Referring to fig. 1, a flexible display assembly includes a bending region 100, where the bending region 100 may be bent to enable the flexible display assembly to be folded inwards or outwards, and one or both sides of the bending region 100 may be provided with a planar region 200, or may be both bending regions 100, that is, any position of the flexible display assembly may be bent. The flexible display assembly includes a flexible display screen 10, a first adhesive layer 20, a support layer 30, a second adhesive layer 40, and a filler 60.

The first adhesive layer 20 is disposed on the first surface 301, and the second adhesive layer 40 is disposed on the second surface 302.

Referring to fig. 4, the packing 60 has a major axis 601 and a minor axis 602 perpendicular to each other. When the bending region 100 is in a flat state, the accommodating cavity 501 has a first width W1 in a direction perpendicular to the virtual bending line 101 of the bending region 100, and the long axis 601 of the filling body 60 has a first included angle θ1 with the supporting layer 30.
Referring to fig. 5, when the bending region 100 is in the bending state, the accommodating cavity 501 has a second width W2 in a direction perpendicular to the virtual bending line 101 of the bending region 100, and the long axis 601 of the filling body 60 has a second included angle θ2 with the supporting layer 30; the first width W1 is smaller than the second width W2, and the first included angle θ1 is larger than the second included angle θ2.
In the process of bending the bending region 100, the width of the accommodating cavity 501 in the direction perpendicular to the virtual bending line 101 of the bending region 100 is widened, the stress to which the first adhesive layer 20 and/or the second adhesive layer 40 is subjected during bending is reduced by the widening of the width of the accommodating cavity 501, the first adhesive layer 20 and/or the second adhesive layer 40 is protected from being deformed easily, the filling body 60 rotates or deforms in the accommodating cavity 501 where the filling body 60 is located, and the long axis 601 of the filling body 60 rotates from the state perpendicular to the supporting layer 30 (i.e., the first included angle θ1 is 90 °) to the state parallel to the supporting layer 30 (i.e., the second included angle θ2 is 0 °).
The present application defines that the filler 60 is in the first configuration when the inflection zone 100 is in the flattened state; when the bending region 100 is in the bending state, the filling body 60 is in the second state, the filling body 60 is converted between the first state and the second state through rotation and/or deformation, and the filling body 60 is simultaneously converted when the state of the bending region 100 is converted, so that the practicability of the filling body 60 in the flexible display assembly is improved, and the design improves the application prospect of the flexible display assembly prepared by the embodiment of the application.
Further, in the process of bending the bending region 100, the long axis 601 of the filling body 60 rotates and/or deforms in the direction parallel to the supporting layer 30 toward the accommodating cavity 501, the short axis 602 of the filling body 60 plays a role in supporting the accommodating cavity 501 in the accommodating cavity 501, so that the overall thickness of the flexible display assembly is kept unchanged, the extrusion force applied to the flexible display screen 10 during bending is reduced, the flexible display screen 10 is prevented from being broken, and the service life of the flexible display assembly is prolonged.
In some embodiments, the first included angle θ1 is 90 ° (as shown in fig. 4), the second included angle theta 2 is smaller than or equal to 0 degrees and smaller than or equal to theta 2<90 degrees (as shown in fig. 5 and 6), and the bending of the flexible display component can be realized. The angle of the second included angle θ2 indicates the bending degree of the accommodating cavity 501. The second included angle θ2 of the filling body 60 is inversely related to the bending degree of the accommodating cavity 501 where the filling body 60 is located, that is, the greater the second included angle θ2 (i.e., the closer to the angle of the first included angle θ1), the smaller the bending degree of the accommodating cavity 501 where the filling body 60 is located; the smaller the second included angle θ2 of the packing 60 (i.e., the closer to 0 °), the greater the degree of bending of the receiving cavity 501 in which the packing 60 is located.
In some specific embodiments, the first included angle θ1 between the long axis 601 of the filling body 60 and the supporting layer 30 may be smaller than 90 ° when the bending region 100 is in the flat state, and the second included angle θ2 between the long axis 601 of the filling body 60 and the supporting layer 30 may be larger than 0 ° but smaller than the first included angle θ1 when the bending region 100 is in the bent state.
The filler 60 is a rigid body and/or an elastomer. Wherein the rigidity body can promote the capability of the first adhesive layer 20 and/or the second adhesive layer 40 to maintain the thickness and flatness thereof, which can promote the protection capability of the flexible display screen 10, promote the bending capability of the flexible display assembly, and promote the service life of the flexible display assembly.
The shape of the filling body 60 is not limited as long as it has a long axis 601 and a short axis 602 perpendicular to each other, and may be an ellipsoid or a nearly ellipsoid, for example, an egg-like shape. Referring to fig. 1-6, in the present embodiment, the filling body 60 is an ellipsoid, and the ellipsoid is configured to easily rotate or deform during the deformation of the accommodating cavity 501, so as to improve the ability of the filling body 60 to maintain consistent deformation with the first adhesive layer 20 and/or the second adhesive layer 40. The side wall of the accommodating cavity 501 is set to be a curved surface, the curved surface in the embodiment is a cambered surface, and the side wall of the accommodating cavity 501 is set to be a cambered surface, so that the filling body 60 is easy to rotate and/or deform in the accommodating cavity 501, and the efficiency of state transition of the filling body 60 is improved.
Referring to fig. 4, when the bending region 100 is in a flat state, the curvature of the curved surface of the accommodating cavity 501 is greater than or equal to the curvature of the long end surface of the ellipsoid, and this arrangement mode makes it possible to keep the filling body 60 in a form of standing up in the accommodating cavity 501 when the bending region 100 is in a flat state, that is, the long axis 601 of the filling body 60 is perpendicular to the supporting layer 30, and the short axis 602 is parallel to the supporting layer 30, so that the stress between the filling body 60 and the side wall of the accommodating cavity 501 is small when the accommodating cavity 501 is in a contracted state, thereby alleviating the bending fatigue degree of the flexible display assembly and improving the bending resistance of the flexible display assembly.
Referring to fig. 5-6, when the bending region 100 is in a bending state, the curvature of the curved surface is smaller than or equal to the curvature of the short end surface of the ellipsoid, and this arrangement mode makes the filler 60 in the accommodating cavity 501 when the bending region 100 is in a bending state, reduces the contact area between the filler 60 and the side wall of the accommodating cavity 501, reduces the stress transmission between the filler 60 and the adhesive layer of the accommodating cavity 501, relieves the bending fatigue of the flexible display assembly, and improves the bending resistance of the flexible display assembly.
Referring to fig. 1 and 4, the major axis 601 of the filler 60 is perpendicular to the support layer 30 when the inflection zones 100 are in a flat state. Referring to fig. 6, when the inflection zone 100 is in a fully inflection state, the long axis 601 of the packing 60 is parallel to the support layer 30 and perpendicular to the virtual inflection line 101 of the inflection zone 100.
The filler 60 is a rigid body and/or an elastomer, and in some embodiments, the filler 60 is configured as a rigid body to facilitate rotation within the receiving cavity 501, increase the bend radius of the flexible display screen support assembly, and increase the bend life of the flexible display assembly. In some embodiments, the rigid body comprises a plastic, metal, or glass. Among these, the plastic rigid body has advantages of light weight, wide sources, high fatigue resistance, etc., and in some preferred embodiments, the plastic rigid body is used. It will be appreciated that the filler body 60 is made of a smooth-surfaced material and is more easily rotatable.
Referring to fig. 7, fig. 7 is a schematic structural diagram of a second form of the filler in the flexible display assembly according to the present application.
Referring to fig. 7, the filling body 60 is configured as an elastomer, and during bending of the flexible display screen supporting component, the elastomer deforms in cooperation with the accommodating cavity 501, so as to increase the bending radius of the flexible display screen supporting component, and meanwhile, the elastomer also plays a role in supporting the first adhesive layer 20 and/or the second adhesive layer 40, so as to help improve the bending life of the flexible display screen supporting component. In some embodiments, the elastomeric material comprises rubber. In some specific embodiments, the elastic body is an elastic capsule filled with liquid, and in the process of deformation of the accommodating cavity 501, the liquid filled in the elastic capsule increases the weight of the filling body 60, so that the filling body 60 is easy to rotate and/or deform in the process of deformation of the accommodating cavity 501, which can effectively increase the bending radius of the flexible display screen supporting component and improve the bending life of the flexible display component.
The filling body 60 is a solid body and/or a hollow body. In some specific embodiments, the rigid body is a solid body or a hollow body; the elastic body is solid or hollow. In some specific embodiments, the filling body 60 is provided as a solid body, which plays a role of easy rotation in the accommodating cavity 501, effectively achieves the purpose of increasing the bending radius of the flexible display screen supporting component, and improves the bending life of the flexible display component. In some embodiments, the filler 60 is configured as a hollow body that serves to reduce the weight of the flexible display assembly, reduce bending stresses, and increase bending life.
During the return of the folded region 100 from the folded state to the flat state, the first adhesive layer 20 and the second adhesive layer 40 contract, and during the contraction, the long axis 601 of the filler 60 is pressed by the side wall of the receiving cavity 501, and is turned from the direction parallel to the support layer 30 to the direction perpendicular to the support layer 30, and the state when the filler 60 returns to the flat state, the flexible display assembly returns to the original thickness. The provision of the filler 60 allows the flexible display assembly to easily return to its original thickness. Only the technical solution of providing the accommodation cavity 501 and not providing the filling body 60, the flexible display assembly is easy to deform in the thickness direction, and the flexible display screen 10 is easy to be extruded and damaged. In some embodiments, the present application employs a rigid filler 60 disposed within the receiving cavity 501, which is more advantageous for maintaining the thickness and flatness of the flexible display assembly and protecting the flexible display screen 10 from damage than if a deformable filler material were disposed within the receiving cavity 501.
