[0043] In order to make the objectives, technical solutions and advantages of this application more clear, this application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0044] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should have the usual meanings understood by people with ordinary skills in the field to which this application belongs. The "first", "second" and similar words used in the embodiments of the present application do not indicate any order, quantity or importance, but are only used to distinguish different components.

"Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0045] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0046] In the related technology, the mainstream roll-up solution of the scroll display device is to use a cross-coordinated comb structure, which drives the flexible screen to expand or retract through the relative movement of the comb structure. Figure 1 As shown; when the two mutually cooperating comb tooth structures move away from each other and gradually extend the overall structure, the comb tooth structure drives the flexible panel connected to it to slide, and the flexible panel is unfolded under the traction force of the comb tooth structure. Conversely, when the two comb tooth structures approach each other and gradually shorten the overall structure, the flexible panel will be driven to slide in the opposite direction, thereby retracting the flexible panel to its original position; however, since the cross-cooperating comb tooth structures not only play a traction role on the flexible panel, but also need to support the surface of the flexible panel, when the flexible panel is unfolded, its sliding distance usually does not exceed the height of one of the comb tooth structures, that is, it does not exceed the height of the original display panel. Therefore, when the flexible screen is unfolded, it is limited by the matching position of the comb tooth structure, and the sliding distance of the flexible screen is relatively short, and the display area of ​​the flexible panel changes less, affecting the user's experience of the flexible screen; in addition, since the flexible panel is relatively soft as a whole, when the flexible panel is retracted, the comb tooth structures close to each other are likely to produce opposite directions of force on the flexible panel, causing the surface of the flexible panel to bulge or wrinkle, affecting the flatness of the flexible display module.

[0047] In view of this, the present application discloses a flexible display module, including a sliding shaft 1, a flexible panel 2, a linkage structure 3 and two groups of guide structures 4; the side of the flexible panel 2 facing away from the light emitting direction is against the sliding shaft 1; the linkage structure 3 and the two groups of guide structures 4 are both arranged on the sliding shaft 1, and the two groups of guide structures 4 are respectively located on both sides of the sliding shaft 1; the guide structure 4 is connected to the flexible panel 2 and is configured to output a driving action to drive the flexible panel 2 to slide around the sliding shaft 1; the linkage structure 3 is respectively connected to the two groups of guide structures 4 for transmission, and is configured to make the two groups of guide structures 4 output a driving action corresponding to the sliding direction of the flexible panel 2.

[0048] like Figures 2A-6 As shown, the present application provides a flexible display module, which includes a scroll 1 and a flexible panel 2; wherein the flexible panel 2 has a light-emitting side and a backlight side arranged opposite to each other, the light-emitting side serves as the display area of ​​the flexible panel 2, and the backlight side abuts against the side of the scroll 1, so that the scroll 1 divides the backlight side of the flexible panel 2 into two sliding areas; in addition, the flexible display module also includes a linkage structure 3 and two sets of guide structures 4 arranged on the scroll 1, the linkage structure 3 is connected to the two sets of guide structures 4 in a transmission manner, and the linkage structure 3 can synchronously drive the two sets of guide structures 4 to output a direction that is consistent with the sliding direction of the flexible panel 2 Corresponding driving action; since the two groups of guide structures 4 are respectively connected to the two sliding areas of the flexible panel 2, when one group of guide structures 4 is driven to drive the flexible panel 2 to slide in the direction away from the sliding scroll 1, the other guide structure 4 drives the flexible panel 2 to slide in the direction close to the sliding scroll 1, so that the area of ​​the sliding area on one side of the sliding scroll 1 gradually increases, and the area of ​​the sliding area on the other side of the sliding scroll 1 gradually decreases, thereby realizing the expansion or retraction of the flexible panel 2, and can greatly extend the sliding distance of the flexible panel 2 on the sliding scroll 1, change its display area, and improve the user experience of the flexible display module.

[0049] In addition, the two guide structures 4 of the flexible display module in the present application move synchronously driven by the linkage structure 3, so that the two sets of guide structures 4 output driving actions that are adapted to the sliding direction of the flexible panel 2, thereby making the area changes of the sliding areas on both sides of the sliding shaft 1 the same, ensuring that the flexible panel 2 will not be subjected to forces in opposite directions during the sliding process, preventing the flexible panel 2 from bulging or wrinkling, and ensuring that the flexible panel 2 always has good flatness.

[0050] For example, the initial state of the flexible display module is as follows: Figure 2A and 2BAs shown, the flexible panel 2 is in a retracted state. At this time, the guide structure 4 in the vertical direction is in a folded state, and the guide structure 4 in the horizontal direction is in an unfolded state to ensure the flatness of the display panel as a whole. When the display area of ​​the display panel needs to be adjusted, the linkage structure 3 is used to drive the guide structures 4 in the vertical and horizontal directions to move synchronously, that is, the linkage structure 3 drives the guide structure 4 in the vertical direction to output a driving action to gradually unfold the guide structure 4 and drive the flexible panel 2 to slide in the vertical direction, so that the sliding area on this side extends in the direction away from the scroll axis 1. At the same time, the linkage structure 3 drives the guide structure 4 in the horizontal direction to synchronously output a driving action, so that the guide structure 4 gradually folds and drives the other sliding area of ​​the flexible panel 2 to slide in the horizontal direction, and drives the flexible panel 2 to shrink in the direction close to the scroll axis 1. At this time, the display area of ​​the flexible panel 2 in the vertical direction becomes larger and larger, while the display area of ​​the flexible panel 2 in the horizontal direction becomes smaller and smaller, until the two guide structures 4 drive the flexible panel 2 to be fully unfolded in the vertical direction, as shown in FIG. Figure 3A and Figure 3B shown.

[0051] In some embodiments, the guide structure 4 includes a first transmission component 410, a first support rod 420 and a second support rod 430; the first transmission component 410 is respectively connected to one end of the first support rod 420 and one end of the second support rod 430; the other end of the first support rod 420 is rotatably connected to the side of the flexible panel 2 away from its light emitting direction; the other end of the second support rod 430 is transmission-connected to the linkage structure 3.

[0052] like Figure 2B and Figure 3B As shown, in the flexible display module, the linkage structure 3 is used to drive the two groups of guide structures 4 connected thereto to move, so that the two groups of guide structures 4 output corresponding driving actions, driving the flexible panel 2 to slide adaptively on the side of the sliding scroll 1; wherein, any guide structure 4 includes a first transmission component 410, a first support rod 420 and a second support rod 430, the two ends of the first support rod 420 are respectively connected to the first transmission component 410 and the flexible panel 2, and the second support rod 430 is respectively connected to the first transmission component 410 and the linkage component. In this embodiment, the linkage component can drive the second support rod 430 to move, so that the first support rod 420 swings along the connection point between it and the sliding scroll 1, and the second support rod 430 drives the first support rod 420 to move through the first transmission component 410, thereby making the connection point between the first support rod 420 and the flexible panel 2, and the connection point between the second support rod 430 and the linkage structure 3 move away from or close to each other, driving the flexible panel 2 to slide and roll along the side of the sliding scroll 1 to adjust the unrolling state of the flexible panel 2.

[0053] In addition, in this embodiment, when the linkage structure 3 drives the two groups of guide structures 4 to output the driving action, in order to ensure that the flexible panel 2 always remains flat and does not bulge or wrinkle, for the two groups of guide structures 4 that drive the movement of the two sliding areas of the flexible panel 2, one group moves in the direction close to the sliding shaft 1, that is, the guide structure 4 on this side is folded. At this time, the connection point between the first support rod 420 of the guide structure 4 and the flexible panel 2 and the connection point between the second support rod 430 and the linkage structure 3 gradually approach each other, thereby driving the area of ​​the sliding area to gradually decrease; and the other group moves in the direction away from the sliding shaft 1, that is, the guide structure 4 on this side is unfolded. At this time, the connection point between the first support rod 420 of the guide structure 4 and the flexible panel 2 and the connection between the second support rod 430 and the linkage structure 3 gradually move away from each other, thereby driving the area of ​​the sliding area to gradually increase, thereby realizing the adjustment of the display area of ​​the flexible panel 2.

[0054] It should be noted that if Figure 2B and 3B As shown, when the guide structure 4 drives the flexible panel 2 on one side to be in the unfolded state, the extension line of the first support rod 420 in the side guide structure 4 coincides with the extension line of the second support rod 430, and at this time the area of ​​the flexible panel 2 on this side is the largest; when the guide structure 4 drives the flexible panel 2 on one side to be in the folded state, the extension line of the first support rod 420 in the side guide structure 4 coincides with the extension line of the second support rod 430 and does not coincide, and at this time the area of ​​the flexible panel 2 on this side is the smallest.

[0055] In some embodiments, the first transmission component 410 includes a first gear 411 and a second gear 412; the first gear 411 is fixedly connected to one end of the first support rod 420, the second gear 412 is fixedly connected to one end of the second support rod 430, and the second gear 412 is meshed with the first gear 411.

[0056] like Figure 2B and Figure 3BAs shown, when the linkage structure 3 drives the guide structure 4 to output the driving action, it will drive the second support rod 430 connected to it to move, and then drive the first support rod 420 to move through the first transmission component 410, so that the first support rod 420 drives the flexible panel 2 to slide on the side of the sliding scroll 1; wherein, the first transmission component 410 may include a first gear 411 and a second gear 412. When the second support rod 430 moves, it drives the second gear 412 fixedly connected to it to move synchronously. Since the second gear 412 is meshed with the first gear 411, the first support rod 420 is fixedly connected to the first gear 411. Therefore, the second gear 412 that moves synchronously with the second support rod 430 can drive the first gear 411 to move through the second gear teeth, so as to drive the first support rod 420 to move through the first gear 411, thereby realizing the expansion and folding of the guide structure 4, thereby driving the flexible panel 2 to expand or shrink.

[0057] In some embodiments, the first transmission component 410 further includes an anti-slip connecting rod 413 ; both ends of the anti-slip connecting rod 413 are rotatably connected to the first gear 411 and the second gear 412 , respectively.

[0058] like Figure 2B and Figure 3B As shown, in this embodiment, the first transmission component 410 is connected to the first support rod 420 and the second support rod 430 respectively. When the linkage structure 3 drives the second support rod 430 to move, the second support rod 430 can drive the first support rod 420 through the first transmission component 410, thereby using the first support rod 420 to drive the flexible panel 2 to move; wherein, the first transmission component 410 includes an anti-slip connecting rod 413 that is also rotatably connected to the first gear 411 and the second gear 412 respectively, so that the first gear 411 and the second gear 412 are always engaged, avoiding the problem of the first gear 411 and the second gear 412 being disengaged when the second support rod 430 drives the first support rod 420 to move through the first gear 411 and the second gear 412, thereby improving the stability of the output driving action of the guide structure 4.

[0059] In some embodiments, a connecting portion 5 is further included; the connecting portion 5 is fixedly connected to one side of the flexible panel 2 away from its light emitting direction, and is rotatably connected to the other end of the first support rod 420; Figure 2B and Figure 3BAs shown, by providing a connecting portion 5 on the side of the flexible panel 2 away from its light emitting direction, and making the connecting portion 5 rotatably connected to the first support rod 420 in the guide structure 4, the guiding structure 4 can drive the flexible panel 2 to slide on the side of the sliding scroll 1 through the connecting portion 5; wherein, in this embodiment, the connecting portion 5 and the flexible panel 2 can be connected by gluing with an elastomeric pressure-sensitive adhesive, a resin-type pressure-sensitive adhesive or an acrylic pressure-sensitive adhesive, thereby reducing the difficulty of connecting the connecting portion 5 and the flexible panel 2 and ensuring good firmness between the two.

[0060] In addition, if Figure 2B and Figure 3B As shown, the connecting parts 5 can be arranged in two relative groups, and the two groups of connecting parts 5 can be respectively connected to the two sliding areas of the flexible panel 2, and in any sliding area, the connecting parts 5 can be fixedly connected to the edge area of ​​the flexible panel 2 away from the sliding shaft 1, so that the flexible panel 2 has a larger sliding distance.

[0061] As an alternative embodiment, the guide structure 4 can also adopt a linear drive device, and the linkage structure 3 can adopt a motion controller, and the motion controller can be used to control the linear drive device to output a corresponding drive action, which can also change the display area of ​​the flexible panel 2 on both sides of the sliding scroll 1; for example, two groups of guide structures 4 can adopt linear motors 310, and the motion controller can be used to control the movement state of the linear motors 310. When the output shaft of one group of linear motors 310 is extended in the direction away from the sliding scroll 1, the output shaft of the other group of linear motors 310 is synchronously shortened, thereby driving the flexible panel 2 to change the roll along the surface of the sliding scroll 1, and the area of ​​the flexible panel 2 on one side of the sliding scroll 1 is increased, and the area on the other side is gradually reduced, thereby realizing the adjustment of the display area of ​​the flexible panel 2.

[0062] In some embodiments, the linkage structure 3 includes a motor 310 and a second transmission component 320 ; the motor 310 is fixedly connected to the sliding reel 1 , the second transmission component 320 is connected to the output shaft of the motor 310 , and the second transmission component 320 is transmission-connected to the two sets of guide structures 4 .

[0063] like Figure 2B 、 3B and Figure 4As shown, the linkage structure 3 is respectively connected to the two groups of guide structures 4 in a transmission manner, so that it can drive the two groups of guide structures 4 to output actions that are adapted to the sliding direction of the flexible panel 2, so as to drive the display panel to slide and roll on the side of the scroll shaft 1, thereby adjusting its display area; wherein, the linkage structure 3 includes a motor 310 and a second transmission component 320, and the motor 310 is used to provide driving force and drive the second transmission component 320 to move, and the two groups of guide structures 4 are respectively driven to move by the second transmission component 320, so that the guide structure 4 outputs a corresponding driving action to drive the flexible panel 2 to slide and roll; it should be noted that the specific model, specification and size of the motor 310 used in this embodiment can be selected according to the actual needs of the flexible display module, and will not be repeated here.

[0064] In some embodiments, the second transmission component 320 includes a first worm gear 321, a second worm gear 322, a first worm 323 and a second worm 324; the first worm gear 321 and the second worm gear 322 are both rotatably connected to the sliding reel 1, and the first worm gear 321 and the second worm gear 322 are respectively fixedly connected to the two sets of guide structures 4; the first worm 323 and the second worm 324 are coaxially arranged, the first worm 323 is fixedly connected to the output shaft of the motor 310, and meshes with the first worm gear 321; the second worm 324 meshes with the second worm gear 322; the worm teeth of the first worm 323 and the worm teeth of the second worm 324 are arranged in the opposite direction.

[0065] like Figure 2B 、 3B and Figure 4As shown, in this embodiment, in addition to providing power for the two sets of guide structures 4, the linkage structure 3 also needs to drive the two sets of guide structures 4 to output corresponding driving actions to make the flexible panel 2 stably slide on the scroll shaft 1; wherein, the second transmission component 320 includes a first worm gear 321, a second worm gear 322, a first worm 323 and a second worm 324. When the motor 310 in the flexible display module is controlled to operate, the first worm 323 and the second worm 324 connected to its output shaft are driven to rotate synchronously. Since the first worm gear 321 and the second worm gear 322 are both rotatably set on the scroll shaft 1, and the two are respectively connected to the first worm 323 and the second worm 324 for transmission, and are respectively It is connected to two sets of guide structures 4, so the rotating first worm 323 and the second worm 324 can drive the first worm wheel 321 and the second worm wheel 322 to rotate synchronously through the worm gear teeth, and since the worm gear teeth of the first worm 323 and the worm gear teeth of the second worm 324 are set in opposite directions, and the two rotate in the same direction under the drive of the motor 310, the motor 310 can drive one set of guide structures 4 through the second transmission component 320 to drive the flexible panel 2 to extend in the direction away from the sliding scroll 1, and the other set of guide structures 4 drives the flexible panel 2 to shrink in the direction close to the sliding scroll 1, thereby adjusting the display area of ​​the display panel to ensure that the display panel is always in a flat state.

[0066] In some embodiments, the flexible display module further includes a tensioning rope 6 ; both ends of the tensioning rope 6 are fixedly connected to the side of the flexible panel 2 away from the light emitting direction thereof, and are wound around the side of the sliding reel 1 .

[0067] like Figure 2B and Figure 3B As shown, the flexible display module of this embodiment also includes a tensioning rope 6 for supporting the backlight side of the flexible panel 2, so as to maintain the flatness of the flexible panel 2 during the sliding and rolling process; wherein, in order to ensure the tensioning effect and supporting capacity of the tensioning rope 6 on the flexible panel 2, the two ends of the tensioning rope 6 are respectively fixedly connected to the sliding and rolling areas on both sides of the sliding and rolling shaft 1, and are in a tensioned state, so as to flatten the bulging area generated by the flexible panel 2, so as to avoid bulging or warping of the flexible panel 2.

[0068] In some embodiments, the flexible display module also includes a first guide wheel 7; the connecting part 5 is provided with a first accommodating cavity 5a, the first guide wheel 7 is located in the first limiting hole and is rotatably connected to the connecting part 5, and the tensioning rope 6 is wrapped around the arc surface of the first guide wheel 7.

[0069] In this embodiment, the flexible display module further includes a first guide wheel 7, such as Figure 2B 、 Figure 3B and Figure 5As shown, in order to ensure that the flexible panel 2 has a larger sliding distance, the connecting part 5 is fixedly connected to the edge area of ​​the flexible panel 2 away from the sliding shaft 1. By opening a first accommodating cavity 5a on the connecting part 5 and setting the first guide wheel 7 in the first limiting hole, when the tensioning rope 6 is wound around the arc surface of the first guide wheel 7, the extension direction of the tensioning rope 6 can be changed, which facilitates the connection of the tensioning rope 6 to the back of the display panel, ensuring the firmness of the connection between the tensioning rope 6 and the flexible panel 2, and improving the flattening effect of the flexible panel 2.

[0070] In some embodiments, the flexible display module also includes a tensioning component 8, which includes a bracket 810, a second guide wheel 820, a connecting pin 830 and a tensioning spring 840; a second accommodating cavity 810a is opened on the bracket 810, the second guide wheel 820 is located in the second accommodating cavity 810a and is rotatably connected to the bracket 810, and the tensioning rope 6 is wrapped around the arc surface of the second guide wheel 820; the connecting pin 830 is slidingly connected to the bracket 810, and the end of the connecting pin 830 is connected to the guide structure 4; the tensioning spring 840 is sleeved on the connecting pin 830, and the two ends of the tensioning spring 840 are respectively abutted against the guide structure 4 and the bracket 810.

[0071] like Figure 2B 、 Figure 3B and Figure 6 As shown, in order to ensure that the tensioning rope 6 has a good flattening effect, it is necessary to make the tensioning rope 6 have sufficient tensioning force to avoid the flexible panel 2 from bulging or warping during the sliding and rolling process; in this embodiment, by arranging a tensioning component 8 on the connecting portion 5, sufficient tensioning force can be provided for the tensioning rope 6 to tighten the tensioning rope 6; wherein, the tensioning component 8 includes a bracket 810, a second guide wheel 820, a connecting pin 830 and a tensioning spring 840, the second guide wheel 820 is located in the second accommodating cavity 810a, and the tensioning rope 6 The connecting pin 830 is arranged along the arc surface of the second guide wheel 820, and is slidingly connected to the bracket 810. The end of the connecting pin 830 is connected to the guide structure 4. The tensioning spring 840 is sleeved on the connecting pin 830 and abuts against the guide structure 4 and the bracket 810 respectively. By arranging the elastic tensioning spring 840 between the connecting part 5 and the bracket 810, the elastic force of the tensioning spring 840 is used to apply a thrust to the bracket 810, so that the tensioning rope 6 is in a tensioned state, thereby ensuring the tensioning rope 6 has a flattening effect on the flexible panel 2.

[0072] In some embodiments, the flexible display module further includes a guide column 9 ; the end of the guide column 9 is connected to the sliding reel 1 , the tensioning rope 6 is wound around the curved surface of the guide column 9 , and the extension line of the guide column 9 is parallel to the flexible panel 2 .

[0073] In this embodiment, since the side of the flexible panel 2 away from the light emitting direction thereof abuts against the side of the sliding reel 1, and the tensioning rope 6 is arranged on the back of the flexible panel 2; therefore, Figure 2B and Figure 3B As shown, a giveway groove can be provided on the sliding reel 1 so that the tensioning rope 6 can pass through the inside of the giveway groove, thereby preventing the tensioning rope 6 from replicating the morphology of the tensioning rope 6 on the surface of the flexible panel 2 after being bonded to the sliding reel 1 and the flexible panel 2, thereby avoiding leaving indentations on the surface of the line panel; by providing a guide column 9 in the giveway groove and fixing the guide column 9 to the side wall of the giveway groove, that is, fixing the guide column 9 to the sliding reel 1, the extension direction of the tensioning rope 6 can be changed so that the tensioning rope 6 can slide synchronously with the sliding of the flexible panel 2.

[0074] In some embodiments, the flexible display module further includes a limiting post 10 ; the limiting post 10 is connected to the guide post 9 , and the arc-shaped surface of the limiting post 10 abuts against the side of the flexible panel 2 away from the light emitting direction thereof.

[0075] like Figure 2B and Figure 3B As shown, the guide column 9 mentioned above can change the extension direction of the tensioning rope 6 so that it slides synchronously with the flexible panel 2 to flatten the flexible panel 2; wherein, by arranging a limit column 10 at the end of the guide shaft, a limit gap is formed between the limit column 10 and the side wall of the clearance groove, thereby avoiding the tensioning rope 6 from moving significantly on the surface of the guide column 9, preventing the tensioning rope 6 from deviating from its sliding direction, and ensuring that the sliding direction of the flexible panel 2 has good linearity; in addition, since the sliding reel 1 is provided with a clearance groove, the limit column 10 is provided at the end of the guide shaft, which can support the flexible panel 2 in the clearance groove area, avoiding the problem of the flexible panel 2 resting on the clearance groove area being concave, and ensuring that the flexible panel 2 has good flatness.

[0076] In some embodiments, the flexible display module also includes a fixed block 11 and a limiting portion 12; the fixed block 11 is fixedly connected to the side of the flexible panel 2 that is away from its light-emitting direction, and is fixedly connected to the end of the tensioning rope 6; the limiting portion 12 is arranged on the sliding scroll 1, and the structure of the limiting portion 12 is adapted to the structure of the fixed block 11, and is configured to limit the lateral sliding of the fixed block 11.

[0077] like Figure 2B and 3B As shown, in this embodiment, the flexible display module further includes a fixed block 11 and a limiting portion 12, wherein the fixed block 11 can be fixedly connected to the side of the flexible panel 2 away from its light emitting direction, and is fixedly connected to the end of the tensioning rope 6 to provide an installation position for the tensioning rope 6 and reduce the difficulty of connecting the tensioning rope 6; a limiting portion 12 is also provided on the sliding reel 1, and the structure of the limiting portion 12 is adapted to the structure of the fixed block 11 to limit the lateral sliding of the fixed block 11. For example, Figure 2BAs shown, when the guide structure 4 drives the flexible panel 2 located on one side of the sliding shaft 1 to retract, the fixed block 11 will move in the direction close to the sliding shaft 1 and gradually enter the limiting portion 12 provided on the sliding shaft 1. The limiting portion 12 is used to limit the fixed block 11 to prevent the flexible panel 2 in this state from sliding sideways to a large extent, thereby ensuring that the flexible module has better stability.
