[0038] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0040] The applicant found that in the prior art, when the foldable display panel is flattened, the bending zone of the flexible display screen has low strength, and the flexible display screen is prone to wrinkles, which affects the display effect of the foldable display panel.

[0041] In view of the above problems, the applicant proposes a supporting device for a flexible display screen, wherein the flexible display screen includes a bending zone and a non-bending zone connected to each other, and the supporting device includes: a first supporting member, at least a portion of the first supporting member is used to support the bending zone; a second supporting member, connected to the first supporting member and movably arranged along a first direction relative to the first supporting member, at least a portion of the second supporting member is used to support the bending zone; the supporting device has a folded state and an unfolded state, and during the process of changing from the folded state to the unfolded state, the first supporting member moves in the first direction in a direction away from the second supporting member; during the process of changing from the unfolded state to the folded state, the first supporting member moves in the first direction in a direction close to the second supporting member.

[0042] The support device provided by the present application supports the flexible display screen by means of the first support member and the second support member abutting against the bending zone; the support device has a folded state and an unfolded state by means of the movably arranged first support member and the second support member; in the process of transforming from the unfolded state to the folded state, the first support member moves closer to the second support member to reduce the volume of the support device; in the process of transforming from the folded state to the unfolded state, the first support member moves in the first direction away from the second support member, thereby increasing the abutment range of the support device against the bending zone, improving the supporting strength of the support device against the bending zone, avoiding wrinkles on the flexible display screen, ensuring the display effect of the flexible display screen, and improving the service life of the flexible display screen.

[0043] The support device provided by the embodiment of the present application is introduced below in conjunction with the accompanying drawings. It is noted that the x direction in the accompanying drawings is the first direction, and the y direction in the accompanying drawings is the thickness direction of the support device. In the accompanying drawings, for the convenience of drawing, the dimensions in the drawings are not necessarily proportional to the actual dimensions.

[0044] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the front view structure of the support device and the flexible display screen in some embodiments of the present application when the support device is in a folded state; Figure 2 A schematic diagram of the front view structure of an example supporting device and a flexible display screen when the supporting device is in an unfolded state is shown.

[0045] like Figure 1 and Figure 2As shown, the present application provides a support device 10, which is used to support a flexible display screen 100. The flexible display screen 100 includes a bending area 101 and a non-bending area 102 connected to each other. The support device 10 includes a first support member 20 and a second support member 30, at least part of the first support member 20 is used to support the bending area 101. The second support member 30 is connected to the first support member 20 and is movably arranged relative to the first support member 20 along a first direction (x direction in the figure), at least part of the second support member 30 is used to support the bending area 101. The support device 10 has a folded state and an unfolded state. In the process of changing from the folded state to the unfolded state, the first support member 20 moves in a direction away from the second support member 30 in the first direction x. In the process of changing from the unfolded state to the folded state, the first support member 20 moves in a direction close to the second support member 30 in the first direction x. The first direction x is parallel to the extension direction of the flexible display screen 100.

[0046] Optionally, the support device 10 is a thin plate structure with a thickness of 70um to 200um. The material of the support device 10 can be SUS301, SUS304, SUS316L, amorphous alloy, copper-nickel-tin alloy, titanium alloy, magnesium alloy, polymer, carbon fiber, glass, etc. The support device 10 is located on the non-display surface side of the flexible display screen 100 and is attached to the flexible display screen 100 to support the flexible display screen 100. Since the non-bending area 102 of the flexible display screen 100 does not need to be bent repeatedly, the support structure can be arranged in a full-paving manner, so that the non-bending area 102 is not prone to defects such as wrinkles. The bending area 101 of the flexible display screen 100 is flexible and can be bent repeatedly, so that the flexible display screen 100 has a bending state and an unfolded state. When the flexible display screen 100 is in a bent state, the bending area 101 is U-shaped or teardrop-shaped. At this time, the bending area 101 is not prone to wrinkles under the action of the bending force. When the flexible display screen 100 is in the unfolded state, the surfaces of the bending area 101 and the non-bending area 102 are located in the same plane. At this time, the bending area 101 is prone to wrinkles due to insufficient support force. Since the bending area 101 needs to be bent repeatedly, if the support device 10 is arranged in a full-coverage manner, when the support devices 10 are switched, the support devices 10 may squeeze each other, which in turn applies force to the flexible display screen 100, causing appearance defects on the flexible display screen 100. Therefore, this embodiment uses a support device 10 with a transformable state, and the folded state of the support device 10 corresponds to the bending state of the flexible display screen 100, and the unfolded state of the support device 10 corresponds to the unfolded state of the flexible display screen 100.

[0047] The support device 10 provided in this embodiment supports the flexible display screen 100 by means of the first support member 20 and the second support member 30 abutting against the bending zone 101; the support device 10 has a folded state and an unfolded state by means of the movably arranged first support member 20 and the second support member 30; in the process of transforming from the unfolded state to the folded state, the first support member 20 moves toward the second support member 30 to reduce the volume of the support device 10; in the process of transforming from the folded state to the unfolded state, the first support member 20 moves in the first direction x in a direction away from the second support member 30, thereby increasing the abutment range of the support device 10 against the bending zone 101, improving the supporting strength of the support device 10 against the bending zone 101, improving the problem of the flexible display screen 100 being prone to wrinkles in the unfolded state, ensuring the display effect of the flexible display screen 100, and improving the service life of the flexible display screen 100.

[0048] Please refer to Figures 3 to 5 , Figure 3 A schematic diagram of a side view structure of an exemplary support device and a flexible display screen is shown; Figure 4 An example is shown Figure 3 A cross-sectional view of the support device and the flexible display screen at section AA when the support device is in a folded state; Figure 5 An example is shown Figure 3 A cross-sectional view of the support device and the flexible display screen at section AA when the support device is in an unfolded state. Figure 3 The cross-sectional view under section AA is symmetrical on both sides. Figure 4 and Figure 5 Both Figure 3 Partial view under section AA, omitted part and Figure 4 , Figure 5 symmetry.

[0049] like Figures 3 to 5 As shown, in some optional embodiments, the support device 10 may further include a driving mechanism and a transmission member 50, wherein the driving mechanism includes a rotating member 40 rotatably arranged along its own axis. The transmission member 50 is connected between the rotating member 40 and the first support member 20, so that when the rotating member 40 rotates, the first support member 20 can be driven to move along the first direction x through the transmission member 50.

[0050] The support device 10 provided in this embodiment drives the transmission member 50 to move by the rotation of the rotating member 40, thereby driving the first support member 20 to move along the first direction x, and has a simple structure and low cost.

[0051] In some optional embodiments, the driving mechanism may further include a motor (not shown), which is connected to the rotating member 40 and is used to drive the rotating member 40 to rotate, thereby driving the first supporting member 20 to move along the first direction x.

[0052] The motor is connected to the processor of the electronic device, and the processor can determine the state of the flexible display screen 100 according to the rotation angle of the hinge in the display panel, and then control the start and stop of the motor and the direction of the output torque. The motor outputs torque to the rotating member 40 to rotate the rotating member 40, driving the first support member 20 to move along the first direction x, thereby realizing the state change of the support device 10.

[0053] The support device 10 provided in this embodiment uses a motor connected to a processor as a power source. The processor automatically determines the state of the flexible display screen 100 and controls the support device 10 to change its state, so that the support device 10 does not require manual operation and the state change response is sensitive.

[0054] In some optional embodiments, the rotating member 40 is a gear. The transmission member 50 includes a first connection portion 51 and a second connection portion 52 , wherein the first connection portion 51 is connected to the first support member 20 , and the second connection portion 52 is a rack that can mesh with the rotating member 40 .

[0055] The supporting device 10 provided in this embodiment connects the rotating member 40 and the transmission member 50 by means of a gear rack, has a simple structure and high transmission stability, and is not prone to jamming.

[0056] Please refer to Figure 6 , Figure 6 Another example is shown Figure 3 A cross-sectional view of the support device and the flexible display screen at section AA when the support device is in a folded state. Figure 3 The cross-sectional view under section AA is symmetrical on both sides. Figure 6 for Figure 3 Partial view under section AA, omitted part and Figure 6 symmetry.

[0057] like Figure 6 As shown, in some optional embodiments, the transmission member 50 can be wound around the rotating member 40, so that when the rotating member 40 rotates, the transmission member 50 is rolled out from the rotating member 40 and used to drive the first support member 20 to move in the first direction x in a direction away from the second support member 30. Alternatively, the transmission member 50 is wound around the rotating member 40 and used to drive the first support member 20 to move in the first direction x in a direction close to the second support member 30.

[0058] The second connecting portion 52 of the transmission member 50 is connected to the rotating member 40, and the second connecting portion 2 is flexible and can be repeatedly curled.

[0059] The supporting device 10 provided in this embodiment connects the rotating member 40 and the transmission member 50 in a manner similar to a tape measure, and has a simple structure and is easy to implement.

[0060] In some optional embodiments, the supporting device 10 may further include an elastic member 60, and the transmission member 50 is connected to the first supporting member 20 via the elastic member 60. The elastic member 60 may be a spring.

[0061] The support device 10 provided in this embodiment connects the transmission member 50 and the first support member 20 through the elastic member 60. The elastic member 60 can delay the driving force transmitted by the transmission member 50 to the first support member 20, and can convert mechanical energy into its own elastic potential energy, so that when the transmission member 50 drives the first support member 20 to move, the risk of the first support member 20 squeezing the flexible display screen 100 and causing wrinkles on the flexible display screen 100 is reduced when the force is too large.

[0062] Please refer to Figures 6 to 8 , Figure 7 An example is shown Figure 4 A cross-sectional view of the support device and the flexible display screen at the BB section; Figure 8 An example is shown Figure 3 A cross-sectional view of the support device in section AA when it is in the unfolded state. Figure 3 The cross-sectional view under section AA is symmetrical on both sides. Figure 8 for Figure 3 Partial view under section AA, omitted part and Figure 8 symmetry.

One of the first slide groove 71 and the first slider 72 is disposed on the first support member 20, and the other is disposed on the second support member 30. The first slide groove 71 is formed to extend along the first direction x, and the first slider 72 is limited to the first slide groove 71 and is movably disposed along the first slide groove 71.

[0066] The support device 10 provided in this embodiment connects the first support member 20 and the second support member 30 through the first slide groove 71 and the first slider 72 limited in the first slide groove 71. The first slide groove 71 is extended and formed along the first direction x, so that the first support member 20 moves along the first direction x.

[0067] In some optional embodiments, the first slide groove 71 is disposed on the second support member 30, the first slide groove 71 is connected to the first through hole 31, the first slider 72 is disposed on the first support member 20, and at least part of the first connection hole 21 is located on the first slider 72. Alternatively, the first slider 72 is disposed on the second support member 30, and the first through hole passes through the first slider 72.

[0068] In some optional embodiments, the first slide slot 71 includes a first bottom portion 711 and two first side portions 712 disposed on both sides of the first bottom portion 711. The first slider 72 includes two second side portions 721 facing the two first side portions 712 respectively, and the second side portions 721 are movably disposed relative to the first side portion 712 along the first direction x.

[0070] The support device 10 provided in this embodiment effectively reduces the thickness of the first support member 20 and the second support member 30 by abutting the second bottom portion 722 against the bending area 101 , thereby reducing the volume of the support device 10 .

[0071] In some optional embodiments, a second slide groove 73 extending along the first direction x is disposed on one of the first side portion 712 and the second side portion 721 , and a second slider 74 movably disposed along the second slide groove 73 is disposed on the other side.

Each stop portion 733 is connected to each third side portion 732, and the two stop portions 733 extend in a direction close to each other and are spaced apart from each other to form an opening (not shown). The second slider 74 includes a limiting portion 741 and a connecting portion 742, the limiting portion 741 is located between the two third side portions 732 and stops at the stop portion 733, and the connecting portion 742 is connected to the limiting portion 741 and extends from the opening to connect to the first slider 72.

[0073] The support device 10 provided in this embodiment limits the movement of the limiting portion 741 to the two sides of the second slide groove 73 through the third side portion 732. Through the interaction between the limiting portion 741 and the stop portion 733, the second slider 74 and the second slide groove 73 can only slide against each other without separating, thereby allowing the first support member 20 and the second support member 30 to slide against each other without separating.
