It should be noted that, in case of conflict, different features in the embodiments of the present application may be combined with each other.
Referring to fig. 1, the rolled display generally includes a rotating shaft 100 and a flexible display 200, one side of the flexible display 200 may be disposed on the rotating shaft 100, and in a non-use state, the rotating shaft 100 may rotate along a direction R1 shown in fig. 1, so that the flexible display 200 is wound around the rotating shaft 100; in the using state, the rotating shaft 100 can rotate along the direction R2 shown in fig. 1, so that the flexible display screen 200 is unfolded relative to the rotating shaft 100, so as to increase the display area visible by the flexible display screen 200, and facilitate the use of the user.
However, the inventor finds that, in the process of curling the flexible display screen 200, a certain curling pressure is generated on the surface of the flexible display screen 200, so that a part of the flexible film layer of the flexible display screen 200 is always pushed to one direction, and a glue stacking phenomenon is generated, thereby affecting the light transmission effect of the flexible display screen 200, and even causing damage to the flexible display screen 200.
In view of this, the present embodiment provides a solution that can alleviate the problem of glue stacking generated in the process of curling the flexible display screen to a certain extent, and the solution provided by the present embodiment is described in detail below.
Referring to fig. 2, fig. 2 is an electronic device provided in this embodiment, and the electronic device may include a rotating shaft 100, a flexible display 200, and a screen rolling assembly 300.
The rotating shaft 100 may be cylindrical, and one end of the flexible display screen 200 is connected to the rotating shaft 100, so that the flexible display screen 200 can be wound around the rotating shaft 100 or unfolded relative to the rotating shaft 100.
The flexible display screen 200 can be unfolded or wound on the rotating shaft 100 relative to the rotating shaft 100 through the screen rolling assembly 300, and the screen rolling assembly 300 applies a force to the surface of the flexible display screen 200 in a process that the flexible display screen 200 moves relative to the screen rolling assembly 300.
Based on the design, because the screen body rolling component 300 can apply an acting force to the surface of the flexible display screen 200 in the moving process of the flexible display screen 200, when the glue stacking structure generated by the curling pressure reaches the screen body rolling component 300, the screen body rolling component 300 can generate reverse blocking thrust to the glue stacking structure, so that the glue stacking problem generated when the flexible display screen 200 is wound on the rotating shaft 100 can be counteracted to a certain extent, and the display effect of the flexible display screen 200 is ensured.
In one possible implementation manner, please refer to fig. 2 again, which includes a first pressing portion 310 and a second pressing portion 320, a gap is formed between the first pressing portion 310 and the second pressing portion 320, and the flexible display 200 can be unfolded with respect to the rotating shaft 100 or wound around the rotating shaft 100 through the gap. Preferably, the gap is parallel to the rotation axis 100.
For example, the flexible display screen 200 may include a first end and a second end, the first end is connected to the rotating shaft 100, the second end may pass through the gap, when the flexible display screen 200 moves in the X1 direction shown in fig. 2 relative to the screen rolling assembly 300, the flexible display screen 200 may be unfolded relative to the rotating shaft 100, and when the flexible display screen 200 moves in the X2 direction shown in fig. 2 relative to the screen rolling assembly 300, the flexible display screen 200 is retracted and wound around the rotating shaft 100.
In this embodiment, the first pressing part 310 and the second pressing part 320 apply a force to the surface of the flexible display 200 during the movement of the flexible display 200 relative to the first pressing part 310 and the second pressing part 320. Preferably, the force is pressure.
Based on the above design, referring to fig. 3, since a gap with a certain width is formed between the first pressing portion 310 and the second pressing portion 320, an acting force can be applied to the two side surfaces of the flexible display 200 in the moving process of the flexible display 200, so that when the glue stacking structure generated by the curling pressure reaches the first pressing portion 310 and the second pressing portion 320, the first pressing portion 310 and the second pressing portion 320 can generate a reverse blocking thrust to the glue stacking structure, thereby offsetting the glue stacking problem generated when the flexible display 200 is wound on the rotating shaft 100 to a certain extent and ensuring the display effect of the flexible display 200.
Further, since the surface of the flexible display panel 200 is subjected to a curling force in a direction toward the flexible display panel 200 and away from the end connected to the rotating shaft 100 during the curling process, in a possible implementation manner, the first pressing portion 310 and the second pressing portion 320 may move relatively close to each other to apply a force to the surface of the flexible display panel 200 when the flexible display panel 200 is unfolded relative to the rotating shaft 100; and relatively moves away when the flexible display 200 is changed from the unfolded state to the state of being wound on the rotating shaft 100, so as to release the acting force applied to the surface of the flexible display 200.
For example, when the flexible display panel 200 is unfolded relative to the rotating shaft 100, referring to fig. 4, the first pressing portion 310 and the second pressing portion 320 may move close to each other until the width of the gap is smaller than D1, so that in the process that the flexible display panel 200 moves in the X1 direction relative to the first pressing portion 310 and the second pressing portion 320, the first pressing portion 310 and the second pressing portion 320 may apply a force in the X2 direction to the glue stacking structure on the surface of the flexible display panel 200, thereby counteracting the glue stacking phenomenon generated when the flexible display panel 200 is wound on the rotating shaft 100.
When the flexible display panel 200 is changed from the unfolded state to the folded state and is wound on the rotating shaft 100, referring to fig. 5, the first pressing portion 310 and the second pressing portion 320 may move away from each other until the width of the gap is greater than D2, so as to release the pressure applied to the surface of the flexible display panel 200, where D2 is greater than D1. In this way, a force facing the X1 direction can be prevented from being applied to the surface of the flexible display screen 200 during the process that the flexible display screen 200 moves towards the X2 direction relative to the first pressing portion 310 and the second pressing portion 320, so that the phenomenon of glue piling is prevented from being aggravated.
In one possible implementation manner, referring to fig. 6, the first pressing portion 310 and/or the second pressing portion 320 includes a roller, and the roller rotates when the flexible display screen 200 moves relative to the screen body rolling assembly 300. So, flexible display screen 200 is relative when the screen body rolls subassembly 300 and moves, can reduce first extrusion 310 and/or second extrusion 320 with the frictional force between the flexible display screen 200 surface avoids flexible display screen 200 is cut and rubbed the damage.
In one possible implementation, the flexible display 200 may be unfolded by an external force. For example, the electronic device may be a mobile phone using a scrolling screen, and a user may pull the flexible display screen 200, so that the flexible display screen 200 drives the rotation shaft 100 to rotate, and the flexible display screen 200 is pulled out relative to the rotation shaft 100 to be unfolded.
In a similar scenario, the electronic device further includes a linkage assembly that drives the first pressing portion 310 and the second pressing portion 320 to approach or move away from each other according to a rotation direction of the rotation shaft 100.
For example, referring to fig. 4 again, when the flexible display 200 is pulled out in the direction X1 shown in fig. 4, the rotating shaft 100 rotates in the direction R2 shown in fig. 4, the linkage assembly may be driven by the rotation of the rotating shaft 100 or the linkage assembly may detect the rotation of the rotating shaft 100, so as to further drive or control the first pressing portion 310 and the second pressing portion 320 to move closer to each other.
Referring to fig. 5 again, when the rotating shaft 100 rotates in the direction R1 shown in fig. 5 to drive the flexible display screen 200 to move in the direction X2 shown in fig. 5, the linkage assembly may be driven by the rotation of the rotating shaft 100 or the linkage assembly may detect the rotation of the rotating shaft 100, so as to further drive the first pressing portion 310 and the second pressing portion 320 to move away from each other or control the first pressing portion 310 and the second pressing portion 320 to move away from each other.
In another possible implementation, the flexible display 200 may be actively deployed. For example, the electronic device may be a television or a display screen of a curtain type using a winding screen, and the electronic device actively implements the unwinding or winding of the flexible display without applying an external force by controlling the rotation direction of the rotating shaft 100.
In a similar scenario, the first pressing portion 310 and/or the second pressing portion 320 may be a roller, and the electronic device further includes a driving component for driving the rotating shaft 100 and the roller to rotate.
For example, referring to fig. 4 again, when it is required to control the flexible display panel 200 to unfold, the first pressing portion 310 and the second pressing portion 320 may be controlled to move close to each other, and then the rotating shaft 100 and the roller are controlled to rotate simultaneously, so that the flexible display panel 200 is unfolded, and a force is applied to the surface of the flexible display panel 200 by the first pressing portion 310 and the second pressing portion 320 during the unfolding process.
Referring to fig. 5 again, when it is required to control the flexible display 200 to be wound, the first pressing portion 310 and the second pressing portion 320 may be controlled to move away from each other to avoid applying pressure to the surface of the flexible display 200. And then, the rotating shaft 100 is controlled to rotate to drive the flexible display screen 200 to wind.
Further, in this embodiment, the driving assembly is configured to drive the rotating shaft 100 and the roller to rotate at the same linear speed. In this way, the flexible display screen 200 between the hinge 100 and the screen rolling assembly 300 can be prevented from being pulled or wrinkled due to the different rotation speeds between the hinge 100 and the screen rolling assembly 300.
In a possible implementation manner, referring to fig. 7, the first pressing portion 310 and/or the second pressing portion 320 are disposed on an elastic member 330, and in a process that the first pressing portion 310 and the second pressing portion 320 apply pressure to the surface of the flexible display screen 200, the elastic member 330 deforms, so that a width of the gap between the first pressing portion 310 and the second pressing portion 320 changes within a set range. Thus, while the first pressing portion 310 and the second pressing portion 320 apply pressure to the surface of the flexible display panel 200, the width of the gap between the first pressing portion 310 and the second pressing portion 320 may be changed to some extent, and when some concave-convex structures on the flexible display panel 200 pass through the first pressing portion 310 and the second pressing portion 320, it may be avoided that the first pressing portion 310 and the second pressing portion 320 apply excessive force to the flexible display panel 200 to damage the flexible display panel.
In a possible implementation manner, referring to fig. 8, the electronic device further includes a housing 400, the rotating shaft 100 is disposed in the housing 400, the housing 400 includes an opening parallel to the rotating shaft 100, and the flexible display 200 can be unfolded relative to the rotating shaft 100 or be wound in the housing 400 through the opening. The housing 400 may be used to protect the flexible display 200 in a rolled state.
Further, the screen rolling component 300 is disposed at the opening of the housing 400. For example, the first pressing portion 310 and the second pressing portion 320 are disposed at the opening of the case 400. Therefore, when the first pressing portion 310 and the second pressing portion 320 are rollers, the first pressing portion 310 and the second pressing portion 320 can also prevent the flexible display screen 200 and the opening of the housing 400 from being scratched, so that the flexible display screen 200 is protected.
In one possible implementation, the area of the screen body rolling assembly 300 in contact with the flexible display screen 200 comprises a flexible material, for example. The region of the first pressing part 310 and/or the second pressing part 320 in contact with the flexible display screen 200 includes a flexible material. Specifically, the contact area of the first pressing portion 310 and/or the second pressing portion 320 with the flexible display 200 may be a silicon gel. Damage to the flexible display screen 200 when the screen body rolling assembly 300 applies force to the flexible display screen 200 can be avoided.
To sum up, the electronic equipment that this application embodiment provided through set up first extrusion portion and second extrusion portion on flexible display screen expandes and winds the route, by first extrusion portion and second extrusion portion expand or wind the in-process at flexible display screen to flexible display screen's surface application effort to can offset the pile of glue problem that produces when flexible display screen is because of coiling in the pivot.
