Detailed Description
In the related art, in order to satisfy the foldable application, each functional film layer inside the flexible screen may be made of a flexible material to reduce the rigidity of the flexible screen and improve the flexibility thereof so as to facilitate folding. The backlight side of the flexible screen may be provided with a support member having mechanical strength that can form a support for the flexible screen. In addition, the support piece can drive the flexible screen to rotate under the action of external force, so that the folding and flattening functions of the flexible screen are realized.
However, when the flexible screen is in a folded state, the bending part of the flexible screen is deformed under the stress effect, and the deformation recovery capacity of each functional film layer in the flexible screen is limited, so that when the flexible screen is in a flattened state, folds appear on the bending part of the flexible screen, the display effect of the display device is affected, and the visual experience of a user is reduced.
In view of the above technical problems, embodiments of the present invention provide a foldable supporting device and a display device, where the foldable supporting device is applied to a flexible screen, and the foldable supporting device includes at least one bending supporting portion and at least two plane supporting portions, and the bending supporting portion is connected between two adjacent plane supporting portions to form a support for the flexible screen. The bending support parts comprise a first bending support piece and a second bending support piece, and the first bending support piece and the second bending support piece are respectively in one-to-one corresponding rotary connection with the two adjacent plane support parts. Through set up drive assembly in collapsible strutting arrangement, drive assembly drive kink supporting part motion, the bending of kink supporting part supports in the district of buckling of flexible screen, and the direction of buckling face and the direction of buckling of the crease of flexible screen are opposite to correct the crease, alleviate the crease on the flexible screen, in order to promote this flexible screen, and have the display effect and the user's visual experience of the display device of flexible screen.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment of the invention provides a display device which can be a mobile or fixed terminal with a foldable supporting device 100, such as electronic paper, a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, an ultra-personal computer, a navigator and the like.
As shown in fig. 1 and 2, the display device may include a housing 90, a foldable support device 100, and a flexible screen 80, the flexible screen 80 being fixed to the foldable support device 100, the foldable support device 100 being located at a backlight side of the flexible screen 80. The foldable support device 100 may drive the flexible screen 80 to fold and support the flexible screen 80. The flexible screen 80 and the foldable support device 100 are both located in the housing 90.
The flexible screen 80 includes a bending zone 83 and two planar zones, a first planar zone 81 and a second planar zone 82, respectively, the first planar zone 81 and the second planar zone 82 being connected by the bending zone 83. Wherein the first planar area 81 and the second planar area 82 of the flexible screen 80 may be planar, and the inflection area 83 of the flexible screen 80 may be inflection.
As shown in fig. 2, 3, and 4, the position states of flexible screen 80 may include a flattened state and a folded state. The flattened and folded states of the flexible screen 80 are also those of the display device and the foldable support device 100.
As shown in FIG. 2, the flattened state refers to a state in which portions of flexible screen 80 are substantially coplanar. At this time, the first plane area 81, the second plane area 82 and the inflection area 83 are substantially on the same plane, and an included angle between the first plane area 81 and the second plane area 82 is substantially 180 degrees. In the flattened state, the display area of the flexible screen 80 is large to ensure a good user experience.
As shown in fig. 3 and 4, the folded state means that the folded region 83 of the flexible screen 80 is folded, and both ends of the folded region 83 connected to the first and second planar regions 81 and 82, respectively, are folded and overlapped with each other in the thickness direction of the flexible screen 80. At this time, the first and second flat areas 81, 82 overlap each other in the thickness direction of the flexible screen 80, and the angle between the first and second flat areas 81, 82 is approximately 0 degrees. In the folded state, the flexible screen 80 and the display device having the flexible screen 80 are small in size, and the storage and carrying of the display device are facilitated.
It will be appreciated that the flexible screen 80 may be in any of a folded state, a flattened state, and a state therebetween when the display device is in use by a user, and this embodiment is not limited thereto.
After the foldable support device 100 is connected with the flexible screen 80, a user applies a force to the foldable support device 100 to realize that the foldable support device 100 drives the flexible screen 80 to switch between the flattened state and the folded state.
As shown in fig. 2, the foldable support device 100 includes a first surface 100a and a second surface 100b disposed opposite to each other, the first surface 100a being configured to engage the flexible screen 80 to support the flexible screen 80. The second surface 100b is the other side facing away from the first surface 100 a.
As shown in fig. 3, the display device may be an inward folding display device, that is, when the flexible screen 80 is in a folded state, the folded flexible screen 80 is located at the inner side of the foldable support device 100, and the foldable support device 100 may protect the flexible screen 80. At this time, the first planar area 81 and the second planar area 82 are disposed opposite to each other.
As shown in fig. 4, when the flexible screen 80 is folded, the bending area 83 of the flexible screen 80 is bent to deform. The deformed portion of the flexible screen 80 is concentrated in the middle region C (the portion in the dashed box C in fig. 4) of the inflection region 83, and the transition region D (the portion in the dashed box D in fig. 4) between the inflection region 83 and the planar region.
The flexible screen 80 is repeatedly folded and flattened in use, and the deformation recovery capability of each functional film layer in the flexible screen 80 is limited, so that deformation on the flexible screen 80 cannot be recovered to generate crease lines when the flexible screen 80 is in a flattened state, the display effect of the display device is affected, and the visual experience of a user is reduced.
As shown in fig. 4 and 5, the folds produced by the flexible screen 80 include a middle fold 841 located in the middle region C, and a transition fold 842 located in the transition region D, and the folding direction of each fold corresponds to the folding direction of the flexible screen 80 in the folded state. The intermediate crease 841 is folded in a direction towards the foldable support device 100 and the intermediate crease 842 is folded in a direction away from the foldable support device 100.
When the flexible screen 80 is folded, the flexible screen in the middle area C has a larger bending angle and bending range than the flexible screen in the transition area D, and therefore, the middle crease 841 has a larger influence on the display effect of the display device than the transition crease 842. The embodiment of the application mainly aims at the middle crease 841 and has a certain correction effect on the transition crease 842.
It should be noted that the embodiments of the present application are mainly described with respect to a flexible screen having a bending region and two planar regions. In some examples, the flexible screen may include more planar regions and inflection regions, with adjacent planar regions being connected by one inflection region. The foldable support device 100 of the embodiment of the present application can be applied to correct the intermediate crease 841 as long as the intermediate crease 841 is present in the flexible screen as a result of the inner folding in the embodiment of the present application.
The position state of the foldable support device 100 may also include a flattened adjustment state. As shown in fig. 6 and 7, the flattening adjustment state refers to that, on the basis of the flattening state of the foldable supporting device 100, the foldable supporting device 100 drives the bending region 83 of the flexible screen 80 to move in a direction away from the foldable supporting device 100, so that the bending region 83 of the flexible screen 80 bends in a direction away from the foldable supporting device 100, and is opposite to the bending direction of the middle crease 841, thereby correcting the middle crease 841, improving the flatness of the flexible screen 80, and improving the display effect of the display device and the visual experience of the user.
The foldable support device 100 provided in this embodiment will be described in detail with reference to the accompanying drawings.
It should be noted that, the first extending direction of the foldable supporting device 100 is the X direction in fig. 1, and the second extending direction of the foldable supporting device 100 is the Y direction in fig. 1; the first extending direction X and the second extending direction Y may be perpendicular and parallel to the first surface 100 a.
The display device may include a mounting portion, which may be a mounting structure such as a mounting plate, a mounting frame, or a mounting groove, and the specific type of the mounting structure is not limited in this embodiment. Part of the components of the collapsible supporting device 100 may be assembled on the mounting structure. The mounting structure may be assembled with the flexible screen 80 or the housing 90 when the collapsible supporting device 100 is assembled. Furthermore, the mounting portion may also be at least part of the flexible screen 80 or the housing 90, such that part of the components of the foldable support device 100 may be directly assembled to the flexible screen 80 or the housing 90. The embodiment of the application does not limit the specific setting mode of the installation part, and a user can select according to the actual setting mode.
The present embodiment will be described taking the mounting portion as the case 90 as an example.
The foldable supporting device 100 includes two planar supporting portions and a bending supporting portion, and the two planar supporting portions are in one-to-one correspondence with the two planar areas. When the display device is in a flattened state, the two plane supporting parts are arranged at intervals along the first extending direction X of the foldable supporting device 100, and the plane supporting parts are used for supporting the plane area and driving the plane area to rotate so as to realize folding. The bending support portion is used for supporting the bending region 83.
It will be appreciated that the planar support portions and the planar regions are disposed in one-to-one correspondence, and the bending support portions and the bending regions 83 are disposed in one-to-one correspondence, so that if the number of the planar regions and the bending regions 83 is greater, the number of the planar support portions and the bending support portions is correspondingly increased.
Wherein the planar support may be mounted on the housing 90 to fix the planar support. Thus, the user rotates the plane supporting part by operating the housing 90.
The bending support parts are connected between the two plane support parts, namely, the bending support parts are positioned between the two plane support parts, and the bending support parts are respectively connected with the plane support parts. Specifically, as shown in fig. 2, the bending support part includes a first bending support 21 and a second bending support 22, and the two plane support parts include a first plane support 11 and a second plane support 12. When the display device is in a flattened state, the first bending support piece 21 and the second bending support piece 22 are arranged along the first extending direction X, and the first bending support piece 21 is rotationally connected with the first plane support piece 11, and the second bending support piece 22 is rotationally connected with the second plane support piece 12.
Thus, as shown in fig. 3 and 4, when the display device is in the folded state, the included angle between the first bending support member 21 and the first plane support member 11, and the included angle between the second bending support member 22 and the second plane support member 12 may be equal to the bending angle of the flexible screen 80 in the transition region D, so as to reduce the stress generated on the flexible screen 80 in the transition region D.
In this embodiment, as shown in fig. 2, 7 and 8, the foldable supporting device 100 further includes a driving assembly, and the driving assembly is used for driving the bending supporting portion to move in a direction away from the foldable supporting device 100, and the bending supporting portion drives the bending region 83 of the flexible screen 80 to move in a direction away from the foldable supporting device 100, so as to correct the crease, and improve the display effect of the display device.
The driving assembly at least comprises a first driving piece 30 and a second driving piece 40, wherein the first driving piece 30 is connected with the first bending support piece 21, and the second driving piece 40 is connected with the second bending support piece 22.
In this way, the first driving member 30 drives the end portion of the first bending support member 21 near the second bending support member 22 to move in the direction near the first surface 100a, and the second driving member 40 drives the end portion of the second bending support member 22 near the first bending support member 21 to move in the direction near the first surface 100a, so that the surface of the first bending support member 21 near the first surface 100a and the surface of the second bending support member 22 near the first surface 100a form a bending surface 23 together (in fig. 8), and the bending surface 23 is used to abut against the flexible screen 80 located in the bending region 83, so that the flexible screen 80 in the bending region 83 assumes the same bending state as the bending surface 23. At this time, the flat adjustment state of the foldable supporting device 100 is formed, the bending surface 23 is bent towards the direction of the first surface 100a, that is, the bending surface 23 is bent towards the direction of the flexible screen 80, so that the bending region 83 of the flexible screen 80 is bent towards the direction away from the foldable supporting device 100, and the bending direction is opposite to the bending direction of the middle crease 841, so as to correct the middle crease 841 and improve the display effect of the display device.
Wherein, as shown in fig. 8, the bending surface 23 is formed by the surfaces of the first bending support 21 and the second bending support 22 facing the flexible screen 80 side. The face of the first bending support 21 facing the flexible screen 80 side and the face of the second bending support 22 facing the flexible screen 80 side may be joined together to form the complete bending face 23, or a space may be provided between the face of the first bending support 21 facing the flexible screen 80 side and the face of the second bending support 22 facing the flexible screen 80 side to form the broken bending face 23.
It should be noted that the number of the first driving members 30 may be at least one. When the number of the first driving pieces 30 is 1, the first driving pieces 30 may be located at one end of the first bending support 21 in the second extension direction Y. When the number of the first driving pieces 30 is 2 (in fig. 1), the first driving pieces 30 may be respectively located at both ends of the first bending support 21 in the second extension direction Y. In this way, the first driving member 30 is located at the end of the first bending support member 21, so that the layout effect of the first driving member 30 on other structures can be reduced.
The number of the second driving members 40 may be at least one, and the arrangement manner thereof may be the same as that of the first driving member 30, and the principle is similar to that of the first driving member 30, and will not be repeated.
The structures of the first driving member 30 and the second driving member 40 may be identical, or the structures of the first driving member 30 and the second driving member 40 may be different. In the embodiment in which the first driving member 30 and the second driving member 40 have the same structure, each of the first driving member 30 and the second driving member 40 includes a driving portion and a driven portion, the driven portion is rotatably connected to the mounting portion, and the mounting portion has a positioning and supporting function on the driven portion.
The driving part and the driven part are mutually linked, and the driving part drives the driven part to move so that the driven part drives the bending support part to move. As shown in fig. 3, the driving portion of the first driver 30 is a first driving portion 31, the driven portion of the first driver 30 is a first driven portion 32, the driving portion of the second driver 40 is a second driving portion 41, and the driven portion of the second driver 40 is a second driven portion 42.
As shown in fig. 8 and 9, an end of the first bending support 21 near the second bending support 22 is a first movable end 211 of the first bending support 21; the other end of the first bending support 21 away from the second bending support 22 is a first connection end 212 of the first bending support 21, and the first connection end 212 is an end rotationally connected with the first plane support 11. When the first bending support 21 rotates around the first connection end 212, the first movable end 211 may reciprocate in the thickness direction of the display device to move the flexible screen 80.
The first movable end 211 is movably connected to the first driven portion 32, and the first driving portion 31 is configured to drive the first driven portion 32 to move in a direction approaching the first surface 100a, so that the first movable end 211 moves in a direction approaching the first surface 100 a.
The end of the second bending support 22 near the first bending support 21 is a second movable end 221 of the second bending support 22, the other end of the second bending support 22 far away from the first bending support 21 is a second connecting end 222 of the second bending support 22, and the second connecting end 222 is an end rotationally connected with the second plane support 12. When the second bending support 22 rotates around the second connecting end 222, the second movable end 221 can reciprocate along the thickness direction of the display device to drive the flexible screen 80 to move.
The second movable end 221 is movably connected to the second driven portion 42, and the second driving portion 41 is configured to drive the second driven portion 42 to move in a direction approaching the first surface 100a, so that the second movable end 221 moves in a direction approaching the first surface 100 a.
As shown in fig. 6 and 7, when the foldable support device 100 is in the flattened and adjusted state, both the first movable end 211 and the second movable end 221 move in a direction approaching the first surface 100 a. The first movable end 211 and the second movable end 221 drive the flexible screen 80 of the bending region 83 to move towards the direction away from the foldable supporting device 100, so as to correct the middle crease 841 and improve the display effect of the display device.
It will be appreciated that when the first movable end 211 and the second movable end 221 are moved in a direction approaching the first surface 100a, the first connecting end 212 and the second connecting end 222 will move in a direction approaching the second surface 100b, thereby correcting the transition crease 842 and further improving the display effect of the display device.
As shown in fig. 6, the angle between the surface of the first bending support 21 near the first surface 100a and the horizontal plane is θ, and the angle of θ may be less than or equal to 5 degrees. When the angle θ is greater than 5 degrees, the force applied to the flexible screen 80 by the first bending support 21 is excessive, which may cause the connection portion between the flexible screen 80 and the foldable support device 100 to be detached. Wherein the plane parallel to the plane in which flexible screen 80 is in the flattened state is a horizontal plane. Wherein, the included angle θ may be 4 degrees or less. For example, the included angle θ may be 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, or the like, which is not limited in the embodiment of the present application.
The angle between the surface of the second bending support 22 near the first surface 100a and the horizontal plane may be less than or equal to 5 degrees. The principle is similar to the included angle theta, and the description is omitted.
In some examples, the angle between the surface of the first bending support 21 near the first surface 100a and the horizontal plane is equal to the angle between the surface of the second bending support 22 near the first surface 100a and the horizontal plane. As such, the flexible panel 80 is relatively uniformly forced by the first bending support 21 and the second bending support 22.
In some embodiments, in the same driving member, a side of the driving portion, which is close to the first surface 100a, has a driving surface, and an end of the driven portion, which is far away from the first surface 100a, abuts against the driving surface. Thus, the driving part can drive the driven part to move through the driving surface, and the driving surface forms a support for the driven part.
In some examples, the driving surface is provided with a limiting groove 301, as shown in fig. 10, the driving surface of the first driving portion 31 may be provided with the limiting groove 301, or the driving surface of the second driving portion 41 may be provided with the limiting groove 301. In this way, the end of the driven portion away from the first surface 100a abuts against the inner wall surface of the limit groove 301, and the limit groove 301 can limit the movement of the driven portion along the second extending direction Y. The limiting groove 301 extends in the direction from the first bending support 21 to the second bending support 22, and thus, the driven portion can reciprocate in the first extending direction X through the limiting groove 301.
As shown in fig. 8 and 9, taking the first driving element 30 as an example, the driving surface of the first driving portion 31 is a first driving surface 33, the first driving surface 33 is an inclined surface, the surface of the first driven portion 32 near the first driving portion 31 is an inclined surface adapted to the first driving surface 33, and the end of the first driving surface 33 near the second bending support 22 is closer to the first surface 100a than the end of the first driving surface 33 far from the second bending support 22.
In this way, when the flexible screen 80 needs to be crease-corrected, the first driving portion 31 moves towards the direction away from the second driving portion 41, the first driven portion 32 receives the force of the first driving portion 31 towards the first surface 100a, so that the first driven portion 32 moves towards the direction of the first surface 100a, and the first driven portion 32 drives the first bending support 21 to move, so that the bending region 83 of the flexible screen 80 moves towards the direction away from the foldable support device 100, and the middle crease 841 is corrected.
One end of the first driven part 32 far away from the second driven part 42 is rotatably connected with the mounting part, so that one end of the first driven part 32 near the second driven part 42 reciprocates along the thickness direction of the display device under the action of the first driving part 31, thereby driving the first movable end 211 of the first bending support piece 21 to move so as to drive the flexible screen 80 to move.
The end of the driving surface of the second driving member 40 that is closer to the first bending support 21 is closer to the first surface 100a than the end of the driving surface of the second driving member 40 that is farther from the first bending support 21. The principle is similar to that of the first driving member 30 and will not be described again. In this way, the first driving portion 31 and the second driving portion 41 move in the direction away from each other, and the flat-out adjustment state of the foldable support device 100 is formed, so that the crease of the flexible screen 80 is corrected.
After the crease correction of the flexible screen 80 is finished, the first driving portion 31 moves towards the second driving portion 41, the first bending support piece 21 receives the pressing force of the flexible screen 80, so that the first movable end 211 of the first bending support piece 21 moves towards the second surface 100b, and one end, close to the second driven portion 42, of the first driven portion 32 is driven to move towards the second surface 100b, and therefore part of the flexible screen 80 returns to the flattened state.
The principle of the second driving part 41 is similar to that of the first driving part 31, and will not be described again. In this way, the first driving portion 31 and the second driving portion 41 move in the direction approaching each other, and the flat state of the foldable support device 100 is formed.
When it is desired to fold the flexible screen 80, both planar support portions are moved in a direction toward the first surface 100a so that the planar support portions are folded to form a folded state of the foldable support device 100.
In some examples, the drive surface is a obliquely disposed planar surface; alternatively, the driving surface is an arc surface disposed obliquely, and the driving surface is curved in a direction away from the first surface 100 a. In this way, the driving surface can be selected according to the requirement.
In some embodiments, the first driven portion 32 of the first driving member 30 is connected to the first movable end 211 of the first bending support 21 by a sliding assembly. The first driven portion 32 and the first bending support 21 slide with each other by a sliding assembly.
As shown in fig. 9, the sliding assembly between the first driven portion 32 and the first bending support 21 is a first sliding assembly 51. Specifically, the first sliding assembly 51 includes a first sliding slot 511 and a first sliding block 512, and the first sliding block 512 is slidably connected in the first sliding slot 511. Thus, the first slider 512 can slide in the extending direction of the length of the first slide groove 511.
In some examples, as shown in fig. 9, the first sliding groove 511 is disposed on the first driven portion 32, and the first slider 512 is disposed on the first movable end 211. In this way, when the first slider 512 slides along the extending direction of the length of the first sliding slot 511, the first movable end 211 is driven to slide along the extending direction of the length of the first sliding slot 511. The extending direction of the length of the first chute 511 is the first extending direction X.
When the display device is in the flattened state, the first slider 512 is located at an end of the first sliding groove 511 near the second movable end 221. When the display device is folded, the first slider 512 drives the first movable end 211 to slide along the first sliding groove 511, and the first slider 512 slides in a direction away from the second movable end 221. When the display device is in the folded state, the first slider 512 moves to an end of the first chute 511 away from the second movable end 221.
Illustratively, the first chute 511 is an arcuate slot, and the first chute 511 curves away from the first surface 100 a. In the unfolding or folding process of the display device, the movement track of the first movable end 211 is similar to the shape of the arc-shaped groove, and the sliding between the first sliding block 512 and the first sliding groove 511 is smooth.
In other examples, the first sliding groove 511 is disposed on the first movable end 211, and the first slider 512 is disposed on the first driven portion 32. The principle of the first sliding groove 511 is similar to that of the first sliding groove 511 disposed on the first driven portion 32, and the first sliding block 512 is disposed on the first movable end 211, which will not be described again.
In addition, the driven portion of the second driving member 40 is connected to the movable end of the second bending support member 22 through a second sliding assembly, and the second sliding assembly includes a second chute and a second slider. The second sliding chute is disposed on one of the second driven portion 42 and the second movable end 221; the second slider is disposed on the other of the second driven portion 42 and the second movable end 221. The principle is similar to that of the first slider assembly 51 and will not be described again.
Illustratively, the second runner is an arcuate slot that curves away from the first surface 100 a. The principle is similar to that of the first chute 511, and will not be described again.
As shown in fig. 3, when the display device is in the folded state, the first movable end 211 is located at an end of the first driven portion 32 away from the second driven portion 42, and the second movable end 221 is located at an end of the second driven portion 42 away from the first driven portion 32. A drop-like shape is formed between the first bending support 21 and the second bending support 22 such that the flexible screen 80 of the bending zone 83 forms a drop-like shape. In this way, the first planar area 81 and the second planar area 82 are tightly attached, so that foreign matters such as dust outside can be prevented from entering between the first planar area 81 and the second planar area 82, and abrasion is caused to the flexible screen 80 of the first planar area 81 and the second planar area 82.
In some embodiments, as shown in fig. 2, at least a portion of the surface of the first bending support 21 away from the first surface 100a is an inclined surface. For example, an end of the first bending support 21 near the second bending support 22 is inclined toward a direction approaching the first surface 100a as compared to an end of the first bending support 21 far from the second bending support 22. I.e. the portion near the first movable end 211 is arranged to be thin. In this way, during the folding process of the display device, the first movable end 211 is prevented from being too thick, which may cause interference to other structures in the display device during the movement thereof. In addition, the rest of the first bending support 21 may be provided thicker, the strength of the first bending support 21 is higher, and the supporting effect on the flexible screen 80 is better.
In other examples, the surface of the first bending support 21 on the side away from the first surface 100a is an inclined surface as a whole. It is further avoided that the first bending support 21 interferes with the rest of the structure in the display device during folding.
At least a portion of the surface of the second bending support 22 away from the first surface 100a is an inclined surface. The principle is similar to that of the first bending support 21 and will not be described again.
In some embodiments, as shown in fig. 1 and 8, the first driven portion 32 is coupled to the second driven portion 42 via a first rotating member 60. For example, the first rotating member 60 may be a pair of intermeshing gears. The first driven portion 32 and the second driven portion 42 may be moved synchronously by the first rotating member 60. In this way, the first driven portion 32 and the second driven portion 42 drive the first bending support 21 and the second bending support 22 to move synchronously, and the acting forces of the two bending supports on the flexible screen 80 are balanced.
In some embodiments, as further shown in fig. 1 and 9, the first planar support 11 and the second planar support 12 are connected by a connection assembly. Wherein the connection assembly comprises a first connection member 71 and a second connection member 72, the first connection member 71 is disposed on a side of the first planar support member 11 adjacent to the second planar support member 12, and the second connection member 72 is disposed on a side of the second planar support member 12 adjacent to the first planar support member 11. The first connection member 71 and the second connection member 72 are connected by a second rotation member 73. In some examples, the second rotating member 73 may be a pair of gears meshed with each other, the first plane supporting member 11 and the second plane supporting member 12 may move synchronously, the forces generated by the first plane supporting member 11 and the second plane supporting member 12 on the flexible screen 80 are balanced, and the structure of the pair of gears is simple. In other examples, the second rotating member 73 may be a hinge structure, and the control of the hinge structure is more precise.
As shown in fig. 7 and 8, the first bending support 21 may be rotatably connected to the first connection member 71 by the first rotation connection portion 21a, and the first connection member 71 is fixed to the first plane support 11, so that the first bending support 21 is indirectly rotatably connected to the first plane support 11.
The first plane supporting member 11 may be fixed on the housing 90, which is equivalent to that the first bending supporting member 21 is indirectly rotatably connected to the housing 90, so that the first bending supporting member 21 can be indirectly supported and fixed by the housing 90, thereby realizing the rotation of the first bending supporting member 21.
The second bending support 22 may be rotatably coupled to the second coupling member 72 by the second rotary coupling portion 22 a. The principle is similar to that of the first bending support 21 and will not be described again.
With continued reference to fig. 7 and 8, the first driven portion 32 may be rotatably coupled to the housing 90 through the third rotary coupling portion 32a such that the first driven portion 32 may be supported and fixed by the housing 90, thereby enabling rotation of the first driven portion 32.
The second driven portion 42 may be rotatably connected to the housing 90 through the fourth rotary connecting portion 42a, and the principle thereof is similar to that of the first driven portion 32, and will not be described again.

In this way, the first connecting member 71 and the second connecting member 72, and the first driven portion 32 and the second driven portion 42, relatively balance the forces applied to the flexible screen 80 at both sides of the broken line AA in fig. 1 during the mutual rotation.
In some embodiments, the first surface 100a has a flexible screen placement area thereon for corresponding to the flexible screen 80, the flexible screen placement area for securing and supporting the flexible screen 80.
As in fig. 1, a dashed box P shows a flexible screen placement area. It will be appreciated that the flexible screen placement area may also be of a greater or lesser extent than shown by the dashed box P.
At least part of the planar support and at least part of the bending support are located in the flexible screen placement area. In this way, both the planar areas and the inflection areas 83 of the flexible screen 80 can be supported by the support.
And a space is reserved between the flexible screen placement area and the driving assembly along the second extending direction Y. The drive assembly may be located outside of the flexible screen placement area. In this way, the driven part of the driving assembly can be prevented from rubbing or extruding the flexible screen 80 in the moving process, and damage to the flexible screen 80 can be avoided.
In some examples, as shown in fig. 1, there may be two first connectors 71, and the two first connectors 71 are located on both ends of the first plane support 11 in the second extension direction Y, respectively. Along the second extension direction Y, the first driving member 30 may be located between the first connection member 71 and the first bending support 21, and a space may be provided between the first driving member 30 and the first connection member 71.
