In the related art, the scroll type display panel is provided with only one scroll, so that the flexible display panel on the scroll can be unfolded or folded, the area of the display panel curled on a single scroll is limited, and the area of the display module group capable of curling or unfolding of the scroll type display panel is small.

Based on this, the present exemplary embodiment provides a scroll structure for a scroll type display panel, as shown in fig. 1 to 4, fig. 1 is a schematic structural view of an exemplary embodiment of the scroll structure of the present disclosure, fig. 2 is a schematic structural view of an exemplary embodiment of the scroll type display panel of the present disclosure, fig. 3 is a schematic structural view of the first slider and the second slider of fig. 1, and fig. 4 is a side view of the scroll type display panel of fig. 2. The scroll type display panel comprises a displayable module 0, and the scroll structure comprises: the first slider 11, the second slider 12, the first support shaft 21, the second support shaft 22, the second slider 12 and the first slider 11 being relatively movable in the first direction X; the first support shaft 21 is connected to the first sliding body 11, the first support shaft 21 is used for supporting the display module 0, and an axial direction Y1 of the first support shaft 21 may intersect the first direction X, for example, the axial direction Y1 of the first support shaft 21 may be perpendicular to the first direction X; the second support shaft 22 may be connected to the second slider 12, the second support shaft 22 may be used to support the display module 0, and an axial direction Y2 of the second support shaft 22 may intersect the first direction X, for example, the axial direction Y2 of the second support shaft 22 may be perpendicular to the first direction X, and the axial direction Y2 of the second support shaft 22 may be parallel to the axial direction Y1 of the first support shaft 21.

As shown in fig. 1 to 4, the display module located on one side of the first support shaft 21 and the second support shaft 22 away from the first slider 11 and the second slider 12 may form an unfolding surface of the scroll display panel, and the first slider 11 and the second slider 12 are controlled to relatively move in the first direction X, so as to control an unfolding area of the display module. For example, when the first slider 11 moves to a side away from the second slider 12, the spreading surface of the scroll display panel increases, and when the second slider 12 moves to a side away from the first slider 11, the spreading surface of the scroll display panel increases, and since the scroll display panel is provided with two support shafts, the scroll display panel can have a larger spreading area.

In the present exemplary embodiment, as shown in fig. 1 to 4, the display module 0 may be wound around the first support shaft 21 half a turn, and the display module 0 may be wound around the second support shaft 22 half a turn.

When the first sliding body 11 slides to the side far away from the second sliding body 12, the first supporting shaft 21 rolls relative to the first supporting rod 111, and the friction force between the first supporting shaft 21 and the display module 0 can be static friction force, so that the friction force between the first supporting shaft 21 and the display module and the friction force between the second supporting shaft 22 and the display module can be reduced, and the risk that the display module is damaged during unfolding and folding is reduced. It should be appreciated that in other exemplary embodiments, the first support shaft 21 may also be fixedly connected to the first slider 11, and the second support shaft 22 may be fixedly connected to the second slider 12.

As shown in fig. c, when the first slider 11 moves to the side away from the second slider 12, the first support shaft 21 and the third support shaft 53 simultaneously move to the side away from the second slider 12, the relative positions of the first support shaft 21 and the third support shaft 53 are not changed, and the display module located on the side of the first support shaft 21 facing the first sliding portion 112 rotates to the side of the first support shaft 21 facing away from the first sliding portion 112, so that the expansion surface of the scroll type display panel increases. Similarly, when the second sliding body 12 moves to the side far away from the first sliding body 11, the second supporting shaft 22 and the fourth supporting shaft 54 simultaneously move to the side far away from the first sliding body 11, the relative positions of the second supporting shaft 22 and the fourth supporting shaft 54 are not changed, and the display module located on the side of the second supporting shaft 22 facing the second sliding portion 121 rotates to the side of the second supporting shaft 22 facing away from the second sliding portion 121, so that the unfolding surface of the scroll type display panel is increased. As shown in fig. b, the scroll type display panel may move the first slider 11 and the second slider 12 simultaneously to adjust the unfolding area of the display module, and may also move either the first slider 11 or the second slider 12 independently to adjust the unfolding area of the display module.

It should be noted that, the tensioning strip 51 may have a certain elasticity, and the tensioning strip 51 may have a certain shrinkage force when the installation is completed, and the shrinkage force may provide a pretightening force to the display module. It should be understood that in other exemplary embodiments, the pretensioner 5 may have other configurations, which are within the scope of the present disclosure.

In this exemplary embodiment, as shown in fig. 6, a schematic structural diagram of an exemplary embodiment of the tension strip of the present disclosure is shown. The tension bar 51 may include: a first extension 513, a second extension 514, a first end of the first extension 513 may form the first end 511 of the tension bar 51; a first end of the second extension 514 may be connected to a second end of the first extension 513, and a second end of the second extension 514 may be used to form the second end 512 of the tension bar 51. Wherein, the second extension portion 514 may have a bar-shaped opening 5141 formed thereon to extend in an extension direction thereof, and a first end of the first extension portion 513 may pass through the bar-shaped opening 5141 to form a ring-shaped structure wound around the third support shaft 53 and the fourth support shaft 54. The arrangement may be such that the force of the tensioning strip 51 on both the third support shaft 53 and the fourth support shaft 54 extends in the first direction. In this exemplary embodiment, as shown in fig. 1 to 4, the pretensioner 5 may include two tensioning strips 51, and the two tensioning strips 51 may be distributed at intervals along the axial direction of the third support shaft 53, where the arrangement may enable the pretensioner 5 to have relatively uniform pretensioning force on different positions of the third support shaft 53 and the fourth support shaft 54. It should be appreciated that in other exemplary embodiments, the pre-tension member 5 may further include other numbers of tension bars 51, for example, the pre-tension member 5 may further include one tension bar 51 or a plurality of tension bars 51, and the plurality of tension bars 51 may be spaced apart along the axial direction of the third support shaft 53.

In this exemplary embodiment, as shown in fig. 1 to 4, the first sliding body 11 may further include: a third support bar 113, the third support bar 113 may be connected to a side of the first sliding part 112 facing the first support shaft 21, and the third support bar 113 may be located between the first support shaft 21 and the second support shaft 22 in the first direction X; the second slider 12 may further include: a fourth support bar 124, the fourth support bar 124 may be connected to a side of the second sliding portion 121 facing the second support shaft 22, and the fourth support bar 124 may be located between the first support shaft 21 and the third support bar 113 in the first direction X, and an axial direction of the third support bar 113 and an axial direction of the fourth support bar 124 may be parallel. The third supporting shaft 53 may be provided with a through hole along an axial direction thereof, and the third supporting rod 113 may be sleeved in the through hole of the third supporting shaft 53 in a rolling manner, so that the third supporting shaft 53 may be connected to the third supporting rod 113 in a rolling manner. The fourth support shaft 54 may be provided with a through hole along an axial direction thereof, and the fourth support rod 124 may be sleeved in the through hole of the fourth support shaft 54 in a rolling manner, so that the fourth support shaft 54 may be connected to the fourth support rod 124 in a rolling manner. When the first sliding body 11 moves relative to the second sliding body 12, the third supporting shaft 53 rolls relative to the third supporting rod 113, and the friction force between the tensioning strip 51 and the third supporting shaft 53 is static friction force, so that the friction force between the tensioning strip 51 and the third supporting shaft 53 can be reduced, and the service life of the tensioning strip 51 is prolonged.

As shown in fig. 3 and 4, each of the first sliding portion 112 and the second sliding portion 121 may have a plate-like structure, and the first sliding portion 112 and the second sliding portion 121 may be disposed in parallel. The distance between the third support shaft 53 and the first sliding portion 112 may be equal to the distance between the fourth support shaft 54 and the first sliding portion 112, that is, when the first sliding portion 112 is parallel to the horizontal plane, the third support shaft 53 and the fourth support shaft 54 may be located at the same horizontal position, and when the first sliding body 11 and the second sliding body 12 relatively move away from each other, the third support shaft 53 and the fourth support shaft 54 may serve as a limiting structure to avoid the first sliding body 11 and the second sliding body 12 from being separated.

In the present exemplary embodiment, each of the first support shaft 21, the second support shaft 22, the third support shaft 53, and the fourth support shaft 54 may be a cylinder; the first support shaft 21 may have a larger cylindrical radius than the third support shaft 53, and the second support shaft 22 may have a larger cylindrical radius than the fourth support shaft 54. The first support shaft 21 and the second support shaft 22 are designed with larger radius, so that the bending radius of the display module can be increased, and the damage risk of the display module is reduced. In addition, the radius of the third supporting shaft 53 and the radius of the fourth supporting shaft 54 are adjusted to adjust the resistance when the first sliding body 11 and the second sliding body 12 relatively move, when the radius of the third supporting shaft 53 and the radius of the fourth supporting shaft 54 are smaller, the moment of acting force of the tensioning strip 51 on the third supporting shaft 53 and the moment of acting force of the fourth supporting shaft 54 are smaller, the resistance when the first sliding body 11 and the second sliding body 12 relatively move is larger, when the radius of the third supporting shaft 53 and the radius of the fourth supporting shaft 54 are larger, the moment of acting force of the tensioning strip 51 on the third supporting shaft 53 and the moment of acting force of the fourth supporting shaft 54 are larger, and the resistance when the first sliding body 11 and the second sliding body 12 relatively move is smaller. In the present exemplary embodiment, the cylindrical radius of the first support shaft 21 may be equal to the cylindrical radius of the second support shaft 22, and the cylindrical radius of the third support shaft 53 may be equal to the cylindrical radius of the fourth support shaft 54. It should be appreciated that in other exemplary embodiments, the radii of the first support shaft 21, the second support shaft 22, the third support shaft 53, and the fourth support shaft 54 may have other size relationships. The first support shaft 21, the second support shaft 22, the third support shaft 53, and the fourth support shaft 54 may have other shapes, for example, any one of the first support shaft 21, the second support shaft 22, the third support shaft 53, and the fourth support shaft 54 may be formed of a plurality of concentric cylinders with different radii.

The present exemplary embodiment also provides a scrolling display panel, which may include the above scrolling structure and a display module. The scroll display panel is described in detail in the above, and will not be described here.

The elastic modulus of the first fixing structure 04 and the second fixing structure 05 may be smaller than the elastic modulus of the flexible display panel 03, the first fixing structure 04 may form a first end of the display module 0, and the second fixing structure 05 may form a second end of the display module 0. Because tensioning strip 51 is connected in the local position of display module assembly 0, the local position that is located of display module assembly and is connected with tensioning strip 51 can take place local arch under tensioning strip 51 pretightning force to easily cause the display module assembly to damage. In this exemplary embodiment, the first fixing structure 04 and the second fixing structure 05 are added at two ends of the flexible display panel 03, the first fixing structure 04 and the second fixing structure 05 are respectively connected with the whole side edges of the flexible display panel, and the first fixing structure 04 and the second fixing structure 05 are respectively connected with the tensioning strips 51, so that the flexible display panel can be prevented from being locally protruded, and the risk of damage of the display module is reduced.

In this exemplary embodiment, as shown in fig. 7, the display module 0 may further include: a plurality of chip ICs, a plurality of which may be fixedly connected to the first end 031 of the flexible display panel. I.e. the first fixing structure 04 may be provided at the IC side of the flexible display panel or opposite to the IC side. The chip IC may be a source driver chip. In addition, the display module may further include a flexible circuit board FPC, which may also be disposed at the first end 031 of the flexible display panel, and the flexible circuit board FPC may be integrated with chips such as a driving IC and a touch IC.

Fig. 8 is a schematic structural diagram of a display module according to another exemplary embodiment of a scroll display panel of the present disclosure. In this exemplary embodiment, the flexible display panel may further include a third end 033 connected between the first end 031 and the second end 032 thereof, and the display module may further include: a plurality of chip ICs, a plurality of which may be fixedly connected to the third end 033 of the flexible display panel. In addition, the display module can also include a flexible circuit board FPC, the flexible circuit board FPC can also be arranged at the third end 033 of the flexible display panel, and chips such as a driving IC, a touch IC and the like can be integrated on the flexible circuit board FPC. I.e. the first and second ends of the flexible display panel are arranged on adjacent sides of the IC.

Note that, since the positions where the chip IC and the flexible circuit board FPC are provided cannot be curled, the area where the display module shown in fig. 7 can be curled is obviously larger than the area where the display module shown in fig. 8 can be curled.
