In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0044] The orientation terms appearing in the following description are all the directions shown in the figures and do not limit the specific structure of the embodiments of the present application. In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "mounted", "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected or indirectly connected.

[0045] For a better understanding of the present application, the following will combine Figures 1 to 8 to describe in detail the support structure and the display device of the embodiments of the present application.

[0046] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic side view structure diagram of a display device provided by an embodiment of the present application in one state; Figure 2 is a schematic side view structure diagram of a display device provided by an embodiment of the present application in another state.

[0047] According to an embodiment of the first aspect of the present application, a display device is provided. The display device includes a flexible display panel 100 and a support structure 200, and the support structure 200 is used to provide support to the flexible display panel 100.

[0048] The display device in the embodiments of the present application includes, but is not limited to, devices with a display function such as mobile phones, personal digital assistants (PDAs), tablet computers, e-books, televisions, access control devices, smart landline phones, and consoles.

[0049] In some alternative embodiments, the flexible display panel 100 can be deformably arranged. The support structure 200 can be bendably arranged. As Figure 1 shown, in the bent state, at least part of the flexible display panel 100 is bent along the support structure 200 to its back side, so at least part of the flexible display panel 100 overlaps in the second direction. In the unfolded state, the support area of the support structure 200 on the same side increases, thereby increasing the display area of the display device. For example, when the support member changes from the state shown in Figure 1 to the state shown in Figure 2 , the size of the display device in the first direction X increases, and the displayable area of the display device increases.

[0050] Please refer to Figures 3 to 5 , Figure 3 which is a schematic structural diagram of a support structure 200 provided by the embodiments of the present application, Figure 4 is Figure 3 the bottom view of Figure 5 which is a partial structural schematic diagram of a support structure 200 provided by the embodiments of the present application in the bent state, Figure 6 which is a partial structural schematic diagram of a support structure 200 provided by the embodiments of the present application in the unfolded state.

[0051] As Figures 2 to 6As shown in the figure, an embodiment of the present application provides a support structure 200 for a flexible display panel 100. The support structure 200 includes a main support member 10, a flexible support member 20, and an auxiliary support member 30. The flexible support member 20 is used to support the flexible display panel 100. The flexible support member 20 includes a fixing portion 21 and a folding portion 22 located on at least one side of the fixing portion 21. The fixing portion 21 is fixed to the main support member 10. The fixing portion 21 includes a first support surface 21a for supporting the flexible display panel 100. The folding portion 22 includes a second support surface 22a for supporting the flexible display panel 100. The folding portion 22 is bendably disposed relative to the fixing portion 21 so that the second support surface 22a has a bent state and an unfolded state. In the bent state, at least a part of the plane where the second support surface 22a is located intersects with the plane where the first support surface 21a is located. In the unfolded state, the plane where the second support surface 22a is located is coplanar with the plane where the first support surface 21a is located. The auxiliary support member 30 is disposed on the flexible support member 20 and is used to support the folding portion 22. One end of the auxiliary support member 30 is movably connected to the fixing portion 21 or the main support member 10, and the other end of the auxiliary support member 30 is movably connected to the folding portion 22. The auxiliary support member 30 is configured to shorten as the flexible support member 20 bends, or elongate as the flexible support member 20 unfolds.

[0052] When the support structure 200 is used in a display device, the flexible display panel 100 can be fixed to the side of the flexible support member 20 away from the main support member 10, so that the flexible support member 20 can drive the flexible display panel 100 to change between the bent state and the unfolded state.

[0053] In the bent state, the first support surface 21a intersects with at least a part of the second support surface 22a, or a part of the second support surface 22a intersects with the first support surface 21a, and the other part of the second support surface 22a is stacked with the first support surface 21a along the second direction. In the unfolded state, the coplanarity of the first support surface 21a and the second support surface 22a is not a strictly coplanar in the geometric sense. As long as the first support surface 21a and the second support surface 22a are substantially coplanar, it does not affect the overall display of the flexible display panel 100.

[0054] In the support structure 200 of the embodiment of the present application, the support structure 200 includes a main support member 10, a flexible support member 20, and an auxiliary support member 30. The fixing portion 21 of the flexible support member 20 is connected to the main support member 10, and the folding portion 22 of the flexible support member 20 is bendable relative to the fixing portion 21, so that the second support surface 22a and the first support surface 21a can be coplanar or intersect, thereby enabling the flexible display panel 100 disposed on the flexible support member 20 to be unfolded or folded, facilitating large-size display and small-size storage of the flexible display panel 100. The auxiliary support member 30 is used to support the folding portion 22, and the auxiliary support member 30 is configured to shorten as the flexible support member 20 is bent, or elongate as the flexible support member 20 is unfolded. In the unfolded state, the length of the auxiliary support member 30 is relatively large, and it can provide support to the folding portion 22, improving the structural strength of the flexible support member 20 in the unfolded state so that the support structure can provide stable support to the flexible display panel 100.

[0055] The main support member 10 is used to provide stable support to the flexible display panel 100, and the main support member 10 is used as a carrier of the flexible support member 20. The fixing portion 21 can be fixed to one side of the main support member 10. In the unfolded state, the folding portion 22 and the fixing portion 21 are located on the same side of the main support member 10. In the bent state, at least part of the folding portion 22 and the fixing portion 21 are disposed on both sides of the main support member 10.

[0056] Optionally, the main support member 10 includes a first surface 11 and a second surface 12 oppositely disposed along the second direction Z. The fixing portion 21 can be fixed to the first surface 11. In the bent state, at least part of the folding portion 22 is attached to the second surface 12.

[0057] Optionally, the main support member 10 further includes an arc-shaped support surface 13 connecting the first surface 11 and the second surface 12 and located on both sides of the first surface 11 and the second surface 12 in the first direction X. The folding portion 22 can be bent along the arc-shaped support surface 13 to the second surface 12.

[0058] Optionally, the main support member 10 further includes a first side wall 14 and a second side wall 15 disposed on both sides of the first surface 11 and the second surface 12 along the third direction Y. The first side wall 14 and the second side wall 15 can protrude from the first surface 11 to provide limitation to the fixing portion 21 and / or the flexible display panel 100 located on the fixing portion 21, and the first side wall 14 and the second side wall 15 can also protrude from the second surface 12 to provide limitation to at least part of the folding portion 22 in the bent state.

[0059] A receiving space can be provided inside the main support member 10 to receive components such as control devices.

[0060] There are various ways to arrange the flexible support member 20. The flexible support member 20 can be a flexible steel plate, so that the flexible support member 20 has good support performance and deformation performance.

[0061] The number of the folding portions 22 can be one or more. The folding portions 22 can be arranged on one side of the fixing portion 21 in the first direction X. In this embodiment, the number of the folding portions 22 is two, and the two folding portions 22 are respectively arranged on both sides of the fixing portion 21 in the first direction X. By arranging the two folding portions 22, the support structure 200 can be unfolded and folded on both sides, which can enrich the functions of the support structure 200. When the support structure 200 is used for a display device, the use experience of the display device can also be improved.

[0062] There are various ways to arrange the auxiliary support member 30. For example, the auxiliary support member 30 includes an elastic material, or the auxiliary support member 30 is a structural member with an elastic restoring force, or the auxiliary support member 30 is a damping member or a sliding member, as long as the auxiliary support member 30 can shorten as the flexible support plate 20 bends and elongate as the flexible support plate 20 unfolds.

[0063] Optionally, the auxiliary support member 30 includes a first branch 31 and a second branch connected to each other. The first branch 31 is rotatably connected to the fixing portion 21 or the main body support member 10 away from the second branch 32, and one end of the second branch 32 away from the first branch 31 is rotatably connected to the folding portion 22, so that when the folding portion 22 is converted between the bent state and the unfolded state, the first branch 31 and the second branch 32 can move away from or close to each other.

[0064] In these alternative embodiments, the first branch 31 and the second branch 32 are connected to each other. In the unfolded state, the first branch 31 and the second branch 32 move away from each other, which can increase the total size of the first branch 31 and the second branch 32, so that part of the second branch 32 can provide support for the folding portion 22, improve the structural strength of the flexible support member 20 in the unfolded state, and enable the support structure 200 to provide stable support for the flexible display panel 100.

[0065] Optionally, the first branch 31 and the second branch 32 are relatively movably arranged.

[0066] Optionally, one end of the first branch 31 is rotatably connected to the main body support 10, the other end of the first branch 31 is movably connected to the second branch 32, and one end of the second branch 32 away from the first branch 31 is rotatably connected to the folding part 22. In the unfolded state, the first branch 31 and the second branch 32 are away from each other, the first branch 31 and the second branch 32 are distributed along the first direction X, and the second branch 32 is used to support the folding part 22. In the process of changing from the unfolded state to the bent state, the first branch 31 and the second branch 32 approach each other, and the first branch 31 rotates a preset angle relative to the main body support 10, and the second branch 32 rotates a preset angle relative to the folding part 22. When a part of the folding part 22 is attached to the second surface 12, the first branch 31 and the second branch 32 are inclined relative to the flexible display panel 100.

[0067] There are various ways to rotatably connect one end of the first branch 31 to the main body support 10. For example, one end of the first branch 31 and the main body support 10 are ball-hinged to each other. An articulated ball is provided at one end of the first branch 31, and an articulated part is provided on the main body support 10. The articulated part is used to accommodate the articulated ball, so that the first branch 31 is rotatably arranged relative to the main body support 10. Alternatively, a first connecting ring is provided on the main body support 10, a second connecting ring is provided at one end of the first branch 31, and a rotating shaft passes through the first connecting ring and the second connecting ring, so that the first branch 31 can rotate relative to the support column through the rotating shaft.

[0068] There are various ways to rotatably connect one end of the second branch 32 to the folding part 22. For example, as described above, one end of the second branch 32 and the folding part 22 can also be ball-hinged to each other, or the second branch 32 and the folding part 22 can also be connected to each other by a rotating shaft.

[0069] Please refer to Figures 5 to 7 , Figure 7 which is a schematic structural diagram of a support structure 200 provided by an embodiment of the present application from another perspective in the unfolded state.

[0070] In some embodiments, as Figures 5 to 7 shown, the support structure 200 further includes a reset member 33. The reset member 33 is arranged between the first branch 31 and the second branch 32, and the reset member 33 is used to provide a force for the first branch 31 and the second branch 32 to move away from each other in the unfolded state.

[0071] In these alternative embodiments, by providing a reset member 33 between the first branch 31 and the second branch 32, in the deployed state, the reset member 33 can provide a force that moves the first branch 31 and the second branch 32 away from each other, such that the second branch 32 has a tendency to move away from the first branch 31, and the second branch 32 can provide more stable support to the folding portion 22. When the folding portion 22 changes from the deployed state to the bent state, the second branch 32 and the first branch 31 move closer to each other, and the reset member 33 can contract and deform using its own elasticity without affecting the relative movement of the second branch 32 and the first branch 31 towards each other.

[0072] There are various ways to arrange the reset member 33. For example, the reset member 33 is a telescopic spring. In the deployed state, the telescopic spring has a tendency to extend, thereby providing a force that moves the first branch 31 and the second branch 32 away from each other. In other embodiments, the reset member 33 can also be a telescopic rod, such as a hydraulic telescopic rod or an electrically controlled telescopic rod. By electrically controlling the extension amount of the reset member 33, in the deployed state, the reset member 33 can provide support to the folding portion 22.

[0073] There are various ways to arrange the relative movement of the first branch 31 and the second branch 32. In some alternative embodiments, one of the first branch 31 and the second branch 32 includes a first sliding member 301, and the other includes a second sliding member 302 that is movable along the first sliding member 301. The first sliding member 301 and the second sliding member 302 are arranged to match each other, and the relative movement of the first branch 31 and the second branch 32 is achieved by the movement of the second sliding member 302 within the first sliding member 301.

[0074] In the embodiments of the present application, an example is given where the first branch 31 includes the first sliding member 301 and the second branch 32 includes the second sliding member 302. In other embodiments, it is also possible that the second branch 32 includes the first sliding member 301 and the first branch 31 includes the second sliding member 302.

[0075] Optionally, the first sliding member 301 includes an abutting portion 311 and a slide rail 312 connected to the abutting portion 311 on one side in the first direction X. The second sliding member 302 includes a main body portion 321 and a sliding portion 322 located on one side of the main body portion 321 in the third direction Y. The sliding portion 322 is located within the slide rail 312 and is movably arranged relative to the slide rail 312 along the first direction X. The reset member 33 abuts between the abutting portion 311 and the main body portion 321.

[0076] In these alternative embodiments, the sliding part 322 moves along the slide rail 312, and the reset part 33 abuts between the abutting part 311 and the main body part 321 to provide a separating force to the first sub - part 31 and the second sub - part 32. By arranging the slide rail 312 on one side of the abutting part 311 and the sliding part 322 on one side of the main body part 321, without affecting the first sub - part 31 and the second sub - part 32, the abutting part can abut between the first sub - part 31 and the second sub - part 32, which can simplify the structure of the auxiliary support 30.

[0077] Optionally, a rotating part is provided at one end of the main body part 321 away from the first sliding part 301. One of the abutting part 311 and the rotating part is rotatably connected to the main body support 10, and the other is rotatably connected to the folding part 22.

[0078] There are various ways to arrange the slide rail 312 and the sliding part 322. In some embodiments, the two slide rails 312 are arranged at intervals along the third direction Y on the same side of the abutting part 311. The two sliding parts 322 are respectively arranged on both sides of the main body part 321 in the third direction Y. Each sliding part 322 is located on each slide rail 312, and the reset part 33 is located between the two slide rails 312.

[0079] In these alternative embodiments, by providing two slide rails 312 and arranging the reset part 33 between the two slide rails 312, the forces on the first sub - part 31 and the second sub - part 32 are more balanced, and the first sub - part 31 and the second sub - part 32 can slide relative to each other stably.

[0080] There are various ways to arrange the slide rail 312. For example, the slide rail 312 includes two side walls arranged opposite to each other along the second direction Z, a bottom wall connecting the two side walls, and an opening opposite to the bottom wall. The openings of the two slide rails 312 are arranged opposite to each other, so that the sliding parts 322 located on both sides of the main body part 321 can extend into the two slide rails 312 from the openings of the two slide rails 312.

[0081] There are various ways to arrange the sliding part 322. For example, the thickness of the sliding part 322 is less than the thickness of the main body part 321, so that the main body part 321 can provide a limit to the side wall of the slide rail 312, and the side wall can also move along the surface of the main body part 321 protruding from the sliding part 322.

[0082] In some alternative embodiments, the first sub - part 31 further includes a guide rod 313. The guide rod 313 is connected to the abutting part 311 and arranged side by side with the slide rail 312 along the third direction Y. The reset part 33 is sleeved on the guide rod 313. The second sub - part 32 further includes a receiving cavity. The receiving cavity is arranged in the main body part 321 and used to receive the guide rod 313, so that when the first sub - part 31 and the second sub - part 32 approach each other, the guide rod 313 can extend into the receiving cavity.

[0083] In these optional embodiments, by providing a guide rod 313 on the first sub-portion 31, the reset member 33 can move along the guide rod 313, and the guide rod 313 can provide guidance for the reset member 33. An accommodating cavity is provided on the main body 321, and when the first sub-portion 31 and the second sub-portion 32 are close to each other, the guide rod 313 moves toward the second sub-portion 32 and can be accommodated in the accommodating cavity, so as to avoid the positions of the guide rod 313 and the second sub-portion 32 interfering with each other and affecting the mutual movement of the first sub-portion 31 and the second sub-portion 32.

[0084] One group of auxiliary support members 30 may be provided between the same folding portion 22 and the fixed portion 21, or multiple groups of auxiliary support members 30 may be provided between the same folding portion 22 and the fixed portion 21, more than two auxiliary support members 30 may be distributed at intervals on the same folding portion 22 in the third direction Y, or more than two auxiliary support members 30 may be provided at intervals between the main support member 10 and the same folding portion 22 along the third direction Y. By providing multiple auxiliary support members 30, multiple auxiliary support members 30 can provide better support to the folding portion 22, thereby ensuring the structural strength of the flexible support member 20 in the unfolded state.

[0085] In this embodiment, when there are two folding parts 22, there are four auxiliary support members 30, and each folding part 22 is provided with two auxiliary support members 30 spaced apart along the third direction Y to ensure that the forces on the two folding parts 22 are more balanced.

[0086] See also Figure 8 , Figure 8 It is a structural schematic diagram of a flexible support member 20 of a support structure 200 provided in an embodiment of the present application.

[0087] In some optional embodiments, such as Figure 8 As shown, in the direction away from the fixing portion 21, the folding portion 22 includes a bending section 221 and a straight section 222 distributed in sequence, and the bending section 221 can be bent and deformed so that the folding portion 22 can be bent so that the straight section 222 is located on the side of the main support 10 away from the fixing portion 21.

[0088] In these optional embodiments, the folding portion 22 includes two parts, namely a bent section 221 and a straight section 222. In the bent state, the bent section 221 is bent and deformed so that the straight section 222 is located on the second surface 12. In the unfolded state, the bent section 221 is in a straight state, so that the folding portion 22 and the fixing portion 21 are coplanar.

[0089] When the folding portion 22 includes a straight section 222 and a bent section 221 , one end of the second section 32 is rotatably connected to the straight section 222 to prevent the second section 32 from being connected to the bent section 221 and affecting its bending.

[0090] In some alternative embodiments, the bent section 221 includes a plurality of support bars 221a that are spaced apart along the direction from the fixed portion 21 to the folding portion 22. Since there are gaps between two adjacent support bars 221a, the folding portion 22 is more likely to be bent in this area. The plurality of support bars 221a can be interconnected using the flexible display panel 100.

[0091] In some other embodiments, as Figure 9 shown, the bent section 221 includes a plurality of grooves 221b that are arranged side by side and spaced apart along the direction from the fixed portion 21 to the folding portion 22. By forming the grooves 221b on the folding portion 22, the structural strength within the bent section 221 of the folding portion 22 can be reduced, making the folding portion 22 more likely to be bent at the bent section 221.

[0092] There are various ways to set the grooves 221b. For example, the grooves 221b can be formed by bending the folding portion 22 itself along a wavy path, or the thickness of the folding portion 22 can be locally thinned to form the grooves 221b.

[0093] In some alternative embodiments, a fixing member (not shown in the figure) is provided on the main body support 10. The fixing member is used to fix at least a part of the folding portion 22 to the side of the main body support 10 facing away from the fixed portion 21 in the bent state. The fixing member includes a magnetic attraction member or a snap member.

[0094] In these alternative embodiments, by providing the fixing member on the main body support 10, when a part of the folding portion 22 is bent to the second surface 12, for example, when the straight section 222 of the folding portion 22 is bent to the second surface 12, the fixing member can fix the straight section 222 to the second surface 12, improving the stability of the relative positions among the folding portion 22, the fixed portion 21, and the main body support 10 in the bent state.

[0095] The fixing member can be a magnetic attraction member, which provides a magnetic attraction force to the folding portion 22 to fix a part of the folding portion 22 to the second surface 12. Alternatively, the fixing member can include a snap member. When the straight section 222 is bent to the second surface 12, the straight section 222 can be snapped into the fixing member to ensure the stability of the relative positions among the straight section 222, the fixed portion 21, and the main body support 10.

[0096] Although the present application has been described with reference to the preferred embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in each embodiment can be combined in any way. The present application is not limited to the specific embodiments disclosed in the text, but includes all technical solutions that fall within the scope of the claims.
