The first connection region 112a, the second connection region 112b, the third connection region 112c, and the fourth connection region 112d are disposed corresponding to one corner of the main display region 110, respectively.

Further, the flexible screen 11 is configured to be attached to the surface of the curved cover 12 facing the curved portion 121 and the connecting portion 122, that is, the flexible screen 11 is configured to be attached to the attaching surface of the curved cover 12. It can be appreciated that, based on the soft and bendable property of the flexible screen 10 and the above structural configuration of the curved cover 12, when the flexible screen 11 is attached to the curved cover 12, the main display area 110 of the flexible screen 11 is attached to the main body 120 of the curved cover 12, the curved display area 111 is attached to the curved portion 121, and the connection area 112 is attached to the connection portion 122, so that the curved display area 111 and the connection area 112 can exhibit a curved configuration corresponding to the curved configuration under the action of the curved structural configuration of the curved portion 121 and the connection portion 122 of the curved cover 12.
Based on the structural form of the curved surface cover plate, in the process of attaching the flexible screen to the curved surface cover plate, attaching bubbles are easily generated in the connecting area of the connecting part of the flexible screen corresponding to the corner position of the curved surface cover plate, and then the appearance performance and the attaching yield of the display screen assembly are affected.
Therefore, the applicant has studied and proposed a bonding method suitable for the display screen assembly, so as to avoid defects such as bonding bubbles at the corner, i.e. the connection area, of the display screen assembly.
Referring to fig. 7, fig. 7 is a flow chart of a method for attaching a display assembly according to some embodiments of the present application, wherein the display assembly may be the display assembly 10 described in the previous embodiments.
The fitting method generally includes, but is not limited to, the following steps:
step S701, providing a curved cover plate and a flexible screen. The curved cover plate may be the curved cover plate in the foregoing embodiment, and the flexible screen may be the flexible screen in the foregoing embodiment, which will not be described in detail herein.
Step S702 provides a carrier assembly having a carrying surface for carrying a flexible screen.
Referring to fig. 8 and 9, fig. 8 is a schematic structural view of the carrier assembly 50 according to some embodiments of the present application, and fig. 9 is a schematic structural view of another state of the carrier assembly 50 according to the embodiment of fig. 8. A schematic structural view of the initial configuration of the carrier assembly 50 is shown in fig. 8, i.e., the initial configuration when the flexible screen is carried and ready to be attached to a curved cover plate. Fig. 9 is a schematic structural diagram of the carrier assembly 50 when the flexible screen and the curved cover plate are completely attached, that is, an attaching form of the carrier assembly 50 when the flexible screen and the curved cover plate are completely attached by the carrier assembly 50.
Specifically, the carrier assembly 50 generally includes a main carrier 51 and a corner carrier 52 provided at a corner position of the main carrier 51. The same side surfaces of the main carrier 51 and the corner carrier 52 cooperate to form a bearing surface for carrying the flexible screen. Wherein the main carrier 51 and the corner carrier 52 are detachable, i.e. in the initial configuration of the carrier assembly 50, the edges of the main carrier 51 abut the edges of the corner carrier 52. In the attached configuration of the carrier assembly 50, the main carrier 51 and the corner carrier 52 are spaced apart. Further, the shape of the carrier assembly 50 is adapted to the shape of the curved cover, and the carrier assembly 50 is also generally rectangular in shape based on the generally rectangular shape of the curved cover in the foregoing embodiments. Of course, in other embodiments, the overall morphology of the carrier assembly 50 may be adapted as the morphology of the curved cover changes.
In an embodiment, the shape of the bearing surface may be adapted to the shape of the surface of the curved cover plate that conforms to the flexible screen. Of course, in other embodiments, the shape of the bearing surface may be adapted to the shape of the surface of the main body portion of the curved cover plate that conforms to the main display area of the flexible screen.
In one embodiment, the main carrier 51 has a substantially rectangular configuration with corner notches, and the corner carrier 52 is located at the corner notch position of the main carrier 51. Wherein the corner carrier 52 is movable in a direction of a line connecting the center of the main carrier 51 with the center of the corner thereof, thereby enabling the corner carrier 52 to be switched between an abutting state and an interval state with the main carrier 51.
In other words, the corner carrier 52 may be moved in a direction in which the main carrier 51 points toward the corner carrier 52, thereby enabling the corner carrier 52 to be switched with the main carrier 51 between the abutting state and the spaced state. For example, the corner carrier 52a may be moved in the direction of the line connecting the center of the main carrier 51 and the center of the corner carrier 52a, as shown in the Y1 direction of fig. 8. As another example, adjacent sides of the corner carrier 52b are successively shifted with the corresponding edges of the main carrier 51 between the abutting state and the spaced state, respectively, as in the Y2 direction shown in fig. 8. Of course, other movement means may be employed between the corner carrier 52 and the main carrier 51 to enable the corner carrier 52 to be switched between the abutting state and the spaced state with the main carrier 51, which is not particularly limited in the embodiment of the present application.
Specifically, the corner carrier 52 generally includes a first corner carrier 52a corresponding to a first connection, a second corner carrier 52b corresponding to a second connection, a third corner carrier 52c corresponding to a third connection, and a fourth corner carrier 52d corresponding to a fourth connection. During the movement of the carrier assembly 50 from the initial configuration to the fitted configuration, the first corner carrier 52a is moved in the direction of the main carrier 51 pointing to the first corner carrier 52a, the second corner carrier 52b is moved in the direction of the main carrier 51 pointing to the second corner carrier 52b, the third corner carrier 52c is moved in the direction of the main carrier 51 pointing to the third corner carrier 52c, and the fourth corner carrier 52d is moved in the direction of the main carrier 51 pointing to the fourth corner carrier 52d. In other words, during movement of the carrier assembly 50 from the initial configuration to the conforming configuration, the corner carrier 52 moves in a direction in which the main carrier 51 points toward the corner carrier 52; during the transition of the carrier assembly 50 from the conformable configuration to the initial configuration, the corner carrier 52 moves in a direction in which the corner carrier 52 points toward the main carrier 51.
Step S703, covering the flexible screen on the carrying surface of the carrier assembly. I.e. the flexible screen is contoured by the bearing surface of the carrier assembly. In other words, the flexible screen is covered on the bearing surface to prepare for fitting. It will be appreciated that based on the flexible pliable nature of the flexible screen, the flexible screen may assume an appearance generally conforming to the bearing surface when the flexible screen is overlaid on the bearing surface to profile the flexible screen. It should be noted that, based on the above characteristics of the flexible screen, the flexible screen may exhibit a curvature that is adapted to the shape of the bearing surface when the flexible screen is covered on the bearing surface, or may be understood that when the flexible screen is covered on the bearing surface, the flexible screen may be in a non-full-contact form with the bearing surface, and a local area between the flexible screen and the bearing surface may have a tiny gap.
Preferably, the flexible screen is flattened over the bearing surface of the carrier assembly to contour the flexible screen through the bearing surface of the carrier assembly.
Step S704, moving the main carrier 51 and the corner carrier 52, and/or moving the curved cover plate so that the flexible screen and the curved cover plate come closer to each other until they are in contact. Specifically, the main carrier 51 and the corner carrier 52 may be moved simultaneously, or one of the main carrier 51 and the corner carrier 52 may be moved first and then the other one thereof, which is not particularly limited in the embodiment of the present application.
Step S705, moving the corner carrier 52 along the direction in which the main carrier 51 points to the corner carrier 52, so that the corner area of the flexible screen is attached to the corresponding position of the curved cover plate.
It will be appreciated that after the flexible screen 11 is attached to the curved cover 12 in the above manner, the carrier assembly 50 is removed to obtain the display screen assembly described in the foregoing embodiments of the present application.
Referring to fig. 10 in combination, fig. 10 is a schematic structural diagram corresponding to a bonding process of a display screen assembly in some embodiments of the present application, where fig. 10a illustrates a schematic structural diagram before bonding a flexible screen and a curved cover plate, fig. 10b illustrates a schematic structural diagram when the flexible screen contacts the curved cover plate, and fig. 10c illustrates a schematic structural diagram when the flexible screen is bonded to the curved cover plate.
As shown in fig. 10a, before the flexible screen 11 is attached to the curved cover plate 12, the flexible screen 11 is flattened and covered on the bearing surface 501 of the carrier assembly 50, that is, the flexible screen 11 is profiled with reference to the bearing surface 501. Wherein, when the flexible screen 11 is attached to the curved cover 12, the bearing surface 501 is approximately the surface of the carrier assembly 50 near the curved cover 12. Further, the same side surfaces of the main carrier 51 and the corner carrier 52 cooperate to form a bearing surface 501, that is, a first bearing surface 501a is formed on one side of the main carrier 51 close to the curved cover plate 12, a second bearing surface 501b is formed on one side of the corner carrier 52 close to the curved cover plate 12, and the first bearing surface 501a and the second bearing surface 501b cooperate to form the bearing surface 501.
Further, the main carrier 51 and the corner carrier 52, i.e., the carrier assembly 50 as a whole, are moved synchronously so that the flexible screen 11 and the curved cover plate 12 come gradually closer to each other until they come into contact. Of course, the flexible screen 11 and the curved cover plate 12 may also be brought into close proximity until they come into contact by moving the curved cover plate 12. Alternatively, the entire carrier assembly 50 and curved cover plate 12 may be moved simultaneously so that the flexible screen 11 and curved cover plate 12 come into close proximity until they come into contact. As shown in fig. 10a, taking the case of moving the curved cover plate 12, the curved cover plate 12 is moved in a direction (F1 direction) approaching the flexible screen 11 until the flexible screen 11 and the curved cover plate 12 come into contact (as shown in fig. 10 b). In other words, the flexible screen 11 and the curved cover plate 12 are brought into close proximity by moving at least one of the carrier assembly 50 and the curved cover plate 12 until they come into contact to form the pre-applied configuration. It will be appreciated that when the flexible screen 11 and the curved cover 12 are brought into contact, i.e. in a pre-applied configuration, the first bearing surface 501a and the second bearing surface 501b cooperate to form a complete bearing surface 501. In other words, in the initial configuration of the carrier assembly 50, there is a smooth transition between the first bearing surface 501a and the second bearing surface 501 b.
It will be appreciated that after the flexible screen 11 is flattened to cover the bearing surface 501, and before the flexible screen 11 contacts the curved cover plate 12, it may further comprise: the flexible screen 11 is aligned with the curved cover plate 12. That is, the flexible screen 11 and the curved cover plate 12 generally need to be aligned prior to moving at least one of the carrier assembly 50 and the curved cover plate 12 to ensure accuracy of the fit. Preferably, after positioning between the flexible screen 11 and the curved cover plate 12 is completed, at least one of the carrier assembly 50 and the curved cover plate 12 is moved such that the flexible screen 11 and the curved cover plate 12 come into close proximity until they come into contact to form a pre-fit configuration. In other words, after the flexible screen is contoured, the flexible screen 11 and the curved cover plate 12 are positioned, and the bonding operation is performed after the positioning is completed. After the positioning is completed, the main carrier 51 is disposed opposite to the main body 120 and/or the curved portion 121 of the curved cover 12, and the corner carrier 52 is disposed corresponding to the connecting portion 122 of the curved cover 12.
After the pre-attachment of the flexible screen 11 and the curved cover plate 12 is completed, as shown in fig. 10b, the corner carrier 52 is moved in a direction in which the main carrier 51 is directed toward the corner carrier 52, so that the corner regions of the flexible screen 11 are attached to the corresponding positions of the curved cover plate (as shown in fig. 10 c). I.e. the corner carrier 52 is moved in the direction of the corner carrier 52 away from the main carrier 51 (direction F2) as shown in fig. 10b, so that the connection region 112 of the flexible screen 11 is completely attached to the connection portion 122 of the curved cover plate 12, avoiding the occurrence of attaching bubbles. As shown in fig. 10c, when the corner carrier 52 moves to be spaced from the main carrier 51, the corner carrier 52 may promote the connection region 112 of the flexible screen 11 to completely adhere to the connection portion 122 of the curved cover plate 12, so as to avoid the occurrence of adhering bubbles. Preferably, when the attachment region 112 of the flexible screen 11 is fully engaged with the attachment portion 122 of the curved cover plate 12, the spacing L between the corner carrier 52 and the main carrier 51 is generally no more than 2mm, for example, may be 1mm, 1.5mm, etc.
In one embodiment, the carrier assembly 50 is made of a material capable of undergoing a certain elastic deformation under the action of an external force, for example, an elastic material such as silica gel or rubber. I.e. the main carrier 51 and/or the corner carrier 52 may be made of an elastic material such as silicone, rubber or the like. The thickness of the carrier assembly 50 is typically 2-10cm, such as 3cm, 4cm, 5cm, etc. It should be noted that, the carrier assembly 50 has a too thin thickness, and the range of deformation expansion caused by stress is limited, which is not beneficial to the uniform stress of the flexible screen; the thickness of the carrier assembly 50 is too thick, and the deformation can be performed only by bearing a large force, so that the flexibility of the deformation is limited, and the uniform stress of the flexible screen is also not facilitated. The hardness of the carrier assembly 50 is generally no more than 40A, and the carrier assembly 50 is too hard and is prone to damage to the flexible screen.
It can be understood that the carrier component made of elastic materials can deform the carrier component through the action of external force after the flexible screen and the curved cover plate borne on the carrier component are pre-attached, so that the attachment of the flexible screen and the curved cover plate is completed. Further, the surface of the flexible screen, which is attached to the curved cover plate, is provided with colloid, and/or the surface of the curved cover plate, which is attached to the flexible screen, is provided with colloid. The colloid is enabled to gradually fill gaps between the curved cover plate and the flexible screen under the action of external force so as to complete the lamination. Further, the matching degree between the carrier assembly and the curved cover plate during lamination is optimized, lamination bubbles generated in the corner area can be eliminated or avoided, and lamination yield is improved.
Wherein, through setting up with the separable bight carrier of main carrier, realize laminating in advance between flexible screen and the curved surface apron through main carrier and bight carrier cooperation, further make the bight regional atress of flexible screen even abundant through the removal of bight carrier, and then make fully laminating between the bight region of flexible screen and the bight position of curved surface apron, so eliminate or avoid the laminating bubble that produces in the bight region, and then can promote laminating yield.
Based on the elastic material of the carrier component, the outer periphery of the carrier component has a certain inward shrinkage compared with the edge of the curved cover plate, namely, when the flexible screen and the curved cover plate are aligned or pre-bonded, the outer periphery of the carrier component does not exceed the edge of the bonding surface of the curved cover plate and a gap M is formed between the outer periphery of the carrier component and the edge of the bonding surface of the curved cover plate, wherein the gap M is generally not more than 1mm, for example, can be 0.3mm, 0.5mm and the like. In other words, when the flexible screen and the curved cover plate are aligned or pre-attached, the projection of the carrier component projected onto the curved cover plate does not exceed the edge of the attaching surface of the curved cover plate.
In the actual lamination process, the main carrier is borne in the main display area and the bending display area of the flexible screen, and the pre-lamination of the flexible screen and the curved cover plate is realized by the main carrier, namely the alignment lamination of the main display area and the main body part and the alignment lamination of the bending display area and the bending part. The corner carrier is then brought into abutment with the main carrier and spaced from the outer edge of the curved portion, and then the pre-attachment of the connecting region of the flexible screen to the connecting portion of the curved cover plate is achieved by moving the corner carrier. Finally, external force is applied to the carrier assembly and/or the curved cover plate so as to squeeze the colloid between the flexible screen and the curved cover plate, so that the flexible screen and the curved cover plate are completely attached, and attaching bubbles are avoided.
In other words, when the flexible screen and the curved cover plate are aligned or the flexible screen and the curved cover plate are pre-attached, the projection of the main carrier projected onto the curved cover plate does not exceed the edge of the curved cover plate, the projection of the corner carrier projected onto the curved cover plate does not exceed the edge of the connecting portion, and a gap M is formed between the projection of the corner carrier projected onto the curved cover plate and the edge of the connecting portion.
Of course, in some attaching modes, the main carrier and the corner carrier are matched to preferentially realize the alignment attaching of the main display area and the main body part and the alignment attaching of the bending display area and the bending part, and then the corner carrier is moved to enable the connecting area to be fully attached to the connecting part. In particular, in the initial configuration of the carrier assembly, the main carrier and the corner carrier form a carrier body having a complete carrier surface, wherein the flexible screen is flattened to overlie the carrier surface and the outer periphery of the flexible screen may extend slightly beyond the edges of the carrier surface. When the flexible screen and the curved cover plate are aligned and bonded, the main carrier and the main body part of the curved cover plate are aligned so that the projection of the main carrier onto the curved cover plate does not exceed the edge of the curved cover plate; after alignment is completed, the curved surface cover plate is moved and/or the main carrier and the corner carrier are synchronously moved so that the flexible screen is contacted with the curved surface cover plate; and then, external force can be applied to the curved cover plate and/or the carrier component to enable the colloid to fill gaps between the flexible screen and the curved cover plate, so that the main body part is completely attached to the main display area, and the bending part is completely attached to the bending display area.
Of course, in other embodiments, when the flexible screen and the curved cover plate are aligned, the projection of the main carrier projected onto the curved cover plate may be flush with the edge of the curved cover plate, the projection of the corner carrier projected onto the curved cover plate does not exceed the edge of the connecting portion, and a gap M is formed between the corner carrier and the edge of the connecting portion, where the gap M is generally not more than 1mm, for example, may be 0.3mm, 0.5mm, and so on.
Based on the existence of gaussian corner regions (i.e., the cambered surface regions of four corners) in the corner regions, conventional extrusion lamination is extremely prone to lamination bubbles at the edges. Therefore, through setting up carrier assembly into detachable owner carrier and bight carrier, accomplish main part and main display area and laminate completely, after bending portion and the complete laminating of crooked display area, through removing the bight carrier along the directional bight carrier's of owner carrier direction, extrude the bight region of flexible screen and make it laminate completely with the bight position of curved surface apron, the four corners laminating bubble that can avoid causing when conventional laminating is bad, promotes the laminating degree of depth and the laminating yield of flexible screen.
Further, in order to make the flexible screen have better profiling effect when flattening the flexible screen and covering in the loading surface of carrier subassembly, this application is convenient for profiling the flexible screen through providing auxiliary film. Referring to fig. 11 and fig. 12 in combination, fig. 11 is a schematic view of a portion of a process of attaching a display assembly according to some embodiments of the present application, and fig. 12 is a schematic view of a structure corresponding to the portion of the process of fig. 11. Step S703 may further include the following steps:
Step S1101, providing an auxiliary film 60. The auxiliary film 60 may be a flexible film-like structure such as a PI film or a CPI film.
Step S1102, the flexible screen 11 is laid on the auxiliary film 60 in a flattened manner. I.e. the flexible screen 11 is laid over a partial area of the auxiliary film 60 and the edge of the auxiliary film 60 extends beyond the edge of the flexible screen 11.
In step S1103, the auxiliary film 60 is covered on the carrying surface of the carrier assembly, and the flexible screen 11 is located on the side of the auxiliary film 60 facing away from the carrier assembly, so as to profile the flexible screen 11. Specifically, the edge of the auxiliary film 60 exceeds the edge of the bearing surface of the carrier assembly, and the edge of the auxiliary film 60 can be clamped or pulled by hand or a manipulator, so that the auxiliary film 60 is completely matched with the shape of the bearing surface, and the profiling of the flexible screen 11 is further realized.
After the flexible screen 11 is profiled in the above manner, the steps S704 and S705 are continued, and after the flexible screen 11 is attached to the curved cover plate 12, the carrier component and the auxiliary film are removed, so that the display screen component described in the foregoing embodiments of the present application can be obtained.
