Description

Technical Field

[0001] The present disclosure relates to an electronic device including a flexible display. Background Art

[0002] Electronic devices have gradually become thinner and have been improved to simultaneously increase rigidity, strengthen their design, and differentiate their functional elements. The shape of electronic devices has deviated from the usual rectangular shape and has gradually been changed to various shapes. Electronic devices may have a deformable structure that is easy to carry and can include a large screen display. For example, as part of the deformable structure, the electronic device may include a foldable housing that operates to fold or unfold relative to each other. Such an electronic device may require a support structure that can reduce deformation of the flexible display caused by frequent folding operations. Summary of the invention

[0003] Technical issues

[0004] The foldable electronic device may include a hinge device (e.g., a hinge structure or a hinge module) and a first shell and a second shell, the first shell and the second shell being connected in a foldable manner in a direction in which they face each other by the hinge device. Such a foldable electronic device can be operated in an inward folding and / or outward folding manner, wherein the first shell is rotated relative to the second shell in a range of 0 to 360 degrees by the hinge module. The foldable electronic device may include a flexible display, which is configured to be at least partially supported by the first shell and the second shell in the unfolded state of the foldable electronic device. Such a flexible display may include a plurality of layers (e.g., a protective layer, a polarizing layer (POL), a polymer layer, or at least one functional layer) arranged on an upper surface and / or a lower surface based on a display panel.

[0005] For thinning of the foldable electronic device, a protective cover (e.g., a decorative cover or a protective frame) disposed so that an edge portion (e.g., an edge) of the display of the flexible display is not visible from the outside may be omitted. For example, in an electronic device in which the protective cover is omitted, the flexible display may be disposed so that its edge is visible from the outside while being supported by the first housing and the second housing.

[0006] In this case, since an edge portion including a bent portion extending from a display panel of the flexible display (e.g., a chip on panel or a chip on plastic (COP)) is vulnerable to external impact damage, a failure may occur due to its damage. In addition, since static electricity (e.g., electrostatic discharge (ESD)) that has entered a space between the housing and the flexible display panel is guided along the bent portion, it may electrically damage the display panel. In addition, foreign matter or moisture that has entered between the housing and the flexible display may enter between multiple layers of the flexible display, so the flexible display may be waterproof and fragile.

[0007] According to various embodiments of the present disclosure, there may be provided an electronic device including a flexible display having improved durability against external impact by the electronic device including a protective structure for a bent portion of a display panel.

[0008] According to various embodiments of the present disclosure, there may be provided an electronic device including a flexible display including a waterproof structure for preventing external moisture or foreign substances.

[0009] According to various embodiments of the present disclosure, an electronic device including a flexible display having a protective structure providing improved surface quality considering the amount of sliding of the flexible display and improved durability against external impact and folding may be provided.

[0093] According to various embodiments, the second filling member 520 filling the second space 400b may be formed of a material having a molded part modulus value of about 10MPa or less when the molding liquid is solidified. In a certain embodiment, the second filling member 520 may be formed of a material having a molded part modulus value of about 5MPa or less when the molding liquid is solidified. In a certain embodiment, the second filling member 520 may be formed of a material having a molded part modulus value of about 1MPa or less when the molding liquid is solidified. According to an embodiment, the second filling member 520 may be solidified by a silicone series molding liquid. According to an embodiment, since the second filling member 520 accommodates the sliding phenomenon between the layers of the first display 400 (e.g., the window layer 410 and the display panel 430) that occurs through the folding / unfolding operation of the electronic device 100, it is possible to reduce the occurrence of degradation such as a buckling phenomenon to help improve the surface quality of the first display 400. According to an embodiment, since the second filling member 520 filling the second space 400b blocks the second space 400b between the window layer 410 and the display panel 430 at the first edge 401 of the first display 400, an improved protection structure can be provided to prevent electrostatic discharge (ESD) from flowing from the outside to the display panel 430 through the bent portion 432, and can help improve waterproof performance by suppressing the penetration of external foreign matter and / or moisture. In a certain embodiment, the second filling member 520 can be omitted.

[0094] [Table 1]

[0095]

[0096] Table 1 above indicates the comparative values ​​of the panel sliding amount and the panel stress in the case where the second filling member 520 is omitted in the second space 400b or the second filling member 520 having the molded part modulus value of 1 MPa and 10 MPa is applied in the second space 400b, compared with the comparative example in which the first filling member 510 is applied to the second space 400b in the state where the first filling member 521 having the molded part modulus value of 100 MPa is applied in the first space 400a. For example, in the case where the second filling member 520 is not applied or the second filling member 520 having the molded part modulus value smaller than that of the first filling member 510 is applied in the second space 400b, it can be understood that the panel stress is reduced by about 50% to 90% compared with the comparative example. This may mean that if the second filling member 520 is omitted, or a second filling member 520 having a molding modulus value smaller than that of the first filling member 510 is applied in the second space 400b, the panel sliding amount is relatively increased, and degradation phenomena such as buckling phenomena near the first edge 401 of the first display 400 are reduced.

[0097] Figure 6 is a process flow diagram for applying a filling member to a flexible display according to various embodiments of the present disclosure. 7A to 7E is a schematic diagram illustrating a process for applying a filling member to a flexible display according to various embodiments of the present disclosure.

[0098] Reference Figures 6 to 7E and Figure 5 The first process 601 may include an operation of filling the second space 400b between the window layer 410 of the first display 400 and the display panel 430 with the molding liquid 520'. According to one embodiment, as Fig. 7A and Figure 7B As shown, a guide tape 530 may be attached so as to close the second space 400b between the bent portion 432 and the window layer 410 along the length direction at the first edge 401 of the first display 400. According to one embodiment, in a state where the guide tape 530 is attached, the molding liquid 520' may be injected into one end of the first edge 401 of the first display 400 through the molding syringe 540. In this case, the outer side of the bent portion 432 may be protected from the first molding process by the guide tape 530. According to one embodiment, after the molding liquid injection is completed, in the second process 603, the second filling member may be completed by curing the injected molding liquid by means of at least one of natural curing, thermal curing or UV curing. Thereafter, the guide tape 530 may be removed. In a certain embodiment, the first process 610 and the second process 620 may be omitted in the case where the second filling member 520 is excluded from being disposed in the second space 400b.

[0099] According to various embodiments, the third process 605 may include an operation of filling the first space 400a including the bent portion 432 with a hard molding liquid. FIG. 7C to FIG. 7E As shown, the first display 400 including the second filling member 520 disposed in the second space 400b by solidification of the first molding liquid can be aligned with the molding fixture 710 (e.g., Teflon fixture) of the molding device 700. In this case, the first edge 401 of the first display 400 can be disposed between the lower mold 720 and the upper mold 730 at the molding fixture 710. According to an embodiment, the lower mold 720 and the upper mold 730 can be formed of a silicone material. For example, the upper mold 730 may include an inlet 731 for injecting the molding liquid and an outlet 732 for discharging the over-injected molding liquid. According to an embodiment, the inlet 731 and the outlet 732 may be disposed at positions corresponding to the two ends of the first space 400a along the length direction at the first edge 401 of the first display 400. For example, in the fourth process 607, if the molding liquid is injected into the inlet 731 of the upper mold 730, the first space 400a including the bent portion 432 of the first display 400 may be filled with the molding liquid, and the molding liquid may be cured by at least one of natural curing, thermal curing, or UV curing. Thereafter, if the lower mold 720 and the upper mold 730 are separated from each other, and the first display 400 is separated from the molding jig 710, the first filling member 510 may remain in a fixed state so as to at least surround the bent portion 432 at the first edge 401 of the first display 400. In a certain embodiment, when the first display 400 is disposed in the electronic device 100, the first filling member 510 may be formed to have a size and / or shape that can be supported by the second side member 123 of the second housing 120.

[0102] refer to Fig. 8A, the electronic device 100 may include a first filling member 510 disposed in the first space 400a including at least the bent portion 432. In this case, since the second space 400b between the window layer 410 and the display panel 430 does not include any filling member, it can accommodate a sliding phenomenon between layers of the first display 400 according to a folding / unfolding operation of the electronic device 100, thereby helping to reduce inferior quality such as a buckling phenomenon.

[0103] refer to Figure 8B , the electronic device 100 may include a first filling member 510 disposed in the first space 400a including at least the bent portion 432.

According to an embodiment, the second space 400b may be sealed by an adhesive member P5 disposed between the window layer 410 and the display panel 430. According to an embodiment, since the penetration of external foreign matter and / or moisture can be prevented by the sealing structure of the second space 400b by means of the adhesive member P5, the sealing structure can improve the waterproof performance and help solve the ESD problem.

[0104] refer to Figure 8C , the electronic device 100 may include a first filling member 510 disposed in a first space 400a including at least a bent portion 432. In this case, the second space 400b between the window layer 410 and the display panel 430 may not include any filling member. According to an embodiment, because at least a portion of the window layer 410 extends with the adhesive member and is attached to the bent portion 432 through the adhesive member, the second space 400b can be sealed. For example, when the flexible display is viewed from above, the second space 400b can help the sealing structure in a manner that the glass layer (UTG) of the window layer and the end of the adhesive member extend until at least a portion of the bent portion overlaps each other. Since the sealing structure can prevent the penetration of external foreign matter and / or moisture, it can improve the waterproof performance and help solve the ESD problem.
