[0001] The present application relates to the technical field of electronic devices, and in particular to a foldable display module and a display device. BACKGROUND

[0002] At present, foldable screens are widely used in electronic devices, which are convenient for storage of the electronic devices. After the foldable screen is bent for a long time, the bending position is prone to a concave phenomenon. The non-bending area is connected with a hinge in the foldable screen for opening and closing. When the foldable screen is unfolded after the bending position is concave, the connection between the bending position and the non-bending area abuts against the hinge, causing slight convexity on both sides of the bending position and connecting with the concave bending position. After the foldable screen is unfolded, an M-shaped fold is presented, which further affects the display effect of the foldable screen. SUMMARY

[0053] For a better understanding of the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0054] are described.

[0055] It should be clear that the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0056] The terms used in the embodiments of the present application are merely for the purpose of describing particular embodiments and are not intended to limit the present application. The singular forms "a", "an" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0057] It should be understood that the term "and / or" used herein only describes an association relationship of associated objects, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. In addition, the character " / " herein generally represents that the front and rear associated objects are in an "or" relationship.

[0058] It should be noted that the "up", "down", "left", "right" and other directional words described in the embodiments of the present application are described from the angle shown in the drawings, and should not be understood as a limitation on the embodiments of the present application. In addition, it should be understood in the context that when referring to an element connected to another element "on" or "under", it can be directly connected to another element "on" or "under", or indirectly connected to another element "on" or "under" through an intermediate element.

[0059] As Figure 1As shown, the foldable display in the related art includes a display screen 1' and a folding support 2', the display screen 1' is installed on one side of the folding support 2', and the folding support 2' can be folded to the side where the display screen 1' is arranged. The folding support 2' includes a hinge structure 21', and a support piece 22' is arranged at both ends of the hinge structure 21', the hinge structure 21' can change the angle between the two support pieces 22', the display screen 1' includes a folding part 11' and a non-folding part 12', as shown, the non-folding part 12' is located on both sides of the folding part 11', the non-folding part 12' overlaps with the support piece 22' and is fixed to the folding support 2', and the folding part 11' overlaps with the hinge structure 21'. When the display screen 1' is unfolded, the non-folding part 12' is attached to the support piece 22', and the hinge structure 21' cannot provide support to the folding part 11' of the display screen 1'. After the display screen 1' is folded for a long time, the display screen 1' will have the inertia of folding recess when unfolded, causing the folding part 11' to recess towards the folding support 2'. At the same time, due to the recess of the folding part 11', the edge of the support piece 22' will generate an action force on the position where the folding part 11' and the non-folding part 12' intersect, in a direction away from the folding support 2', causing the position where the folding part 11' and the non-folding part 12' intersect to deform. After the display screen 1' is folded for many times, the folding screen 1' will form an "M" type fold mark, affecting the display effect of the display screen 1'.

[0060] As shown in Figure 2 and Figure 3 The embodiment of the present application provides a foldable display module, which comprises a flexible screen 1, a rotating piece 2 and a support assembly 3, the rotating piece 2 is connected with the flexible screen 1, and the support assembly 3 is connected with the rotating piece 2. The flexible screen 1 comprises a folding area 11, and the support assembly 3 overlaps with the folding area 11 along the direction of the flexible screen 1 pointing to the support assembly 3. The support assembly 3 comprises a first support piece 31 and a second support piece 32, one end of the first support piece 31 is connected with the rotating piece 2, and the other end is abutted with the second support piece 32. When the foldable display module is unfolded, the rotating piece 2 drives the first support piece 31 to move along the length direction X of the foldable display module, and the first support piece 31 drives the second support piece 32 to move along the thickness direction Z of the foldable display module, towards the side close to the folding area 11.

[0061] The length direction X of the foldable display module is parallel to the plane where the flexible screen 1 is located in the unfolded state.

[0062] Optionally, along the thickness direction Z of the foldable module, the flexible screen 1 comprises a light-out side 13 and a backlight side 14, the light-out side 13 is used to display the content in the flexible screen 1 to the user, and the backlight side 14 faces the rotating piece 2 and the support assembly 3. The flexible screen 1 comprises a bending area 11 and a non-bending area 12, the rotating piece 2 is connected with the non-bending area 12 and is used to drive the flexible screen 1 to unfold or fold, when the foldable display module is folded, the rotating piece 2 can drive the flexible screen 1 to fold in the direction of the light-out side 13, and when the foldable display module is unfolded, the support assembly 3 can abut against the bending area 11.

[0063] The rotating piece 2 rotates with the non-bending area 12 of the flexible screen 1 during the unfolding process of the foldable display module, and one end abutting against the first support piece 31 can drive the first support piece 31 to move along the length direction X of the foldable display module, so that the first support piece 31 drives the second support piece 32 to move along the thickness direction Z of the foldable display module until abutting against the bending area 11. The support assembly 3 is arranged on the backlight side of the bending area 11 of the flexible screen 1 and abuts against the backlight side of the bending area 11 when the foldable display module is unfolded, which reduces the possibility of the bending area 11 being concave, and in turn reduces the possibility of the rotating piece 2 generating an action force on the bending area 11 and the non-bending area 12 in the opposite direction of the concave direction, which is beneficial to improve the flatness of the flexible screen 1 when unfolded and improve the display effect of the foldable display module.

[0064] As shown in Figure 4 In a possible embodiment, the second support piece 32 comprises a first guide part 321, which is inclined away from the first support piece 31 along the direction in which the flexible screen 1 points to the support assembly 3, and the first support piece 31 abuts against the first guide part 321.

[0065] Optionally, along the thickness direction Z of the foldable display module, the cross section of the first support piece 31 can be a rectangular shape or other shapes with edges, and the edge of the first support piece 31 abuts against the first guide part 321, so that when the first support piece 31 moves along the length direction X of the foldable display module to the direction close to the second support piece 32, the first support piece 31 can slide along the inclined surface of the first guide part 321 relative to the second support piece 32.

[0066] The first support 31 moves towards the side close to the second support 32 along the length direction X of the foldable display module, and the edge of the first support 31 abuts against the first guide part 321 in the second support 32, which can decompose the force applied by the first support 31 to the second support 32 along the thickness direction Z of the foldable display module, so that the first support 31 moving along the length direction X of the foldable display module can drive the second support 32 to move along the thickness direction Z of the foldable display module. In the direction in which the flexible screen 1 points to the support assembly 3, the first guide part 321 is inclined away from the first support 31, which can limit the movement direction of the second support 32, so that the second support 32 moves towards the direction close to the bending area 11 to abut against the bending area 11. When the first support 31 moves away from the second support 32, the second support 32 moves away from the bending area 11 under the action of gravity, so that the first support 31 moves along the first guide part 321.

[0067] As shown in Figure 4 In a possible embodiment, the second support 32 further includes a limiting part 322, which protrudes from the first guide part 321, and abuts against the first support 31 when the second support 32 moves to the preset position.

[0068] Optionally, the cross section of the limiting part 322 along the thickness direction Z of the foldable display module can be rectangular, rhombic or other shapes, which is not limited herein, and the limiting part 322 can abut against the side wall of the first support 31 when the first support 31 moves along the first guide part 321 to the preset position. The limiting part 322 can be integrally formed with the second support 32, or fixed to the first guide part 321 by bonding, welding or other methods, so that the limiting part 322 protrudes from the first guide part 321.

[0069] When the foldable display module is unfolded, the first support member 31 moves along the length direction X of the foldable display module, and the first support member 31 moves along the first guide portion 321, so that the second support member 32 moves in the direction close to the bending area 11. After the first support member 31 moves to the preset position, the foldable display module is in an unfolded state and / or the second support member 32 abuts against the bending area 11. If the first support member 31 continues to move along the length direction X of the foldable display module after moving to the preset position, the first support member 31 will be separated from the first guide portion 321, causing the second support member 32 to be separated from the first support member 31, or an acting force is generated on the bending area 11, causing the bending area 11 to be deformed. The limiting member 322 is arranged on the first guide portion 321, and the second support member 32 abuts against the limiting member 322 after moving to the preset position. The limiting member 322 can limit the relative position between the first support member 31 and the second support member 32, reducing the possibility of the second support member 32 being separated from the first support member 31 or the possibility of the bending area 11 being deformed, and improving the reliability of the support assembly 3.

[0070] As shown in FIGS. 1, 2 and 3, in a possible embodiment, the first support member 31 is provided with a second guide portion 311, and the second guide portion 311 can abut against the first guide portion 321. Figure 5 and Figure 6 As shown in FIGS. 1, 2 and 3, in a possible embodiment, the first support member 31 is provided with a second guide portion 311, and the second guide portion 311 can abut against the first guide portion 321.

[0071] Alternatively, the cross section of the first support member 31 and the cross section of the second support member 32 can be rectangular or other shapes along the thickness direction of the foldable display module, which is not limited herein, and the first guide portion 321 and the second guide portion 311 that can abut against each other are arranged on the side where the two are in contact with each other. At this time, the limiting member 322 can be located on the first guide portion 321 and abut against the first support member 31 after the first support member 31 moves to the preset position, limiting the relative position between the first support member 31 and the second support member 32, or the limiting member 322 can be located on the second guide portion 311 and abut against the second support member 32 after the first support member 31 moves to the preset position, limiting the relative position between the first support member 31 and the second support member 32. The second guide portion 311 is arranged on the first support member 31 and abuts against the first guide portion 321, which can increase the contact area between the first support member 31 and the second support member 32, and improve the stability of the first support member 31 in the process of pushing the second support member 32 to move.

[0072] As shown in FIGS. 1, 2 and 3, in a possible embodiment, the first support member 31 is provided with a second guide portion 311, and the second guide portion 311 can abut against the first guide portion 321. Figure 7As shown, in one possible embodiment, the first support member 31 is provided with a second guide portion 311. Along the direction from the flexible screen 1 to the support assembly 3, the second guide portion 311 is inclined towards the second support member 32. The side of the second support member 32 abuts against the second guide portion 311. The second support member 32 does not have a first guide portion 321; its cross-section can be rectangular, with one corner abutting against the second guide portion 311. When the first support member 31 moves along the foldable display module, the second support member 32 moves along the second guide portion 311. A limiting member 322 is located at the end of the second guide portion 311 near the flexible screen 1. After the first guide portion 321 moves to a preset position, the limiting member 322 can abut against the second support member 32 to limit the relative position between the first support member 31 and the second support member 32, reducing the possibility of the second support member 32 detaching from the first support member 31.

[0073] like Figure 2 and Figure 3 As shown, in one possible embodiment, the rotating member 2 is connected to the non-bending area 12 of the flexible screen 1, and a bending part 21 is provided at one end near the bending area 11. One end of the bending part 21 is connected to the rotating member 2, and the other end can be connected to the first support member 31. When the foldable display module is unfolded, the movement trajectory of the end of the bending part 21 near the first support member 31 is arc-shaped.

[0074] When the foldable display module is unfolded, the rotating component 2 can drive the bending portion 21 to rotate. Optionally, the bending portion 21 can be an arc-shaped structure and abut against the first support component 31. The movement trajectory of the end of the bending portion 21 near the first support component 31 is arc-shaped, such as... Figure 8 As shown, the dashed line represents the relative position of the bending part 21 and the support component 3 when the foldable display module is in the folded state, and the solid line represents the position of the bending part 21 and the support component 3 when the foldable display module is in the unfolded state. Therefore, the first support member 31 can be pushed to move along the length direction X of the foldable display module.

[0075] The bending part 21 is used to connect the rotating part 2 and the bending part 21. During the unfolding process of the foldable display module, the rotating part 2 can push the first support 31 to move along the length direction X of the foldable display module through the bending part 21. The movement distance of the first support 31 can be controlled by the rotation angle of the rotating part 2, and then the movement distance of the second support 32 along the thickness direction Z of the foldable display module can be controlled.

[0076] like Figures 2 to 7 As shown, in one possible embodiment, the foldable display module includes at least two sets of support components 3.

[0077] Optionally, the two groups of support assemblies 3 are symmetrically arranged about a bending axis of the bending area 11 in the flexible screen 1, the bending axis is a straight line where the deformation amplitude of the bending area 11 is the largest, and the rotating member 2 and the bending part 21 are arranged on the side away from each other of the two groups of support assemblies 3, for driving the first support 31 in the two groups of support assemblies 3.

[0078] When the foldable display module is fully unfolded, the non-bending areas 12 on both sides of the bending area 11 are unfolded to both sides, so that the included angle of the flexible screen 1 is 180° or close to 180°, and the two groups of support assemblies 3 are driven by the rotating member 2 and the bending part 21 to move the two second supports 32 towards the bending area 11, and the movement distance of the two first supports 31 is consistent, and the movement distance of the two second supports 32 is also consistent, so that the support of the two second supports 32 to the bending area 11 is consistent, which is beneficial to improve the flatness of the flexible screen 1. When one side of the foldable display module is unfolded, the included angle of the flexible screen 1 is 90°, and the support assembly 3 on the unfolded side of the foldable display module is driven by the rotating member 2 and the bending part 21 to enable the first support 31 on the unfolded side of the foldable display module to move in the direction close to the bending area 11, and the first support 31 on the other side remains in the original position, so that the bending area 11 can be supported when the foldable display module is unfolded to 90°, and the possibility of creases in the bending area 11 is reduced.

[0079] As shown in Figures 2 to 7 In a possible embodiment, an elastic member 33 is arranged between the two groups of support assemblies 3, and the two ends of the elastic member 33 are connected with the second support 32 in the two groups of support assemblies 3, respectively.

[0080] Optionally, the elastic member 33 can be a spring, rubber, memory alloy or the like structure or material, which is not limited here, and can only push the two first supports 31 to move in the direction away from each other during folding of the foldable module. When the foldable display module is unfolded, the rotating member 2 pushes the two first supports 31 to move in the direction close to each other, and the first support 31 can compress the elastic member 33 while pushing the second support 32, so that the elastic member 33 is elastically deformed. When the foldable display module is folded, the end of the rotating member 2 abutting against the first support 31 moves away from the first support 31, at this time, the elastic force of the elastic member 33 can push the two first supports 31 to move in the direction away from each other, so that the second support 32 moves away from the bending area 11 under the action of gravity.

[0081] As shown in Figures 9 to 11As shown in the possible embodiment, the support assembly 3 further comprises a housing 4, the housing 4 is provided with a receiving cavity 41 and a guide channel 42, the guide channel 42 is in communication with the receiving cavity 41, the first support 31 is located in the receiving cavity 41, and the second support 32 is located in the guide channel 42 and can move along the guide channel 42.

[0082] Optionally, the receiving cavity 41 extends along the length direction X of the foldable display module and can penetrate through the housing 4, so that the first support 31 located in the receiving cavity 41 can move along the length direction X of the foldable display module in the receiving cavity 41, and the rotating piece 2 can extend into the receiving cavity 41 from both sides of the housing 4 and abut against the first support 31. The guide channel 42 extends along the thickness direction Z of the foldable display module, the second support 32 is located in the guide channel 42 and can move along the thickness direction Z of the foldable display module in the guide channel 42. One side of the guide channel 42 is in communication with the receiving cavity 41, and the other side can penetrate through the housing 4 and face one side of the flexible screen 1, so that the second support 32 can abut against the bending area 11.

[0083] The receiving cavity 41 penetrates through the housing 4, so that the rotating piece 2 can abut against the first support 31 and facilitate pushing the first support 31, and the receiving cavity 41 can also limit the movement direction of the first support 31, so that the first support 31 moves along the length direction X of the foldable display module. When the foldable display module is in the bending state, the second support 32 is located inside the housing 4, when the foldable display module is unfolded, the first support 31 pushes the second support 32 to move in the direction close to the bending area 11, and the guide channel 42 can limit the movement direction of the second support 32, so that the second support 32 can move along the thickness direction Z of the foldable display module to protrude from the housing 4 and support the bending area 11. The receiving cavity 41 and the guide channel 42 are in communication with each other, so that the first support 31 and the second support 32 can cooperate with each other and facilitate driving the second support 32 to move along the thickness direction Z of the foldable display module.

[0084] As shown in the possible embodiment, Figure 2 , Figure 3 , Figure 10 and Figure 11 , in a possible embodiment, the housing 4 comprises a stop block 5, the stop block 5 protrudes from the outer surface of the housing 4, and the rotating piece 2 can be connected with the stop block 5.

[0085] Optionally, the stop block 5 protrudes from both sides of the housing 4 along the length direction X of the foldable display module, and the lower surface of the stop block 5 is in the same plane as the inner wall of the receiving cavity 41, and when the foldable display module is unfolded, the bending part 21 can abut against the stop block 5. The connection mode of the stop block 5 and the housing 4 can be integrally formed, bonded, welded, etc., which is not limited herein, as long as the stop block 5 is fixed to the outer surface of the housing 4.

[0086] In the process of unfolding the foldable display module, the rotating member 2 rotates with the flexible screen 1, wherein the contour of the bending part 21 is arc-shaped, and in the process of rotating the rotating member 2, the movement track of the end of the bending part 21 close to the first supporting member 31 is arc-shaped. In the process of pushing the first supporting member 31 to move along the length direction X of the foldable display module, the first supporting member 31 also moves along the thickness direction Z of the foldable display module. If the stopper 5 is not arranged, the end of the bending part 21 abutting against the first supporting member 31 is prone to move along the side wall of the shell 4 and thus deviate from the first supporting member 31, which results in that the first supporting member 31 cannot be pushed to move along the length direction X of the foldable display module. The stopper 5 protrudes from the outer surface of the shell 4, which can limit the movement of the bending part 21 along the side wall of the shell 4, thereby reducing the possibility that the bending part 21 deviates from the first supporting member 31, and making the process of pushing the first supporting member 31 by the bending part 21 more reliable.

[0087] In a possible embodiment, the stopper 5 can also be fixedly connected with the bending part 21, and the end of the stopper 5 away from the bending part 21 can extend into the accommodating cavity 41. In the process of unfolding the foldable display module, the stopper 5 can move with the end of the bending part 21 close to the first supporting member 31, and the stopper 5 is located in the accommodating cavity 41 and abuts against the inner wall of the accommodating cavity 41, which reduces the possibility that the bending part 21 deviates from the first supporting member 31 and moves along the side wall of the shell 4.

[0088] As shown in FIGS. 1, 2 and 3, the rotating member 2 can be fixedly connected with the first supporting member 31, and the first supporting member 31 can be arranged in the accommodating cavity 41 of the shell 4. Figure 10 Figure 11 As shown in FIGS. 1, 2 and 3, in a possible embodiment, the shell 4 comprises a guide rail 43, and the guide rail 43 is located in the accommodating cavity 41, and the first supporting member 31 can move along the guide rail 43.

[0089] The guide rail 43 is arranged along the length direction X of the foldable display module, and the first supporting member 31 moves along the guide rail 43, which can limit the movement track of the first supporting member 31 and reduce the possibility that the first supporting member 31 shakes in the accommodating cavity 41, thereby improving the stability of the movement of the first supporting member 31, and reducing the possibility that the first supporting member 31 rubs against the side wall of the accommodating cavity 41, which reduces the driving force required by the first supporting member 31 in the movement process and facilitates the pushing of the first supporting member 31 by the rotating member 2.

[0090] As shown in FIGS. 1, 2 and 3, in a possible embodiment, the shell 4 comprises a guide rail 43, and the guide rail 43 is located in the accommodating cavity 41, and the first supporting member 31 can move along the guide rail 43.
