[0036] Next, some embodiments of the present application will be described in detail in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0037] As Figures 1 to 8 shown, according to the first aspect of the present application, the present application provides a display module 100, including a module bottom case 10 and a light board 20 provided with light beads 21. Both the module bottom case 10 and the light board 20 are flexible structures that can be bent. The light board 20 is disposed on the module bottom case 10 so that the display module 100 can form an arc-shaped display screen for cooperating with a box frame 200.

[0038] In an optional embodiment, the module bottom case 10 has a first end face and a second end face, the first end face and the second end face are oppositely arranged, the light board 20 is installed on the first end face, and the second end face is used for connecting with the box frame 200 so that the box frame 200 can control the display module 100 to undergo adaptive deformation and jointly form a corresponding curved screen or straight screen.

[0039] In an optional embodiment, the module bottom case 10 includes a plurality of cases arranged in sequence along a first direction, and at least a limiting component is connected between adjacent two cases. The limiting component is used for limiting the amount of deformation when the module bottom case 10 undergoes bending deformation, avoiding damage to the display module 100 due to excessive deformation amount of the module bottom case 10, and ensuring that the display module 100 can be used normally.

[0040] Exemplarily, the case includes a first case 11 and a second case 12. A part of the structure of the limiting component is formed on the first case 11, and another part of the structure of the limiting component is formed on the second case 12. When the display surface of the display module 100 is concave and the deformation amount reaches the maximum, that is, when the display module 100 is bent into a U-shaped structure, at this time, the limiting component can form a limit for restricting the relative displacement amount between the first case 11 and the second case 12, so that the module bottom case 10 no longer undergoes more deformation, avoiding damage to the display module 100 due to excessive deformation amount of the module bottom case 10, and ensuring that the display module 100 can be used normally.

[0041] Or, when the display surface of the display module 100 is convex and the deformation amount reaches the maximum, that is, when the display module 100 is bent into an N-shaped structure, at this time, the limiting component can form a limit for restricting the relative displacement amount between the first case 11 and the second case 12, so that the module bottom case 10 no longer undergoes more deformation, avoiding damage to the display module 100 due to excessive deformation amount of the module bottom case 10, and ensuring that the display module 100 can be used normally.

[0042] After adopting the above technical solution, since the flexible module bottom shell 10 is prone to damage the display module 100 due to excessive deformation during transportation or assembly. Therefore, in this application, the limiting component restricts the deformation amount of the module bottom shell 10 during bending deformation, thereby avoiding the risk of damage to the display module 100 caused by excessive bending deformation of the module bottom shell 10 during transportation or assembly, so as to ensure that the display module 100 can be used normally.

[0043] In an alternative embodiment, the limiting component includes a first limiting portion 111 and a second limiting portion 121. The first limiting portion 111 is formed on one of the adjacent two shells, and the second limiting portion 121 is formed on the other of the adjacent two shells. The first limiting portion 111 and the second limiting portion 121 cooperate to limit the relative displacement amount between the adjacent two shells, avoid damage to the display module 100 due to excessive deformation of the module bottom shell 10, and ensure that the display module 100 can be used normally.

[0044] In an alternative embodiment, the first limiting portion 111 has a first abutting portion, and the second limiting portion 121 has a second abutting portion. The first abutting portion abuts against the second abutting portion or the end opposite to the second abutting portion when the module bottom shell 10 undergoes bending deformation, so that the module bottom shell 10 no longer undergoes more deformation, thereby avoiding damage to the display module 100 due to excessive deformation of the module bottom shell 10 and ensuring that the display module 100 can be used normally.

[0045] Exemplarily, when the display surface of the display module 100 is concave and the deformation amount reaches the maximum, the first abutting portion abuts against the second abutting portion to form a limit, which is used to limit the relative displacement amount between the first shell 11 and the second shell 12, so that the module bottom shell 10 no longer undergoes more deformation, avoiding damage to the display module 100 due to excessive deformation of the module bottom shell 10 and ensuring that the display module 100 can be used normally.

[0046] Or, when the display surface of the display module 100 is convex and the deformation amount reaches the maximum, the first abutting portion abuts against the end opposite to the second abutting portion, that is, the first abutting portion abuts against the side wall of the second shell 12; the second abutting portion abuts against the end opposite to the first abutting portion, that is, the second abutting portion abuts against the side wall of the first shell 11, which is used to limit the relative displacement amount between the first shell 11 and the second shell 12, so that the module bottom shell 10 no longer undergoes more deformation, avoiding damage to the display module 100 due to excessive deformation of the module bottom shell 10 and ensuring that the display module 100 can be used normally.

[0047] In an alternative embodiment, the first limiting portion 111 has a first connecting portion, and the second limiting portion 121 has a second connecting portion. The first abutting portion is connected to and forms a first limiting groove through the first connecting portion. The second abutting portion is connected to the housing through the second connecting portion and forms a second limiting groove. The first abutting portion moves in the second limiting groove, and the second abutting portion moves in the first limiting groove. When the deformation amount of the display module 100 reaches the maximum, the first abutting portion can form a limit with two opposite end faces of the first limiting groove, and the second abutting portion can form a limit with two opposite end faces of the second limiting groove, so that the module bottom case 10 no longer undergoes more deformation, avoiding damage to the display module 100 due to excessive deformation amount of the module bottom case 10, and ensuring that the display module 100 can be used normally.

[0048] In an alternative embodiment, the first abutting portion is perpendicularly connected to the first connecting portion, that is, the first abutting portion and the first connecting portion form an L-shaped structure.

[0049] In an alternative embodiment, the second abutting portion is perpendicularly connected to the second connecting portion, that is, the second abutting portion and the second connecting portion form an L-shaped structure.

[0050] It should be noted that the structures of the first limiting portion 111 and the second limiting portion 121 can also be other structures, and the main purpose is to limit the relative displacement amount between the first housing 11 and the second housing 12, and the present application does not limit it.
