[0006] In some embodiments, the support member further includes an intermediate support sub-segment, and the two first support sub-segments are rotatably connected to both sides of the intermediate support sub-segment. In the flattened state, the first support sub-segments and the intermediate support sub-segments are arranged along the first direction.

[0007] In some embodiments, the moving member is slidably connected to the supporting member.

[0008] In some embodiments, one of the moving member and the supporting member has a sliding groove, and the other has a sliding member, and the sliding groove and the sliding member are in sliding engagement.

[0010] In some embodiments, the card slot includes a first inclined surface inclined relative to the first direction, and the card block has a second inclined surface for fitting with the first inclined surface.

[0011] In some embodiments, there are multiple card slots, and the multiple card slots are spaced apart along the first direction.

[0014] In some embodiments, the driving mechanism includes: a sensor, which is provided at one end of the first supporting sub-segment and is used to sense the rotation of the first supporting sub-segment; a driving device, which is electrically connected to the sensor and is used to drive the card block to engage or disengage with the card slot when the rotation of the first supporting sub-segment is detected.

[0035] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are set forth in order to provide a comprehensive understanding of the present application. However, it will be apparent to those skilled in the art that the present application can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the well-known structures and technologies are not shown in order to avoid unnecessary ambiguity in the present application; and, for clarity, the sizes of some structures may be exaggerated. In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0036] In addition, for the sake of understanding and ease of description, the size and thickness of each configuration shown in the figures are arbitrarily shown, but the concept of the present application is not limited thereto. In the figures, the thickness of layers, films, panels, and regions, etc., are exaggerated for clarity. In the figures, the thickness of some layers and regions is exaggerated for better understanding and ease of description.

[0037] It will be understood that when an element such as a layer, film, region, or substrate is described as being “on” another element, the element may be directly on the other element or intervening elements may be present. In contrast, when an element is described as being “directly on” another element, no intervening elements are present. Furthermore, throughout this specification, the term “on” a target element indicates positioning above or below the target element and does not necessarily mean positioning “at the upper side” based on the direction of gravity.

[0038] In addition, unless explicitly described to the contrary, the word “comprise” will be understood to imply the inclusion of stated elements but not the exclusion of any other elements.

[0039] To improve the portability of display devices, more and more display devices are being developed in the direction of being bendable. When the display panel is not in use, the display panel can be rotated along a predetermined axis to bend. In related technologies, there are cases where the display device is bent multiple times. During the first bend, the display panel of the display device is subjected to tensile stress. During the second bend, the corresponding crease is subjected to compressive stress, causing the crease to be abnormally buckled under the force of the second bend. After the display panel is flattened, the creases of the two bends, especially the crease of the second bend, will be arched. This problem seriously affects the flatness and display quality of the display panel.

[0040] In view of this, embodiments of the present application provide a support assembly and a display device. Various embodiments of the display panel and the display device will be described below with reference to the accompanying drawings.

[0041] The display device provided in the embodiment of the present application includes a supporting assembly and a display panel, and the display panel may be an organic light emitting diode (OLED) display panel.

[0042] like Figure 1 and Figure 2 As shown, the display module 100 provided according to an embodiment of the present application has a flattened state and a bent state, and the display module 100 includes a support member 110, a movable member 120, a display panel 140 and a locking mechanism 130. The support member 110 includes two first support sub-segments 112 that are rotatable with respect to each other. In the flattened state, the two first support sub-segments 112 are arranged along a first direction X. The movable member 120 is connected to the support member 110 and is movably arranged relative to the support member 110 along the first direction X. The display panel 140 is connected to the movable member 120 and can move along the first direction X with the movable member 120. The locking mechanism 130 is arranged between the first support sub-segment 112 and the movable member 120. The locking mechanism 130 is used to make the first support sub-segment 112 transition between a locked state fixed relative to the movable member 120 and a relatively movable unlocked state. The locking mechanism 130 is configured so that when one of the two first support sub-segments 112 rotates, the first support sub-segment 112 is in a locked state and the other first support sub-segment 112 is in an unlocked state.

[0043] If the two first support sub-segments 112 are rotatable relative to each other, the two first support sub-segments 112 can be directly rotatably connected, or connected through an intermediate connecting piece and respectively rotatably arranged relative to the intermediate connecting piece, both of which can achieve the purpose of the two first support sub-segments 112 being rotatable relative to each other.

[0044] Optionally, the two first supporting sub-segments 112 may be connected into a whole, or the two first supporting sub-segments 112 may be provided separately from each other.

[0045] Similarly, the moving member 120 can be a continuous integral structure, or the moving member 120 can include multiple sub-segments, which can be interconnected or not directly connected to each other.

[0046] Optionally, the moving member 120 may roll or slide along the first direction X relative to the supporting member 110 .

[0047] The display panel 140 is connected to the moving member 120 . The display panel 140 may be bonded to the moving member 120 , or the display panel 140 may be snapped to the moving member 120 .

[0048] The locking mechanism 130 is used to connect the moving member 120 and the supporting member 110 , and the number of the locking mechanisms 130 is at least two, and the two locking mechanisms 130 are respectively disposed between the two first supporting sub-segments 112 and the moving member 120 .

[0049] When the first support sub-segment 112 is in an unlocked state, the movable member 120 connected thereto can move relative to it along the first direction X. When the first support sub-segment 112 is in a locked state, the movable member 120 connected thereto cannot move relative to it along the first direction X.

[0050] When one of the two first support sub-segments 112 rotates, the locking mechanism 130 is actuated to fix the rotating first support sub-segment 112 and the movable member 120 to each other so that they are in a locked state. In this way, the rotating first support sub-segment 112 drives the display panel 140 to bend as it rotates. The other first support sub-segment 112 is in an unlocked state and can move relative to the movable member 120 along the first direction X toward the bending direction of the display panel 140. The display panel 140 then drives the movable member 120 to move relative to the other first support sub-segment 112. Since the display panel 140 will receive a certain amount of stress during the bending process, and since the display panel 140 can move along the first direction X, some of its internal stress can be released. This is conducive to reducing the internal stress of the display panel 140 during the bending process.

[0051] Since the two first supporting sub-segments 112 are arranged along the first direction X, during the rotation of the two first supporting sub-segments 112 , the display panel 140 moves in opposite directions along the first direction X. In this way, the display panel 140 bends at a different position each time, reducing the risk of damage to the display panel 140 caused by multiple bends at the same location.

[0052] Alternatively, the display module 100 can be bent once, or twice or more. In embodiments where the display module 100 is bent sequentially, the display module 100 can be bent by rotating either of the two first support sub-segments 112. In embodiments where the display module 100 is bent twice, the display module 100 can be bent after the two first support sub-segments 112 are bent sequentially.

[0053] The display module 100 provided in the embodiment of the present application is provided with a support member 110 including two first support sub-segments 112, and the first support sub-segments 112 are connected to the movable member 120 via a locking mechanism 130. The first support sub-segments are configured to be in a locked state, fixed relative to the movable member 120, during rotation, and in an unlocked state, movable relative to the movable member 120, when not rotating. By switching between the two states of the first support sub-segments 112, the display panel 140 can be moved along the first direction X during bending. In this way, the internal stress of the display panel 140 during bending can be released, reducing the internal stress of the display panel 140 in the bending state and improving the smoothness of the bending movement of the display panel 140. In addition, the two first support sub-members move in opposite directions during their respective rotations, so that the crease of the display panel 140 changes each time it bends, reducing the risk of fatigue damage caused by cyclic bending and flattening at the same location. Therefore, the display module 100 provided in the embodiment of the present application can improve the reliability of the display panel 140 and reduce the possibility of damage to the display panel 140.

[0054] like Figure 2 As shown, in some embodiments, the support member 110 also includes an intermediate support sub-segment 111, and two first support sub-segments 112 are rotatably connected to both sides of the intermediate support sub-segment 111. In the flattened state, the first support sub-segments 112 and the intermediate support sub-segment 111 are arranged along the first direction X.

[0055] Optionally, the support member 110 may include one intermediate support sub-segment 111 , or may include multiple intermediate support sub-segments 111 , and two adjacent intermediate support sub-segments 111 may be arranged to rotate relative to each other so that the display panel 140 can be bent at the corresponding two intermediate support sub-segments 111 .

[0056] The first supporting sub-segment 112 and the middle supporting sub-segment 111 may be integrally formed, or they may be formed separately and then rotatably connected together via an intermediate piece.

[0057] With such an arrangement, the display panel 140 can be bent twice by respectively rotating the two first supporting sub-segments 112 relative to the middle supporting sub-segment 111 , that is, the display panel 140 can be folded into three parts in the end.

[0058] During the rotation of one of the first support sub-segments 112 relative to the middle support sub-segment 111, the movable member 120 connected thereto rotates along with the first support sub-segment 112, driving the display panel 140 connected thereto to bend. During the bending of the display panel 140, the movable member 120 is driven to move relative to the support member 110 along the first direction X toward the deformation direction of the display panel 140, thereby reducing the deformation of the display panel 140 and reducing the tensile stress on the display panel 140 in the bent state. When the other first support sub-segment 112 rotates relative to the middle support sub-segment 111, the corresponding first support sub-segment 112 is in a locked state, while the first support sub-segment 112 that has completed bending is in an unlocked state. During the rotation of the first supporting sub-segment 112, the movable member 120 and the display panel 140 connected thereto are bent together, and the display panel 140 can still move along the bending direction relative to the supporting member 110 to reduce the stress borne by the display panel 140. In this way, during the rotation of the first supporting sub-segment 112 on the other side, the other side of the display panel 140 will be subjected to force more smoothly during the bending process, thereby reducing the buckling phenomenon of the display panel 140 after being flattened.

[0059] That is to say, in the display module 100 provided by the embodiment of the present application, when any one of the first support sub-segments 112 rotates, the movable member 120 connected thereto and one side of the display panel 140 are driven to bend together, and the movable member 120 can move relative to the support member 110 along the bending direction of the display panel 140, thereby reducing the internal stress borne by the display panel 140 during the first bending. During the second bending of the display panel 140, the first support sub-segment 112 on the other side rotates relative to the middle support sub-segment 111, and drives the movable member 120 connected thereto and the other side of the display panel 140 to move toward the bending direction of the display panel 140, thereby also reducing the internal stress borne by the display panel 140 during the second bending. Since the internal stress of the display panel 140 is relatively small during the first bending, the buckling stress of the display panel 140 is relatively small during the second bending, thereby effectively reducing the risk of buckling of the display panel 140 after being flattened.

[0060] Therefore, by setting the intermediate support sub-segment 111, the display panel 140 can be bent twice, and during the two bending processes, the display panel 140 can move relative to the support member 110 along the first direction X, which is beneficial to reducing the internal stress that the display panel 140 is subjected to during the bending process, making the force on the display panel 140 smoother, and reducing the risk of buckling of the display panel 140 when it is flattened after being bent.

[0061] In some embodiments, the moving member 120 is slidably connected to the supporting member 110 .

[0062] The moving member 120 is slidably connected to the supporting member 110. When the display panel 140 is bent, the moving member 120 slides relative to the supporting member 110. The moving member 120 is slidably connected to the supporting member 110, which is simple in connection and reliable in operation.

[0063] Optionally, the specific structure of the sliding connection between the moving member 120 and the supporting member 110 can be selected according to actual conditions and is not limited here.

[0064] like Figure 1 、 Figure 3 and Figure 4 In some embodiments, one of the moving member 120 and the supporting member 110 has a sliding groove 110 a , and the other has a sliding member 120 a , and the sliding groove 110 a and the sliding member 120 a are slidably matched.

[0065] The sliding groove 110a and the sliding member 120a cooperate with each other. On the premise that the moving member 120 can slide relative to the supporting member 110, the sliding groove 110a provides a certain guiding effect for the sliding of the sliding member 120a to guide the sliding direction of the moving member 120 relative to the supporting member 110, thereby reducing the risk of lateral deviation of the display panel 140 during the bending process.

[0066] As shown in FIG5 , in some embodiments, the locking mechanism 130 includes a drive mechanism 133 and a slot 131 and a block 132 that can cooperate with each other. One of the slot 131 and the block 132 is provided in the first support sub-segment 112, and the other is provided in the movable member 120. The drive mechanism 133 connects at least one of the slot 131 and the block 132 and is used to drive the engagement or disengagement of the slot 131 and the block 132. The slot 131 and the block 132 are configured such that when they engage with each other, the corresponding first support sub-segment 112 is in a locked state, and when they disengage from each other, the corresponding first support sub-segment 112 is in an unlocked state.

[0067] Specifically, when the first support sub-segment 112 rotates, the corresponding locking slot 131 and the locking block 132 of the locking mechanism 130 cooperate with each other to lock the corresponding first support sub-segment 112, causing the first support sub-segment 112 to bend the movable member 120 and one side of the display panel 140. Conversely, when the first support sub-segment 112 does not rotate relative to the middle support sub-segment 111, the locking slot 131 and the locking block 132 disengage from each other, and the corresponding first support sub-segment 112 is unlocked, allowing the movable member 120 that cooperates with it to move relative to the first support sub-segment 112.

[0068] The engagement and disengagement of the slot 131 and the block 132 can be achieved by providing a driving mechanism 133 and a connecting rod mechanism, and connecting the intermediate support sub-segment 111 and the block 132 through the connecting rod mechanism. When the first support sub-segment 112 rotates, the connecting rod mechanism is driven to rotate, thereby driving the block 132 to move, so that the block 132 and the slot 131 are engaged with each other. Of course, the driving mechanism 133 can also be provided to include a sensing device to sense the rotation of the first support sub-segment 112, thereby controlling the engagement and disengagement of the slot 131 and the block 132. For example, when the sensing device senses the rotation of the first support sub-segment 112, the driving mechanism 133 is used to drive the slot 131 and the block 132 to engage with each other. Otherwise, the driving mechanism 133 is used to drive the slot 131 and the block 132 to disengage from each other.

[0069] It can be understood that the first supporting sub-segment 112 is placed in a locked state or an unlocked state by the engagement or disengagement of the engagement slot 131 and the engagement block 132 , which has a simple structure and reliable operation.

[0070] Please continue reading Figure 5 In some embodiments, the slot 131 includes a first inclined surface 131 a tilted relative to the first direction X, and the block 132 includes a second inclined surface 132 a for fitting with the first inclined surface 131 a.

[0071] The first inclined surface 131a and the second inclined surface 132a can fit together, and their inclination angles relative to the first direction X are similar. In the process of the engagement between the slot 131 and the block 132, the first inclined surface 131a and the second inclined surface 132a are close to and fit together.

[0072] After the moving member 120 moves relative to the first supporting sub-segment 112 along the first direction X, the slot 131 and the block 132 are offset by a certain distance along the first direction X, and the first inclined surface 131a and the second inclined surface 132a are provided to cooperate with each other. After the slot 131 and the block 132 are offset by a certain distance, the slot 131 and the block 132 can still cooperate with each other, which is beneficial to increase the area of ​​the mutual cooperation between the slot 131 and the block 132, thereby improving the cooperation stability between the slot 131 and the block 132.

[0073] Please continue to refer to 5. In some embodiments, the plurality of slots 131 are arranged along the first direction X at intervals.

[0074] A plurality of slots 131 are arranged at intervals along the first direction X. When the moving member 120 moves relative to the first supporting sub-segment 112 along the first direction X, the block 132 cooperates with any slot 131 to lock the first supporting sub-segment 112.

[0075] Therefore, multiple slots 131 are set. During the movement of the movable member 120 relative to the first supporting sub-segment 112 cooperating with it, there is always a slot 131 that can cooperate with the block 132 to achieve the locking of the first supporting sub-segment 112 and the movable member 120. During the rotation of the first supporting sub-segment 112, it is beneficial to improve the reliability of the cooperation between the block 132 and the slot 131.

[0076] In some embodiments, the distance between two adjacent slots 131 is less than or equal to mm.

[0077] For example, the distance between any two adjacent card slots 131 may be mm, 0.8 mm, 0.01 mm, or 0.01 mm.

[0078] Such a configuration is conducive to further ensuring that the slot 131 can cooperate with the block 132 at any position during the process of the movable member 120 moving relative to the first supporting sub-segment 112 along the first direction X, further improving the reliability of the cooperation between the slot 131 and the block 132, and realizing the locking of the first supporting sub-segment 112 and the movable member 120.

[0079] Please continue reading Figure 5 In some embodiments, the slot 131 is provided on a side of the movable member 120 facing the first support sub-segment 112. The driving mechanism 133 includes a connecting rod 1331 and a slider 1332. One end of the connecting rod 1331 is connected to the support member 110, and the other end is connected to one first support sub-segment 112. The connecting rod 1331 can rotate relative to the other first support sub-segment 112 along with the first support sub-segment 112. The slider 1332 is connected to the end of the connecting rod 1331 connected to the first support sub-segment 112. The block 132 is connected to the slider 1332. The slider 1332 is configured to move when the first support sub-segment 112 rotates, so that the slot 131 and the block 132 cooperate with each other.

[0080] Optionally, one end of the connecting rod 1331 is connected to a first support sub-segment 112, and the other end can be connected to the middle support sub-segment 111, or other parts of the support member 110, so that when the first support sub-segment 112 rotates, the connecting rod 1331 rotates accordingly.

[0081] By reasonably setting the length of the connecting rod 1331 and the position of the slider 1332 relative to the connecting rod 1331, during the rotation of the first support sub-segment 112, the connecting rod 1331 rotates and drives the slider 1332 to move relative to the first support sub-segment 112. The slider 1332 then drives the block 132 to slide to achieve cooperation with the slot 131.

[0082] The driving mechanism 133 is provided to include a connecting rod 1331 and a slider 1332. When the first supporting sub-segment 112 is rotated, the block 132 moves relative to the first supporting sub-segment 112 to achieve cooperation with the slot 131. At the same time, the connecting rod 1331 has a simple structure and reliable operation. During the rotation of the first supporting sub-segment 112, it is beneficial to improve the reliability of the locking of the first supporting sub-segment 112 and the moving member 120.

[0083] like Figure 6 As shown, in some embodiments, the driving mechanism 133 includes a sensor 1333 and a driving device. The sensor 1333 is disposed at one end of the first supporting sub-segment 112 and is used to sense the rotation of the first supporting sub-segment 112. The driving device is electrically connected to the sensor 1333 and is used to drive the locking block 132 to engage with the locking slot 131 when the rotation of the first supporting sub-segment 112 is detected.

[0084] The driving device is connected to the clamping block 132 and is used to drive the clamping block 132 to move relative to the first supporting sub-segment 112 to achieve the engagement or disengagement of the clamping block 132 with the clamping slot 131 .

[0085] The sensor 1333 is used to sense the rotation of the first support sub-segment 112. When the sensor 1333 senses the rotation of the first support sub-segment 112 relative to the intermediate support sub-segment 111 or other parts of the support member 110, it sends a signal to the driving device, which activates the driving device to drive the clamping block 132 to move, thereby achieving the engagement of the clamping block 132 with the clamping slot 131. When the sensor 1333 does not sense the rotation of the first support sub-segment 112 relative to the intermediate support sub-segment 111 or other parts of the support member 110, the driving device does not activate, or the driving device activates in the opposite direction, thereby achieving the disengagement of the clamping block 132 from the clamping slot 131.

[0086] The specific structure of the driving device is not limited. For example, the driving device may be a lifting mechanism, or a cam mechanism, etc.

[0087] The driving mechanism 133 includes a sensor 1333 and a driving device, which can achieve locking and unlocking of the first supporting sub-segment 112 and the moving member 120 while simplifying the overall structure of the display module 100 .

[0088] In some embodiments, the sensor 1333 includes an angle sensor 1333 and / or a displacement sensor 1333 .

[0089] Optionally, the sensor 1333 may include only the angle sensor 1333 , or only the displacement sensor 1333 . Of course, it may also include both the angle sensor 1333 and the displacement sensor 1333 .

[0090] The angle sensor 1333 is used to sense changes in the angle of the first support sub-segment 112 relative to the intermediate support sub-segment 111 or other parts of the support member 110, and the displacement sensor 1333 is used to sense changes in the displacement of the first support sub-segment 112 relative to the intermediate support sub-segment 111 or other parts of the support member 110. It will be understood that when the first support sub-segment 112 rotates relative to the intermediate support sub-segment 111 or other parts of the support member 110, both the displacement and angle of the first support sub-segment 112 relative to the intermediate support sub-segment 111 or other parts of the support member 110 will change. Therefore, providing the sensor 1333, including either the angle sensor 1333 or the displacement sensor 1333, can sense the rotation of the first support sub-segment 112 relative to the intermediate support sub-segment 111 or other parts of the support member 110.

[0091] Please continue reading Figure 6 In some embodiments, the driving device includes an electromagnet 1334, one of the slot 131 and the block 132 is connected to the electromagnet 1334, and the other has a magnetic element. The electromagnet 1334 is configured to attract the magnetic element when powered on.

[0092] Specifically, when sensor 1333 senses the rotation of the first support sub-segment 112, it transmits a signal to the control unit to energize electromagnet 1334. Once energized, electromagnet 1334 attracts the magnetic element, achieving mutual engagement between the slot 131 and the block 132. Otherwise, if sensor 1333 does not sense the rotation of the first support sub-segment 112, electromagnet 1334 is not energized and does not attract the magnetic element. Consequently, the slot 131 and the block 132 become disengaged, allowing the movable member 120 to move relative to the first support sub-segment 112.

[0093] The driving device includes an electromagnet 1334, and one of the slot 131 and the block 132 is connected to the electromagnet 1334, while the other has a magnetic element. When the first support sub-segment 112 rotates, the electromagnet 1334 is energized and attracts the magnetic element, thereby achieving engagement between the slot 131 and the block 132, and locking the first support sub-segment 112. Otherwise, the electromagnet 1334 is de-energized, disengaging the slot 131 and the block 132, and unlocking the first support sub-segment 112. The structure is simple and the operation is reliable.

[0094] like Figure 2 and Figure 5 As shown, in some embodiments, the first support sub-segment 112 and the adjacent intermediate support sub-segment 111 respectively have a first gear 1121 and a second gear 1111 that are meshed with each other, and the first gear 1121 and the second gear 1111 rotate relative to each other to drive the two adjacent first support sub-segments 112 and the intermediate support sub-segment 111 to rotate relative to each other.

[0095] During the rotation of the first support sub-segment 112 relative to the intermediate support sub-segment 111, the first gear 1121 and the second gear 1111 rotate relative to each other. This arrangement still allows the first support sub-segment 112 to rotate relative to the intermediate support sub-segment 111. Furthermore, through the cooperation between the first gear 1121 and the second gear 1111, the rotation of the first support sub-segment 112 relative to the intermediate support sub-segment 111 is smoother, and the risk of interference between the structures of the first support sub-segment 112 and the intermediate support sub-segment 111 is reduced during the rotation of the first support sub-segment 112 relative to the intermediate support sub-segment 111.
