[0013] Based on the above bending structure, optionally, the first main component includes a first surface close to the bent part, and the first surface does not contact the bent part when the bent part is bent and unfolded.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions in the embodiments of this invention will be clearly and completely described below in conjunction with the embodiments of this invention. Obviously, the described embodiments are only some embodiments of this invention, not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] Application Overview

[0039] In recent years, flexible display devices that can be folded 360 degrees have emerged in the industry. 360-degree folding tests the bending capacity limit of flexible screens, and this form has become a research focus in the display industry. However, the module materials of foldable displays are currently mainly based on flexible film and adhesive materials. After undergoing multiple cyclic inward and outward bends, the module materials will be subjected to cyclic tension and compression, making the flexible screen highly susceptible to bending failure.

[0040] To address the aforementioned risk of bending failure, such as Figure 1-3 Currently, the industry commonly designs differentiated teardrop-shaped inward folds and U-shaped outward folds to enhance the bending capability for 360-degree bending. That is, different bending shapes are used during inward and outward folds, so that the bending stress of the flexible screen is concentrated on different areas of the flexible screen during these processes, thereby reducing the periodic tension and compression on the module material in the same area. However, in practice, when switching between inward and outward folds, the entire or part of the film layer in the bending area is prone to reverse arching (reverse folding). For example... Figure 4 As shown, Figure 4 In the diagram, the dashed line represents the ideal shape of the flexible screen's bending area during the current bending process, while the actual shape shows an inverted arching phenomenon.

[0041] To address the aforementioned problems, this invention provides an improved bending structure. By incorporating a flattening device to apply force to the bending area of ​​structures such as flexible screens, the bending area is better restored to a flattened state, improving the stress distribution in the bending area and thus avoiding the risk of bending failure. The following examples and embodiments provide non-limiting descriptions of specific implementation schemes.

[0042] Exemplary bending structure

[0043] Reference Figures 5-9 , Figure 5 This is a top view of a bending structure provided in one embodiment of the present invention. Figure 6 for Figure 5 The diagram shows a cross-sectional view of the bent structure along the AA′ plane. Figure 7 This is a cross-sectional view of a bending structure provided in one embodiment of the present invention. Figure 8 This is a cross-sectional view of a bending structure with a bent component provided in another embodiment of the present invention. Figure 9 This is a cross-sectional schematic diagram of a bending structure with a bent component provided in another embodiment of the present invention. For example... Figure 5-9 As shown, the bending structure of this embodiment includes: two support plates 1 and a flattening device 3; wherein,

[0044] There is a gap region P between the two support plates 1, and a guide rail 10 is provided inside the end of the support plate 1 facing the gap region P;

[0045] The flattening device 3 is disposed in the interval region P. The flattening device 3 includes a first main body component 31 and a second main body component 32 connected to each other. The first main body component 31 includes a magnetic component. The first main body component 31 is used to provide force to the bending area of ​​the bent part 4 through the magnetic component to flatten the bending area of ​​the bent part 4. The second main body component 32 can move telescopically along the guide rail 10 and is partially retracted into the support plate 1 or extended from the support plate 1 to drive the first main body component 31 to move in the interval region P in a direction close to or away from the support plate 1.

[0046] Among them, such as Figure 7-9 As shown, the bent component 4 is attached to the bending structure. The bent component 4 includes a bending area 41 and non-bending areas 42 located on both sides of the bending area 41. Two support plates 1 are used to support the non-bending areas 42 of the bent component 4, and the interval region P corresponds to the bending area 41 of the bent component 4. The bent component 4 can be a flexible screen, etc. For example, the bending structure of this embodiment can be used in a folding screen, or it can be used for bending tests during the manufacturing process of a flexible screen. In this embodiment and subsequent embodiments of the present invention, the bent component 4 is described using a flexible screen as an example. In addition, in practice, the bent component 4, such as a flexible screen, can be attached to the support plate 1 with an adhesive material, etc. This is a conventional technique, so it is not illustrated in the embodiments of the present invention.

[0047] Reference Figure 7 As shown, when the flexible screen is subjected to inward bending force, a certain degree of concave deformation will occur at the center of the bending area 41 in the flattened state. In this case, the magnetic component of the first main body component 31 of the flattening device 3 can provide an upward force (in the direction of the dotted line with arrows in the figure) to the bending area of ​​the flexible screen, that is, a magnetic repulsion force, thereby improving the concave deformation at the center of the bending area, so that the bending area can better return to the planar state before bending, as shown in the figure. Figure 9 As shown, when the flexible screen is folded outward, the phenomenon of reverse arching can be effectively avoided.

[0048] In order to apply the magnetic force of the magnetic component of the first main component 31 to the bending area of ​​the flexible screen, a magnetic material with magnetism can be placed in a specific structure of the bending area of ​​the flexible screen. For example, stainless steel material that has been specifically magnetized can be used as the support film layer of the flexible screen, or permanent magnets or magnetic structures that have been specifically magnetized can be placed in some film layers of the bending area of ​​the flexible screen. In this way, by reasonably setting the magnetic field direction of the magnetic component of the first main component 31, a repulsive force can be generated between the magnetic component of the first main component 31 and the magnetic material of the flexible screen, thereby helping the bending area of ​​the flexible screen to flatten.

[0049] Reference Figure 8 As shown, when a flexible screen is subjected to force due to outward bending, a certain degree of convex deformation will occur at the center of the bending area in the flattened state. In this case, the first main component 31 of the flattening device 3 can provide a downward force (in the direction of the dotted line with arrows in the figure) to the bending area of ​​the flexible screen through the magnetic component, that is, magnetic attraction, thereby improving the convex deformation at the center of the bending area, so that the bending area can better return to the planar state before bending, as shown in the figure. Figure 9 As shown, when the flexible screen is folded inward, the phenomenon of reverse arching can be effectively avoided.

[0050] In order to apply the magnetic force of the magnetic component of the first main component 31 to the bending area of ​​the flexible screen, a magnetic material with magnetism can be set in a specific structure of the bending area of ​​the flexible screen. For example, stainless steel material that has been specifically magnetized can be used as the support film layer of the flexible screen, or permanent magnets or magnetic structures that have been specifically magnetized can be set in some film layers of the bending area of ​​the flexible screen. In this way, by reasonably setting the magnetic field direction of the magnetic component of the first main component 31, an attractive force can be generated between the magnetic component of the first main component 31 and the magnetic material of the flexible screen, thereby helping the bending area of ​​the flexible screen to flatten.

[0051] It should be noted that in this embodiment, there are two support plates 1. However, this is only an example. In other embodiments, there may be three or more support plates 1, which is suitable for scenarios where flexible screens and other bent parts 4 are bent in multiple segments. In such scenarios, a flattening device 3 can be set in the interval area between any two adjacent support plates 1 to assist in flattening the bending area of ​​the bent part 4.

[0052] In some embodiments, the magnetic component is an electromagnetic component, and the magnetic direction of the electromagnetic component is adjustable.

[0053] Specifically, the magnetic component may include a magnetic core and a coil wound around the magnetic core. When the coil is energized, it generates a magnetic field, thereby providing magnetic force. Furthermore, depending on the direction of the current flowing through the coil, the magnetic poles of the magnetic field generated by the coil are different, thus enabling adjustment of the direction of the magnetic field and the direction of the magnetic force (magnetic attraction or magnetic repulsion).

[0054] Thus, in some embodiments, the first main component 31 can provide a first force when the bent part 4 is flattened from the first bent shape by a magnetic component, and a second force when the bent part 4 is flattened from the second bent shape; wherein the bending directions of the first and second bent shapes are opposite, and the directions of the first and second forces are opposite. For example, the first bent shape can be a teardrop-shaped inward fold, and the second bent shape can be a U-shaped outward fold, in which case the first force is a magnetic repulsion force, and the second force is a magnetic attraction force.

[0055] Furthermore, considering that components such as the first main component 31 can affect the normal bending process of the flexible screen, a guide rail 10 is provided inside the support plate 1 near the interval region P. The second main component 32 is designed to slide along the guide rail 10, meaning it can partially retract into and extend from the support plate 1, thereby causing the first main component 31 to move within the interval region towards or away from the support plate 1. With this configuration, during bending, the second main component 32 can slowly retract into the support plate 1 along the guide rail 10, causing the first main component 31 to move towards the support plate 1, thus providing the space required for bending the flexible screen. After bending and flattening, the second main component 32 can extend outwards from the support plate 1 along the guide rail 10, causing the first main component 31 to move away from the support plate 1. This allows the first main component 31 to better apply force to the center of the bending area of ​​the flexible screen, thereby reducing the magnetic force required from the magnetic components of the first main component 31.

[0056] In some embodiments, the flattening device 3 may further include a driving component 33, which may include a servo motor. The extension and retraction of the second main body component 32 can be achieved by switching the servo motor in forward and reverse directions. For example, the second main body component 32 extends when the servo motor rotates forward and retracts when the servo motor rotates in reverse. Further, in some embodiments, the second main body component 32 may include spur gears. The driving component 33 can drive the second main body component 32 to extend and retract along the guide rail 10 through a gear 33a that meshes with the spur gears of the second main body component 32. For example, when the driving component 33 uses a servo motor, the output shaft of the servo motor can directly or indirectly drive the gear 33a to rotate, and then drive the second main body component 32 to extend and retract along the guide rail 10 through the meshing structure of the gear 33a.

[0057] In addition, in practice, when switching the bending direction, the direction of the current flowing through the magnetic component of the first main body component 31 can be changed simultaneously to switch the bending direction and the magnetic direction of the first main body component 31 synchronously.

[0058] Furthermore, such as Figure 5 As shown, the drive component 33 can be disposed inside the support plate 1, thereby reducing the space occupied by the flattening device 3 and protecting the drive component 33 from damage.

[0059] It should be noted that, as Figure 5 As shown, the two support plates 1 are rotatably connected by the rotating component 2, and the relative rotatable angle between the two support plates 1 is 0 to 360°. That is, the bending structure in the above embodiments can be used in scenarios where flexible screens and other bent components are bent 360 degrees. However, it is understood that in some embodiments, the relative rotatable angle between the two support plates 1 can also be 0 to 180°, meaning the bending structure can also be used for 180-degree bending scenarios. In this case, the magnetic direction of the magnetic component of the first main body component 31 does not need to be changed, therefore the magnetic component can be a permanent magnet.

[0060] Reference Figure 10 and Figure 11 , Figure 10 This is a top view of a bent structure provided in another embodiment of the present invention. Figure 11 for Figure 10 The diagram shows a cross-sectional view of the bent structure along the BB′ plane. Figure 10 and Figure 11 As shown, in some embodiments, the support plate 1 has a protrusion 1a at one end near the interval region. An auxiliary guide rail 11, extending in the same direction as the guide rail 10, is provided within the protrusion 1a. The second main body component 32 has an extension 32a extending perpendicular to the telescopic direction, and the extension 32a can move along the auxiliary guide rail 11. With this configuration, the extension 32a of the second main body component 32 can provide auxiliary support for the entire second main body component 32 as it moves along the auxiliary guide rail 11, making the operation of the flattening device 3 more stable.

[0061] It should be noted that in the above figures of the present invention, the examples are all based on the premise that both support plates 1 are provided with flattening devices 3, that is, the number of flattening devices 3 is two. However, it is understood that in some embodiments, flattening devices 3 may be provided in only one of the support plates 1. In this way, it can also help the bent part 4 to be flattened better to a certain extent, and can simplify the bending structure.

[0062] In addition, refer to Figure 12 , Figure 12 for Figure 10This is a schematic diagram of another cross-sectional structure of the bent structure along the BB′ plane. (See diagram below.) Figure 12 As shown, in some embodiments, when there are two flattening devices 3, and each of the two flattening devices 3 corresponds to one of the two support plates 1, the first main body component 31 of the two flattening devices 3 can be a splicable structure. Thus, when the second main body component 32 is in the extended state, the first main body components 31 can be very close to each other, in a spliced ​​state, thereby better applying the magnetic force to the center of the bending area of ​​the bent part 4, and further reducing the magnitude of the magnetic force required by the first main body component 31. Furthermore, since the required magnetic force is relatively small in practice, i.e., the magnetic field of the magnetic component is relatively weak, the repulsive force between the two first main body components 31 is very small. Therefore, the driving component 33 can provide sufficient driving force to bring the two first main body components 31 very close to each other.

[0063] In addition, if Figure 6-12 As shown, in some embodiments, the first main body component 31 includes a first surface 31a adjacent to the bent component 4. Figure 6-12 In the first main component 31, the first surface 31a is the upper surface, and the first surface 31a does not contact the bent component 4 when the bent component 4 is bent and flattened. Taking the bent component 4 as a flexible screen as an example, refer to... Figures 13-15 As shown, when the flexible screen is in a teardrop-shaped inward fold, a U-shaped outward fold, or a flattened state, the first surface 31a of the first main body component 31 does not contact the bent component 4. This prevents the flexible screen from being scratched or abraded by the first surface 31a of the first main body component 31.

[0064] Furthermore, such as Figure 6-15 As shown, the first surface 31a is a convex arc. Thus, even when the first surface 31a comes into contact with the bent component 4 during use, the contact area is relatively small due to its convex shape, better preventing scratches or abrasions to the flexible screen. Furthermore, since the bending deformation of the bent component 4 is more pronounced in the center of the bending area (i.e., the bending degree is greater in the center and less on the sides), the convex shape of the first surface 31a provides a relatively larger force, thus better helping to flatten the bending area of ​​the bent component 4, resulting in a better improvement effect.

[0067] Because the display device in this embodiment has the above-mentioned bending structure, it can better restore the display device to its original planar state after bending, thereby reducing the risk of failure after multiple bends and extending the service life of the display device.
