Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0052] like Figure 1As shown, Figure 1 A schematic diagram of a display device is shown, comprising a flexible screen 20 and a curved cover plate 10 bonded together. In some current applications, the flexible screen 20 needs to be bonded to a spherical curved cover plate 10 or a large-curvature curved cover plate 10. During this process, the bonding precision between the flexible screen 20 and the curved cover plate 10 is difficult to control, leading to premature contact and poor bonding.

[0053] To address the aforementioned technical problems, this application is proposed. For a better understanding of this application, the following is combined with... Figures 2 to 9 The supporting component, bonding device, and bonding method of the embodiments of this application will be described in detail.

[0054] like Figures 2 to 6 As shown, one embodiment of this application provides a support component for fitting a curved cover plate 10 and a flexible screen 20. The support component includes a base 100, a bracket 200, and a flexible support platform 300. The bracket 200 is connected to one side of the base 100; the flexible support platform 300 is connected to the side of the bracket 200 away from the base 100. The flexible support platform 300 has a support surface 350 for supporting the flexible screen 20. The bracket 200 is used to deformably set the flexible support platform 300 between a first state and a second state. The curvature of the support surface 350 in the first state is less than its curvature in the second state.

[0055] In the support component provided in this embodiment, the support component is used to support the flexible screen 20 during the bonding process between the curved cover plate 10 and the flexible screen 20. The flexible support platform 300 includes a base 100, a bracket 200, and a flexible support platform 300. The base 100 provides support, and the bracket 200 connects the base 100 and the flexible support platform 300. The support surface 350 of the flexible support platform 300 supports the flexible screen 20. The bracket 200 allows the flexible support platform 300 to be deformably configured between a first state and a second state, and the curvature of the support surface 350 in the first state is less than its curvature in the second state, so that the support surface 350 can change the curvature of the flexible screen 20, thereby improving the bonding yield between the flexible screen 20 and the curved cover plate 10.

[0056] Optional, such as Figure 3 and Figure 4As shown, the flexible support platform 300 can be switched between a first state and a second state. The flexible support platform 300 has a support surface 350 for supporting the flexible screen 20. The curvature of the support surface 350 in the second state is greater than its curvature in the first state. Optionally, the first state can be a flattened state, in which the support surface 350 is planar, allowing the flexible screen 20 to better fit the flexible support platform 300. The second state is a curved state, in which the support surface 350 can be a curved surface, a sphere, etc., and its shape can be adapted to the shape of the curved cover plate 10. In other embodiments, in the first state, the support surface 350 can also be curved to reduce the deformation of the support surface 350 when transitioning from the first state to the second state. This application embodiment illustrates the first state as planar and the second state as curved.

[0057] Optionally, the shape of the support surface 350 can be adapted to the shape of the curved cover plate 10. For example, when the curved cover plate 10 is a spherical cover plate, that is, when the surface of the curved cover plate 10 used to adhere to the flexible screen 20 is part of a spherical surface, in the first state, the support surface 350 can be a circular plane, and in the second state, the support surface 350 can be part of a spherical surface. When the surface of the curved cover plate 10 used to adhere to the flexible screen 20 is part of an arc surface, for example, when the surface of the curved cover plate 10 used to adhere to the flexible screen 20 is part of a cylindrical surface, in the first state, the support surface 350 can be rectangular, and in the second state, the support surface 350 can be part of a cylindrical surface.

[0058] In some alternative embodiments, in the first state, the support surface 350 may also be curved, and in the second state, the support surface 350 is also curved, and the curvature of the support surface 350 in the first state is less than the curvature in the second state.

[0059] There are multiple ways to set the base 100. The base 100 can be made of rigid materials such as metal or plastic, so that the base 100 can provide good support for the bracket 200 and the flexible support platform 300.

[0060] Optionally, the flexible support platform 300 includes a deformable wall portion 310 and a receiving cavity 320 formed by the wall portion 310. The receiving cavity 320 is filled with a movable first medium 330 and a second medium 340, and at least a portion of the first medium 330 and the second medium 340 are immiscible.

[0061] In these optional embodiments, a first medium 330 and a second medium 340 are disposed within the wall portion 310 of the flexible support platform 300, and at least a portion of the first medium 330 and the second medium 340 are immiscible. When the flexible support platform 300 is in a bent state, the first medium 330 can converge at the bend apex of the flexible support platform 300 in the bent state, and the flexible screen 20 at the bend apex contacts and adheres to the curved cover plate 10. After the flexible screen 20 and the curved cover plate 10 adhere to each other at the bend apex of the flexible support platform 300 in the bent state, when the flexible support platform 300 is further compressed, the first medium 330 will move and compress the second medium 340 through the deformation of the wall portion 310, causing the flexible screen 20 and the curved cover plate 10 to gradually adhere to each other from the apex to the periphery of the apex.

[0062] Optionally, the mass of the first medium 330 is less than the mass of the second medium 340.

[0063] In these optional embodiments, a first medium 330 and a second medium 340 of different masses are disposed within the wall 310 of the flexible support platform 300. When the flexible support platform 300 is in a bent state, the first medium 330 has a smaller mass, making it easier for the first medium 330 to gather at the bending apex of the flexible support platform 300 in the bent state, where the flexible screen 20 on the bending apex contacts and adheres to the curved cover plate 10.

[0064] Optionally, the wall portion 310 may be made of a transparent material to allow the positions of the first medium 330 and the second medium 340 to be observed through the wall portion 310.

[0065] Optional, such as Figure 4 As shown, the receiving cavity 320 includes a first segment 321 and a second segment 322 located on the periphery of the first segment 321. The first medium 330 is located in the first segment 321. In the second state, the bending apex of the flexible support platform 300 is located in the first segment 321.

[0066] In these embodiments, in the second state, the bending vertex of the flexible support platform 300 is in the first segment 321, and the first medium 330 with a smaller mass is located in the first segment 321. After the flexible screen 20 and the curved cover plate 10 are bonded together, when the flexible support platform 300 is further compressed, the first medium 330 will move and compress the second medium 340 through the deformation of the wall portion 310, so that the flexible screen 20 and the curved cover plate 10 gradually bond to each other from the vertex to the periphery of the vertex, which can improve the bonding yield of the flexible screen 20 and the curved cover plate 10.

[0067] Optionally, in the first state, the first medium 330 is located in the first segment 321, and the second medium 340 is located in the second segment 322. There is no specific boundary between the first segment 321 and the second segment 322, as long as in the second state, the bending vertex is located in the first segment 321, the first medium 330 is located in the first segment 321, and the second medium 340 is located in the second segment 322.

[0068] Optionally, when the support surface 350 is a circular plane in the first state, the first segment 321 can pass through the center of the support surface 350, and the second segment 322 is located around the first segment 321 and is arranged around the first segment 321. When the support surface 350 is rectangular in the first state, the first segment 321 can be strip-shaped and pass through the center line of the support surface 350, and the second segment 322 is located on both sides of the first segment 321 and is strip-shaped. In the second state, the first segment 321 is bent, the bending apex of the flexible support platform 300 is located on the first segment 321, and the two second segments 322 are respectively arranged on both sides of the first segment 321, and the inclination directions of the two second segments 322 are opposite.

[0069] There are various ways to arrange the first medium 330 and the second medium 340. For example, the first medium 330 may comprise a gas, making its mass sufficiently light; and / or the second medium 340 may comprise a liquid, making its mass relatively large and easily movable within the receiving cavity 320. As an optional embodiment, the first medium 330 may comprise nitrogen, making it colorless, odorless, non-toxic, and sparingly soluble in water. Optionally, the second medium 340 may comprise water, making it colorless, odorless, non-toxic, and readily available.

[0070] There are several ways to set up the bracket 200. The bracket 200 can support only the middle part of the flexible support platform 300. By utilizing the deformation of the flexible support platform 300 itself, the flexible screen 20 and the curved cover plate 10 gradually fit together from the middle of the flexible support platform 300 toward its periphery.

[0071] In other embodiments, the bracket 200 is provided with a plurality of support ends 201 at one end away from the base 100, and the flexible support platform 300 is connected to the plurality of support ends 201. The relative positions of the plurality of support ends 201 are adjustable so that the flexible support platform 300 can change between a first state and a second state.

[0072] In these optional embodiments, the bracket 200 is provided with a plurality of support ends 201 for supporting the flexible support platform 300, and the relative positional relationship of the flexible support ends 201 is adjusted.

[0073] For example, such as Figure 2 and Figure 3As shown, by placing multiple support ends 201 on the same plane, the flexible support platform 300 is positioned as follows: Figure 5 The first state is shown; then, by changing the relative positions between the multiple support ends 201, such as... Figure 4 As shown, the position of the support end 201 supporting the center of the flexible support platform 300 remains unchanged. For example, the position of at least one support end 201 supporting the first segment 321 remains unchanged. The support ends 201 supporting the edges of the flexible support platform 300 move toward the base 100. For example, the support end 201 supporting the second segment 322 moves toward the base 100, thereby causing the flexible support platform 300 to change from the first state to the second state. Figure 6 The second state is shown.

[0074] This application embodiment can more accurately adjust the deformation of the flexible support platform 300 by changing the relative positional relationship of multiple support ends 201, thereby improving the bonding accuracy of the flexible screen 20 and the curved cover plate 10, and thus improving the bonding yield of the flexible screen 20 and the curved cover plate 10.

[0075] There are several ways to adjust the relative positions of the multiple support ends 201 on the bracket 200. For example, the bracket 200 includes multiple support rods, each of which can be extended or retracted. The multiple support rods are supported between the base 100 and the flexible support platform 300. By adjusting the length of the support rods, the relative positions of the multiple support ends 201 can be adjusted.

[0076] In some other alternative embodiments, such as Figures 2 to 4 As shown, the support 200 includes a main rod 210 and secondary rods 220. One end of the main rod 210 is connected to the base 100, and the other end of the main rod 210 is connected to multiple secondary rods 220. The support end 201 is the end of the secondary rod 220 away from the main rod 210 and used to connect to the flexible support platform 300. The secondary rods 220 are rotatably disposed around the main rod 210, and / or at least one secondary rod 220 includes a first sub-rod 221 and a second sub-rod 222 sequentially connected in the direction from the main rod 210 to the flexible support platform 300. The second sub-rod 222 is rotatably disposed around the first sub-rod 221. Optionally, when the secondary rod 220 includes a first sub-rod 221 and a second sub-rod 222, the second sub-rod 222 is used to connect to the flexible support platform 300, and the support end 201 is located on the second sub-rod 222.

[0077] In these optional embodiments, when the bracket 200 includes a main rod 210 and a secondary rod 220, the secondary rod 220 is rotatably configured about the main rod 210. By adjusting the angle between the secondary rod 220 and the main rod 210, the relative positions of the multiple support ends 201 can be adjusted. When the secondary rod 220 includes a first sub-rod 221 and a second sub-rod 222, the second sub-rod 222 is rotatably configured about the first sub-rod 221. By adjusting the angle between the second sub-rod 222 and the first sub-rod 221, the relative positions of the multiple support ends 201 can also be adjusted.

[0078] like Figure 2 As shown, the secondary rod 220 may not include the first sub-rod 221 and the second sub-rod 222. The secondary rod 220 is rotatable about the main rod 210 to change the relative position of the support end 201. Or, as... Figure 3 and Figure 4 As shown, the secondary rod 220 may also include a first sub-rod 221 and a second sub-rod 222, the second sub-rod 222 being rotatable around the first sub-rod 221 to change the position of the support end 201.

[0079] There are several ways to connect the first sub-rod 221 and the second sub-rod 222, such as Figure 3 and Figure 4 As shown, the first sub-rod 221 and the second sub-rod 222 can be directly connected to each other. In other embodiments, the secondary rod 220 may also include other sub-rods connected between the first sub-rod 221 and the second sub-rod 222, and the second sub-rod 222 can be connected to the first sub-rod 221 through other sub-rods. There are also various ways in which the second sub-rod 222 can rotate relative to the first sub-rod 221. For example, the second sub-rod 222 is hinged to the first sub-rod 221, and the second sub-rod 222 itself can rotate relative to the first sub-rod 221. Alternatively, in other embodiments, the second sub-rod 222 can also rotate around the first sub-rod 221 through other sub-rods. This application illustrates this by exemplifying that the first sub-rod 221 and the second sub-rod 222 are directly connected to each other, and the second sub-rod 222 itself can directly rotate around the first sub-rod 221.

[0080] There are several ways in which the secondary rod 220 and the main rod 210 can rotate relative to each other. For example, the bracket 200 includes a connecting plate connected to the main rod 210. Both the connecting plate and the secondary rod 220 have through holes. A rotating shaft passes through the connecting plate and the rotating shaft to connect the main rod 210 and the secondary rod 220. The secondary rod 220 is rotatable around the rotating shaft. The axis of the rotating shaft intersects the axis of the main rod 210, for example, the axis of the rotating shaft is perpendicular to the axis of the main rod 210. That is, the secondary rod 220 can be hinged to the main rod 210. Optionally, the secondary rod 220 can be ball-jointed to the main rod 210 to increase the rotational freedom of the secondary rod 220.

[0081] There are several ways in which the second sub-rod 222 can rotate around the first sub-rod 221. For example, both the first sub-rod 221 and the second sub-rod 222 are provided with rotating holes, and a rotating shaft passes through the rotating holes on the first sub-rod 221 and the second sub-rod 222 to connect the first sub-rod 221 and the second sub-rod 222. The second sub-rod 222 can be rotatably arranged around the rotating shaft. That is, the second sub-rod 222 is hinged to the first sub-rod 221. Optionally, the second sub-rod 222 and the first sub-rod 221 can be connected by a ball joint to increase the rotational freedom of the second sub-rod 222.

[0082] Optionally, the lengths of the first sub-rod 221 and / or the second sub-rod 222 are variable to allow for more flexible adjustment of the position of the support end 201.

[0083] Optionally, the length of the secondary rod 220 is adjustable to allow for more flexible adjustment of the position of the support end 201.

[0084] Optionally, the second sub-rod 222 is movably configured along the first sub-rod 221 to adjust the length of the auxiliary rod 220.

[0085] There are various ways to connect the multiple auxiliary rods 220 and the main rod 210. For example, the ends of the multiple auxiliary rods 220 can surround the main rod 210 and be connected to the periphery of the main rod 210.

[0086] In some other alternative embodiments, such as Figure 8 As shown, the bracket 200 also includes a connecting ring 230, which is sleeved on the main rod 210. At least one secondary rod 220 is connected to the main rod 210 through the connecting ring 230, and the connecting ring 230 is movably disposed along the main rod 210.

[0087] In these alternative embodiments, at least one secondary rod 220 is connected to the main rod 210 via a connecting ring 230 sleeved on the main rod 210. The connecting ring 230 is movable along the main rod 210, so that at least one secondary rod 220 is movably arranged along the main rod 210 via the connecting ring 230 to adjust the position of the support end 201.

[0088] Optionally, the multiple auxiliary rods 220 may include a central auxiliary rod and two or more other auxiliary rods. The central auxiliary rod and the main rod 210 are coaxially arranged. The central auxiliary rod can be directly connected to the end face of the main rod 210 away from the base 100. The other auxiliary rods can be connected to the main rod 210 through the connecting ring 230. The central auxiliary rod can be used to support the center position of the flexible support platform 300.

[0089] Optionally, at least one secondary rod 220 is ball-hinged to the connecting ring 230 to increase the rotational freedom of the secondary rod 220.

[0090] Optionally, the main rod 210 is provided with a plurality of first limiting parts distributed at intervals along its length direction, and the connecting ring 230 is provided with a second limiting part on the surface facing the main rod 210. The first limiting parts and the second limiting parts cooperate with each other to limit the position of the connecting ring 230 and the main rod 210.

[0091] In these embodiments, the connecting ring 230 can be limited to a specified position by the first limiting part and the second limiting part, thereby limiting the auxiliary rod 220 connected to the connecting ring 230 to a specified position.

[0092] There are several ways to configure the first and second limiting parts. For example, the first limiting part can be a protrusion, and the second limiting part can be a groove, with the position of the connecting ring 230 limited by the mutual cooperation of the protrusion and the groove. Alternatively, the first limiting part can be a groove, and the second limiting part can be a protrusion.

[0093] There are several ways to set up the flexible support platform 300. The flexible support platform 300 can be made of flexible materials such as silicone, giving it good deformability. Alternatively, it can be made of other elastic materials with deformability, as long as the flexible support platform 300 has a certain degree of flexibility and the surface of the flexible support platform 300 used to support the flexible screen 20 can deform.

[0094] like Figure 7 As shown, the flexible support platform 300 can be installed as a single unit. Alternatively, as... Figure 5 and Figure 6 As shown, in other embodiments, the flexible support platform 300 includes a first support layer 301 and a second support layer 302. The first support layer 301 is connected to the bracket 200, and the second support layer 302 is located on the side of the first support layer 301 away from the bracket 200. The second support layer 302 includes a deformable wall portion 310 and a receiving cavity 320 formed by the wall portion 310.

[0095] In these optional embodiments, the flexible support platform 300 is divided into a first support layer 301 and a second support layer 302. The bracket 200 is connected to the first support layer 301, and the second support layer 302 is located on the side of the first support layer 301 opposite to the bracket 200. The second support layer 302 includes a receiving cavity 320 and a first medium 330 and a second medium 340 located within the receiving cavity 320. The bracket 200 is not directly connected to the second support layer 302. The bracket 200 is connected to the second support through the first support layer 301. This can improve the problems such as damage caused by stress concentration on the second support layer 302 when the bracket 200 is directly connected to the second support layer 302, ensure the sealing performance of the receiving cavity 320, and improve the problem of easy leakage of the first medium 330 and the second medium 340 from the receiving cavity 320.

[0096] Optionally, at least a portion of the outer surface of the second support layer 302 is adhesive, or at least a portion of the outer surface of the second support layer 302 is provided with an adhesive layer. This facilitates the adhesion of the second support layer 302 to the first support layer 301 and the flexible screen 20, thereby improving the stability of the relative positions of the second support layer 302, the first support layer 301, and the flexible screen 20.

[0097] Optionally, the support surface 350 is located on the side of the second support layer 302 away from the first support layer 301, so that the flexible screen 20 and the first support layer 301 can be respectively disposed on both sides of the second support layer 302.

[0098] Optionally, the material of the first support layer 301 and / or the second support layer 302 includes an elastic material, such as silicone, so that the first support layer 301 and / or the second support layer 302 have good deformability.

[0099] Optionally, the elastic modulus of the first support layer 301 is greater than that of the second support layer 302. That is, under the same phase transformation, the stress required by the first support layer 301 is greater than that required by the second support layer 302, and the structural stiffness of the first support layer 301 is greater than that of the second support layer 302, making the first support layer 301 less prone to damage and providing good protection for the second support layer 302.

[0100] The materials of the first support layer 301 and the second support layer 302 can be the same or different. When the materials of the first support layer 301 and the second support layer 302 are the same, the elastic modulus of the first support layer 301 can be made greater than that of the second support layer 302 by changing the proportion of each material in the first support layer 301.

[0101] The second aspect of this application also provides a bonding device for bonding a curved cover plate 10 and a flexible screen 20. The bonding device includes the support member provided in any of the first aspect embodiments. Since the bonding device provided in this application includes the aforementioned support member, the bonding device of this application has the beneficial effects of the aforementioned support member, which will not be elaborated further here.

[0102] Please refer to the diagram as well. Figure 9 , Figure 9 An embodiment of the third aspect of this application also provides a bonding method for bonding a flexible screen 20 and a curved cover plate 10. The bonding method can use the support member of any of the embodiments of the first aspect described above. The bonding method includes:

[0103] Step S01: Set the flexible support platform 300 to the first state and place the flexible screen 20 on the support surface 350 of the flexible support platform 300.

[0104] Optionally, as described above, when the flexible support platform 300 includes a receiving cavity 320 and a first medium 330 and a second medium 340 located within the receiving cavity, in a first state, the first medium 330 can be positioned close to the center of the flexible support platform 300, and the second medium 340 can be located around the periphery of the first medium 330. Optionally, the first state can be a flattened state. When the support 200 includes multiple support ends 201, the flexible support platform 300 can be in a flattened state by adjusting the relative positions of the multiple support ends 201. When the support surface 350 is circular, the first medium 330 can be adjusted to be positioned close to the center of the support surface 350, and the second medium 340 can be located around the periphery of the first medium 330. That is, when the first medium 330 includes air and the second medium 340 includes liquid, the gas is adjusted to be positioned at the center of the liquid, and the liquid surrounds the gas.

[0105] Step S02: The flexible support platform 300 bends and deforms and is in the second state.

[0106] Optionally, in step S02, the first medium 330 may be positioned at the bending apex of the flexible support platform 300 in a bent state.

[0107] As described above, when the bracket 200 includes multiple support ends 201, the flexible support platform 300 can be transformed from the first state to the second state by adjusting the relative positions of the support ends 201. For example, by rotating the secondary rod 220 relative to the main rod 210, rotating the second sub-rod 222 relative to the first sub-rod 221, or changing the length of the secondary rod 220, the multiple support ends 201 can be positioned on a curved surface, thereby causing the flexible support platform 300 to transform into a bent state.

[0108] Step S03: Make the flexible screen 20 fit with the curved cover plate 10 at the bending vertex of the flexible support platform 300, and continuously apply a force to the flexible support platform 300 towards the curved cover plate 10, so that the flexible screen 20 and the curved cover plate 10 gradually fit together.

[0109] Optionally, in step S03, the first medium 330 can be moved and the second medium 340 can be squeezed by the deformation of the wall 310, so that the flexible screen 20 and the curved cover plate 10 gradually fit together.

[0110] In the bonding method provided in this application embodiment, when the flexible support platform 300 is in a first state, such as a flattened state, the positions of the first medium 330 and the second medium 340 within the receiving cavity 320 are adjusted. After the second medium 340 is located around the first medium 330, the flexible screen 20 is then placed on the flexible support platform 300 to improve the influence of the flexible screen 20 on the positional observation of the first medium 330 and the second medium 340. Then, the flexible support platform 300 is placed in a second state, i.e., a bent state, with the first medium 330 located at the bending apex of the flexible support platform 300. When the flexible support platform 300 is moved to support the flexible screen 20 in bonding with the curved cover plate 10, the bending apex is relatively higher than other positions, and the bending apex first causes the flexible screen 20 to bond with the curved cover plate 10. After the flexible screen 20 and the curved cover plate 10 are bonded together at the bend apex, when the flexible support platform 300 is further squeezed, the wall 310 at the bend apex will deform. The first medium 330 deforms and squeezes the second medium 340 to its periphery, so that the flexible screen 20 and the curved cover plate 10 gradually bond together from the apex to the periphery of the apex, which can improve the bonding yield of the flexible screen 20 and the curved cover plate 10.

For example, the algorithm described in a particular embodiment may be modified without departing from the basic spirit of this application. Therefore, the present embodiments are to be regarded as exemplary rather than limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description, and all changes falling within the meaning and scope of the claims and their equivalents are thus included within the scope of this application.
