FIELD OF INVENTION
The present application relates to the field of display, and in particular, to a flexible display module and an electronic device.
DESCRIPTION OF PRIOR ART
With the development of flexible screens, from folding screens to sliding screens, it is all to achieve a larger screen display ratio for smaller personal terminals. In smaller personal terminals, it is obvious that a screen-to-casing ratio of the sliding screen is higher than that of the folding screen, and personal terminal is more compact.
The sliding screen includes an expanded state and a contracted state. In the expanded state, part of the flexible display panel stored in a casing is drawn out after passing through a roller to increase the display area; and in the contracted state, an exposed part of the flexible display panel is then stored back into the casing through the roller to reduce the display area and facilitate user portability. The flexible display panel includes a plurality of bendable flexible layers so as to facilitate the winding of the flexible display panel. When the sliding screen is in an expanded or contracted state for a long time, portions of the flexible display panel corresponding to the roller and other winding parts are prone to curl marks. In order to eliminate the curl marks faster, in the process of assembling the flexible display panel and the terminal, an initial tensile force will be applied to the flexible display panel to tension the flexible display panel, and during the process that the sliding screen switches between the expanded state and the contracted state, the curl marks of the flexible display panel can be eliminated.
During research and practice of the prior art, the inventors of the present application found that the initial tension applied to the flexible display panel easily leads to a deformation of the roller, and especially a deformation of a suspended part in a middle of the roller is particularly serious, which can cause the roller to not rotate smoothly, resulting in jamming, which in turn leads to increased sliding load.

In addition, it should be understood that the specific implementations described here are only used to illustrate and explain the application, and are not used to limit the application. In the present application, unless otherwise stated, the orientation words used such as “upper” and “lower” generally refer to the upper and lower directions of the device in actual use or working state, and specifically refer to the drawing directions in the drawings, while “inner” and “outer” refer to the outline of the device.
Embodiments of the present application provide a flexible display module and an electronic device. Each of them will be described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.
Referring to FIGS. 1 and 2, an embodiment of the present application provides a flexible display module 10, which includes a fixing bracket 100, a middle frame bracket 200, a rolling unit 300 and a flexible display panel 400, and the middle frame bracket 200 is slidably connected to the fixing bracket 100. Specifically, the middle frame bracket 200 is slidably connected to the fixing bracket 100 along a first direction X, that is, the middle frame bracket 200 can slide along the first direction X on the fixing bracket 100.
Specifically, the rolling unit 300 is disposed on the fixing bracket 100, and the rolling unit 300 is configured to support the flexible display panel 400. The rolling unit 300 includes at least two rolling elements 310, axial directions of the at least two rolling elements 310 are parallel to each other, and the at least two rolling elements 310 are arranged in sequence along the axial directions, that is, at least two rolling elements 310 are arranged in a row. The rolling elements 310 can be, but is not limited to, a platen or a roller. Each of the rolling elements 310 is rotatably connected to the fixing bracket 100, that is, the rolling elements 310 can rotate on the fixing bracket 100. In this embodiment, at least two rolling elements 310 are arranged at intervals along the first direction X, a rotation axis 320 of each of the rolling elements 310 relative to the rotation of the fixing bracket 100 extends along a second direction Y, and the axial direction of the rolling elements 310 is parallel to the second direction Y, the first direction X is vertical to the second direction Y. Of course, according to actual situations and specific requirements, an included angle between the first direction X and the second direction Y can be adjusted appropriately. It should be noted that the above-mentioned axial direction refers to a direction along a central axis of each of the rolling elements 310.
Optionally, at least two rolling elements 310 may be coaxially arranged. It should be noted that the condition that the at least two rolling elements 310 can be coaxially arranged means that the rotation axes of the at least two rolling elements 310 that rotate relative to the fixing bracket 100 are collinear.
Specifically, a first end 421 of the flexible display panel 400 is fixedly connected to the middle frame bracket 200, and the flexible display panel 400 is partially supported on the rolling elements 310. In such a structure, when the middle frame bracket 200 slides on the fixing bracket 100, the flexible display panel 400 will also move with the middle frame bracket 200, and during the movement of the flexible display panel 400, the rolling elements 310 will also rotate, so that a back of the flexible display panel 400 is stably supported on the middle frame bracket 200 and the at least two rolling elements 310.
Specifically, both ends of each of the rolling elements 310 are supported on the fixing bracket 100, and each of the rolling elements 310 can be stably fixed on the fixing bracket 100, which can improve the reliability of the rolling elements 310.
As shown in FIG. 4, if the rolling unit 300 of the embodiment of the present application is set as a roller 350, when the middle frame bracket 200 slides on the fixing bracket 100, the flexible display panel 400 will also move with the middle frame bracket 200, and during the movement of the flexible display panel 400, the roller 350 also rotates, so that a back of the flexible display panel 400 is supported on the middle frame bracket 200 and the roller 350. Because a length of the roller 350 is relatively long, a middle of the roller 350 is suspended without any support, so the middle of the roller 350 is easily collapsed and deformed, resulting in a jam phenomenon during a rotation of the roller 350, and a sliding load of the middle frame bracket 200 is added.
In order to solve the above problems, as shown in FIG. 4, the present application adopts multi-segment rolling elements 310 to replace the rollers 350 to support the flexible display panel 400. Since a length of the rolling elements 310 is less than a length of the roller 350, and the two ends of each segment of the rolling elements 310 are supported on the fixing bracket 100, the above-mentioned rolling elements 310 are evenly stressed, the supporting strength is higher, and the rolling elements 310 is not easily deformed. As such, there is no jamming when the rolling elements 310 rotates, effectively reducing the sliding load of the middle frame bracket 200 relative to the fixing bracket 100.
Specifically, as shown in FIGS. 1 and 2, the flexible display module 10 further includes a winding mechanism 500, a second end 422 of the flexible display panel 400 is connected to the winding mechanism 500, and the winding mechanism 500 is configured to wind the flexible display panel 400. As shown in FIG. 5, when the middle frame bracket 200 moves to the left, the winding mechanism 500 releases the flexible display panel 400, and the middle frame bracket 200 drives the flexible display panel 400 to move to the left. At the same time, the rolling elements 310 rotate counterclockwise, so that the flexible display panel 400 can be smoothly unfolded. When the display screen needs to be reduced, the middle frame bracket 200 can be moved to the right, the winding mechanism 500 can rewind the flexible display panel 400, and the middle frame bracket 200 drives the flexible display panel 400 to move to the right. At the same time, the rolling elements 310 rotate clockwise, so that the flexible display panel 400 can be rolled up smoothly.
Specifically, as shown in FIG. 3, the winding mechanism 500 may include a casing 510, a roller 520 and a winding mechanism 530, the casing 510 is provided with an opening 511 for the flexible display panel 400 to pass through, and the winding mechanism 530 is provided in the casing 510, the winding mechanism 530 is configured to wind the flexible display panel 400, the roller 520 is rotatably connected to an interior of the casing 510, and the second end 422 of the flexible display panel 400 enters the interior of the casing 510 from the opening 511, and passes through the roller 520 to fixedly connect to the winding mechanism 530, so that the winding mechanism 500 can wind the flexible display panel 400. In this embodiment, the winding mechanism 530 may specifically be a coil spring or a motor.
In the flexible display module 10 of the embodiment of the present application, the rolling unit 300 includes three rolling elements 310. Of course, a number of the rolling elements 310 can be adjusted according to the actual selections and specific requirements, which is not particularly limited herein.
Specifically, as shown in FIG. 2, the rolling unit 300 further includes a plurality of rotating shafts 320 and a plurality of supporting rotating elements 330, and the axial direction of the rotating shafts 320 and the axial direction of the supporting rotating elements 330 are parallel to the axial direction of the rolling elements 310; the plurality of rotating shafts 320 are arranged in sequence along the axial direction of the rotating shafts 320, the rotating shafts 320 are fixed to the rolling elements 310; the plurality of supporting rotating elements 330 are sequentially arranged along the axial direction of the supporting rotating elements 320, each of the supporting rotating elements 320 is sleeved outside one of the rotating shafts 320, each of the supporting rotating elements 320 is disposed on the fixing bracket 100, and the rotating shafts 320 are rotatably connected to the fixing bracket 100 through the supporting rotating elements 330.
Specifically, the supporting rotating elements 330 can be a bearing. Of course, the supporting rotating elements 330 can also be other elements according to the selections and specific requirements of the actual situations. For example, the supporting rotating elements 330 can be a shaft sleeve, and the shaft sleeve is sleeved on the rotating shafts 320. In addition, a relative rotation between the shaft sleeve and the rotating shafts 320 can be achieved by lubricating oil, which is not particularly limited herein.
Specifically, as shown in FIG. 2, FIG. 6, and FIG. 7, the fixing bracket 100 is provided with a mounting seat 150, the mounting seat 150 is provided with a mounting hole 151, and the supporting rotating elements 330 are mounted in the mounting hole 151. In this structure, the mounting seat 150 is protruded from one end of the fixing bracket 100 along the first direction X, opposite ends of each of the rolling elements 310 are respectively provided with the mounting seat 150, and the two ends of each of the rolling elements 310 are respectively rotatably connected to the mounting seat 150 by corresponding ones of the rotating shafts 320 and the supporting rotating elements 330, so that the rolling elements 310 are suspended in the air, so as to realize the rotation of the rolling elements 310 relative to the fixing bracket 100.
Specifically, as shown in FIGS. 2, 6 and 7, the mounting seat 150 is further provided with a notch 152, and the notch 152 communicates with the mounting hole 151. In such a structure, during an assembling process, the rotating shafts 320 can be fixed on the rolling elements 310, the supporting rotating elements 330 can be sleeved on the rotating shafts 320, and then the supporting rotating elements 330 at both ends of the rolling elements 310 can be installed to the mounting holes 151 through the notches 152. When the rolling unit 300 needs to be repaired or replaced, each of the supporting rotating elements 330 at both ends of each of the rolling elements 310 can be pulled out through the notches 152, so that each of the supporting rotating elements 330 at both ends of each of the rolling elements 310 are separated from the mounting holes 151, which greatly improves disassembly efficiency of the rolling elements 300.
Specifically, a width of the notch 152 is smaller than a diameter of the mounting hole 151, the diameter of the mounting hole 151 matches an outer diameter of each of the supporting rotating elements 330, that is, the diameter of the mounting hole 151 is equal to the outer diameter of each of the supporting rotating elements 330, and the width of the notch 152 is less than the outer diameter of each of the supporting rotating elements 330. In such a structure, after each of the supporting rotating elements 330 is installed into the mounting hole 151, since the width of the notch 152 is smaller than the outer diameter of each of the supporting rotating elements 330, the mounting hole 151 can stably clamp the supporting rotating element 330, and the supporting rotating element 330 is not easy to disengage from the mounting hole 151. An external force is required to make the supporting rotating elements 330 open the notches 152, so that the supporting rotating element 330 can be taken out from the mounting hole 151.
Specifically, the width of the notch 152 is less than half of the diameter of the mounting hole 151, which can ensure that the supporting rotating elements 330 are stably clamped in the mounting hole 151.

Of course, other methods may be used to make the at least two rolling elements 310 rotate separately and independently according to the actual situations and specific requirements, which is not particularly limited herein.
Specifically, as shown in FIG. 10 and FIG. 11, the rotating shafts 320 includes a first segment 321 and a second segment 322, the first segment 321 is connected with the second segment 322, the first segment 321 is configured to connect and support the rotating element 330, and the first segment 321 is configured to connect and support the rotating element 330. The second segment 322 is configured to fixedly connect the rolling element 310. Specifically, the supporting rotating element 330 is sleeved outside the first segment 321, so that the rotating shaft 320 is rotatably connected to the fixing bracket 100 through the supporting rotating element 330. Specifically, each of the rolling elements 310 is provided with a fixing hole 311, and the second segment 322 is inserted into the fixing hole 311, so that each of the rolling elements 310 is fixedly connected to a corresponding one of the rotating shafts 320, so that the rolling elements 310 and the corresponding rotating shafts 320 can rotate synchronously. In this embodiment, the second segment 322 can be fixed in the fixing hole 311 by but not limited to interference fit and adhesive bonding.
In one embodiment, as shown in FIG. 10, the rotating shafts 320 includes a first segment 321 and two second segments 322, one end of the first segment 321 is connected to one of the second segments 322, and another end of the first segment 321 is connected to another one of the second segments 322. In such a structure, among the adjacent ones of the rolling elements 310, one of the rolling elements 310 is fixedly connected to the second segment 322 at one end of the corresponding one of the rotating shafts 320, and another one of the rolling elements 310 is fixedly connected to another end of the same one of the rotating shafts 320. The second segment 322 enables adjacent ones of the rolling elements 310 to be fixedly connected to the same one of the rotating shafts 320, so that all the rolling elements 310 can rotate synchronously.
In another embodiment, as shown in FIG. 11, each of the rotating shafts 320 includes a first segment 321 and a second segment 322, and one end of the first segment 321 is connected to the second segment 322. In such a structure, among adjacent ones of the rolling elements 310, one of the rolling elements 310 is fixedly connected to the second segment 322 of one of the rotating shafts 320, and another one the rolling elements 310 is fixedly connected to the second segment 322 of another one of the rotating shafts 320, so that adjacent ones of the rolling elements 310 are fixedly connected to different rotating shafts 320, so that each of the rolling elements 310 can rotate and operate independently. In this embodiment, since each rolling element 310 can rotate independently, when the flexible display panel 400 contacts the rolling element 310 and is displaced, each of the rolling elements 310 can generate different rotation angles, so as to better match displacement of the flexible display panel 400.
Specifically, a shape of the fixing hole 311 is adapted to a shape of the second segment 322, that is, a shape of the fixing hole 311 is the same as a shape of the second segment 322, and a cross-sectional shape of the second segment 322 can be circular. Of course, in order to increase an interlocking strength between the rotating shafts 320 and the rolling elements 310, the cross-sectional shape of the second segment 322 can also be in the shape of an ellipse, a triangle, a quadrilateral, or a pentagon. It should be noted that the above-mentioned cross-sectional shape refers to a cross-sectional shape cut by a plane perpendicular to the rotating shafts 320.
Specifically, as shown in FIG. 12, the circumferential surfaces of the rolling elements 310 are provided with a plurality of gear teeth 312, the back of the flexible display panel 400 is provided with a rack 410, and the gear teeth 312 are engaged and connected to the rack 410. In such a structure, the matching accuracy between the rolling elements 310 and the flexible display panel 400 can be improved, so as to control the movement of the flexible display panel 400 and prevent the flexible display panel 400 from slipping on the rolling elements 310.
