The term "include" or "comprise" and similar terms are intended to mean that the element or object before "include" or "comprise" covers the elements or objects or equivalents listed after "include" or "comprise," without excluding other elements or objects.

[0047] FIG. 1 is a schematic structural diagram of a display device according to some embodiments of the present disclosure. As shown in FIG. 1, the display device includes a flexible display panel 100, a support structure, a guide rail 300 (shown in FIG. 15), and a scroll 200. The flexible display panel 100 includes a planar display portion 101 and a rollable display portion 102, and the flexible display panel 100 has a display surface and a non-display surface that are opposite to each other.

[0048] The support structure includes a non-light-emitting side that is disposed on and always distributed on the rollable display portion 102 of the flexible display panel 100. The scroll 200 is disposed on the non-display surface of the flexible display panel 100, and the rollable display portion 102 of the flexible display panel 100 is scrollably wound on the scroll 200. When the rollable display portion 102 of the flexible display panel 100 slides along the scroll 200, the support structure can effectively support the rollable display portion 102 of the flexible display panel 100 that is scrollably wound on the scroll 200, to prevent the flexible display panel 100 from a greater extent of defects such as warping during the sliding and rolling process. Therefore, a better overall flatness of the flexible display panel 100 is ensured, thereby ensuring a better display effect of the display device.

[0049] FIG. 2 is a schematic diagram of a support structure according to some embodiments of the present disclosure, and FIG. 3 is a top view of the support structure shown in FIG. 2. As shown in FIG. 2 and FIG. 3, the support structure includes a plurality of first support members la, and the plurality of first support members la are arranged in parallel.

The two sliding parts 20 are respectively disposed at two ends of the support strip 10, and at least a portion of the sliding part 20 extends beyond the support strip 10 in the length direction x of the support strip 10. The support strip 10 and the sliding part 20 are made of different materials. The side of the support strip 10 away from a sliding base is coupled to the flexible display panel to play a function of supporting the flexible display panel.

[0051] FIG. 4 is a schematic structural diagram of a first support member according to some embodiments of the present disclosure. As shown in FIG. 4, in the embodiments of the present disclosure, a first connecting structure 11 is disposed at each of the two ends of the support strip 10, and the sliding part 20 includes a second connecting structure 22. The first connecting structure 11 and the second connecting structure 22 are recessed and protruding structures matching each other, and the support strip 10 and the sliding part 20 are connected by the first connecting structure 11 and the second connecting structure 22. The protrusion structure in first connecting structure and the recessed structure in second connecting structure can increase the connecting area between the support strip and the sliding part, thereby achieving a reliable connection between the support strip and the sliding part to form the support member.

[0052] In the embodiments of the present disclosure, as shown in FIG. 4, the sliding part 20 includes a sliding base 23 and a columnar protrusion 21, and the orthographic projection of the sliding base 23 on a first surface of the support strip 10 is within the first surface of the support strip 10. The first surface of the support strip 10 is a surface on which the first connecting structure 11 is located. In the length direction x of the support strip 10, the columnar protrusion 21 is disposed on the side of the sliding base 23 away from the support strip 10. The sliding base 23 bears the second connecting structure 22 and the columnar protrusion 21.

[0053] In the embodiments of present disclosure, as shown in FIG. 4, the dimension al of the base 23 in the length direction x of the support strip 10 ranges from 0.3 mm to 3 mm, e.g., 0.3 mm, 0.8 mm, 1.5 mm, 2 mm, and 3 mm.

[0054] In the embodiments of the present disclosure, as shown in FIG. 4, the ratio of the dimension a2 of the sliding base 23 in the width direction y of the support strip 10 to the width of the support strip 10 ranges from 0.5 to 1.5. For example, the ratio is 0.8 to 1.2. Exemplarily, the ratio is 1.

[0055] Exemplarily, in the support member shown in FIG. 4, the first connecting structure 11 includes a protruding structure in the shape of a dovetail table, and the second connecting structure 22 includes a recessed structure of a corresponding shape.

[0056] FIG. 5 is a side view of the first support member shown in FIG. 4. As shown in FIG. 4 and FIG. 5, the protruding structure has a first surface 110 and a second surface 120 opposite to each other and a sidewall 130 connecting the first surface 110 and the second surface 120. The first surface 110 is connected to the bearing surface 140 of the protruding structure. The angle a between the second surface 120 and the sidewall 130 ranges from 10° to 80°, e.g., 30° to 60°. The bearing surface 140 of the protruding structure is a surface connecting the protruding structure and the first connecting structure including the protruding structure.

[0057] FIG. 6 is a schematic structural diagram of another first support member according to some embodiments of the present disclosure. The support member shown in FIG. 6 differs from the first support member shown in FIG. 4 in that the first connecting structure 11 includes a recessed structure in the shape of a dovetail groove and the second connecting structure 22 includes a protruding structure in the shape of a dovetail table.

[0058] The dovetail table is a special prismatic structure, the cross-section of which is in the shape of an isosceles trapezoid. The angle a is an angle between the bottom edge and a sidewall of the isosceles trapezoid.

[0059] In some embodiments, in the case that the first connecting structure 11 includes a recessed structure, the recessed structure passes through the support strip or does not pass through the support strip.

[0060] FIG. 7 is a side view of the first support member shown in FIG. 6. In combination with FIG. 6 and FIG. 7, similarly, the angle a between the second surface 120 and the sidewall 130 of the protruding structure ranges from 10° to 80°, e.g., 30° to 60°. The angle a is set to increase the bonding force between the protruding structure and the recessed structure.

[0061] In the embodiments of the present disclosure, as shown in FIG. 5 and FIG. 7, the dimension hl of the protruding structure in the thickness direction z of the support strip 10 ranges from 0.1 mm to 1 mm, and the dimension h2 of the recessed structure in the thickness direction z of the support strip 10 ranges from 0.1 mm to 1 mm, e.g., 0.1 mm, 0.5 mm, 0.8 mm, and 1 mm. The protruding structure and the recessed structure are set to have such dimensions to ensure the connecting strength of the support strip and the sliding part under the premise that the overall volume of the display device is not affected.

[0062] FIG. 8 is a schematic structural diagram of still another first support member according to some embodiments of the present disclosure. The first support member shown in FIG. 8 differs from the support member shown in FIG. 4 in that the first connecting structure 11 includes a protruding structure in the shape of a truncated pyramid and the second connecting structure 22 includes a recessed structure.

[0063] FIG. 9 is a schematic structural diagram of still another first support member according to some embodiments of the present disclosure. The first support member shown in FIG. 9 differs from the support member shown in FIG. 4 in that the second connecting structure 22 includes a protruding structure in the shape of a circular truncated cone and the first connecting structure 11 includes a recessed structure.

[0064] It should be noted that, in the embodiments shown in FIG. 8 and FIG. 9, the positions of the protruding structure and the recessed structure is exchangeable, that is, the first connecting structure 11 includes a recessed structure and the second connecting structure 22 includes a protruding structure.

[0065] FIG. 4 to FIG. 9 are exemplarily illustrated by taking an example in which the first connecting structure 11 and the second connecting structure 22 include one protruding structure or recessed structure. In other embodiments, the number of the protruding structures and the number of the recessed structures may be set based on needs, for example, two, three, or the like.

[0066] In the case that a plurality of protruding structures or a plurality of recessed structures are provided, the plurality of protruding structures are of the same shape and have the same dimension. For example, in the support member shown in FIG. 10, the second connecting structure 22 includes two protruding structures in the shape of a cylinder, and the first connecting structure 11 includes two recessed structures.

[0067] Alternatively, in the case that a plurality of protruding structures or a plurality of recessed structures are provided, the plurality of protruding structures are of different shapes. For example, in the support member shown in FIG. 11, the second connecting structure 22 includes two protruding structures, which are in the shape of a cylinder and a circular truncated cone, respectively, and the first connecting structure 11 includes two recessed structures.

[0068] In other possible implementations, the first connecting structure 11 includes at least one protruding structure and at least one recessed structure, and the second connecting structure 22 includes the corresponding at least one recessed structure and at least one protruding structure.

[0069] In the embodiments of the present disclosure, the protruding structure is a dovetail table (as shown in FIG. 4 and FIG. 6), a truncated pyramid (as shown in FIG. 8), a circular truncated cone (as shown in FIG. 9 and FIG. 11), a cylinder (as shown in FIG. 10 and FIG. 11) or other prisms. The center line of the protruding structure is perpendicular to the length direction x of the support strip 10 and the width direction y of the support strip 10. The protruding structures of these shapes can increase the bonding force between the protruding structure and the recessed structure. Therefore, the bonding between the protruding structure and the recessed structure is more reliable, and the support strip and the sliding part are not easy to separate from each other.

[0070] The shape of the protruding structure is not limited in the embodiments of the present disclosure, and may be selected based on actual needs. For example, the protruding structure is in the shape of a prism, or the like.

[0071] In some embodiments, the protruding structure has a plurality of sidewalls, and the plurality of sidewalls are smoothly connected. As shown in FIG. 8, the protruding structure is in the shape of a truncated pyramid, and the sidewalls 130 are smoothly connected.

[0072] In the embodiments of the present disclosure, in the case that a plurality of protruding structures and a plurality of recessed structures, the plurality of protruding structures are spaced apart in the length direction x of the support strip 10, and the distance between two adjacent protruding structures is greater than or equal to 0.2 mm. In the length direction x of the support strip and the width direction y of the support strip, the plurality of protruding structures are disposed within the range of the sliding base 23. As shown in FIG. 10 or FIG. 11, two protruding structures are spaced apart in the length direction x of the support strip.

[0073] FIG. 12 is a schematic structural diagram of a first support member including a limiting member according to some embodiments of the present disclosure. As shown in FIG. 12, the sliding part 20 further includes a limiting member 24. The limiting member 24 includes a connecting portion 241 and a sliding portion 242, and the connecting portion 241 connects the sliding portion 242 to the sliding base 23 to fix the limiting member 24 on the sliding base 23. In the width direction y of the support strip 10, two ends of the sliding portion 242 of the limiting member 24 are in the shape of an arc that is bent towards the same direction.

[0074] In combination with FIG. 2, in the support structure including a plurality of first support members la, the limiting member 24 is configured to limit the movement of the first support members la in the width direction y of the support strip 10. In the length direction x of the support strip 10, the limiting member 24 and the columnar projection 21 are disposed on the same side of the sliding base 23.

[0075] FIG. 13 is a top view of a first support member according to some embodiments of the present disclosure. As shown in FIG. 13, the support strip 10 is a plate-like structure in the shape of a long strip, and the support strip 10 has no hollowed-out structures.

[0076] In the embodiments of the present disclosure, at least one of the support strip 10 and the sliding part 20 is made of a non-metal material, that is, at least one of the support strip 10 and the sliding part 20 is non-metal structure member. In the relate art, the support strip and the sliding part are both made of a metal material, and the support member is heavy. Since the density of the non-metal material is less than the density of the metal material, the weight of the support member can be reduced, which facilitates the portability and use of the display device.

[0077] Exemplarily, the support strip 10 is made of a carbon fiber material, and the support strip 10 is a carbon fiber structure member. The density of the carbon fiber material is less than the density of the metal material, which can greatly reduce the weight of the support strip.

[0078] Exemplarily, the support strip 10 includes at least three carbon fiber material layers that are sequentially stacked, and two adjacent carbon fiber material layers of the at least three carbon fiber material layers have different carbon fiber direction orientations. Adjacent carbon fiber material layers having different carbon fiber direction orientations can meet the requirement on the strength of the support strip.

[0079] Exemplarily, in the at least three carbon fiber material layers, the carbon fiber direction orientation of a carbon fiber material layer disposed in an odd number layer is a first carbon fiber direction orientation, the carbon fiber direction orientation of a carbon fiber material layer disposed in an even number layer is a second carbon fiber direction orientation, and the first carbon fiber direction orientation and the second carbon fiber direction orientation intersect, which can increase the strength of the support strip as much as possible.

[0080] Exemplarily, the support strip 10 includes at least three carbon fiber material layers that are sequentially stacked, and the first carbon fiber direction orientation and the second carbon fiber direction orientation are perpendicular to each other, which can increase the strength of the support strip as much as possible.

[0081] In some embodiments, the sliding part 20 is made of metal, a resin material, or plastic, that is, the sliding part 20 is a metal structure member, a resin structure member, or a plastic structure member. When the sliding part 20 is made of such materials, sufficient hardness of the sliding part 20 can be ensured, which can facilitate the matching between the sliding part 20 and the sliding rail.

[0082] Exemplarily, in the case that the support strip is made of the carbon fiber material, the first connecting structure 11 is a protruding structure, and the second connecting structure 22 is a recessed structure, the filling rate of resin in the recessed structure is greater than 90%, which can increase the bonding force between the first connecting structure and the second connecting structure. The recessed structure made of the resin material has bubbles therein, and the filling ratio here is the ratio of the volume of the resin material to the total volume of the resin material and the bubbles. The second connecting structure here is also referred to as a glue-gripping structure, and the "glue" refers to the resin in the carbon fiber material.

[0083] The support strip 10 is made of the carbon fiber material (with a density of 1.78 g), the sliding part 20 is made of stainless steel (sus316), and the support strip 10 and the sliding part 20 are connected by means of carbon fiber hot pressing, thereby forming the support member, and this support member is compared with a support member totally made of stainless steel (sus316). The mass of the support member in the embodiments of the present disclosure is reduced by 71%, which greatly reduces the weight of the support structure. In addition, a drawing force test is conducted on the support member provided in the embodiments of the present disclosure, and the support member can withstand a drawing force of more than 1 kgf. It can be seen that the connection between the support strip 10 and the sliding part 20 is reliable.

[0084] Exemplarily, as shown in FIG. 13, the width a3 of the support strip 10 ranges from 0.5 mm to 100 mm. The support strip having such a width ensures that the support strip can provide sufficient support. Here, the width a3 of the support strip 10 is less than or equal to 100 mm, and the support strip 10 is more suitable for application to small-sized mobile terminal products. When the support strip 10 is applied to large-sized products, the width a3 of the support strip 10 is larger and is not limited to be less than or equal to 100 mm.

[0085] Exemplarily, referring to FIG. 3 again, in the support structure, the ratio of the distance a4 between two adjacent support strips 10 to the width a3 of the support strip 10 ranges from 0.5 to 1.5, e.g., 0.8 to 1.2. Exemplarily, the ratio of the distance a4 between two adjacent support strips 10 to the width a3 of the support strip 10 is 0.9, 1.0, or 1.1.

[0086] FIG. 14 is a plane view of another support structure according to some embodiments of the present disclosure. As shown in FIG. 14, the support structure shown in FIG. 14 differs from the support structure shown in FIG. 3 in that the support strip 10 in FIG. 14 is provided with at least two strip grooves 12, the strip groove 12 passes through the support strip 10 in the thickness direction z of the support strip 10, the length direction of the strip groove 12 is the same as the length direction x of the support strip 10, and the at least two strip grooves 12 are arranged along the length direction x of the support strip 10. The strip grooves are provided to further reduce the weight of the support member.

[0087] Exemplarily, the length of the strip groove 12 is less than a half of the length of the support strip 10 and is greater than 0. The strip groove 12 having such a length range can reduce the weight of the support strip, and meanwhile, the support strip 10 will not be insufficiently supportive during use because the sliding groove is too long to result in bending, deformation and the like, thereby ensuring the display effect of the display device.

[0088] In some embodiments, the width of the strip groove 12 is greater than 0.2 mm and less than the width of the support strip 10.

[0089] Exemplarily, as shown in FIG. 3 and FIG. 14, the support structure further includes a second support member lb. The width of the support strip 10 of the second support member lb is greater than the width of the support strip 10 of the first support member la. Other features of the second support member lb are substantially the same as those of the first support member. The second support member lb is arranged in parallel with the plurality of first support members la, and the second support member lb is disposed on a side of the plurality of first support members la in the arrangement direction of the plurality of first support members la.
