Fig. 4 is a schematic view of the sealing member 215 sealing the first mover 211 and the receiver 213, and fig. 5 is a schematic view of the sealing member 215 sealing the second mover 212 and the receiver 213, in fig. 4 and 5, the sealing member 215 may be deformed by the pressing of the first mover 211 and the receiver 213, the second mover 212 and the receiver 213, and the deformed sealing member 215 has a tendency to recover deformation, so that the gaps between the first mover 211 and the receiver 213, and between the second mover 212 and the receiver 213 can be filled in a sealing manner to achieve a sealing effect.
The embodiment of the application provides the sealing component 215, can strengthen the leakproofness between first moving part 211 and holding part 213, and strengthen the leakproofness between second moving part 212 and holding part 213, reduce the possibility that first medium 214 takes place to leak to improve the transmission reliability between first moving part 211 and the second moving part 212, improve the operational reliability of supporting member 21, and then can improve the security and the reliability of display module assembly 100.

The arc end of the driving lever 31 is tangent to the first moving member 211, and there may be various arrangements between the arc end and the first moving member 211.
For example, in the embodiment of the present application, the arc-shaped end may contact the first moving member 211, and when the arc-shaped end approaches the first moving member 211 and applies a force to the first moving member 211, the first moving member 211 compresses the first medium 214 under the pushing of the arc-shaped end, so that the first medium 214 is forced to push the second moving member 212 to be lifted; when the arc end is far away from the first moving member 211, the abutting force of the arc end to the first moving member 211 is gradually reduced until the first moving member 211 is pushed by the first medium 214 to move by the first moving member 211 when the abutting force of the arc end to the first moving member 211 is smaller than the pressure given by the first medium 214, and at the moment, the acting force of the second moving member 212 to the first medium 214 is reduced, and the second moving member 212 is lowered.

It should be noted that, in the embodiment of the present application, the horizontal plane of the second moving member 212 may be higher than the horizontal plane of the first moving member 211, so that the first medium 214 may fall back under the action of its own gravity, so as to simplify the transmission connection manner of the first medium 214 and the second moving member 212, and thus simplify the structural form of the display module 100.
The arc-shaped end is tangent to the first moving part 211, the possibility that the driving rod 31 and the first moving part 211 are blocked when in force transmission can be reduced, and the motion stability of the driving rod 31 and the first moving part 211 is improved, so that the working stability and reliability of the display module 100 are improved. And the end of the driving lever 31 is provided with an arc-shaped end, it is also possible to reduce the friction between the driving lever 31 and the first moving member 211, thereby reducing the friction loss during the power transmission.

The rolling member 33 is rotatably connected to the end of the driving rod 31, and the rolling member 33 may take various forms, for example, it may have a cylindrical structure or a spherical structure, etc. The rolling part 33 is used for being tangent to the first moving part 211, when the rolling part 33 is abutted against the first moving part 211, the rolling part 33 can roll along the surface of the first moving part 211 under the force, so that the friction force between the driving rod 31 and the first moving part 211 can be further reduced, and the friction loss is reduced. And further, the stability and reliability of force transmission can be further improved, which is beneficial to improving the working stability and reliability of the display module 100.
Further, referring to fig. 8 and 9, the driving assembly 30 further includes a support 32, the support 32 is disposed on the fixing frame 11, and the driving rod 31 is connected to the support 32.
The embodiment of the application can be convenient for the connection of the driving rod 31 and the fixing frame 11 by arranging the support 32, and is favorable for reducing the connection difficulty of the driving assembly 30 and the supporting member 21.
With continued reference to fig. 8 and 9, in the display module 100 of any of the above embodiments, the supporting device 1 may further include a connecting assembly 40, the connecting assembly 40 is disposed between two adjacent fixing frames 11 and is rotatably connected to the two fixing frames 11, respectively, and the supporting assembly 20 is located between the connecting assembly 40 and the flexible display panel 2.

The support assembly 20 is located between the connection assembly 40 and the flexible display panel 2, and the support assembly 20 may be mounted on the connection assembly 40, and the support assembly 20 and the connection assembly 40 may be connected in various manners, or may be detachably connected, which is not limited in this application.
Referring to fig. 10, the present application further provides a display device including the display module 100 according to any of the above embodiments. The display device of the application can be a mobile phone, a computer or any other electronic equipment or electronic device with a display function, etc.
The display device of the embodiment of the present application may include a folded state in which the flexible display panel 2 is folded and a flattened state in which the display module 100 is in the second state; in the flattened state, the flexible display panel 2 is flattened and the display module 100 is in the first state.
The following further explains the status switching process of the display module 100 according to the embodiment of the present application:
referring to fig. 2, 3, 8 and 9, when the display module 100 is changed from the first state to the second state, the included angle between the fixing frame 11 and the supporting member 21 is gradually increased, at this time, the driving assembly 30 is driven by the fixing frame 11 to gradually move away from the first moving member 211, the force applied by the driving assembly 30 to the first moving member 211 is gradually reduced, and when the force applied by the driving assembly 30 to the first moving member 211 is smaller than the force applied by the first medium 214 to the first moving member 211, the first moving member 211 moves towards a direction away from the first medium 214, and the first medium 214 is subject to self gravity and flows towards a direction close to the first moving member 211, so that the force applied by the first medium 214 to the second moving member 212 is reduced, and the second moving member 212 starts to descend under the self gravity, thereby gradually separating from the flexible display panel 2. In this process, the flexible display panel 2 may bend by itself, and the bending portion may tilt towards the position close to the second moving member 212, so that a person skilled in the art may reasonably set the displacement of the second moving member 212 during implementation, so as to avoid interference between the second moving member 212 and the tilting portion of the flexible display panel 2 as much as possible.
On the contrary, when the display module 100 is changed from the second state to the first state, the included angle between the fixing frame 11 and the supporting member 21 is gradually reduced, at this time, the driving assembly 30 is driven by the fixing frame 11 to gradually approach the first moving member 211, when the acting force of the driving assembly 30 applied to the first moving member 211 is greater than the acting force of the first medium 214 on the first moving member 211, the first moving member 211 pushes the first medium 214 to flow, so that the first medium 214 gives the second moving member 212 an acting force, forces the second moving member 212 to lift, and then the second moving member 212 gradually approaches the flexible display panel 2, and when the flexible display panel 2 is flat, the second moving member 212 can be abutted against the flexible display panel 2.
