexible circuit board 12. Under the limitations of the cutting equipment accuracy and the thickness of the array substrate 11, the embodiment of the present application can cut the radius of the arc surface 113 to between 0.2 mm and 0.6 mm, referring to Figure 5 As shown, Figure 5 A cross-sectional schematic diagram of a display panel including an arc radius is provided for an embodiment of the present application, wherein the radius R of the arc surface 113 is 0.2 mm, and the thickness of the flexible circuit board 12 is less than 0.1 mm, so it can be determined that the protrusion L of the bending area of ​​the flexible circuit board 12 is less than 0.3 mm. Therefore, compared with the related art in which the bending area of ​​the flexible circuit board 12 has a protrusion of at least 0.6 mm, the embodiment of the present application can reduce the protrusion of the bending area of ​​the flexible circuit board 12 from 0.6 mm to less than 0.3 mm, thereby greatly narrowing the module frame and better meeting the user's demand for further narrowing of the module frame.

[0045] In addition, in the embodiment of the present application, the first end 113a and the second end 113b of the arc surface 113 can be polished after cutting to ensure that the connection between the arc surface 113 and the first surface 111 and the second surface 112 is in a smooth state, so that the flexible circuit board can be more conveniently covered on part of the first surface 111, part of the second surface 112 and at least part of the arc surface 113.

[0046] In some embodiments, reference Figure 6 As shown, Figure 6A cross-sectional schematic diagram of a display panel including a connection layer provided in an embodiment of the present application, wherein the display panel 10 further includes a connection layer 14, and the connection layer 14 is disposed between the array substrate 11 and the flexible circuit board 12. It is understood that the connection layer 14 may include but is not limited to any kind of sealing glue, such as liquid glue, solid glue, etc. Optionally, the liquid glue may include but is not limited to UV curing UV glue, etc., and the solid glue may include but is not limited to conductive glue, strong glue, etc. Of course, the embodiment of the present application does not limit the material and amount of the sealing glue. In this way, by providing the connection layer 14 between the array substrate 11 and the flexible circuit board 12, the array substrate 11 and the flexible circuit board 12 can be bonded through the connection layer 14, so that the arc surface can be more closely fitted with the bending area of ​​the flexible circuit board, and the sealing glue space in the related technology is saved, and the diffusion path of water vapor is more completely blocked, so that the reliability of the display panel can be further improved.

[0047] In one embodiment, the connection layer 14 includes solid glue. Optionally, the solid glue may include but is not limited to any solid sealing glue such as conductive glue and super glue. Since solid glue has better hysteresis than liquid glue, the embodiment of the present application uses solid glue, which can be more evenly sealed between the bending area of ​​the array substrate 11 and the flexible circuit board 12, thereby achieving a better bonding effect.

[0048] In one embodiment, the solid glue includes a conductive glue, wherein the conductive glue may be an ACF (Anisotropic Conductive Film). Since conductive glue is usually used for sealing between the non-bending regions of the array substrate 11 and the flexible circuit board 12, the embodiment of the present application also uses conductive glue for sealing between the bending regions of the array substrate 11 and the flexible circuit board 12, which can ensure the consistency of the materials of the connection layer, is more convenient, and can ensure that there is no repulsion between the sealing glues.

[0049] In one embodiment, the thickness of the connection layer 14 is less than or equal to 20 microns. In this way, even if the connection layer is added, it will not have a significant impact on the protrusion of the bending area in the flexible circuit board 12, that is, the embodiment of the present application can still greatly narrow the module frame, and can better meet the user's demand for further narrowing the module frame.

[0050] In one embodiment, reference Figure 7 As shown, Figure 7A top view of a display panel after bending a flexible circuit board is provided in an embodiment of the present application, wherein the size of the connection layer 14 in the second direction Y is consistent with the size of the flexible circuit board 12 in the second direction Y, wherein the first direction X intersects with the second direction Y, and the first direction X is perpendicular to the thickness direction of the array substrate, and the second direction Y is also perpendicular to the thickness direction of the array substrate. It should be noted that the "consistent" described in the embodiment of the present application does not only mean absolute equality, but may also have a certain error. In this way, by making the size of the connection layer 14 in the second direction Y consistent with the size of the flexible circuit board 12 in the second direction, it can be further ensured that the bending area of ​​the flexible circuit board 12 and the curved boundary of the array substrate 11 can be closely fitted with each other, thereby achieving a better bonding effect and further improving the reliability of the display panel.

[0051] In some embodiments, the connection layer 14 at least covers the curved surface 113. That is, it can be understood that, optionally, the connection layer 14 can be only disposed between the entire curved surface 113 and the flexible circuit board 12; or, the connection layer 14 can also be disposed between a portion of the first surface 111 and the flexible circuit board 12, and between the entire curved surface 113 and the flexible circuit board 12; or, the connection layer 14 can also be disposed between a portion of the second surface 112 and the flexible circuit board 12, and between the entire curved surface 113 and the flexible circuit board 12; or, the connection layer 14 can also be disposed between a portion of the first surface 111 and the flexible circuit board 12, and between a portion of the second surface 112 and the flexible circuit board 12, and between the entire curved surface 113 and the flexible circuit board 12. Of course, the embodiment of the present application does not limit the specific location of the connection layer 14.

[0052] In one embodiment, reference Figure 8 As shown, Figure 8 A top view of a display panel when a flexible circuit board is in an unfolded state provided in an embodiment of the present application, at this time, the above-mentioned connection layer 14 only covers the curved surface, that is, it can be understood that the above-mentioned connection layer 14 can be only arranged between the entire curved surface 113 of the array substrate 11 and the flexible circuit board 12, that is, the size of the above-mentioned connection layer 14 in the second direction Y is consistent with the size of the flexible circuit board 12 in the second direction Y, and the size of the above-mentioned connection layer 14 in the first direction X is at least consistent with the unfolded size of the curved surface of the array substrate 11 in the first direction X.

[0053] In one embodiment, the connection layer also covers the first surface and / or the second surface, that is, it can be understood that, optionally, reference Fig. 9 As shown, Fig. 9Another embodiment of the present application provides a top view of a display panel when the flexible circuit board is in an unfolded state. At this time, the connection layer 14 can be arranged not only between the entire curved surface 113 of the array substrate 11 and the flexible circuit board 12, but also between at least part of the first surface 111 and the flexible circuit board 12. For example, Fig. 9 As shown, the connection layer 14 covers the entire curved surface 113 and the first surface 111 of the array substrate 11; alternatively, the connection layer 14 can be disposed not only between the entire curved surface 113 of the array substrate 11 and the flexible circuit board 12, but also between at least a portion of the second surface 112 and the flexible circuit board 12; alternatively, the connection layer 14 can be disposed not only between the entire curved surface 113 of the array substrate 11 and the flexible circuit board 12, but also between at least a portion of the first surface 111 and the flexible circuit board 12, and between at least a portion of the second surface 112 and the flexible circuit board 12.

[0054] In some embodiments, a plurality of sub-surfaces arranged along the second direction Y of the arc surface may also be introduced.

[0055] In one embodiment, reference Fig.10 As shown, Fig.10 Another top view of a display panel after bending the flexible circuit board is provided in an embodiment of the present application, wherein the second direction Y intersects with the first direction X, and the first direction X is perpendicular to the thickness direction of the array substrate, and the second direction Y is also perpendicular to the thickness direction of the array substrate. It should be noted that: Fig.10 The arc surface 113 shown in the figure refers to the arc surface in the top view along the thickness direction of the array substrate. The arc surface 113 includes a first sub-surface 1131, a second sub-surface 1132 and a third sub-surface 1133 arranged along the second direction Y, the first sub-surface 1131 is arranged between the second sub-surface 1132 and the third sub-surface 1133, and the flexible circuit board 12 covers the first sub-surface 1131 in the arc surface 113, that is, it can be understood that the side surfaces along the thickness direction of the array substrate 11 in the above array substrate 11 are all arc surfaces 113, that is, in this embodiment, the side surfaces of the array substrate 11 in the thickness direction can be arc-cut, and the flexible circuit board 12 only covers the first sub-surface 1131 in the arc surface 113 of the array substrate 11, that is, the flexible circuit board 12 does not completely cover the entire arc surface 113, so that the flexible circuit board can only cover the required part of the arc surface, which can save the covering cost of the flexible circuit board.

[0056] In another embodiment, referring to Fig.11 As shown, Fig.11Another top view of a display panel after bending the flexible circuit board is provided in an embodiment of the present application, wherein the second direction Y intersects with the first direction X, and the first direction X is perpendicular to the thickness direction of the array substrate, and the second direction Y is also perpendicular to the thickness direction of the array substrate. It should be noted that: Fig.11 The arc surface 113 shown in the figure refers to the arc surface in the top view along the thickness direction of the array substrate. The array substrate 11 also includes a first side surface 114 and a second side surface 115. The first side surface 114, the second side surface 115 and the arc surface 113 are all located on the same side of the array substrate 11, and the first side surface 114 and the second side surface 115 are respectively located on both sides of the arc surface 113 along the second direction Y, wherein the first side surface and the second side surface are flat surfaces. That is, it can be understood that the arc surface 113 is arranged between the first side surface 114 and the second side surface 115, that is, in this embodiment, only part of the side surfaces of the array substrate 11 in the thickness direction can be arc-cut, so that the cutting cost of the array substrate can be saved.

Therefore, the display device 20 also has the beneficial effects of the display panel 10 in the above embodiment, and the similarities can be understood by referring to the above explanation of the display panel 10, which will not be repeated below.
