[0028] It should be noted that, for the convenience of explanation, in the embodiments of the present application, the same figure marks represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0029] The present application provides a flexible display assembly, comprising: a flexible display, a protective frame, a sealing structure and a hinge protection shell; the flexible display comprises a bending area; the protective frame is arranged around the periphery of the flexible display, and the protective frame is provided with two openings corresponding to the bending area; the sealing structure comprises two first elastic bodies, the bodies of the two first elastic bodies are respectively covered on the surfaces of the flexible display corresponding to the two openings, and the bodies of the first elastic bodies are extended to form an extension portion; the hinge protection shell is provided with a receiving groove, and the extension portion is received in the receiving groove.

[0032] In some embodiments, the flexible display screen 10 can be an organic light-emitting diode (OLED) display screen, an active matrix organic light-emitting diode (AMOLED) display screen, a super active matrix organic light-emitting diode (Super AMOLED) display screen or a super active matrix organic light-emitting diode Plus (Super AMOLED Plus) display screen. AMOLED, Super AMOLED or Super AMOLED Plus display screens are self-luminous display screens and do not need to be provided with a backlight module (BLM). Therefore, the flexible display screen 10 preferably adopts an AMOLED, Super AMOLED or Super AMOLED Plus display screen to have better flexibility. In some embodiments, the substrate of the AMOLED, Super AMOLED or Super AMOLED Plus display screen can be made of a flexible resin material, such as polyethylene terephthalate (PET), so as to have a bendable characteristic.

[0033] like Figure 2 As shown, the flexible display screen 10 also includes a first non-bending area 102 and a second non-bending area 103, the first non-bending area 102 is connected to the second non-bending area 103 through the bending area 101, and the bending area 101 is used for bending or unfolding the flexible display screen 10; wherein, the bending center line along which the flexible display screen 10 is bent is defined as the bending axis of the flexible display screen 10.

[0034] The protective frame 20 is used to protect the edge of the flexible display screen 10 , and the material of the protective frame 20 may be resin, metal, or silicone, etc. In some embodiments, the protective frame 20 may also have a specific color and a specific pattern, so as to decorate the flexible display screen 10 .

[0035] In some embodiments, see Figure 2 , Figure 3 and Fig. 9The protective frame 20 includes a first frame 21 and a second frame 22, the first frame 21 is pressed on the edge of the flexible display screen 10 corresponding to the first non-bending area 102, and the second frame 22 is pressed on the edge of the flexible display screen 10 corresponding to the second non-bending area 103; in some embodiments, the ends of the first frame 21 and the second frame 22 extend into the bending area 101, and the ends of the first frame 21 and the second frame 22 are spaced apart to form the opening 201; of course, in other embodiments, the ends of the first frame 21 and the second frame 22 may not extend into the bending area 101.

[0036] In some embodiments, see Fig. 9 The shape of the flexible display screen 10 is a rectangle, so the shapes of the first frame 21 and the second frame 22 can be respectively in the shape of “[”.

[0037] The flexible display screen has a smaller size after being bent, which can make it more convenient. After being unfolded, it can provide a larger display area and more display information. In some embodiments, the flexible display screen 10 can be an outward-folding display screen, that is, the display surface faces the outside when the flexible display screen 10 is bent. In some embodiments, the flexible display screen 10 may include multiple film layers, such as a display layer, an isolation layer, a touch layer, etc. When bent, the stress conditions of each film layer of the flexible display screen 10 are completely different, wherein the inner surface is subjected to compressive stress as a compressive stress layer, and the outer surface is subjected to tensile stress as a tensile stress layer. When the flexible display screen 10 is unfolded, the outer surface needs to shrink inward and return to its original position, and the inner surface needs to stretch and return to its original position. If the flexible display screen 10 is subjected to uneven force, it is easy to cause the separation of the film layer, thereby causing the entry of water vapor or dust, causing the flexible display screen 10 to fail due to bad points.

[0038] In the present application, the first elastic body 31 is a structure made of a flexible and elastic material; see Fig. 9 , Fig.11 and Fig.12, the first elastic body 31 includes a main body 311 and an extension portion 312 extending from the main body 311; wherein, the main bodies 311 of the two first elastic bodies 31 are respectively covered on the surfaces of the two corresponding openings 201 of the flexible display screen 10, so that the edges of the bending zone 101 of the flexible display screen 10 corresponding to the opening 201 are protected by the first elastic body 31, that is, the first elastic body 31 seals the opening 201; and, the extension portion 312 of the first elastic body 31 is received in the receiving groove 401 of the rotating shaft protection shell 40, so that the first elastic body 31 is limited to the opening 201, so that when the flexible display screen 10 is bent, the bending zone 101 is fixed to the first elastic body 31 as a whole, so that on the one hand, the stress concentration at the bending zone 101 can be weakened, and on the other hand, the stress unevenness between the film layers of the flexible display screen 10 at the bending zone 101 can be prevented, the delamination between the film layers of the flexible display screen 10 is suppressed, and the flexible display screen 10 is prevented from entering water and dust.

[0039] In some embodiments, see Fig.11 and Fig.12 , a plurality of grooves 301 are formed on the surface of the body 311 of the first elastic body 31 away from the flexible display screen 10, and the plurality of grooves 301 extend in the same direction as the bending axis of the flexible display screen 10, and the plurality of grooves 301 are used to make the first elastic body 31 easy to bend following the flexible display screen 10; in a preferred embodiment, in a direction perpendicular to the bending axis of the flexible display screen 10, the side of the cross-section of the body 311 of the first elastic body 31 away from the flexible display screen 10 is serrated, that is, the plurality of grooves 301 are distributed in a serrated shape, so that the first elastic body 31 is subjected to more uniform force when bent.

[0040] In some embodiments, see Figure 5 , Figure 6 , Fig. 9 and Fig.10 The sealing structure 30 further includes two second elastic bodies 32 connected between the two first elastic bodies 31. The two second elastic bodies 32 are tightly sandwiched between the protection frame 20 and the flexible display screen 10.

[0042] In some embodiments, the thickness of the two second elastic bodies 32 is greater than or equal to the depth of the receiving groove 202 , so that the second elastic body 32 can completely fill the receiving groove 202 .

[0043] In a preferred embodiment, the thickness of the two second elastic bodies 32 is greater than or equal to the depth of the receiving groove 202, so that the second elastic body 32 and the receiving groove 202 are interference fit, and when the second elastic body 32 is clamped between the protective frame 20 and the flexible display screen 10, the second elastic body 32 can be compressed so as to be tightly accommodated between the receiving groove 202 and the flexible display screen 10, thereby preventing water or dust from entering between the flexible display screen 10 and the protective frame 20.

[0044] In a more preferred embodiment, the thickness of the two second elastic bodies 32 is 1.1 to 1.2 times the depth of the receiving groove, so that the second elastic bodies 32 can better prevent water or dust from entering between the flexible display screen 10 and the protective frame 20.

[0045] In the present application, the extension portion 312 is received in the receiving groove 401, so that the first elastic body 31 can clamp the flexible display screen 10 more tightly, preventing the first elastic body 31 from loosening and forming a gap between the flexible display screen 10 when the flexible display screen 10 is bent, and preventing water vapor and dust from entering the flexible display screen 10 through the gap.

[0046] In some embodiments, see Fig.14, the extension direction of the extension portion 312 is approximately perpendicular to the extension direction of the flexible display screen 10.

The extension portion 312 extends vertically downward from the main body 311, that is, the extension portion 312 extends from the main body 311 toward the second surface 105 of the flexible display screen 10.

[0047] In some embodiments, the two ends of the hinge protective shell 40 extend out of the flexible display screen 10, or in other words, the hinge protective shell 40 is arranged along the bending axis direction of the flexible display screen 10, and in the bending axis direction of the flexible display screen 10, the length of the hinge protective shell 40 is greater than the length of the flexible display screen 10, so that the two ends of the hinge protective shell 40 along the bending axis direction of the flexible display screen 10 protrude from the flexible display screen 10; wherein the receiving groove 401 is arranged at the two ends of the hinge protective shell 40 extending out of the flexible display screen 10, and the depth direction of the receiving groove 401 is approximately perpendicular to the extension direction of the flexible display screen 10.

[0048] In some other embodiments, see Fig.15 The extension direction of the extension portion 312 may also be roughly parallel to the extension direction of the flexible display screen 10. The receiving groove 401 is arranged at the two ends of the hinge protection shell 40. The depth direction of the receiving groove 401 is also roughly parallel to the flexible display screen 10, so that the flexible display screen 10 is clamped between the main body 311 of the first elastomer 31 and the extension portion 312.

[0049] Specifically, the main body 311 is roughly flat and roughly parallel to the flexible display screen 10. The main body 311 extends downward to form a connecting portion, and then the extending portion 312 is formed from the connecting portion in a direction parallel to the flexible display screen 10; the two ends of the hinge protective shell 40 can slightly extend out of the flexible display screen 10 or be roughly flush with the flexible display screen 10, or in other words, the hinge protective shell 40 is arranged along the bending axis direction of the flexible display screen 10, and in the bending axis direction of the flexible display screen 10, the length of the hinge protective shell 40 is equivalent to the length of the flexible display screen 10, or the length of the hinge protective shell 40 is slightly larger than the length of the flexible display screen 10, and the receiving groove 401 is arranged at the two ends of the hinge protective shell 40 extending out of the flexible display screen 10, and the depth direction of the receiving groove 401 is roughly parallel to the extension direction of the flexible display screen 10, so that the extending portion 312 can be accommodated in the receiving groove 401.

[0052] The fixing member 50 may be formed on a bottom surface of the extending portion 312 in the extending direction, or may be formed on a side surface of the extending portion 312 in the extending direction.

[0053] In some embodiments, Fig.14 As shown, the extension direction of the extension portion 312 is substantially perpendicular to the extension direction of the flexible display screen 10, and the fixing member 50 is convexly arranged on the surface of the extension portion 312 away from the main body 311, that is, the fixing member 50 is convexly arranged on the bottom of the first elastic body 31; the depth direction of the receiving groove 401 is substantially perpendicular to the extension direction of the flexible display screen 10, and the bottom wall of the receiving groove 401 is concavely provided with a receiving groove 402, and the fixing member 50 is received and fixed in the receiving groove 402, that is, the receiving groove 401 and the receiving groove 402 are both substantially along the self- The first surface 104 of the flexible display screen 10 extends in the direction of the second surface 105; in other embodiments, the fixing member 50 may also be protruded from the side of the extension portion 312, so that the extension direction is roughly parallel to the extension direction of the flexible display screen 10, that is, the fixing member 50 is protruded from the side of the first elastic body 31; correspondingly, the side wall of the receiving groove 401 is recessed with a receiving groove 402, and the fixing member 50 is received and fixed in the receiving groove 402, that is, the receiving groove 401 is roughly perpendicular to the extension direction of the receiving groove 402.

[0054] In some other embodiments, Fig.15 As shown, the extension direction of the extension portion 312 is substantially parallel to the extension direction of the flexible display screen 10, and the fixing member 50 is convexly provided on the side of the extension portion 312 facing the flexible display screen 10, so that the extension direction is substantially perpendicular to the extension direction of the flexible display screen 10; the depth direction of the receiving groove 401 is substantially parallel to the extension direction of the flexible display screen 10, and the side wall of the receiving groove 401 is concavely provided with a receiving groove 402, and the fixing member 50 is received and fixed in the receiving groove 402, That is, the extension direction of the receiving groove 401 is approximately perpendicular to that of the receiving groove 402; in other embodiments, the fixing member 50 may also be protruded from the bottom of the extension portion 312, so that the extension direction is approximately parallel to the extension direction of the flexible display screen 10; the bottom wall of the receiving groove 401 perpendicular to the flexible display screen 10 is recessed with a receiving groove 402, and the fixing member 50 is received and fixed in the receiving groove 402, that is, the extension direction of the receiving groove 401 is approximately the same as that of the receiving groove 402.

[0056] In some embodiments, the fixing member 50 is fixed in the receiving groove 402 by glue; in some feasible processes, for example, glue can be dispensed in the receiving groove 402 first, and then the fixing member 50 is placed in the receiving groove 402 and the extension portion 312 of the first elastomer 31 is accommodated in the receiving groove 401, and the glue can be cured to fix the fixing member in the receiving groove 402.

[0057] In some embodiments, the protection frame 20, the sealing structure 30 and the fixing member 50 may be an integral structure formed by an integral molding process.

[0058] In some embodiments, the sealing structure 30 and the fixing part 50 can be made of the same material. In this case, the protective frame 20 can be prefabricated, and then the protective frame 20 is placed in an injection mold, and the molding glue is injected onto the protective frame 20, and the sealing structure 30 and the fixing part 50 are molded in the mold cavity to obtain the integrated structure.

[0059] In some preferred embodiments, the material hardness of the fixing part 50 can be greater than the material hardness of the sealing structure 30, so that the fixing part 50 has a better fixing effect; at this time, the protective frame 20 and the fixing part 50 can be prefabricated, and then the protective frame 20 and the fixing part 50 are placed in an injection mold, and the injection molding glue is injected onto the protective frame 20 and the fixing part 50, and the sealing structure 30 is formed in the mold cavity to obtain the integrated structure.

[0060] In some preferred embodiments, Figure 5 As shown, the fixing part 50 can be partially buried in the extension part 312 and partially protruded from the extension part 312; when the above-mentioned direction is adopted to form the integrated structure, for example, the injection molding liquid can partially wrap the fixing part 50, so that the fixing part 50 is partially buried in the extension part 312.

[0061] In some embodiments, the length of the portion of the fixing member 50 buried in the extension portion 312 is greater than the length of the portion of the fixing member 50 exposed in the extension portion 312 , so that the fixing member 50 is more secure.

[0062] In some embodiments, the fixing member 50 is a columnar body, for example, the fixing member 50 is cylindrical; of course, the fixing member 50 can also be a triangular prism, a rectangular parallelepiped, a polygonal prism, a semi-cylindrical shape, etc., and is not limited to the above.

[0063] In some embodiments, the fixing member 50 is located in the middle of the extending portion 312 so that the first elastic body 31 is subjected to a more balanced force when being bent.

[0064] In a preferred embodiment, the sealing structure is formed by curing two-component liquid silicone rubber (LSR); and the material of the fixing member is hard plastic or metal.

[0065] Among them, see Fig.13 The LSR injection molding process can be, for example: two liquid silicone rubber raw materials A and B are accurately metered and transported to a mixing device through a metering device; the two components are fully mixed in the mixer and then transported to an injection molding machine; the molding machine injects or sprays them into a preheated multi-mold and evenly distributes them to each mold cavity; the silicone rubber material is heated in the hot mold cavity and quickly vulcanized to form a product; the mold is automatically opened and ejected after vulcanization molding; then the mold is closed and enters the next molding cycle.

[0066] In some embodiments, Figures 3 to 6As shown, the flexible display screen assembly 100 further includes a first shell 61 and a second shell 62. In some embodiments, a portion of the flexible display screen 10 is fixed to the first shell 61, a portion is fixed to the second shell 62, and the remaining portion of the flexible display screen 10 is located between the first shell 61 and the second shell 62; wherein the flexible display screen 10 can be fixed to the first shell 61 and the second shell 62 by adhesive.

[0067] The first shell 61 and the second shell 62 are used to carry the flexible display screen 10 to ensure the flatness of the flexible display screen 10 and protect the non-display surface of the flexible display screen 10; the first shell 61 and the second shell 62 do not have a bending property, and the area on the flexible display screen 10 connected to the first shell 201 cannot be bent. Figure 2 The first non-bending area 102 shown in FIG. 1 is an area on the flexible display screen 10 connected to the second shell 202 and cannot be bent. Figure 2 The second non-bending area 103 shown, the portion of the flexible display screen 10 located between the first non-bending area 102 and the second non-bending area 103, is the bending area 101 that enables the terminal device to achieve bending characteristics.

[0068] In some embodiments, Figure 3 , Figure 5 , Figure 6 As shown in the figures, the hinge protection shell 40 is roughly semi-cylindrical, and includes a semi-cylindrical surface 41. The first shell 61 and the second shell 62 are respectively formed with a groove 611 and a groove 621 corresponding to the semi-cylindrical surface 41, so that the hinge protection shell 40 is accommodated in the grooves 611 and 621 of the first shell 61 and the second shell 62, so that the overall appearance of the first shell 61, the second shell 62 and the flexible display screen 10 after being surrounded is flat.

[0069] In some embodiments, Figure 6 As shown, the flexible display screen assembly 100 is also located at a rotating shaft 70 between the first shell 61 and the second shell 62 , and the rotating shaft 70 is accommodated in the rotating shaft protection shell 40 .

[0070] In some embodiments, there is a gap between the rotating shaft 70 and the rotating shaft protection shell 40, so that the rotating shaft 70 can rotate in the rotating shaft protection shell 40.
