[0034] Please refer to Figure 1 and Figure 2The display device provided in the present application has a folding state and a flat state, and comprises a flexible display panel 1 and a supporting assembly 2. The display panel 1 comprises a bending area 101 and non-bending areas 102 located on both sides of the bending area 101. The number of the supporting assemblies 2 is two, and each supporting assembly 2 is arranged on one side of each non-bending area. The supporting assembly 2 comprises a fixed part 201 and a magnetic part 202. The fixed part 201 is arranged on the surface of the non-bending area 102 to support the flexible display panel 1. The magnetic part 202 is movably connected to the fixed part 201 in the direction from the non-bending area 102 to the bending area 101. In the flat state, the magnetic properties of the two magnetic parts 202 are different and located on one side of the bending area 101 to support the bending area 101.

[0035] In the embodiments provided in the present application, the display device has a folding state and a flat state, and comprises a flexible display panel 1 and a supporting assembly 2. The flexible display panel 1 can realize the transformation of the display device between the folding state and the flat state through the bending area 101 thereof. The fixed part 201 of the supporting assembly 2 can provide good support for the non-bending area 102 of the flexible display panel 1, and the magnetic part 202 of the supporting assembly 2 is movably connected with the fixed part 201. As shown in the figure, in the flat state, the magnetic part 202 can be moved from the non-bending area 102 to the bending area 101 of the flexible display panel 1 and support the bending area 101. In this way, the collapse and indentation caused by the lack of support of the bending area 101 can be effectively improved, and the service life of the display panel and the user experience can be improved. Figure 2

[0036] The type of the display device is not limited, and the display device may, for example, be a display screen of a foldable mobile phone or a display screen of a foldable tablet computer.

[0037] Figure 1 The boundary between the bending area 101 and the non-bending area 102 is shown by a dashed line in the figure, and the dashed line does not constitute a limitation on the structure of the flexible display panel 1.

[0038] In some optional embodiments, the magnetic part 202 is reciprocally movably connected to the fixed part 201 in the direction from the non-bending area 102 to the bending area 101. In the folding state, the magnetic properties of the two magnetic parts 202 are the same and located on one side of the non-bending area 102.

[0039] Optionally, the display device can be an inner folding type or an outer folding type, as shown in the figures. Figure 3 The figure is a structural schematic view of the outer folding type display device in the folding state, that is, in the folding state, the flexible display panel 1 is located on the outer side of the supporting assembly 2, and in the folding state, the user can still observe the flexible display panel.

[0040] ​In these optional embodiments, in the folded state, the two magnetic parts 202 have the same magnetism, thus generating a driving force that moves the two magnetic parts 202 away from the bending area 101, so that the magnetic parts 202 can move from the bending area 101 to the non-bending area 102.

[0041] In some optional embodiments, the electromagnetic valve 3 is used to control the magnetism of the two magnetic parts 202 to be different when the folded state is changed to the bent state, so that the magnetic parts 202 can move from one side of the non-bending area 102 to one side of the bending area 101; the electromagnetic valve 3 is also used to control the magnetism of the two magnetic parts 202 to be the same when the bent state is changed to the folded state, so that the magnetic parts 202 can move from one side of the bending area 101 to one side of the non-bending area 102.

[0042] When the display device is closed and bent for a long time, there is a certain space under the screen of the bending area 101 in the flat state and there is a lack of supporting structure, so that collapse and indentation may occur. In these optional embodiments, the display panel further comprises an electromagnetic valve 3, when the display device is changed from the folded state to the flat state, the electromagnetic valve 3 can be controlled to control the magnetism of the magnetic parts 202 to be different, an attractive force that moves close to the bending area 101 is generated between the two magnetic parts 202, driving the two magnetic parts 202 to move close to each other, moving from one side of the non-bending area 102 to one side of the bending area 101, to support the screen of the bending area 101, thereby improving the collapse and indentation of the screen of the bending area 101 due to the lack of supporting structure under the screen of the bending area 101, thereby improving the flatness of the screen of the bending area 101.

[0043] When the display device is changed from the flat state to the folded state, the electromagnetic valve 3 can be controlled to control the magnetism of the magnetic parts 202 to be the same, an repulsive force that moves away from the bending area 101 is generated between the two magnetic parts 202, driving the two magnetic parts 202 to move away from each other, moving from one side of the bending area 101 to one side of the non-bending area 102, supporting the screen of the non-bending area 102 together with the fixed part 201.

[0044] Optionally, the electromagnetic valve 3 is located on the fixed part 201.

[0045] In some optional embodiments, the fixed part 201 is provided with a first accommodating cavity 2011, and in the bent state, the magnetic parts 202 are accommodated in the first accommodating cavity 2011.

[0046] In the optional embodiments, when the display device is in the bent state, the two magnetic parts 202 are of the same magnetic property, repulsion force is generated between the two magnetic parts 202, so as to drive the magnetic part 202 to move from one side of the bending area 101 to the first accommodating cavity 2011 of the fixed part 201, the first accommodating cavity 2011 can accommodate the magnetic part 202, and the magnetic part 202 and the fixed part 201 form the support assembly 2 to support the flexible display panel 1.

[0047] Optionally, in the unfolded state, when the two magnetic parts 202 are located in the first accommodating cavity 2011, the specific value of the distance between the two magnetic parts 202 is not limited here, and the user can set it according to the magnetic field strength of the two magnetic parts 202 or the size of the space reserved in the display device, as long as the force generated between the two magnetic parts 202 can drive the two magnetic parts 202 to reciprocate on one side of the bending area 101 and one side of the non-bending area 102.

[0048] In some optional embodiments, the display device further comprises a support plate 2012, the support plate 2012 and the flexible display panel 1 are arranged at intervals, and part of the support plate 2012 is extended from the bottom wall of the first accommodating cavity 2011 to the bending area 101 to support the magnetic part 202 located in the bending area 101.

[0049] In the optional embodiments, the support plate 2012 is used to support and limit the magnetic part 202 when the magnetic part 202 moves to the bending area 101, so that the two magnetic parts 202 are tightly attached to the screen body of the bending area 101, thereby improving the problem of collapse and indentation of the screen body in the bending area 101 without support.

[0050] In some optional embodiments, as shown in Figure 1 and Figure 4 The support plate 2012 comprises a connecting part 2013 and a guide part 2014, the connecting part 2013 is located on the bottom wall of the first accommodating cavity 2011, and in the same support plate 2012, the guide part 2014 is inclinedly arranged in a direction away from the flexible display panel 1.

[0051] In the optional embodiments, the support plate 2012 has the guide part 2014, and the guide part 2014 is inclinedly arranged in a direction away from the flexible display panel 1, which can improve the jamming generated in the process of moving the magnetic part 202 to the bending area 101, so that the magnetic part 202 can move to the bending area 101 to support it and reduce the wrinkles of the screen body in the bending area 101.

[0052] Optionally, the guide portion 2014 can be a guide rail, a guide groove, and the limiting portion can be a protrusion, a pulley or other components that can cooperate with the guide portion 2014, so that the magnetic portion 202 can move in the preset motion track without deviation when reciprocating between the bending area 101 and the non-bending area 102, thereby enabling the magnetic portion 202 to move to the side of the bending area 101 to support the screen body of the flexible display panel 1.

[0053] In some optional embodiments, the support assembly 2 further comprises a flexible support 203 connected to the inner wall of the two first accommodating cavities 2011, and the magnetic portion 202 is movably connected to the flexible support 203.

[0054] In these optional embodiments, the flexible support 203 is used for guiding and limiting the magnetic portion 202, so that the magnetic portion 202 does not deviate from the preset motion track when reciprocating between the bending area 101 and the non-bending area 102, and at the same time, since the flexible support 203 is flexible, it does not interfere with the motion track of the screen body of the flexible display panel 1 when the display device is in a bent state, so that the magnetic portion 202 can move along the preset motion track when reciprocating between the bending area 101 and the non-bending area 102, thereby enabling the magnetic portion 202 to accurately move to the side of the bending area 101 to support the flexible display panel 1.

[0055] Optionally, the fixed portion 201 has a through hole, and the flexible support 203 can pass through the through hole and be connected to the electromagnetic valve 3 located at the fixed portion 201, so as to control the magnetic properties of the two magnetic portions 202 to be the same or different through the flexible support 203, thereby providing a driving force for the reciprocating motion of the magnetic portion 203 between the side of the bending area 101 and the side of the non-bending area 102.

[0056] In some optional embodiments, the magnetic portion 202 has a first through hole 2022, and the magnetic portion 202 is sleeved on the flexible support 203 through the first through hole 2022 and is movable relative to the flexible support 203.

[0057] In these optional embodiments, the magnetic portion 202 has a first through hole 2022 through which the flexible support 203 passes, and the flexible support 203 passes through the first through hole 2022 and is connected to the inner wall of the first accommodating cavity 2011, forming a track for the reciprocating motion of the two magnetic portions 202 between the side of the bending area 101 and the side of the non-bending area 102, so that the magnetic portion 202 moves on the preset motion track without deviation.

[0058] In some optional embodiments, the magnetic part 202 further comprises a second accommodating cavity 2021, and the openings of the second accommodating cavities 2021 of the two magnetic parts 202 face each other; each second accommodating cavity 2021 is provided with a buffer 2023, and at least part of the buffer 2023 is exposed from the opening of the second accommodating cavity 2021.

[0059] In these optional embodiments, the second accommodating cavity 2021 is used to accommodate the buffer 2023, and when the two magnetic parts 202 move in the magnetic direction of the opposite side of the bending area 101, the two magnetic parts 202 will collide, which will easily damage the magnetic part 202. The buffer 2023 can play a role of shock absorption and buffering for the magnetic part 202, so as to improve the damage of the magnetic part 202 caused by the collision.

[0060] In some optional embodiments, as shown in Figure 1 and Figure 4 , the buffer 2023 comprises an elastic member 2024 and an abutting member 2025, the elastic member 2024 is fixed on the inner wall of the second accommodating cavity 2021 and is sleeved on the flexible support 203; the side of the elastic member 2024 away from the fixed part 201 has the abutting member 2025, the abutting member 2025 has a second through hole, the abutting member 2025 is sleeved on the flexible support 203 through the second through hole and is movable relative to the flexible support 203, and at least part of the abutting member 2025 extends out of the second accommodating cavity 2021 when the elastic member 2024 is in a natural state and has not collided.

[0061] Optionally, the elastic member 2024 can be a tensioning mechanism such as a spring, and any component that has elasticity or can play a role of shock absorption and buffering can be used.

[0062] Optionally, the abutting member 2025 can be a flexible gasket, a rubber pad, a rubber pad, a sponge pad, and any component that can play a role of shock absorption and buffering can be used.

[0063] In these optional embodiments, the abutting member 2025 of the buffer 2023 partially extends out of the second accommodating cavity 2021 in the natural state of the elastic member 2024, so that, as shown in Figure 2 , when the two magnetic parts 202 move in the magnetic direction of the opposite side of the bending area 101, due to the existence of the buffer 2023, the two abutting members 2025 will first collide, and then generate a force to extrude the elastic member 2024 to deform, thereby mitigating the impact generated by the collision of the two magnetic parts 202, playing a role of shock absorption and buffering for the magnetic part 202. The buffer 2023 is sleeved on the flexible support 203, and the flexible support 203 can complete the limiting and guiding of the magnetic part 202 and the buffer 2023, so the structure is simple and easy to implement.

[0064] The embodiment also provides a mobile terminal including the folding screen, the folding life of the folding screen in the mobile terminal is long, and the bending area 101 is not prone to functional problems such as wrinkle depression, and the user experience is good.

[0065] In these optional embodiments, the display device includes the flexible display panel 1 and the support assembly 2. The flexible display panel 1 can realize the transformation of the display device between the folded state and the flattened state through the bending area 101 thereof.

[0066] Optionally, the mobile terminal can be a mobile phone, a tablet computer, a smart folding watch or the like wearable display product.

[0067] The above is merely a specific implementation of the present application, and those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working processes of the above-described system, modules and units can refer to the corresponding processes in the foregoing method embodiments, which will not be described herein again.
