[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0029] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to non-detachable connections, detachable connections, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0032] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0033] In this application, "multiple" means two or more (including two).

[0034] With the continuous development of electronic information technology, various intelligent electronic devices are emerging one after another. Among them, the advent of foldable display devices has further improved the portability of electronic devices. Common foldable display devices include foldable screen phones and foldable tablets.

[0035] In related technologies, foldable display devices typically include a flexible screen and a housing supporting the flexible screen. The flexible screen can be bent freely, while the housing, as a rigid structure, is usually connected by hinges. At the connection points between adjacent housings, the flexible screen is difficult to effectively support. After the flexible screen has been closed and bent for a long time, it will have the inertia of bending when unfolded, resulting in a downward crease when the screen is flattened. For example... Figure 1 As shown in the image, the screen crease reduces the flatness of the flexible screen, thereby reducing its display effect. Furthermore, each time the flexible screen is opened, the door panels on both sides of the hinge exert an upward force on the screen, causing a slight bulge at the corresponding location, which may then present an "M"-shaped crease, further degrading the display effect of the flexible screen.

[0036] In view of the above-mentioned technical problems, this application proposes a display module having a first state and a second state. The display module includes a flexible display panel and a support device. The support device is disposed on one side of the flexible display panel and includes a fixing component, a supporting component, and a driving component. The fixing component includes at least two fixing frames that are rotatably connected to each other. The supporting component is disposed at the rotatable connection between two adjacent fixing frames and includes two supporting members. Each supporting member includes a first moving member and a second moving member that are linked to each other. The first moving member of one supporting member is retractably connected to one of the fixing frames, and the first moving member of the other supporting member is retractably connected to the other fixing frame. The driving component is disposed on the fixing frame and is used to drive the first moving member to move. In the first state, the driving component pushes the second moving member through the first moving member so that the second moving member abuts against the flexible display panel. In the second state, the driving component drives the second moving member through the first moving member so that the second moving member disengages from the flexible display panel.

[0037] According to the display module of this application embodiment, in a first state, the driving component of the support device drives the second moving member to abut against the flexible display panel. The second moving member provides support to the flexible display panel, alleviating the problem of creases caused by lack of support. In a second state, the driving component of the support device drives the second moving member to disengage from the flexible display panel, reducing the possibility of interference between the flexible display panel and the second moving member when bent, and improving the structural stability of the display module. Therefore, the display module of this application embodiment can effectively alleviate the problem of creases after bending and improve the display effect of the display module.

[0038] The following describes some embodiments of this application in further detail with reference to the accompanying drawings.

[0039] Please see Figure 2 , Figure 3 , Figure 8 and Figure 9The display module 100 has a first state and a second state. The display module 100 includes a flexible display panel 2 and a support device 1. The support device 1 is disposed on one side of the flexible display panel 2 and includes a fixing component 10, a support component 20, and a driving component 30. The fixing component 10 includes at least two fixing frames 11 that are rotatably connected relative to each other. The support component 20 is disposed at the rotatable connection between two adjacent fixing frames 11 and includes two support members 21. Each support member 21 includes a first moving part 211 and a second moving part 212 that are linked together. One of the support members 21... The first movable member 211 is retractably connected to one of the fixed frames 11, and the first movable member 211 of the other support member 21 is retractably connected to the other fixed frame 11; the drive assembly 30 is disposed on the fixed frame 11 and is used to drive the first movable member 211 to move; in the first state, the drive assembly 30 pushes the second movable member 212 through the first movable member 211 so that the second movable member 212 abuts against the flexible display panel 2; in the second state, the drive assembly 30 drives the second movable member 212 through the first movable member 211 so that the second movable member 212 disengages from the flexible display panel 2.

[0040] In this application, the flexible display panel 2 is an organic light-emitting diode (OLED), which may include a substrate, an anode, a hole injection layer, a hole transport layer, an electron blocking layer, a light-emitting layer, a hole blocking layer, an electron transport layer, an electron injection layer, a cathode, etc., or it may be a Micro LED or other types of display, which are not limited in this application.

[0041] The support device 1 is disposed on one side of the flexible display panel 2. It can be understood that the flexible display panel 2 can have a certain thickness, and the support device 1 is disposed on one side of the thickness direction X of the flexible display panel 2.

[0042] The support device 1 includes a fixing component 10, which includes at least two fixing frames 11 that are rotatably connected to each other. In other words, the fixing component 10 may include two or more fixing frames 11. When the fixing component 10 includes two fixing frames 11, the two fixing frames 11 can be rotatably connected to each other. When the fixing component 10 includes two or more fixing frames 11, the two or more fixing frames 11 can have various connection methods. For example, in some examples, the two or more fixing frames 11 can be arranged sequentially along a certain direction, with adjacent fixing frames 11 rotatably connected to each other. In other examples, multiple fixing frames 11 of the two or more fixing frames 11 can be arranged around at least one fixing frame 11, with the multiple fixing frames 11 surrounding the fixing frame 11 rotatably connected to the fixing frame 11 respectively. Of course, the two or more fixing frames 11 can also have other connection methods, and this application is not limited to these.

[0043] The support assembly 20 includes two support members 21, which correspond to two fixed frames 11 that are rotatably connected to each other. A first movable member 211 of each support member 21 is telescopically connected to the fixed frame 11. This telescopic connection can take various forms; for example, an elastic member can be used to connect the fixed frame 11 and the first movable member 211. During rotation, the fixed frame 11 can compress or release the elastic member, thereby driving the first movable member 211 to move, thus achieving a telescopic connection between the first movable member 211 and the fixed frame 11. Alternatively, a transmission mechanism can be used to connect the first movable member 211 and the fixed frame 11. The transmission mechanism can use the rotation of the fixed frame 11 as the driving force, thereby causing the first movable member 211 to telescopically move relative to the fixed frame 11. Exemplarily, in this embodiment, the support device 1 may include a drive assembly 30, which is disposed on the fixed frame 11. When the fixed frame 11 rotates relative to the support member 21, the fixed frame 11 can drive the drive assembly 30 to move, thereby driving the first movable member 211 to move, thus achieving a telescopic connection between the first movable member 211 and the fixed frame 11.

[0044] In the first state, the drive component 30 pushes the second moving component 212 through the first moving component 211 so that the second moving component 212 abuts against the flexible display panel 2. It can be understood that the first state can be considered as the flattened state of the display module 100. At this time, the second moving component 212 abuts against the flexible display panel 2, and the second moving component 212 can provide support and lift for the flexible display panel 2, which alleviates the problem of creases caused by the lack of effective support in the flexible display panel 2.

[0045] In the second state, the driving component 30 drives the second moving component 212 through the first moving component 211, so that the second moving component 212 is disengaged from the flexible display panel 2. It can be understood that the second state can be regarded as the bending state of the display module 100. At this time, the flexible display panel 2 will bulge towards the side closer to the support device 1 at its bending point. The disengagement of the second moving component 212 from the display panel can effectively reduce the possibility of structural interference between the flexible display panel 2 and the second moving component 212, which is beneficial to improving the structural stability of the display module 100.

[0046] It should be noted that the drive component 30 can drive the second moving component 212 to move through the first moving component 211. That is to say, there is a linkage between the first moving component 211 and the second moving component 212. The first moving component 211 and the second moving component 212 can be linked by a variety of transmission structures, such as mechanical transmission structure, hydraulic transmission structure or pneumatic transmission structure.

[0047] The display module 100 of this application embodiment not only effectively alleviates the problem of creases caused by lack of support in the flexible display panel 2 and improves the display effect of the display module 100, but also helps to improve the structural stability of the display module 100.

[0048] Please see Figure 3 and Figure 4 In some embodiments, the support member 21 further includes a receiving member 213, in which a first medium 214 is disposed, and a first moving member 211 and a second moving member 212 are respectively movably connected to the receiving member 213, and the first moving member 211 and the second moving member 212 are linked together through the first medium 214.

[0049] The receiving member 213 can be configured as a cavity structure with a certain volume, and the first medium 214 is located in the cavity of the receiving member 213 and can flow in the cavity.

[0050] The first moving member 211 and the second moving member 212 are respectively movably connected to the receiving member 213. It is understood that the first moving member 211 and the second moving member 212 are not only connected to the receiving member 213, but also capable of relative movement relative to the receiving member 213. There are various ways to achieve this movable connection. For example, a guide structure and a track can be used, where the guide structure can move along the track, thereby achieving the movable connection between the first moving member 211, the second moving member 212, and the receiving member 213. Alternatively, an end-face contact method can be used, where the end faces of the first moving member 211 and the second moving member 212 respectively abut against the receiving member 213 and can slide relative to the receiving member 213, thereby achieving the movable connection between the first moving member 211, the second moving member 212, and the receiving member 213. This application does not limit the specific connection method.

[0051] The first moving part 211 and the second moving part 212 are linked together through the first medium 214. It can be understood that at least a portion of the first medium 214 is located between the first moving part 211 and the second moving part 212, and the first moving part 211 and the second moving part 212 are linked together through the flow of the first medium 214.

[0052] The first medium 214 can be in various states, including gaseous and liquid states. For example, in this embodiment, the first medium 214 can be a liquid. Liquids have low compressibility and high pressure resistance, which is beneficial to enhancing the motion stability and motion accuracy of the first moving part 211 and the second moving part 212.

[0053] In this embodiment, the first moving member 211 and the second moving member 212 are linked together through the first medium 214, which simplifies the transmission between the first moving member 211 and the second moving member 212, thereby simplifying the structure of the support member 21 and reducing the volume of the display module 100.

[0054] Please continue reading. Figure 3 and Figure 4 In some embodiments, the receiving member 213 includes a first receiving cavity 213a and a second receiving cavity 213b, a first medium 214 is disposed in the second receiving cavity 213b, and a first moving member 211 separates the first receiving cavity 213a and the second receiving cavity 213b.

[0055] The receiving member 213 includes a first receiving cavity 213a and a second receiving cavity 213b. A first moving member 211 separates the first receiving cavity 213a and the second receiving cavity 213b. That is, the first receiving cavity 213a and the second receiving cavity 213b can be two mutually independent and isolated cavities. The volume of the first receiving cavity 213a and the second receiving cavity 213b can change with the movement of the first moving member 211. When the volume of the first receiving cavity 213a increases, the volume of the second receiving cavity 213b decreases accordingly. When the volume of the first receiving cavity 213a decreases, the volume of the second receiving cavity 213b increases accordingly.

[0056] In this embodiment, the first medium 214 is located in the second receiving cavity 213b, and the first moving member 211 separates the first receiving cavity 213a and the second receiving cavity 213b. This can increase the contact area between the first moving member 211 and the first medium 214, which is beneficial to optimizing the force transmission effect between the first moving member 211 and the first medium 214, thereby enhancing the transmission effect of the first moving member 211 and the second moving member 212.

[0057] The second movable member 212 is disposed in the second receiving cavity 213b, and the second movable member 212 and the first medium 214 can have various configuration forms.

[0058] For example, in some examples, such as Figure 3 As shown, the first medium 214 is partially located on one side of the second moving member 212 and partially fills the space between the second moving member 212 and the receiving member 213. This reduces the difficulty of connecting the second moving member 212 and the receiving member 213, which helps to improve the connection reliability of the second moving member 212 and the receiving member 213, thereby improving the reliability of the display module 100.

[0059] For example, in other examples, such as Figure 6 As shown, the first medium 214 is located on one side of the second moving member 212. In these examples, the first medium 214 can be located between the first moving member 211 and the second moving member 212, which can increase the contact area between the second moving member 212 and the first medium 214, thereby optimizing the force transmission effect between the second moving member 212 and the first medium 214, and helping to enhance the transmission effect of the first moving member 211 and the second moving member 212.

[0060] Please see Figures 3 to 5 In some embodiments, the second movable member 212 includes a first part 212a and a second part 212b. The first part 212a is movably connected to the receiving member 213. The second part 212b is connected to the first part 212a and disposed outside the receiving member 213. The second part 212b is used to abut against the flexible display panel 2.

[0061] The first part 212a and the second part 212b are connected in various ways. They can be detachable, such as threaded or snap-fit ​​connections, or non-detachable, such as welding or bonding. Alternatively, they can be connected as a single piece, meaning the second moving part 212 is a one-piece molded structure. For example, in this embodiment, the second moving part 212 can be a one-piece molded structure.

[0062] The second part 212b is used to abut against the flexible display panel 2. Compared with the first part 212a, the second part 212b can have a larger surface area, which can increase the contact area with the flexible display panel 2 and enhance the support effect on the flexible display panel 2. Furthermore, the connection between the first part 212a and the receiving member 213 can reduce the connection difficulty between the second moving member 212 and the receiving member 213, and reduce the structural volume of the supporting member 21 to a certain extent.

[0063] Please continue reading. Figures 3 to 5In some embodiments, the support member 21 further includes a sealing member 215 that seals the first movable member 211 and the receiving member 213, and seals the second movable member 212 and the receiving member 213.

[0064] The sealing component 215 can have various structural forms, such as a sealing ring or a sealing gasket. The sealing component 215 can be made of an elastic material, which can deform under compression to achieve a sealing effect. Common materials for the sealing component 215 include rubber, graphite, or polytetrafluoroethylene (PTFE).

[0065] Figure 4 A schematic diagram showing the sealing component 215 sealing the first moving member 211 and the receiving member 213. Figure 5 A schematic diagram showing the sealing component 215 sealing the second movable member 212 and the receiving member 213. Figure 4 and Figure 5 In this process, the sealing component 215 can be deformed under the squeezing action of the first moving component 211 and the receiving component 213, and the second moving component 212 and the receiving component 213. The deformed sealing component 215 has a tendency to recover its deformation, thereby sealing and filling the gap between the first moving component 211 and the receiving component 213, and the second moving component 212 and the receiving component 213, so as to achieve a sealing effect.

[0066] The embodiment of this application provides a sealing component 215, which can enhance the sealing between the first moving part 211 and the receiving part 213, and enhance the sealing between the second moving part 212 and the receiving part 213, reducing the possibility of leakage of the first medium 214, thereby improving the transmission reliability between the first moving part 211 and the second moving part 212, improving the working reliability of the support member 21, and thus improving the safety and reliability of the display module 100.

[0067] Please see Figure 6 In some embodiments, the drive assembly may include a drive rod 31, the end of the drive rod 31 near the first moving member 211 being configured as an arc-shaped end, the arc-shaped end being tangent to the first moving member 211.

[0068] The arc-shaped end of the drive rod 31 is tangent to the first moving member 211, and there can be various configuration relationships between the arc-shaped end and the first moving member 211.

[0069] For example, in this embodiment, the arc-shaped end can contact the first moving member 211. When the arc-shaped end approaches the first moving member 211 and applies a force to it, the first moving member 211 compresses the first medium 214 under the push of the arc-shaped end, thereby forcing the first medium 214 to push the second moving member 212 to rise. When the arc-shaped end moves away from the first moving member 211, the contact force between the arc-shaped end and the first moving member 211 gradually decreases until the contact force between the arc-shaped end and the first moving member 211 is less than the pressure given by the first medium 214. At this time, the force exerted on the second moving member 212 by the first medium 214 decreases, and the second moving member 212 descends.

[0070] Of course, in other examples, the arc-shaped end can also be connected to the first moving part 211. For example, a track for the movement of the arc-shaped end can be set on the first moving part 211. When the arc-shaped end moves, it can push or pull the first moving part 211 to move, thereby indirectly realizing the linkage of the second moving part 212 through the first medium 214.

[0071] It should be noted that, in this embodiment, the horizontal plane where the second moving member 212 is located can be higher than the horizontal plane where the first moving member 211 is located, so that the first medium 214 can fall back under its own gravity, thereby simplifying the transmission connection between the first medium 214 and the second moving member 212, and thus simplifying the structural form of the display module 100.

[0072] In this embodiment, the arc-shaped end is tangent to the first moving member 211, which reduces the possibility of structural jamming when the drive rod 31 and the first moving member 211 transmit force, improves the smoothness of their movement, and thus enhances the working stability and reliability of the display module 100. Furthermore, the arc-shaped end of the drive rod 31 also reduces the friction between the drive rod 31 and the first moving member 211, thereby reducing frictional losses during power transmission.

[0073] Furthermore, such as Figure 7 As shown, the drive assembly may further include a rolling member 33, which is connected to the end of the drive rod 31 near the first moving member 211 and is rotatable relative to the end of the drive rod 31. The rolling member 33 is used to be tangent to the first moving member 211.

[0074] The rolling component 33 is rotatably connected to the end of the drive rod 31. The rolling component 33 can have various structural forms, such as a cylindrical structure or a spherical structure. The rolling component 33 is tangential to the first moving component 211. When the rolling component 33 abuts against the first moving component 211, it can roll along the surface of the first moving component 211 under force. This further reduces the frictional force between the drive rod 31 and the first moving component 211, reducing frictional loss. Furthermore, it can further improve the smoothness and reliability of force transmission, which is beneficial to improving the working stability and reliability of the display module 100.

[0075] Furthermore, combined Figure 8 and Figure 9 The drive assembly 30 also includes a support 32, which is disposed on the fixed frame 11, and the drive rod 31 is connected to the support 32.

[0076] By providing a support 32 in this embodiment, the connection between the drive rod 31 and the fixed frame 11 can be facilitated, which helps to reduce the difficulty of connecting the drive assembly 30 and the support member 21.

[0077] Please continue reading. Figure 8 and Figure 9 In any of the above embodiments of the display module 100, the support device 1 may further include a connecting component 40, which is disposed between two adjacent fixed frames 11 and rotatably connected to the two fixed frames 11 respectively, and the support component 20 is located between the connecting component 40 and the flexible display panel 2.

[0078] The connecting component 40 is rotatably connected to two fixed frames 11. The connecting component 40 and the fixed frames 11 can be connected by a hinge. The hinge connection has high reliability and good stability, which is beneficial to improving the structural stability and operational reliability of the display module 100.

[0079] The support component 20 is located between the connecting component 40 and the flexible display panel 2. The support component 20 can be installed on the connecting component 40. The support component 20 and the connecting component 40 can adopt various connection methods, which can be non-detachable or detachable. This application does not limit this.

[0080] Please see Figure 10 This application also proposes a display device that includes the display module 100 of any of the above embodiments. The display device of this application can be a mobile phone, a computer, or any other electronic device or electronic device with display function.

[0081] The display device in this application embodiment may include a folded state and a flattened state. In the folded state, the flexible display panel 2 is bent and the display module 100 is in a second state; in the flattened state, the flexible display panel 2 is flattened and the display module 100 is in a first state.

[0082] The state switching process of the display module 100 in this embodiment of the application will be further explained below:

[0083] Please see Figure 2 , Figure 3 , Figure 8 , Figure 9 When the display module 100 changes from the first state to the second state, the angle between the fixing frame 11 and the support member 21 gradually increases. At this time, the driving component 30 gradually moves away from the first moving member 211 under the drive of the fixing frame 11. The force exerted by the driving component 30 on the first moving member 211 gradually decreases. When the force exerted by the driving component 30 on the first moving member 211 is less than the force exerted by the first medium 214 on the first moving member 211, the first moving member 211 moves in the direction away from the first medium 214. The first medium 214 flows in the direction close to the first moving member 211 under its own gravity. As a result, the force exerted by the first medium 214 on the second moving member 212 decreases. The second moving member 212 begins to descend under its own gravity, thereby gradually detaching from the flexible display panel 2. During this process, the flexible display panel 2 may bend at the bend and tilt toward the second moving member 212. Those skilled in the art can reasonably set the displacement of the second moving member 212 in specific implementations to avoid interference between the second moving member 212 and the tilted part of the flexible display panel 2 as much as possible.

[0084] Conversely, when the display module 100 changes from the second state to the first state, the angle between the fixing frame 11 and the support member 21 gradually decreases. At this time, the driving component 30 gradually approaches the first moving member 211 under the drive of the fixing frame 11. When the force exerted by the driving component 30 on the first moving member 211 is greater than the force exerted by the first medium 214 on the first moving member 211, the first moving member 211 pushes the first medium 214 to flow, thereby the first medium 214 exerts a force on the second moving member 212, forcing the second moving member 212 to rise. Then the second moving member 212 gradually approaches the flexible display panel 2, and when the flexible display panel 2 is flattened, the second moving member 212 can abut against the flexible display panel 2.

[0085] The embodiments described above are not exhaustive, nor do they limit the invention to specific embodiments. Clearly, many modifications and variations can be made based on the above description. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of this application, enabling those skilled in the art to effectively utilize this application and its modifications. It should be understood that the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and all such modifications or substitutions should be included within the scope of protection of this application.
