[0035] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0036] In related technologies, such as Figure 1 As shown, the flexible screen 200 includes a first flexible screen 210 and a second flexible screen 220. The first flexible screen 210 (main screen) is circular. When the flexible screen 200 is in the unfolded state, the second flexible screen 220 (sub-screen) is fan-shaped. When the flexible screen 200 is in a three-dimensional state, the second flexible screen 220 is arranged around the outer periphery of the first flexible screen 210 and forms a three-dimensional structure with the first flexible screen 210.

[0037] Therefore, such as Figure 2 One embodiment of this application provides a guide film 100, which includes a first main body portion 110 and a second main body portion 120. The first main body portion 110 has at least a circular shape in a first state for attaching a first flexible screen 210. The second main body portion 120 has at least a fan-shaped shape in the first state for attaching a second flexible screen 220. The second main body portion 120 is located on the outer periphery of the first main body portion 110 and is integrally connected to the first main body portion 110. The first state is a planar state, and the second state is a non-planar state, for example, the second state is a three-dimensional state.

[0038] In the technical solution of this application embodiment, the guide film 100 includes a first main body portion 110 and a second main body portion 120. The first main body portion 110 is used to attach to the first flexible screen 210 of the flexible screen body 200, and the second main body portion 120 is located on the outer periphery of the first main body portion 110 and is used to attach to the second flexible screen 220 of the flexible screen body 200. In the technical solution of this application embodiment, the second main body portion 120 can be folded relative to the first main body portion 110 to drive the second flexible screen 220 and the first main body portion 110 to form a three-dimensional structure; the second main body portion 120 can drive the second flexible screen 220 to be disposed around the outer periphery of the first flexible screen 210, so that the flexible screen 200 and the cover plate 400 can be bonded, reducing bubbles generated during bonding and improving bonding yield.

[0039] In one embodiment of this application, the area of ​​the first main body 110 is equal to the area of ​​the first flexible screen 210. In other embodiments, the area of ​​the first main body 110 may be larger than the area of ​​the first flexible screen 210. In this embodiment of the application, the area of ​​the second main body 120 is larger than the area of ​​the second flexible screen 220.

[0040] In one embodiment of this application, the guide film 100 further includes a connecting portion 130, which connects the first main body portion 110 and the second main body portion 120. In this embodiment, by providing the connecting portion 130, the first main body portion 110 and the second main body portion 120 can be integrated, allowing the first main body portion 110 and the second main body portion 120 to move as a single unit, improving the linkage between the first main body portion 110 and the second main body portion 120, and enhancing the adhesion effect between the flexible screen 200 and the cover plate. In other embodiments, the connecting portion 130 may be omitted, and the first main body portion 110 and the second main body portion 120 may be a single integrated structure.

[0041] In one embodiment of this application, the guide film 100 further includes a disconnection region 140. The disconnection region 140 is located between the second main body portion 120 and the first main body portion 110, and is located on both sides of the connecting portion 130. The disconnection region 140 can reduce the stress around the second flexible screen 220 when it is attached to the first flexible screen 210, reduce the deformation of the second flexible screen 220 during the attachment process, thereby reducing the risk of wrinkles on the curved surface. This improves the bonding yield between the first flexible screen 210 and the second flexible screen 220.

[0042] In one embodiment of this application, as Figure 3 A plurality of first positioning holes 121 are provided on the second main body 120, and the first positioning holes 121 are located on the side of the first main body 110 away from the second main body 120. In this embodiment, the first positioning holes 121 are provided on the side away from the first main body 110 and are spaced apart along a fan-shaped ring. The first positioning holes 121 can play a positioning role, making it easier to determine the attachment position of the second main body 120, thereby determining the position of the second flexible screen 220 and providing alignment accuracy between the second flexible screen 220 and the cover plate. In other embodiments, the second main body 120 is not provided with first positioning holes 121, such as... Figure 2 By omitting the first positioning hole 121, the number of steps can be reduced, saving time and costs. In this embodiment, the plurality of first positioning holes 121 are not uniformly distributed on the outer periphery of the fan shape. In other embodiments, the plurality of first positioning holes 121 may also be uniformly distributed on the outer periphery of the fan shape.

[0043] In one embodiment of this application, as Figure 2 In the first state, the second main body portion 120 includes an opening segment 122 located on the outer periphery of the first main body portion 110; the guide membrane 100 includes at least one extension portion 150 disposed on the side of the first main body portion 110 near the opening segment 122. In this embodiment, the number of extension portions 150 is one. In another embodiment, such as... Figure 4As shown, the number of extensions 150 can also be three. In other embodiments, the number of extensions 150 can also be two or more. In this embodiment, the extension 150 is a columnar extension structure; in other embodiments, the extension 150 can be other shapes, including at least circular and triangular shapes. In this embodiment, the extension 150 is provided to facilitate the clamping device to hold the extension 150 so that the first main body 110 can support the flexible screen 200 and attach it to the support pad 520 during use (see...). Figure 6 )superior.

[0044] In one embodiment of this application, the extension 150 passes through the opening 122, such that the extension 150 is at least partially located outside the second main body 120. This facilitates the gripping of the extension 150 and allows the guide film 100 to be attached to the support pad 520 (see figure) during use. Figure 6 In this embodiment, the mutual interference between the first main body portion 110 and the second main body portion 120 is relatively small. In other embodiments, the extension portion 150 may not pass through the opening segment 122.

[0045] Continue as Figure 3 In one embodiment of this application, a second positioning hole 151 is provided on the extension portion 150. Specifically, in this embodiment, two second positioning holes 151 are provided on the extension portion 150, and the two second positioning holes 151 are spaced apart from one end near the first main body portion 110 to the end away from the first main body portion 110. The second positioning holes 151 can play a positioning role, making the attachment and positioning between the first main body portion 110 and the support pad 520 more accurate, and improving the bonding accuracy of the first flexible screen 210. In other embodiments, refer to Figure 2 The extension 150 does not have a second positioning hole 151, as shown in the reference. Figure 3 Alternatively, one or more second positioning holes 151 can be set.

[0046] In one embodiment of this application, the bonding support portion 160 is connected to the side of the first main body portion 110 opposite to the connecting portion 130. The bonding support portion 160 is used to support bonding circuitry, including flexible printed circuit boards (FPCs) or flip-chip films, etc. Figure 2 The binding support portion 160 is disposed between the first main body portion 110 and the extension portion 150. In other embodiments, the binding support portion 160 may be omitted, and the extension portion 150 may be directly connected to the first main body portion 110.

[0047] In one embodiment of this application, as Figure 9As shown, the guide film 100 includes a first film layer 171, a support layer 172, and a second film layer 173 in a direction perpendicular to the plane of the guide film 100. The support layer 172 is located between the first film layer 171 and the second film layer 173. The first film layer 171 is used to support the flexible screen 200, and the second film layer 173 is disposed on the side of the first film layer 171 away from the flexible screen 200. In this embodiment, at the connecting portion 130 (see...) Figure 2 In one embodiment, the first film layer 171 and the support layer 172 are not provided at the junction of the binding support portion 160 and the first main body portion 110, but a second film layer 173 is provided, so that the guide film 100 forms a first hollow portion 600 at the connection portion 130, thereby reducing the bending stress of the guide film 100. In another embodiment of this application, the first film layer 171 and the support layer 172 may also be omitted at the junction of the binding support portion 160 and the first main body portion 110, and a second film layer 173 may be provided, so that the guide film 100 forms a second hollow portion 610 at the junction, thereby reducing the bending stress of the guide film 100 at the junction of the binding support portion 160 and the first main body portion 110.

[0048] This application also includes a second technical solution, see below. Figure 5 A bonding device includes the aforementioned guide film 100, pressing mold 300, and supporting mold 500. The pressing mold 300 has a groove 310 for receiving a cover plate 400; the supporting mold 500 is used to mate with the cover plate 400; wherein, the supporting mold 500 includes a base 510 and a supporting pad 520, the side of the base 510 includes a frustum-shaped side, the side of the base 510 is used to mate with at least a portion of the second main body portion 120 of the guide film 100; the supporting pad 520 is disposed at the top of the base 510, the end face of the supporting pad 520 is circular, the end face of the supporting pad 520 is used to mate with at least a portion of the first main body portion 110 of the guide film 100.

[0049] In the technical solution of this application embodiment, the bonding device includes the guide film 100 of the above embodiment. The guide film 100 includes a first main body portion 110 and a second main body portion 120. The first main body portion 110 is used to attach to the first flexible screen 210 of the flexible screen body 200, and the second main body portion 120 is located on the outer periphery of the first main body portion 110 and is used to attach to the second flexible screen 220 of the flexible screen body 200. In the technical solution of this application embodiment, the first main body portion 110 can drive the first flexible screen 210 to attach to the upper surface of the support pad 520, and the second main body portion 120 can drive the second flexible screen 220 to attach to the side of the support pad 520. A portion of the second main body portion 120 can be attached to the side of the base 510, thereby achieving the function of fixing the first flexible screen 210 and the second flexible screen 220, so that the pressing mold 300 can drive the cover plate 400 to attach to the first flexible screen 210 and the second flexible screen 220. In this embodiment, the bonding device can better fix the flexible screen 200 onto the support mold 500 by providing the first main body 110 and the second main body 120 through the guide film 100, so that the flexible screen 200 and the cover plate can be bonded, reducing the air bubbles generated during bonding and improving the bonding yield.

[0050] In this embodiment, the base 510 is shaped like a frustum, causing its sides to unfold into a fan shape, facilitating attachment to a portion of the second main body 120. In other embodiments, the base 510 may also be cylindrical, and the unfolded shape of its sides may include a cube, a cuboid, etc. (See reference) Figure 5 In another embodiment, in the Y direction, the base 510 may include both a frustum and a cylinder structure, with the cylinder located on the side of the frustum facing away from the support pad 520. By providing the cylindrical structure, the height of the base 510 is increased, which facilitates the adjustment of the height of the support mold 500. In other embodiments, the cylinder may not be provided at the lower end of the frustum.

[0051] In this embodiment, the support mold 500 includes a support pad 520. The support pad 520 has high rigidity, which facilitates providing support to the guide film 100 and the flexible screen 200. At the same time, the surface of the support pad 520 is relatively soft, so when the guide film 100 guides the flexible screen 200 to adhere to the support mold 500, the damage to the surface of the guide film 100 is small or non-existent, reducing the damage caused by the bending of the second flexible screen 220. When the guide film 100 is bonded to the support mold 500, the first main body 110 of the guide film 100 is bonded to the upper part of the support pad 520 of the support mold 500 in the Y direction, and the second main body 120 of the guide film 100 is bonded to the side of the support pad 520 of the support mold 500. The side of the support pad 520 includes the side of a frustum. The first main body 110 and the second main body 120 are bonded to different planes of the support pad 520, so that the second main body 120 surrounds the first main body 110, reducing the probability of wrinkles in the second main body 120, improving the bonding effect when the guide film 100 is bonded to the support mold 500, and further improving the yield of bonding between the cover plate 400 and the flexible screen 200. In this embodiment, the base 510 and the support pad 520 are separate structures, and the base 510 and the support pad 520 are made of different materials. In other embodiments, the base 510 and the support pad 520 may also be an integral structure, and the base 510 and the support pad 520 may be made of the same material.

[0052] In this embodiment, a plurality of first positioning holes 121 are provided on the second main body portion 120, and the first positioning holes 121 are located on the side of the first main body portion 110 away from the second main body portion 120. The first positioning holes 121 are provided on the side away from the first main body portion 110, and are spaced apart along a fan-shaped ring. The extension portion 150 is provided with second positioning holes 151, which are spaced apart from the end near the first main body portion 110 to the end away from the first main body portion 110.

[0053] In one embodiment of this application, the support mold 500 includes a plurality of positioning posts 511 disposed on the side of the base 510. The positioning posts 511 are used to cooperate with the first positioning hole 121 and / or the second positioning hole 151. In this embodiment of the application, by providing positioning posts 511 on the side of the base 510, and by having the positioning posts 511 cooperate with the first positioning hole 121 and / or the second positioning hole 151, the positioning accuracy of the guide film 100 is improved, thereby facilitating the fixing and positioning of the first main body 110 and / or the second main body 120.

[0054] In one embodiment of this application, see [reference] Figure 8The support mold 500 includes a telescopic drive mechanism (not shown), which drives the positioning post 511 to extend to the side of the base 510 or retract into the base 510. Before the guide film 100 is attached, the telescopic drive mechanism drives the positioning post 511 to extend to the side of the base 510 to the outside, so that the positioning post 511 can cooperate with the first positioning hole 121 and / or the second positioning hole 151 of the guide film 100 to position and fix the guide film 100 to the support mold 500. After the cover plate 400 is attached to the flexible screen 200, the drive structure can drive the positioning post 511 to retract into the base 510, facilitating the removal of the guide film 100 from the support mold 500, so that the first positioning hole 121 and / or the second positioning hole 151 will not affect the removal of the guide film 100. In other embodiments, see Figure 7 Alternatively, a telescopic drive mechanism may not be required.

[0055] This application also includes a third technical solution, such as Figure 10 The aforementioned method for manufacturing a display device employs the bonding device described above.

[0056] The specific methods for manufacturing the display device include:

[0057] S11: Provides a flexible screen body 200.

[0058] In this embodiment, the flexible screen 200 includes a first flexible screen 210 and a second flexible screen 220, with the second flexible screen 220 disposed on the outer periphery of the first flexible screen 210. The first flexible screen 210 is circular; when the flexible screen 200 is in the unfolded state, the second flexible screen 220 is fan-shaped. The first flexible screen 210 and the second flexible screen 220 are connected as a single unit.

[0059] S12: One side of the flexible screen 200 is attached to the guide film 100, and the first flexible screen 210 is attached to the first main body 110 of the guide film 100, and the second flexible screen 220 is attached to the second main body 120 of the guide film 100.

[0060] In one embodiment of this application, the flexible screen 200 is attached to the guide film 100 via an adhesive layer.

[0061] In other embodiments, the guide film 100 may also be a single unit where the first main body 110 and the second main body 120 are integrally connected, with redundant membrane structures on the exterior of the first main body 110 and the second main body 120. The flexible screen 200 is then entirely attached to the guide film 100.

[0062] In one embodiment of this application, the guide film 100 sequentially includes a first film layer, a support layer, and a second film layer in a direction perpendicular to the plane of the guide film 100; the support layer is located between the first film layer and the second film layer; the first film layer is used to support the flexible screen 200; and the second film layer is disposed on the side of the first film layer away from the flexible screen 200. In this embodiment of the application, the first film layer and the support layer are not disposed at the connection portion 130, but the second film layer is disposed, so that the guide film 100 forms a first hollow portion 600 at the connection portion 130, thereby reducing the bending stress of the guide film 100.

[0063] In this embodiment, a polarizer (not shown) can be attached to the flexible screen 200; the flexible screen 200 with the attached polarizer is then bound to external circuits such as a flexible circuit board and a flip-chip film; an optical adhesive layer (not shown) is placed on the side of the polarizer facing away from the flexible screen 200; the polarizer and optical adhesive layer at the connection point of the first flexible screen 210 and the second flexible screen 220 are cut to form a third cutout 620, reducing the bending stress caused by the polarizer and optical adhesive layer when the flexible screen 200 is bent. In this embodiment, the optical adhesive layer can reduce wear on the flexible screen 200. It should be noted that attaching the polarizer and optical adhesive layer can occur before or after the flexible screen 200 is attached to the guide film 100.

[0064] Excess membrane structure is removed by outer contour cutting; laser positioning and drilling are used to form a first positioning hole 121 and / or a second positioning hole 151; inner contour cutting is used to form a break area 140; it should be noted that the order of outer contour cutting and drilling inner contour cutting can be changed arbitrarily, and can also occur before attaching the flexible screen 200.

[0065] In this embodiment, the first positioning hole 121 is located on the side of the first main body portion 110 away from the second main body portion 120. The first positioning hole 121 is a hole drilled in the second main body portion 120, and the first positioning hole 121 is provided on the side away from the first main body portion 110, and the first positioning holes 121 are provided at intervals along the outer periphery of the fan shape.

The length of the extension 150 may not exceed the outermost edge of the second main body 120. In this embodiment, the extension 150 passes through the opening segment 122, such that the extension 150 is at least partially located outside the second main body 120. In this embodiment, the second positioning hole 151 is located on the extension 150. Figure 3 The second positioning hole 151 is spaced apart from one end near the first main body 110 to the end away from the first main body 110. The second positioning hole 151, together with the first positioning hole 121, can better position the first main body 110 and the second main body 120, thereby improving the bonding accuracy of the main and sub screens.

[0067] Specifically, in this embodiment, the entire structure is cut along its inner contour to form a first main body 110, a second main body 120, a connecting portion 130, an extension 150, a binding support portion 160, a break area 140, and an opening segment 122. In this embodiment, the first main body 110 and the second main body 120 are connected together by the connecting portion 130. The connection between the second main body 120 and the first main body 110 allows the first main body 110 to move when adjusting its attachment position, thereby adjusting the overall attachment accuracy. In this embodiment, the connecting portion 130 connects the first main body 110 and the second main body 120. The connecting portion 130 is attached to the connection position of the first flexible screen 210 and the second flexible screen 220 of the flexible screen body 200. The break area 140 is located between the second main body 120 and the first main body 110, and is located on both sides of the connecting portion 130. The disconnection zone 140 can reduce the stress around the second flexible screen 220 when it is bonded to the first flexible screen 210, and reduce the deformation of the second flexible screen 220 during the bonding process, thereby reducing the risk of wrinkles on the curved surface. This improves the bonding yield between the first flexible screen 210 and the second flexible screen 220.

[0068] S13: The first main body 110 is attached to the end face of the support pad 520, and the second main body 120 is attached to the side of the support pad 520 and the side of the base 510, so that the first flexible screen 210 is attached to the end face of the support pad 520 and the second flexible screen 220 is attached to the side of the support pad 520.

[0069] In this embodiment, the support mold 500 includes a support pad 520. The support pad 520 has high rigidity, which facilitates providing support to the guide film 100 and the flexible screen 200. At the same time, the surface of the support pad 520 is relatively soft, so when the guide film 100 guides the flexible screen 200 to adhere to the support mold 500, the damage to the surface of the guide film 100 is small or non-existent, reducing the damage caused by the bending of the second flexible screen 220. When the guide film 100 is attached to the support mold 500, the first main body portion 110 of the guide film 100 is attached to the upper part of the support pad 520 of the support mold 500 in the Y direction, and the second main body portion 120 of the guide film 100 is attached to the side of the support pad 520 of the support mold 500. The side of the support mold 500 includes the side of the frustum. The first main body portion 110 and the second main body portion 120 are attached to different planes of the support pad 520, so that when the second main body portion 120 surrounds the first main body portion 110, wrinkles are reduced in the second main body portion 120, and the adhesion effect of the guide film 100 when it is attached to the support mold 500 is improved.

[0070] In another embodiment of this application, a plurality of positioning posts 511 are provided on the side of the base 510. When the guide film 100 is attached to the support mold 500, the first positioning hole 121 on the second main body 120 is fitted onto the positioning post 511, and the second main body 120 is attached to the side of the support pad 520 and the side of the base 510. This arrangement of the second main body 120 around the side of the support mold 500 helps to improve the attachment accuracy of the flexible screen 200 to the support mold 500.

[0071] S14: The pressing mold 300 with cover plate 400 is placed on the flexible screen 200, and the cover plate 400, the flexible screen 200, the guide film 100 and the support mold 500 are stacked in sequence.

[0072] In this embodiment, the optical adhesive layer on the flexible screen 200 is removed, that is, the optical adhesive layer on the polarizer is removed.

[0073] In this embodiment, the pressing mold 300 drives the cover plate 400 to vacuum cover the flexible screen 200, pressurizes and removes air bubbles between the flexible screen 200 and the guide film 100, and uses ultraviolet light to cure the optical adhesive.

[0074] S15: Remove at least a portion of the cover plate 400, flexible screen 200 and guide film 100 from the support mold 500, remove the guide film 100, and obtain the display device.

[0075] In this embodiment, at least a portion of the cover plate 400, flexible screen 200, and guide film 100 are detached from the support mold 500, and the guide film 100 is removed to obtain the display device. (See also...) Figure 1 , Figure 1 This is a three-dimensional structural diagram of an embodiment of the module of this application.

[0076] In another embodiment of this application, the method further includes retracting the positioning post 511 into the base 510, thereby disengaging the cover plate 400, the flexible screen 200, and the guide film 100 from the supporting mold 500. (See also...) Figure 8 The supporting mold 500 includes a telescopic drive mechanism for driving the positioning post 511 to extend to the side of the base 510 or retract into the base 510. In other embodiments, see [reference needed]. Figure 7 Alternatively, the telescopic drive mechanism can be omitted. The guide film 100 above the positioning post 511 can be cut around its circumference, separating a portion of the guide film 100 from the positioning post 511. This ensures that the positioning post 511 does not interfere with the peeling of the guide film 100 below the flexible screen 200, facilitating the removal of the guide film 100 from the support mold 500 and the flexible screen 200. Here, "above the positioning post 511" refers to the area above the positioning post 511 along the direction from the positioning post 511 to the support pad 520.

[0077] The method for manufacturing the display device according to the embodiments of this application, by adopting the bonding device of the above embodiments of this application, facilitates fixing the first flexible screen 210 and the second flexible screen 220 of the flexible screen 200 onto the support mold 500, facilitates the alignment and bonding of the cover plate 400 with the flexible screen 200, reduces air bubbles generated during bonding, and improves the bonding yield.

[0078] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
