In the contracted state, a portion of the flexible display screen 10 is wound on the spool 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 10 originally wound on the reel 22 extends outside the housing 21, so that the flexible display 10 located above the support structure 50 becomes larger in size.
Referring to fig. 1 to 3, an embodiment of the present application provides a display device 100, including:
the flexible display screen 10 includes opposed first and second ends 11, 12.
A housing portion 20 including a housing 21 and a reel 22, the reel 22 being located within the housing 21, the first end 11 being fixed to the reel 22, at least a portion of the flexible display 10 being windable around the reel 22, the winding or unwinding being dependent on the rotation of the reel 22; please refer to fig. 3.
A peripheral portion 30, located outside the housing 21, comprising a sliding rail 40 and a support structure 50 connected to the sliding rail 40, at least part of the flexible display screen 10 being located on a side of the support structure 50 facing away from the sliding rail 40; the support structure 50 includes a plurality of support portions 55 arranged along a first direction D1, the support portions 55 including a first fixed support portion 51 and a second fixed support portion 52, and a plurality of slidable support portions 53 located between the first fixed support portion 51 and the second fixed support portion 52 along the first direction D1, wherein the second fixed support portion 52 is located at a side of the first fixed support portion 51 away from the housing 21, the first fixed support portion 51 is fixed to the housing 21, the second end portion 12 is fixed to the second fixed support 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 can drive the flexible display screen 10 to stretch or shrink along the first direction D1.
Specifically, referring to fig. 1 to 5, in the display device 100 provided by the embodiment of the application, a telescopic sliding rail 40 and a supporting portion 55 capable of moving on the sliding rail 40 are introduced, and the flexible display screen 10 can be stretched or contracted under the driving of the sliding rail 40 and the supporting portion 55. In the contracted state of the flexible display screen 10, please refer to fig. 4 and fig. 5, the sliding rail 40 is in the contracted state, the supporting portions 55 on the sliding rail 40 are also in the contracted state, that is, the adjacent supporting portions 55 are spaced less or the adjacent supporting portions 55 are abutted together, at this time, a part of the flexible display screen 10 is wound on the reel 22 in the housing 21, the flexible display screen 10 above the supporting portions 55 has a smaller size, which can realize a small-size display function and is convenient for storage, wherein fig. 4 is a schematic structural diagram of the display device in the contracted state provided by the embodiment of the application, and fig. 5 is a schematic structural diagram of the sliding rail 40 in the contracted state provided by the embodiment of the application.
In the stretched state of the flexible display screen 10, for example, please refer to fig. 6 and fig. 7, and refer to fig. 2 to fig. 3, in which the sliding rail 40 is in a stretched state, the first fixed supporting portion 51 in the supporting portion 55 is fixed relative to the housing 21, the sliding supporting portion 55 is driven by the second fixed supporting portion 52 to move along the first direction D1 in the sliding rail 40, and since the second end 12 of the flexible display screen 10 is fixed to the second fixed supporting portion 52, the moving process of the supporting portion 55 drives the flexible display screen 10 to unwind from the reel 22, so that the area of the flexible display screen 10 above the supporting portion 55 is enlarged, and the display area is enlarged, thereby meeting the display requirement of the large screen, wherein fig. 6 is a schematic structural diagram of the display device in the stretched state in the embodiment of the display device provided by the application, and fig. 7 is a schematic structural diagram of the sliding rail 40 in the stretched state in the display device provided by the embodiment of the application. It should be noted that, in the embodiment of the present application, the first fixed supporting portion 51 refers to the supporting portion 55 being fixed relative to the housing 21, and the second fixed supporting portion 52 refers to the supporting portion 55 being fixed relative to the second end 12 of the flexible display screen 10.
In particular, since the support portion 55 is introduced to the side of the slide rail 40 at the portion of the flexible display screen 10 which is not wound on the reel 22, the support portion 55 is also in the contracted state, so that the flexible display screen 10 positioned thereon can be supported better. When the flexible display screen 10 is stretched, although the interval between two adjacent supporting parts 55 is changed, the supporting parts 55 are still positioned right below the flexible display screen 10, and still can play a role in supporting the flexible display screen 10 in a stretched state, and even if the flexible display screen 10 is pressed in the stretched state, the flexible display screen 10 is not deformed or hardly deformed, 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 that the flexible display screen 10 is deformed possibly in the unreliable state of supporting to cause abnormal display is effectively improved.
Fig. 8 is a schematic view of a structure in a stretched state when the limit structure 60 is introduced into the display device, and fig. 9 is a schematic view of a structure in a contracted state when the limit structure 60 is introduced into the display device, wherein fig. 8 and 9 show a non-light-emitting surface of the display device, that is, a surface (back surface) where the flexible display screen 10 is not provided.
Referring to fig. 8 and 9, in an alternative embodiment of the present application, the display device further includes a limiting structure 60, where two adjacent supporting portions 55 are connected by at least one limiting structure 60 on a side of the supporting structure 50 facing the sliding rail 40, and the limiting structure 60 is used for controlling a distance between the two adjacent supporting portions 55.
Specifically, in the embodiment of the present application, at least one limiting structure 60 is introduced between two adjacent supporting portions 55, the same limiting structure 60 is respectively connected to two adjacent supporting portions 55, when two adjacent supporting portions 55 are relatively displaced, the position of the limiting structure 60 connecting the two supporting portions 55 will also change, for example, when the width of the space between two adjacent supporting portions 55 becomes larger gradually, the limiting structure 60 will be able to define the maximum space between the two adjacent supporting portions, that is, the space between two adjacent supporting portions 55 cannot be infinitely larger, and when the space between the two adjacent supporting portions is too large, the supporting effect on the flexible display screen 10 in the stretched state will be weakened. Therefore, the embodiment of the present application defines the interval between the slidable supporting portions 53 by introducing the limiting structure 60 connecting the adjacent two supporting portions 55, 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 application may limit the maximum interval between two adjacent supporting portions 55, but may 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 still perform a better supporting function on the flexible display screen 10.
Referring to fig. 10 in combination with fig. 8 and 9, fig. 10 is a schematic connection diagram of the limiting structure 60 and the supporting portion 55, in an alternative embodiment of the present application, the limiting structure 60 includes a sliding rod 66 and first protruding portions 61 located on a surface of the supporting portion 55 facing the sliding rail 40, and the same sliding rod 66 is slidably connected with the first protruding portions 61 corresponding to two adjacent supporting portions 55.
Specifically, the present application introduces the slide bar 66 and the first protruding portion 61 on the slidable supporting portion 53 as the limiting structure 60, where the slide bar 66 and the first protruding portion 61 are both located on a side of the slidable supporting portion 53 facing away from the flexible display screen 10, and the slide bar 66 is slidably connected to the first protruding portion 61 on the two adjacent supporting portions 55, respectively. The slide bar 66 will be able to move relative to the first boss 61 when a relative displacement occurs between two adjacent support portions 55, i.e. when the spacing between two adjacent support portions 55 changes. When the flexible display screen 10 is stretched, since the maximum distance between the first protrusions 61 fixed on the adjacent two supporting portions 55 is fixed, when the relative positional relationship of the adjacent two first protrusions 61 reaches the maximum distance, the distance between the corresponding two supporting portions 55 cannot be further increased, which is equivalent to limiting the maximum distance between the adjacent two supporting portions 55, so that the gap between the two supporting portions is prevented from being too large to effectively support the flexible display screen 10. In addition, since the slide bar 66 itself has a certain rigidity, the length thereof does not change with the movement of the slidable support portion 53, the distance between the two first protruding portions 61 connected thereto can be defined in cooperation with the first protruding portions 61, and thus the width of the interval between the adjacent two support portions 55 can be precisely defined.
Alternatively, referring to fig. 10, the first protruding portion 61 is embodied as an elongated protruding structure on a side of the slidable supporting portion 53 facing away from the flexible display screen 10, and the extending direction of the first protruding portion 61 is the same as the extending direction of the corresponding supporting portion 55. Optionally, 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 that a space can be reserved for the movement of the supporting rod, even if two adjacent supporting portions 55 contact each other in the contracted state, a space for accommodating the sliding rod 66 is still provided 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 be still ensured.
Alternatively, a slide groove is provided in a side surface of the first boss 61, i.e., a side surface of the first boss 61 facing the other first boss 61 adjacent thereto, in which one end of the slide bar 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 61. When the display device is contracted or stretched, the two ends of the same slide bar 66 are respectively displaced in the two sliding grooves, so that the included angle between the slide bar 66 and the corresponding supporting portion 55 is changed, for example, in a contracted state, the included angle between the slide bar 66 and the supporting portion 55 is the smallest; in the stretched state, the angle between the slide bar 66 and the support 55 is at a maximum, which may be embodied for example as 90 °.
Alternatively, in the embodiment of the present application, the first protruding portion 61 and the sliding rod 66 may be disposed on each of the first fixed supporting portion 51, the second fixed supporting portion 52 and the slidable supporting portion 53, so that the distance between any two adjacent supporting portions 55 may 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 supporting portion 55 are the same.
With continued reference to fig. 8-10, in an alternative embodiment of the present application, the flexible display screen 10 includes a stretched state and a contracted state, and each slide bar 66 extends in the same direction or in parallel in the same stretched state or in the same contracted state, with equal spacing between any two adjacent support portions 55.
Specifically, the embodiment of the present application will be described taking a rectangular shape as an orthographic projection of the slide bar 66 on the plane of the support portion 55. When the interval between the adjacent two support parts 55 is changed, the extending direction of the slide bar 66 connecting the adjacent two support parts 55 is also changed, and when the interval between the adjacent two support parts 55 reaches the maximum interval, the extending direction of the slide bar 66 is changed to the first direction D1. The present application defines that the extending directions of the sliding bars 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 equal, that is, the slidable supporting portions 53 are uniformly arranged in both the shrinking state and the stretching state, thereby being capable of uniformly supporting the flexible display screen 10, having better supporting effect on the flexible display screen 10, and avoiding the situation of poor local supporting effect.
Fig. 11 is a schematic view showing another structure in a stretched state when the limiting structure 60 is introduced into the display device, fig. 12 is a schematic view showing another structure in a contracted state when the limiting structure 60 is introduced into the display device, and fig. 13 is a schematic view showing another connection between the limiting structure 60 and the supporting portion 55. This embodiment shows another version of the limit structure 60 in a display device.
Referring to fig. 11 to 13, in an alternative embodiment of the present application, the limiting structure 60 includes an elastic member 69 and a first protruding portion 61 located on a surface of the supporting portion 55 facing the sliding rail 40, and two ends of the same elastic member 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 application is embodied by the elastic member 69 and the first protruding portion 61, when the flexible screen is in the contracted state, the interval between the adjacent two supporting portions 55 is the smallest, 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 there is a limit value for the deformation amount of the elastic member 69, and when the elastic member 69 stretches to such an extent that it cannot be deformed further, the specific space between the adjacent two support 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 the adjacent two supporting portions 55 can be defined by the elastic member 69 as well, so that the excessive interval between the adjacent two supporting portions 55 is prevented from decreasing the supporting effect on the flexible display screen 10.
Referring to fig. 11 to 13, in an alternative embodiment of the present application, the flexible display screen 10 includes a stretched state and a contracted state, and in the same stretched state or the same contracted state, the deformation amount of each elastic member 69 is the same, and the interval between any two adjacent supporting portions 55 is equal.
Specifically, when the deformation amounts of the elastic members 69 are the same in the same stretching state or the same shrinking state, the same interval between any two supporting portions 55 connected with the elastic members 69 can be ensured, so that the slidable supporting portions 53 are arranged at equal intervals, that is, the slidable supporting portions 53 are uniformly arranged, and thus, the uniformly arranged slidable supporting portions 53 can provide uniform supporting force for the flexible display screen 10, the problem that the supporting force is insufficient at the local position of the flexible display screen 10 is avoided, and the supporting reliability and the fixing reliability of the flexible display screen 10 in the display device are improved.
Alternatively, the elastic member 69 mentioned in the embodiment of the present application is a spring.
Alternatively, referring to fig. 13, one end of the elastic member 69 is fixed to the side of the first protrusion 61, that is, the side of the first protrusion 61 facing the other first protrusion 61 adjacent thereto, and the other end is fixed to the side of the other first protrusion 61 adjacent to the first protrusion 61, and when the display device is contracted or stretched, the elastic member 69 is deformed such that the distance between the adjacent two supporting portions 55 is changed.
Alternatively, referring to fig. 13, the first protruding portion 61 is embodied as an elongated protruding structure on a side of the supporting portion 55 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 supporting portion 55. Optionally, 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 that a space can be reserved for the movement of the elastic member 69, even if two adjacent supporting portions 55 contact each other in the contracted state, a space can be accommodated between two adjacent first protruding portions 61, 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 still ensured.

Referring to fig. 14 and 15, in an alternative embodiment of the present application, the sliding rail 40 includes a first sliding rail structure 41 corresponding to the first fixed supporting portion 51, and the display device further includes a rotating portion 80, where 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 application includes the first slide rail structure 41 corresponding to the first fixed supporting portion 51, and the first slide rail structure 41 can be regarded as the slide rail 40 closest to the housing 21 than other slide rail 40 structures. Alternatively, the first sliding 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 application, the rotating part 80 slidingly connected with the first sliding rail structure 41 is introduced into the display device, and the rotating part 80 can drive the first sliding rail structure 41 to displace along the first direction D1 when rotating. For example, in the contracted state, the sliding portion 44 is embodied as a structure as shown in fig. 14, the extending direction of which intersects the first direction D1; during stretching, the rotating portion 80 rotates, and the first slide rail structure 41 moves away from the housing 21 along with the rotation of the rotating portion 80, so that the corresponding slidable support portion 53 is driven to move away from the housing 21. When the rotation portion 80 rotates to the extending direction D1, the supporting range of the supporting plate is further enlarged, so that the display area of the flexible display screen 10 is further enlarged.
Fig. 16 is a schematic view of the sliding rail 40 and the supporting portion 55 according to the embodiment of the present application, referring to fig. 5, 7 and 16, in an alternative embodiment of the present application, the sliding rail 40 includes a plurality of telescopic sliding portions 44 connected to each other, and the telescopic sliding portions 44 include sliding grooves 42 disposed towards the supporting portion 55; the side of the support 55 facing the slide rail 40 includes a second protrusion 59, the second protrusion 59 being located in the slide slot 42.
Specifically, in the embodiment of the present application, 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 may be a sliding connection, that is, two adjacent telescopic sliding portions 44 may be relatively displaced, so as to change the total length of the integral sliding groove 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 present embodiment includes a sliding groove 42 disposed towards the supporting portion 55, and a side of the supporting portion 55 facing the sliding rail 40 includes a second protruding portion, where the second protruding portion is disposed in the sliding groove 42 and is slidable in the sliding groove 42, so as to drive the slidable supporting portion 53 to slide. The supporting portion 55 is matched with the sliding groove 42 through the second protruding portion 59, so that falling-off of the supporting portion 55 and the sliding rail 40 is avoided, and stretching reliability of the display device in a stretching process and shrinking reliability of the display device in a shrinking process are improved.
Fig. 17 is a schematic structural diagram of the sliding rail 40 in a contracted state according to an embodiment of the present application, and fig. 18 is a schematic structural diagram of the sliding rail 40 in a stretched state according to an embodiment of the present application, in which the sliding rail 40 is illustrated as a sleeve structure.
Referring to fig. 17 and 18, in an alternative embodiment of the present application, the retractable sliding portion 44 is in a retractable sleeve structure, and in a 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 nested in the second sliding portion 46.
In particular, when the telescopic sliding portion 44 in the slide rail 40 is embodied as a telescopic sleeve structure, the length variation of the slide rail 40 is made more flexible. In any two adjacent telescopic sliding portions 44, the size of the first sliding portion 45 is smaller than that of the second sliding portion 46, at least part of the first sliding portion 45 is nested inside the second sliding portion 46, and the length of the sliding rail 40 can be changed by changing the relative position relationship of the first sliding portion 45 and the second sliding portion 46, for example, when most of the area of the first sliding portion 45 is nested in the second sliding portion 46, the length of the corresponding sliding rail 40 will be reduced; when most of the area of the first sliding portion 45 moves beyond the second sliding portion 46, the length of the corresponding sliding rail 40 will increase, so that the length of the sliding rail 40 can be flexibly controlled by controlling the relative positional 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 application, the height of the second protrusion/59 in the chute of the second sliding portion 46 is greater than the height of the second protrusion 59 in the chute of the first sliding portion 45.
When the sliding groove of the embodiment of the present application is formed by using the sleeve structure, since the size of the first sliding portion 45 is smaller than that of the second sliding portion 46 in the adjacent two telescopic sliding portions 44, 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, and the height of the second protruding portion located in the sliding groove of the second sliding portion 46 is set to be greater than that of the second protruding portion located in the sliding groove of the first sliding portion 45, so that the surfaces of the slidable supporting portions 53 corresponding to the first sliding portion 45 and the second sliding portion 46 facing the flexible display screen 10 are located on the same plane, 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 application, referring to fig. 1 to 5, the surfaces of the supporting portions 55 facing away from the sliding rail 40 are located on the same plane.
Specifically, the surface of the supporting portion 55 facing away from the sliding rail 40 is disposed on the same plane, so that the supporting portion 55 can provide a flat supporting surface for the flexible display screen 10, which is beneficial to improving the supporting effect on the flexible display screen 10. When the sliding rail 40 with the sleeve structure is adopted, the second protruding portion connected with the supporting portion 55 may be designed differently, so that the surface of the supporting portion 55 facing away from the sliding rail 40 is located on the same plane. Of course, in some other embodiments of the application, the thickness of the supporting portion 55 may be designed differently so that the surface of the supporting portion 55 facing away from the sliding rail 40 is located on the same plane, for example, the thickness of the supporting portion 55 corresponding to the second sliding portion 46 is designed to be larger than the thickness of the supporting 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 present application can also make up for the difference in height by simultaneously differentially designing the height of the first protruding portion connected to the supporting portion 55 and the thickness of the supporting portion 55, so that the surface of the supporting portion 55 facing away from the sliding rail 40 is located on the same plane.
In an alternative embodiment of the present application, please refer to fig. 1 and 4, an adsorption layer 90 is disposed on a side of the flexible display screen 10 facing the supporting structure 50, and the adsorption layer 90 is adsorbed to the supporting portion 55 when the distance between the second fixed supporting portion 52 and the housing 21 is fixed; when the second fixed supporting portion 52 is displaced relative to the housing 21, the adsorbing layer 90 is separated from the supporting portion 55.
Referring to fig. 1, in the embodiment of the present application, an adsorption layer 90 is introduced on the surface of the flexible display screen 10 facing the supporting structure 50, the adsorption layer 90 is fixed to the surface of the flexible display screen facing the supporting structure 50, and when the flexible display screen 10 is stretched, the adsorption layer 90 is stretched accordingly; when the flexible display 10 is contracted, the adsorption layer 90 is contracted accordingly. Optionally, the absorbent layer 90 is coated over the entire surface of the flexible display 10 facing the support structure 50. When the flexible display screen 10 is contracted or stretched to a certain size for displaying a picture, and is not contracted or stretched temporarily (i.e. the distance between the second fixed supporting portion 52 and the housing 21 is fixed), the adsorbing layer 90 and the supporting portion 55 adsorb, so that the flexible display screen 10 is fixed on the surface of the supporting portion 55, which is away from the sliding rail 40, which is beneficial to improving the fixing reliability of the flexible display screen 10 in the display process. When the flexible display screen 10 is in a moving state relative to the housing 21 (i.e., the second fixed supporting portion 52 is displaced relative to the housing 21, i.e., the second end portion 12 of the flexible display screen 10 is moved relative to the housing 21), the adsorption force between the adsorption layer 90 and the supporting portion 55 is eliminated, so as to realize smooth stretching or shrinking of the flexible display screen 10.
In an alternative embodiment of the present application, the adsorption layer 90 is a magnetic layer, and the support portion 55 includes a magnetic material; the adsorption layer 90 generates adsorption force under the control of an electric signal.
When the flexible display screen 10 and the supporting part 55 need to be fixed, the adsorption layer 90 can be controlled by an electric signal to generate adsorption force; when the flexible display 10 is required to be stretched or contracted, the adsorption force on the adsorption layer 90 can be removed by removing the electric signal, so that the support portion 55 and the flexible layer are not adsorbed.
In summary, the display device provided by the application at least realizes the following beneficial effects:
the display device provided by the application is provided with the sliding rail and the supporting structure connected with the sliding rail, wherein the supporting structure comprises the first fixed supporting part, the second fixed supporting part and a plurality of slidable supporting parts positioned between the first fixed supporting part and the second fixed supporting part, the slidable supporting parts can slide on the sliding 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 supporting part, and when the second fixed supporting part displaces relative to the shell, the slidable supporting parts slide on the sliding rail to drive the flexible display screen to shrink or stretch. When the flexible display screen is contracted, at least part of the flexible display screen is wound on the scroll so as to reduce the size of the display device and enable the display device to be 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 meanwhile has large-size display requirements. Particularly, the support part is introduced to one side of the sliding rail at the part of the flexible display screen, which is not wound on the winding shaft, and the support part plays a role in supporting the flexible display screen in a stretched state when the flexible display screen is stretched, so that the problems of deformation and the like can not occur even if the flexible display screen is pressed, the support reliability and the fixing reliability of the flexible display screen in the stretched state are greatly improved, and the problem of abnormal display caused by deformation possibly occurring when the flexible display screen is supported unreliably is effectively solved.
