Referring to fig. 1 to 4, there may be two supporting members in the present embodiment, and at least two supporting members include a first supporting member 11 and a second supporting member 12. As an achievable embodiment, the first support 11 comprises a support portion 13 and a sliding portion 14, the support portion 13 of the first support 11 being rotatably connected with the second support 12. As another realizable embodiment, the first support 11 and the second support 12 each include a support portion 13 and a sliding portion 14, and the support portion 13 of the first support 11 and the support portion 13 of the second support 12 are rotatably connected.
In practical use, the number of the supporting members may be plural, for example, three, four or five. The multiple supporting pieces are also connected end to end in the direction of L1. The number of the supporting members is not limited in the present embodiment. When the support members are provided with the sliding portion 14 and the support portion 13, two adjacent support members may be rotatably connected through the respective support portion 13, may also be rotatably connected through the respective sliding portion 14, and of course, may also be rotatably connected through the sliding portion 14 of one support member and the support portion 13 of the other support member, which is not limited in this embodiment.
Specifically, referring to fig. 11, at least one slide assembly 15 is provided between the slide portion 14 and the support portion 13. As an achievable embodiment, the slide assembly 15 includes a slide rail 152 provided on one of the slide portion 14 and the support portion 13, and the other of the slide portion 14 and the support portion 13 is reciprocally slidable in an extending direction of the slide rail 152. As an achievable embodiment, the slide assembly 15 includes a slide rail 152 provided on one of the slide portion 14 and the support portion 13, and a slide member 151 provided on the other of the slide portion 14 and the support portion 13, the slide member 151 being located on the slide rail 152 and reciprocally sliding in an extending direction of the slide rail 152. The extending direction of the sliding channel 152 is the length direction of the flexible display panel 20.
It should be noted that the slide rail 152 may be disposed on the entire supporting portion 13 or the sliding portion 14 along the direction L1, so as to reduce the sliding resistance of the sliding portion 14 and the supporting portion 13 during sliding, reduce the difficulty of the relative sliding between the two, and improve the operability of the display device 100. The sliding assemblies 15 may be provided in plurality, and the sliding assemblies 15 may be located on two opposite side edges of the support body 10 along the width direction L2 of the flexible display panel 20, so that when the sliding portion 14 slides relative to the support portion 13, the two side edges both have a sliding process in which the sliding assemblies 15 are used for supporting the sliding portion 14, and stability in the sliding process is improved.
Further, as shown in fig. 11, based on the fact that the display device 100 is used in a stretched state during sliding, it is necessary to ensure that the support portion 13 and the sliding portion 14 maintain the stretched position, i.e., that both remain relatively stationary during use by a user, thereby ensuring stability of use of the display device 100. To achieve the above object, a plurality of locking assemblies 16 are disposed between the sliding portion 14 and the supporting portion 13, and the plurality of locking assemblies 16 are disposed between the sliding portion 14 and the supporting portion 13 at intervals along the length direction of the flexible display panel 20. The locking assembly 16 includes a locking groove 161 disposed on one of the sliding portion 14 and the supporting portion 13, and a mounting groove 162, an elastic member 163, and a locking member 164 disposed on the other of the sliding portion 14 and the supporting portion 13, wherein the locking member 164 is mounted in the mounting groove 162 by the elastic member 163, and the locking member 164 is locked into or released from the locking groove 161 by the elastic member 163.
It should be noted that, a plurality of locking assemblies 16 are arranged at intervals between the sliding portion 14 and the supporting portion 13, during the sliding process of the sliding portion 14 on the supporting portion 13, when a certain relative sliding position between the sliding portion 14 and the supporting portion 13 needs to be locked, the locking member 164 is pushed by the elastic member 163 to pop out of the mounting groove 162, at this time, the elastic member 163 is in a free state, the locking member 164 is clamped into the locking groove 161, and the sliding portion 14 and the supporting portion 13 are relatively fixed. At this time, the sliding portion 14 is not subjected to a large external force, and the locking member 164 and the locking groove 161 are engaged with each other to keep the sliding portion 14 and the supporting portion 13 fixed relative to each other. When the other relative sliding position needs to be locked, the sliding part 14 can be pushed to slide, and the pushing force is greater than the relative clamping acting force between the locking piece 164 and the locking groove 161, so that the locking piece 164 exits from the locking groove 161 and retracts into the mounting groove 162, and the elastic piece 163 is in a compressed state. The locking member 164 slides between the adjacent locking grooves 161, and when encountering the next locking groove 161 during the sliding process, the locking member can be re-clamped in the locking groove 161, so as to form a locking state of the sliding portion 14 and the supporting portion 13 at another relative sliding position.
Further, based on the distribution of the flexible display panel 20 on both the first surface 10a and the second surface 10b, in order to ensure the integrity of the display viewed by the user, that is, the flexible display panel 20 on the first surface 10a displays one complete picture, the flexible display panel 20 on the second surface 10b displays another complete picture. The present embodiment is provided with a displacement sensor between the sliding portion 14 and the support portion 13, the displacement sensor being for measuring a sliding displacement of the sliding portion 14 relative to the support portion 13. The display device 100 includes a controller, and the displacement sensor and the driving circuit board of the flexible display panel 20 are electrically connected to the controller.
When the display device 100 is not stretched in a sliding manner, the flexible display panels 20 on the first surface 10a and the second surface 10b display a complete picture. When the display device 100 performs the slide-stretch operation, the flexible display panels 20 on the first surface 10a and the second surface 10b are transferred to each other. At this time, it is necessary to determine the displacement of the sliding part 14 sliding relative to the supporting part 13 according to the displacement sensor, and the displacement may also reflect the displacement of the flexible display panel 20 on the first surface 10a and the second surface 10b mutually transferred. The controller generates a picture adjustment signal according to the displacement signal, the driving circuit board of the flexible display panel 20 determines the sizes of the first display area and the second display area of the flexible display panel 20 according to the picture adjustment signal, and sends the display picture information corresponding to the first display area and the second display area respectively to ensure that the flexible display panel 20 on the first surface 10a is the first display area and the flexible display panel 20 on the second surface 10b is the second display area, and each display area respectively displays a complete picture.
As shown in fig. 8 to 10, when the sliding portion 14 and the supporting portion 13 are not slid, the length of the flexible display panel 20 on the first surface 10a is x1 (not shown in the figure), and the length of the flexible display panel 20 on the second surface 10b is x2 (not shown in the figure). When the sliding part 14 is slidably displaced by b relative to the supporting part 13 (as shown in fig. 10), it can be determined that the flexible display panel 20 with the length b on the second surface 10b moves to the first surface 10a, and only the flexible display panel 20 with the length a remains on the second surface 10b (as shown in fig. 8). The controller determines the picture adjustment signal according to the above displacement, that is, the flexible display panel 20 on the first surface 10a is a first display area, the length of the first display area is x1+ b, the flexible display panel 20 on the second surface 10b is a second display area, and the length of the second display area is x2-b, which is a. At the moment, the driving circuit board drives the area with the length of x1+ b to display the first picture, and the area with the length of x2-b to display the second picture, so that the first picture can be ensured to be displayed in the first display area, and the second picture is ensured to be displayed in the second display area, thereby ensuring the integrity of the displayed pictures and improving the use experience of users.
Specifically, the supporting portion 13 has a first receiving cavity therein, the first receiving cavity extends along the length direction of the flexible display panel 20, at least a portion of the sliding portion 14 is located in the first receiving cavity and slides back and forth along the extending direction of the first receiving cavity, and the end of the sliding portion 14 extends out of the first receiving cavity. It should be noted that, by disposing the sliding part 14 in the first accommodating cavity of the supporting part 13, the sliding process of the sliding part 14 can be limited and guided by the inner wall of the first accommodating cavity, and the sliding part 14 can be protected. Meanwhile, the first accommodating cavity can isolate the sliding part 14 and the flexible display panel 20, so that the sliding process of the sliding part 14 and the influence of the sliding assembly 15 used in the sliding process on the flexible display panel 20 are avoided, the supporting stability of the supporting part 13 on the flexible display panel 20 is improved, and the stability of a display picture on the flexible display panel 20 is ensured.
Referring to fig. 4, when the display device 100 is folded or stretched in a sliding manner, the flexible display panels 20 on the first surface 10a and the second surface 10b are displaced from each other, and the flexible display panels 20 located at the ends of the sliding portions 14 may be in sliding friction with the sliding portions 14, which may cause scratches on the flexible display panels 20. To avoid this, the end of the sliding part 14 of the present embodiment is provided with a rolling member 141, and the flexible display panel 20 is wrapped on the surface of the rolling member 141 and extends to the second surface 10b of the support body 10 while covering at least a part of the second surface 10 b. It should be noted that the rolling member 141 may be a pulley or a roller disposed at an end of the sliding portion 14, and the flexible display panel 20 is wrapped on a surface of the pulley or the roller. When the flexible display panel 20 moves, the rolling member 141 rotates to convert sliding friction between the two into rolling friction, so that damage to the flexible display panel 20 caused by friction is greatly reduced, the protection effect on the flexible display panel 20 is improved, the resistance to movement of the flexible display panel 20 can be reduced, and the operation difficulty of the display device 100 is reduced.
Further, during the folding process of the display device 100, there is also a mutual transfer process of the flexible display panels 20 on the first surface 10a and the second surface 10b, for example, referring to the folding state shown in fig. 5, the flexible display panels 20 near the rotational connection of the first support 11 and the second support 12 will be wrinkled and piled up at the rotational connection, and the long-time wrinkle piling up will reduce the strength of the flexible display panel 20, at this time, the flexible display panel 20 on the first surface 10a needs to be transferred to the second surface 10b to ensure that the flexible display panel 20 at the rotational connection is in a flat state. Alternatively, when the first support 11 and the second support 12 rotate in opposite directions of fig. 5, the flexible display panel 20 at the rotational joint is pulled by two ends of the first support 11 and the second support 12, so that the stress at the rotational joint is too high and the flexible display panel 20 at the second surface 10b needs to be transferred to the first surface 10a to reduce the stress at the rotational joint. The rolling members 141 of this embodiment can reduce the resistance during the mutual transfer of the flexible display panel 20 on the first surface 10a and the second surface 10b, and improve the protection effect of the flexible display panel 20.

At least a portion of the end of the flexible display panel 20 on the second surface 10b extends into the second receiving cavity 17 through the opening of the second receiving cavity 17 and is received in the rolling device 30.
It should be noted that, based on the mutual transfer process of the flexible display panel 20 on the first surface 10a and the second surface 10b, the winding device 30 is arranged to ensure that the flexible display panel 20 is always attached to the support body 10 in the transfer process, and the flat state is maintained, so as to ensure the structural stability and stable display effect of the display device 100. When the flexible display panel 20 on the first surface 10a is transferred to the second surface 10b, the winding device 30 performs a winding stroke, and when the flexible display panel 20 on the second surface 10b is transferred to the first surface 10a, the winding device 30 performs an unwinding stroke.
And, on the second surface 10b, the surface of the flexible display panel 20 located outside the second receiving cavity 17 is flush with the second surface 10b which is not covered with the flexible display panel 20. Such an arrangement can ensure flatness of the second surface 10b and improve the aesthetic appearance of the display device 100.
Specifically, as shown in fig. 4 and 13, the flexible display panel 20 includes a flexible panel body 21 and a flexible pulling plate 22 located at an end of the flexible panel body 21, and the strength of the flexible pulling plate 22 is greater than that of the flexible panel body 21. The flexible traction plate 22 is received in the winding device 30. It should be noted that, because the flexible display panel 20 has low strength and high flexibility, when the flexible display panel is stored in the winding device 30 and is wound or unwound, the display area of the flexible display panel 20 is damaged, and therefore the flexible pulling plate 22 is disposed at the end of the flexible panel body 21 of the flexible display panel 20 in this embodiment. Although flexible panel body 21 and flexible traction plate 22 are flexible material and make, the intensity of flexible traction plate 22 is greater than the intensity of flexible panel body 21, not only can reduce the damage of flexible traction plate 22 in the rolling in-process like this, improve coiling mechanism 30 and flexible display panel 20's stability of being connected, guarantee that the rolling process is steady to be gone on, and flexible traction plate 22 does not belong to flexible display panel 20's display area moreover, therefore the rolling process can not influence flexible display panel 20's normal demonstration.
Specifically, at least two support members are rotatably coupled by a damping shaft 40. It should be noted that the damping rotation shaft 40 has a certain damping force during the rotation, and the rotation can be performed only when the external force is greater than the damping force. The present embodiment employs the damping rotating shaft 40 to connect at least two supporting members, so that the at least two supporting members can stably maintain the rotating state with the rotating angle when rotating to any angle, thereby maintaining the using state shown in fig. 14 to 16. The gravity of any one of the supporting members is not enough to cause the damping rotation shaft 40 to rotate, and the supporting member can be caused to rotate only by applying an external force to any one of the supporting members by a human, so that the stability of the display apparatus 100 in use can be improved.
As an implementation manner, the supporting portion 13 on the first surface 10a side is fixedly connected to the flexible display panel 20, and the fixed connection may be an adhesive or a magnetic attraction, which is not limited in this embodiment, so as to improve the installation stability of the flexible display panel 20 on the supporting body 10, and at the same time, not affect the folding or sliding stretching process of the display device 100.
