Detailed Implementation

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] In related technologies, the inward folding hinge solution for foldable products mainly uses a physical axis and a virtual center to achieve teardrop-shaped panel corner control and slippage compensation. Specifically, the hinge teardrop-shaped panel control screen and the hinge center support plate together form a triangular space, and the screen's shape within the hinge is fixed by adhesive layers, resulting in a final teardrop shape.

[0045] However, due to the limitations of the hinge center support plate, this foldable product only allows the screen to be bonded to a localized area between the hinge teardrop plate and the hinge center support plate. Therefore, in actual use, the area where the screen is bonded to the hinge center support plate is prone to warping after multiple folds, resulting in severe creases.

[0046] In view of this, this application proposes a pivot support structure and display device. A first support plate is provided, with its orthographic projection on the flexible display panel located within the bending area. The first support plate has multiple chain plates, with any two adjacent chain plates being rotatably connected. An adhesive layer is provided on the side of the first support plate facing the flexible display panel, and the first support plate is connected to the bending area of ​​the flexible display panel through the adhesive layer. Thus, when the flexible display panel is folded or bent, the multiple chain plates of the first support plate can rotate accordingly with the bending area of ​​the flexible display panel, thereby increasing the contact area between the first support plate and the bending area of ​​the flexible display panel. This helps to reduce warping deformation in the bending area, and consequently reduces creases in the flexible display panel.

[0047] Reference Figure 1 and Figure 2 As shown, this application discloses a pivot support structure for supporting a flexible display panel (not shown in the figure). The flexible display panel includes a flat area and at least one bent area. The pivot support structure includes a first support plate 10 and second support plates 20 located on both sides of the first support plate 10.

[0048] Specifically, the flat area of ​​a flexible display panel refers to the area whose cross-section remains straight after the flexible display panel is folded or bent; while the area whose cross-section is curved after the flexible display panel is folded or bent is the bending area. Furthermore, in a typical flexible display panel, both sides of a bending area are usually flat areas. Through this structure, the flexible display panel can be folded or bent once with the bending area as the bending point.

[0049] Reference Figure 1 and Figure 2As shown, the first support plate 10 is the structure in the pivot support structure that supports the bending area of ​​the flexible display panel. Therefore, the orthographic projection of the first support plate 10 on the flexible display panel is located within the bending area. That is, in the direction from the first support plate 10 to the flexible display panel, the position of the first support plate 10 is opposite to the position of the bending area of ​​the flexible display panel. The first support plate 10 has a certain length, and the length direction of the first support plate 10 is perpendicular to the folding or bending direction of the flexible display panel. Simultaneously, connecting sections 60 are provided at both ends of the first support plate 10 along its length direction, and the connecting sections 60 can be connected to the pivot mechanism.

[0050] Furthermore, referring to Figure 3 As shown, the first support plate 10 includes multiple chain plates 101, and any two adjacent chain plates 101 are rotatably connected. Specifically, each chain plate 101 can rotate relative to one or two adjacent chain plates 101. When each chain plate 101 has rotated relative to another chain plate, the entire first support plate 10 can become arc-shaped. Then, by connecting the first support plate 10 to the bending area of ​​the flexible display panel, the first support plate 10 can deform along with the bending of the bending area, thereby ensuring that the first support plate 10 and the bending area always remain in close contact.

[0051] The number of chain plates 101 can be greater than or equal to 3 and less than or equal to 9. Exemplarily, the number of chain plates 101 can be 3, 4, 5, 6, etc., and those skilled in the art can set it according to actual needs. In a preferred embodiment, the number of chain plates 101 is preferably an odd number, such as 3, 5, or 7. This is more conducive to the fabrication of the first support plate 10 and allows the first support plate 10 to bend better with the mating bending area. Meanwhile, in this embodiment, the shape and size of each chain plate 101 are approximately the same. However, the width of each chain plate 101 can actually be different. For example, when the number of chain plates 101 is odd, the width of the chain plate 101 located in the middle can be set to the smallest, and the width of the chain plates 101 from the middle to the outside can be increased sequentially, as long as the entire first support plate 10 is a symmetrical structure.

[0052] Furthermore, referring to Figure 1 and Figure 2As shown, the second support plate 20 is a structure in the pivot support structure that supports the flat area of ​​the flexible display panel. Therefore, the orthographic projection of the two second support plates 20 on the flexible display panel is located within the flat area. That is, in the direction from the first support plate 10 to the flexible display panel, the position of the second support plate 20 is opposite to the position of the flat area of ​​the flexible display panel. Since the two sides of the bending area of ​​a typical flexible display panel are flat areas, the two second support plates 20 are respectively opposite to the two flat areas, and the second support plates 20 are connected to the flat areas of the flexible display panel. During the folding process of the flexible display panel, the second support plates 20 always remain in contact with the flat areas.

[0053] Meanwhile, among the multiple chain plates 101, the chain plate 101 closest to the second support plate 20 is rotatably connected to the second support plate 20. The chain plate 101 closest to the second support plate 20 refers to the chain plate 101 adjacent to the second support plate 20. By utilizing the rotatable connection between the chain plate 101 and the second support plate 20, a rotatable connection between the first support plate 10 and the second support plate 20 can be achieved. Therefore, the second support plate 20 will not affect the bending of the first support plate 10, and the connection position between the first support plate 10 and the second support plate 20 can better maintain a close fit with the flexible display panel, further reducing the possibility of warping of the flexible display panel.

[0054] Furthermore, referring to Figure 4 As shown, an adhesive layer is provided on the side of the first support plate 10 facing the flexible display panel, and the first support plate 10 is connected to the bending area of ​​the flexible display panel through the adhesive layer.

[0055] Specifically, the adhesive layer includes a plurality of adhesive strips 301 spaced apart on the first support plate 10, with the adhesive strips 301 extending along the length of the first support plate 10. The adhesive strips 301 can be made of a material with strong adhesion; therefore, the plurality of adhesive strips 301 can connect and fix the first support plate 10 and the flexible display panel, resulting in a tighter connection between the first support plate 10 and the flexible display panel. This allows the first support plate 10 to better conform to the bending area of ​​the flexible display panel and bend along with the bending area. Hot melt adhesive can be used as the adhesive strips 301.

[0056] In practical applications, each chain plate 101 can be individually equipped with one or more adhesive strips 301, the specific number of which can be determined based on the spacing between the adhesive strips 301. In this embodiment, the distance between two adjacent adhesive strips 301 can be greater than 0 mm and less than or equal to 1 mm. For example, the distance between two adjacent adhesive strips 301 can be 0.1 mm, 0.2 mm, 0.3 mm, 0.5 mm, 1 mm, etc., and those skilled in the art can select according to actual needs.

[0057] Furthermore, in the embodiments of this application, the flexible display panel may include an OLED (Organic Light-Emitting Diode) display panel, a QLED (Quantum Dot Light-Emitting Diodes) display panel, and a Micro-LED (Micro Light-Emitting Diode Display) display panel. Different types of flexible display panels may include different light-emitting structures. For example, when the flexible display panel is an OLED display panel, it may include a substrate and a light-emitting layer disposed on the substrate. The light-emitting layer may further include an anode, an electron transport layer, a light-emitting material layer, a hole injection layer, a hole transport layer, and a cathode, etc.

[0058] The rotating support structure provided in this application embodiment can support a flexible display panel using a first support plate 10 and second support plates 20 located on both sides of the first support plate 10. The first support plate 10 corresponds to the bending area of ​​the flexible display panel, and the second support plate 20 corresponds to the flat area of ​​the flexible display panel. The first support plate 10 is composed of multiple chain plates 101, and any two adjacent chain plates 101 are rotatably connected, so that the first support plate 10 can be bent in conjunction with the bending area. This allows the bending area of ​​the flexible display panel to remain in contact with the first support plate 10 during the folding process, thereby limiting the warping deformation of the flexible display panel and reducing creases caused by repeated folding of the flexible display panel.

[0059] In one alternative implementation, refer to Figure 3 and Figure 5 As shown, this application embodiment also provides a pivot support structure, in which the chain plate 101 includes a main body 1011 and connecting parts 1012 located at both ends of the main body 1011.

[0060] Specifically, the main body 1011 is the main part of the chain plate 101, and the connecting parts 1012 are provided at both ends of the main body 1011 in the length direction as connecting parts of the chain plate 101 to other chain plates 101.

[0061] Furthermore, referring to Figure 5As shown, the main body 1011 and the connecting part 1012 are offset. That is, along the length of the main body 1011, the center line of the main body 1011 and the center line of the connecting part 1012 are not on the same straight line; for example, the straight line containing the center line of the connecting part 1012 may be located near the edge of the main body 1011. In this way, at least one embedding region A is formed between the main body 1011 and the connecting part 1012.

[0062] In two adjacent chain plates 101, the connecting portion 1012 of one chain plate 101 is embedded in the embedding region A of the other chain plate 101, and the two adjacent chain plates 101 are rotatably connected by the connecting portion 1012. Specifically, in this embodiment, the two adjacent chain plates 101 can be rotatably connected by a connecting pin 40. The connecting pin 40 passes through the connecting portion 1012 of one of the two adjacent chain plates 101, and also passes through the main body portion 1011 of the other chain plate 101, and is located within the embedding region A. In this way, the two adjacent chain plates 101 can rotate about the connecting pin 40 as a rotation axis.

[0063] At the same time, refer to Figure 6 As shown, when the number of chain plates 101 is odd, the direction of the offset between the connecting part 1012 and the main body part 1011 of each chain plate 101 is not consistent in the middle chain plate and the chain plates on both sides.

[0064] Specifically, the plurality of chain plates 101 include a first chain plate 102 located in the middle and at least one second chain plate 103 located on both sides of the first chain plate 102. The connecting portions of the second chain plates 103 are offset from the main body of the second chain plate 103 relative to the position of the first chain plate 102. For example, the connecting portion of the second chain plate 103a located to the left of the first chain plate 102 is offset to the right from its main body, while the connecting portion of the second chain plate 103b located to the right is offset to the left from its main body. This creates an embedding region A between the main body of the second chain plate 103 and the connecting portion of the second chain plate 103.

[0065] Reference Figure 6As shown, when the number of chain plates 101 is odd, the first chain plate 102 needs to form two embedding areas A so that the connecting portions of the second chain plates 103 on both sides can be embedded respectively. Specifically, the connecting portion 1012 of the first chain plate 102 located in the middle is on the same straight line as the center line of the main body portion 1011 of the first chain plate 102. Therefore, for the first chain plate 102, the staggered arrangement of the connecting portion 1012 and the main body portion 1011 means that the connecting portion 1012 of the first chain plate 102 is staggered relative to the two side edges of the main body portion 1011, so that two embedding areas A can be formed.

[0066] When the number of chain plates 101 is even, the two middle chain plates 101 each have only one embedded area A, and one side of the connecting part of the two middle chain plates 101 is in line with one side of their respective main body, while the connecting parts of the chain plates 101 in other positions are offset from their respective main bodies towards the middle position (in the same direction as the offset of the connecting part and main body of the second chain plate).

[0067] Furthermore, referring to Figure 5 As shown, an embedding part 201 is provided on the second support plate 20, and the embedding part 201 is provided in the embedding area A of the chain plate 101 adjacent to the second support plate 20.

[0068] Specifically, the shape and size of the insert portion 201 are adapted to the shape and size of the insert area A of the chain plate 101, and a connecting pin 40 is also provided on the insert portion 201. The connecting pin 40 passes through the insert portion 201 and the main body portion 1011 of the chain plate 101 adjacent to the second support plate 20, thereby realizing the rotational connection between the second support plate 20 and the adjacent chain plate 101.

[0069] When the first support plate 10 bends along with the bending area of ​​the flexible display panel, in addition to the rotation between the chain plates 101, there may also be a situation where the chain plates 101 need to be relatively displaced. To deal with this situation, refer to Figure 8 As shown, in an optional embodiment, this application also provides a pivot support structure in which two adjacent chain plates 101 are rotatably connected by a connecting strip 50.

[0070] Specifically, refer to Figure 8As shown, the connecting portion 1012 of two adjacent chain plates 101 has an arc-shaped groove 70 at the adjacent position, and the arc-shaped groove 70 extends toward the main body portion 1011. In the two adjacent chain plates 101, a part of the arc-shaped groove 70 is located on the connecting portion of one chain plate, and the other part is located on the connecting portion of the other chain plate. That is, the connecting portion 1012 of two adjacent chain plates 101 each has a half arc-shaped groove 70.

[0071] Meanwhile, the connecting bar 50 is located within the arc-shaped groove 70, and the shape of the connecting bar 50 is adapted to the arc-shaped groove 70. The connecting bar 50 can slide relative to the groove 70, allowing adjacent chain plates 101 to rotate via the slidable connecting bar 50. The material of the connecting bar 50 can be a rigid material or an elastic material. When the connecting bar 50 is made of an elastic material, due to its own elasticity, a certain relative displacement can also occur between adjacent chain plates 101.

[0072] Therefore, compared to the first support plate 10 that connects two adjacent chain plates 101 via connecting pin 40, the first support plate 10 in this embodiment has better support in the flattened state (the bent area is in a straight state), which can reduce the situation where multiple chain plates 101 sink or deform greatly due to user touch.

[0073] At the same time, refer to Figure 8 and Figure 9 As shown, the embedded part 201 can also be connected to the adjacent chain plate 101 via the connecting strip 50. The connecting part 1012 between the embedded part 201 and the chain plate 101 adjacent to the second support plate 20 has an arc-shaped groove 70 at the adjacent position. The arc-shaped groove 70 extends toward the main body. The connecting strip 50 is located in the arc-shaped groove 70 and is adapted to the arc-shaped groove 70. In this way, the rotational connection between the second support plate 20 and the adjacent chain plate 101 can be realized. At the same time, when a relative displacement occurs between the second support plate 20 and the adjacent chain plate 101, the connecting strip 50 can also satisfy the relative displacement between the second support plate 20 and the adjacent chain plate 101.

[0074] Furthermore, referring to Figure 8 and Figure 10 As shown in the embodiment of this application, the end of the connecting bar 50 is provided to protrude from the edge of the connecting portion 1012, which allows the connecting bar 50 to undergo a certain displacement in the length direction of the chain plate 101, thereby making the rotation between two adjacent chain plates 101 or between the chain plate 101 and the second support plate 20 smoother.

[0075] In one alternative implementation, refer to Figure 7As shown in the embodiment of this application, a pivot support structure is also provided. In this pivot support structure, the surface of the chain plate 101 facing the flexible display panel is set as an arc-shaped surface, and the concave part of the arc-shaped surface faces the flexible display panel.

[0076] Specifically, since the bending area of ​​the flexible display panel is an arc-shaped surface after folding or bending, setting the surface of the chain plate 101 facing the flexible display panel as an arc-shaped surface makes the upper surface of the chain plate 101 (the surface of the chain plate 101 facing the flexible display panel) have a certain curvature, so that the upper surface of the chain plate 101 fits better with the bending area, further increasing the bonding area between the chain plate 101 and the flexible display panel, thereby further limiting the warping deformation of the flexible display panel.

[0077] Meanwhile, in this embodiment, the corners of the chain plate 101 located on both sides of the arc-shaped surface are rounded. This can further reduce the contact stress between the flexible display panel and the first support plate 10, thereby reducing the creases generated in the flexible display panel.

[0078] Based on the same inventive concept, this application discloses a display device, which may include a middle frame, a pivot mechanism, a flexible display panel (not shown in the figure), and the pivot support structure described above.

[0079] The hinge mechanism is located on the middle frame, which can fold as the hinge mechanism rotates; the hinge support structure is located on the middle frame and the hinge mechanism; and the flexible display panel is located on the hinge support structure and the middle frame. The specific structure of the hinge support structure has been described in detail above, so it will not be repeated here.

[0080] Specifically, the display device may include display devices such as liquid crystal displays, electronic paper, and OLED displays, as well as any product or component with display function, such as televisions, digital cameras, mobile phones, watches, tablets, laptops, and navigators, which include these display devices.
