[0023] This disclosure also discloses a display device, which includes a flexible display module and the aforementioned sliding support device.

[0024] The embodiments disclosed herein have at least the following beneficial effects:

[0025] In the aforementioned sliding support device, the first support unit supports the non-display surface of the flexible display module. The first support member and the second support member of the first support unit are slidably connected in the sliding direction of the sliding support device, so that the first support unit can switch between a tightened state and an unfolded state, thereby allowing the flexible display module supported by the first support unit to switch between a tightened state and an unfolded state. A first hook rail provided on the first support member has a first hook rail opening in a first direction. The first hook head of the first hook body provided on the non-display surface of the flexible display module faces the first hook rail opening and can slide within the first hook rail. Thus, by sliding the first hook head within the first hook rail, a pulling force is applied to the flexible display module from the non-display surface, causing the non-display surface of the flexible display module to adhere to the first support member. On the one hand, by sliding the first hook head within the first hook track to apply tension to the flexible display module from its non-display surface, the display surface of the flexible display module can be prevented from being stressed, thus reducing the risk of damage or failure due to stress on the display surface. On the other hand, by sliding the first hook head within the first hook track, during the transition between the tightened and unfolded states of the first support unit, the second support member slides relative to the first support member in the sliding direction, while the flexible display module slides relative to the first support member in the sliding direction, keeping the non-display surface of the flexible display module in contact with the first support member, thus reducing defects such as bulging that occur during the rolling process of the flexible display module.

[0056] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0057] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this disclosure. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this disclosure provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0058] This disclosure is described below with reference to the accompanying drawings and specific embodiments:

[0059] In the field of display technology, flexible display modules 700 are characterized by their thinness, lightness, and high flexibility, thereby expanding the structural forms of terminal display devices. Terminal display devices have evolved towards various forms, including folding, single-roll, double-roll, and combinations of folding and single-roll designs. However, with market development, the existing forms of terminal display devices can no longer meet user needs.

[0060] For example, in the field of automotive displays, users and terminal manufacturers have increasingly demanded innovative forms, multi-screen displays, narrow bezels, high resolution, and large sizes. Traditional display terminals such as dashboards, central control screens, and in-vehicle entertainment systems are facing the challenge of continuous enrichment, upgrading, and enhanced integration. By providing users with more interactive experiences through full-display instruments, central control screens, head-up displays (HUDs), transparent A-pillars, sunroofs, and windows, automotive display products are gradually becoming more diversified. This trend is evident in everything from technical routes and spatial layouts to screen forms. Therefore, developing new forms of automotive display products is an important direction to meet user needs.

[0061] In related technologies, to prevent the flexible display module 700 from bulging relative to the support device during the sliding process, sliding display devices often install hooks on the side of the support device perpendicular to the sliding direction F1, with the hook head positioned on the display surface of the flexible display module 700. Force is applied from the display surface of the flexible display module 700 to press it against the support device, thus preventing bulging defects during sliding. However, because the hook head applies force from the display surface of the flexible display module 700, the display surface is prone to failure and damage due to stress, affecting the service life of the sliding display device. Furthermore, the hook can only be positioned on the side of the support device perpendicular to the sliding direction F1, meaning force can only be applied to the side area of ​​the flexible display module 700, leaving a risk of bulging defects in the central area of ​​the flexible display module 700.

[0062] This disclosure provides a sliding support device, as shown in Figures 1 to 27. The sliding support device includes a first support unit 100 and a first hook array 200. The first support unit 100 is used to support the non-display surface of a flexible display module 700. The first support unit 100 includes a first support member 110 and a second support member 120. The first support member 110 and the second support member 120 are slidably connected in a sliding direction F1 of the sliding support device, allowing the first support unit 100 to switch between a tightened state and an unfolded state. The first support member 110 extends along the sliding direction F1. The first hook track 111 has a first hook track opening in the first direction F2, which is perpendicular to the sliding direction F1 and parallel to the non-display surface. The first hook array 200 includes a plurality of first hook bodies 210, which are spaced apart along the sliding direction F1 on the non-display surface. Each first hook body 210 includes a first hook base 211 and a first hook head 212 disposed on the first hook base 211 and extending along the first direction F2. The first hook head 212 faces the first hook track opening and can slide within the first hook track 111.

[0063] The sliding support device disclosed in this embodiment is shown in Figures 1 to 27. The first support unit 100 is supported on the non-display surface of the flexible display module 700. The first support member 110 and the second support member 120 of the first support unit 100 are slidably connected in the sliding direction F1 of the sliding support device, so that the first support unit 100 can switch between a tightened state and an unfolded state, thereby allowing the flexible display module 700 supported by the first support unit 100 to switch between a tightened state and an unfolded state. As shown in Figures 7 to 16, the position of the first hook track is indicated by arrows. The first hook track 111, which is set on the first support member 110, has a first hook track opening in the first direction F2. As shown in Figures 17 to 19, the first hook head 212 of the first hook body 210, which is set on the non-display surface of the flexible display module 700, faces the first hook track opening and can slide within the first hook track 111. Thus, by sliding the first hook head 212 within the first hook track 111, a pulling force is applied to the flexible display module 700 from the non-display surface, so that the non-display surface of the flexible display module 700 is attached to the first support member 110. On the one hand, by sliding the first hook head 212 within the first hook track 111 to apply tension to the flexible display module 700 from its non-display surface, the display surface of the flexible display module 700 can be prevented from being stressed, thus reducing the risk of damage or failure caused by stress on the display surface of the flexible display module 700 to a certain extent. On the other hand, by sliding the first hook head 212 within the first hook track 111, during the transition between the tightened and unfolded states of the first support unit 100, the second support member 120 slides relative to the first support member 110 in the sliding direction F1, while the flexible display module 700 slides relative to the first support member 110 in the sliding direction F1, keeping the non-display surface of the flexible display module 700 in contact with the first support member 110, thus reducing defects such as bulging of the flexible display module 700 during the rolling process to a certain extent. Furthermore, since the first hook array 200 is disposed on the non-display surface of the flexible display module 700 and applies force to the flexible display module 700 from the non-display surface, the location of the first hook array 200 is not limited to the edge area of ​​the non-display surface of the flexible display module 700. It can also be disposed in the middle area of ​​the non-display surface of the flexible display module 700. Force can be applied to the flexible display module 700 from the middle area of ​​the non-display surface of the flexible display module 700, so that the middle area of ​​the non-display surface of the flexible display module 700 remains attached to the first support unit 100. This can reduce defects such as bulging of the flexible display module 700 in the middle area during the rolling process to a certain extent.

[0064] In some embodiments of this disclosure, when the first support unit 100 achieves the sliding roll of the flexible display module solely through the sliding 110 of the second support member 120 relative to the first support member, i.e., the sliding roll support device adopts a two-stage telescopic method, the first display end 710 of the flexible display module 700 can be connected to the second support member 120 by means of adhesive or the like. Optionally, the areas of the flexible display module 700 corresponding to the first display end 710 and the second support member 120 are all attached to the second support member 120. The first display end 710 of the flexible display module 700 can be connected to the second support member 120 by means of adhesive or the like. In the sliding direction F1, the second support member 120 is slidably disposed on the first support member 110, which can realize the sliding connection between the second support member 120 and the first support member 110, so that the second support member 120 and the first support member 110 can move towards each other and away from each other in the sliding direction F1, and the flexible display module 700 can be driven to move in the sliding direction F1 by the second support member 120. The opposing movement of the second support member 120 and the first support member 110 can shrink the first display area 730 formed by the first support unit 100 supporting the flexible display module 700, so that the flexible display module 700 in the display device switches to a tightened state; the opposing movement of the second support member 120 and the first support member 110 can enlarge the first display area 730 formed by the first support unit 100 supporting the flexible display module 700, so that the flexible display module 700 in the display device switches to an unfolded state.

[0065] In some embodiments of this disclosure, the second support member 120 and the first support member 110 can be in a sliding connection form with intersecting comb teeth in the sliding direction F1. Through the intersecting comb teeth sliding connection form of the second support member 120 and the first support member 110, the first support unit 100 can always provide support for the flexible display module 700 during the movement of the flexible display module 700, ensuring that the flexible display module 700 maintains flatness during the movement.

[0066] As an optional implementation, as shown in Figures 1 to 8, the sliding support device further includes a second support unit 400. The second support unit 400 is used to support the non-display surface of the flexible display module 700. The second support unit 400 is connected to the first support member 110 in the sliding direction F1 and the second support unit 400 and the first support member 110 are arranged at an angle, so that there is a display angle between the first display area 730 supported by the first support unit 100 and the second display area 740 supported by the second support unit 400.

[0067] In some embodiments of this disclosure, as shown in Figures 1 to 8, by setting the second support unit 400 at an angle to the first support member 110, a display angle can be formed between the first display area 730 supported by the first support unit 100 and the second display area 740 supported by the second support unit 400. In other words, the flexible display module 700 can have different display directions to meet the user's usage needs for different display directions. At the same time, in the sliding direction F1 of the flexible display module 700, the first support unit 100 can switch between a tightened state and an unfolded state, thereby adjusting the display ratio of the first display area 730 and the second display area 740, thus meeting the user's more diverse usage needs and achieving the purpose of multi-purpose use.

[0068] In some embodiments of this disclosure, as shown in Figures 1 to 6, the sliding support device and the display device are illustrated in their tightened and unfolded states from different perspectives. The overall shape of the display device resembles an "L" shape, with the flexible display module 700 sliding inside the "L" shape. This movement of the flexible display module 700 is considered as inward sliding. By sliding the flexible display module 700, the display device can achieve different display ratios, enabling its use in in-vehicle displays such as passenger-side entertainment and central control displays, thus broadening the structural and usage forms of the display device. Furthermore, based on the structural forms of the sliding support device and display device in the embodiments of this disclosure, the display device can be applied to other display needs.

[0069] In some embodiments of this disclosure, as shown in Figures 1 to 8, the first support member 110 is connected to the second support unit 400. The connection structure between the first support member 110 and the second support unit 400 ensures a stable relative structure between the first support unit 100 and the second support unit 400, thereby ensuring the relative position and display angle between the first display area 730 supported by the first support unit 100 and the second display area 740 supported by the second support unit 400.

[0070] In some embodiments of this disclosure, as shown in Figures 1 to 10, in the sliding direction F1, the sliding support device can preset the length ratio between the first support member 110, the second support member 120, and the second support unit 400, thereby preset the size of the first display area 730 and the second display area 740 in the tightened state, the size of the first display area 730 and the second display area 740 in the unfolded state, and the area ratio of the first display area 730 in the tightened and unfolded states. During the use of the sliding support device, the size of the first display area 730 formed by the first support unit 100 supporting the flexible display module 700 can be adjusted by adjusting the unfolded and tightened state of the first support unit 100, and the size of the second display area 740 formed by the second support unit 400 supporting the flexible display module 700 can be adjusted simultaneously, thereby adjusting the ratio of the first display area 730 to the second display area 740 of the flexible module.

[0071] In some embodiments of this disclosure, as shown in Figures 1 to 10, the sliding support device can adjust the structure and relative position of the first support unit 100 and the second support unit 400 to enable the flexible display module 700 to have a first display area 730 and a second display area 740 with different display directions, thereby meeting the user's usage requirements for different display directions. For example, it can be used as an entertainment display on the passenger side of a vehicle and a central control display in a vehicle, meeting the product usage requirements for different display directions. Simultaneously, in the sliding direction F1 of the flexible display module 700, the first support unit 100 can also switch between the tightened and unfolded states of the flexible display module 700, adjusting the size of the first display area 730 formed on the first support unit 100 and the second display area 740 supported on the second support unit 400, i.e., adjusting the ratio between the first display area 730 and the second display area 740, to meet more diverse usage requirements of the user. The user can adjust the size of the first display area 730 and the second display area 740 according to the intended use.

[0072] In some embodiments of this disclosure, optionally, when the sliding support device is used as both a vehicle-mounted passenger-side overhead entertainment display and a vehicle-mounted central control display, the ratio of the first display area 730 to the second display area 740 can be adjusted according to entertainment and / or central control requirements. For example, when there is an entertainment display requirement, the first display area 730 can be increased to provide a larger area to meet the needs of the passenger-side overhead entertainment display; when there is a central control display requirement, the first display area 730 can be reduced and the second display area 740 can be increased to provide a larger area to meet the needs of the central control display; when there are both entertainment and central control display requirements, the ratio of the area of ​​the first display area 730 to the second display area 740 can be maintained within a suitable range to simultaneously meet both entertainment and central control display requirements.

[0073] As an optional implementation, as shown in Figures 1 to 8, the included angle can be optionally displayed as [60°, 180°]; further optionally, the included angle can be displayed as [80°, 160°]; further optionally, the included angle can be displayed as [90°, 150°]; further optionally, the included angle can be displayed as [100°, 140°].

[0074] In some embodiments of this disclosure, as shown in Figures 1 to 8, by having a display angle between the first display area 730 supported by the first support unit 100 and the second display area 740 supported by the second support unit 400, the first display area 730 and the second display area 740 are not coplanar and are located in different planes, thus having different display angles to meet viewing needs from different angles. Optionally, by having a certain display angle between the first display area 730 supported by the first support unit 100 and the second display area 740 supported by the second support unit 400, the display angle requirements of the vehicle's passenger-side top entertainment and central control display can be better met. This allows the passenger to view the first display area 730, which serves as the top entertainment display, from a more comfortable angle while riding, without affecting the driver's view of the second display area 740, which serves as the central control display. Optionally, the display angle can be 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, 175°, etc.

[0075] As an optional implementation, as shown in Figures 1 to 27, the sliding support device includes two or more first hook rows 200 spaced apart in the first direction F2. The first support member 110 is provided with a first hook track 111 in the first direction F2 that matches the number and position of the first hook rows 200. The first hook rows 200 are evenly distributed in the first direction F2 and / or the first hook rows 200 are at least located in the edge area of ​​the non-display surface in the first direction F2.

[0076] In some embodiments of this disclosure, as shown in Figures 1 to 10 and Figures 18 to 19, the sliding support device includes two or more first hook rows 200 spaced apart in the first direction F2. At the same time, the first support member 110 is provided with a first hook track 111 in the first direction F2 that matches the number and position of the first hook rows 200. By sliding the first hook heads 212 of the two or more first hook rows 200 in the first hook track 111, two or more rows of tension can be formed on the non-display surface of the flexible display module 700 so that the non-display surface of the flexible display module 700 can be attached to the first support unit 100.

[0077] In some embodiments of this disclosure, as shown in Figures 1 to 10 and Figures 18 to 19, optionally, the first hook array 200 can be evenly distributed along the first direction F2, thereby forming a uniformly distributed tension along the first direction F2 on the non-display surface of the flexible display module 700, making the force on the non-display surface of the flexible display module 700 more balanced. Optionally, the first hook array 200 can be located at least in the edge region of the non-display surface along the first direction F2 to provide tension in the edge region of the non-display surface of the flexible display module 700, avoiding bulging defects in the edge region of the flexible display module 700.

[0078] In some embodiments of this disclosure, as shown in Figures 1 to 10 and Figures 18 to 19, the sliding support device includes four first hook rows 200 spaced apart in a first direction F2. Two of the first hook rows 200 are evenly distributed in the middle region of the non-display surface of the flexible display module 700, and two of the first hook rows 200 are distributed in the edge region of the non-display surface of the flexible display module 700. This not only makes the force on the non-display surface of the flexible display module 700 more balanced, but also provides tension in the middle and edge regions of the non-display surface of the flexible display module 700, thus avoiding bulging defects in the middle and / or edge regions of the flexible display module 700.

[0079] As an optional implementation, as shown in Figures 1 to 27, the first support unit 100 further includes a third support member 130, which is slidably connected to the second support member 120 in the sliding direction F1. The second support member 120 is provided with a second hook track 121 extending in the sliding direction F1, and the second hook track 121 has a second hook track opening in the first direction F2. The sliding support device further includes a second hook array 300, which includes a plurality of second hook bodies 310. The plurality of second hook bodies 310 are spaced apart in the non-display surface along the sliding direction F1. The second hook body 310 includes a second hook seat 311 and a second hook head 312 disposed on the second hook seat 311 and extending in the first direction F2. The second hook head 312 faces the second hook track opening and can slide within the second hook track 121.

[0080] In some embodiments of this disclosure, as shown in Figures 1 to 10, the first support unit 100 includes a third support member 130, which is slidably connected to the second support member 120 in the sliding direction F1. The first support member 110, the second support member 120, and the third support member 130 are slidably connected in the sliding direction F1 of the sliding support device, which enables the first support unit 100 to switch between a tightened state and an unfolded state. This allows the flexible display module 700 supported by the first support unit 100 to switch between a tightened state and an unfolded state, and further reduces the ratio of the tightened area to the unfolded area of ​​the first display area 730 formed by the flexible display module 700 supported by the first support unit 100.

[0081] In some embodiments of this disclosure, as shown in Figures 1 to 10, the first support unit 100 further includes a third support member 130, and the sliding support device further includes a second hook array 300. As shown in Figures 8 to 16, the arrows indicate the location of the second hook track 121. The second hook track 121, which is disposed on the second support member 120, has a second hook track opening in the first direction F2. The second hook head 312 of the second hook body 310 disposed on the non-display surface of the flexible display module 700 faces the second hook track opening and can slide within the second hook track 121. Thus, by sliding the second hook head 312 within the second hook track 121, a pulling force is applied from the non-display surface of the flexible display module 700 to the flexible display module 700, so that the non-display surface of the flexible display module 700 is attached to the second support member 120. By sliding the second hook head 312 within the second hook track 121 to apply tension to the flexible display module 700 from its non-display surface, the display surface of the flexible display module 700 can be prevented from being stressed, thus reducing the risk of damage or failure caused by stress on the display surface of the flexible display module 700 to a certain extent. During the transition between the tightened and unfolded states of the first support unit 100, the third support member 130 slides relative to the second support member 120 in the sliding direction F1, while the flexible display module 700 slides relative to the second support member 120 in the sliding direction F1, keeping the non-display surface of the flexible display module 700 in contact with the second support member 120, thus reducing defects such as bulging of the flexible display module 700 during the rolling process to a certain extent.

[0082] In some embodiments of this disclosure, the first hook array 200 and the second hook array 300 can be independently disposed on the non-display surface of the flexible display module 700. That is, the first hook array 200 and the second hook array 300 are distributed in a staggered manner on the non-display surface of the flexible display module 700.

[0083] In some embodiments of this disclosure, as shown in Figures 1 to 10, the first support unit 100 includes a third support member 130. The first display end 710 of the flexible display module 700 can be connected to the third support member 130 by means of adhesive or other methods. In the sliding direction F1, the second support member 120 is slidably disposed on the first support member 110, and the third support member 130 is slidably disposed on the second support member 120. This enables the second support member 120 to be slidably connected to the first support member 110 and the third support member 130 to be slidably connected to the second support member 120. This allows the second support member 120 and the first support member 110 to move towards each other and away from each other in the sliding direction F1, and the third support member 130 and the second support member to move towards each other and away from each other in the sliding direction F1. The flexible display module 700 is driven to move in the sliding direction F1 by the third support member 130. The relative movement of the third support member 130 and the second support member 120, and the relative movement of the second support member 120 and the first support member 110, can shrink the first display area 730 formed by the flexible display module 700 supported by the first support unit 100, while simultaneously enlarging the second display area 740 formed by the flexible display module 700 supported by the second support unit 400, thus allowing the flexible display module 700 in the display device to switch to a tightened state. The opposite movement of the third support member 130 and the second support member 120, and the opposite movement of the second support member 120 and the first support member 110, can enlarge the first display area 730 formed by the flexible display module 700 supported by the first support unit 100, while simultaneously shrinking the second display area 740 formed by the flexible display module 700 supported by the second support unit 400, thus allowing the flexible display module 700 in the display device to switch to an unfolded state.

[0084] In some embodiments of this disclosure, as shown in Figures 1 to 10, in the sliding direction F1, the length ratio between the first support member 110, the second support member 120, the third support member 130, and the second support unit 400 can be preset. This presets the sizes of the first display area 730 and the second display area 740 in the tightened state, the sizes of the first display area 730 and the second display area 740 in the unfolded state, and the area ratio of the first display area 730 in the tightened and unfolded states. During the use of the sliding support device, the size of the first display area 730 formed by the first support unit 100 supporting the flexible display module 700 can be adjusted by changing the unfolded and tightened state of the first support unit 100. Simultaneously, the size of the second display area 740 formed by the second support unit 400 supporting the flexible display module 700 can be adjusted, thereby adjusting the ratio of the first display area 730 to the second display area 740 in the tightened and unfolded states of the flexible module. In the first support unit 100, the three-segment first support member 110, second support member 120 and third support member 130 can make the size of the first display area 730 formed by the first support unit 100 have a larger adjustment range, thereby making the adjustment ratio range between the first display area 730 and the second display area 740 larger when the flexible module is in the tightened state and the unfolded state, providing more usage forms.

[0085] In other embodiments, the arrangement of the third support member 130 and the second support member 120 can be referenced to make the first support unit 100 include more relatively sliding support members, so that the first support unit 100 has a larger tightening ratio and a smaller display area in the tightened state.

[0086] In some embodiments of this disclosure, as shown in Figures 1 to 10, in the sliding direction F1, the third support member 130 and the second support member 120 can be in a sliding connection with intersecting comb teeth, and the second support member 120 and the first support member 110 can be in a sliding connection with intersecting comb teeth. Thus, during the movement of the flexible display module 700, the first support unit 100 can always provide support for the flexible display module 700, ensuring that the flexible display module 700 maintains flatness during the movement.

[0087] As an optional implementation, as shown in Figures 1 to 10, the first support unit 100 further includes a first guide rail assembly 140 and a second guide rail assembly 150. The first guide rail assembly 140 includes a first linear guide rail 141 and a first guide rail slider 142, which are respectively disposed on the second support member 120 and the first support member 110. The first linear guide rail 141 extends in the sliding direction F1, allowing the second support member 120 to be slidably connected to the first support member 110. The second guide rail assembly 150 includes a second linear guide rail 151 and a second guide rail slider 152, which are respectively disposed on the third support member 130 and the second support member 120. The second linear guide rail 151 extends in the sliding direction F1, allowing the third support member 130 to be slidably connected to the second support member 120.

[0088] In some embodiments of this disclosure, as shown in Figures 1 to 10, the first linear guide rail 141 extends in the sliding direction F1. By setting the first linear guide rail 141 on the first support member 110 or the second support member 120, and setting the first guide rail slider 142 correspondingly on the second support member 120 or the first support member 110, the second support member 120 can be slidably connected to the first support member 110 by sliding the first guide rail slider 142 on the first linear guide rail 141. In the sliding direction F1, the second support member 120 and the first support member 110 can move towards each other and away from each other. Similarly, as shown in Figures 1 to 10, the second linear guide 151 extends in the sliding direction F1. By setting the second linear guide 151 on the second support member 120 or the third support member 130, and setting the second guide slider 152 on the third support member 130 or the second support member 120 in correspondence with the second linear guide 151, the third support member 130 can slide on the second linear guide 151 through the sliding of the second guide slider 152, thereby realizing the sliding connection between the third support member 130 and the second support member 120. In the sliding direction F1, the third support member 130 and the second support member 120 can move towards each other and away from each other. Through the first guide assembly 140 and the second guide assembly 150, the movement accuracy of the third support member 130, the second support member 120, and the first support member 110 is ensured.

[0089] In some embodiments of this disclosure, as shown in Figures 1 to 10, the first linear guide rail 141 and the second linear guide rail 151 are disposed on the same side of the second support member 120, or the first linear guide rail 141 and the second linear guide rail 151 are respectively disposed on opposite sides of the second support member 120.

[0090] In some embodiments of this disclosure, the first guide rail assembly 140 and the second guide rail assembly 150 may be arranged in different forms in the first support unit 100 to achieve relative sliding between the second support member 120 and the first support member 110, and relative sliding between the third support member 130 and the second support member 120.

[0091] Optionally, the first guide rail assembly 140 and the second guide rail assembly 150 can be combined in a dual-segment single-rail configuration. The first linear guide rail 141 in the first guide rail assembly 140 and the second linear guide rail 151 in the second guide rail assembly 150 are independently mounted on the first support member 110, the second support member 120, or the third support member 130, respectively. The first guide rail slider 142 in the first guide rail assembly 140 and the second guide rail slider 152 in the second guide rail assembly 150 are then correspondingly mounted on the first support member 110, the second support member 120, or the third support member 130. Simultaneously, to avoid accumulated fitting errors in the dual-segment single-rail configuration, the installation accuracy of the first guide rail assembly 140 and the second guide rail assembly 150 must be ensured.

[0092] Optionally, the first support member 110 is provided with a first guide rail slider seat 114 for mounting the first guide rail slider 142; the third support member 130 is provided with a second guide rail slider seat for mounting the second guide rail slider 152. Simultaneously, the first linear guide rail 141 and the first guide rail slider 142 are correspondingly disposed on the second support member 120, and the second linear guide rail 151 and the second guide rail slider 152 are correspondingly disposed on the second support member 120 and located on the same side of the first support member 110. The first linear guide rail 141 and the second linear guide rail 151 are parallel, thereby allowing the second support member 120 to slide relative to the first support member 110 via the first guide rail assembly 140, and allowing the third support member 130 to slide relative to the second support member 120 via the second guide rail assembly 150.

[0093] Optionally, the second support member 120 is provided with a first guide rail slider seat 114 and a second guide rail slider seat side by side, for mounting the first guide rail slider 142 and the second guide rail slider 152, respectively. Simultaneously, a first linear guide rail 141 and a first guide rail slider 142 are correspondingly disposed on the first support member 110, and a second linear guide rail 151 and a second guide rail slider 152 are correspondingly disposed on the third support member 130, with the first linear guide rail 141 and the second linear guide rail 151 being parallel. This allows the second support member 120 to slide relative to the first support member 110 via the first guide rail assembly 140, and allows the third support member 130 to slide relative to the second support member 120 via the second guide rail assembly 150.

[0094] Optionally, the first linear guide rail 141 may have first limiting portions at its opposite ends to limit the relative movement range of the first guide rail slider 142 and the first linear guide rail 141. Similarly, the second linear guide rail 151 may have second limiting portions at its opposite ends to limit the relative movement range of the second guide rail slider 152 and the second linear guide rail 151.

[0095] In some embodiments of this disclosure, the second support member 120 has a guide rail mounting through hole, and the first linear guide rail 141 and the second linear guide rail 151 are disposed opposite to each other and are an integral structure, and the first linear guide rail 141 and the second linear guide rail 151 are mounted in the guide rail mounting through hole; or, the first guide rail slider 142 and the second guide rail slider 152 are disposed opposite to each other and are an integral structure, and the first guide rail slider 142 and the second guide rail slider 152 are mounted in the guide rail mounting through hole. By making the first linear guide rail 141 and the second linear guide rail 151 disposed opposite to each other and are an integral structure, or by making the first guide rail slider 142 and the second guide rail slider 152 disposed opposite to each other and are an integral structure, the first guide rail assembly 140 and the second guide rail assembly 150 can adopt a combination of single-segment linear guide rail or single-segment guide rail slider, which can improve the guide rail accuracy when the first guide rail assembly 140 and the second guide rail assembly 150 are used together, avoid the accumulation of assembly errors, and improve the movement accuracy of the first support unit 100. Compared to the dual-section single-rail combination, the first guide rail assembly 140 and the second guide rail assembly 150 adopt a combination of single-section linear guide rail or single-section guide rail slider, which can improve the guiding accuracy of the guide rail assembly and avoid the accumulation of assembly errors to a certain extent.

[0096] Optionally, the first guide rail assembly 140 and the second guide rail assembly 150 can be combined in a single-segment double-track configuration. The first linear guide rail 141 is mounted on the first support member 110 via screws or other connecting parts, and the second linear guide rail 151 is mounted on the third support member 130 via screws or other connecting parts. Meanwhile, a guide rail mounting through hole is provided on the second support member 120, and the integrally structured first guide rail slider 142 and second guide rail slider 152 are disposed in the guide rail mounting through hole and can be fixed to the second support member 120 via protruding guide rail slider fixing parts. After installation, the first guide rail slider 142 and the second guide rail slider 152 can be positioned on opposite sides of the second support member 120 to cooperate with the first linear guide rail 141 and the second linear guide rail 151 respectively. Optionally, the mutual limiting between the first linear guide rail 141 and the first guide rail slider 142 can be achieved by setting a limiting block on the first linear guide rail 141, and the mutual limiting between the second linear guide rail 151 and the second guide rail slider 152 can be achieved by setting a limiting block on the second linear guide rail 151.

[0097] Optionally, the first guide rail assembly 140 and the second guide rail assembly 150 can be combined in a single-segment double-slider configuration. The first support member 110 has a first guide rail slider seat 114 for mounting the first guide rail slider 142; the third support member 130 has a second guide rail slider seat for mounting the second guide rail slider 152. Simultaneously, a guide rail mounting through hole is provided on the second support member 120, and the integrally structured first linear guide rail 141 and second linear guide rail 151 are disposed in the guide rail mounting through hole. The guide rail slider and the second guide rail slider 152 can be mounted on the second support member 120 through protruding guide rail slider fixing parts, with the first guide rail slider 142 and the second guide rail slider 152 located on opposite sides of the second support member 120, respectively, to engage with the first linear guide rail 141 and the second linear guide rail 151. After installation, the first linear guide rail 141 and the second linear guide rail 151 can be located on opposite sides of the second support member 120, respectively, to engage with the first guide rail slider 142 and the second guide rail slider 152. Optionally, the mutual limiting between the first linear guide rail 141 and the first guide rail slider 142 can be achieved by setting a limiting block on the first linear guide rail 141, and the mutual limiting between the second linear guide rail 151 and the second guide rail slider 152 can be achieved by setting a limiting block on the second linear guide rail 151.

[0098] In some embodiments of this disclosure, the first support member 110 includes a first support end 112 and a first comb tooth engaging end 113 opposite to the first support end 112, the first support end 112 being used to connect with the second support unit 400; the second support member 120 includes a second comb tooth engaging end 122 and a second comb tooth mating end 123, the second comb tooth mating end 123 being engaged with the first comb tooth engaging end 113 in the sliding direction F1; the third support member 130 includes a third comb tooth mating end 132 and a third support end 131 opposite to the third comb tooth mating end 132, the third comb tooth mating end 132 being engaged with the second comb tooth engaging end 122 in the sliding direction F1, the third support end 131 being used to connect with the first display end 710 of the flexible display module 700. The first support end 112 is connected to the second support unit 400, thereby maintaining a stable relative structure between the first support unit 100 and the second support unit 400. This ensures the relative position and display angle between the first display area 730 supported by the first support unit 100 and the second display area 740 supported by the second support unit 400. In the sliding direction F1, the second comb tooth engagement end 123 of the second support member 120 can engage with the first comb tooth engagement end 113 of the first support member 110. That is, the second comb tooth engagement end 123 and the first comb tooth engagement end 113 are engaged with each other, thereby realizing the staggered connection of the comb teeth of the second support member 120 and the first support member 110. When the second support member 120 and the first support member 110 slide relative to each other, they always have a part that provides support for the flexible display module 700. Thus, during the unfolding and tightening process of the sliding support device, it always provides support for the flexible display module 700, ensuring that the flexible display module 700 remains flat. In the sliding direction F1, the third comb tooth engagement end 132 of the third support member 130 can engage with the second comb tooth engagement end 122 of the second support member 120. That is, the third comb tooth engagement end 132 and the second comb tooth engagement end 122 are engaged with each other, thereby realizing the staggered connection of the comb teeth of the third support member 130 and the second support member 120. When the third support member 130 and the second support member 120 slide relative to each other, they always have a part that provides support for the flexible display module 700. Thus, during the unfolding and tightening process of the sliding support device, it always provides support for the flexible display module 700, ensuring that the flexible display module 700 remains flat.

[0099] As an optional implementation, as shown in Figures 8 to 27, the arrows indicate the positions of the first hook track 111 and the second hook track 121. When the first support unit 100 is in the unfolded state, the first hook track 111 and the second hook track 121 have overlapping areas in the sliding direction F1; the openings of the first hook track and the second hook track are spaced apart and opposite to each other in the first direction F2; the first hook seat 211 and the second hook seat 311 are an integral structure, and the first hook head 212 and the second hook head 312 are arranged opposite to each other in the first direction F2.

[0100] In some embodiments of this disclosure, as shown in Figures 6 to 15, the first support member 110, the second support member 120, and the third support member 130 of the first support unit 100 can slide relative to each other. At the same time, the first display end 710 of the flexible display module 700 is connected to the third support member 130. When the first support unit 100 switches between a tightened state and an unfolded state, the flexible display module 700 slides relative to the first support member 110 and the second support member 120. Then, the first hook array 200 located on the non-display surface of the flexible display module 700 slides in the first hook track 111, and the second hook array 300 slides in the second hook track 121. There may be situations where the first hook body 210 enters and exits the first hook track 111, and the second hook body 310 enters and exits the second hook track 121.

[0101] As shown in Figures 17 and 18, to avoid the risk of interference and damage that may occur when the first hook body 210 enters the first hook track 111 and the second hook body 310 enters the second hook track 121, the first hook seat 211 and the second hook seat 311 can be integrated into one structure, and the first hook head 212 and the second hook head 312 can be set opposite to each other in the first direction F2. That is, the first hook body 210 and the second hook body 310 can have the same structure, and the first hook row 200 and the second hook row 300 can be integrated into one structure. At the same time, as shown in Figures 6 to 22, when the first support unit 100 is in the unfolded state, the first hook track 111 and the second hook track 121 have overlapping areas in the sliding direction F1, and the openings of the first hook track and the second hook track are spaced apart and opposite to each other in the first direction F2. That is, the first hook track 111 and the second hook track 121 are designed in a cross shape. When the first support unit 100 switches from a tightened state to an unfolded state, during the sliding process of the flexible display module 700 relative to the first support member 110 and the second support member 120, firstly, the first hook body 210 / second hook body 310 slides within the first hook track 111, that is, the first hook head 212 slides within the first hook track 111. Then, the first hook body 210 / second hook body 310 slides from the first hook track 111 to the second hook track 121. During the switching process from the first hook track 111 to the second hook track 121, the first hook body 210 and the second hook body 310 slide within the overlapping area of ​​the first hook track 111 and the second hook track 121 in the sliding direction F1, that is, the first hook head 212 slides in the first hook track 111 and the second hook head 312 slides in the second hook track 121; then the first hook body 210 and the second hook body 310 slide in the second hook track 121, that is, the second hook head 312 slides in the second hook track 121. During the switching process of the first hook body 210 / second hook body 310 from the first hook track 111 to the second hook track 121, it is ensured that the second hook head 312 of the first hook body 210 / second hook body 310 slides out of the first hook track 111 only after entering the second hook track 121. This allows the first hook body 210 / second hook body 310 to slide smoothly from the first hook track 111 to the second hook track 121, effectively avoiding the risk of interference and damage to the second hook track 121 when the first hook body 210 / second hook body 310 enters the second hook track 121. The process of switching the first support unit 100 from the unfolded state to the retracted state is similar to the process of switching the first support unit 100 from the retracted state to the unfolded state, and will not be described again here.

[0102] As an optional implementation, as shown in Figures 1 to 27, the sliding support device includes two or more first hook rows 200 spaced apart in the first direction F2, and a first support member 110 is provided with a first hook track 111 in the first direction F2 that matches the number and position of the first hook rows 200. The first hook rows 200 are evenly distributed in the first direction F2 and / or the first hook rows 200 are at least located in the edge region of the non-display surface in the first direction F2; and / or, the sliding support device includes two or more second hook rows 300 spaced apart in the first direction F2, and a second support member 120 is provided with a second hook track 121 in the first direction F2 that matches the number and position of the second hook rows 300. The second hook rows 300 are evenly distributed in the first direction F2 and / or the second hook rows 300 are at least located in the edge region of the non-display surface in the first direction F2.

[0103] In some embodiments of this disclosure, as shown in Figures 1 to 10 and Figures 18 to 19, the sliding support device includes two or more first hook rows 200 spaced apart in the first direction F2. At the same time, the first support member 110 is provided with a first hook track 111 in the first direction F2 that matches the number and position of the first hook rows 200. By sliding the first hook heads 212 of the two or more first hook rows 200 in the first hook track 111, two or more rows of tension can be formed on the non-display surface of the flexible display module 700 so that the non-display surface of the flexible display module 700 can be attached to the first support unit 100. Meanwhile, optionally, the sliding support device also includes two or more second hook rows 300 spaced apart in the first direction F2. At the same time, the second support member 120 is provided with a second hook track 121 in the first direction F2 that matches the number and position of the second hook rows 300. By sliding the second hook heads 312 of the two or more second hook rows 300 in the second hook track 121, two or more rows of tension can be formed on the non-display surface of the flexible display module 700 so that the non-display surface of the flexible display module 700 can be attached to the first support unit 100.

[0104] In some embodiments of this disclosure, as shown in Figures 1 to 10 and Figures 18 to 19, optionally, the first hook array 200 can be evenly distributed in the first direction F2, thereby forming a uniformly distributed tension on the non-display surface of the flexible display module 700 in the first direction F2, making the force on the non-display surface of the flexible display module 700 more balanced. Optionally, the first hook array 200 can be located at least in the edge region of the non-display surface in the first direction F2 to provide tension in the edge region of the non-display surface of the flexible display module 700, avoiding bulging defects in the edge region of the flexible display module 700. Simultaneously, optionally, the second hook array 300 can be evenly distributed in the first direction F2, thereby forming a uniformly distributed tension on the non-display surface of the flexible display module 700 in the first direction F2, making the force on the non-display surface of the flexible display module 700 more balanced. Optionally, the second hook array 300 may be located at least in the edge region of the non-display surface in the first direction F2 to provide tension in the edge region of the non-display surface of the flexible display module 700 and avoid bulging defects in the edge region of the flexible display module 700.

[0105] In some embodiments of this disclosure, as shown in Figures 8 to 10, optionally, the first support member 110 is provided with four first hook tracks 111, wherein two of the first hook tracks 111 are located in the edge region of the first support member 110, and two of the first hook tracks 111 are located in the middle region of the first support member 110; the openings of the first hook tracks 111 located in the edge region of the first support member 110 face the inside of the first support member 110 / first support unit 100 in the first direction F2; the openings of the first hook tracks 111 located in the middle region of the first support member 110 face the outside of the first support member 110 / first support unit 100 in the first direction F2. Meanwhile, the second support member 120 is provided with four second hook rails 121, two of which are located in the edge region of the second support member 120 and two of which are located in the middle region of the second support member 120; the second hook rail openings of the second hook rails 121 located in the edge region of the second support member 120 face the outside of the second support member 120 / first support unit 100 in the first direction F2, and the second hook rail openings of the second hook rails 121 located in the middle region of the second support member 120 face the outside of the second support member 120 / first support unit 100 in the first direction F2. When the first support unit 100 is in the tightened state, the opening of the first hook track is aligned with and flush with the opening of the second hook track. The first hook head 212 of the first hook body 210 / second hook body 310 slides in the first hook track 111, and at the same time, the second hook head 312 of the first hook body 210 / second hook body 310 slides in the second hook track 121. That is, the hook bodies on both sides of the first hook body 210 / second hook body 310 slide in the first hook track 111 and the second hook track 121 respectively.During the deployment of the first support unit 100, the first hook head 212 of the first hook body 210 / second hook body 310 slides within the first hook track 111 in the area corresponding to the first hook track 111, and the second hook head 312 of the first hook body 210 / second hook body 310 slides within the second hook track 121 in the area corresponding to the first hook track 111, ensuring that the first hook body 210 / second hook body 310 always retains one hook head sliding within the hook track, thus ensuring that the first hook body 210 / second hook body 310... The motion accuracy is 0; and the first hook track 111 and the second hook track 121 can still retain a certain degree of relative overlap, that is, in the switching area between the first hook track 111 and the second hook track 121, the opening of the first hook track and the opening of the second hook track remain relative and flush, so that the first hook body 210 / second hook body 310 can switch smoothly and stably within the first hook track 111 and the second hook track 121, avoiding the risk of collision when the hook heads of the first hook track 111 and the second hook track 121 are inserted into the hook track. During the tightening process of the first support unit 100, the first hook body 210 / second hook body 310 can always keep one side of the hook head sliding in the hook track, ensuring the movement accuracy of the first hook body 210 / second hook body 310; and the first hook body 210 / second hook body 310 can smoothly and steadily switch between the second hook track 121 and the first hook track 111, avoiding the risk of the hook heads of the first hook track 111 and the second hook track 121 colliding when they are inserted into the hook track.

[0106] As an optional implementation, as shown in Figures 1 to 27, the spacing between two or more first hook arrays 200 in the first direction F2 is 95.0 mm to 110.0 mm, the spacing between two or more second hook arrays 300 in the first direction F2 is 95.0 mm to 110.0 mm; and / or, the spacing between adjacent first hook arrays 200 and / or second hook arrays 300 in the first direction F2 is 95.0 mm to 110.0 mm; and / or, the ratio of the spacing between adjacent first hook arrays 200 and / or second hook arrays 300 in the first direction F2 to the size of the flexible display module 700 in the first direction F2 is (1:1) to (1:6).

[0107] In some embodiments of this disclosure, by making the spacing between two or more first hook arrays 200 in the first direction F2 95.0mm to 110.0mm, and the spacing between two or more second hook arrays 300 in the first direction F2 95.0mm to 110.0mm; and / or, by making the spacing between adjacent first hook arrays 200 and / or second hook arrays 300 in the first direction F2 95.0mm to 110.0mm, the first hook arrays 200 and / or second hook arrays 300 can have a better flattening and anti-bulging effect on the flexible display module 700, and can effectively avoid the bulging defects of the flexible display module 700. Optionally, the spacing between two or more first hook rows 200 in the first direction F2 is 98.0 mm to 103.0 mm, the spacing between two or more second hook rows 300 in the first direction F2 is 98.0 mm to 103.0 mm; and / or, the spacing between adjacent first hook rows 200 and / or second hook rows 300 in the first direction F2 is 98.0 mm to 103.0 mm. For example, the spacing between adjacent first hook rows 200 and / or second hook rows 300 in the first direction F2 can be 95.0mm, 96.0mm, 97.0mm, 98.0mm, 99.0mm, 100.0mm, 101.0mm, 102.0mm, 103.0mm, 104.0mm, 105.0mm, 106.0mm, 107.0mm, 108.0mm, 109.0mm, 110.0mm, etc.

[0108] In some embodiments of this disclosure, a simulation model is established in which the first hook array 200 and / or the second hook array 300 are symmetrically distributed on the non-display surface of the flexible display module 700 in the first direction F2. The rebound force of the flexible display module 700 is simulated and analyzed with a local load of 0.0003MPa as the boundary condition. As shown in Figure 24, when the interval between the first hook array 200 or the second hook array 300 located at the edge of the flexible display module 700 and the first hook array 200 or the second hook array 300 located in the middle of the flexible display module 700 is 95.0mm to 110.0mm, and when the interval between the first hook array 200 or the second hook array 300 located in the middle of the flexible display module 700 and the first hook array 200 or the second hook array 300 located in the middle of the flexible display module 700 is 95.0mm to 110.0mm, the bulge of the flexible display module 700 can be reduced. When the spacing between the first hook array 200 or the second hook array 300 located at the edge of the flexible display module 700 and the first hook array 200 or the second hook array 300 located in the middle of the flexible display module 700, and the spacing between the first hook array 200 or the second hook array 300 located in the middle of the flexible display module 700 and the first hook array 200 or the second hook array 300 located in the middle of the flexible display module 700, is 101.132mm, the bulge of the flexible display module 700 can be reduced, and the overall performance is better.

[0109] In some embodiments of this disclosure, the spacing between adjacent first hook arrays 200 and / or second hook arrays 300 in the first direction F2 can also be related to the size of the flexible display module 700 in the first direction F2. Therefore, the number and spacing between the first hook arrays 200 and / or second hook arrays 300 on the non-display surface of the flexible display module 700 can be set according to the size of the flexible display module 700 in the first direction F2. By making the spacing between adjacent first hook arrays 200 and / or second hook arrays 300 in the first direction F2 to the size of the flexible display module 700 in the first direction a ratio of (1:1) to (1:6), the first hook arrays 200 and / or second hook arrays 300 can provide a more balanced and effective force to the flexible display module 700, effectively reducing the bulge generated by the flexible display module 700. Optionally, the ratio of the spacing between adjacent first hook columns 200 and / or second hook columns 300 in the first direction F2 to the size of the flexible display module 700 in the first direction F2 is 1:2. For example, the first hook columns 200 are provided only on both sides of the flexible display module 700 in the first direction F2. Optionally, the ratio of the spacing between adjacent first hook columns 200 and / or second hook columns 300 in the first direction F2 to the size of the flexible display module 700 in the first direction F2 is 1:3. For example, four first hook columns 200 and / or second hook columns 300 are spaced apart on the flexible display module 700 in the first direction F2; first hook columns 200 and / or second hook columns 300 are provided on both sides of the flexible display module 700 in the first direction F2; and two columns of first hook columns 200 and / or second hook columns 300 are provided in the middle of the flexible display module 700 in the first direction F2. Optionally, the ratio of the spacing between adjacent first hook arrays 200 and / or second hook arrays 300 in the first direction F2 to the size ratio of the flexible display module 700 in the first direction F2 is 1:4, 1:5, 1:6, etc., which will not be illustrated here.

[0110] As an optional implementation, as shown in FIG25, the first hook head 212 and / or the second hook head 312 are provided with friction-reducing grooves extending along the sliding direction F1.

[0111] In some embodiments of this disclosure, as shown in FIG25, the first hook head 212 and / or the second hook head 312 are provided with friction-reducing grooves extending along the sliding direction F1, thereby reducing the contact area between the first hook head 212 and the first hook track 111, and the contact area between the second hook head 312 and the second hook track 121, thereby reducing the friction between the first hook head 212 and the first hook track 111, and the friction between the second hook head 312 and the second hook track 121, thereby reducing the movement resistance of the flexible display module 700 on the sliding support device and reducing the risk of damage to the flexible display module 700.

[0112] In some embodiments of this disclosure, as shown in FIG25, the first hook head 212 may be provided with a first friction-reducing groove 213, and the second hook head 312 may be provided with a second friction-reducing groove 313. The first friction-reducing groove 213 and the second friction-reducing groove 313 may be the same or different.

[0113] As an alternative implementation, as shown in Figures 1 to 27, the length of the first hook array 200 in the sliding direction F1 is at least greater than the total length of the first support member 110 and the second support member 120 in the sliding direction F1; the length of the second hook array 300 in the sliding direction F1 is at least greater than the length of the second support member 120 in the sliding direction F1.

[0114] In some embodiments of this disclosure, as shown in Figures 9 and 10, the moving length of the flexible display module 700 relative to the first support member 110 in the sliding direction F1 is the sum of the lengths of the first support member 110 and the second support member 120 in the sliding direction F1. By ensuring that the length of the first hook array 200 in the sliding direction F1 is at least greater than the total length of the first support member 110 and the second support member 120 in the sliding direction F1, it can be ensured that during the sliding process of the flexible display module 700 relative to the first support member 110, the first hook track 111 always has the first hook array 200 sliding within it, thus ensuring the constraint effect of the first hook track 111 and the first hook array 200 on the flexible display module 700.

[0115] In some embodiments of this disclosure, as shown in Figures 9 and 10, the flexible display module 700 moves relative to the second support member 120 in the sliding direction F1 by a length equal to the length of the second support member 120 in the sliding direction F1. By ensuring that the length of the second hook array 300 in the sliding direction F1 is at least greater than the length of the second support member 120 in the sliding direction F1, it can be ensured that during the sliding process of the flexible display module 700 relative to the second support member 120, the second hook track 121 always has the second hook array 300 sliding within it, thus ensuring the constraint effect of the second hook track 121 and the second hook array 300 on the flexible display module 700.

[0116] In some embodiments of this disclosure, as shown in Figures 9 and 10, when the first hook base 211 and the second hook base 311 are integral structures, and the first hook head 212 and the second hook head 312 are arranged opposite to each other in the first direction F2, that is, when the first hook column and the second hook column 300 are of the same structure, by making the length of the first hook column 200 / second hook column 300 in the sliding direction F1 at least greater than the total length of the first support member 110 and the second support member 120 in the sliding direction F1, it can be ensured that during the sliding process of the flexible display module 700 relative to the first support member 110 and the second support member 120, the first hook track 111, the second hook track 121 and the first hook column 200 / second hook column 300 achieve the constraint effect on the flexible display module 700.

[0117] As an optional implementation, as shown in Figures 1 to 13, the first support member 110 and / or the second support member 120 and / or the third support member 130 are provided with hollowed-out grooves 124.

[0118] In some embodiments of this disclosure, as shown in Figures 1 to 13, optionally, without affecting the connection between the first support member 110 and the second support unit 400, the mutual engagement with the second support member 120, and the supporting function for the flexible display module 700, a hollowed-out groove 124 can be formed on the first support member 110. This can reduce the friction between the first support member 110 and the second support member 120, and also reduce the weight of the first support member 110 itself. Optionally, the width of the comb teeth of the first support member 110 in the first direction F2 can be 15mm to 20mm, and the width of the hollowed-out groove 124 of the first support member 110 in the first direction F2 can be 15mm to 18mm.

[0119] In some embodiments of this disclosure, as shown in Figures 1 to 13, optionally, without affecting the mutual engagement between the second support member 120 and the first support member 110, the mutual engagement with the third support member 130, and the supporting function for the flexible display module 700, a hollowed-out groove 124 can be formed on the second support member 120 to reduce friction with the first support member 110 and / or the third support member 130, and also to reduce the weight of the second support member 120 itself. Optionally, the second support member 120 is provided with a comb-tooth groove for mutual engagement with the first support member 110 and the second support member 120. The width of the comb-tooth groove of the second support member 120 in the first direction F2 can be 5mm to 8mm to ensure that the second support member 120 has good comb-tooth strength and supporting performance for the flexible display module 700.

[0120] In some embodiments of this disclosure, as shown in Figures 1 to 13, optionally, without affecting the mutual engagement between the third support member 130 and the second support member 120 and the supporting function of the flexible display module 700, a hollowed-out groove 124 can be provided on the third support member 130, which can reduce the friction between it and the second support member 120 and also reduce the weight of the third support member 130 itself.

[0121] As an optional implementation, as shown in Figures 1 to 27, the second support unit 400 includes a fixed support member 410 and a sliding support member 420. The fixed support member 410 is connected to the first support member 110 in the sliding direction F1, and the fixed support member 410 and the sliding support member 420 are slidably connected in the sliding direction F1. The fixed support member 410 is provided with a third hook track 411 extending along the sliding direction F1. The third hook track 411 has a third hook track opening in the first direction F2. The third hook track 411 is connected to the first hook track 111, and the first hook head 212 can slide within the third hook track 411.

[0122] In some embodiments of this disclosure, as shown in Figures 6 to 11, the second support unit 400 includes a fixed support member 410 and a sliding support member 420. The fixed support member 410 is connected to the first support member 110 in the sliding direction F1, so that the first support unit 100 and the second support unit 400 maintain a stable relative structure, that is, ensure the relative position and display angle between the first display area 730 supported by the first support unit 100 and the second display area 740 supported by the second support unit 400.

[0123] In some embodiments of this disclosure, as shown in Figures 6 to 11, the fixed support 410 and the sliding support 420 are slidably connected in the sliding direction F1. That is, in the sliding direction F1, the sliding support 420 is slidably disposed on the fixed support 410, and the second display end 720 of the flexible display module 700 can be connected to the sliding support 420 by adhesive. During the unfolding and tightening process of the first support unit 100, when the first display end 710 of the flexible display module 700 slides in the sliding direction F1, the second display end 720 of the flexible display module 700 can slide synchronously in the sliding direction through the sliding support 420.

[0124] In some embodiments of this disclosure, as shown in Figures 1 to 11, the first support unit 100 includes a first support member 110, a second support member 120, and a third support member 130. The third support member 130 and the second support member 120 can be expanded and contracted relative to the first support member 110 in the sliding direction F1. The second support unit 400 includes a fixed support member 410 and a sliding support member 420. In the sliding direction F1, the sliding support member 420 is slidably disposed on the fixed support member 410, that is, the sliding support member 420 can be expanded and contracted relative to the fixed support member 410. The flexible display module includes a first display end 710 and a second display end 720 opposite to the first display end 710. The first display end 710 is fixed to a third support member 130, allowing the third support member 130 to move the first display end 710 in the sliding direction F1. The second display end 720 is fixed to a sliding support member 420, allowing the sliding support member 420 to move the second display end 720 in the sliding direction F1. During the unfolding and tensioning processes of the display device, the two ends of the flexible display module 700 are fixed by the third support member 130 and the sliding support member 420, thereby moving the flexible display module 700 in the sliding direction F1 to distribute the portion of the flexible display module 700 supported by the first support unit 100 and the portion supported by the second support unit 400. Optionally, the first display end 710 of the flexible display module 700 can be fixed to the third support member 130 by adhesive, and the second display end 720 of the flexible display module 700 can be fixed to the sliding support member 420 by adhesive.

[0125] In some embodiments of this disclosure, as shown in Figures 8 to 23, the arrows indicate the location of the third hook track 411. The fixed support member 410 is provided with a third hook track 411 extending along the sliding direction F1. The third hook track 411 has an opening in the first direction F2. The third hook track 411 is connected to the first hook track 111, and the first hook head 212 can slide within the third hook track 411. By allowing the first hook head 212 to slide within the third hook track 411, the flexible display module 700 can be constrained by the third hook track 411 and the first hook array 200 during the sliding process relative to the fixed support member 410, preventing defects such as bulging from occurring in the flexible display module 700. Simultaneously, since the third hook track 411 is connected to the first hook track 111, the first hook head 212 can smoothly switch between the third hook track 411 and the first hook track 111. The sliding process of the first hook column 200 in the third hook track 411 can be referred to as the movement process of the first hook column 200 in the first hook track 111. The setting method of the third hook track 411 on the fixed support 410 can be referred to as the setting method of the first hook track 111 on the first support 110, and will not be repeated here.

[0126] In some embodiments of this disclosure, as shown in Figures 11 to 12 and Figures 18 to 23, when the third hook track 411 is connected to the first hook track 111, the sliding of the first hook head 212 between the first hook track 111 and the second hook track 121 does not need to be switched. Therefore, the third hook track 411 can be arranged in a relatively opposite manner, that is, two third hook tracks 411 are arranged side by side with their openings facing each other, and one of the third hook tracks 411 is connected to the first hook track 111. When the first hook column 200 slides in the third hook track 411, the first hook head 212 / second hook head 312 of the first hook column 200, which are arranged relatively in the first direction F2, can slide on the two third hook tracks 411 respectively, which can make the sliding of the first hook column 200 in the third hook track 411 more stable.

[0127] In some embodiments of this disclosure, the third hook track 411 may not be connected to the first hook track 111, but may be configured such that the first hook track 111 and the second hook track 121 cooperate with each other. For example, the third hook track 411 and the first hook track 111 have overlapping areas in the sliding direction F1, and the openings of the third hook track and the first hook track are spaced apart and opposite to each other in the first direction F2. The sliding process of the first hook array 200 in the first hook track 111 and the third hook track 411 can be referred to as the sliding process of the first hook array 200 in the first hook track 111 and the second hook track 121, which will not be described again here.

[0128] In some embodiments of this disclosure, as shown in Figures 6 to 8, the second support unit 400 further includes a third guide rail assembly 430. The sliding support member 420 is slidably connected to the fixed support member 410 via the third guide rail assembly 430, thereby allowing the sliding support member 420 to move in the sliding direction F1. Optionally, the third guide rail assembly 430 includes a third linear guide rail 431 and a third guide rail slider 432. The two third linear guide rails 431 are disposed opposite to each other on the fixed support member 410 along the sliding direction F1, and are respectively located on opposite sides of the fixed support member 410 in the first direction F2. The two guide rail sliders are respectively disposed on the sliding support member 420, and are respectively located on opposite sides of the sliding support member 420 in the first direction F2. Through the two sets of third guide rail assemblies 430, the sliding support member 420 is constrained, allowing the sliding support member 420 to move in a directional manner along the sliding direction F1, thereby improving the movement accuracy of the sliding support member 420.

[0129] As an alternative implementation, as shown in Figures 1 to 27, the length of the first hook array 200 in the sliding direction F1 is at least greater than the total length of the first support member 110, the second support member 120, and the fixed support member 410 in the sliding direction F1.

[0130] In some embodiments of this disclosure, as shown in Figures 11 to 12 and Figures 18 to 23, the moving length of the flexible display module 700 relative to the first support unit 100 and the second support unit 400 in the sliding direction F1 is the sum of the lengths of the first support member 110, the second support member 120, and the fixed support member 410 in the sliding direction F1. By ensuring that the length of the first hook array 200 in the sliding direction F1 is at least greater than the total length of the first support member 110, the second support member 120, and the fixed support member 410 in the sliding direction F1, it can be ensured that during the sliding process of the flexible display module 700 relative to the sliding support device, the first hook array 200 can slide within the first hook track 111, the second hook track 121, and the third hook track 411, respectively, ensuring the constraint effect of the first hook array 200 and each hook track on the flexible display module 700.

[0131] As an optional implementation, as shown in Figures 1 to 27, the sliding support device further includes an arc-shaped retaining unit 500, which is connected between the fixed support member 410 and the first support member 110. The arc-shaped retaining unit 500 is used to support the non-display surface of the flexible display module 700. The arc-shaped retaining unit 500 includes an arc-shaped support member 510, which is an arc-shaped plate. The arc of the arc-shaped support member 510 is equal to the display angle.

[0132] In some embodiments of this disclosure, as shown in Figures 6 to 11, the arc-zone shaping unit 500 is disposed between the first support unit 100 and the second support unit 400, and the arc of the arc-zone support member 510 is equal to the display angle, so that the flexible display module 700 can always maintain a certain arc during the sliding process in the sliding support device, and avoid the flexible display module 700 from deforming or getting stuck at the display angle.

[0133] In some embodiments of this disclosure, as shown in Figures 6 to 11, the arc-shaped support member 510 may be provided with a hollowed-out groove 124, which can reduce the weight of the arc-shaped support member 510 itself. Optionally, the width of the hollowed-out groove 124 of the arc-shaped support member 510 in the first direction F2 can be 15mm to 18mm; the spacing of the hollowed-out grooves 124 of the arc-shaped support member 510 in the first direction F2 can be 15mm to 18mm.

[0134] As an optional implementation, as shown in Figures 1 to 27, the arc support member 510 is provided with a fourth hook track 511 extending along the sliding direction F1, and the fourth hook track 511 has a fourth hook track opening in the first direction F2; wherein, the fourth hook track 511 connects the first hook track 111 and the third hook track 411 and the first hook head 212 can slide within the fourth hook track 511.

[0135] In some embodiments of this disclosure, as shown in Figures 8 to 16, the arrows indicate the location of the fourth hook track 511. The arc support member 510 is provided with a fourth hook track 511 extending along the sliding direction F1. The fourth hook track 511 has an opening in the first direction F2. By allowing the first hook head 212 to slide within the fourth hook track 511, the flexible display module 700 can be constrained by the fourth hook track 511 and the first hook array 200 during the sliding process relative to the fixed support member 410, preventing defects such as bulging from occurring in the flexible display module 700. Simultaneously, since the fourth hook track 511 is connected to the first hook track 111 and the third hook track 411, the first hook head 212 can smoothly switch between the fourth hook track 511 and the first hook track 111 and the third hook track 411. The sliding process of the first hook column 200 in the fourth hook track 511 can be referred to as the movement process of the first hook column 200 in the first hook track 111. The setting method of the fourth hook track 511 on the arc support member 510 can be referred to as the setting method of the first hook track 111 on the first support member 110, and will not be repeated here.

[0136] As an alternative implementation, as shown in Figures 1 to 27, the length of the first hook array 200 in the sliding direction F1 is at least greater than the total length of the first support member 110, the second support member 120, and the arc area support member 510 in the sliding direction F1.

[0137] In some embodiments of this disclosure, as shown in Figures 20 to 23, by ensuring that the length of the first hook array 200 in the sliding direction F1 is at least greater than the total length of the first support member 110, the second support member 120, and the arc-shaped support member 510 in the sliding direction F1, when the first support unit 100 is in the tightened state, as shown in Figures 20 and 21, the first hook array 200 extends beyond the area of ​​the arc-shaped support member 510 in the sliding direction F1 and is located in the first hook track 111; when the first support unit 100 is in the unfolded state, as shown in Figures 22 and 23, the first hook array 200 extends beyond the area of ​​the arc-shaped support member 510 in the sliding direction F1 and is located in the third hook track 411, thereby effectively avoiding the risk of arc-shaped interference when the first hook array 200 enters or exits the fourth hook track 511.

[0138] As an alternative implementation, as shown in Figures 1 to 27, the length of the first hook array 200 in the sliding direction F1 is at least greater than the total length of the first support member 110, the second support member 120, the arc area support member 510, and the fixed support member 410 in the sliding direction F1.

[0139] In some embodiments of this disclosure, as shown in Figures 11-12 and 18-23, the flexible display module 700 moves relative to the first support unit 100, the second support unit 400, and the arc area support unit in the sliding direction F1 by a length equal to the sum of the lengths of the first support member 110, the second support member 120, the arc area support member 510, and the fixed support member 410 in the sliding direction F1. By ensuring that the length of the first hook array 200 in the sliding direction F1 is at least greater than the total length of the first support member 110, the second support member 120, the arc area support member 510, and the fixed support member 410 in the sliding direction F1, it can be ensured that during the sliding process of the flexible display module 700 relative to the sliding support device, the first hook array 200 can slide within the first hook track 111, the second hook track 121, the fourth hook track 511, and the third hook track 411, respectively, ensuring the constraint effect of the first hook array 200 and each hook track on the flexible display module 700.

[0140] As an optional implementation, as shown in Figures 1 to 27, the arc support member 510 and the first support member 110 are an integral structure, or the arc support member 510 and the fixed support member 410 are an integral structure, or the arc support member 510, the first support member 110 and the fixed support member 410 are an integral structure.

[0141] In some embodiments of this disclosure, as shown in Figures 6 to 11, the relative positions of the arc support 510, the first support 110, and the fixed support 410 are fixed. Therefore, the arc support 510 and the first support 110 can be integrated into one structure, or the arc support 510 and the fixed support 410 can be integrated into one structure, or the arc support 510, the first support 110, and the fixed support 410 can be integrated into one structure. This reduces the number of parts, improves the stability of the relative positions, and also reduces assembly steps and the accumulation of assembly errors.

[0142] As an optional implementation, as shown in Figures 1 to 27, the first hook array 200 is located at least in the edge region of the non-display surface in the first direction F2. The first hook track 111, the third hook track 411 and the fourth hook track 511 corresponding to the first hook array 200 in the edge region are integral side track members 160. The side track members 160 are disposed at the edges of the first support member 110, the arc area support member 510 and the fixed support member 410 in the first direction F2.

[0143] In some embodiments of this disclosure, as shown in Figures 6 to 11 and Figure 16, when the first hook array 200 is located in the edge region of the non-display surface in the first direction F2, it is necessary to respectively provide a first hook track 111, a third hook track 411, and a fourth hook track 511 in the edge regions of the first support member 110, the arc area support member 510, and the fixed support member 410 in the first direction F2. Furthermore, it is often necessary for the openings of the first hook track, the third hook track, and the fourth hook track 511 to be sufficiently open to face the interior of the sliding support device. By integrating the first hook track 111, the third hook track 411, and the fourth hook track 511 into a single side track component 160, and then placing the side track component 160 as a whole on the edge of the first support component 110, the arc area support component 510, and the fixed support component 410, it is possible to ensure that the first hook track 111, the third hook track 411, and the fourth hook track 511 are connected. This also improves the structural strength of the first hook track 111, the third hook track 411, and the fourth hook track 511, and avoids defects such as deformation.

[0144] As an optional implementation, the sliding support device further includes a tensioning transmission unit, which is connected to the third support member 130 and the sliding support member 420 respectively. The tensioning transmission unit is connected to both the third support member 130 and the sliding support member 420. Simultaneously, the third support member 130 is connected to the first display end 710 of the flexible display module 700, and the sliding support member 420 is connected to the second display end 720 of the flexible display module 700. This allows the tensioning transmission unit to be indirectly connected to both the first display end 710 and the second display end 720. The tensioning transmission unit enables tensioning and transmission between the third support member 130 and the sliding support member 420, allowing them to move synchronously. This provides an internal cyclic force for the synchronous movement of the third support member 130 and the sliding support member 420, and flattens the first display end 710 and the second display end 720 of the flexible display module 700, reducing creases.

[0145] As an optional implementation, as shown in Figures 1 to 8, the sliding support device further includes a drive unit 600, which is used to drive the sliding support 420 to slide relative to the fixed support 410.

[0146] In some embodiments of this disclosure, while the driving unit 600 drives the sliding support 420 to slide relative to the fixed support 410, the sliding support 420 is also connected to the third support 130 via a tensioning transmission unit. Thus, under the drive of the driving unit 600, the sliding support 420 and the third support 130 can move synchronously. Driven by the third support 130 and the sliding support 420, the flexible display module 700 can switch between a tightened state and an unfolded state, thereby realizing the driving force provided by the driving unit 600 to the sliding support device.

[0147] In some embodiments of this disclosure, as shown in Figures 1 to 8, the drive unit 600 includes a drive member 610 and a drive slider 630. The drive slider 630 is connected to a sliding support member 420, and a slider slot 421 may be provided on the sliding support member 420, within which the drive slider 630 may be disposed. The drive member 610 is disposed on the fixed support member 410 and may include a drive output shaft. The drive output shaft is connected to the drive slider 630 via a lead screw to drive the drive slider 630 to move in the sliding direction F1.

[0148] In some embodiments of this disclosure, as shown in Figures 1 to 8, the driving member 610 may be a drive motor. The drive output shaft of the driving member 610 is connected to the drive slider 630 through a lead screw. The lead screw can convert the rotational driving force of the drive output shaft into a linear driving force, thereby enabling the drive slider 630 to move in the sliding direction F1. At the same time, the drive slider 630 is connected to the sliding support member 420, thereby driving the sliding support member 420 to move in the sliding direction F1.

[0149] In some embodiments of this disclosure, as shown in Figures 1 to 8, the driving member 610 is provided with a driving member mounting seat 620. The driving member 610 is mounted on the fixed support member 410 through the driving member mounting seat 620, thereby fixing the driving member 610 relative to the fixed support member 410. When the driving member 610 converts the driving force of the driving member 610 into a linear driving force through the lead screw, the driving slider 630 can be driven to move in the sliding direction F1. Since the driving slider 630 is connected to the sliding support member 420, the driving slider 630 can drive the sliding support member 420 to move in the sliding direction F1. At the same time, the sliding support plate is connected to the third support member 130 through the tension transmission unit. The sliding support plate can drive the third support member 130 to move in the sliding direction F1, thereby realizing the driving of the sliding support device and enabling the flexible display module 700 supported by the sliding support device to switch between a tightened state and an unfolded state.

[0150] The sliding support device proposed in this embodiment can form an "L" shaped display device. Under the joint action of the first support unit 100, the second support unit 400, the arc area shaping unit 500, the tension transmission unit, and the drive unit 600, more than 700 display forms of the flexible display module are realized, which broadens the display forms of the display device and thus meets the richer needs of users.
