It should be noted that in the description of the present application, it is to be understood that the terms "central", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner" and "outer" indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be considered as limiting the present application. Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 3, 5 and 7, the second portion 14 is located on the first portion 12, the second portion 14 is also substantially rectangular, and the second portion 14 includes a sliding portion 144 and a second top plate 142. The sliding portions 144 are connected to both sides of the second top plate 142 in the longitudinal direction and are substantially symmetrically disposed. The sliding portion 144 is adapted to cooperate with the sliding slot 124 of the first portion 12 to achieve a sliding connection between the first portion 12 and the second portion 14. The second top plate 142 is disposed opposite to the first top plate 122 and attached to the first top plate. It should be noted that the term "fit" as used herein is to be understood as meaning that the two are in contact without affecting the sliding movement therebetween, or that the gap between the two is within the tolerance of assembly.

It should be noted that in this application, unless explicitly stated or limited otherwise, the first feature "on" or "under" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact with each other through another feature therebetween.

A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

It will be appreciated that in this embodiment, the second portion 14 is slidable relative to the first portion 12 to move away from or towards the first portion 12. In the present embodiment, "the first part 12 and the second part 14 move away from each other" may be understood as that the second part 14 slides relative to the first part 12 and the sliding direction is away from the first part 12. In addition, in the present embodiment, the first portion 12 and the second portion 14 may also move toward each other, and the movement of the two toward each other may be understood as the second portion 14 sliding with respect to the first portion 12 with the sliding direction toward the first portion 12.

It is further noted that, in the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "connected" are to be interpreted broadly, e.g. as a fixed connection, a detachable connection or an integral connection; may be a mechanical connection; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

Referring to fig. 1, 4 and 5, in the present embodiment, when the first portion 12 and the second portion 14 move toward each other to the limit position (i.e., when the first portion 12 and the second portion 14 approach each other until the first portion 12 and the second portion 14 are fit together), the first portion 12 and the second portion 14 are integrally formed into a substantially rectangular housing 10. Referring to fig. 2, 6 and 7, as first portion 12 and second portion 14 move apart (i.e., away from each other), first portion 12 and second portion 14 separate.

Referring to fig. 3, 5 and 7, the reel 20 is rotatably disposed in the first portion 12, and specifically, the reel 20 is rotatably disposed in the accommodating space 120. That is, the spool 20 is mounted to the first portion 12 and is rotatable relative to the first portion 12. The roll 20 is adapted to be connected to a driving mechanism 70 such that the roll 20 can be rotated relative to the first portion 12 to release or roll up the flexible display 30 under the driving of the driving mechanism 70.

It will be appreciated that the rotational positioning of the spool 20 on the first portion 12 may refer to the spool 20 being mounted directly on the first portion 12, or may refer to the spool 20 being mounted on the first portion 12 via other media.

In addition, with continued reference to fig. 5 and 7, one end of the flexible display 30 is fixedly connected to the second portion 14, and the other end is wound on the reel 20. The roll 20 may be used to roll up the flexible display 30 and release the flexible display 30. Wherein upon a movement of the first and

second portions

12, 14 away from each other, the roller 20 is able to rotate to release the flexible display 30, thereby expanding the display portion 301 of the flexible display 30. Specifically, one end of the flexible display 30 is fixedly connected to the second portion 14, and the other end thereof passes through the first opening 1222 of the first portion 12 and is connected to the reel 20 disposed in the accommodating space 120.

In this manner, the spool 20 can rotate to release the flexible display 30 when the first and

second portions

12, 14 are moved apart, thereby expanding the display portion 301 of the flexible display 30. Therefore, the size of the screen display area of the mobile terminal 100 can be freely adjusted, the display part 301 of the flexible display screen 30 can be expanded to improve the operation experience of a user when a large screen is needed, and meanwhile, the display part 301 can not be expanded when the large screen is not needed, so that the whole machine is small in size and convenient to carry.

It will be appreciated that referring to fig. 5, in one instance, the first portion 12 and the second portion 14 are closely coupled together, in which case the display portion 301 of the flexible display 30 is not extended and the mobile terminal 100 is in the narrow screen mode, in which case a portion of the flexible display 30 is rolled up on the roller 20 and a portion is positioned above the first top plate 122 and exposed from the housing 10 for display. Note that in this embodiment, "the display portion 301 of the flexible display 30" may be understood as a portion located above the second top plate 142 of the second portion 14, that is, a portion exposed from the housing 10.

Referring to fig. 7, when the display portion 301 of the flexible display screen 30 needs to be expanded, the first portion 12 and the second portion 14 move away from each other, so that the second portion 14 drives one end of the flexible display screen 30 to move, and at this time, the reel 20 can release the flexible display screen 30, so that the display portion 301 of the flexible display screen 30 is enlarged, thereby improving the operation experience and the demand of the user. In such a case, the mobile terminal 100 is in the extended mode.

It will be appreciated that there are extreme positions in which the display area of the mobile terminal 100 is maximized, i.e., the area of the flexible display 30 exposed from the housing 10 is maximized, i.e., the area of the display portion 301 of the flexible display 30 is maximized, when both the second portion 14 and the first portion 12 are moved away from each other (as shown in fig. 7). When the first portion 12 and the second portion 14 are brought close together and coupled together, the display area of the mobile terminal 100 is minimized, i.e., the display portion 301 of the flexible display 30 is minimized in area (as shown in fig. 5).

One end of the flexible display 30 is fixedly connected to the second portion 14, which may mean that one end of the flexible display 30 is directly fixed to the second portion 14, or that the flexible display 30 is fixed to the second portion 14 through other mediums. One end of the flexible display screen 30 is not movable relative to the second portion 14.

Specifically, when the display area of the mobile terminal 100 needs to be expanded, that is, the display portion 301 of the display layer 32 needs to be expanded, the motor can drive the third transmission gear 744 to rotate, the third transmission gear 744 drives the first transmission gear 722 to rotate, the first transmission gear 722 drives the second portion 14 to move away from the first portion 12 through the rack portion 724, the second portion 14 drives one end of the flexible display screen 30 to move, meanwhile, the third transmission gear 744 can also drive the second transmission gear 742 to rotate at the same time, and then the scroll 20 is driven to rotate, so that the scroll 20 can release the flexible display screen 30 synchronously, and the purpose of expanding the display portion 301 of the flexible display screen 30 is achieved.

It can be understood that when the display portion 301 of the flexible display 30 needs to be reduced, the motor is only required to be reversely rotated so as to drive the second portion 14 to move relative to the first portion 12, in such a case, the second portion 14 gradually releases the flexible display 30, and the reel 20 can gradually roll up the flexible display 30.

It will be appreciated that in this embodiment, the travel of the second portion 14 per unit time is equal to the length of the flexible display 30 released by the rotation of the spool 20. That is, the spool 20 rotates to release the length of the flexible display 30 by the distance the end of the flexible display 30 is pulled by the second portion 14, which ensures that the flexible display 30 moves smoothly without wrinkles.

Furthermore, it can be further understood that, in some embodiments, in order to ensure the smoothness of rolling up and releasing the flexible display 30 by the roll 20, the number of the driving mechanisms 70 may be two, and the number of the rolls 20 is also two, and the two driving mechanisms 70 may be symmetrically disposed in the accommodating space 120 along the longitudinal direction of the mobile terminal 100 and respectively connected with the second portion 14, and also respectively connected with the two rolls 20. In this way, the synchronous and smooth rotation of the two reels 20 and the smooth movement of the second part 14 can be achieved by the synchronous driving of the two identical driving mechanisms 70, thereby ensuring the reliability of the movement of the mobile terminal 100 when expanding the display part 301 of the flexible display 30.

Furthermore, in other embodiments, the drive mechanism 70 may also include two synchronous motors disposed on the first portion 12, one of which is used to drive the second portion 14 relative to the first portion 12, and the other of which drives the spool 20, both using separate motors. Therefore, the two motors move synchronously, and the movement stability and the movement reliability of the flexible display screen 30 can also be ensured.

In addition, referring to fig. 17, in some embodiments, the driving mechanism 70 may also include a motor disposed on the first portion 12 and a first transmission structure 72 connected to the motor, the motor may drive the second portion 14 to move relative to the first portion 12 through the first transmission structure 72, and the second transmission structure 74 may be omitted.

Further, referring to fig. 18-21, in some embodiments, the mobile terminal 100 may further include a restoring mechanism 80, the restoring mechanism 80 may also be disposed in the accommodating space 120, the restoring mechanism 80 is connected to the reel 20, and the restoring mechanism 20 is configured to apply a restoring force to the flexible display 30 so as to keep the flexible display 30 in a tendency of being wound on the reel 20.

Specifically, the return mechanism 80 applies a return force to the roll 20, and the roll 20 maintains the tendency of the flexible display screen 30 to be wound onto the roll 20 by the return force. That is, when the second portion 14 is not moved relative to the first portion 12 by an external force, the restoring force of the restoring mechanism 80 may rotate the scroll 20, thereby rolling the end of the flexible display 30 onto the scroll 20, in which case the first portion 12 and the second portion 14 are completely fitted together and the mobile terminal 100 is in the narrow screen mode.

When the second portion 14 is subjected to an external force and the external force is greater than or equal to the restoring force of the restoring mechanism 80, the second portion 14 moves away from the first portion 12, so as to drive the reel 20 to rotate against the restoring force to release the flexible display 30, thereby expanding the display portion 301 of the flexible display 30.

It will be appreciated that due to the presence of the return mechanism 80, the return mechanism 80 will always apply a tension to the flexible display 30 during the expansion of the display portion 301 of the display layer 32, thereby allowing the flexible display to be folded and unfolded in balance, i.e., keeping the flexible display 30 flat at all times.

It will also be appreciated that in other embodiments, where the mobile terminal 100 includes the return mechanism 80, the driving mechanism 70 may also include the motor, the first transmission structure 72 and the second transmission structure 74 of the above embodiments, the first transmission structure 72 being connected to the second portion 12 of the motor, and the second transmission structure 74 being connected to the first transmission structure 72 and the reel 20. In such an embodiment, when the display area 301 needs to be reduced, the motor may not be operated, and the restoring force of the restoring mechanism 80 is used to rotate the reel 20 reversely to take up the flexible display 30 and move the second portion 14 relative to the first portion 12, i.e. close to the first portion 12.

Further, referring to fig. 19, the restoring mechanism 80 may include an elastic element connected to the spool 20 and configured to apply a restoring force to the spool 20. The resilient member may be a spring, such as a torsion spring as shown in fig. 19. Of course, the elastic element may also be an element having elastic restoring force, such as rubber, and is not limited herein.

Further, referring to fig. 20, in such an embodiment, the mobile terminal 100 may further include a detent structure 90, the detent structure 90 being disposed on the housing 10, the detent structure 90 being configured to limit rotation of the spool 20 when the second portion 14 is moved to a predetermined position relative to the first portion 12. That is, the detent structure 90 prevents the second portion 14 and the flexible display 30 from retracting under the restoring force of the restoring mechanism 80 when the second portion 14 is moved to a predetermined position relative to the first portion 12.

Specifically, referring to fig. 20, in the present embodiment, the locking structure 90 may include a locking block 92 formed on the first portion 12 and a locking groove 94 formed on the second portion 14, and when the second portion 14 moves to a predetermined position relative to the first portion 12, the locking block 92 is locked in the locking groove 94. Thus, even if the external force is removed from the second portion 14, the second portion 14 and the flexible display 30 will not be retracted by the restoring force of the restoring mechanism 80 due to the engagement of the latch 92 and the latch slot 94. To ensure that the mobile terminal 100 is in the extended mode.

It should be noted that the "preset position" may be a relative position between the second portion 14 and the first portion 12 when the two portions move away from each other to the limit position, or may be any position before the limit position.

It is understood that referring to fig. 21, in other embodiments, a slot 94 may be formed in first portion 12 and a latch 92 may be formed in second portion 14. In addition, in some embodiments, a latch may be formed on the first portion 12, a latch may be formed on the spool 20, and the latch may be engaged when the second portion 14 moves to the predetermined position, in which case, the latch and the latch may be engaged by a manual pressing manner or an electric driving manner, so that the spool does not rotate relative to the first portion, and the second portion 14 and the flexible display 30 do not retract under the action of the restoring mechanism 80. Of course, in other embodiments, the detent structure 90 can also include a detent, and the return mechanism 80 can include a torsion spring, which can be locked to counteract the return force of the torsion spring when the second portion 14 moves to the predetermined position. In addition, it is also understood that, in some embodiments, the detent structure 90 may also include an elastic component disposed on the first portion 12 and a first latching portion formed on the second portion 14, the elastic component may include a pressing piece, a spring and a second latching portion, the pressing piece is mounted on the first portion 12, the spring connects the pressing piece and the second latching portion, and the pressing piece may be used to drive the second latching portion to move to latch with the first latching portion under the action of external force through the spring, so as to define the relative position of the first portion 12 and the second portion 14. In this way, when the second portion 14 moves to the preset position, the user can keep the mobile terminal 100 in the extended mode by pressing the pressing piece to engage the first latching portion with the second latching portion, thereby preventing the second portion 14 from retracting under the restoring force of the restoring mechanism 80. It will be appreciated that when the press is pressed again, the first catch and the second catch are disengaged, thereby enabling the second portion 14 and the flexible display 30 to be retracted under the action of the return mechanism 80 to return the mobile terminal 100 from the extended mode to the narrow screen mode.

Referring to fig. 17, 18 and 22 again, in some embodiments, the mobile terminal 100 includes a telescopic support assembly 160, and the telescopic support assembly 160 is connected to the flexible display 30. The telescopic support assembly 160 can be elongated in the extending direction of the flexible display 30 to support the expanded portion of the flexible display 30.

In this way, the telescopic supporting component 160 can support the extension portion of the flexible display screen 30, so that the deformation degree of the flexible display screen 30 after being touched after being flattened from the reel 40 can be reduced, and the display effect of the flexible display screen 30 can be ensured. In addition, the telescopic support assembly 160 occupies a small space in the contracted state, which is beneficial to miniaturization of the mobile terminal 100.

It should be noted that the "expanded portion" can be understood as a portion of the flexible display 30 extending from the first portion 12 and flattening out during the process of moving the first portion 12 and the second portion 14 away from each other, i.e., an enlarged display portion of the flexible display 30. Hereinafter, the same or similar descriptions will be referred to for understanding.

It is to be appreciated that the telescoping support assembly 160 may also be collapsible, and the display portion 301 of the flexible display screen 30 may be at least partially supported on the telescoping support assembly 160 when the telescoping support assembly 160 is in the collapsed state. Alternatively, where the telescoping support assembly 160 is sufficiently long, the display portion 301 of the flexible display screen 30 may be supported on the telescoping support assembly 160. The telescoping support assembly 160 may extend as the flexible display 30 undergoes an expansion motion to support the expanded portion of the flexible display 30.

In some embodiments, one end of the telescoping support assembly 160 is fixedly connected to the first portion 12 and the other end is fixedly connected to the second portion 14 in the telescoping direction of the telescoping support assembly 160.

In this manner, the telescoping support assembly 160 can telescope as the first portion 12 and the second portion 14 move apart to support the flexible display 30. One end of the telescopic support assembly 160 may be fixedly connected to the first portion 12 by means of screws or the like, and the other end may be fixedly connected to the second portion 14 by means of screws or the like.

Specifically, referring to fig. 23 and 24, in some embodiments, the telescopic supporting assembly 160 includes a plurality of supporting members 161 and a telescopic member 162 connecting two adjacent supporting members 161. The plurality of supports 161 are linearly arranged. The leading support 161 is fixedly attached to the first portion 12 and the trailing support 161 is fixedly attached to the second portion 14. The telescopic member 162 can be extended and contracted in the extending direction of the flexible display 30, and the expanded portion of the flexible display 30 is supported on the support member 161 and the telescopic member 162 in the fully extended state of the telescopic support assembly 160.

It is understood that when the number of the supporting pieces 161 is greater than or equal to 3, the number of the expansion pieces 162 is greater than or equal to two. The fully extended state of the telescopic support assembly 160 means that the length of the telescopic support assembly 160 is at a maximum, and at this time, the flexible display 30 is also in a fully extended state due to the restriction of the telescopic support assembly 160. The expanded portion of the flexible display 30 is supported by the supporting member 161 and the telescopic member 162, so that the supporting area of the expanded portion of the flexible display 30 can be increased, which is further beneficial to reducing the deformation degree of the expanded portion of the flexible display 30.

In the case that the telescopic support assembly 160 is unfolded but not completely unfolded, the area of the expanded portion of the flexible display 30 is small, and at this time, the expanded portion of the flexible display 30 is supported on the support member 161, so that the support member 161 can also support the expanded portion of the flexible display 30, thereby reducing the deformation degree of the expanded portion of the flexible display 30.

Specifically, the support 161 may have a square shape, or may have other specific shapes. In the embodiment of the present application, the support 161 includes a first support part 163 and a connection second support part 164, and the flexible display screen 30 is supported on the first support part 163. The second support portion 164 may be supported on the first portion. The first support portion 163 and the second support portion 164 are connected to form a substantially "T" shape.

In some embodiments, the telescopic member 162 includes a plurality of connecting portions 165, the plurality of connecting portions 165 are sequentially rotatably connected, the first connecting portion 165 is rotatably connected to one of the two adjacent supporting members 161, the last connecting portion 165 is rotatably connected to the other of the two adjacent supporting members 161, and the plurality of connecting portions 165 are contracted by being rotatably folded and expanded by being rotatably unfolded.

In the fully extended state of telescoping support assembly 160, a surface 166 of each connection portion 165 facing flexible display screen 30 is flush with a surface 167 of support member 161 facing flexible display screen 30.

In this way, the telescopic supporting assembly 160 can extend and contract when the plurality of connecting portions 165 rotate, so that the supporting area of the flexible display screen 30 is larger.

In other embodiments, the connection portion 165 may be an elastic member. The elastic member may be formed to be elastically deformed to change its length, thereby changing the length of the telescopic support assembly 160.

In the embodiment of the present application, the extensible member 162 may include a pin (not shown) penetrating through the two adjacent connecting portions 165, so that the two adjacent connecting portions 165 may be rotatably connected.

As shown in the example of fig. 23, the number of the connecting portions 165 is two, and the two connecting portions 165 are folded in a substantially V-shape, and the telescopic support member 160 is in an incompletely unfolded state. When the two link members 165 are deployed in a substantially "one" configuration, the telescoping support assembly 160 is in a fully deployed configuration, as shown in FIG. 24. Of course, in other embodiments, the number of the connecting portions 165 may be three or more, or other specific numbers.

Further, a surface 166 of each connecting portion 165 facing the flexible display 30 and a surface of the support 161 facing the flexible display 30 are both flat surfaces 167.

In some embodiments, the telescopic support assembly 160 is located between the first top plate 122 and the flexible display screen 30, the support 161 is supported on the first top plate 122, and the first support 161 is fixedly connected to the first top plate 122. As such, the first top plate 122 may provide support for the support 161, so that the support 161 may stably support the expanded portion of the flexible display 30 when the flexible display 30 is touched, reducing the amount of deformation of the expanded portion of the flexible display 30.

Specifically, the first top board 122 is disposed opposite to the display portion 301 of the flexible display screen 30. It can be understood that, referring to fig. 17 and 18, when the first portion 12 and the second portion 14 move away from each other, a height difference exists between the upper surface of the first top board 122 and the upper surface of the second top board 142, and the flexible display 30 is fixedly connected to the upper surface of the second top board 142.

Therefore, the height of the telescopic support assembly 160 may fill the gap between the first top plate 122 and the flexible display screen 30, so that the expanded portion of the flexible display screen 30 can be kept flat when the flexible display screen 30 is in motion, thereby reducing the phenomena of pressing deformation, collapse and dislocation of the display layer 32 when being touched when the mobile terminal 100 is in the expanded mode, and improving the operation experience of the user.

In some embodiments, the second portion 14 includes a second top plate 142 disposed opposite the first top plate 122, a portion of the display portion 301 of the flexible display screen 30 is attached to the second top plate 142, and the trailing support 161 is fixedly attached to the second top plate 142. In this manner, the telescopic support assembly 160 may be telescopic with the movement of the second top plate 142, thereby supporting the expanded portion of the flexible display screen 30.

It is understood that the display portion 301 of the flexible display 30 includes an expansion portion when the flexible display 30 is in the expanded state (expanded mode). If the telescopic support assembly 160 is long enough to support the display portion 301 of the flexible display 30 in the contracted state, the second top plate 142 may be omitted. At this time, the telescopic support assembly 160 may also support the expanded portion of the flexible display 30 in the extended state.

It should be noted that in the examples of fig. 17 and 18, the mobile terminal 100 omits the stopper 40 and the driving mechanism 70, and at this time, the second portion 14 may be manually pulled to expand the display portion 301 of the flexible display 30 and extend the telescopic support assembly 160.

In the example of fig. 15 and 16, the mobile terminal 100 includes the first transmission gear 722, and at this time, a motor may drive the first transmission gear 722 to rotate to drive the second portion 14 to rotate, so as to expand the display screen portion 301 of the flexible display screen 30 and extend the telescopic support assembly 160. Another motor may drive the reel 20 to rotate to release the flexible display screen 30.

In the example of fig. 5 and 7, the mobile terminal 100 may move the second portion 14 synchronously with the reel 20 through the first, second, and third transmission gears 722, 724, 744, thereby expanding the display screen portion 301 of the flexible display screen 30 and extending the telescopic support assembly 160, and causing the reel 20 to release the flexible display screen 30.

Referring to fig. 4 to 7, the operation principle of the mobile terminal 100 according to the present embodiment will be described.

As described above, the mobile terminal 100 can switch between the narrow screen mode and the extended mode. In the states shown in fig. 4 and 5, the mobile terminal 100 is in the narrow screen mode, and in the states shown in fig. 6 and 7, the mobile terminal 100 is in the extended mode. When in the narrow screen mode, the first part 12 and the second part 14 cooperate with each other to form the housing 10, one end of the flexible display 30 is rolled up on the reel 20, and the other end is connected to the second part 14, at this time, only a smaller part of the flexible display 30 is exposed out of the housing 10, and the display part 301 is narrower, so that the display device is convenient for a user to carry.

When a user needs a larger display portion 301, the driving mechanism 70 can drive the second portion 14 to move away from the first portion 12, at this time, the second portion 14 drives one end of the flexible display 30 to move, and at the same time, the driving mechanism 70 also drives the reel 20 to rotate and release the flexible display 30, so that the portion of the flexible display 30 hidden in the housing 10 is gradually pulled out by the second portion 14 (i.e., moves from the state shown in fig. 4 to the state shown in fig. 6), thereby achieving the purpose of expanding the display portion 301 of the flexible display 30, and at this time, the area of the display portion 301 is larger, which can facilitate the user operation to improve the operation experience of the user. At the same time, the telescopic support assembly 160 is extended to support the expanded portion of the flexible display screen 30.

When the expansion mode needs to be switched to the narrow-screen mode, the motor of the driving mechanism 70 is only required to be rotated reversely to drive the second portion 14 to move oppositely relative to the first portion 12, so as to release the flexible display screen 30, at this time, the reel 20 is also rotated reversely correspondingly to synchronously roll up the flexible display screen 30, when the flexible display screen moves to the limit position of the opposite movement between the first portion 12 and the second portion 14, the motor stops operating, and the mobile terminal 100 returns to the narrow-screen mode.

In summary, the mobile terminal 100 according to the embodiment of the present application includes a housing 10, a scroll 20, a flexible display 30, and a telescopic support assembly 160. The housing 10 includes a first portion 12 and a second portion 14 that are capable of relative movement. The spool 20 is rotatably disposed in the first portion 12. One end of the flexible display 30 is connected to the second part 14 and the other end is rolled up on the roll 20. Upon a movement of the first and

second portions

12, 14 away from each other, the roller 20 can be rotated to release the flexible display screen 30, thereby expanding the display portion 301 of the display layer 32. The telescoping support assembly 160 is coupled to the flexible display screen 30. The telescopic support assembly 160 can be elongated in the extending direction of the flexible display 30 to support the expanded portion of the flexible display 30.

In the mobile terminal 100 according to the embodiment of the present disclosure, the telescopic supporting component 160 may support the extension portion of the flexible display 30, so as to reduce the deformation degree of the flexible display 30 after being touched after being flattened from the reel 40, thereby ensuring the display effect of the flexible display 30. In addition, the telescopic support assembly 160 occupies a small space in the contracted state, which is beneficial to miniaturization of the mobile terminal 100.
