Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic structural diagram of a conventional flexible display device. As shown in fig. 1, the bendable display device includes a bendable display panel 10 and a support structure 20 for supporting the bendable display panel 10. The support structure 20 comprises a support membrane 21 and a back plate 22. The support film 21 is disposed between the foldable display panel 10 and the back plate 22. After the thickness of the back plate 22 is compared, when the bendable display panel 10 is bent, the supporting film 21 and the back plate 22 are bent at the same time, so that the bending difficulty of the bendable display device is increased. Meanwhile, after the thickness of the supporting structure 20 is compared, the stress concentration phenomenon of the bendable display panel is obvious in the bending process, and cracks are easily generated in the bendable display panel, so that the conductive wires of the bendable display panel in the bending area are broken, and the reliability of the bendable display panel is reduced.
In view of the above technical problems, embodiments of the present invention provide a supporting structure of a bendable display panel. Fig. 2 is a schematic cross-sectional structural view of a supporting structure of a bendable display panel according to an embodiment of the present invention, and fig. 3 is a schematic structural view of the supporting structure of the bendable display panel according to the embodiment of the present invention. As shown in fig. 2 and 3, the support structure includes a support film 110; the support film 110 includes a bending region 111 and a first non-bending region 112 and a second non-bending region 113 disposed at two sides of the bending region 111; on the side of the supporting film 110 away from the bendable display panel, the first non-bending region 112 and the second non-bending region 113 are provided with a back plate 120, and the bending region 111 is provided with a supporting rod 130 and a first connecting structure 140; the support rod 130 is connected to the back plate 120 by the first connecting structure 140, and the support rod 130 has elastic properties in the axial direction and rigid properties in the transverse direction.
In particular, the support structure is used for supporting the bendable display panel. The axial elasticity of the supporting rod 130 is that the supporting rod 130 has a better elasticity performance in the extending direction thereof, for example, the performance of the supporting rod 130 in the extending direction thereof is similar to the performance of rubber, and has a better elasticity. The transverse rigidity of the support rod 130 is that the support rod 130 has a relatively good rigidity in the tangential direction of the axial direction, for example, the transverse rigidity of the support rod 130 is similar to that of steel, and has a relatively good rigidity. The bending region 111 of the supporting film 110 corresponds to a bending region of the bendable display panel, and the first non-bending region 112 and the second non-bending region 113 of the supporting film 110 correspond to planar regions on two sides of the bending region of the bendable display panel, respectively.
The supporting rod 130 and the first connecting structure 140 are disposed on a side of the supporting film 110 away from the bendable display panel, the supporting rod 130 may have a connector, the first connecting structure 140 may be a hole disposed on the back plate 120, and the connector of the supporting rod 130 is embedded into the first connecting structure 140, so as to form a fixed connection between the back plate 120 and the supporting rod 130. The support rod 130 has elastic properties in the axial direction and rigid properties in the transverse direction. When the supporting rod 130 is connected to the back plate 120 located in the first non-bending region 112 and the back plate 120 located in the second non-bending region 113 through the first connecting structure 140, an included angle between an axial direction of the supporting rod 130 and a direction parallel to the direction from the first non-bending region 112 to the second non-bending region 113 is an acute angle. Therefore, in the bending process of the bendable display panel, the supporting rod 130 is stressed in a direction parallel to the direction in which the first non-bending region 112 points to the second non-bending region 113, at this time, the axial elastic performance of the supporting rod 130 can enable the supporting rod 130 to stretch along the extending direction of the supporting rod 130, the supporting rod 130 disperses the stress generated when the bendable display panel is bent, and the risk of fracture of the bendable display panel is reduced. In addition, when the bendable display panel is in a non-bending state, the back plates 120 on two sides of the bending region 111 extrude towards the bending region 111 to generate pressure on the supporting rod 130, and at the moment, the transverse rigidity of the supporting rod 130 generates a larger shearing force to support the supporting rod 130 and ensure that the supporting rod 130 does not fall down, so that the supporting rod 130 forms a more stable transverse structure, the effect of supporting the bendable display panel by the supporting structure is ensured, and the fracture risk of the bendable display panel is further reduced. Therefore, the supporting rod 130 is arranged to have elastic performance in the axial direction and rigid performance in the transverse direction, so that stress generated when the bendable display panel is bent is relatively dispersed, and the fracture risk of the bendable display panel is reduced. Meanwhile, the stable structure of the support rod 130 can be ensured, and the effect that the support structure supports the bendable display panel is ensured, so that the fracture risk of the bendable display panel is further reduced.
Illustratively, with continued reference to fig. 2 and 3, the bending region 111 is provided with a plurality of support bars 130 and a second connecting structure 150, at least two support bars 130 extend in different directions, and the plurality of support bars 130 are connected by the second connecting structure 150.
Specifically, as shown in fig. 3, at the bending region 111, a plurality of support rods 130 may form a plurality of vias connecting the back plate 120 at both sides of the bending region 111. The same path may also be connected to the back plate 120 at both sides of the bending region 111 by connecting a plurality of support rods 130. The extending directions of the supporting rods 130 in the same passage can be different, so that the stress generated by the supporting rods 130 with different extending directions can be dispersed in different directions when the bendable display panel is bent, the stress concentration phenomenon when the bendable display panel is bent can be better relieved, and the fracture risk of the bendable display panel is reduced. In addition, the plurality of support rods 130 in the same passage are connected by the second connecting structure 150, and the relative positions of the adjacent support rods 130 are fixed. At the display panel non-bending state of can buckling, the backplate 120 of the district 111 both sides of buckling extrudees to the district 111 of buckling, the different horizontal rigidity performance of adjacent bracing piece 130 of extending direction makes different bracing pieces 130 have the effort of interact in second connection structure 150 department, thereby can make the bearing structure including bracing piece 130 and second connection structure 150 have stable transverse structure, guarantee that bracing piece 130 does not fall, thereby can make bearing structure have more stable structure, the effect that bearing structure supported display panel of can buckling has been guaranteed, thereby further reduction display panel's the fracture risk of can buckling.
Optionally, the second connecting structure 150 includes at least two vias 151, and the relative positions of the at least two vias 151 are fixed; the adjacent support bars 130 are relatively fixedly connected through the via holes 151 of the same second connecting structure 150.
With continued reference to fig. 3, a second connecting structure 150 is used to connect adjacent support rods 130. When the support rods 130 connected to the same second connecting structure 150 include only two, the second connecting structure 150 may include two via holes 151, and each via hole 151 is fixedly connected to one support rod 130, so that the relative position of the two support rods 130 connected to the same second connecting structure 150 may be fixed. When the number of the supporting rods 130 connected to the same second connecting structure 150 is four, the second connecting structure 150 may include four via holes 151, and each via hole 151 is fixedly connected to one supporting rod 130, so that the relative position of the four supporting rods 130 connected to the same second connecting structure 150 may be fixed. Fig. 4 is a schematic structural view illustrating a connection between a support rod and a second connecting structure according to an embodiment of the present invention. As shown in fig. 4, the supporting rod 130 is provided with a connector 131, the second connecting structure 150 is provided with a via hole 151, and the connector 131 on the supporting rod 130 can be embedded into the via hole 151, so as to fixedly connect the supporting rod 130 and the second connecting structure 150.
After the relative position of the supporting rod 130 connected with the same second connecting structure 150 is fixed, the bendable display panel can enable the supporting rod 130 connected with the same second connecting structure 150 to have interaction acting force when in a non-bending state, and the supporting rod 130 is guaranteed not to fall down, so that the supporting structure can have a stable transverse structure, and the supporting structure can have a more stable structure. When the bendable display panel is bent or in a bent state, the supporting rods 130 connected with the same second connecting structure 150 disperse the stress generated by bending in different directions, so that the stress concentration phenomenon of the bendable display panel when bent can be better relieved, and the fracture risk of the bendable display panel is reduced.
Preferably, with continued reference to fig. 3, in the first direction X, the plurality of support rods 130 form at least one row of connected polygons 160 via the second connecting structure 150; at least one inner corner connecting line 161 of the polygon 160 is parallel to the first direction X; the first direction X is parallel to the direction in which the first non-bending region points to the second non-bending region.
Specifically, when the support rods 130 form at least one row of polygons 160 through the second connection structures 150, adjacent polygons 160 share one second connection structure 150 in the row of polygons 160. Fig. 5 is a schematic view of a stress analysis of a second connection structure according to an embodiment of the present invention. Fig. 5 is a force analysis diagram of the second connection structure in the dashed box of fig. 3. When the foldable display panel is bent or in a bent state, a stress analysis is performed on the second connecting structure 150 shared by the adjacent polygons 160, and the second connecting structure 150 is subjected to two pairs of four forces in the same straight line and in different directions, namely F1, F2, F3 and F4. That is, at the second connecting structure 150, the supporting rod 130 can decompose the stress generated by bending the bendable display panel in four directions, so that the stress concentration phenomenon generated by bending the bendable display panel can be better alleviated, and the fracture risk of the bendable display panel is reduced. In addition, the force at the second connection structure 150 is analyzed. By decomposing the two forces on the same straight line, it is understood that the force received by the second connecting structure 150 is decomposed into a force in the first direction X, and the force in the direction perpendicular to the first direction X is cancelled out. Therefore, at the second connecting structure 150, the elastic property of the supporting rod 130 in the axial direction can make the supporting rod 130 have a larger recoverable deformation in the first direction X, and recover the deformation when the bendable display panel is in a non-bending state. And the bracing piece 130 transversely has the rigidity performance, and bracing piece 130 has interact's shearing force in the transverse direction, produces supporting role to bracing piece 130, guarantees that bracing piece 130 does not fall for bracing piece 130 has stable transverse structure, and then makes bearing structure have more stable structure, has guaranteed that bearing structure supports the effect of display panel that can buckle, thereby further reduction the fracture risk of display panel that can buckle. Furthermore, at least one inner corner connecting line 161 of a polygon 160 is parallel to the first direction X, such that a force applied at the second connecting structure 150 shared by adjacent polygons 160 can be decomposed into a force parallel to the first direction X. Fig. 6 is a schematic structural diagram of the supporting structure of the flexible display panel provided in fig. 3 when the flexible display panel is bent. As shown in fig. 6, when the foldable display panel is bent, the polygon 160 is stretched toward the back plate 120 at both sides of the bending region 111, and is largely deformed. The axial direction of the supporting rod 130 has elastic performance, so that the deformation of the supporting rod 130 is recovered to be normal when the bendable display panel is in a non-bending state, and the risk of fracture of the supporting rod 130 is reduced. Meanwhile, the transverse rigidity of the supporting rod 130 can generate a larger shearing force to support the supporting rod 130, so that the supporting rod 130 is ensured not to fall, and the supporting structure has a stable transverse structure, namely a more stable structure.
Illustratively, polygon 160 includes a diamond shape; one inner corner connecting line 161 of the rhombus is parallel to the first direction X.
Specifically, when the polygon 160 is a rhombus, one of the inner-angle connecting lines 161 of the rhombus is parallel to the first direction X. Illustratively, a pair of inner angle connecting lines 161 having diamond-shaped inner angles smaller than 90 ° may be made parallel to the first direction X. When the bendable display panel is bent, the adjacent rhombuses share one second connecting structure 150, at the second connecting structure 150, the force of the second connecting structure 150 on the first direction X is larger, and the force on the first direction perpendicular to is smaller, so that the supporting rod 130 can disperse the stress in different directions, and meanwhile, the axial elasticity and the transverse rigidity of the supporting rod 130 are utilized, the fracture risk of the supporting rod 130 is reduced, and the supporting rod 130 has a stable transverse structure.
It should be noted that fig. 3 is merely an exemplary illustration of the support rods 130 forming a diamond shape. In other embodiments, the support rods 130 may form a plurality of diamonds, and the diamonds may be arranged in an array. Fig. 7 is a schematic structural diagram of a supporting structure of another bendable display panel according to an embodiment of the invention. As shown in fig. 7, the support rods 130 of the bending region 111 form a plurality of rhombuses arranged in an array, so that the stress generated when the support rods 130 and the second connecting structure 150 bend the bendable display panel is uniformly dispersed, and the local stress concentration phenomenon of the bending region 111 is avoided. Fig. 8 is a schematic structural diagram of the supporting structure of the flexible display panel provided in fig. 7 when the flexible display panel is bent. As shown in fig. 8, when the foldable display panel is bent or in a bent state, the diamonds are simultaneously stretched toward the back plate 120 at two sides of the bending region 111, resulting in a large deformation.
With continued reference to fig. 7, the portion of the edge of the back plate 120 to which the support rods 130 between the first and second connection structures 140 and 150 are connected forms a triangle.
In particular, the triangle has stability. When the supporting rod 130 between the first connecting structure 140 and the second connecting structure 150 and the part of the edge of the back plate 120 connected thereto form a triangle, the connection between the supporting rod 130 and the back plate 120 is relatively stable, so that the stability of the whole supporting structure can be ensured.
Fig. 9 is a schematic cross-sectional view of a supporting structure of another bendable display panel according to an embodiment of the invention. As shown in fig. 9, the first non-bending region 112 and the second non-bending region 113 are further provided with an organic glue 170, and the back plate 120 is fixedly connected to the support film 110 through the organic glue 170.
Specifically, the organic glue 170 may be an Optically Clear Adhesive (OCA) for bonding the back plate 120 and the support film 110.
With continued reference to fig. 9, the support structure further includes a flexible pad 180; disposed between the support membrane 110 and the support rod 130 and/or the second connection structure 150; the flexible pad 180 serves to relieve friction between the support rod 130 and/or the second connection structure 150 and the support membrane 110.
Specifically, the supporting membrane 110 has a low stiffness, and the supporting rod 130 and the second connecting structure 150 have a higher stiffness than the supporting membrane 110. When the bendable display panel is switched between the bent state and the non-bent state, the flexible pad 180 can relieve the friction force of the support rod 130 acting on the support film 110 in the process that the support rod 130 is stretched along the first direction X, so as to reduce the probability that the support film 110 is scratched by the friction force.
On the basis of the technical schemes, the supporting rod is made of rubber/carbon fiber composite materials, and the extending direction of carbon fibers is perpendicular to the axial direction of the supporting rod.
Specifically, the rubber/carbon fiber composite material may be made by embedding carbon fibers in rubber. The rubber has good elastic properties. The carbon fiber is added on the basis of the elastic property of the rubber, so that the extending direction of the carbon fiber is perpendicular to the axial direction of the supporting rod, and the transverse rigidity property of the rubber/carbon fiber composite material can be increased, thereby realizing the characteristics that the supporting rod has the elastic property in the axial direction and has the rigidity property in the transverse direction. Meanwhile, the elastic modulus thereof is larger than that of rubber. For example, the elastic modulus of rubber is 0.0000784x10^5MPa, and the elastic modulus of rubber/carbon fiber composite material is 2.1x10^5 MPa.
The embodiment of the invention also provides a display module. Fig. 10 is a schematic structural diagram of a display module according to an embodiment of the present invention. As shown in fig. 10, the display module includes a flexible display panel 101 and a supporting structure 102 of the flexible display panel according to any embodiment of the present invention. The support structure 102 of the bendable display panel is disposed on the backlight side of the bendable display panel 101.
Specifically, the support structure 102 of the bendable display panel is disposed on the backlight side of the bendable display panel 101, and has a supporting function on the bendable display panel 101. Because the structure of the support structure 102 of the bendable display panel is the support structure 102 of the bendable display panel provided by any embodiment of the invention, the support structure 102 of the bendable display panel provided by any embodiment of the invention has the beneficial effects, so that the stress generated when the bendable display panel is bent can be relatively dispersed, and the risk of fracture of the bendable display panel is reduced. Meanwhile, the stability of the bendable display panel supported by the supporting structure can be guaranteed, so that the fracture risk of the bendable display panel is further reduced.
