The inventor finds that in the curled terminal, the flexible display panel is easy to warp after being unfolded, so that the flatness of the flexible display panel is poor, and the user experience is affected. Based on the study on the above problems, the inventor provides a flexible display device and a mobile terminal to improve the flatness of the flexible display panel after being unfolded.

For a better understanding of the present application, a flexible display device and a mobile terminal according to embodiments of the present application are described in detail below with reference to fig. 1 to 12.

Referring to fig. 1 and 2, the present embodiment provides a crimping assembly 1 comprising a spool 11, a mounting member 12 and a support member 13. The reel 11 is used to fix a first end of the flexible display panel 10 and wind up the flexible display panel 10. The mounting member 12 is used to secure a second end of the flexible display panel 10. The support 13 has a storage station and a deployment station. When the flexible display panel 10 is in the unfolded state, the supporting member 13 is in the unfolded position, the supporting member 13 is disposed on a side of the flexible display panel 10 facing away from the display surface, and the supporting member 13 is used for providing support for the flexible display panel 10. When the flexible display panel 10 is in the storage state, the support 13 is in the storage station.

The crimping assembly 1 provided herein includes a spool 11, a mounting member 12, and a support member 13. In the use, the first end 101 and the spool 11 of flexible display panel 10 are fixed, the second end 102 is fixed in installed part 12, when flexible display panel 10 winds in spool 11, flexible display panel 10 is in the state of accomodating, support piece 13 is in the station of accomodating, and when flexible display panel 10 is in the state of expanding, support piece 13 is in the station of expanding, the one side that flexible display panel 10 deviates from the light-emitting surface is provided with support piece 13, with the support piece 13 of the one side that deviates from the light-emitting surface by flexible display panel 10 provides the support for flexible display panel 10, thereby the roughness when flexible display panel 10 is in the state of expanding has been promoted, user experience has been promoted.

In one possible embodiment, the curling assembly 1 is a unidirectional wound curling assembly, i.e. only the first end 101 of the flexible display panel 10 is a curled end fixed to the reel 11, the flexible display panel 10 may be wound on the reel 11, the second end 102 of the flexible display panel 10 is a stretchable end, pulling the stretchable end may cause the flexible display panel 10 to be in an unfolded state, and the mounting member 12 includes a clamping member 122 for clamping the second end 102.

In the above embodiment, when the distance between the mount 12 and the reel 11 increases, the flexible display panel 10 may be gradually put in the unfolded state, so that the visual display area in the flexible display panel 10 gradually increases. When the distance between the mount 12 and the reel 11 is reduced, the flexible display panel 10 can be gradually wound around the reel 11 to a housed state, so that the visual display area in the flexible display panel 10 is gradually reduced while portability is improved.

In one possible embodiment, as shown in fig. 3, the curl assembly 1 is a curl assembly that is wound in two directions, the first end 101 and the second end 102 of the flexible display panel 10 are both curl ends, the mounting member 12 includes a winding shaft 120, and the flexible display panel 10 is partially wound around the winding shaft 120.

In the above embodiment, the portion of the flexible display panel 10 near the first end 101 may be wound around the winding shaft 11 and the portion near the second end 102 may be wound around the winding shaft 120, so that the portion of the flexible display panel 10 is wound around the winding shaft 120 and the portion of the flexible display panel is wound around the winding shaft 11 when the flexible display panel 10 is in the stored state. When the distance between the winding shaft 120 and the winding shaft 11 increases, the flexible display panel 10 may be gradually put in an unfolded state, so that the visual display area of the flexible display panel 10 gradually increases. When the distance between the winding shaft 120 and the winding shaft 11 is reduced, the flexible display panel 10 may be made to be partially wound around the winding shaft 120 to a housed state gradually, so that the visual display area of the flexible display panel 10 is made to be gradually reduced while portability is improved.

In one possible embodiment, the manner in which the flexible display panel 10 is gradually wound around the reel 11 and/or the winding shaft 120 includes:

the reel 11 and/or the winding shaft 120 is manually rotated such that the flexible display panel 10 is gradually wound around the reel 11 and/or the winding shaft 120.

Alternatively, the curling assembly 1 further includes a driving device (not shown in the drawings), which is connected to the reel 11 and/or the winding shaft 120 and is used to drive the reel 11 and/or the winding shaft 120 to rotate, so that the flexible display panel 10 is gradually wound on the reel 11 and/or the winding shaft 120, and the driving device may include a motor, etc., which is not particularly limited herein.

Alternatively, as shown in fig. 4, the curling assembly 1 further includes a coil spring 16, where the coil spring 16 is disposed on a side of the flexible display panel 10 facing away from the light emitting surface, and the coil spring 16 is fixedly connected to the flexible display panel 10, and the coil spring 16 includes a curled end and a free end, where when the curling assembly 1 is a unidirectional winding display device, the curling assembly 1 may include one coil spring 16, where the curled end of the coil spring 16 is located on a side near the first end 101 of the flexible display panel 10, and the free end is located on a side near the second end 102 of the flexible display panel 10. When the second end 102 of the flexible display panel 10 is stretched, the contraction force of the coil spring 16 is overcome to bring the coil spring 16 into an expanded state, and when the stretching of the second end 102 of the flexible display panel 10 is stopped, the coil spring 16 is restored to a natural state, that is, the coil spring 16 is wound around the reel 11 to be in a curled state, so that the flexible display panel 10 is restored to a housed state from the expanded state. The coil spring 16 is attached to the side of the flexible display panel 10 facing away from the light emitting surface, and serves to retract and expand the screen and support the screen.

As shown in fig. 5, when the curling assembly 1 is a bi-directionally wound curling assembly, the curling assembly 1 may include two coil springs, such as a first coil spring 161 and a second coil spring 162, the first coil spring 161 and the second coil spring 162 being arranged in parallel to a direction from the reel 11 toward the mounting member 12, wherein the direction from the reel 11 toward the mounting member 12 is a second direction X, the curled end of the first coil spring 161 is located at a side near the first end 101 of the flexible display panel 10, the free end of the first coil spring 161 is fixed with the free end of the second coil spring 162, and the curled end of the second coil spring 162 is located at a side near the second end 102 of the flexible display panel 10. When the distance between the spool 11 and the winding shaft 120 increases, the first and second coil springs 161 and 162 are both in an expanded state against the contraction force of the first and second coil springs 161 and 162, and when the distance between the spool 11 and the winding shaft 120 decreases, the first and second coil springs 161 and 162 are both gradually restored to a natural state, that is, the first coil spring 161 is wound around the spool 11 to be in a curled state and the second coil spring 162 is wound around the winding shaft 120 to be in a curled state, so that the flexible display panel 10 is restored to a housed state from the expanded state. The coil springs 16 can serve as auxiliary supports for the flexible display panel 10, so that the flexible display panel 10 is smoother after being unfolded.

It is understood that the manner in which the flexible display panel 10 can be gradually wound around the reel 11 and/or the winding shaft 120 is not limited to the above manner, and the present application is not particularly limited.

In a possible embodiment, the crimping assembly 1 further comprises a magnetic attraction member 17, the magnetic attraction member 17 being provided to the support member 13 and/or the coil spring 16 for attracting and securing the support member 13 and the coil spring 16.

The magnetic attraction member 17 may further include an electromagnet disposed on the support member 13, and when the electromagnet is electrified, the electromagnet has magnetism, and can attract the coil spring 16, so as to promote flatness of the flexible display panel 10 in the unfolded state. While also preventing the spring 16 from springing back after the flexible display panel 10 is in the extended state, maintaining the size of the viewable display area of the flexible display panel 10. When the electromagnet is de-energized, the magnetism disappears, and the attraction force to the coil spring 16 disappears, so that the situation that the flexible display panel 10 is not beneficial to winding due to resistance generated when the flexible display panel needs to be stored is avoided.

In a possible embodiment, as shown in fig. 5, the support 13 comprises a first support 131, the first support 131 comprising a plurality of support plates, which are arranged in succession in a direction parallel to the direction directed by the reel 11 towards the mounting 12 when the first support 131 is in the unwinding station, i.e. in a direction parallel to the second direction X, and between adjacent support plates are connected in turn by means of a rotating member 133.
