At least two sub-boards 11 are provided with fixing members 20. The flexible display panel 30 is provided on the support plate 10. When the flexible display panel 30 is in a folded state, the telescopic member 40 is contracted, and the telescopic member 40 is connected with the fixing member 20 of the sub-board 11. When the flexible display panel 30 is in the unfolded state, the telescopic members 40 are stretched, and the telescopic members 40 are fixedly connected with the fixing members 20 of the two sub-boards 11 respectively.
The arrangement of the first folding slit 12 and the second folding slit 13 of the support plate 10 in the folding display device 100 of the embodiment of the application satisfies the three-pump folding mode, so that the support plate 10 drives the flexible display panel 30 to be synchronously unfolded and stored according to the three-pump folding mode, and the three-pump folding has a slight angle deviation due to the adjacent sections in the folding positions, so that the effect of reducing the maximum folding curvature can be achieved, and the stress born by the folding region in the folding process is reduced. Meanwhile, the folding area ratio can be effectively improved by the three-pump folding mode, so that the volume of the folded display device 100 can be effectively reduced, and the display device can be applied to more application scenes. In addition, the telescopic member 40 and the fixing members 20 on the at least two sub-boards 11 are matched, so that the stretching shape of the telescopic member 40 can stably maintain the distance between the at least two sub-boards 11 of the support board 10 when the flexible display panel 30 is in the unfolded state, and further, the flatness stability of the flexible display panel 30 after being unfolded is ensured. When the flexible display panel 30 is in a folded state, the telescopic member 40 is contracted to effectively reduce the volume of the folded display device 100.

The plurality of sub-boards 11 may be arranged in a rectangular array, and the extending direction of the first folding slit 12 is parallel to the extending direction of the rows of the plurality of sub-boards 11. The first folding slit 12 is divided by a plurality of second folding slits 13 into a plurality of folding sub-slits 121 connected in sequence. The arrangement is such that the foldable directions of the adjacent two folding sub-slits 121 in the same first folding slit 12 are opposite, and the foldable directions of the corresponding two folding sub-slits 121 in the column direction are opposite to each other in the adjacent two first folding slits 12. And the folding directions of the adjacent two second folding slits 13 are opposite. Referring to fig. 3, one embodiment of the folding method is as follows: the direction towards the flexible display panel 30 is defined as the inner side and the direction away from the flexible display panel 30 is defined as the outer side. The folding direction of the folding sub-slit 121 of the first 1 st first folding slit 12 from top to bottom is foldable to the outside, and the folding direction of the folding sub-slit 121 of the first 2 nd first folding slit 12 is foldable to the inside. The 1 st second folding slit 13 from left to right is foldable to the outside, and the 2 nd second folding slit 13 is foldable to the inside.
Alternatively, referring to fig. 4 to 6, the foldable display device 100 further includes a frame 80 and at least two magnetic members 90, wherein the frame 80 is sleeved on the peripheral side of the flexible display panel 30, the two magnetic members 90 are disposed in the frame 80, and when the flexible display panel 30 is in an unfolded state, one of the magnetic members 90 is located on a side of the sub-board 11 of the first corner 14 of the support board 10, and the other magnetic member 90 is located on a side of the sub-board 11 of the second corner 15 of the first corner 14 of the support board 10, which are diagonally disposed with respect to each other. When the flexible display panel 30 is in the folded state, the magnetic member 90 at the first corner 14 is magnetically fixed with the magnetic member 90 at the second corner 15. Wherein, the periphery of the flexible display panel 30 is sleeved by the frame 80 to protect the same. Meanwhile, in order to ensure the stability of the folded state of the plurality of sub-boards 11, two magnetic pieces 90 are disposed in the frame 80, one magnetic piece 90 is located on the side of the sub-board 11 at the opposite first corner 14 of the support board 10, and the other magnetic piece 90 is located on the side of the sub-board 11 at the second corner 15 of the support board 10, where the first corner 14 of the support board 10 is diagonally disposed, so that when the flexible display panel 30 is in the folded state, the frame 80 is folded synchronously, so that the two magnetic pieces 90 are in the stacked state and are magnetically fixed, thereby improving the stability of the folded state. Of course, a plurality of magnetic members 90 may be provided to further improve the stability of magnetic fixation, for example, the first magnetic member 91 and the second magnetic member 92 are disposed adjacent to the first side and the second side of the sub-board 11 at the first corner 14, and the third magnetic member 93 and the fourth magnetic member 94 are disposed adjacent to the third side and the fourth side of the sub-board 11 at the second corner 15, so that when the flexible display panel 30 is in the folded state, the first magnetic member 91 is magnetically fixed with the third magnetic member 93, and the second magnetic member 92 is magnetically fixed with the fourth magnetic member 94, so as to further improve the stability of the folded state.
In addition, referring to fig. 6 and 7, the folder 40 may have a bar shape or a plate shape, thereby providing a supporting function to secure stability of the flexible display panel 30 after being unfolded, while avoiding the folder 40 from occupying a large volume. When the flexible display panel 30 is in the folded state, the telescopic member 40 is connected with the fixing member 20 of the sub-board 11, wherein only one end of the telescopic member 40 can be fixed, so that the other end of the telescopic member 40 is in the active state, and the position of the telescopic member 40 can be flexibly set in the folded state, or both ends of the telescopic member 40 can be completely fixed, so that the overall stability of the folded display device 100 is ensured.
Alternatively, the two sub-boards 11 located at opposite corners of the edge of the support board 10 are respectively provided with a fixing member 20, and when the flexible display panel 30 is in the unfolded state, the telescopic members 40 are in an extended state, and the telescopic members 40 are respectively connected with the fixing members 20 of the two sub-boards 11 located at opposite corners of the edge. It can be understood that the flexible display panel 30 is easily moved between the two sub-boards 11 in the unfolded state due to the long distance between the two sub-boards 11 at the opposite corners of the edge in the support board 10, so that the stability of the flexible display panel 30 after being unfolded is further ensured by connecting the stretching-shaped telescopic members 40 with the fixing members 20 of the two sub-boards 11 at the opposite corners of the edge, respectively. In addition, the fixing members 20 may be disposed on the plurality of sub-boards 11, so that the telescopic members 40 may be sleeved on the fixing members 20 of any two sub-boards 11 when in the extended state according to the requirement, so as to improve the flexibility of use.
In some embodiments, referring to fig. 6 and 7, the fixing member 20 includes a positioning column 21, both ends of the telescopic member 40 are provided with positioning holes 40a, the positioning column 21 is connected to the surface of the sub-board 11 facing away from the flexible display panel 30, and when the flexible display panel 30 is in the unfolded state, the positioning holes 40a are sleeved in a positioning column 21. The positioning column 21 may be fixedly connected to the daughter board 11, so as to ensure the stability of the support of the positioning column 21. Meanwhile, the positioning hole 40a is formed in the telescopic piece 40, so that the stability of the telescopic piece 40 in the unfolding state is guaranteed through the matching of the positioning hole 40a and the positioning column 21, and meanwhile the telescopic piece 40 is convenient to install and detach when being switched between the unfolding state and the folding state. It should be noted that, the fixing member 20 may also be provided with a structure of a limiting slot, so that the telescopic member 40 and the limiting slot may also be mounted and dismounted in a clamping manner.
Further, the fixing member 20 further includes a limiting post 22, and the limiting post 22 is connected to a surface of the daughter board 11 facing away from the flexible display panel 30 and is spaced from the positioning post 21. When the flexible display panel 30 is in a folded state, the positioning hole 40a of the telescopic member 40 is sleeved on one of the positioning column 22 and the positioning column 21 of the same sub-board 11, and the other positioning hole 40a of the telescopic member 40 is sleeved on the other of the positioning column 22 and the positioning column 21 of the same sub-board 11. In order to avoid the easy shaking of the telescopic member 40 in the folded state, the two ends of the telescopic member 40 in the contracted state are completely limited by the limiting posts 22. It should be noted that the shape and arrangement of the limiting post 22 may be the same as the positioning post 21, so as to facilitate the installation and removal of the telescopic member 40. Further, the distance between the stopper post 22 and the positioning post 21 is greater than or equal to the length of the contractible telescopic member 40.
Further, the positioning posts 21 and the limiting posts 22 are respectively located at opposite angles of the same sub-board 11. It should be noted that, when the flexible display panel 30 is in a folded state, and the flexible display panel 40 is in a contracted state, one end of the flexible display panel 40 is sleeved on the limiting post 22, the other end is sleeved on the positioning post 21, and the fixed section and the extended section are overlapped, i.e. the length of the flexible display panel 40 is equal to that of the fixed section. When the flexible display panel 30 is in the unfolded state, at this time, one end of the expansion element 40 is separated from the limiting post 22, and after the other end of the expansion element 40 is rotated, the expansion element 40 is stretched and then sleeved on the positioning post 21 at the other sub-board 11, i.e. the length of the expansion element 40 is the fixed length at this time, and the length of the extending section is increased. And through locating the locating column 21 and spacing post 22 respectively in the diagonal department of same daughter board 11 to make the distance between locating column 21 and the spacing post 22 in same daughter board 11 the farthest, and then so that the fixed section can set up longer, thereby can reduce the setting length of extension. Further, the extension sections can be arranged at the two ends of the fixed section, so that the extension sections can be effectively prevented from moving too long, and the operation of a user is facilitated. Alternatively, the fixed and extended sections may be bent to switch between an extended and a contracted configuration.

So that the extensible member 40 is in the folding state, also synchronous in the outermost side after a plurality of sub-boards 11 are folded, thereby can effectively avoid extensible member 40 to the in-process that a plurality of sub-boards 11 are unfolded and folded to cause the influence, the operating personnel of being convenient for install and dismantle extensible member 40 simultaneously.
Further, the foldable display device 100 further includes a flexible circuit board 70, and the flexible circuit board 70 is disposed on a surface of one of the sub-boards 11 facing away from the flexible display panel 30 and electrically connected to the flexible display panel 30. The flexible circuit board 70 is used for controlling the flexible display panel 30, and the flexible circuit board 70 is disposed on a surface of one of the sub-boards 11 facing away from the flexible display panel 30, so as to avoid influencing the first folding slit 12 and the second folding slit 13 during folding and unfolding. Further, the flexible circuit board 70 may be located at the first sub-board 111 and spaced from the limiting posts 22 and the positioning posts 21, so that when the flexible display panel 30 is in a folded state, the flexible circuit board 70 is also located at the outermost side of the folded sub-boards 11 synchronously, thereby further effectively avoiding the influence of the flexible circuit board 70 on the unfolding and folding processes of the sub-boards 11, and facilitating the installation and disassembly of the flexible circuit board 70 by an operator.

After the telescopic member 40 is released from the support, the first folding elastic piece 50 and the second folding elastic piece 60 can provide torque to twist the plurality of sub-boards 11 in a predetermined direction to form a half-folded state, so that a subsequent user can push and pull once to form a complete fold, that is, the first folding elastic piece 50 and the second folding elastic piece 60 provide folding initial force, so that the user can fold and store conveniently.
Further, the first folding elastic piece 50 includes a first bending portion 51 and two first fixing portions 52 connected to two opposite sides of the first bending portion 51, the two first fixing portions 52 are respectively disposed on two adjacent sub-boards 11, and the first bending portion 51 protrudes toward the flexible display panel 30.
