DETAILED DESCRIPTION

[0050] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0051] Referring to Figure 5 , a display panel disclosed in an embodiment of the present application is shown, which includes a display module 10, a cover plate 20 and a support layer 30.

[0052] Specifically, in the embodiments of the present application, the display panel includes at least one bending area A1 and a non-bending area A2 located on at least one side of the bending area A1. For example, referring to Figure 1 and Figure 2 , for a U-shaped bending display panel, one bending area A1 and non-bending areas A2 located on both sides of the bending area A1 can be included; referring to Figure 3 and Figure 4 , for a water drop-shaped bending display panel, three bending areas A1 and non-bending areas A2 located on at least one side of each bending area A1 can be included.

[0053] The display module 10 is a part of the display panel that emits light. The display module 10 can specifically include a substrate, a driving circuit layer, a light-emitting layer, and the like disposed on the substrate. The driving circuit layer can drive the light-emitting layer to emit light, thereby realizing the display of image content.

[0054] Referring to Figure 5 As shown in FIG. 1, the cover plate 20 is disposed on the light-emitting side of the display module 10. The cover plate 20 and the display module 10 can be connected by a first adhesive layer 71. The cover plate 20 can provide protection for the entire display panel. It can be understood that, since the display panel of the present application is a flexible display panel, the cover plate 20 should also have bending capability, i.e., the cover plate 20 is made of a flexible material. For example, the cover plate 20 can be made of a polyimide material.

[0055] In an embodiment, referring to Figure 5 As shown in FIG. 1, a polarizing layer 40 can be disposed between the cover plate 20 and the display module 10. The polarizing layer 40 can improve the light-emitting effect of the display panel. The cover plate 20 and the polarizing layer 40 can be connected by the first adhesive layer 71, and the polarizing layer 40 and the display module 10 can be connected by a second adhesive layer 72.

[0056] Referring to Figure 5 As shown in FIG. 1, the support layer 30 is disposed on the backlight side of the display module 10. In the present application, the support layer 30 is made of a metal material. The support layer 30 is mainly used to improve the flatness and impact resistance of the display panel. The material of the support layer 30 can include stainless steel, copper alloy, aluminum alloy, magnesium alloy, titanium alloy, or a composite material mainly composed of metal. The thickness of the support layer 30 is greater than or equal to 0.01 mm and less than or equal to 0.05 mm. For example, the thickness of the support layer 30 can be 0.01 mm, 0.02 mm, 0.03 mm, 0.04 mm, 0.05 mm, or the like. The thickness of the support layer 30 can be set according to actual needs.

[0057] In order to improve the bending capability of the support layer 30 made of a metal material, the structure of the support layer 30 is optimized in the present application.

[0058] Specifically, referring to Figure 8As shown, the support layer 30 is generally rectangular in shape, and thus the support layer 30 can include two first edges 31 parallel to each other and two second edges 32 parallel to each other, wherein the length direction of the first edges 31 is perpendicular to the length direction of the second edges 32, the length of the first edges 31 is greater than the length of the second edges 32, and the two first edges 31 and the two second edges 32 are connected two by two. That is, the first edges 31 are the long sides of the rectangular support layer 30, the second edges 32 are the short sides of the rectangular support layer 30, the length of the first edges 31 is the length of the support layer 30, and the length of the second edges 32 is the width of the support layer 30.

[0059] Meanwhile, the length direction of the first edges 31 is perpendicular to the length direction of the bending axis of the bending area A1 of the display panel. In the embodiment, the first edges 31 can be divided into a first part 311 located in the bending area A1 and a second part 312 of the non-bending area A2. The display panel has a bending area A1 and non-bending areas A2 located on both sides of the bending area A1, and thus the first edges 31 include the first part 311 and the second part 312 located at both ends of the first part 311.

[0060] The distance between the first parts 311 of the two first edges 31 is less than the distance between the second parts 312 of the two first edges 31. The distance between the first parts 311 of the two first edges 31 can be understood as the width of the support layer 30 in the bending area A1, and the distance between the second parts 312 of the two first edges 31 can be understood as the width of the support layer 30 in the non-bending area A2. Therefore, in the embodiment, the first edges 31 of the support layer 30 are inwardly recessed in the bending area A1 relative to the non-bending area A2. This can reduce the width of the support layer 30 in the bending area A1, thereby improving the tensile strength of the support layer 30 and further improving the bending capability of the support layer 30.

[0061] Meanwhile, referring to Figure 5 As shown, in the embodiment, the display panel can include a support plate 50 and at least one support film 60 in addition to the support layer 30. The support plate 50 is located at the bottom layer of the entire display panel, and the support plate 50 can be made of aluminum or stainless steel to provide support for the entire display panel. In an embodiment, in order to improve the bending capability of the support plate 50, a through hole can be formed in the support plate 50 corresponding to the position of the bending area A1 of the display panel.

[0062] The support film 60 is mainly used to improve the structural strength of the entire display panel, and the material of the support film 60 can be selected from polyimide (PI) or polyethylene terephthalate (PET).

[0063] Referring to Figure 6As shown, when the support film 60 is provided with one layer, the support film 60 is located between the support layer 30 and the support plate 50, and the support film 60 and the support plate 50 are connected through the fifth adhesive layer 75, the support film 60 and the support layer 30 are connected through the fourth adhesive layer 74, and the support layer 30 and the display module 10 are connected through the third adhesive layer 73.

[0064] Referring to Figure 7 As shown, when the support film 60 is provided with two layers, the first support film 61 is located between the support film 60 and the display module 10, and the second support film 62 is located between the support layer 30 and the support plate 50; one side of the first support film 61 is connected with the display module 10 through the third adhesive layer 73, and the other side is connected with the support layer 30 through the fourth adhesive layer 74; one side of the second support film 62 is connected with the support layer 30 through the fifth adhesive layer 75, and the other side is connected with the support plate 50 through the sixth adhesive layer 76.

[0065] That is, the first adhesive layer and the second adhesive layer are always provided on both sides of the support layer 30. Among them, when the support film 60 is provided with one layer, the third adhesive layer 73 is the first adhesive layer, and the fourth adhesive layer 74 is the second adhesive layer; when the support film 60 is provided with two layers, the fourth adhesive layer 74 is the first adhesive layer, and the fifth adhesive layer 75 is the second adhesive layer.

[0066] Referring to Figure 8 As shown, since the first edge 31 of the support layer 30 is inwardly recessed in the bending area A1 relative to the non-bending area A2, the first adhesive layer and the second adhesive layer on both sides can include the first edge 31 of the support layer 30 in the bending area A1, so that the deformation of the first edge 31 of the support layer 30 in the bending area A1 can be close to the deformation of the adhesive layer, thereby releasing the actual stress of the first edge 31 of the support layer 30 in the bending area A1, and improving the bending reliability of the support layer 30.

[0067] In addition, the absolute value of the difference between the interval between the first part 311 of the two first edges 31 of the support layer 30 and the interval between the second part 312 of the two first edges 31 is greater than or equal to 0.1mm and less than or equal to 1.0mm. The absolute value is the size of the first edge 31 of the support layer 30 inwardly recessed in the bending area A1 relative to the non-bending area A2. Exemplarily, the absolute value can be 0.1mm, 0.2mm, 0.5mm, 0.7mm, 1.0mm, etc., which can be set according to actual needs by those skilled in the art.

[0068] Through the above-mentioned display panel provided by the embodiment of the present application, the part of the two first edges 31 of the support layer 30 located in the bending area A1 is inwardly recessed relative to the non-bending area A2, so that the width of the support layer 30 in the bending area A1 is reduced, thereby improving the bending reliability of the support layer 30.

[0069] Referring to Figure 9 As shown in the figure, in an embodiment, the edge sealing glue 80 can also be coated on both sides of the support layer 30 and the glue layer, and the edge sealing glue 80 at least covers the two sides of the first edge of the support layer 30. In this way, the deformation of the first edge 31 of the support layer 30 in the bending area A1 can be close to the deformation of the glue layer, thereby releasing the actual stress of the first edge 31 of the support layer 30 in the bending area A1, and improving the bending reliability of the support layer 30.

[0070] Referring to Figure 10 As shown in the figure, in an alternative embodiment, the embodiment of the present application also provides a display panel, in which the first part 311 and the second part 312 of the first edge 31 have a transition connection section 313 therebetween.

[0071] Specifically, one end of the transition connection section 313 is connected with the first part 311, and the other end is connected with the second part 312, and the spacing between the two transition connection sections 313 corresponding to the first edges 31 gradually increases or gradually decreases. That is, the width of the support layer 30 in the transition connection section 313 gradually increases or gradually decreases. For example, from left to right, the first edge 31 of the support layer 30 is in turn the second part 312, the first part 311 and the second part 312, and the width of the support layer 30 in the transition connection section 313 gradually decreases from the left second part 312 to the first part 311; and the width of the support layer 30 in the transition connection section 313 gradually increases from the first part 311 to the right second part 312. The provision of the transition connection section 313 can prevent the stress of the first edge 31 of the support layer 30 from suddenly changing at the positions of the bending area A1 and the non-bending area A2 during the bending process, thereby ensuring the bending strength of the support layer 30.

[0072] Referring to Figure 11 As shown in the figure, in an alternative embodiment, the embodiment of the present application also provides a display panel, in which the support layer 30 is provided with a plurality of openings 33 in the bending area A1.

[0073] Specifically, the plurality of openings 33 are distributed along the length direction of the bending axis, and the openings 33 penetrate the support layer 30. In the embodiment of the present application, the openings 33 are provided as strip-shaped holes, that is, the openings 33 have a certain length, and the length direction of the openings 33 is perpendicular to the length direction of the bending axis. In this way, the support layer 30 in the bending area A1 can be divided into a plurality of parallel strips, that is, the actual width of the support layer 30 in the bending area A1 is reduced, thereby reducing the edge stress of the support layer 30 during the bending process, reducing the risk of fracture of the first edge 31, and improving the bending reliability of the support layer 30.

[0074] Meanwhile, by making the length direction of the opening 33 perpendicular to the length direction of the bending axis, the support layer 30 can have a larger solid area ratio and greater rebound force in the bending area A1, which is more conducive to improving the impact resistance and rebound force of the display panel, while also taking into account the bending reliability of the support layer 30.

[0075] It is understandable that the rebound force of the support layer 30 can be adjusted by adjusting the number and width of the openings 33, that is, by adjusting the ratio of the width of the openings 33 to the width of the support layer 30.

[0076] Reference Figure 11 As shown, in one embodiment, the length of the opening 33 is greater than the width of the bending region A1. That is, in this embodiment, the length of the opening 33 is greater than the length of the area in the support layer 30 that actually participates in bending, which can better improve the bending resistance of the support layer 30.

[0077] Reference Figure 12 As shown, in one embodiment, the width of the two end regions of the opening 33 can be greater than the width of the middle region of the opening 33. This creates a concave shape at the edge of the opening 33 along its length, which reduces stress concentration at the first edge 31 of the support layer 30 during bending, thus improving the bending reliability of the support layer 30.

[0078] Reference Figure 13 As shown, in one optional embodiment, this application also provides a display panel, which includes a first bending area A11, a second bending area A12 and a third bending area A13.

[0079] Specifically, the display panel is a teardrop-shaped bent display panel, meaning that after bending, the bent portion of the display panel takes on a teardrop shape. The display panel has a first bending area A11, a second bending area A12, and a third bending area A13. The second bending area A12 and the third bending area A13 are located on either side of the first bending area A11, and both sides of the second bending area A12 and the third bending area A13 are connected to non-bending areas A2. In other words, the first bending area A11 and the second bending area A12, as well as the first bending area A11 and the third bending area A13, are connected via non-bending areas A2. Furthermore, the side of the second bending area A12 furthest from the first bending area A11, and the side of the third bending area A13A1 furthest from the first bending area A11, are connected to non-bending areas A2.

[0080] In the support layer 30 of the display panel, the first edge 31 of the support layer 30 includes a plurality of first portions 311 located in each bending area A1 respectively and a plurality of second portions 312 located in each non-bending area A2 respectively. From left to right, the first edge 31 includes the second portion 312, the first portion 311, the second portion 312, the first portion 311, the second portion 312, the first portion 311 and the second portion 312 in turn.

[0081] Further, the interval between the corresponding first portions 311 of the two first edges 31 is smaller than the interval between the corresponding second portions 312 of the two first edges 31, that is, the width of the support layer 30 in the first bending area A11, the second bending area A12 and the third bending area A13 is smaller than the width of the support layer 30 in the non-bending area A2. Further, the retracted distance of the first edge 31 in the first bending area A11, the second bending area A12 and the third bending area A13 can be equal or not equal.

[0082] In this way, the width of the support layer 30 in the first bending area A11, the second bending area A12 and the third bending area A13 can be reduced, so as to reduce the edge stress in the bending process of the support layer 30, reduce the risk of fracture of the first edge 31 and improve the bending reliability of the support layer 30.

[0083] Referring to Figure 14 In an embodiment, in order to better improve the bending reliability of the support layer 30, a plurality of openings 33 are formed in the first bending area A11 of the support layer 30, the plurality of openings 33 are distributed along the length direction of the bending axis, the openings 33 penetrate through the support layer 30, and the length direction of the openings 33 is perpendicular to the length direction of the bending axis. In this way, the support layer 30 in the first bending area A11 can be divided into a plurality of parallel strips, that is, the actual width of the support layer 30 in the bending area A1 is reduced, so as to reduce the edge stress in the bending process of the support layer 30, reduce the risk of fracture of the first edge 31 and improve the bending reliability of the support layer 30.

[0084] Referring to Figure 15 and Figure 16 In an embodiment, a plurality of openings 33 are formed in the first bending area A11, the second bending area A12 and the third bending area A13 of the support layer 30, the plurality of openings 33 in each bending area A1 are distributed along the length of the corresponding bending axis, the openings 33 penetrate through the support layer 30, and the length direction of the openings 33 is perpendicular to the length direction of the bending axis. In this way, the actual width of the support layer 30 in each bending area A1 is reduced, so as to better improve the bending performance of the support layer 30.

[0085] Meanwhile, in this embodiment, the interval between the openings 33 in the first bending area A11 and the interval between the openings 33 in the second bending area A12 and the third bending area A13 can be adjusted according to actual needs.

[0086] For example, referring to Figure 15 in this embodiment, the interval between the two adjacent openings 33 in the first bending area A11 can be the same as the interval between the two adjacent openings 33 in the second bending area A12 and the third bending area A13. In this way, the bending performance of the support layer 30 in each bending area A1 can be effectively guaranteed, and the openings 33 can be formed in each bending area A1 at the same time, so as to simplify the preparation steps of the support layer 30.

[0087] For example, referring to Figure 16 in another embodiment of this embodiment, the interval between the two adjacent openings 33 in the first bending area A11 is different from the interval between the two adjacent openings 33 in the second bending area A12 and the third bending area A13. For example, the interval between the two openings 33 in the first bending area A11 can be smaller than the interval between the two adjacent openings 33 in the second bending area A12 and the third bending area A13. In this way, the bending performance of the support layer 30 in each bending area A1 can be different, so as to better adapt to different bending conditions.

[0088] For example, referring to Figure 17 in an optional embodiment, the embodiment of the present application also provides a display panel, in which the first portion 311 is arranged in an arc shape, and the notch of the arc-shaped first portion 311 faces the inside of the support layer 30.

[0089] Specifically, the notch of the arc-shaped portion faces the support layer 30, and it can also be understood that the first portion 311 is generally in an outward convex arc shape. In this way, arranging the first portion 311 as an arc shape that protrudes outward from the outside of the support layer 30 can better improve the stress concentration of the first edge 31 in the bending area A1, thereby better improving the bending reliability of the support layer 30.

[0090] Based on the same inventive concept, the embodiment of the present application discloses a display device, which comprises any one of the display panels described in the foregoing of the embodiment of the present application.

[0091] Specifically, the display device can include a computer display, a television, a billboard, a laser printer with display function, a telephone, a mobile phone, a personal digital assistant (PDA), a laptop computer, a digital camera, a camcorder, a viewfinder, a vehicle, a large-area wall, a screen of a theater or a sports stadium sign, etc.
