[0051] Curved display devices have received widespread attention due to their excellent viewing angles and human visual experience.

[0052] A curved backlight module is provided in the curved display device to provide a light source for the curved display device. The curved backlight module comprises a back panel and a light board, which are connected and fixed to the back panel. A plurality of LED light sources are provided on the light board. Due to the curvature of the back panel, when the light board and the back panel are assembled and fitted, the light board is easily separated from the back panel in the area where the curvature of the back panel is larger, resulting in inconsistent light mixing height of the curved backlight module and uneven light emission of the curved display device.

[0053] In view of this, the embodiments of the present application provide a backlight module and a display device, which can solve the above technical problems.

[0054] Figure 1 is a schematic diagram of the structure of a backlight module 10 provided in an embodiment of the present invention, such as Figure 1 As shown, in an embodiment of the present invention, a backlight module 10 is provided, comprising: a curved back panel 1 and a backlight panel 2, wherein the backlight panel 2 is disposed on one side of the curved back panel 1 and is bonded to the curved back panel 1;

[0055] The backlight panel 2 includes at least two sub-panels, each of which includes a main body and at least one connecting portion disposed on one side of the main body. Adjacent sub-panels are rotatably connected via the connecting portion so that the adjacent sub-panels are bent along the bending direction of the curved back panel 1 .

[0056] A backlight module 10 provided in an embodiment of the present invention includes a curved back panel 1 and a backlight panel 2. The backlight panel 2 is arranged on one side of the curved back panel 1 and is fitted with the curved back panel 1. The backlight panel 2 includes at least two sub-panels. Each sub-panel includes a body and at least one connecting portion. The connecting portion is arranged at the end of the body. Adjacent sub-panels are rotatably connected through the connecting portion, so that the surface formed by splicing at least two sub-panels is bent along the bending direction of the curved back panel 1. That is, the backlight panel 2 includes at least two sub-panels arranged along the bending direction of the curved back panel 1. Among the sub-panels arranged along the bending direction of the curved back panel 1, one of each two adjacent sub-panels can be rotated in a direction close to the other, or one can be rotated in a direction away from the other. That is to say, the angle between each two adjacent sub-lamp panels can be changed, so that the bending degree of the backlight panel 2 is consistent with or similar to the bending degree of the curved back panel 1. At the same time, through the rotational connection between adjacent sub-lamp panels, the stress generated when the backlight panel 2 is bent is released, that is, the phenomenon of stress concentration when the backlight panel 2 is bent is avoided, thereby effectively reducing the probability of separation of the backlight panel 2 and the curved back panel 1, ensuring that the mixing height in the mixing area of ​​the display module is consistent, thereby ensuring uniform light output of the backlight module 10 and uniform light emission of the display device, thereby improving the structural stability and service life of the display device.

[0057] In the embodiment of the present invention, the curved back panel 1 is an arc-shaped structure, and the curved back panel 1 includes a first end and a second end opposite to the first end, and the bending degree of the first end and the second end is smaller than the bending degree of the middle part of the curved back panel 1. The above-mentioned sub-light panels are arranged along the bending direction of the curved back panel, that is, the sub-light panels are arranged along the direction in which the first end of the curved back panel 1 points to the second end or along the direction in which the second end points to the first end. In other words, the curved back panel 1 is arranged along the curved back panel 1. Figure 1The backlight panel 2 is bent in the ab direction as shown, and the backlight panel 2 includes at least two sub-light panels arranged along the bending direction of the curved back panel 1, that is, the backlight panel 2 includes at least two sub-light panels arranged along the ab direction, and adjacent sub-light panels can rotate relative to each other, so that the bending degree of the backlight panel 2 is consistent with or similar to the bending degree of the curved back panel 1. The bending degree of the backlight panel 2 mentioned here is similar to the bending degree of the curved back panel 1, which means that it is within the allowable error range and does not affect the light mixing height of the display module.

[0058] Figure 2 It is a structural schematic diagram of a backlight lamp board 2 including two sub-lamp boards in a backlight module 10 provided in an embodiment of the present invention; Figure 3 This is another structural schematic diagram of a backlight panel 2 in a backlight module 10 provided in an embodiment of the present invention including two sub-panels; Figure 4 It is a schematic structural diagram of a backlight panel 2 in a backlight module 10 provided in an embodiment of the present invention, which includes four sub-panels.

[0059] In the embodiment of the present invention, the number of sub-light panels can be two, three or four, etc. Figures 2 to 3 As shown, the backlight panel 2 includes a first sub-panel 21 and a second sub-panel 22. Figure 2 In the middle, the sub-light board is a rectangular structure. Figure 3 The neutron lamp board is an L-shaped structure. Both of the above structures can reduce stress when the backlight lamp board 2 is bent.

[0060] like Figure 4 As shown, the backlight panel 2 includes a first sub-lamp panel 21, a second sub-lamp panel 22, a third sub-lamp panel 24 and a fourth sub-lamp panel 25. By splicing the four sub-lamp panels to form the backlight panel 2, the stress can be further reduced to prevent the sub-lamp panels from detaching from the curved back panel 1.

[0061] The embodiment of the present invention is now described by taking the first sub-lamp board 21 and the second sub-lamp board 22 as an example.

[0062] Figure 5 is a local enlarged schematic diagram of point A, such as Figure 5 As shown, as a possible implementation, the first sub-lamp board 21 includes a first body 211 and at least one first connecting portion 212 arranged at the end of the first body 211; the second sub-lamp board 22 includes a second body 221 and at least one second connecting portion 222 arranged at the end of the second body 221; the first connecting portion 212 and the second connecting portion 222 are staggered.

[0063] In the first sub-lamp board 21, the end of the first body 211 is provided with a first connection portion 212, and in the second sub-lamp board 22, the end of the second body 221 is provided with a second connection portion 222, and the first connection portion 212 and the second connection portion 222 are matched and connected to realize the connection between the first sub-lamp board 21 and the second sub-lamp board 22. In order to facilitate the connection of the first connection portion 212 and the second connection portion 222, and save the space occupied by the first connection portion 212 and the second connection portion 222, the first connection portion 212 and the second connection portion 222 are staggered, that is, the connection arrangement direction of the first connection portion 212 and the second connection portion 222 is parallel to the extension direction of the first connection portion 212.

[0064] In some embodiments, the first sub-lamp board 21 includes at least two first connection parts 212 , the second sub-lamp board 22 includes at least one second connection part 222 , and one second connection part 222 is inserted between every two adjacent first connection parts 212 .

[0065] If the first sub-lamp board 21 includes two first connecting parts 212, and the second sub-lamp board 22 includes one second connecting part 222, after the first connecting part 212 and the second connecting part 222 are matched, the relative position relationship between the first connecting part 212 and the second connecting part 222 at the matching position is: first connecting part 212-second connecting part 222-first connecting part 212;

[0066] If the first sub-lamp board 21 includes two first connecting parts 212, and the second sub-lamp board 22 includes two second connecting parts 222, after the first connecting part 212 and the second connecting part 222 are matched, the relative position relationship between the first connecting part 212 and the second connecting part 222 at the matching position is: first connecting part 212-second connecting part 222-first connecting part 212-second connecting part 222;

[0067] The above-mentioned first sub-lamp board 21 includes at least two first connecting parts 212, and a gap is formed between each two adjacent first connecting parts 212. When the first sub-lamp board 21 is connected to the second sub-lamp board 22, the second connecting part 222 is set at the gap position and connected to the two adjacent connecting parts. That is to say, a second connecting part 222 is inserted between each two adjacent first connecting parts 212 to ensure the stability of the connection between the first connecting part 212 and the second connecting part 222.

[0068] In addition, a plurality of areas for setting the first connection parts can be preset at the end of the first sub-light panel 21, and at least two first connection parts 212 are set in each area. When the number of the first connection parts 212 in an area is not less than three, the gaps between two adjacent first connection parts 212 are equal to ensure the stability and reliability of the connection between the first connection part 212 and the second connection part 222.

[0069] The outer surfaces of the first connection part 212 and the second connection part 222 are arc surfaces, that is, the surfaces at the matching position of the first connection part 212 and the second sub-lamp panel 22, and the surfaces at the matching position of the second connection part 222 and the first sub-lamp panel 21 are all arc surfaces. When the first sub-lamp panel 21 and the second sub-lamp panel 22 rotate relative to each other, interference between the first connection part 212 and the second connection part 222 can be effectively prevented.

[0070] In addition, when the first connection part 212 and the second connection part 222 are matched, a matching gap is provided between the first connection part 212 and the second connection part 222, between the first connection part 212 and the end of the second body 221, and between the second connection part 222 and the end of the first body 211, so as to prevent interference between the first sub-lamp board 21 and the second sub-lamp board 22 when the first sub-lamp board 21 and the second sub-lamp board 22 rotate relative to each other.

[0071] The first sub-lamp board 21 and the second sub-lamp board 22 are connected through the first connection part 212 and the second connection part 222 to achieve rotational connection. There are three connection modes between the first connection part 212 and the second connection part 222 .

[0072] Figure 6 2 is a structural diagram of a connection method of the first connection part 212 and the second connection part 222 in the backlight module 10 provided in an embodiment of the present invention. Figure 7 yes Figure 6 Schematic diagram of the top view of the structure. Figure 6 to Figure 7 As shown, in some embodiments, the first connection portion 212 is formed with a first through hole, and the second connection portion 222 is formed with a second through hole; the backlight lamp board 2 further includes a connection component 23, and the connection component 23 cooperates with the first through hole and the second through hole to connect the first connection portion 212 and the second connection portion 222. The connection component 23 passes through the first through hole and the second through hole to connect the first connection portion 212 and the second connection portion 222, so that the first sub-lamp board 21 and the second sub-lamp board 22 can be relatively rotated, and the rotation angle that can be achieved is relatively large. At the same time, the first sub-lamp board 21 and the second sub-lamp board 22 are positioned, and the first sub-lamp board 21 and the second sub-lamp board 22 are effectively prevented from being misaligned.

[0073] In the above embodiment, the connecting component 23 may be a connecting pin or a bolt, and the connecting component 23 may pass through the first through hole and the second through hole in sequence to connect the first connecting portion 212 and the second connecting portion 222 .

[0074] When the connecting component 23 adopts a connecting pin, a limiting portion 231 is formed at the first end of the connecting pin, and the diameter of the limiting portion 231 is larger than the diameter of the second end. The second end of the connecting pin passes through the first through hole and the second through hole until the first end abuts against the first connecting portion 212 or the second connecting portion 222, and then the end of the second end is deformed so that the second end abuts against the first connecting portion 212 or the second connecting portion 222. That is to say, the second end of the connecting pin also forms a limiting portion 231, thereby limiting the relative positions of the first connecting portion 212 and the second connecting portion 222 in the extension direction of the first connecting portion 212, that is, avoiding relative displacement of the first connecting portion 212 and the second connecting portion 222 in the extension direction of the first connecting portion 212, resulting in failure of the connection between the first sub-lamp board 21 and the second sub-lamp board 22, thereby improving the stability of the connection between the first sub-lamp board 21 and the second sub-lamp board 22.

[0075] When the connecting component 23 adopts a bolt, the diameter of the nut in the bolt is larger than the diameter of the bolt body. The bolt body extends out after passing through the first through hole and the second through hole until the nut abuts against the first connecting part 212 or the second connecting part 222, and then is connected by the nut and the bolt body to prevent the bolt from being separated from the first through hole and the second through hole. That is, the nut and the nut serve as limiting parts 231 at both ends of the bolt to limit the relative positions of the first connecting part 212 and the second connecting part 222 in the extension direction of the first connecting part 212, that is, relative displacement of the first connecting part 212 and the second connecting part 222 in the extension direction of the first connecting part 212 is avoided, resulting in failure of the connection between the first sub-lamp panel 21 and the second sub-lamp panel 22, thereby improving the stability of the connection between the first sub-lamp panel 21 and the second sub-lamp panel 22.

[0076] Figure 8 2 is a schematic structural diagram of another connection method of the first connection portion 212 and the second connection portion 222 in the backlight module 10 provided in an embodiment of the present invention. Figure 8 As shown, in other embodiments, along the extension direction of the first connecting portion 212, one end of at least one first connecting portion 212 is provided with a first protrusion 212a, and the other end is provided with a first groove 212b; one end of at least one second connecting portion 222 is provided with a second groove 222b for cooperating with the first protrusion 212a, and a second protrusion 222a for cooperating with the first groove 212b.

[0077] In the above embodiment, at the connection position between the first connection part 212 and the second connection part 222, a first protrusion 212a is provided at one end of the first connection part 212, and a first groove 212b is provided at the other end; a second protrusion 222a is provided at one end of the second connection part 222, and a second groove 222b is provided at the other end; when the first connection part 212 and the second connection part 222 cooperate, the first protrusion 212a cooperates with the second groove 222b, and the second protrusion 222a cooperates with the second groove 222b; the first protrusion 212a can rotate around its own axis in the second groove 222b, and the second protrusion 222a can rotate around its own axis in the first groove 212b; the size of the second groove 222b is slightly larger than the size of the first protrusion 212a, and the size of the first groove 212b is slightly larger than the size of the second protrusion 222a, so as to limit the positions of the first protrusion 212a and the second protrusion 222a, and improve the stability of the connection between the first sub-lamp board 21 and the second sub-lamp board 22.

[0078] In the above-mentioned first connecting portion 212, a cut surface can be set at the edge position of the side away from the first protrusion 212a, so that the second protrusion 222a can enter the first groove 212b along the cut surface. Similarly, in the second connecting portion 222, a cut surface can also be set at the edge position of the side away from the second protrusion 222a, so that the first protrusion 212a can enter the second groove 222b along the cut surface, so as to achieve the cooperation between the first connecting portion 212 and the second connecting portion 222.

[0079] In order to further facilitate the connection between the first sub-lamp panel 21 and the second sub-lamp panel 22, the first connecting portion 212 and the second connecting portion 222 are elastic. When the first connecting portion 212 and the second connecting portion 222 are matched, the first connecting portion 212 and the second connecting portion 222 may undergo slight elastic deformation to enable the first protrusion 212a and the second groove 222b to match, and the second protrusion 222a and the first groove 212b to match.

[0080] In addition, as a possible implementation method, the first protrusion 212a and the second protrusion 222a can also be made of elastic material, or the first protrusion 212a is elastically connected to the first connecting part 212, and the second protrusion 222a is elastically connected to the second connecting part 222, both of which can achieve the coordination between the first sub-lamp panel 21 and the second sub-lamp panel 22.

[0081] In another embodiment, the first connecting portion 212 is formed with a through hole, and the second connecting portion 222 is a connecting axis. When the first connecting portion 212 and the second connecting portion 222 are connected, the second connecting portion 222 is inserted into the first connecting portion 212 and cooperates with the first connecting portion 212, thereby also realizing the rotational connection between the first sub-lamp panel 21 and the second sub-lamp panel 22.

[0082] In the above embodiment, the first connection portion 212 and the first body 211 are an integrated structure, and the second connection portion 222 and the second body 221 are an integrated structure.

[0083] The structures of the first sub-lamp board 21 and the second sub-lamp board 22 are not limited to the above structures.
