[0047] The features and exemplary embodiments of various aspects of this application will now be described in detail. Numerous specific details are set forth in the following detailed description in order to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this application by illustrating examples thereof.

[0048] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0049] With the development of display technology, users have increasingly higher requirements for the display area of ​​display devices. In use, the larger the display area, the better. Foldable and sliding screens can only increase the screen area by about 50%-60% when unfolded. To further increase the display area, rollable terminals have been developed. The inventors discovered that in rollable terminals, the flexible display panel is prone to warping after unfolding, resulting in poor flatness and affecting the user experience. Based on research into these problems, the inventors provide a flexible display device and mobile terminal to improve the flatness of the flexible display panel after unfolding.

[0050] To better understand this application, the following will be combined with... Figures 1 to 12 The flexible display device and mobile terminal according to embodiments of this application will be described in detail.

[0051] Please see Figure 1 and Figure 2This application provides a winding assembly 1, including a roller 11, a mounting member 12, and a support member 13. The roller 11 is used to fix a first end of a flexible display panel 10 and to wind up the flexible display panel 10. The mounting member 12 is used to fix a second end of the flexible display panel 10. The support member 13 has a storage station and an unfolding station. When the flexible display panel 10 is in the unfolded state, the support member 13 is in the unfolding station. The support member 13 is located on the side of the flexible display panel 10 away from the display surface and is used to provide support for the flexible display panel 10. When the flexible display panel 10 is in the stored state, the support member 13 is in the storage station.

[0052] The roll-up assembly 1 provided in this application includes a roller 11, a mounting member 12, and a support member 13. During use, the first end 101 of the flexible display panel 10 is fixed to the roller 11, and the second end 102 is fixed to the mounting member 12. When the flexible display panel 10 is wound around the roller 11, the flexible display panel 10 is in a retracted state, and the support member 13 is in a retracted position. When the flexible display panel 10 is in an unfolded state, the support member 13 is in an unfolded position. The support member 13 is provided on the side of the flexible display panel 10 away from the light-emitting surface, so that the support member 13 on the side of the flexible display panel 10 away from the light-emitting surface provides support for the flexible display panel 10, thereby improving the flatness of the flexible display panel 10 when it is in the unfolded state and enhancing the user experience.

[0053] In one feasible implementation, the curling component 1 is a unidirectional curling component, that is, only the first end 101 of the flexible display panel 10 is a curling end fixed to the scroll 11, the flexible display panel 10 can be wound around the scroll 11, the second end 102 of the flexible display panel 10 is a stretchable end, and pulling the stretchable end can make the flexible display panel 10 be in an unfolded state, and the mounting component 12 includes a clamping component 122 for clamping the second end 102.

[0054] In the above embodiments, when the distance between the mounting member 12 and the scroll 11 increases, the flexible display panel 10 gradually unfolds, thereby gradually increasing the visible display area of ​​the flexible display panel 10. When the distance between the mounting member 12 and the scroll 11 decreases, the flexible display panel 10 gradually winds around the scroll 11 to a stored state, thereby gradually decreasing the visible display area of ​​the flexible display panel 10 and improving portability.

[0055] In one feasible implementation, such as Figure 3 As shown, the curling component 1 is a bidirectional curling component, and the first end 101 and the second end 102 of the flexible display panel 10 are both curled ends. The mounting component 12 includes a winding shaft 120, and a portion of the flexible display panel 10 is wound around the winding shaft 120.

[0056] In the above embodiment, the portion of the flexible display panel 10 near the first end 101 can be wound onto the scroll 11, and the portion near the second end 102 can be wound onto the winding shaft 120. This allows the flexible display panel 10 to be partially wound onto the scroll 11 and partially wound onto the winding shaft 120 when in a stowed state. As the distance between the winding shaft 120 and the scroll 11 increases, the flexible display panel 10 gradually unfolds, thereby gradually increasing its visible display area. Conversely, as the distance between the winding shaft 120 and the scroll 11 decreases, the flexible display panel 10 gradually winds onto the scroll 11 and partially onto the winding shaft 120 until it reaches a stowed state, thereby gradually decreasing its visible display area and improving portability.

[0057] In one feasible implementation, the flexible display panel 10 is gradually wound around the scroll 11 and / or the winding shaft 120 in the following manner:

[0058] Manually rotate the spool 11 and / or the winding shaft 120 so that the flexible display panel 10 is gradually wound around the spool 11 and / or the winding shaft 120.

[0059] Alternatively, the winding assembly 1 may also include a driving device (not shown in the figure), which is connected to the roller 11 and / or the winding shaft 120 and is used to drive the roller 11 and / or the winding shaft 120 to rotate so that the flexible display panel 10 is gradually wound around the roller 11 and / or the winding shaft 120. The driving device may include a motor, etc., and this application does not make any particular limitation.

[0060] Or, such as Figure 4 As shown, the winding assembly 1 also includes a coil spring 16, which is disposed on the side of the flexible display panel 10 away from the light-emitting surface. The coil spring 16 is fixedly connected to the flexible display panel 10. The coil spring 16 includes a coiled end and a free end. When the winding assembly 1 is a unidirectional winding display device, the winding assembly 1 may include a coil spring 16. The coiled end of the coil spring 16 is located on the side near the first end 101 of the flexible display panel 10, and the free end is located on the 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, so that the coil spring 16 is in an unfolded state. When the stretching of the second end 102 of the flexible display panel 10 is stopped, the coil spring 16 returns to its natural state, that is, the coil spring 16 is wound around the scroll 11 in a coiled state, thereby allowing the flexible display panel 10 to return from the unfolded state to the retracted state. The coil spring 16 is attached to the side of the flexible display panel 10 away from the light-emitting surface, which serves to shrink and expand the screen and support the screen.

[0061] like Figure 5As shown, when the coiling assembly 1 is a bidirectional coiling assembly, the coiling 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 are arranged in a direction parallel to the direction from the coil shaft 11 to the mounting member 12, wherein the direction from the coil shaft 11 to the mounting member 12 is the second direction X. The coiled end of the first coil spring 161 is located on the side close to the first end 101 of the flexible display panel 10. The free end of the first coil spring 161 is fixed to the free end of the second coil spring 162. The coiled end of the second coil spring 162 is located on the side close to the second end 102 of the flexible display panel 10. When the distance between the scroll 11 and the winding shaft 120 increases, it overcomes the contraction force of the first coil spring 161 and the second coil spring 162, and both the first coil spring 161 and the second coil spring 162 are in an unfolded state. When the distance between the scroll 11 and the winding shaft 120 decreases, the first coil spring 161 and the second coil spring 162 gradually return to their natural state, that is, the first coil spring 161 is wound around the scroll 11 in a coiled state, and the second coil spring 162 is wound around the winding shaft 120 in a coiled state, thereby allowing the flexible display panel 10 to return from the unfolded state to the retracted state. Among them, the coil spring 16 can provide auxiliary support for the flexible display panel 10, making the flexible display panel 10 more flat after unfolding.

[0062] It is understood that the ways in which the flexible display panel 10 can be gradually wound around the scroll 11 and / or the scroll 120 are not limited to the above methods, and this application does not make any special limitation.

[0063] In one feasible embodiment, the curling assembly 1 further includes a magnetic suction element 17, which is disposed on the support 13 and / or the coil spring 16 for adsorbing and fixing the support 13 and the coil spring 16.

[0064] In the above embodiment, when the flexible display panel 10 is in the unfolded state, the coil spring 16 is also in the unfolded state synchronously with the flexible display panel 10. The support member 13 is in the unfolded position and contacts the coil spring 16 to provide support for the flexible display panel 10. By providing a magnetic suction member 17 on the coil spring 16 and / or the support member 13, the flexible display panel 10 is attracted and fixed by the magnetic attraction between the coil spring 16 and the support member 13 when it is in the unfolded state. This makes the coil spring 16 and the support member 13 adhere more tightly, thereby making the support member 13 provide better support for the flexible display panel 10 and making the flatness of the flexible display panel 10 higher.

[0065] Specifically, such as Figure 5 As shown, the magnetic attractor 17 may include magnetic powder. When both the coil spring 16 and the support member 13 are made of magnetic materials that can be attracted by the magnetic attractor 17, magnetic powder can be provided in the coil spring 16 and the support member 13 to attract and fix the coil spring 16 and the support member 13.

[0066] The magnetic attractor 17 may also include an electromagnet disposed on the support 13. When the electromagnet is energized, it becomes magnetic and can attract the coil spring 16 to improve the flatness of the flexible display panel 10 when it is in the unfolded state. At the same time, it can also prevent the coil spring 16 from rebounding after the flexible display panel 10 is in the unfolded state, thus maintaining the size of the visible display area of ​​the flexible display panel 10. When the electromagnet is de-energized, its magnetism disappears, and the attraction force on the coil spring 16 disappears, so as to avoid creating resistance when it needs to be stored, which would be detrimental to the winding of the flexible display panel 10.

[0067] In one feasible implementation, such as Figure 5 As shown, the support member 13 includes a first support member 131, which includes multiple support plates. When the first support member 131 is in the unfolding position, the multiple support plates are arranged sequentially in a direction parallel to the direction from the roll 11 to the mounting member 12, that is, the multiple support plates are arranged sequentially in a direction parallel to the second direction X, and adjacent support plates can be flipped and connected by a rotating member 133.

[0068] In the above embodiment, when the first support member 13 is in the unfolding position, the surfaces of the multiple support plates facing the flexible display panel 10 are all located on the same plane to improve the flatness of the flexible display panel 10. The number of support plates is at least two.

[0069] In the above embodiments, the rotating member 133 can be a flexible connecting piece or the like, and this application does not make any special limitation.

[0070] In one feasible implementation, when the first support member 13 is in the storage position, at least some of the support plates are arranged (i.e., stacked) along the first direction Z, wherein the first direction Z is perpendicular to the direction X from the scroll 11 to the mounting member 12. The first direction Z may be perpendicular to the second direction X. Arranging some or all of the support plates along the first direction Z can reduce the volume after storage. The first direction Z may be perpendicular to the display surface of the flexible display panel when it is in the unfolded state.

[0071] In one feasible implementation, such as Figure 5 As shown, the first support member 131 is connected to one of the reel 11 and the mounting member 12. At this time, the first support member 131 includes a free end A that is not connected to the reel 11 or the mounting member 12, and the first support member 131 can be placed in the unfolding position by pulling the free end A.

[0072] In another feasible implementation, the first support member 131 is connected at both ends of the first support member 131 along its unfolding direction (parallel to the second direction X) to one of the scroll 11 and the mounting member 12 and the other, respectively.

[0073] When the first support member 131 is in the unfolding position, except for the support plates at both ends, the two ends of the other support plates opposite each other along the second direction X are respectively connected to the adjacent support plates on both sides. One end of the two ends of the support plate at the end that are opposite each other along the second direction X is connected to the adjacent support plate, and the other end is connected to the roll 11 or the mounting member 12.

[0074] The connection between one end of the first support member 131 along its unfolding direction (parallel to the second direction X) and one of the roller 11 and the mounting member 12 can be a fixed connection, a flip connection, and / or a sliding connection along the first direction Z. The flip connection can be a rotatable connection. Similarly, the connection between the other end of the first support member 131 along its unfolding direction (parallel to the second direction X) and the other of the roller 11 and the mounting member 12 can be a fixed connection, a flip connection, and / or a sliding connection along the first direction Z.

[0075] Optionally, one end of the first support member 131 along its unfolding direction can be slidably connected to one of the scroll 11 or the mounting member 12, while simultaneously achieving a flip-connection along the first direction Z, i.e., a sliding-rotating connection, to ensure smooth unfolding and storage. Alternatively, the other end of the first support member 131 along its unfolding direction can be slidably connected to the other of the scroll 11 or the mounting member 12, while simultaneously achieving a flip-connection along the first direction Z, i.e., a sliding-rotating connection, to ensure smooth unfolding and storage.

[0076] Optionally, one end of the first support member 131 along its unfolding direction is rotatably connected to one of the scroll 11 and the mounting member 12, and / or slidably connected along the first direction Z. Optionally, the other end of the first support member 131 along its unfolding direction is rotatably connected to the other of the scroll 11 and the mounting member 12, and / or slidably connected along the first direction Z.

[0077] In another feasible embodiment, the two ends of the first support member 131 along its unfolding direction are respectively rotatably connected to one of the scroll 11 and the mounting member 12 and the other.

[0078] In another feasible embodiment, one end of the first support member 131 along its unfolding direction is fixedly connected, flipped, slidably connected, or slidably rotated connected to one of the scroll 11 and the mounting member 12. The other end of the first support member 131 along its unfolding direction is slidably connected or slidably rotated connected to the other of the scroll 11 and the mounting member 12 along the first direction Z.

[0079] Optionally, one end of the first support member 131 along its unfolding direction is rotatably connected to the first end of the first connector, and the second end of the first connector is slidably connected to one of the reel or the mounting member along the first direction Z; the other end of the first support member along its unfolding direction is rotatably connected to the first end of the second connector, and the second end of the second connector is slidably connected to the other of the reel or the mounting member along the first direction Z.

[0080] Specifically, the above implementation methods include the following five schemes:

[0081] Option 1: As Figure 6 and Figure 7 As shown, one end of the first support member 131 along its unfolding direction (parallel to the second direction X) is rotatably connected to the scroll 11, and the other end is slidably connected to the mounting member 12 along the first direction Z.

[0082] In the above embodiment, a groove 121 extending along the first direction Z is formed on the mounting member 12. A slider (not shown in the figure) is disposed within the groove 121 for engaging with the groove 121. The slider is slidably disposed within the groove 121 along the first direction Z to achieve a sliding connection. The slider is rotatable within the groove 121 to achieve both a sliding connection and a rotational connection. One end of the first support member 131 along its unfolding direction is rotatably connected to the scroll 11, and the other end is fixedly connected to the slider (the slider may be a protrusion disposed at the other end of the first support member 131). Figure 7 As shown, when the first support member 131 is in the storage position, multiple support plates in the first support member 131 are stacked along the first direction Z. Among them, along the first direction Z, the support plate connected to the scroll 11 is located on the side closer to the second end 102 of the flexible display panel 10, and the other support plates are stacked sequentially on the side of the support plate away from the second end 102 of the flexible display panel 10. When the flexible display panel 10 changes from the storage state to the unfolded state, the first support member 131 simultaneously changes from the storage position to the unfolded position, and the multiple stacked support plates unfold sequentially. The support part of the multiple support plates that is farthest from the support plate connected to the scroll 11 is fixed to the slider. During the unfolding process, this support plate slides towards the flexible display panel 10 so that the surface of the first support member 131 near the flexible display panel 10 is parallel to the light-emitting surface, thereby providing support for the flexible display panel 10.

[0083] In the above embodiment, optionally, the end of the first support member 131 that is slidably connected to the scroll 11 or the mounting member 12 is provided with a protrusion (equivalent to the function of a slider). The protrusion can slide and rotate within a groove extending along the first direction Z on the scroll 11 or the mounting member 12, so as to realize a slidable and rotatable connection between the first support member 131 and the scroll 11 or the mounting member 12, thereby making the unfolding and storage process of the first support member 131 smoother. The shape and gap of the groove and the protrusion can be set as needed to ensure the smoothness of sliding and rotation.

[0084] In the above embodiment, optionally, the end of the first support member 131 that is slidably connected to the scroll 11 or the mounting member 12 is provided with a groove (i.e., a sliding groove), and a protrusion (i.e., a slider, which can serve as a slide rail) extending along the first direction Z is provided on the scroll 11 or the mounting member 12. The protrusion can be installed in the groove, and the groove can slide and rotate along the protrusion to achieve a slidable and rotatable connection between the first support member 131 and the scroll 11 or the mounting member 12, thereby making the unfolding and retraction process of the first support member 131 smoother. The shape and gap of the groove and the protrusion can be set as needed to ensure the smoothness of sliding and rotation.

[0085] Please refer to the above implementation methods as well. Figures 5 to 7 The reel 11 may also include a housing 111, which includes an opening 1111 for the flexible display panel 10 to pass through. A first support member 131 may be attached to the housing 111.

[0086] In the above embodiments, the housing 111 may further include a protruding end 1112, the protruding end 1112 including a first surface 1113, the first surface 1113 for providing support for the flexible display panel 10, and a first support member 131 connected to the end of the protruding end 1112 near the mounting member 12. Figure 7 As shown, when the first support member 131 is in the storage position, multiple support plates are stacked along the first direction Z and can be stored on the side of the protruding end 1112 away from the first surface. The dimensions of the multiple support plates along the second direction X can be equal or unequal. The number of support plates in the first support member 131 can be even.

[0087] In the above embodiment, the minimum distance between the housing 111 and the mounting member 12 is slightly greater than the width of the support plate in the direction from the housing 111 to the mounting member 12, so that when the flexible display panel 10 is in the storage state, the roll-up assembly 1 is more compact and more portable.

[0088] Option 2: One end of the first support member 131 along its unfolding direction (parallel to the second direction X) is fixedly connected to the mounting member 12, and the other end is slidably connected to the scroll 11 along the first direction Z.

[0089] Optionally, one end of the first support member 131 along its unfolding direction is fixedly connected to one of the scroll 11 and the mounting member 12. The other end of the first support member 131 along its unfolding direction is slidably connected to the other of the scroll 11 and the mounting member 12 along the first direction Z. When the first support member 131 is in the unfolded state, multiple support plates are arranged along the second direction X. One of the support plates at both ends is fixedly connected to one of the scroll 11 and the mounting member 12, which is equivalent to using the protruding end 1112 as one of the support plates of the first support member 131; the other of the support plates at both ends is slidably connected to the other of the scroll 11 and the mounting member 12. This scheme is similar to Scheme 1, and will not be described in detail here. The number of support plates in the first support member 131 can be an odd number.

[0090] Option 3: As Figure 8 and Figure 9 As shown, the first support member 131 is rotatably connected at both ends along its unfolding direction to one of the scroll 11 and the mounting member 12 and the other, respectively.

[0091] In the above embodiment, when the first support member 131 is in the storage position, multiple support plates in the first support member 131 are stacked. These multiple support plates may include multiple first support plates 1311, multiple second support plates 1312, and a third support plate 1313. The multiple first support plates 1311, multiple second support plates 1312, and a third support plate 1313 are rotatably connected (e.g., via a rotating member 133), and their two ends after rotatable connection are rotatably connected to one of the scroll 11 and the mounting member 12, respectively. The third support plate 1313 can be connected between the multiple sequentially rotatable first support plates 1311 and the multiple sequentially rotatable second support plates 1312. The multiple first support plates 1311 are sequentially rotatable, for example, by means of a rotating member 133; similarly, the multiple second support plates 1312 are sequentially rotatable, for example, by means of a rotating member 133.

[0092] like Figure 8As shown, when the first support member 131 is in the storage position, the first support plate 1311 connected to the scroll 11 and the second support plate 1312 connected to the mounting member 12 are located on the side of the third support plate 1313 closer to the flexible display panel. Multiple first support plates 1311 are arranged along the first direction Z, multiple second support plates 1312 are arranged along the first direction Z, and the first and second support plates 1311 and 1312 are arranged along the second direction X. When the first support member 131 switches from the storage position to the unfolding position, the first support plate 1311, the second support plate 1312, and the third support plate 1313 are unfolded from their stacked state to provide support for the flexible display panel 10. Figure 9 As shown, the third support plate 1313 is located between the first support plate 1311 and the second support plate 1312, and a plurality of first support plates 1311, a plurality of second support plates 1312 and a third support plate 1313 are arranged along the second direction X.

[0093] In the above embodiments, the scroll 11 may further include a housing 111, the housing including an opening 1111 for the flexible display panel 10 to pass through.

[0094] In the above embodiments, the housing 111 may further include an extension end 1112, the extension end 1112 including a first surface 1113, the first surface 1113 being used to provide support for the flexible display panel 10, and a first support plate 1311 located at the end of the first support member 131 being rotatably connected to the end of the extension end 1112 near the mounting member 12. When multiple first support plates 1311 are stacked, they can be stored in the side of the extension end 1112 away from the first surface 1113. The mounting member 12 includes an extension portion 123, the extension portion 123 including a second surface 1211, the second surface 1211 being used to provide support for the flexible display panel 10, and a second support plate 1312 located at the end of the first support member 131 being rotatably connected to the end of the extension portion 123 near the scroll 11. When multiple second support plates 1312 are stacked, they can be stored in the side of the extension portion 123 away from the second surface 1211.

[0095] Optionally, the width of the third support plate 1313 along the second direction X is greater than or equal to the sum of the width of the first support plate 1311 connected to the third support plate 1313 along the second direction X and the width of the second support plate 1312 connected to the third support plate 1313 along the second direction X. A preset distance D1 is maintained between the protruding end 1112 and the protruding portion 123 to prevent interference between the first support plate 1311 and the second support plate 1312. The width of the third support plate 1313 along the second direction X can be equal to the sum of the preset distance D1, the width of the first support plate 1311 along the second direction X, and the width of the second support plate 1312 along the second direction X. The widths of the multiple first support plates 1311 along the second direction X can be equal or unequal. The widths of the multiple second support plates 1312 along the second direction X can be equal or unequal. The widths of the first support plate 1311 and the second support plate 1312 along the second direction X can be equal or unequal. Optionally, the first support plate 1311 and the second support plate 1312 have the same thickness in the first direction Z. Optionally, the number of the first support plate 1311 and the second support plate 1312 is the same. The number of the first support plate 1311 can be odd, and the number of the second support plate 1312 can be odd.

[0096] In the above embodiment, the minimum distance between the housing 111 and the mounting member 12 is slightly greater than the width of the third support plate 1313 along the second direction X, so as to facilitate the first support member 131 to switch between the unfolding station and the storage station.

[0097] Option 4: The two ends of the first support member 131 along its unfolding direction are respectively fixedly connected to one of the scroll 11 and the mounting member 12. For example, the first support plate 1311 located at the end of the first support member 131 can be fixed to the housing 111. The first support plate 1311 located at the end of the first support member 131 and the housing 111 can be integrally formed or detachably connected. For example, the protruding end 1112 can be used as the first support plate 1311 located at the end of the first support member 131. For example, the second support plate 1312 located at the end of the first support member 131 can be fixed to the mounting member 12. The second support plate 1312 located at the end of the first support member 131 and the mounting member 12 can be integrally formed or detachably connected. For example, the protruding part 123 can be used as the second support plate 1312 located at the end of the first support member 131. The number of first support plates 1311 and the number of second support plates 1312 can be even.

[0098] Option 5: Figure 10 As shown, the first support member 131 is slidably connected at both ends along its unfolding direction to one of the scroll 11 and the mounting member 12, and the other in the first direction Z.

[0099] In the above embodiment, when the first support member 131 is in the storage position, multiple support plates in the first support member 131 are stacked. These multiple support plates may include multiple first support plates 1311, multiple second support plates 1312, and a third support plate 1313. The multiple first support plates 1311, multiple second support plates 1312, and a third support plate 1313 are rotatably connected (e.g., via a rotating member 133), and their two ends after rotatable connection are slidably connected to one of the scroll 11 and the mounting member 12, and the other of the first support plate 1311 and the second support plates 1312, respectively. The multiple first support plates 1311 are rotatably connected sequentially via the rotating member 133, and the multiple second support plates 1312 are rotatably connected sequentially via the rotating member 133.

[0100] Optionally, the two ends of the first support member 131 along its unfolding direction are respectively connected to one of the scroll 11 and the mounting member 12 and the other in the first direction Z, thereby improving the smoothness of the unfolding of the first support member 131.

[0101] Specifically, among the plurality of first support plates 1311, the end of the first support plate 1311 furthest from the third support plate 1313 that is furthest from the second support plate 1312 is rotatably connected to one end of the first connecting member, and the other end of the first connecting member is slidably connected to the scroll 11. Among the plurality of second support plates 1312, the end of the second support plate 1312 furthest from the third support plate 1313 that is furthest from the first support plate 1311 is rotatably connected to one end of the second connecting member, and the other end of the second connecting member is slidably connected to the mounting member 12. The addition of the aforementioned first and second connecting members improves the smoothness of the unfolding of the first support member 131.

[0102] like Figure 10As shown, when the first support member 131 is in the storage position, the first support plate 1311 slidably connected to the scroll 11 and the second support plate 1312 slidably connected to the mounting member 12 are both located on the side of the third support plate 1313 away from the flexible display panel. Among them, multiple first support plates 1311 are arranged along the first direction Z, multiple second support plates 1312 are arranged along the first direction Z, and the first support plate 1311 and the second support plate 1312 are arranged along the second direction X. The third support plate 1313 can be fixedly connected to the flexible display panel 10 or the coil spring 16. When the first support member 131 switches from the storage station to the unfolding station, the first support plate 1311, the second support plate 1312, and the third support plate 1313 are flipped and unfolded from the stacked state. The first support plate 1311, which is slidably connected to the roller 11, and the second support plate 1312, which is slidably connected to the mounting member 12, both slide upward to be flush with the third support plate 1313 to provide support for the flexible display panel 10. The third support plate 1313 is located between the first support plate 1311 and the second support plate 1312. Multiple first support plates 1311, multiple second support plates 1312, and one third support plate 1313 are arranged along the second direction X.

[0103] Optionally, the width of the third support plate 1313 along the second direction X is greater than or equal to the sum of the widths of the first support plate 1311 connected to the third support plate 1313 along the second direction X and the widths of the second support plate 1312 connected to the third support plate 1313 along the second direction X. In the above embodiment, the first support plate 1311 and the second support plate 1312 stacked together are spaced apart by a certain distance D2. The width of the third support plate 1313 along the second direction X can be equal to the sum of the distance D2, the width of the first support plate 1311 along the second direction X, and the width of the second support plate 1312 along the second direction X. The number of first support plates 1311 and second support plates 1312 can be the same. The thickness of the first support plates 1311 and second support plates 1312 in the first direction Z can be the same. The number of first support plates 1311 and the number of second support plates 1312 can be even.

[0104] In the above embodiment, the minimum distance between the housing 111 and the mounting member 12 is slightly greater than the width of the third support plate 1313 along the second direction X, so as to facilitate the first support member 131 to switch between the unfolding station and the storage station.

[0105] In the above embodiments, when the end of the first support member 131 along its unfolding direction is slidably connected to the scroll 11 or the mounting member 12 along the first direction Z perpendicular to the display surface, a groove 121 (equivalent to a slide rail) extending along the first direction Z can be provided on the scroll 11 or the mounting member 12, and a slider is fixedly or rotatably connected to the end of the first support member 131, and the slider can be slidably disposed in the groove 121; or, a groove can be provided at the end of the first support member 131, and a slider (equivalent to a slide rail) extending along the first direction Z can be provided on the scroll 11 or the mounting member 12, and the groove can be slidably disposed in the slider.

[0106] To ensure the flexible display panel 10 remains in its unfolded state, cooperating fixing devices can be provided on the support plate and the coil spring 16. Specifically, a hook-like object can be provided on one of the support plate and the coil spring 16, and a ring-like object can be provided on the other to engage with the hook-like object, thereby maintaining the relative position of the support member 13 and the coil spring 16. When the winding assembly 1 is a unidirectional winding assembly, the hook-like object or ring-like object on the support member 13 is located at the end of the support member 13 closest to the mounting member 12 when the support member 13 is in the unfolded position. When the winding assembly 1 is a bidirectional winding assembly, the hook-like object or ring-like object on the support member 13 is located at the two opposite ends along the second direction X when the support member 13 is in the unfolded position. By providing the hook-like object or ring-like object, the spring-like assembly 1 is prevented from springing back after unfolding.

[0107] In another feasible implementation, such as Figure 11 As shown, the support member 13 includes a second support member 132. One end of the second support member 132 is connected to the roller 11, and the other end of the second support member 132 is connected to the mounting member 12. The second support member 132 is telescopic along the second direction X.

[0108] In the above embodiment, the second support member 132 is a self-stretching elastic member. When the distance between the scroll 11 and the mounting member 12 increases to make the flexible display panel 10 unfolded, the second support member 132 is stretched to be in the unfolded position; when the distance between the scroll 11 and the mounting member 12 decreases to make the flexible display panel 10 retracted, the second support member 132 retracts (resets) to be in the retracted position.

[0109] Specifically, the second support member 132 includes an elastic support mesh. Specifically, the elastic support mesh is an elastic support mesh structure including a plurality of springs arranged along a third direction. The springs can extend along a second direction X. The third direction can be perpendicular to the second direction X. The third direction can be perpendicular to the first direction Z.

[0110] In one feasible implementation, such as Figure 12As shown, the curling assembly 1 also includes a retractable connector 14. The retractable connector 14 is disposed on the side of the support member 13 away from the flexible display panel 10. One end of the retractable connector 14 is connected to the roller 11 and the other end is connected to the mounting member 12. The retractable connector 14 can extend and retract along the second direction X.

[0111] The retractable connector 14 extends and retracts along the second direction X of the roll to increase or decrease the distance between the roll 11 and the mounting member 12, thereby causing the first support member 131 to unfold or retract.

[0112] In one feasible implementation, such as Figure 12 As shown, the curling assembly 1 also includes a drive member 15. The drive member 15 is connected to the retractable connector 14 and is used to drive the retractable connector 14 to extend or retract along the second direction X.

[0113] The retractable connector 14 can be a structure that provides support along the second direction X, so that when the support member 13 is an elastic support net, the flexible display panel 10 is kept in an unfolded state, and the flexible display panel 10 is prevented from returning to a retracted state due to the elastic rebound of the elastic support net itself.

[0114] Specifically, the side surface of the elastic support mesh facing away from the flexible display panel 10 can be connected to the telescopic connector 14 through the support connector. On the one hand, this can further enhance the support for the middle position of the flexible display panel 10 and improve the flatness of the flexible display panel 10. On the other hand, it can make the telescopic movement of the telescopic connector 14 more stable.

[0115] In the above embodiments, the retractable connector 14 and the drive component 15 can automate the curling assembly 1, that is, the flexible display panel 10 can automatically switch between the retracted state and the unfolded state, thereby further improving the user experience.

[0116] In one feasible implementation, such as Figures 13 to 16As shown, the retractable connector 14 includes a first connecting portion 141, a second connecting portion 142, a rotating portion 143, a first connecting rod 144, and a second connecting rod 145. The rotating portion 143 includes a first end and a second end. The first end is rotatably connected to one end of the first connecting rod 144, and the other end of the first connecting rod 144 is rotatably connected to the middle portion of the first connecting portion 141. The second end is rotatably connected to one end of the second connecting rod 145, and the other end of the second connecting rod 145 is rotatably connected to the middle portion of the second connecting portion 142. The first connecting portion 141 is used to connect to one of the reel 11 and the mounting member 12, and the second connecting portion 142 is used to connect to the other of the reel 11 and the mounting member 12. A driving member 15 is connected to the middle portion of the rotating portion 143 and is used to drive the rotating portion 143 to rotate to adjust the distance between the first connecting portion 141 and the second connecting portion 142.

[0117] In the above embodiment, the retractable connector 14 includes a first connecting portion 141, a second connecting portion 142, a rotating portion 143, a first connecting rod 144, and a second connecting rod 145. A driving member 15 is connected to the middle of the rotating portion 143. The driving member 15 drives the rotating portion 143 to rotate, increasing the distance between the first connecting rod 144 and the second connecting rod 145 in a direction parallel to the first connecting portion 141 pointing towards the second connecting portion 142 (which may be parallel to the second direction X). This also increases the angle between the rotating portion 143 and the first and second connecting rods 144 and 145, providing a force away from the first connecting portion 141 and the second connecting portion 142, thereby increasing the distance between them and allowing the flexible display panel 10 to unfold. Simultaneously, the driving member 15 can drive the rotating portion 143 to rotate, reducing the distance between the first connecting portion 141 and the second connecting portion 142, thus allowing the flexible display panel 10 to be stored. The retractable connector 14 has a simple structure and low cost.

[0118] In one feasible implementation, such as Figure 13 and Figure 14 As shown, the drive unit 15 includes a telescopic part 151 and a first motor connected to the telescopic part 151. One end of the telescopic part 151 is fixed to the middle of the first connecting part 141 and the other end is fixed to the middle of the rotating part 143. The first motor can drive the telescopic part 151 to extend and retract in a direction parallel to the first connecting part 141 and pointing to the second connecting part 142.

[0119] In the above embodiment, when the first motor drives the retractable part 151 to extend, the distance between the center of the first connecting part 141 and the rotating part 143 increases in a direction parallel to the first connecting part 141 pointing to the second connecting part 142, thereby causing the rotating part 143 to rotate. This increases the distance between the first connecting rod 144 and the second connecting rod 145 in a direction parallel to the first connecting part 141 pointing to the second connecting part 142, and increases the angle between the rotating part 143 and the first connecting rod 144 and the second connecting rod 145. This provides a force away from the first connecting part 141 and the second connecting part 142, increasing the distance between them, thereby realizing the unfolding of the flexible display panel 10. At the same time, when the first motor drives the retractable part 151 to retract, it can reduce the distance between the center of the first connecting part 141 and the center of the rotating part 143 along the column direction parallel to the first connecting part 141 and pointing to the second connecting part 142, so that the rotating part 143 rotates, thereby reducing the distance between the first connecting part 141 and the second connecting part 142, and realizing the storage of the flexible display panel 10.

[0120] In the above embodiment, the telescopic part 151 can be a lead screw and a second slider that is threaded with the lead screw. The second slider can be fixed to the middle of the first connecting part 141. The first end 101 of the lead screw is fixed to the middle of the rotating part 143, and the other end is threaded with the second slider. The lead screw can be driven to rotate by the first motor, thereby adjusting the distance between the second slider and the first end 101, so as to adjust the distance between the middle of the first connecting part 141 and the middle of the driving member 15.

[0121] When the winding assembly 1 is a unidirectional winding assembly, the retractable connector 14 can be used to move the mounting member 12 and the scroll 11 closer together or further apart, thereby enabling the flexible display panel 10 to automatically unfold and retract. When the winding assembly 1 is a bidirectional winding assembly, the retractable connector 14 can be used to move the scroll 11 and the winding shaft 120 closer together or further apart, thereby enabling the flexible display panel 10 to slide and unfold bidirectionally.

[0122] In another feasible implementation, such as Figure 15 and Figure 16 As shown, the driving component 15 includes a second motor 152 for driving the rotating part 143 to rotate, and the second motor 152 is connected to the middle of the rotating part 143.

[0123] In the above embodiment, the shaft of the second motor 152 can be connected to the middle of the rotating part 143. The extension direction of the shaft of the second motor 152 is perpendicular to the extension direction of the rotating part 143. That is, the second motor 152 can directly drive the rotating part 143 to rotate, so that the distance between the first connecting rod 144 and the second connecting rod 145 increases or decreases in the direction parallel to the first connecting part 141 and pointing to the second connecting part 142. This increases or decreases the angle between the rotating part 143 and the first connecting rod 144 and the second connecting rod 145, thereby providing the first connecting part 141 and the second connecting part 142 with forces moving away from or closer to each other, increasing or decreasing the distance between the first connecting part 141 and the second connecting part 142, thereby realizing the unfolding or folding of the flexible display panel 10.

[0124] In the above embodiment, the second motor 152 is used to directly drive the rotating part to rotate, which makes the overall structure of the driving component 15 simpler and helps to save on manufacturing process and reduce production costs.

[0125] In one feasible embodiment, the drive member 15 includes a cylinder, the cylinder body being fixed to the middle of one of the first connecting part 141 and the rotating part 143, and the cylinder rod end being fixed to the middle of the other. The rotating part 143 is rotated by the cylinder to realize the extension and retraction of the telescopic connecting member 14.

[0126] Optional, Figures 1 to 12 In the corresponding design, the second end 102 of the flexible display panel 10 is a rollable end or a stretchable end. Optionally, Figures 1 to 11 The corresponding solution can include a retractable connector 14 and a drive component 15.

[0127] like Figure 17 As shown, this application also provides a flexible display device 2, including a flexible display panel 10 and any of the roll-up components 1 provided in the above embodiments.

[0128] The flexible display panel 10 can be an organic light-emitting flexible display panel, etc. The first end of the flexible display panel 10 is fixed to a scroll 11 within the rolling assembly 1, and the flexible display panel 10 is wound around the scroll 11. The second end of the flexible display panel 10 is fixed to a mounting member 12 within the rolling assembly 1. The flexible display panel 10 has a stowed state and a rolled state. The rolling assembly 1 is used to switch the flexible display panel 10 between the stowed state and the unfolded state, thereby achieving a balance between large-area display and portability of the flexible display panel.

[0130] This application also provides a mobile terminal, including any of the flexible display devices provided in the above embodiments.

[0131] This mobile terminal achieves both a large display area and portability. While achieving a large display area, it also ensures a high degree of flatness of the flexible display panel 10, thereby enhancing the visual experience.

These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of this application, thereby enabling those skilled in the art to effectively utilize this application and its modifications. This application is limited only by the claims and their full scope and equivalents.
