[0060] The following descriptions of the embodiments are with reference to the attached diagrams to illustrate specific embodiments that the present application can be implemented in. The directional terms mentioned in this application, such as [up], [down], [front], [back], [left], [right], [inside], [outside], [side], etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present application, rather than to limit the present application. In the figures, units with similar structures are represented by the same reference numerals. In the accompanying drawings, the thickness of some layers and areas is exaggerated for clarity of understanding and ease of description. That is, the size and thickness of each component shown in the drawings are arbitrarily shown, but the present application is not limited to this.

[0061] Please refer to Figures 1 to 16The present application provides a foldable display panel 100, which includes a flexible display panel body 10, a middle frame structure 20, and a hinge structure 30. The flexible display panel 100 body is attached to the middle frame structure 20, and the middle frame structure 20 includes at least three middle frames, and each two adjacent middle frames are rotatably connected. The hinge structure 30 includes at least two hinges, and each hinge is connected to two adjacent middle frames. The torsional forces of any two adjacent hinges are different. In this way, when the display panel 100 is folded, the hinge with smaller torsional force closes first, and the hinge with larger torsional force closes later, so that the display panel 100 can be folded according to a preset folding order, avoiding damage to the display panel 100 caused by folding not in accordance with the folding order, so as to achieve fool-proofing when the display panel 100 is folded, and solve the problem that the existing folding display device is easily damaged when folding.

[0062] The following will use a specific implementation method to illustrate how to achieve different torsional forces between two adjacent hinges.

[0063] When the display panel 100 is in the first state, the at least three middle frames are arranged in sequence along the first direction X to form a flat surface to support and fix the flexible display panel 100 body. Any three adjacent middle frames are the first middle frame 21, the second middle frame 22, and the third middle frame 23. The second middle frame 22 is located between the first middle frame 21 and the third middle frame 23. The first middle frame 21 is rotatably connected to the second middle frame 22 via a first hinge 31, and the third middle frame 23 is rotatably connected to the second middle frame 22 via a second hinge 32. The torsional force of the first hinge 31 is less than the torsional force of the second hinge 32.

[0064] When the display panel 100 is in the second state, the second middle frame 22, the first middle frame 21, and the third middle frame 23 are arranged in an overlapping manner in the second direction Y, and the first middle frame 21 is located between the second middle frame 22 and the third middle frame 23, so that the display panel 100 is in a folded form, thereby reducing the area of ​​the display panel 100 and improving the convenience of carrying, thereby solving the inconvenience of carrying existing large-screen display devices. The first direction X is the horizontal direction, and the second direction Y is the vertical direction. Optionally, the first state is the flattened state, and the second state is the bent state. When the display panel 100 is in the flattened state, the display panel 100 can be displayed on a large screen; when the display panel 100 is in the bent state, the display panel 100 can be partially displayed or folded.

[0065] The structure of the display panel 100 will be described in detail below by taking the example of the middle frame including three middle frames.

[0066] Reference Figures 1 to 3 , Figure 1 A schematic diagram of a top view of the display panel provided in an embodiment of the present application is shown. Figure 2 for Figure 1 The display panel structure after removing the flexible display panel body, Figure 3 for Figure 1 The flexible display panel body 10 includes a first portion 11, a second portion 12, a third portion 13, a first flexible portion 14 connected to the first portion 11 and the second portion 12, and a second flexible portion 15 connected to the second portion 12 and the third portion 13. Figure 1 As shown. The first portion 11, the first flexible portion 14, the second portion 12, the second flexible portion 15, and the third portion 13 are arranged sequentially along the first direction X. The flexible display panel body 10 includes a bendable or foldable screen such as a flexible OLED display screen. When the flexible display panel body 10 is a flexible OLED display screen, the flexible display panel 100 may include laminated film layers such as a driving circuit layer, a light-emitting functional layer, and an encapsulation layer.

[0067] The flexible display panel body 10 is attached to the middle frame structure 20, and the middle frame structure 20 includes the first middle frame 21, the second middle frame 22, and the third middle frame 23 arranged in sequence along the first direction X. The hinge structure 30 includes the first hinge 31 and the second hinge 32, the first hinge 31 is connected to the first middle frame 21 and the second middle frame 22, and the second hinge 32 is connected to the second middle frame 22 and the third middle frame 23. Figure 2 The first middle frame 21 corresponds to the first portion 11 of the flexible display panel body 10 , the second middle frame 22 corresponds to the second portion 12 , the third middle frame 23 corresponds to the third portion 13 , the first hinge 31 corresponds to the first flexible portion 14 , and the second hinge 32 corresponds to the second flexible portion 15 .

[0068] Optionally, refer to Figure 3 The display panel 100 also includes a back cover provided on the side of the middle frame structure 20 away from the flexible display panel body 10, the back cover includes a first back cover 41, a second back cover 42 and a third back cover 43, the first back cover 41 is detachably connected to the first middle frame 21, the second back cover 42 is detachably connected to the second middle frame 22, and the third back cover 43 is detachably connected to the third middle frame 23.

[0069] Reference Figure 4 and Figure 5 , Figure 4 A schematic cross-sectional view of a display panel in a first state according to an embodiment of the present application is shown. Figure 5 This is a schematic cross-sectional view of the display panel provided in an embodiment of the present application in its second state. When the display panel 100 is in the first state, the first middle frame 21, the second middle frame 22, and the third middle frame 23 are arranged along the first direction X to form a flat surface to support and secure the flexible display panel body 10 and keep the flexible display panel body 10 in a flat state. When the display panel 100 is in the second state, the second middle frame 22, the first middle frame 21, and the third middle frame 23 are arranged in an overlapping manner in the second direction Y, with the first middle frame 21 located between the second middle frame 22 and the third middle frame 23. That is, when the display panel 100 switches from the first state to the second state, the first middle frame 21 rotates relative to the second middle frame 22, thereby bending the first flexible portion 14 of the display panel 100, with the first portion 11 facing the second portion 12. The third middle frame 23 rotates relative to the second middle frame 22, thereby bending the second flexible portion 15 of the display panel 100, with the third portion 13 facing the side of the first middle frame 21 away from the first portion 11. Thus, when the display panel 100 is in the second state, the first portion 11 is located between the second portion 12 and the third portion 13, forming a "G"-shaped tri-fold structure with three layers of laminated structure, thereby reducing the area of ​​the display panel 100 and improving portability.

[0070] Optionally, in the first direction X, the length L1 of the first middle frame 21 is smaller than the length L2 of the second middle frame 22 to avoid interference between the first middle frame 21 and the second hinge 32; the length L2 of the second middle frame 22 is smaller than the length L3 of the third middle frame 23, so that after the display panel 100 is folded, the outer boundary of the third middle frame 23 is as flush as possible with the outer boundary of the display panel 100 to ensure the beautiful appearance of the display panel 100 after folding.

[0071] Optionally, when the display panel 100 is in the first state, the thickness of the first middle frame 21 gradually increases along the first direction X, while the thickness of the third middle frame 23 gradually decreases along the first direction X. Furthermore, the thickness of the first middle frame 21 on the side closest to the first hinge 31 is greater than the thickness of the first middle frame 21 on the side farther from the first hinge 31. Specifically, a first inclined surface 210 is formed on the side of the first middle frame 21 facing away from the flexible display panel body 10, and a second inclined surface 230 is formed on the side of the third middle frame 23 facing away from the flexible display panel body 10. When the display panel 100 is in the second state, due to the presence of the first inclined surface 210 and the second inclined surface 230, the thicker portion of the first middle frame 21 is opposite the thinner portion of the third middle frame 23, and vice versa. This reduces the overall thickness of the display panel 100 after folding.

[0072] In one embodiment, one of the first hinge 31 and the second hinge 32 is a teardrop-shaped hinge, and the other is a U-shaped hinge. A teardrop-shaped hinge refers to a hinge that is teardrop-shaped when closed; a U-shaped hinge refers to a hinge that is U-shaped when closed. However, the present application is not limited thereto. The first hinge 31 and the second hinge of the present application may also be hinges of the same type, such as both being teardrop-shaped hinges or U-shaped hinges. The present embodiment takes the example of the first hinge 31 being a teardrop-shaped hinge and the second hinge 32 being a U-shaped hinge.

[0073] Furthermore, the torsion of the first hinge 31 is smaller than the torsion of the second hinge 32. Thus, when the same external force is applied to switch the display panel 100 from the first state to the second state, the first hinge 31 will close first due to the smaller torsion, and the second hinge 32 will close later due to the larger torsion. This allows the display panel 100 to be folded in a preset folding order, avoiding damage to the display panel 100 due to folding not in accordance with the folding order.

[0074] The structures of the first hinge 31 and the second hinge 32 will be described in detail below:

[0102] Please refer to Figures 1 to 18 , Figure 17 This is a torque simulation curve diagram of the first hinge provided in an embodiment of the present application.

The display panel 100 can be folded according to a preset folding order, avoiding damage to the display panel 100 due to folding not in accordance with the folding order, and realizing the anti-foolproof function of the display panel 100 when folding.
