The plurality of adjustable components are spaced apart. The adjustable component includes a first end and a second end arranged oppositely. The first end is arranged on the base, and the second end is connected to the carrier table. The adjusting device is connected to the adjustable component through a first transmission mechanism. The rotation of the adjusting device can drive the second end to move through the first transmission mechanism to adjust the distance between the second end and the first end, so that the distances between the second ends and the first ends of at least two adjustable components are different, and the carrier table forms a preset curved surface.

[0008] In some embodiments, the number of adjusting devices is the same as the number of adjustable components, and the adjusting devices and the adjustable components are in one-to-one correspondence.

[0009] In some embodiments, the adjustable component includes a support rod and an adjusting rod. The adjusting rod is parallel to the support rod. The adjusting device is arranged on the support rod. The adjusting device is connected to the adjusting rod through a first transmission mechanism. The rotation of the adjusting device drives the adjusting rod to move in its axial direction through the first transmission mechanism to adjust the distance between the second end and the first end.

[0010] In some embodiments, the first transmission mechanism includes a gear and a rack arranged on the adjusting rod along the extending direction of the adjusting rod. The gear and the rack are meshed with each other. The adjusting device drives the gear to rotate so that the adjusting rod moves under the drive of the rack.

[0012] In some embodiments, the adjusting device is connected to at least two adjustable components through a first transmission mechanism, and the rotation of the adjusting device can drive the second ends of the at least two adjustable components to move different distances relative to the first ends.

[0013] In some embodiments, the adjustable component includes a second transmission mechanism and an adjusting rod, the second transmission mechanism is arranged on the base, the adjusting rod is connected to the second transmission mechanism, and one end of the adjusting rod far from the second transmission mechanism is connected to the stage;

[0014] The first transmission mechanism includes a transmission sub-mechanism and a first screw rod.

[0015] In some embodiments,

[0016] The adjusting rod includes a second screw rod, and the pitches of the second screw rods in at least two adjustable components are different; and / or,

[0017] The transmission ratios of the second transmission mechanisms in at least two adjustable components are different.

[0018] In some embodiments, the first screw rod includes a plurality of screw rod portions arranged along the extending direction, the screw rod portions are in transmission connection with the corresponding second transmission mechanisms, and the pitches of the screw rod portions corresponding to at least two adjustable components are different.

[0019] In some embodiments, the adjusting device is located in the middle of the first screw rod, and at least two adjustable components are arranged on opposite sides of the adjusting device along the extending direction of the first screw rod.

[0020] In some embodiments, the adjusting device has an origin position. When the adjusting device is in the origin position, the stage forms a plane;

[0021] The adjusting device can rotate clockwise or counterclockwise relative to the origin position. The clockwise rotation of the adjusting device relative to the origin position causes the stage to form a preset curved surface bent in a first direction, and the counterclockwise rotation of the adjusting device relative to the origin position causes the stage to form a preset curved surface bent in a second direction, and the first direction and the second direction are opposite.

[0022] In some embodiments, on the same side of the adjusting device, the distances between the second ends and the first ends of two adjacent adjustable components are different.

The second end of the adjustable component is connected to the connecting piece through a movable mechanism.

[0026] In some embodiments, the shape of the receiving groove is flat. The receiving groove is provided with an opening. The area of the connecting piece is larger than the area of the opening. The movable mechanism passes through the opening. During the movement of the second end, the second end drives the connecting piece to float in the receiving groove through the movable mechanism, so that the stage deforms towards the preset curved surface.

[0027] In some embodiments, the stage is used to carry a display panel, and the curvature of the preset curved surface formed by the stage is the same as the preset curvature of the display panel.

[0028] The technical solution of the embodiments of the present disclosure, the fixture structure of the present disclosure, adjusts the distance between the second end and the first end by rotating the adjusting device. Thus, by controlling the rotation angle and / or rotation direction of the adjusting device, the distance between the second end and the first end can be increased or decreased, and different distances between the second end and the first end can be controlled. Furthermore, the stage can form a convex preset curved surface, a concave preset curved surface, and curved surfaces with different curvatures. Therefore, when the fixture structure of the present disclosure is applied to the curved surface attachment process, both positive attachment (the curved surface is a convex curved surface) and negative attachment (the curved surface is a concave curved surface) can be realized, and the attachment process requirements for curved surfaces with different curvatures can be met.

[0044] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present disclosure, and different embodiments can be arbitrarily combined without conflict. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0045] Figure 1A It is a schematic diagram of the formation process of a curved display panel in a related technology. The liquid crystal display device includes a backlight module and a display panel module, and the display panel module is located on the light-emitting side of the backlight module. In a curved liquid crystal display device, the backlight module is fixed to form a curved surface, as Figure 1A shown. The display panel module includes a display panel and polarizers located on both sides of the display panel. Usually, the polarizers are attached to both sides of the display panel in a flat state, as Figure 1A shown. Thus, the display panel module adopts a flat structure. During assembly, the display panel module is fixed to the fixing studs of the curved backlight module through fixing lugs or tapes, so that the display panel module is forced to bend to form a curved surface. After the display panel module is forced to bend, the material stress causes the display panel module to be subjected to shear stress, resulting in light leakage and warping abnormalities, reducing the display quality of the product.

[0046] Figure 1B It is a schematic diagram of the bending directions of the polarizers on both sides of a curved display panel in a related technology. In the related technology, curved attachment can improve light leakage and warping abnormalities. However, since the curvatures of the polarizers 11 and 12 on both sides of the display panel 10 are different, as Figure 1B shown, the first polarizer 11 on the upper side and the second polarizer 12 on the lower side, one is bent forward and the other is bent backward. If the curved attachment of the first polarizer 11 and the second polarizer 12 is to be achieved, two sets of attachment jigs with different curvature directions are required to complete. Moreover, if the product curvature changes, the jig needs to be redesigned to meet the attachment requirements of products with different curvatures.

[0047] In order to achieve the curved attachment of the display product, the embodiments of the present disclosure provide a jig structure.

[0048] Figure 2is a schematic diagram of a fixture structure in an embodiment of the present disclosure, Figure 3 FIG. 1 is a schematic diagram of a fixture structure in another embodiment of the present disclosure. Figure 2 and Figure 3 As shown, the fixture structure includes a carrier 20, a base 30 and an adjustable module 40. The base 30 is located on one side of the carrier 20. For example, the carrier 20 can carry a display panel, and the carrier 20 can include a carrying surface 21, and the carrying surface 21 can contact the display panel. The base 30 can be located on the side of the carrier 20 away from the carrying surface 21.

[0049] The adjustable module 40 is located on the side of the carrier 20 facing the base 30. The adjustable module 40 includes a plurality of adjustable components 41 and at least one adjusting device 42. The plurality of adjustable components 41 are spaced apart, and the adjustable components 41 include a first end 41a and a second end 41b that are arranged opposite to each other, and the first end 41a is arranged on the base 30. The first end 41a can be fixedly arranged on the base 30. The second end 41b is connected to the carrier 20.

[0050] The adjusting device 42 is connected to the adjustable component 41 through the first transmission mechanism 43. The rotation of the adjusting device 42 can drive the second end 41b to move through the first transmission mechanism 43 to adjust the distance between the second end 41b and the first end 41a, so that the distance between the second end 41b and the first end 41a of at least two adjustable components 41 is different, and the carrier 20 presents a preset curved surface. Exemplarily, the adjusting device 42 is manually rotated to rotate the adjusting device 42. The rotation of the adjusting device 42 can drive the second end 41b to move relative to the first end 41a through the first transmission mechanism 43 to adjust the distance between the second end 41b and the first end 41a. By setting a suitable rotation angle of the adjusting device 42, the distances between the second ends 41b and the first ends 41a of the plurality of adjustable components 41 can be different from each other, so that the carrier 20 connected to the second ends 41b of the plurality of adjustable components 41 forms a preset curved surface under the action of the plurality of adjustable components 41.

[0051] The jig structure of the present disclosure adjusts the distance between the second end 41b and the first end 41a by rotating the adjusting device 42. Thus, by controlling the rotation angle and / or rotation direction of the adjusting device 42, the distance between the second end 41b and the first end 41a can be increased or decreased, and the distances between the second end 41b and the first end 41a in different adjustable components 41 can be controlled to be different. Furthermore, the stage 20 can form a convex preset curved surface, a concave preset curved surface, and curved surfaces with different curvatures. Therefore, when the jig structure of the present disclosure is applied to the curved surface attachment process, both positive attachment (the curved surface is a convex curved surface) and negative attachment (the curved surface is a concave curved surface) can be achieved, and the attachment process requirements for curved surfaces with different curvatures can be satisfied. There is no need to set multiple different jigs according to the curvature size and direction of the curved surface display product, saving the jig cost.

[0052] Exemplarily, in the jig structure, the stage 20 is disposed above the base 30, the adjustable component 41 is disposed in the vertical direction, the first end 41a of the adjustable component 41 is the lower end, the second end 41b of the adjustable component 41 is the upper end, the lower end of the adjustable component 41 is disposed on the base 30, and the upper end of the adjustable component 41 is connected to the stage 20.

[0053] The material and thickness of the stage 20 can be set as needed, as long as the stage 20 can form a curved surface. For example, the material of the stage 20 can include acrylic, and by setting the thickness of the stage 20, the acrylic stage 20 can be flexibly bent.

[0054] The shape of the base 30 can be set as needed. For example, in Figure 2 the example, the base 30 can be set as a flat plate shape, and in Figure 3 the example, the base 30 can be set as a vertical plate shape. The shape of the base 30 should facilitate the installation of the adjustable module 40.

[0055] In one embodiment, as Figure 2 shown, the number of the adjusting devices 42 can be the same as the number of the adjustable components 41, and the adjusting devices 42 and the adjustable components 41 are in one-to-one correspondence. The adjusting device 42 and the corresponding adjustable component 41 are connected by a first transmission mechanism 43. The rotation of the adjusting device 42 drives the second end 41b of the corresponding adjustable component 41 to move through the first transmission mechanism 43 to adjust the distance between the second end 41b and the first end 41a. In Figure 2 it, the upper end of the adjustable component 41 can be the second end 41b, and the lower end of the adjustable component 41 can be the first end 41a. By rotating the adjusting device 42, the distance between the upper end and the lower end of the adjustable component 41 can be adjusted, so that the stage 20 forms a preset curved surface.

[0056] Figure 4A is Figure 2 a schematic view of a partial cross-section of the fixture structure shown Figure 4B is Figure 4A a schematic cross-sectional view of the adjusting rod in Figure 5 is Figure 2 a partial schematic view of the fixture structure shown Figure 4A and Figure 5 show one of the adjusting devices 42 and the adjustable component 41 therein. As Figure 4A shown, the adjustable component 41 includes a support rod 411 and an adjusting rod 412, and the adjusting rod 412 is parallel to the support rod 411. The adjusting device 42 is disposed on the support rod 411, and the adjusting device 42 is connected to the adjusting rod 412 through a first transmission mechanism 43. The rotation of the adjusting device 42 drives the adjusting rod 412 to move in the extending direction of the adjusting rod 412 through the first transmission mechanism 43 to adjust the distance between the second end 41b and the first end 41a.

[0057] Exemplarily, the lower end of the support rod 411 may be the first end 41a, and the first end 41a is fixed on the base 30. The upper end of the adjusting rod 412 may be the second end 41b. When the rotation of the adjusting device 42 causes the adjusting rod 412 to move in the extending direction of the adjusting rod 412, the distance between the second end 41b and the first end 41a is adjusted, so as to adjust the position of the portion of the carrier 20 connected to the second end 41b, so that the carrier 20 forms a preset curved surface.

[0058] The first transmission mechanism 43 may include a gear 431 and a rack 432, and the gear 431 meshes with the rack 432. The rack 432 is disposed on the adjusting rod 412 along the extending direction of the adjusting rod 412, as Figure 4A shown. The adjusting device 42 can drive the gear 431 to rotate, and the adjusting device 42 drives the gear 431 to rotate so that the adjusting rod 412 moves under the drive of the rack 432. The rack 432 may be fixed on the adjusting rod 412, or the structure of the rack 432 may be formed on the side wall of the adjusting rod 412. Such a first transmission mechanism 43 has a simple structure, is convenient for installation, and can save costs.

[0059] Exemplarily, as Figure 4A shown, a first cavity may be provided inside the support rod 411 along its extending direction. A second cavity may be provided inside the adjusting rod 412 along its extending direction. The adjusting rod 412 is inserted into the first cavity. The rack 432 is disposed on the side wall of the second cavity, and the gear 431 is located in the second cavity and meshes with the rack 432. As Figure 5As shown, the adjusting device 42 can be located outside the support rod 411, and the adjusting device 42 is fixedly connected to the gear 431. In this way, the structure is simple and easy to implement, reducing the assembly difficulty; the adjusting device 42 is located outside the support rod 411, which facilitates driving the adjusting device 42 to rotate. For example, manually rotating the adjusting device 42 makes the adjustment more convenient, which is conducive to conveniently adjusting the preset curved surface; moreover, by arranging the gear 431 and the rack 432 inside the second cavity, the first transmission mechanism 43 is well hidden, enhancing the aesthetic appearance of the product.

[0060] As Figure 5 shown, the adjusting device 42 can include an adjusting knob 421, and the adjusting knob 421 is fixedly connected to the gear 431. By rotating the adjusting knob 421, the gear 431 can be rotated. The gear 431 can rotate synchronously with the adjusting knob 421. The adjusting knob 421 can be rotated in the clockwise direction or the counterclockwise direction.

[0061] For example, a shaft hole is provided on the support rod 411, and the adjusting device 42 further includes a connecting shaft. The connecting shaft passes through the shaft hole, and the adjusting knob 421 and the gear 431 are connected by the connecting shaft. Thus, the gear 431 can rotate synchronously with the adjusting knob 421. As Figure 5 shown, the adjusting device 42 can further include a scale disk 422. The scale disk 422 is arranged on the connecting shaft, and the scale disk 422 can rotate synchronously with the adjusting knob 421. The scale on the scale disk 422 is used to indicate the distance that the second end 41b moves upward or downward from the origin. The scale on the scale disk 422 corresponds to the rotation angle of the adjusting knob 421. When rotating the adjusting knob 421, the distance that the second end 41b moves upward or downward relative to the origin can be known through the scale on the scale disk 422.

[0062] As Figure 4B shown, a slide rail 4121 can be arranged on the inner side wall of the adjusting rod 412, and the slide rail 4121 can be a chute structure. One end of the gear 431 can be connected to the adjusting knob 421 by a connecting shaft, and the other end of the gear 431 can be embedded in the chute to ensure the stability of the gear 431 during rotation.

[0063] In the fixture structure of the embodiment of the present disclosure, when the distance between the second end 41b and the first end 41a in each adjustable component is the same, the carrier 20 forms a plane. In the fixture structure of the present disclosure, referring to Figure 4A and Figure 5 , the adjusting knob 421 and the second end 41b can both be set to the origin position. When the adjusting knob 421 is at the origin position, the second end 41b of the corresponding adjustable component 41 is also at its origin position. When the second ends 41b in each adjustable component are all at the origin position, the carrier 20 forms a plane.

[0064] Figure 6 Figure (A) is Figure 5 a schematic diagram of an adjustment process of an adjustable component in the shown structure, Figure 6 Figure (B) is Figure 5 another schematic diagram of an adjustment process of an adjustable component in the shown structure, Figure 7 is Figure 2 another state schematic diagram of the shown fixture structure. Referring to Figure 6 , by rotating the adjustment knob 421 clockwise or counterclockwise, the second end 41b can move downward or upward relative to the origin. By rotating the adjustment device 42 clockwise or counterclockwise, an appropriate distance can be provided between the second end 41b and the first end 41a of each adjustable component 41, so that the stage 20 forms a preset curved surface that protrudes as shown in Figure 7 or a preset curved surface that depresses as shown in Figure 2 .

[0065] In this article, the preset curved surface that protrudes can be understood as one of the preset curved surfaces bent in the first direction and the preset curved surface bent in the second direction, and the preset curved surface that depresses can be understood as the other of the preset curved surfaces bent in the first direction and the preset curved surface bent in the second direction, where the second direction is opposite to the first direction. Or, the preset curved surface bent in the first direction is one of the preset curved surface that protrudes and the preset curved surface that depresses, and the preset curved surface bent in the second direction is the other of the preset curved surface that protrudes and the preset curved surface that depresses.

[0066] Figure 4A and Figure 5 show a structure of the first transmission mechanism 43. It should be noted that the first transmission mechanism 43 is not limited to the transmission mechanism of the gear 431 and the rack 432, and other transmission mechanisms can also be used. For example, for the first transmission mechanism 43, the first bevel gear 431, the second bevel gear 431, and the adjusting rod 412 can use an adjusting screw. The second bevel gear 431 meshes with the first bevel gear 431. The rotation of the adjustment device 42 can drive the first bevel gear 431 to rotate. The rotation of the first bevel gear 431 can drive the second bevel gear 431 to rotate. The rotation of the second bevel gear 431 can drive the adjusting screw to move up and down, thereby adjusting the distance between the second end 41b and the first end 41a. Or, the first transmission mechanism 43 can include a worm and worm gear mechanism, etc.

[0067] In another embodiment, as shown in Figure 3 , the adjustment device 42 is connected to at least two adjustable components 41 through the first transmission mechanism 43. The first transmission mechanism 43 is configured to drive the second ends 41b of at least two adjustable components 41 to move different distances relative to the first ends 41a as the adjustment device 42 rotates. Thus, different distances are provided between the second ends 41b and the first ends 41a of at least two adjustable components 41.

[0068] For such a fixture structure, the adjusting device 42 is connected to at least two adjustable components 41 through the first transmission mechanism 43 to adjust the distance between the second end 41b and the first end 41a of the at least two adjustable components 41. Thus, the number of adjusting devices 42 is less than the number of adjustable components 41, reducing the cost of the adjustable module 40. Moreover, at least two adjustable components 41 can be adjusted by one adjusting device 42, saving the adjustment time and improving the adjustment efficiency of the fixture structure.

[0069] As Figure 3 shown, the adjustable component 41 includes a second transmission mechanism 413 and an adjusting rod 412. The second transmission mechanism 413 is disposed on the base 30. The adjusting rod 412 is connected to the second transmission mechanism 413, and the end of the adjusting rod 412 away from the second transmission mechanism 413 is connected to the carrier 20. In Figure 3 , the upper end of the adjusting rod 412 is the end of the adjusting rod 412 away from the second transmission mechanism 413, and the second end 41b can be the upper end of the adjusting rod 412; the second transmission mechanism 413 is fixed on the base 30, and the position where the second transmission mechanism 413 is fixed on the base 30 can be understood as the first end 41a. The adjustable component 41 may further include a housing, and the second transmission mechanism 413 may be located inside the housing, and the housing is fixed on the base 30.

[0070] The first transmission mechanism 43 may include a transmission sub-mechanism 433 and a first screw 434. The adjusting device 42 is in transmission connection with the first screw 434 through the transmission sub-mechanism 433, and the first screw 434 is in transmission connection with the second transmission mechanism 413. The extending direction of the first screw 434 is perpendicular to the rotation axis direction of the adjusting device 42. The extending direction of the first screw 434 is perpendicular to the extending direction of the adjusting rod 412, and the extending direction of the adjusting rod 412 is perpendicular to the rotation axis direction of the adjusting device 42.

[0071] The rotation of the adjusting device 42 can drive the first screw 434 to rotate through the transmission sub-mechanism 433. The rotation of the first screw 434 can drive the second end 41b to move along the axial direction (or extending direction) of the adjusting rod 412 through the second transmission mechanism 413 to adjust the distance between the second end 41b and the first end 41a.

[0072] For such a structure, a plurality of adjustable components 41 can be arranged along the extending direction of the first screw 434, and the second transmission mechanism 413 of each adjustable component 41 is in transmission connection with the first screw 434 at the corresponding position. When the first screw 434 rotates under the drive of the rotation of the adjusting device 42, the second transmission mechanism 413 of each adjustable component 41 drives the corresponding second end 41b to move, thereby adjusting the distance between the second end 41b and the first end 41a in each adjustable component 41.

[0073] In one embodiment, the adjusting rod 412 may include a second screw rod, such that the second screw rod is in driving connection with the second transmission mechanism 413. Meanwhile, the upper end of the second screw rod is connected to the stage 20. The second transmission mechanism 413 may adopt a transmission mechanism with a commutation function to convert the rotation direction of the first screw rod 434 into the rotation direction of the second screw rod, and drive the upper end of the second screw rod to move along the extension direction of the second screw rod.

[0074] The pitches of the second screw rods in at least two adjustable assemblies 41 are different, so that the distances by which the upper ends of the second screw rods in the corresponding two adjustable assemblies 41 move driven by the rotation of the first screw rod 434 are different. By reasonably setting the pitches of the second screw rods in the adjustable assemblies 41 along the extension direction of the first screw rod 434, the movement of each second screw rod along the extension direction of the first screw rod 434 can drive the stage 20 to deform, so that the stage 20 forms a preset curved surface.

[0075] Exemplarily, on the same side of the adjusting device 42, the distances between the second ends 41b and the first ends 41a of two adjacent adjustable assemblies 41 are different. As Figure 3 shown, in the adjustable module 40, along the extension direction of the first screw rod 434, the pitches of the second screw rods in multiple adjustable assemblies 41 located on the same side of the adjusting device 42 are different from each other. Thus, the rotation of the adjusting device 42 can cause the stage 20 located on the same side of the adjusting device 42 to form a curved surface.

[0076] In the adjustable module 40, along the extension direction of the first screw rod 434, the adjustable assemblies 41 on both sides of the adjusting device 42 may be symmetrically arranged, so that the rotation of the adjusting device 42 can cause the stage 20 to form a preset curved surface that is symmetric with respect to the rotation axis direction of the adjusting device 42. For example, Figure 3 the stage 20 forms a left - right symmetric preset curved surface.

[0077] In one embodiment, referring to Figure 3 , the first screw rod 434 may include a plurality of screw rod portions arranged along the extension direction, and the screw rod portions are in driving connection with the corresponding second transmission mechanisms 413. Each screw rod portion corresponds to an adjustable assembly 41, and the screw rod portion is in driving connection with the second transmission mechanism 413 of the corresponding adjustable assembly 41. The pitches of the screw rod portions corresponding to at least two adjustable assemblies 41 are different. Thus, when the first screw rod 434 rotates, the distances transmitted to the corresponding second transmission mechanisms 413 by each screw rod portion are different, and further, the distances by which the second transmission mechanisms 413 drive the upper ends of the second screw rods to move are different. By reasonably setting the pitches of the respective screw rod portions along the extension direction of the first screw rod 434, the movement of each second screw rod along the extension direction of the first screw rod 434 can drive the stage 20 to deform, so that the stage 20 forms a preset curved surface.

[0078] Exemplarily, on the same side of the adjusting device 42, the distances between the second ends 41b and the first ends 41a of two adjacent adjustable components 41 are different. Refer to Figure 3 , in the adjustable module 40, in the extending direction of the first screw 434, the pitches of the screw portions corresponding to a plurality of adjustable components 41 located on the same side of the adjusting device 42 are different from each other. Thus, the rotation of the adjusting device 42 can cause the stage 20 located on the same side of the adjusting device 42 to form a curved surface.

[0079] In the adjustable module 40, in the extending direction of the first screw 434, the screw portions of the first screw 434 on both sides of the adjusting device 42 can be symmetrically arranged. Thus, the rotation of the adjusting device 42 can cause the stage 20 to form a preset curved surface that is symmetric with respect to the rotation axis direction of the adjusting device 42.

[0080] In the above embodiment, by setting the pitches of the screw portions to be different and / or the pitch of the second screw to be different, the moving distances of the second ends 41b of different adjustable components 41 are made different. In other embodiments, the transmission ratios of the second transmission mechanisms 413 in at least two adjustable components 41 can also be set to be different to make the moving distances of the second ends 41b of different adjustable components 41 different. For example, in Figure 3 , on the same side of the adjusting device 42, the transmission ratios of the second transmission mechanisms 413 in two adjacent adjustable components 41 are different. Thus, when the rotation of the first screw 434 drives the second end 41b to move through the second transmission mechanism 413, the moving distances of the second ends 41b in two adjacent adjustable components 41 are different.

[0081] Figure 3 In the illustrated embodiment, the stage 20 forms a recessed preset curved surface. By changing the rotation direction of the adjusting device 42, the stage 20 can be caused to form a convex preset curved surface.

[0082] As Figure 3 shown, the adjusting device 42 can be located in the middle of the first screw 434, and a plurality of adjustable components 41 can be arranged on opposite sides of the adjusting device 42 along the extending direction of the first screw 434. The plurality of adjustable components 41 located on opposite sides of the adjusting device 42 can be symmetrically arranged.

[0083] Refer to Figure 3, the adjusting device 42 can have an origin position. When the adjusting device 42 is in the origin position, the stage 20 forms a plane. The adjusting device 42 can rotate clockwise or counterclockwise relative to the origin position. The clockwise rotation of the adjusting device 42 relative to the origin position can cause the stage 20 to form a preset curved surface that bends in a first direction; the counterclockwise rotation of the adjusting device 42 relative to the origin position can cause the stage 20 to form a preset curved surface that bends in a second direction, and the first direction is opposite to the second direction.

[0084] The preset curved surface that bends in the first direction is one of a convex preset curved surface and a concave preset curved surface, and the preset curved surface that bends in the second direction is the other of a convex preset curved surface and a concave preset curved surface.

[0085] Generally, the curved display panel bends in one direction and does not bend in the other direction. In one embodiment, the number of adjustable modules 40 is at least two sets. At least two sets of adjustable modules 40 are spaced apart along the width direction of the stage 20, and multiple adjustable components 41 in the adjustable module 40 are spaced apart along the length direction of the stage 20. The length direction of the stage 20 is the deformation direction of the stage 20. For example, Figure 3 in, the length direction of the stage 20 is the extending direction of the first screw 434. The width direction of the stage 20 is the non-deformable direction of the stage 20, and the width direction of the stage 20 is perpendicular to the length direction of the stage 20. For example, Figure 3 in, the width direction of the stage 20 is the front-back direction.

[0086] For example, the curved display panel is usually curved in the length direction and does not bend in the width direction. Therefore, at least two sets of adjustable modules 40 can be spaced apart along the width direction of the display panel, and multiple adjustable components 41 in the adjustable module 40 can be spaced apart along the length direction of the display panel. Thus, when the display panel is placed on the stage 20, the length direction of the display panel is set along the length direction of the stage 20, and the width direction of the display panel is set along the width direction of the stage 20.

[0087] In Figure 3 the embodiment, when the number of adjustable modules 40 is at least two sets, the adjusting devices 42 in at least two sets of adjustable modules 40 can be connected into an integral structure through a connecting shaft. Thus, when one of the adjusting devices 42 rotates, it can drive all the adjusting devices 42 to rotate synchronously, and the stage 20 can be driven to form a preset curved surface through one of the adjusting devices 42.

[0088] In actual implementation, the adjusting device 42 can be set to manual adjustment. For example, the adjusting device 42 includes an adjusting knob 421. By manually rotating the adjusting knob 421, the second end 41b of the adjustable component 41 can be driven to move relative to the first end 41a.

[0089] The fixture structure may further include a driving mechanism for driving the adjusting device 42 to rotate. Thus, the distance between the second end 41b and the first end 41a of the adjustable component 41 can be automatically adjusted, realizing the automation of the fixture structure and avoiding manual adjustment errors.

[0090] Figure 8 FIG. is a schematic diagram of the connection structure between the second end of the adjustable component and the stage in an embodiment of the present disclosure. In one embodiment, the second end 41b of the adjustable component 41 is connected to the stage 20 through a flexible connection mechanism 50. It can be understood that the stage 20 can be deformed. When the second end 41b of the adjustable component 41 rises or falls, the second end 41b applies a supporting force or a pulling force to the stage 20, which may cause abnormal deformation of the connection area of the stage 20 connected to the second end 41b. By setting the second end 41b of the adjustable component 41 to be connected to the stage 20 through the flexible connection mechanism 50, abnormal deformation of the connection area of the stage 20 caused by the movement of the second end 41b can be avoided, ensuring the smoothness of the preset curved surface formed by the stage 20.

[0091] Exemplarily, as Figure 8 shown, the flexible connection mechanism 50 includes a receiving groove 51 and a connecting piece 52. The receiving groove 51 is provided on the side of the stage 20 facing the adjustable component 41. For example, a thin wall can be provided on the side of the stage 20 facing the adjustable component 41, and a receiving groove 51 is formed between the thin wall and the stage 20. The material of the thin wall can be the same as that of the stage 20, and the thin wall can be pasted on the lower surface of the stage 20 to avoid deformation of the stage 20 caused by the thin wall. The thickness of the thin wall can be less than the thickness of the stage 20. The specific thickness of the thin wall can be set as needed.

[0092] The connecting piece 52 is located in the receiving groove 51, and the connecting piece 52 can float in the receiving groove 51. As Figure 5 shown, the groove height of the receiving groove 51 is greater than the thickness of the connecting piece 52. In the plane where the connecting piece 52 is located, the width of the receiving groove 51 is greater than the width of the connecting piece 52, and the length of the receiving groove 51 is greater than the width of the connecting piece 52. Thus, the connecting piece 52 can float in the receiving groove 51.

[0093] As Figure 8As shown, the second end 41b of the adjustable component 41 is connected to the connecting piece 52 through the movable mechanism 53. Generally, the second end 41b of the adjustable component 41 moves in the vertical direction, and the moving direction of the second end 41b cannot be changed. If the second end 41b of the adjustable component 41 is connected to the connecting piece 52 through a fixed structure, then, during the process of forming the preset curved surface on the carrier 20, the second end 41b of the adjustable component 41 will exert a vertical supporting force or pulling force on the connecting area, resulting in abnormal deformation of the connecting area of the carrier 20 (for example, a convex hull or a concave pit is formed in the connecting area), so that convex hulls or concave pits appear on the preset curved surface. The connecting area is the area of the carrier 20 connected to the second end 41b of the adjustable component 41, and the area of the connecting area is usually relatively small.

[0094] In this embodiment, the second end 41b of the adjustable component 41 is arranged to be connected to the connecting piece 52 through the movable mechanism 53. Thus, during the process of the second end 41b of the adjustable component 41 moving in the vertical direction, the state of the movable mechanism 53 can change with the deformation of the carrier 20. Furthermore, the direction of the supporting force or pulling force generated by the second end 41b of the adjustable component 41 on the movable mechanism 53 changes with the deformation of the carrier 20, avoiding the formation of convex hulls or concave pits in the connecting area of the carrier 20; and, by setting the connecting piece 52, the supporting force or pulling force generated by the second end 41b of the adjustable component 41 can be evenly dispersed, avoiding the concentration of force, further reducing the risk of forming convex hulls or concave pits in the connecting area, and ensuring the smoothness of the preset curved surface formed by the carrier 20.

[0095] Exemplarily, the movable mechanism 53 can include a hinge structure or a universal joint structure, etc. The movable mechanism 53 can move freely at least in the deformation direction of the carrier 20.

[0096] As Figure 8 shown, the shape of the receiving groove 51 can be flat. The receiving groove 51 is provided with an opening 54, and the area of the connecting piece 52 is larger than the area of the opening 54. The movable mechanism 53 passes through the opening 54 to connect the second end 41b with the connecting piece 52. During the movement of the second end 41b, the second end 41b drives the connecting piece 52 to float in the receiving groove 51 through the movable mechanism 53, so that the carrier 20 deforms towards the preset curved surface, and then the preset curved surface is formed.

[0097] Setting the area of the connecting piece 52 to be larger than the area of the opening 54 can prevent the connecting piece 52 from falling off during the deformation of the carrier 20. The size of the opening 54 can be set to be larger than the size of the movable mechanism 53. Thus, during the deformation of the carrier 20, the movable mechanism 53 can move freely in the opening 54 along with the floating of the connecting piece 52, realizing the deformation of the carrier 20.

[0098] In the fixture structure of the embodiments of the present disclosure, the carrier 20 can be used to carry the display panel. The curvature of the preset curved surface formed by the carrier 20 is the same as the preset curvature of the display panel.

[0099] The fixture structure of the present disclosure can be used in the process of attaching the polarizer. For example, when attaching the first polarizer, the adjusting device 42 can be used to make the carrier 20 form a convex preset curved surface, and then the display panel is placed on the carrier 20, and the display panel fits with the convex preset curved surface of the carrier 20; then the first polarizer is attached to the surface of the display panel. When attaching the second polarizer, the adjusting device 42 can be used to make the carrier 20 form a concave preset curved surface, and then the display panel is placed on the carrier 20, and the display panel fits with the concave preset curved surface of the carrier 20; then the second polarizer is attached to the surface of the display panel. In this way, during the attaching process, the polarizer is bent and deformed along with the attaching process, reducing the shear stress caused by forced bending of the polarizer and the display panel, resulting in light leakage and warping abnormalities, and improving the display quality of the display device.

[0100] In the fixture structure of the embodiments of the present disclosure, by adjusting the adjusting device 42, the carrier 20 can form curved surfaces with various curvatures, which can adapt to the attachment of polarizers with different curvatures.

[0101] The fixture structure of the embodiments of the present disclosure can also be applied in the display effect test. For example, by adjusting the adjusting device 42, the carrier 20 forms a curved surface with a preset curvature, the backlight module is arranged below the carrier 20, and the display panel is placed on the carrier 20, so that the display panel is bent into a preset curved surface, and the display effects of display panels with different curvatures can be observed, providing a reference for the design of the product. By using the fixture structure of the present disclosure, the display panel can be bent into curved surfaces with different curvatures, so that display panels with multiple curvature curved surfaces can be tested.
