Wherein, the ductility that guide film 10 corresponds in different regions is different to the ductility of the different regions of adaptation flexible display module assembly 20, thereby ensure that the guide film carries flexible display module assembly 20 and in the laminating process with curved surface apron 30, different shapes of laminating curved surface apron 30 that can be better can not receive the restriction. It should be noted that, the specific material of the guide film 10 is not particularly limited in the embodiment of the present invention, for example, the first region 11 is made of polyethylene terephthalate (PET), the second region 12 is made of rubber, and the thicknesses of the two regions are the same, so as to ensure that the attaching effect is better.

It should be noted that, the specific shape and structure of the supporting layer 40, which are not limited in the embodiments of the present invention, may be selectively set according to actual situations, for example, a rectangular structure, so as to ensure that when the flexible display module 20 and the curved cover 30 are attached to each other, the entire curved edge 31 of the curved cover 30 can be effectively supported, and thus, the flexible display module 20 is prevented from being extruded and seriously deformed. In addition, the thickness of supporting layer 40 can keep unanimous with the thickness of flexible display module assembly 20, and specific thickness can set up according to actual conditions selectivity, avoids thickness too little can't play the supporting role to curved surface edge 31, also avoids thickness too big simultaneously for flexible display module assembly 20 can't fully laminate with curved surface apron 30.
Optionally, the supporting layer 40 includes polyethylene glycol terephthalate PET, polyurethane PU or foam for the supporting layer 40 has higher elasticity, guarantees to play better supporting role when the flexible display module 20 is laminated with the curved surface apron 30, and can not damage the curved surface apron 30. In addition, the polyethylene terephthalate PET, the polyurethane PU or the foam cotton have the advantages of no pollution and low cost.
Optionally, fig. 2 is a schematic top view structure diagram of a curved screen attaching apparatus according to an embodiment of the present invention, fig. 3 is a schematic cross-sectional structure diagram of another curved screen attaching apparatus according to an embodiment of the present invention, and with reference to fig. 2 and fig. 3, the curved cover plate 30 includes a first curved edge 311 and a second curved edge 312 that are oppositely disposed; the support layer 40 includes a first support layer 41 and a second support layer 42, the first support layer 41 is used for supporting the first curved edge 311 when the flexible display module 20 and the curved cover plate 30 are attached, and the second support layer 42 is used for supporting the second curved edge 312 when the flexible display module 20 and the curved cover plate 30 are attached.
Specifically, taking the rectangular top view structure of the curved cover plate 30 as an example, fig. 2 exemplarily shows a schematic top view structure of the curved screen attaching device, the left and right sides of the curved cover plate 30 are both curved edges, that is, the region from the right dotted line to the right side in fig. 2 is the first curved edge 311, and the region from the left dotted line to the left side is the second curved edge 312. Accordingly, the support layer 40 includes a first support layer 41 and a second support layer 42, the first support layer 41 is disposed corresponding to the first curved edge 311, and the second support layer 42 is disposed corresponding to the second curved edge 312.

Correspondingly, the supporting layer 40 sets up around the first region 11 of guide membrane 10 for when flexible display module assembly 20 and curved surface apron 30 laminating, supporting layer 40 can play the supporting role to all edges of curved surface apron 30, in order to guarantee at the laminating in-process, flexible display module assembly 20 can not receive the extrusion and warp, improves the performance of product, guarantees that the curved surface screen has good display effect.
Optionally, fig. 5 is a schematic cross-sectional view of a part of the curved-surface screen laminating apparatus provided in the embodiment of the present invention before laminating, and as shown in fig. 5, the thickness of the flexible display module 20 is d1The thickness of the support layer 40 is d2，0.5d1≤d2≤1.5d1。
Specifically, the thickness of the flexible display module 20 is set to d1The thickness of the support layer 40 is d2The thickness of the supporting layer 40 can be different according to the different stress of the flexible display module 20 in the attaching process or the different materials of the supporting layer 40, and the thickness of the supporting layer 40 can be selectively set according to actual conditions to be d2Satisfy the relation 0.5d1≤d2≤1.5d1Not only can ensure that the flexible display module 20 can have a better laminating effect with the curved cover plate 30, but also can prevent the flexible display module 20 from being excessively extrudedSevere deformation occurs to affect the performance of the product. Illustratively, the overall thickness d of the flexible display module 201Can be 300um, the thickness d of the support layer 402Can be 150um to 450 um.
It can be understood that fig. 6 is a schematic view of a partial cross-sectional structure of a curved panel attaching device after attaching according to an embodiment of the present invention, and with reference to fig. 5 and 6, in a process of attaching the flexible display module 20 to the curved cover 30, the flexible display module 20 deforms under extension of the guide film 10 (refer to a dotted line in fig. 6), so that a thickness of an edge of the display module 20 is smaller than thicknesses of other positions, and thus, a thickness d of the support layer 40 may be set as2Can be slightly smaller than the thickness d of the flexible display module 201。
In addition, if the supporting layer 40 is made of foam, it has certain elasticity, and when the thickness of the flexible display module 20 is d1The thickness of the support layer 40 may be set to d2Is slightly larger than d1The support layer 40 can still be ensured to have a better supporting effect on the curved edge 31 during the fitting process.
