Directional terms used in the present application, such as "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "side", etc., are merely directions referring to the attached drawings. Therefore, the directional terms used are used to explain and understand the present application, and are not intended to limit the present application. In the drawings, the same structural units are given the same reference numerals. In the drawings, the thicknesses of some layers and regions are exaggerated for clarity of understanding and ease of explanation. In other words, the dimensions and thicknesses of each member shown in the drawings are arbitrarily shown, and the present application is not limited thereto.

[0025] 1 to 16, the 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 body 100 is attached on the middle frame structure 20, which includes at least three middle frames, and every two adjacent middle frames are rotatably connected, and the hinge structure 30 includes at least two hinges, and each of the hinges is connected to two adjacent middle frames, where the torques of any two adjacent hinges are different. In this way, when folding the display panel 100, the hinges with smaller torque close first and the hinges with larger torque close last, thereby allowing the display panel 100 to be folded according to a preset folding order, avoiding damage to the display panel 100 caused by not folding according to the folding order, realizing mistake prevention when folding the display panel 100, and solving the problem that conventional foldable display devices are easily damaged when folded.

[0026] Hereinafter, a specific embodiment will be described to explain how to realize different torques of two adjacent hinges.

[0027] When the display panel 100 is in a first state, the at least three middle frames are sequentially arranged along a first direction X to form a flat surface to support and fix the main body of the flexible display panel 100. Any three adjacent middle frames are sequentially a first middle frame 21, a second middle frame 22 and a 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 by a first hinge 31, the third middle frame 23 is rotatably connected to the second middle frame 22 by a second hinge 32, and the torque of the first hinge 31 is smaller than the torque of the second hinge 32.

[0028] 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 to overlap 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 state, thereby reducing the area of ​​the display panel 100, improving the convenience of carrying, and solving the inconvenience of carrying that exists in the conventional large screen display device. Here, the first direction X is a horizontal direction, and the second direction Y is a vertical direction. Preferably, the first state is an unfolded state, and the second state is a curved state. When the display panel 100 is in the unfolded state, a large screen display of the display panel 100 is realized, and when the display panel 100 is in the curved state, a partial display or folding function of the display panel 100 is realized.

[0029] Hereinafter, the structure of the display panel 100 will be described in detail by taking an example in which the middle frame includes three middle frames.

[0030] 1 to 3, FIG. 1 is a schematic diagram of a planar structure of a display panel provided by an embodiment of the present application, FIG. 2 is a structure of the display panel with the flexible display panel body in FIG. 1 removed, and FIG. 3 is an exploded schematic diagram of the display panel in FIG. 1. As shown in FIG. 1, the flexible display panel body 10 includes a first part 11, a second part 12, a third part 13, a first flexible part 14 connected to the first part 11 and the second part 12, and a second flexible part 15 connected to the second part 12 and the third part 13. The first part 11, the first flexible part 14, the second part 12, the second flexible part 15, and the third part 13 are sequentially arranged along the first direction X. The flexible display panel body 10 includes a bendable and foldable screen, such as a flexible OLED display screen, and when the flexible display panel body 10 is a flexible OLED display screen, the flexible display panel 100 may include film layers, such as a driving circuit layer, a light-emitting functional layer, and a sealing layer, which are stacked together.

[0031] The flexible display panel main body 10 is attached on 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, which are sequentially arranged along the first direction X. As shown in FIG. 2, the hinge structure 30 includes the first hinge 31 and the second hinge 32, and 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. Here, the first middle frame 21 corresponds to the first part 11 of the flexible display panel main body 10, the second middle frame 22 corresponds to the second part 12, the third middle frame 23 corresponds to the third part 13, the first hinge 31 corresponds to the first flexible part 14, and the second hinge 32 corresponds to the second flexible part 15.

[0032] Preferably, referring to FIG. 3, the display panel 100 further includes a rear cover provided on a side of the middle frame structure 20 facing away from the flexible display panel body 10, the rear cover including a first rear cover 41, a second rear cover 42 and a third rear cover 43, the first rear cover 41 being removably connected to the first middle frame 21, the second rear cover 42 being removably connected to the second middle frame 22, and the third rear cover 43 being removably connected to the third middle frame 23.

[0033] 4 and 5, FIG. 4 is a schematic diagram of a cross-sectional structure of a display panel provided by an embodiment of the present application when it is in a first state, and FIG. 5 is a schematic diagram of a cross-sectional structure of a display panel provided by an embodiment of the present application when it is in a 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 fix the flexible display panel body 10, and the flexible display panel body 10 is in an unfolded 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 to overlap 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. That is, in the process of switching the display panel 100 from the first state to the second state, the first middle frame 21 rotates relative to the second middle frame 22, further bending the first flexible part 14 of the display panel 100, and the first part 11 faces the second part 12, and the third middle frame 23 rotates relative to the second middle frame 22, further bending the second flexible part 15 of the display panel 100, and the third part 13 faces the side of the first middle frame 21 that is away from the first part 11. In this way, when the display panel 100 is in the second state, the first part 11 is located between the second part 12 and the third part 13, and the display panel 100 is formed into a "G"-shaped three-fold form with a three-layer laminated structure, thereby reducing the area of ​​the display panel 100 and improving portability.

[0034] Preferably, 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, thereby avoiding interference between the first middle frame 21 and the second hinge 32, and 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 flush with the outer boundary of the display panel 100 as much as possible, thereby ensuring the aesthetic appearance of the display panel 100 after it is folded.

[0035] Preferably, 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, the thickness of the third middle frame 23 gradually decreases along the first direction X, and the thickness of the first middle frame 21 on a side closer to the first hinge 31 is greater than the thickness of the first middle frame 21 on a side farther from the first hinge 31. Specifically, a first inclined surface 210 is formed on a side of the first middle frame 21 that is away from the flexible display panel body 10, and a second inclined surface 230 is formed on a side of the third middle frame 23 that is 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 faces the thinner portion of the third middle frame 23, and the thinner portion of the first middle frame 21 faces the thinner portion of the third middle frame 23, thus making it possible to reduce the overall thickness of the display panel 100 after folding.

[0036] In one embodiment, one of the first hinge 31 and the second hinge 32 is a drop-shaped hinge and the other is a U-shaped hinge, where a drop-shaped hinge is a hinge that is curved in a drop-shaped manner after closing, and a U-shaped hinge is a hinge that is curved in a U-shaped manner after closing. However, the present application is not limited thereto, and the first hinge 31 and the second hinge of the present application may be the same type of hinge, for example, both are drop-shaped hinges or U-shaped hinges. The embodiment of the present application will be described using an example in which the first hinge 31 is a drop-shaped hinge and the second hinge 32 is a U-shaped hinge.

[0037] Furthermore, the torque of the first hinge 31 is smaller than the torque 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 closes first since the torque is smaller, and the second hinge 32 closes later since the torque is larger, thereby folding the display panel 100 according to a preset folding sequence and avoiding damage to the display panel 100 caused by not folding according to the folding sequence.

[0038] The structures of the first hinge 31 and the second hinge 32 will be specifically described below.
