Referring to fig. 1 and fig. 3a to 3c, fig. 1 is a schematic flow chart illustrating a manufacturing method of a display device 100 according to a first embodiment of the invention, and fig. 3a to 3c are schematic process flow charts illustrating the manufacturing method of the display device 100 according to the first embodiment of the invention.
As shown in fig. 1, 3a and 3b, the method of manufacturing the display device 100 may include the steps of:
providing step S101: providing a flexible display panel 110, the flexible display panel 110 having first and second opposing sides 110a, 110 b;
deformation layer forming step S102: the first deformation layer 120 and the second deformation layer 130 are 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 of the present invention, the flexible display panel 110 has a certain Elastic Modulus (Elastic Modulus), so that the flexible display panel 110 can be deformed, such as stretched, bent, and curled.
In some embodiments according to the present invention, the first deformation layer and the second deformation layer, which are also capable of performing deformation operations, may be attached to the first side and the second side of the flexible display panel after being deformed, such as stretched, bent, and curled, so that the flexible display panel may be in a contracted state after the first deformation layer and the second deformation layer rebound from the deformed state to an undeformed state, thereby generating a larger deformation amount when performing deformation operations on the display device having the flexible display panel in the contracted state, and further enabling the display device after deformation to have a larger display area compared to the display device before deformation.
Further, compared to the aforementioned deformation operations such as stretching, bending and curling performed on the first deformation layer and the second deformation layer, in the present embodiment, the deformation operations of hot pressing the first deformation layer 120 and the second deformation layer 130 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 attached 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 deformation operation is performed on the display device 100 having the flexible display panel 110 in the contracted state, a larger deformation amount can be generated, and the deformed display device 100 has a larger display area compared to the display device 100 before deformation.
It should be noted that, in the present embodiment, since the first deformation layer 120 and the second deformation layer 130 are formed by thermal compression, compared to a display device formed by laminating the first deformation layer and the second deformation layer on the flexible display panel in a manner of stretching, bending, and curling, for example, the display device 100 in the present embodiment is subjected to less stress after stretching the same length, so that the display device 100 has better stability.
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 hot 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, film layers 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, please refer to fig. 2 and fig. 3a, wherein fig. 2 is a schematic flow chart of a method for manufacturing a display device 100 according to a first embodiment of the present invention, and as shown in fig. 2 and fig. 3a, before the step S102 for forming a deformation layer, the method further includes:
support layer forming step S103: a first support layer 140 and a second support layer 150 are attached to the first side 110a and the second side 110b, respectively.
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 supporting layer 140 and the second supporting 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 fig. 3b, in this embodiment, the deformation layer forming step S102 specifically includes:
after the first deformation layer 120 and the second deformation layer 130 are hot-pressed, the first support layer 140 and the second support layer 150 are respectively attached to the flexible display panel 110, the first support layer 140, and the second support layer 150, which are all 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, a film layer having a waterproof function may be respectively attached to the first deformation layer 120 and the second deformation layer 130, for example, please refer to fig. 2 and fig. 3c, in this embodiment, after the deformation layer forming step S102, the method further includes:
waterproof layer formation 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 material 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 soft oligomer polyol segments and hard diisocyanate-chain extender segments, and may be cast, blown, rolled, or coated to form a film with the advantages of good elasticity, toughness, wear resistance, good cold resistance, environmental protection, and non-toxicity. Further, in this embodiment, the waterproof layer forming step S104 may be performed by hot press molding.
Further, in the present embodiment, the material of the first deformation layer 120 and the second deformation layer 130 may be Thermoplastic polyurethane elastomer (TPU) hot melt adhesive, which can resist high temperature of 110 degrees celsius and low temperature 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, at this time, as shown in fig. 3b and 3c, gaps are formed 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, a flowable material 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 maintain a flat state, that is, may not collapse, before the deformation operation is performed on the display device 100.

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 and second waterproof layers 160 and 170 are disposed on the first and second deformation layers 120 and 130, respectively.
Specifically, in the present embodiment, the first support layer 140 and the second support layer 150 are used as a support structure and a protection structure 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 a waterproof structure of the display device 100, so that the display device 100 has a certain waterproof property.

Referring to fig. 5 and fig. 6, wherein fig. 5 shows a schematic flow chart of a manufacturing method of a display device 200 according to a second embodiment of the present invention, fig. 6 shows a schematic structural diagram of the display device 200 according to the second embodiment of the present invention, and as shown in fig. 5 and fig. 6, the manufacturing method of the display device 200 may specifically include the following steps:
