Referring to fig. 1 and fig. 3a to fig. 3c, fig. 1 is a schematic flow chart illustrating a method for manufacturing a display device 100 according to a first embodiment of the present invention, and fig. 3a to fig. 3c are schematic flow chart illustrating a method for manufacturing a display device 100 according to a first embodiment of the present invention.
As shown in fig. 1, 3a and 3b, the manufacturing method of the display device 100 may include the steps of:
providing step S101: providing a flexible display panel 110, the flexible display panel 110 having opposite first and second sides 110a, 110b;
deformation layer forming step S102: the first deformation layer 120 and the second deformation layer 130 are respectively attached to the first side 110a and the second side 110b after being hot pressed, so that the flexible display panel 110 is in a contracted state after the first deformation layer 120 and the second deformation layer 130 are cooled.
In the embodiment according to the present invention, the flexible display panel 110 has a certain Elastic Modulus (Elastic Modulus), and thus, the flexible display panel 110 may be subjected to deformation operations such as stretching, bending, and curling.
In some embodiments of the present invention, after the first deformation layer and the second deformation layer, which are also capable of performing deformation operations, are deformed, such as stretching, bending and curling, the first deformation layer and the second deformation layer are attached to the first side and the second side of the flexible display panel, so that the flexible display panel can be in a contracted state after the first deformation layer and the second deformation layer rebound from a deformed state to an undeformed state, and therefore, when the display device having the flexible display panel in the contracted state is subjected to deformation operations, a larger deformation amount can be generated, and the deformed display device has a larger display area than the display device before deformation.
Further, compared to the foregoing deformation operations such as stretching, bending and crimping the first deformation layer and the second deformation layer, in this embodiment, the deformation operations performed on the first deformation layer 120 and the second deformation layer 130 by hot pressing can generate a larger deformation amount on the first deformation layer 120 and the second deformation layer 130, so that after the first deformation layer 120 and the second deformation layer 130 respectively bonded to the first side 110a and the second side 110b by hot pressing are cooled, the flexible display panel 110 can be in a more contracted state, and thus, when the display device 100 with the flexible display panel 110 in a contracted state is subjected to the deformation operation, a larger deformation amount can be generated, so that the deformed display device 100 has a larger display area than the display device 100 before deformation.
In the present embodiment, the first deformation layer 120 and the second deformation layer 130 are formed by thermal compression bonding, so that the display device 100 in the present embodiment is subjected to less stress after being stretched by the same length, and thus the display device 100 has better stability, compared to a display device formed by bonding the first deformation layer and the second deformation layer on a flexible display panel by stretching, bending, and curling, for example.
Further, in the present embodiment, in order to prevent the flexible display panel 110 from being damaged when the first and second deformation layers 120 and 130 after the heat pressing are attached to the first and second sides 110a and 110b of the flexible display panel 110, and in order to make the display device 100 have a certain hardness, a film layer for protecting and supporting the flexible display panel 110 may be attached to the first and second sides 110a and 110b of the flexible display panel 110, respectively.
For example, referring to fig. 2 and fig. 3a, fig. 2 is a schematic flow chart illustrating a further process of the method for manufacturing the display device 100 according to the first embodiment of the present invention, as shown in fig. 2 and fig. 3a, before the deformation layer forming step S102, the method further includes:
support layer forming step S103: the first support layer 140 and the second support layer 150 are respectively attached to the first side 110a and the second side 110 b.
Specifically, in the present embodiment, the first support layer 140 and the second support layer 150 have a certain hardness, and are used as a support structure and a protection structure of the flexible display panel 110.
Note that, since the first support layer 140 and the second support layer 150 are respectively attached to the first side 110a and the second side 110b of the flexible display panel 110, as shown in fig. 2 and 3b, in this embodiment, the deformation layer forming step S102 specifically includes:
the first deformation layer 120 and the second deformation layer 130 are respectively attached to the first support layer 140 and the second support layer 150 after being hot pressed, so that the flexible display panel 110, the first support layer 140 and the second support layer 150 are in a contracted state after the first deformation layer 120 and the second deformation layer 130 are cooled.
Further, in this embodiment, in order to make the display device 100 have a certain waterproof function, film layers having a waterproof function may be respectively attached to the first deformation layer 120 and the second deformation layer 130, for example, please continue to refer to fig. 2 and 3c, and in this embodiment, after the deformation layer forming step S102, the method further includes:
waterproof layer forming step S104: a first waterproof layer 160 is formed on the first deformation layer 120, and a second waterproof layer 170 is formed on the second deformation layer 130.
Specifically, in this embodiment, the materials of the first deformation layer 120, the second deformation layer 130, the first waterproof layer 160 and the second waterproof layer 170 may include thermoplastic polyurethane, which is a linear block copolymer composed of an oligomer polyol soft segment and a diisocyanate-chain extender hard segment, and may be cast, blown, calendered or coated to prepare a film having advantages such as good elasticity, toughness, wear resistance, cold resistance, environmental protection and no toxicity. Further, in the present embodiment, the waterproof layer forming step S104 may be performed by hot press molding.
Further, in the present embodiment, the materials of the first deformation layer 120 and the second deformation layer 130 may be thermoplastic polyurethane elastomer (Thermoplastic Urethane, TPU) hot melt adhesive, which can withstand high temperatures of 110 degrees celsius and low temperatures of minus 20 degrees celsius.
Further, in the present embodiment, since the flexible display panel 110, the first support layer 140 and the second support layer 150 are in the contracted state before the deformation operation is not performed on the display device 100, there are some gaps between the first support layer 140 and the first deformation layer 120 and between the second support layer 150 and the second deformation layer 130 as shown in fig. 3b and 3c, and thus the flowable materials may be filled in the gaps, so that the first deformation layer 120, the second deformation layer 130, the first waterproof layer 160 and the second waterproof layer 170 may be kept in a flat state, i.e., may not collapse, before the deformation operation is not performed on the display device 100.

As shown in fig. 4, the display device 100 is manufactured by the manufacturing method according to the first embodiment of the present invention, and includes: the flexible display panel 110, the first support layer 140, the second support layer 150, the first deformation layer 120, the second deformation layer 130, the first waterproof layer 160, and the second waterproof layer 170, wherein:
the flexible display panel 110 has opposite first and second sides 110a, 110b;

the first deformation layer 120 and the second deformation layer 130 are respectively attached to the first support layer 140 and the second support layer 150 in a hot pressing manner, so that the flexible display panel 110, the first support layer 140 and the second support layer 150 are in a contracted state after the first deformation layer 120 and the second deformation layer 130 are cooled;
the first waterproof layer 160 and the second waterproof layer 170 are disposed on the first deformation layer 120 and the second deformation layer 130, respectively.
Specifically, in the present embodiment, the first supporting layer 140 and the second supporting layer 150 are used as supporting structures and protecting structures of the flexible display panel 110, so that the flexible display panel 110 is not damaged during the process of forming the first deformation layer 120 and the second deformation layer 130, and the first waterproof layer 160 and the second waterproof layer 170 are used as waterproof structures of the display device 100, so that the display device 100 has a certain waterproof property.
