All other embodiments that can be obtained by a person skilled in the art without making any inventive step based on the embodiments in the present application belong to the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a display device according to the present application, which includes a flexible screen 11, a rotating shaft 12, and at least two first supporting bars 13. One end (the end close to the right in fig. 1) of the flexible screen body 11 is fixed on the rotating shaft 12, so that the flexible screen body 11 can be wound and unwound along with the rotation of the rotating shaft 12. In fig. 1, the rotating shaft 12 rotates clockwise to wind the flexible screen 11 on the rotating shaft 12, and the rotating shaft 12 rotates counterclockwise to unwind the flexible screen 11 to a flat state, where fig. 1 shows the flat state of the flexible screen 11.
The at least two first supporting strips 13 are arranged at intervals along the axial direction of the rotating shaft 12, the flexible screen body 11 is supported on the first supporting strips 13, and the rotating shaft 12 further winds and unwinds the first supporting strips 13 along the length direction (i.e., the X direction in fig. 1) of the first supporting strips 13. Referring to fig. 2 in further conjunction with fig. 1, fig. 2 is a schematic structural diagram of the display device in fig. 1 from another viewing angle. Fig. 2 is a top view from bottom to top in the Y direction in fig. 1, and the Z direction in fig. 2 is the axial direction of the rotating shaft 12, in this embodiment, the display device includes two first supporting bars 13, which are respectively disposed near two sides of the flexible screen body 11 in the X direction and support the flexible screen body 11. When the rotating shaft 12 rotates, the first supporting bar 13 and the flexible screen body 11 are simultaneously wound or unwound. In other embodiments, other numbers of first support bars 13 may also be provided, such as three, four, etc.
Referring to fig. 3 and 4 in further conjunction with fig. 1-2, fig. 3 is an enlarged schematic view of a region shown by a dashed line frame a in fig. 1, and fig. 4 is an enlarged schematic view of a region shown by a dashed line frame B in fig. 2. In the present embodiment, each first supporting strip 13 is provided with a plurality of holes 130 spaced apart from each other along the length direction (i.e., X direction) of the first supporting strip 13, the rotating shaft 12 is provided with at least two boss assemblies spaced apart from each other along the axial direction (i.e., Z direction) of the rotating shaft 12, each boss assembly includes a plurality of bosses 120 spaced apart from each other along the circumferential direction of the rotating shaft 12, and when at least two first supporting strips 13 are wound on the rotating shaft 12, the bosses 120 in the boss assemblies are sequentially inserted into the holes 130 of the corresponding first supporting strips 13. That is, each first supporting bar 13 corresponds to one boss assembly, and when the flexible screen body 11 is rolled, the opening 130 on the first supporting bar 13 and the boss 120 in the corresponding boss assembly are engaged with each other. The embodiment is provided with two first supporting strips 13, and then two boss assemblies are arranged on the rotating shaft 12, respectively close to the rotating shaft 12 along two axial ends thereof, and respectively correspond to the positions of the first supporting strips 13, so that the bosses 120 can be just embedded into the corresponding holes 130.
In this embodiment, when the flexible screen body 11 is wound or unwound along with the rotation of the rotating shaft 12, the opening 130 on the first supporting bar 13 and the boss 120 in the corresponding boss assembly are embedded with each other, so that the flexible screen body 11 is always kept in a flat state, and the abnormal probability of the edge tilting thereof is reduced. Moreover, the pulling force provided by the rotation shaft is mainly uniformly received by the first support bar 13 along the length direction thereof due to the multiple fitting processes of the openings 130 and the corresponding bosses 120. Therefore, the flexible screen body can improve the smoothness of the flexible screen body in the curling process and weaken the stress of the flexible screen body in the curling process, so that the probability of generating black spots and other problems when the flexible screen body is lightened is reduced, and the service life of the flexible screen body is prolonged.
Further, with continued reference to fig. 1-4, the display device of the present application further includes an adhesive layer 14 disposed between the flexible screen body 11 and the first support bar 13 for adhering the flexible screen body 11 and the first support bar 13. The material of the adhesive layer 14 may be an optically Clear adhesive oca (optical Clear adhesive), and an orthographic projection of the adhesive layer 14 on the flexible screen body 11 is located within an orthographic projection of the first support bar 13 on the flexible screen body 11, so that on one hand, the first support bar 13 may not fall off due to a bonding effect, and on the other hand, adhesion to impurities such as dust is reduced, thereby improving reliability of the display device of the present application.
In some embodiments, with continued reference to fig. 1-4, the plurality of bosses 120 of each boss assembly are equally spaced along the circumference of the rotating shaft 12, the plurality of openings 130 of each first supporting bar 13 are equally spaced along the length direction of the first supporting bar 13, and the distance d1 between adjacent bosses 120 is equal to the distance d2 between adjacent openings 130. The arrangement can ensure the accuracy of mutual embedding between the open hole 130 on the first support bar 13 and the boss 120 in the corresponding boss assembly, thereby improving the smoothness of the flexible screen body 11 in the curling process, weakening the stress of the flexible screen body 11 in the curling process, and further reducing the probability of generating problems such as black spots when the flexible screen body 11 is lightened.
In this embodiment, the distance d2 between the adjacent holes 130 on the two first supporting bars 13 is set to be the same, that is, the two first supporting bars 13 are completely the same, in other embodiments, the distance d2 between the adjacent holes 130 on the two first supporting bars 13 may be set to be different, as long as d2 is equal to the corresponding d 1.
In the display device of the present application, when the flexible screen 11 is rolled on the rotating shaft 12, the flexible screen 11 may not cover the surface of the rotating shaft 12 last time, that is, the size of the flexible screen 11 in the X direction may be larger than the circumference of the rotating shaft 12, even several times of the circumference. It can be seen that when the first supporting bar 13 is rolled on the rotating shaft 12, the partial openings 130 are overlapped with each other on the rotating shaft 12, and the bosses 120 are simultaneously embedded into at least two openings 130 overlapped with each other.
In some embodiments, with continued reference to fig. 1-4, the boss 120 and the opening 130 are circular or polygonal in shape (e.g., square, regular octagon, etc.). Preferably, the shape of the boss 120 is the same as that of the opening 130, for example, both are circular, which facilitates the engagement between the boss 120 and the opening 130 during the rolling process of the flexible screen body 11, and reduces the possibility of jamming during the rolling process of the flexible screen body 11. Of course, the shape of the bosses 120 may be configured differently from one boss assembly to another.
Further, the boss 120 and the opening 130 are in clearance fit, that is, the size of the boss 120 is slightly larger than that of the opening 130, so that the boss 120 and the opening 130 can be easily engaged and disengaged during the rolling process of the flexible screen body 11. Preferably, the gap width between the boss 120 and the opening 130 in the axial direction of the rotating shaft 12 is less than or equal to 0.2mm, for example, the gap width is 0.2mm, 0.15mm, 0.1mm, or 0.05 mm. For example, the bosses 120 are circular with a diameter of 1mm, the apertures 130 are circular with a diameter of 1.2mm, and the spacing d1 between adjacent bosses 120 is equal to the spacing d2 between adjacent apertures 130. In this embodiment, the boss 120 and the opening 130 can be smoothly embedded in the curling process of the flexible screen body 11, and the boss 120 does not have too much moving space in the opening 130 after the embedding, so that the smoothness of the flexible screen body 11 is further improved, the pulling of the flexible screen body 11 is weakened, and the service life of the display device of the present application can be prolonged.
In some embodiments, with continued reference to fig. 4, the side edge of the first supporting bar 13 is provided with a wave structure, such as a sine wave, a sawtooth wave, a square wave, etc. Preferably, the wave structure is provided at the side edges of at least two first support struts 13 facing each other. The side edges of the first supporting strips 13 are arranged to be of the wavy structures, so that the rigidity of the first supporting strips 13 in the curling direction in the process of following the flexible screen body 11 to curl can be reduced, and the stress of the flexible screen body 11 in the curling process can be reduced.

Fig. 5 schematically shows a case where two first supporting bars 23 and two second supporting bars 25 cooperate to form a rectangular frame structure in which the second supporting bar 25 on the right side is caught by the rotating shaft 22. Furthermore, the flexible screen body 21 is further supported on at least two second support bars 25. That is to say, the rectangular frame structure formed by the two first supporting bars 23 and the two second supporting bars 25 is located on the surface of one side of the flexible screen body 21 facing the rotating shaft 22, so that on one hand, the flexible screen body 21 can be supported, and on the other hand, the flexible screen body 21 can be wound or unwound onto the rotating shaft 22 along with the flexible screen body 21.
