Fig. 1 is a schematic structural diagram of a display device according to an embodiment of the present invention, fig. 2 is another schematic structural diagram of the display device according to the embodiment of the present invention, fig. 3 is a relative position diagram of a housing 21, a reel 22, and a flexible display 10 located in the housing 21, where fig. 1 shows a contracted state of the flexible display 10 in the display device, fig. 2 shows a stretched state of the flexible display 10 in the display device, and fig. 3 shows a perspective structure of a receiving portion 20. In the collapsed state, a portion of the flexible display screen 10 is wound around the roller 22 in the housing 21, and another portion is located outside the housing 21 and on a side of the support structure 50 facing away from the slide rail 40. In the stretched state, at least a portion of the flexible display screen 10 originally wound on the reel 22 extends outside the housing 21, so that the size of the flexible display screen 10 located above the support structure 50 becomes large.
Referring to fig. 1 to fig. 3, an embodiment of the invention provides a display device 100, including:
a flexible display screen 10 includes opposing first and second ends 11, 12.
A receiving portion 20 including a housing 21 and a reel 22, wherein the reel 22 is located in the housing 21, the first end portion 11 is fixed on the reel 22, and at least a portion of the flexible display screen 10 can be wound on the reel 22 and wound or unwound according to the rotation of the reel 22; please refer to fig. 3.
The peripheral part 30 is positioned outside the shell 21 and comprises a sliding rail 40 and a supporting structure 50 connected with the sliding rail 40, and at least part of the flexible display screen 10 is positioned on one side of the supporting structure 50, which faces away from the sliding rail 40; the supporting structure 50 includes a plurality of supporting portions 55 arranged along a first direction D1, the supporting portions 55 include a first fixed supporting portion 51 and a second fixed supporting portion 52, and a plurality of slidable supporting portions 53 located between the first fixed supporting portion 51 and the second fixed supporting portion 52 along a first direction D1, wherein the second fixed supporting portion 52 is located on a side of the first fixed supporting portion 51 away from the casing 21, the first fixed supporting portion 51 is fixed with the casing 21, the second end portion 12 is fixed with the second fixed supporting portion 52, and the first direction D1 is an extending direction of the slide rail 40;
the sliding rail 40 and the supporting structure 50 may move the flexible display screen 10 to stretch or contract along the first direction D1.
Specifically, referring to fig. 1 to fig. 5, in the display device 100 provided in the embodiment of the present invention, a retractable slide rail 40 and a support portion 55 capable of moving on the slide rail 40 are introduced, and the flexible display screen 10 can be stretched or contracted by the slide rail 40 and the support portion 55. In a contracted state of the flexible display screen 10, please refer to fig. 4 and 5, the sliding rail 40 is in a contracted state, and the supporting portions 55 on the sliding rail 40 are also in a contracted state, that is, the interval between the adjacent supporting portions 55 is small or the adjacent supporting portions 55 are close together, at this time, a part of the flexible display screen 10 is wound on the reel 22 in the housing 21, and the size of the flexible display screen 10 above the supporting portions 55 is small, so that a small-size display function can be realized, and the flexible display screen is also convenient to store, wherein fig. 4 is a schematic structural view of the display device provided by the embodiment of the present invention in the contracted state, and fig. 5 is a schematic structural view of the sliding rail 40 in the contracted state in the display device provided by the embodiment of the present invention.
In the stretched state of the flexible display screen 10, for example, referring to fig. 6 and fig. 7, and with reference to fig. 2 to fig. 3, the slide rail 40 is in the stretched state, the first fixed support 51 of the support 55 is fixed relative to the housing 21, the slide support 55 can move in the first direction D1 in the slide rail 40 under the driving of the second fixed support 52, since the second end 12 of the flexible display 10 is fixed to the second fixed support 52, the movement of the support 55 will cause the flexible display 10 to unwind from the reel 22, the area of the flexible display screen 10 above the supporting part 55 is enlarged, the display area is enlarged, thereby meeting the display requirement of a large screen, fig. 6 is a schematic structural diagram of a display device in a stretched state according to an embodiment of the present invention, fig. 7 is a schematic structural diagram of a slide rail 40 in a display device according to an embodiment of the invention in a stretched state. It should be noted that the first fixing support 51 in the embodiment of the present invention means that the support 55 is fixed with respect to the housing 21, and the second fixing support 52 means that the support 55 is fixed with respect to the second end 12 of the flexible display 10.
In particular, since the present invention introduces the support portion 55 at the side of the flexible display 10 not wound on the reel 22 facing the slide rail 40, in the contracted state, the support portion 55 is also in the contracted state, and can provide a better support for the flexible display 10 thereon. When the flexible display screen 10 is stretched, although the interval between two adjacent supporting portions 55 changes, the supporting portions 55 are still located right below the flexible display screen 10, and can still support the flexible display screen 10 in the stretched state, even if the flexible display screen 10 is pressed in the stretched state, the problems of deformation and the like cannot occur or hardly occur, so that the supporting reliability and the fixing reliability of the flexible display screen 10 in the stretched state are greatly improved, and the problem of abnormal display caused by the deformation of the flexible display screen 10 which may occur when the flexible display screen is unreliably supported is effectively improved.
Fig. 8 is a schematic structural diagram of a stretched state when the position limiting structure 60 is introduced into the display device, and fig. 9 is a schematic structural diagram of a contracted state when the position limiting structure 60 is introduced into the display device, wherein fig. 8 and 9 show a non-light-emitting surface of the display device, i.e., a surface (a back surface) on which the flexible display screen 10 is not disposed.
Referring to fig. 8 and 9, in an alternative embodiment of the present invention, the display device provided in the embodiment of the present invention further includes a limiting structure 60, at a side of the supporting structure 50 facing the sliding rail 40, two adjacent supporting portions 55 are connected by at least one limiting structure 60, and the limiting structure 60 is used for controlling a distance between two adjacent supporting portions 55.
Specifically, the embodiment of the present invention introduces at least one position-limiting structure 60 between two adjacent support portions 55, the same position-limiting structure 60 is respectively connected to the two adjacent support portions 55, when the two adjacent support portions 55 are relatively displaced, the position of the position-limiting structure 60 connecting the two support portions 55 will also be changed, for example, when the width of the space between the two adjacent support portions 55 is gradually increased, the position-limiting structure 60 will be able to limit the maximum space therebetween, that is, the space between the two adjacent support portions 55 cannot be infinitely increased, and when the space therebetween is too large, the supporting effect on the flexible display screen 10 in the stretching state will be weakened. Therefore, the embodiment of the present invention introduces the limiting structure 60 connecting two adjacent supporting portions 55 to limit the interval between the slidable supporting portions 53, which is beneficial to ensuring the supporting effect of the supporting portions 55 on the flexible display screen 10.
Optionally, the limiting structure 60 provided in the embodiment of the present invention may limit the maximum interval between two adjacent supporting portions 55, but does not limit the minimum interval between two adjacent supporting portions 55, that is, even if the limiting structure 60 is introduced, the minimum interval between two adjacent supporting portions 55 in the contracted state is not affected, for example, in the minimum contracted state, two adjacent supporting portions 55 can still contact each other, and can still support the flexible display screen 10.
Referring to fig. 10 in conjunction with fig. 8 and 9, in fig. 10, a schematic connection diagram of the limiting structure 60 and the supporting portion 55 is shown, and in an alternative embodiment of the present invention, the limiting structure 60 includes a sliding rod 66 and a first protruding portion 61 located on a surface of the supporting portion 55 facing the sliding rail 40, and the same sliding rod 66 is slidably connected to the corresponding first protruding portions 61 of two adjacent supporting portions 55.
Specifically, the present invention introduces a sliding rod 66 and a first protruding portion 61 on the slidable supporting portion 53 as the limiting structure 60, the sliding rod 66 and the first protruding portion 61 are both located on a side of the slidable supporting portion 53 away from the flexible display screen 10, and the sliding rods 66 are respectively connected with the first protruding portions 61 on two adjacent supporting portions 55 in a sliding manner. When a relative displacement occurs between two adjacent support portions 55, i.e., when the interval between two adjacent support portions 55 changes, the slide rod 66 will be able to move relative to the first boss portion 61. When the flexible display screen 10 is stretched, because the maximum distance between the first protruding portions 61 fixed on the two adjacent supporting portions 55 is fixed, when the relative position relationship between the two adjacent first protruding portions 61 reaches the maximum distance, the distance between the two corresponding supporting portions 55 cannot be further increased, which is equivalent to defining the maximum distance between the two adjacent supporting portions 55, and avoiding that the flexible display screen 10 cannot be effectively supported due to the overlarge gap between the two supporting portions. In addition, since the sliding rod 66 has a certain rigidity and the length thereof does not change with the movement of the slidable support portion 53, the distance between two first protruding portions 61 connected thereto can be defined in cooperation with the first protruding portions 61, and the width of the space between two adjacent support portions 55 can be precisely defined.
Alternatively, referring to fig. 10, the first protruding portion 61 is embodied as an elongated protruding structure located on a side of the slidable support portion 53 facing away from the flexible display screen 10, and an extending direction of the first protruding portion 61 is the same as an extending direction of the corresponding support portion 55. Alternatively, along the first direction D1, the width of the first protruding portion 61 is smaller than the width of the supporting portion 55, so that the width of the space between two adjacent first protruding portions 61 is always larger than the width of the space between two adjacent supporting portions 55, and thus a space can be reserved for the movement of the supporting rod, even when two adjacent supporting portions 55 contact each other in the contracted state, a space capable of accommodating the sliding rod 66 still remains between two adjacent first protruding portions 61, so that the introduction of the supporting rod does not affect the size of the peripheral portion 30 in the contracted state, and the small size requirement of the display device in the contracted state can still be ensured.
Alternatively, a slide groove is provided in a side surface of the first boss portion 61, i.e., a side surface of the first boss portion 61 facing another first boss portion 61 adjacent thereto, in which one end of the slide rod 66 is located to be slidable; the other end of the slide bar 66 is located in and slidable in the slide groove of the adjacent other first boss portion 61. When the display device is in a shrinking or stretching process, two ends of the same sliding rod 66 respectively displace in the two sliding grooves, so that an included angle between the sliding rod 66 and the corresponding supporting portion 55 changes, for example, in a shrinking state, the included angle between the sliding rod 66 and the supporting portion 55 is the smallest; in the stretched state, the angle between the sliding rod 66 and the support 55 is at a maximum, for example, 90 °.
Alternatively, in the embodiment of the present invention, the first fixed support 51, the second fixed support 52 and the slidable support 53 may be provided with the corresponding first protruding portion 61 and the sliding rod 66, so that the distance between any two adjacent supports 55 can be defined by the sliding rod 66.
Alternatively, the length of the sliding rod 66 and the length of the sliding groove corresponding to each support portion 55 are the same.
With continued reference to fig. 8-10, in an alternative embodiment of the present invention, the flexible display screen 10 includes a stretched state and a contracted state, in the same stretched state or the same contracted state, the extending directions of the sliding rods 66 are the same or parallel, and the distance between any two adjacent supporting portions 55 is equal.
Specifically, the embodiment of the present invention will be described by taking as an example that the orthogonal projection shape of the slide bar 66 on the plane where the support portion 55 is located is a rectangle. When the interval between the adjacent two support portions 55 is changed, the extending direction of the sliding rod 66 connecting the adjacent two support portions 55 is also changed, and when the interval between the adjacent two support portions 55 reaches the maximum interval, the extending direction of the sliding rod 66 becomes the first direction D1. The present invention defines that the extending directions of the sliding rods 66 are the same or parallel in the same stretching state or the same shrinking state, so that the widths of the intervals between any two adjacent supporting portions 55 are the same, that is, the slidable supporting portions 53 are uniformly arranged in both the stretching state and the shrinking state, so as to uniformly support the flexible display screen 10, and the flexible display screen 10 is better supported, thereby avoiding the situation of poor local supporting effect.
Fig. 11 is another schematic structural view showing a stretched state when the stopper structure 60 is introduced into the display device, fig. 12 is another schematic structural view showing a contracted state when the stopper structure 60 is introduced into the display device, and fig. 13 is another schematic structural view showing connection between the stopper structure 60 and the support portion 55. This embodiment shows another version of a spacing structure 60 in a display device.
Referring to fig. 11 to 13, in an alternative embodiment of the present invention, the limiting structure 60 includes an elastic component 69 and first protruding portions 61 located on the surfaces of the supporting portions 55 facing the sliding rail 40, and two ends of the same elastic component 69 are respectively fixed to the first protruding portions 61 corresponding to two adjacent supporting portions 55.
Specifically, the limiting structure 60 in the embodiment of the present invention is embodied as the elastic member 69 and the first protruding portion 61, when the flexible screen is in the contracted state, the interval between two adjacent supporting portions 55 is minimum, and at this time, the elastic member 69 is in the compressed state; when the flexible screen is in a stretched state, the elastic member 69 will also stretch, and for the elastic member 69, the deformation amount thereof has a limit value, and when the elastic member 69 is stretched to a degree that the elastic member cannot be further deformed, the length between two adjacent supporting portions 55 connected to the elastic member 69 will also become maximum, and the display size of the corresponding flexible display screen 10 will become maximum. That is, the maximum interval between two adjacent supporting portions 55 can also be limited by the elastic member 69, so that the supporting effect of the flexible display screen 10 is prevented from being reduced due to the excessively large interval between two adjacent supporting portions 55.
Referring to fig. 11 to 13, in an alternative embodiment of the present invention, the flexible display panel 10 includes a stretching state and a shrinking state, and in the same stretching state or the same shrinking state, deformation amounts of the elastic members 69 are the same, and a distance between any two adjacent supporting portions 55 is equal.
Specifically, when the deformation amount of each elastic component 69 is the same in the same stretching state or the same shrinking state, it can be ensured that the interval between any two supporting portions 55 connected to the elastic component 69 is the same, and the slidable supporting portions 53 are arranged at equal intervals, that is, the slidable supporting portions 53 are uniformly arranged, so that the uniformly arranged slidable supporting portions 53 can provide uniform supporting force for the flexible display screen 10, and the problem of insufficient supporting force at the local position of the flexible display screen 10 is avoided, thereby being beneficial to improving the supporting reliability and the fixing reliability of the flexible display screen 10 in the display device.
Alternatively, the elastic member 69 according to the embodiment of the present invention is a spring.
Alternatively, referring to fig. 13, one end of the elastic member 69 is fixed to the side of the first protruding portion 61, that is, the side of the first protruding portion 61 facing to the other adjacent first protruding portion 61, and the other end is fixed to the side of the other adjacent first protruding portion 61 adjacent to the first protruding portion 61, when the display device is contracted or stretched, the elastic member 69 will deform, so that the distance between the two adjacent supporting portions 55 changes.
Alternatively, referring to fig. 13, the first protruding portions 61 are implemented as elongated protruding structures located on a side of the support portion 55 facing away from the flexible display screen 10, and an extending direction of the first protruding portions 61 is the same as an extending direction of the corresponding support portion 55. Alternatively, along the first direction D1, the width of the first protruding portion 61 is smaller than the width of the supporting portion 55, so that the width of the space between two adjacent first protruding portions 61 is always larger than the width of the space between two adjacent supporting portions 55, so as to reserve a space for the elastic member 69 to move, even when two adjacent supporting portions 55 contact each other in the contracted state, there is still a space between two adjacent first protruding portions 61 for accommodating the elastic member 69, so that the introduction of the elastic member 69 does not affect the size of the peripheral portion 30 in the contracted state, and the small size requirement of the display device in the contracted state can be ensured.
Fig. 14 is a schematic structural diagram of a side of a slide rail 40 in a display device according to an embodiment of the present invention, fig. 15 is a schematic structural diagram of a side of a slide rail 40 in a display device according to an embodiment of the present invention, and this embodiment shows a scheme of introducing a rotating portion 80 into a display device.
Referring to fig. 14 and 15, in an alternative embodiment of the present invention, the sliding rail 40 includes a first sliding rail structure 41 corresponding to the first fixed supporting portion 51, the display device further includes a rotating portion 80, and the rotating portion 80 is slidably connected to the first sliding rail structure 41; when the flexible display screen 10 is stretched or contracted, the rotating portion 80 rotates relative to the first slide rail structure 41.
Specifically, the slide rail 40 provided in the embodiment of the present invention includes the first slide rail structure 41 corresponding to the first fixed support portion 51, and the first slide rail structure 41 can be regarded as the slide rail 40 closest to the housing 21 compared to other slide rail 40 structures. Optionally, the first slide rail structure 41 may correspond to at least one slidable supporting portion 53 in addition to the first fixed supporting portion 51. In the embodiment of the invention, the rotating portion 80 slidably connected to the first sliding rail structure 41 is introduced into the display device, and when the rotating portion 80 rotates, the first sliding rail structure 41 can be driven to displace along the first direction D1. For example, in the contracted state, the sliding portion 44 is embodied in a structure as shown in fig. 14, the extending direction of which intersects with the first direction D1; during stretching, the rotating portion 80 rotates, and the first slide rail structure 41 moves in a direction away from the housing 21 with the rotation of the rotating portion 80, and the corresponding slidable support portion 53 moves in a direction away from the housing 21. When the rotating portion 80 rotates to the first direction D1, the supporting range of the supporting plate is further expanded, so that the display area of the flexible display screen 10 is further expanded.
Fig. 16 is a schematic view of the slide rail 40 and the supporting portion 55 according to the embodiment of the present invention, please refer to fig. 5, 7 and 16, in an alternative embodiment of the present invention, the slide rail 40 includes a plurality of telescopic sliding portions 44 connected to each other, and the telescopic sliding portions 44 include sliding slots 42 disposed toward the supporting portion 55; the side of the support portion 55 facing the slide rail 40 comprises a second projection 59, the second projection 59 being located in the slide groove 42.
Specifically, in the embodiment of the present invention, the sliding rail 40 includes a plurality of telescopic sliding portions 44 connected to each other, where the connection is not a fixed connection, but can be embodied as a sliding connection, that is, two adjacent telescopic sliding portions 44 can be relatively displaced to change the total length of the overall sliding slot 42 on the sliding rail 40, thereby assisting in changing the actual display area of the flexible display screen 10. Optionally, the retractable sliding portion 44 of the embodiment of the present invention includes a sliding slot 42 disposed toward the supporting portion 55, and a side of the supporting portion 55 facing the sliding rail 40 includes a second protruding portion disposed in the sliding slot 42 and capable of sliding in the sliding slot 42, so as to drive the slidable supporting portion 53 to slide. In the embodiment of the present invention, the supporting portion 55 is matched with the sliding groove 42 through the second protruding portion 59, which is beneficial to avoiding the falling-off phenomenon between the supporting portion 55 and the sliding rail 40, so as to be beneficial to improving the stretching reliability of the display device in the stretching process and the shrinking reliability of the display device in the shrinking process.
Fig. 17 is a schematic structural diagram of a sliding rail 40 provided in an embodiment of the present invention in a contracted state, fig. 18 is a schematic structural diagram of the sliding rail 40 provided in the embodiment of the present invention in a stretched state, and the embodiment takes the sliding rail 40 as a sleeve structure for example.
Referring to fig. 17 and 18, in an alternative embodiment of the present invention, the retractable sliding portion 44 is a retractable sleeve structure, and in the retracted state of the flexible display screen, any two adjacent retractable sliding portions 44 include a first sliding portion 45 and a second sliding portion 46, and at least a portion of the first sliding portion 45 is inserted into the second sliding portion 46.
In particular, when the telescopic sliding part 44 in the slide rail 40 is embodied as a telescopic sleeve structure, the length change of the slide rail 40 is made more flexible. In any two adjacent telescopic sliding parts 44, the size of the first sliding part 45 is smaller than that of the second sliding part 46, at least part of the first sliding part 45 is nested inside the second sliding part 46, and the length of the sliding rail 40 can be changed by changing the relative position relationship between the first sliding part 45 and the second sliding part 46, for example, when most of the first sliding part 45 is nested in the second sliding part 46, the length of the corresponding sliding rail 40 is reduced; when most of the area of the first sliding portion 45 moves out of the second sliding portion 46, the length of the corresponding slide rail 40 increases, so that the length of the slide rail 40 can be flexibly controlled by controlling the relative position relationship between the first sliding portion 45 and the second sliding portion 46.
Referring to fig. 4, 5 and 16, in an alternative embodiment of the present invention, the height of the second protrusion/59 in the sliding slot of the second sliding portion 46 is greater than the height of the second protrusion 59 in the sliding slot of the first sliding portion 45.
When the chute of the embodiment of the present invention is formed by using the sleeve structure, since the size of the first sliding portion 45 in two adjacent retractable sliding portions 44 is smaller than that of the second sliding portion 46, and it may happen that the height of the sliding rail 40 corresponding to the first sliding portion 45 is smaller than that of the sliding rail 40 corresponding to the second sliding portion 46, the embodiment of the present invention sets the height of the second protruding portion in the chute of the second sliding portion 46 to be greater than that of the second protruding portion in the chute of the first sliding portion 45, so that the slidable supporting portions 53 corresponding to the first sliding portion 45 and the second sliding portion 46 are located on the same plane toward the surface of the flexible display screen 10, thereby providing better support for the flexible display screen and ensuring that the display surface of the flexible display screen is a flat surface.
In an alternative embodiment of the present invention, please refer to fig. 1 to 5, the surfaces of the supporting portions 55 departing from the sliding rail 40 are located on the same plane.
Specifically, the surfaces of the support portions 55 departing from the slide rail 40 are arranged on the same plane, so that the support portions 55 can provide a flat support surface for the flexible display screen 10, which is beneficial to improving the support effect of the flexible display screen 10. When the sliding rail 40 with the sleeve structure is adopted, the second protruding portion connected to the supporting portion 55 can be designed differently, so that the surfaces of the supporting portion 55 facing away from the sliding rail 40 are located on the same plane. Of course, in some other embodiments of the invention, the surface of the support portion 55 facing away from the slide rail 40 may also be located on the same plane by designing the thickness of the support portion 55 differently, for example, the thickness of the support portion 55 corresponding to the second sliding portion 46 is designed to be larger than the thickness of the support portion 55 corresponding to the first sliding portion 45, so as to compensate for the height difference caused by the size of the sleeve. Of course, the height of the first protruding portion connected to the supporting portion 55 and the thickness of the supporting portion 55 can be designed differently to compensate for the height difference, so that the surfaces of the supporting portion 55 departing from the sliding rail 40 are located on the same plane.
In an alternative embodiment of the present invention, please refer to fig. 1 and fig. 4, a side of the flexible display screen 10 facing the supporting structure 50 is provided with an absorption layer 90, when the distance between the second fixing and supporting portion 52 and the housing 21 is constant, the absorption layer 90 absorbs the supporting portion 55; when the second fixing support 52 is displaced relative to the housing 21, the adsorption layer 90 is disengaged from the support 55.
Referring to fig. 1, in the embodiment of the present invention, an absorption layer 90 is introduced on a surface of the flexible display 10 facing the supporting structure 50, the absorption layer 90 is fixed to the surface of the flexible display 10 facing the supporting structure 50, and when the flexible display 10 is stretched, the absorption layer 90 is stretched; when the flexible display screen 10 contracts, the absorbent layer 90 contracts therewith. Optionally, the absorbent layer 90 covers the entire surface of the flexible display 10 facing the support structure 50. When the flexible display screen 10 contracts or stretches to a certain size for displaying images, and does not contract or stretch temporarily (i.e. under the condition that the distance between the second fixing and supporting portion 52 and the housing 21 is fixed), the adsorption layer 90 adsorbs to the supporting portion 55, so that the flexible display screen 10 is fixed on the surface of the supporting portion 55 departing from the slide rail 40, and the fixing reliability of the flexible display screen 10 in the display process is improved. When the flexible display screen 10 is in a moving state relative to the housing 21 (i.e. the second fixing support 52 is displaced relative to the housing 21, i.e. the second end portion 12 of the flexible display screen 10 moves relative to the housing 21), the adsorption force between the adsorption layer 90 and the support portion 55 is eliminated, so as to achieve smooth stretching or shrinking of the flexible display screen 10.
In an alternative embodiment of the present invention, the absorption layer 90 is a magnetic layer, and the support portion 55 comprises a magnetic material; the adsorption layer 90 generates an adsorption force under the control of an electrical signal.
When the flexible display screen 10 needs to be fixed with the support part 55, the adsorption layer 90 can be controlled to generate adsorption force through an electric signal; when the flexible display screen 10 needs to be stretched or shrunk, the electric signal can be cancelled to cancel the adsorption force on the adsorption layer 90, so that the support portion 55 and the flexible layer are no longer adsorbed to each other.
In summary, the display device provided by the invention at least achieves the following beneficial effects:
the display device provided by the invention introduces the slide rail and the support structure connected with the slide rail, wherein the support structure comprises a first fixed support part, a second fixed support part and a plurality of slidable support parts positioned between the first fixed support part and the second fixed support part, the slidable support parts can slide on the slide rail, the first end part of the flexible display screen is fixed on the scroll, the second end part of the flexible display screen is fixed with the second fixed support part, and when the second fixed support part is displaced relative to the shell, the slidable support parts slide on the slide rail to drive the flexible display screen to contract or stretch. When the flexible display screen is contracted, at least part of the flexible display screen is wound on the reel to reduce the size of the display device, so that the display device is more portable; when the flexible display screen is stretched, the display area of the display device can be increased, and the display device is portable and meets the requirement of large-size display. Particularly, the support part is introduced to one side of the flexible display screen, which faces the slide rail, of the part of the flexible display screen, which is not wound on the scroll, so that when the flexible display screen is stretched, the support part can support the flexible display screen in a stretching state, and the flexible display screen cannot deform even if being pressed, so that the support reliability and the fixing reliability of the flexible display screen in the stretching state are greatly improved, and the problem of abnormal display caused by deformation of the flexible display screen possibly occurring when the flexible display screen is not supported reliably is effectively solved.
