DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] Reference Figure 5 As shown, a display panel disclosed in an embodiment of the present application includes a display module 10 , a cover plate 20 and a support layer 30 .

[0028] Specifically, in the embodiment of the present application, the display panel includes at least one bending area A1 and a non-bending area A2 located at at least one side of the bending area A1. Figure 1 and Figure 2 As shown, the U-shaped bent display panel may include a bending area A1 and non-bending areas A2 located on both sides of the bending area A1; Figure 3 and Figure 4 As shown, the water drop-shaped bent display panel may include three bending areas A1 and a non-bending area A2 located at at least one side of each bending area A1.

[0029] The display module 10 is the part of the display panel that emits light, and may specifically include a substrate, a driving circuit layer and a light-emitting layer disposed on the substrate, etc. The driving circuit layer may drive the light-emitting layer to emit light, thereby realizing the display of image content.

[0030] Reference Figure 5As shown, the cover plate 20 is disposed on the light-emitting side of the display module 10, and the cover plate 20 and the display module 10 can be connected by a first adhesive layer 71, and the cover plate 20 can provide protection for the entire display panel. It can be understood that since the display panel of the embodiment of the present application is a flexible display panel, the cover plate 20 should also have bending ability, that is, the cover plate 20 is made of a flexible material, and exemplarily, the cover plate 20 can be made of a polyimide material.

[0031] In one embodiment, referring to Figure 5 As shown, a polarizing layer 40 may be provided between the cover plate 20 and the display module 10, and the luminous effect of the display panel may be improved by using the polarizing layer 40. The cover plate 20 and the polarizing layer 40 may be connected by a first adhesive layer 71, and the polarizing layer 40 and the display module 10 may be connected by a second adhesive layer 72.

[0032] Reference Figure 5 As shown, the support layer 30 is arranged on the backlight side of the display module 10. In the embodiment of the present application, the support layer 30 is made of a metal material, and 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 may include metal materials such as stainless steel, copper alloy, aluminum alloy, magnesium alloy, titanium alloy, or a composite material with metal as the main body. The thickness of the support layer 30 is greater than or equal to 0.01mm and less than or equal to 0.05mm. For example, the thickness of the support layer 30 can be 0.01mm, 0.02mm, 0.03mm, 0.04mm, 0.05mm, etc., and those skilled in the art can set it according to actual needs.

[0033] In order to improve the bending ability of the support layer 30 made of metal material, in the embodiment of the present application, the structure of the support layer 30 is optimized.

[0034] Specifically, refer to Figure 8 As shown, the support layer 30 is generally rectangular in shape as a whole, and thus the support layer 30 may 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 edge 31 is perpendicular to the length direction of the second edge 32, the length of the first edge 31 is greater than the length of the second edge 32, and the two first edges 31 and the two second edges 32 are connected in pairs. That is, the first edge 31 is the long side of the rectangular support layer 30, the second edge 32 is the short side of the rectangular support layer 30, the length of the first edge 31 is the length of the support layer 30, and the length of the second edge 32 is the width of the support layer 30.

[0035] At the same time, the length direction of the first edge 31 is perpendicular to the length direction of the bending axis of the bending area A1 of the display panel. In the embodiment of the present application, the first edge 31 can be divided into a first portion 311 located in the bending area A1 and a second portion 312 in 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, so the first edge 31 includes a first portion 311 and second portions 312 located at both ends of the first portion 311.

[0036] Among them, the spacing between the first parts 311 of the two first edges 31 is smaller than the spacing between the second parts 312 of the two first edges 31. The spacing 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 spacing 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 of the present application, the first edge 31 of the support layer 30 is retracted in the bending area A1 relative to the non-bending area A2. In this way, the width of the support layer 30 in the bending area A1 can be reduced, thereby improving the tensile strength of the support layer 30, and further improving the bending ability of the support layer 30.

[0037] At the same time, refer to Figure 5 As shown, in the embodiment of the present application, the display panel may 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 laminated structure of the entire display panel, and the support plate 50 may be made of aluminum or stainless steel to provide support for the entire display panel. In one embodiment, in order to improve the bending ability of the support plate 50, a through hole may be provided on the support plate 50 at a position corresponding to the bending area A1 of the display panel.

[0038] The support film 60 is mainly used to improve the structural strength of the entire display panel. The material of the support film 60 can be polyimide (PI) or polyethylene terephthalate (PET).

[0039] Reference Figure 6 As shown, when only one layer of the support film 60 is provided, 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 by a fifth adhesive layer 75, the support film 60 and the support layer 30 are connected by a fourth adhesive layer 74, and the support layer 30 and the display module 10 are connected by a third adhesive layer 73.

[0040] Reference Figure 7As 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 to the display module 10 through the third adhesive layer 73, and the other side is connected to the support layer 30 through the fourth adhesive layer 74; one side of the second support film 62 is connected to the support layer 30 through the fifth adhesive layer 75, and the other side is connected to the support plate 50 through the sixth adhesive layer 76.

[0041] That is, the first adhesive layer and the second adhesive layer are always provided on both sides of the support layer 30. When only one layer of the support film 60 is provided, the third adhesive layer 73 is the first adhesive layer, and the fourth adhesive layer 74 is the second adhesive layer; when two layers of the support film 60 are provided, the fourth adhesive layer 74 is the first adhesive layer, and the fifth adhesive layer 75 is the second adhesive layer.

[0042] Reference Figure 8 As shown, since the first edge 31 of the support layer 30 is retracted 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 and reducing the actual stress of the first edge 31 of the support layer 30 in the bending area A1, thereby improving the bending reliability of the support layer 30.

[0043] In addition, the absolute value of the difference between the spacing between the first parts 311 of the two first edges 31 of the support layer 30 and the spacing between the second parts 312 of the two first edges 31 is greater than or equal to 0.1 mm and less than or equal to 1.0 mm. This absolute value is also the dimension of the first edge 31 of the support layer 30 that is retracted in the bending area A1 relative to the non-bending area A2. For example, this absolute value can be 0.1 mm, 0.2 mm, 0.5 mm, 0.7 mm, 1.0 mm, etc., and those skilled in the art can set it according to actual needs.

[0044] With the display panel provided in the embodiment of the present application, the first edges 31 on both sides of the portion of the support layer 30 located in the bending area A1 are retracted 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.

[0045] Reference Fig. 9As shown, in one embodiment, 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 first edges on both sides 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 and reducing the actual stress of the first edge 31 of the support layer 30 in the bending area A1, thereby improving the bending reliability of the support layer 30.

[0046] Reference Fig.10 As shown, in an optional implementation, the embodiment of the present application further provides a display panel, in which a transition connection section 313 is provided between the first portion 311 and the second portion 312 of the first edge 31 .

[0047] Specifically, one end of the transition section 313 is connected to the first part 311, and the other end is connected to the second part 312, and the spacing between the transition sections 313 corresponding to the two first edges 31 gradually increases or decreases. In other words, the width of the support layer 30 in the transition section 313 gradually increases or decreases. For example, from left to right, the first edge 31 of the support layer 30 is the second part 312, the first part 311, and the second part 312 in sequence. From the second part 312 on the left to the first part 311, the width of the support layer 30 in the transition section 313 gradually decreases; from the first part 311 to the second part 312 on the right, the width of the support layer 30 in the transition section 313 gradually increases. The setting of the transition section 313 can ensure that the first edge 31 of the support layer 30 will not have a stress mutation problem at the position 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.

[0048] Reference Fig.11 As shown, in an optional implementation, the embodiment of the present application further provides a display panel, in which the support layer 30 is provided with a plurality of openings 33 in the bending area A1.

[0049] Specifically, a 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 arranged as strip 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 arranged strips, that is, the physical 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 the first edge 31 breaking, and improving the bending reliability of the support layer 30.

[0050] At the same time, making the length direction of the opening 33 perpendicular to the length direction of the bending axis can make the support layer 30 have a larger physical area ratio and a larger rebound force in the bending area A1, which is more conducive to improving the impact resistance and rebound force of the display panel while taking into account the bending reliability of the support layer 30.

[0051] 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 .

[0052] Reference Fig.11 As shown, in one embodiment, the length of the opening 33 is greater than the width of the bending area A1. That is, in this embodiment, the length of the opening 33 is greater than the length of the area actually involved in the bending of the support layer 30, which can better improve the anti-bending ability of the support layer 30.

[0053] Reference Fig.12 As shown, in one embodiment, the width of the two end regions of the opening 33 can be made greater than the width of the middle region of the opening 33. In this way, the edge of the opening 33 in the length direction will form a concave shape, which can reduce the stress concentration of the first edge 31 of the support layer 30 during the bending process, and better improve the bending reliability of the support layer 30.

[0054] Reference Fig.13 As shown, in an optional implementation, the embodiment of the present application further provides a display panel, which includes a first bending area A11, a second bending area A12 and a third bending area A13.

[0055] Specifically, the display panel is a water drop-shaped bent display panel, that is, after the display panel is bent, its bent portion presents a water drop shape. The display panel has a first bending area A11, a second bending area A12 and a third bending area A13, wherein the second bending area A12 and the third bending area A13 are respectively located on both sides of the first bending area A11, and both sides of the second bending area A12 and both sides of the third bending area A13 are connected with non-bending areas A2. In other words, the first bending area A11 and the second bending area A12, and the first bending area A11 and the third bending area A13 are connected through the non-bending area A2, and the side of the second bending area A12 away from the first bending area A11, and the side of the third bending area A13A1 away from the first bending area A11 are connected with the non-bending area A2.

[0056] 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 respectively located in each bending area A1 and a plurality of second portions 312 respectively located in each non-bending area A2. 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, the second portion 312, the first portion 311, and the second portion 312 in sequence.

[0057] Furthermore, the spacing between the corresponding first portions 311 of the two first edges 31 is smaller than the spacing 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. Furthermore, the retracted distances of the first edge 31 in the first bending area A11, the second bending area A12, and the third bending area A13 may be equal or unequal.

[0058] This can reduce the width of the support layer 30 in the first bending area A11, the second bending area A12 and the third bending area A13, thereby reducing the edge stress of the support layer 30 during the bending process, reducing the risk of breakage of the first edge 31, and improving the bending reliability of the support layer 30.

[0059] Reference Fig.14 As shown, in one embodiment, in order to better improve the bending reliability of the support layer 30, the support layer 30 is provided with a plurality of openings 33 in the first bending area A11, and the plurality of openings 33 are distributed along the length direction of the bending axis, and the openings 33 penetrate 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 physical 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 the first edge 31 breaking, and improving the bending reliability of the support layer 30.

[0060] Reference Fig.15 and Fig.16 As shown, in one embodiment, the support layer 30 is provided with a plurality of openings 33 in the first bending area A11, the second bending area A12 and the third bending area A13, and the plurality of openings 33 in each bending area A1 are distributed along the length of the corresponding bending axis, the openings 33 penetrate 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 physical width of the support layer 30 in each bending area A1 can be reduced, thereby better improving the bending performance of the support layer 30.

[0061] Meanwhile, in this embodiment, the spacing between the openings 33 in the first bending zone A11 and the spacing between the openings 33 in the second bending zone A12 and the third bending zone A13 can be adjusted according to actual needs.

[0062] For example, refer to Fig.15 As shown, in one implementation of this embodiment, the spacing between two adjacent openings 33 in the first bending area A11 can be the same as the spacing between 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 made in each bending area A1 at the same time, so as to simplify the preparation steps of the support layer 30.

[0063] For example, refer to Fig.16 As shown, in another implementation of this embodiment, the spacing between two adjacent openings 33 in the first bending zone A11 is different from the spacing between two adjacent openings 33 in the second bending zone A12 and the third bending zone A13. Exemplarily, the spacing between two openings 33 in the first bending zone A11 can be smaller than the spacing between two adjacent openings 33 in the second bending zone A12 and the third bending zone A13. In this way, the bending performance of the support layer 30 in each bending zone A1 can be different, so that different bending conditions can be better addressed.

[0064] Reference Fig.17 As shown, in an optional implementation, the embodiment of the present application further provides a display panel, in which the first portion 311 is configured to be arc-shaped, and the notch of the arc-shaped first portion 311 faces the inner side of the support layer 30 .

[0065] Specifically, the notch of a part of the arc is directed toward the supporting layer 30, which can also be understood as the first part 311 being roughly an outwardly convex arc. In this way, setting the first part 311 as an arc convex toward the outside of the supporting 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 supporting layer 30.

[0066] Based on the same inventive concept, an embodiment of the present application discloses a display device, comprising any display panel as described above in the embodiment of the present application.
