Description

[Technical field]

[0001] The disclosure relates to electronic devices that include waterproof structures. [Background technology]

[0002] Electronic devices are becoming thinner, more rigid, and more sophisticated in design, while their functional elements are being improved to differentiate them. Electronic devices require a sealed waterproof and / or dustproof structure to prevent damage to electronic components disposed in the internal space caused by moisture and / or foreign substances entering from the outside.

[0003] The electronic device includes a first housing, a second housing foldably coupled to the first housing via a hinge device (e.g., a hinge module), and a flexible display arranged to be supported by the second housing. When the first housing and the second housing are folded facing each other, a region of the flexible display corresponding to the hinge device is bent.

[0004] The electronic device includes a waterproof member (e.g., a waterproof tape) disposed between the first housing and the flexible display and between the second housing and the flexible display. The electronic device includes a waterproof structure in which a region corresponding to the first housing and / or a part of a region corresponding to the second housing is sealed via the waterproof member. Such regions include regions where the penetration of moisture that should not escape must be prevented in a folding structure of the electronic device where the inflow of moisture is not possible in the folding region.

[0005] However, a waterproof structure in which a waterproof member is disposed between a housing and a flexible display may cause damage (e.g., tearing) of the flexible display due to the strong adhesive force of the waterproof member when the flexible display must be separated from the housing for maintenance and repair of the electronic device. In addition, if a waterproof member is directly applied to the rear surface of a flexible display, it may be visible from the outside of the flexible display or the surface quality may be deteriorated. In addition, if a digitizer is applied to the lower side of the display panel of a flexible display, the waterproof member is disposed between the digitizer and the housing, which may cause a deterioration in waterproof function due to a step of the digitizer pattern (e.g., coil pattern). Summary of the Invention [Problem to be solved by the invention]

In one embodiment, the first metal sheet layer 4712 and the second metal sheet layer 4722 comprise Cu sheets.

[0073] According to various embodiments, the flexible display 230 includes a bending portion 432 that extends outward from the display panel 430 and is arranged in a folding manner on the rear surface of the flexible display 230 (e.g., the surface of the second reinforcing plate 462). According to one embodiment, the flexible display 230 further includes a bending portion protection layer 4324 (e.g., a bending protection layer (BPL)) that is laminated on the outer surface of the bending portion 432 and protects at least a part of the bending portion 432. According to one embodiment, the bending portion 432 includes an extension portion 4321 that extends from the display panel 430 and includes a control circuit 4321a, and a flexible substrate 4322 that is connected to the extension portion 4321 and includes a plurality of electrical elements.

[0074] According to various embodiments, the control circuit 4321a disposed on the extension portion 4321 is protected through a cover member 485 attached to cover at least a part of the flexible substrate 4322 to at least a part of the extension portion 4321. According to one embodiment, the control circuit 4321a is sealed by being disposed between the flexible substrate 4322 and a third adhesive member T3 disposed between the cover member 485 and the extension portion 4321. According to another embodiment, the third adhesive member T3 is omitted when the size of the control circuit 4321a is small and the distance between the control circuit 4321a and the bending portion protective layer 4324 is large. In such a case, a part of the cover member 485 is directly attached to the extension portion 4321 after bending. According to one embodiment, the third adhesive member T3 is made of a waterproof member (e.g., a waterproof tape). According to one embodiment, the third adhesive member T3 is disposed between the bending portion protective layer 4324 and the control circuit 4321a. According to an embodiment, at least a portion of the cover member 485 is formed of a material having a waterproof structure since it comes into direct contact with external moisture and / or foreign substances. For example, the cover member 485 includes a conductive nonwoven fabric having a randomly arranged conductive fiber structure to prevent external moisture penetration.

[0075] According to various embodiments, the electronic device 200 includes a first waterproof structure WP1 including a first waterproof member 481 disposed between the first reinforcing plate 461 and the first support member 261. According to one embodiment, the first waterproof member 481 provides a first waterproof space (1) 4811, a first waterproof space (2) 4812, and a first waterproof space (3) (e.g., first waterproof space (3) 4813 in FIG. 7 ) between the first reinforcing plate 461 and the first support member 261. According to one embodiment, the first waterproof space (1) 4811 accommodates a through path for a first FPCB connection portion of the first digitizer 471 (e.g., the first FPCB connection portion 4711 in FIG. 6 ). According to one embodiment, the first waterproof space (2) 4812 receives the module receiving hole 2612 formed in the first support member 261 to connect a camera module (e.g., the camera module 216a in FIG. 1a) disposed in the first space (e.g., the first space 2101 in FIG. 7) of the first housing 210 to the display panel 430. According to one embodiment, the first waterproof space (3) 4813 (e.g., the first waterproof space (3) 4813 in FIG. 7) receives at least one electronic component (e.g., a sensor module) disposed through the first housing 210. In another embodiment, the first reinforcing plate 461 includes a hole (e.g., a camera hole) corresponding to the module receiving hole 2612 by extending to a position substantially flush with an edge of the first support member 261.

[0076] According to various embodiments, the electronic device 200 includes a second waterproof structure WP2 including a second waterproof member 482, a third waterproof member 483, and a fourth waterproof member (e.g., the fourth waterproof member 484 in FIG. 7) disposed between the second reinforcing plate 462 and the second support member 262. According to one embodiment, the second waterproof structure WP2 provides a second waterproof space 4821 between the second reinforcing plate 462 and the second support member 262. According to one embodiment, the second waterproof member 482 is disposed on the second reinforcing plate 462 to surround at least a portion of the bending portion 432, the third waterproof member 483 is disposed on the cover member 485, and the fourth waterproof member 484 is disposed to connect a stepped space between the second waterproof member 482 and the third waterproof member 483. According to one embodiment, the second waterproof space 4821 accommodates a through-path for a second FPCB connection portion (e.g., the second FPCB connection portion 4721 in FIG. 6) of the second digitizer 472. According to an embodiment, the second waterproof space 4821 includes a through-path for a third FPCB connection part (e.g., the third FPCB connection part 4323 in FIG. 6) extended from the flexible board 4322. Therefore, the control circuit 4321a and a plurality of electric elements are formed between the second reinforcing plate 462 and the second support member 262 via the second waterproof member 482, the third waterproof member 483, and the fourth waterproof member 484, and are disposed in the second waterproof space 4821 having a closed roof shape that overcomes the discontinuous section generated by the stepped structure, and are therefore protected from moisture and / or foreign substances penetrating from the outside.

[0077] The waterproof structures (WP1, WP2) according to various embodiments of the present invention have an arrangement structure in which the plurality of waterproof members (481, 482, 483, 484) are attached to the reinforcement plates (461, 462) rather than to the rear surface of the display panel 430, thereby reducing damage to the display panel 430 (e.g., tearing due to adhesive force) and improving visibility during maintenance and repair of the electronic device 200. In addition, since the plurality of waterproof members (481, 482, 483, 484) are not directly attached to the digitizers (471, 472), deterioration of the waterproof function due to the coil pattern is reduced. In addition, since the electrical connection structure (e.g., the through path of the FPCB connection parts (4711, 4721, 4323)) of the digitizers (471, 472) and / or the display panel 430 is provided within the waterproof spaces (4811, 4821), exposure to external moisture and / or contamination by foreign substances is reduced.

[0078] FIG. 8b is a partial cross-sectional view of an electronic device showing an FPCB connector disposed through region 8b of FIG. 6 and region 8b of FIG. 7 according to various embodiments of the present invention.

[0079] 8b, an electronic device (e.g., electronic device 300 of FIG. 3) includes a first waterproof member 481 disposed between a first reinforcing plate 461 disposed under a first digitizer 471 and a first support member 261 of a first housing 210. According to an embodiment, the first waterproof member 481 includes a first waterproof space 4811 formed between the first support member 261 and the first reinforcing plate 461. According to an embodiment, the first digitizer 471 includes a through hole 4711a formed in a first metal sheet layer 4712 disposed between the first digitizer 471 and the first reinforcing plate 461, and a first FPCB connection part 4711 led out through a first through hole 4611 formed in the first reinforcing plate 461 and accommodated in the first waterproof space 4811. According to one embodiment, one end of the first FPCB connection part 4711 is electrically connected to the first digitizer 471 via solder (S), and the other end is electrically connected to the first board 271 disposed in the first space (e.g., the first space 2101 in FIG. 1a) of the first housing 210 after passing through the first member through hole 2611 formed in the first support member 261. In another embodiment, at least a portion of the first FPCB connection part 4711 is attached to the surface of the reinforcing plate 461 via a fourth adhesive member T4 within the first waterproof space 4811. Thus, the cable through path connecting the first digitizer 471 and the first board 271 is disposed in the first waterproof space 4811 formed via the first waterproof member 481, thereby preventing the inflow of external moisture and / or foreign substances. Although not shown, a second digitizer (e.g., second digitizer 472 of FIG. 8) is also electrically connected to a second substrate (e.g., second substrate 272 of FIG. 3) disposed in a second space (e.g., second space 2201 of FIG. 1a) of a second housing (e.g., second housing 220 of FIG. 1a) in substantially the same manner via a second waterproof space (e.g., second waterproof space 4821 of FIG. 8a) formed via a second waterproof structure (e.g., second waterproof structure WP2 of FIG. 8a).

[0080] FIG. 8c is a partial perspective view of the second housing illustrating a state in which a fourth waterproofing member is applied in region 8c of FIG. 7 according to various embodiments of the present invention.

[0081] 8c, the second housing 220 faces the second reinforcing plate (e.g., the second reinforcing plate 462 in FIG. 6) and includes a filler injection hole 2623 (e.g., a through hole) formed in the second support member 262 at a position corresponding to the space between the second waterproofing member (e.g., the second waterproofing member 482 in FIG. 7) and the third waterproofing member (e.g., the third waterproofing member 483 in FIG. 7). For example, the filler injection hole 2623 is formed at a position corresponding to the space between the second waterproofing member 482 attached to the second reinforcing plate 462 and the third waterproofing member (e.g., the third waterproofing member 484 in FIG. 7) attached to the cover member (e.g., the cover member 485 in FIG. 8a). According to an embodiment, the fourth waterproof member 484 is injected through the filler injection hole 2623 from the second space 2201 of the second housing 220 in a state where the second waterproof member 482 and the third waterproof member 483 are attached (e.g., in a state where the flexible display 230 is attached to the second housing 220). According to an embodiment, the fourth waterproof member 484 is applied in a liquid or semi-solid form through the needle 610 of the dispenser 600 after the needle 610 is partially inserted into the filler injection hole 2623, and then solidified. In this case, the solidified fourth waterproof member 484 connects the second waterproof member 482 and the third waterproof member 483, and is fixed to the second support member 262 and the space between the second waterproof member 482 and the third waterproof member 483 after hardening, thereby helping to form a sealed second waterproof space (e.g., the second waterproof space 4821 in FIG. 7).

[0082] FIG. 8d is a cross-sectional view of an electronic device including a flexible display taken along line 8d-8d of FIG. 6 according to various embodiments of the present invention.

[0083] In describing the electronic device 200 of FIG. 8d, components that are substantially the same as those in the electronic device 200 of FIG. 8a are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0084] 8d, the electronic device 200 includes at least one magnet (M1, M2) disposed in the first housing 210 and the second housing 220. According to an embodiment, the at least one magnet (M1, M2) includes a first magnet M1 disposed in the first housing 210 and a second magnet M2 disposed in the second housing 220. According to an embodiment, the first magnet M1 and the second magnet M2 are disposed in corresponding positions that react to magnetic forces relative to each other when the electronic device 200 is in a folded state, and help maintain the folded state via magnetic forces (e.g., attractive forces).

[0085] According to various embodiments, the electronic device 200 includes a first shielding member 491 for blocking the magnetic force of the first magnet M1 disposed in the first housing 210 from affecting the first digitizer 471 and / or the display panel 430, and a second shielding member 492 for blocking the magnetic force of the second magnet M2 disposed in the second housing 220 from affecting the second digitizer 472 and / or the display panel 430. According to one embodiment, if the first shielding member 491 overlaps the first waterproofing member 481 disposed in the first reinforcing plate 461, a step may be generated, causing a waterproof function to be lost. Therefore, the first shielding member 491 is disposed between the first digitizer 471 and the first support member 261 in an area where at least a portion of the first reinforcing plate 461 and the first metal sheet layer 4712 are removed to avoid the first waterproofing member 481 and accommodate the thickness of the first shielding member 491. According to an embodiment, the second shielding member 492 is disposed via a laminated structure in which the bent portion 432 is disposed in a region corresponding to the second housing 220. According to an embodiment, the second shielding member 492 is disposed in a region where the second reinforcing plate 462 and the second metal sheet layer 4722 are omitted, between the first adhesive member T1 that attaches the extension portion 4321 to the second reinforcing plate 462 and the second digitizer 472. For example, the thickness of the second shielding member 492 is formed to be the same as the combined thickness of the second reinforcing plate 462 and the second metal sheet layer 4722.

[0086] FIG. 9 is an enlarged view of area 9 of FIG. 6 in accordance with various embodiments of the present invention.

[0087] 9, the first waterproof space (2) 4812 formed through the first waterproof member 481 is disposed near the edge 481a (e.g., edge) of the first waterproof member 481 to correspond to the first support member (e.g., the module receiving hole (e.g., the module receiving hole 2612 in FIG. 7) of the first support member 261 in FIG. 7). This is because, when at least one electronic component disposed through the module receiving hole 2612 is a camera module and / or a sensor module, it is advantageous to configure a large screen as it is closer to the edge of the flexible display 230. In such a case, the distance from the first waterproof space (2) 4812 to the edge 481a of the first waterproof member 481 may be so narrow that it is difficult to implement a waterproof function.

[0088] According to various embodiments of the present invention, the first waterproofing member 481 includes a protrusion 481b having an extended distance (D) that protrudes from the edge 481a by a specified distance (ΔD). According to one embodiment, the first waterproofing member 481 has the protrusion 481b formed in a shape corresponding to the shape of the first waterproof space (2) 4812, thereby inducing a uniform distance (D) from the first waterproofing space (2) 4812 to the edge 481a, thereby helping to realize a stable waterproof function. According to one embodiment, when the first waterproofing space (2) 4812 is circular, the protrusion 481b is formed in a curved shape having a curvature corresponding thereto.

[0089] FIG. 10 is a cross-sectional view of an electronic device according to various embodiments of the present invention.
