The first side portion (211) and the third side portion (221) may face each other when the electronic device (201) is in a folded state.

[0053] In one embodiment, the electronic device (201) may include a recessed receiving portion (202) that receives a display (261) through a structural combination of a first housing (210) and a second housing (220). The receiving portion (202) may have substantially the same size as the display (261).

[0054] In one embodiment, at least a portion of the first housing (210) and the second housing (220) may be formed of a metallic or non-metallic material having any rigidity suitable for supporting the display (261).

[0055] In one embodiment, the electronic device (201) may include an audio output module (255) (e.g., audio output module (155)) disposed over at least a portion of the first surface (211).

[0056] In one embodiment, the first rear cover (240) can be disposed on the second side (212) of the first housing (210) and can have substantially rectangular edges. At least a portion of the edges of the first rear cover (240) can be surrounded by the first housing (210). The second rear cover (250) can be disposed on the fourth side (222) of the second housing (220) and can have substantially rectangular edges. At least a portion of the edges of the second rear cover (250) can be surrounded by the second housing (220).

[0057] In one embodiment, the first rear cover (240) and the second rear cover (250) may have substantially symmetrical shapes with respect to the folding axis (A). In another embodiment, the first rear cover (240) and the second rear cover (250) may have different shapes. In yet another embodiment, the first housing (210) and the first rear cover (240) may be formed integrally, and the second housing (220) and the second rear cover (250) may be formed integrally.

[0058] In one embodiment, the first housing (210), the second housing (220), the first rear cover (240), and the second rear cover (250) may be coupled to each other to provide a space in which various components of the electronic device (201) (e.g., a printed circuit board, an antenna module (197), a sensor module (176), or a battery (189)) may be placed. In one embodiment, at least one component may be visually exposed on the rear surface of the electronic device (201). For example, at least one component may be visually exposed through the first rear area (241) of the first rear cover (240). Here, the component may include a proximity sensor, a rear camera module, and / or a flash. In one embodiment, at least a portion of the sub-display (262) may be visually exposed through the second rear area (242) of the first rear cover (240).

[0059] In one embodiment, the display (261) may be disposed in a receiving portion (202) formed by a pair of housings (210, 220). For example, the display (261) may be disposed to occupy substantially most of the front surface of the electronic device (201). The front surface of the electronic device (201) may include an area where the display (261) is disposed, a portion (e.g., an edge area) of a first housing (210) adjacent to the display (261), and a portion (e.g., an edge area) of a second housing (220). The back surface of the electronic device (201) may include a first back cover (240), a portion (e.g., an edge area) of the first housing (210) adjacent to the first back cover (240), a second back cover (250), and a portion (e.g., an edge area) of the second housing (220) adjacent to the second back cover (250). In one embodiment, the display (261) may be a display in which at least some areas can be transformed into a flat or curved surface. In one embodiment, the display (261) may include a folding area (261c), a first area (261a) on a first side (e.g., upper) based on the folding area (261c), and a second area (261b) on a second side (e.g., lower) based on the folding area (261c). The first area (261a) may be located on a first side (211) of the first housing (210), and the second area (261b) may be located on a third side (221) of the second housing (220). However, the division of areas of the display (261) is exemplary, and the display (261) may be divided into a plurality of areas depending on the structure or function of the display (261). For example, as illustrated in FIG. 2A, the area of ​​the display (261) may be divided by a folding area (261c) extending parallel to the X-axis or a folding axis (A), but the area of ​​the display (261) may also be divided by another folding area (e.g., a folding area extending parallel to the Y-axis) or another folding axis (e.g., a folding axis parallel to the Y-axis).The above-described division of the display (261) into areas is merely a physical division by a pair of housings (210, 220) and a hinge structure. In reality, the display (261) can display substantially one screen through a pair of housings (210, 220) and a hinge structure. In one embodiment, the first area (261a) and the second area (261b) may have a substantially symmetrical shape with respect to the folding area (261c).

[0060] In one embodiment, the hinge cover (265) may be disposed between the first housing (210) and the second housing (220) and configured to cover the hinge structure. The hinge cover (265) may be hidden by at least a portion of the first housing (210) and the second housing (220) or exposed to the outside depending on the operating state of the electronic device (201). For example, as illustrated in FIG. 2A, when the electronic device (201) is in an unfolded state, the hinge cover (265) may be hidden by the first housing (210) and the second housing (220) and not exposed to the outside, and as illustrated in FIG. 2B, when the electronic device (201) is in a folded state, the hinge cover (265) may be exposed to the outside between the first housing (210) and the second housing (220). Meanwhile, when the electronic device (201) is in an intermediate state where the first housing (210) and the second housing (220) form an angle with each other, at least a portion of the hinge cover (265) may be exposed to the outside between the first housing (210) and the second housing (220). At this time, the area where the hinge cover (265) is exposed to the outside may be smaller than the exposed area of ​​the hinge cover (265) when the electronic device (201) is in a folded state. In one embodiment, the hinge cover (265) may have a curved surface.

[0061] In order to explain the operation of the electronic device (201) according to one embodiment, when the electronic device (201) is in an unfolded state (e.g., the state of the electronic device (201) of FIG. 2A), the first housing (210) and the second housing (220) may form a first angle (e.g., about 180 degrees) with respect to each other, and the first region (261a) and the second region (261b) of the display (261) may be oriented in substantially the same direction. The folding region (261c) of the display (261) may be on substantially the same plane as the first region (261a) and the second region (261b). In another embodiment, when the electronic device (201) is in an unfolded state, the first housing (210) and the second housing (220) may be folded in opposite directions so that the second side (212) and the fourth side (222) face each other by rotating the first housing (210) at a second angle (e.g., about 360 degrees) with respect to the second housing (220). On the other hand, when the electronic device (201) is in a folded state (e.g., the state of the electronic device (201) of FIG. 2B), the first housing (210) and the second housing (220) may face each other. The first housing (210) and the second housing (220) may form an angle of about 0 degrees to about 10 degrees, and the first region (261a) and the second region (261b) of the display (261) may face each other. At least a portion of the folding area (261c) of the display (261) may be transformed into a curved surface. Meanwhile, when the electronic device (201) is in an intermediate state, the first housing (210) and the second housing (220) may form a specific angle with each other. The angle (e.g., a third angle, approximately 90 degrees) formed by the first area (261a) and the second area (261b) of the display (261) with each other may be larger than the angle when the electronic device (201) is in a folded state and smaller than the angle when the electronic device (201) is in an unfolded state. At least a portion of the folding area (261c) of the display (261) may be transformed into a curved surface.At this time, the curvature of the surface of the folding area (261c) may be smaller than the curvature of the surface of the folding area (261c) when the electronic device (201) is in a folded state.

[0062] Meanwhile, various embodiments of the electronic device described in this document are not limited to the form factor of the electronic device (201) described with reference to FIGS. 2A and 2B, and can be applied to electronic devices of various form factors.

[0068] For example, each of the first plate (305a) and the second plate (305b) can be coupled to one of the first housing (e.g., the first housing (210) of FIGS. 2A and 2B) and the second housing (e.g., the first housing (220) of FIGS. 2A and 2B). The first plate (305a) and the second plate (305b) can support the first housing (310) and the second housing (320) and can rotate or move them.

[0069] In one embodiment, the hinge unit (330) may include a first hinge unit (330a) disposed on one side (e.g., in the +X direction) of the hinge plate (305) and a second hinge unit (330b) disposed on the other side (e.g., in the -X direction) of the hinge plate (305).

[0070] In one embodiment, the first hinge unit (330a) and the second hinge unit (330b) may be arranged symmetrically with respect to an axis (e.g., a Y-axis passing through the center of the hinge plate (305)) that is perpendicular to the folding axis (A). The first hinge unit (330a) and the second hinge unit (330b) may include a plurality of gears (335).

[0071] In one embodiment, the plurality of gears (335) may be arranged symmetrically with respect to the folding axis (A). For example, the first hinge unit (330a) may include two gears (335), and the two gears (335) may be arranged spaced apart from each other on both sides (e.g., in the +Y direction and the -Y direction) with respect to the folding axis (A). However, the arrangement of the plurality of gears (335) is not limited thereto, and the plurality of gears (335) may be arranged asymmetrically with respect to the folding axis (A) or in a direction perpendicular thereto (e.g., in the Y-axis or Z-axis direction).

[0072] In one embodiment, a plurality of gears (335) are inserted into a gear shaft (not shown) and rotate, and can rotate or move the first plate (305a) and the second plate (305b) relative to the center bar (306).

[0075] In one embodiment, the foldable glass (410), the polarizing layer (420), the display panel (430), the polymer layer (440), and the metal sheet layer (450) may be arranged to span at least a portion of a first surface (e.g., the first surface (211) of FIG. 2A) of a first housing (e.g., the first housing (210) of FIG. 2A) and a third surface (e.g., the third surface (221) of FIG. 2A) of a second housing (e.g., the second housing (220) of FIG. 2A).

[0076] In one embodiment, the foldable glass (410), the polarizing layer (420), the display panel (430), the polymer layer (440), the metal sheet layer (450), and the reinforcing plate (470) may each be attached to each other via an adhesive (or glue, adhesive layer) (P1, P2, P3, P4).

In addition, the foldable glass (410) can include a plurality of bridge structures arranged in an area corresponding to a foldable portion of the display (400) (e.g., the folding area (261c) of FIG. 2A). The plurality of bridge structures can provide improved flexibility to the display (400), assist in the bending motion of the foldable glass (410), and reinforce the rigidity of the display (400).

[0078] In one embodiment, the polarizing layer (420) can selectively transmit light generated from a light source of the display panel (430) and vibrating in a certain direction. According to one embodiment, the polarizing layer (420) may be formed integrally with the display panel (430).

[0079] In one embodiment, the display panel (430) may include a plurality of pixels and a wiring structure (e.g., an electrode pattern). The display panel (430) may be a foldable display panel. The display panel (430) may be supported by at least one layer (e.g., a metal sheet layer (450) and a reinforcing plate (470)) and may be folded or unfolded in conjunction with a hinge unit (e.g., a hinge assembly (303) of FIG. 3).

[0080] In one embodiment, the polymer layer (440) may be disposed under the display panel (430). The polymer layer (440) may provide a dark background to ensure visibility of the display panel (430) and may be formed of a cushioning material to cushion impact transmitted to the display (400). In one embodiment, to ensure waterproofing of the display (400), the polymer layer (440) may be omitted, or the polymer layer (440) may be disposed under the metal sheet layer (450).

[0081] In one embodiment, the metal sheet layer (450) may be formed into a shape that provides flexibility to the display (400). The metal sheet layer (450) may include at least one of SUS (steel use stainless) (e.g., STS (stainless steel)), Cu, Al, or metal CLAD (e.g., a laminated member in which SUS and Al are alternately arranged). Alternatively, the metal sheet layer (450) may include other alloy materials.

[0082] In one embodiment, the metal sheet layer (450) can help reinforce the rigidity of an electronic device (e.g., electronic device (101) of FIG. 1, electronic device (201) of FIGS. 2A and 2B), shield ambient noise, and dissipate heat emitted from surrounding heat-emitting components.

[0083] In one embodiment, the display (400) may include a digitizer (460). The digitizer (460) may be a detection member disposed under the metal sheet layer (450) and configured to receive input from an electronic pen (e.g., a stylus). For example, the digitizer (460) may include a coil member disposed on a dielectric substrate to detect a resonant frequency of an electromagnetic induction signal applied from the electronic pen.

[0084] In one embodiment, the display (400) may further include at least one functional member (not shown) disposed between the polymer layer (440) and the metal sheet layer (450), or under the metal sheet layer (450). For example, the functional member may include a graphite sheet for heat dissipation, a force touch FPCB, a fingerprint sensor FPCB, an antenna radiator for communication, or a conductive / non-conductive tape.

[0085] In one embodiment, an electronic device (e.g., electronic device (101) of FIG. 1, electronic device (201) of FIGS. 2A and 2B) may be disposed under a display (400) and may include a camera device (e.g., camera module (180) of FIG. 1) or at least one sensor module (e.g., sensor module (176) of FIG. 1) (e.g., an illuminance sensor, a proximity sensor, or a TOF sensor) that detects an external environment through the display (400).

[0086] In one embodiment, each of the polarizing layer (420), the display panel (430), the polymer layer (440), the metal sheet layer (450), the digitizer (460), and the reinforcing plate (470) may include a through hole (4201, 4301, 4401, 4501, 4601, 4701). However, the display panel (430) and / or the polarizing layer (420) may not require the through hole (4201, 4301) by controlling the transmittance of the corresponding area.

[0087] In one embodiment, the size of each of the through holes (4201, 4301, 4401, 4501, 4601, 4701) may be determined based on the type, size, and / or field of view of the camera device or sensor module, and the sizes of each of the through holes (4201, 4301, 4401, 4501, 4601, 4701) may be different from each other.

[0088] In one embodiment, the display (400) may include a rollable type display, a slidable type display, or an extensible type display whose display area can be changed.

The reinforcing plate (470) may be formed to support the entire area of ​​the display (400) as illustrated in FIG. 4. Alternatively, but not limited thereto, the reinforcing plate (470) may be formed to support at least a portion of two areas adjacent to the folding area of ​​the display (400).

[0090] FIG. 5 is a plan view illustrating the interior of an electronic device (500) according to one embodiment.

[0091] Referring to FIG. 5, an electronic device (500) according to an embodiment (e.g., the electronic device (101) of FIG. 1 or the electronic device (201) of FIGS. 2A and 2B) may include at least a portion of a first housing (510) (e.g., the first housing (210) of FIGS. 2A and 2B), a second housing (520) (e.g., the second housing (220) of FIGS. 2A and 2B), a display (400) (e.g., the display module (160) of FIG. 1 or the display (261) of FIG. 2A or the display (400) of FIG. 4), a hinge unit (530) (e.g., the hinge unit (330) of FIG. 3), a center bar (506) (e.g., the center bar (306) of FIG. 3), and a hinge plate (505) (e.g., the hinge plate (305) of FIG. 3).

[0092] Hereinafter, any content overlapping with the above will be omitted for explanation, and it is to be understood that, in the electronic device (500), some components and structures may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the embodiments described above may be combined in the electronic device (500) unless it is technically clearly impossible.

[0093] An electronic device (500) according to one embodiment may be a foldable electronic device (500). For example, the electronic device (500) may be folded or unfolded around a folding axis (A) (or hinge axis).

[0094] In one embodiment, the first housing (510) and the second housing (520) may form at least a portion of the exterior of the electronic device (500). The first housing (510) and the second housing (520) may accommodate electrical components of the electronic device (500) therein and protect the electrical components of the electronic device (500) from external impact or inflow of foreign substances.

[0095] For example, the first housing (510) may include a front side (e.g., a first side (211) in FIG. 2A) facing the front or display (400) direction (e.g., a +Z direction) of the electronic device (500), a back side (e.g., a second side (212) in FIGS. 2A and 2B) facing the opposite direction (e.g., a side in the -Z direction), and a side side (e.g., a first side portion (213) in FIGS. 2A and 2B) surrounding at least a portion of the space between the front and back sides.

[0096] For example, the second housing (520) may include a front side facing the front or display (400) of the electronic device (500) (e.g., the third side (221) in FIG. 2A), a back side facing in an opposite direction (e.g., the fourth side (222) in FIGS. 2A and 2B), and a side side surrounding at least a portion of the space between the front and back sides (e.g., the second side portion (223) in FIGS. 2A and 2B).

[0097] In one embodiment, the first housing (510) and the second housing (520) may include a conductive pattern or a conductive material that is connected to the interior of the electronic device (500). The conductive pattern or the conductive material may be connected to a processor (e.g., processor (120) of FIG. 1) or a communication module (e.g., communication module (190) of FIG. 1) of the electronic device (500) and may operate as an antenna structure (e.g., antenna module (197) of FIG. 1).

[0098] In one embodiment, the first housing (510) and the second housing (520) may be coupled to opposite sides (e.g., + / -Y direction) of the hinge unit (530) while the display (400) is connected to the hinge unit (530). The first housing (510) and the second housing (520) may be connected to the hinge unit (530) and may move relative to or away from each other by the hinge unit (530). Alternatively, the first housing (510) may be connected to the first area (401) of the display (400), and the second housing (520) may be connected to the second area (402) of the display (400), and the first area (401) and the second area (402) may be connected to the hinge unit (530), and the first area (401) and the second area (402) may be moved relative to or away from each other by the hinge unit (530).

[0099] In one embodiment, the angle or distance between the first housing (510) and the second housing (520) may vary depending on whether the electronic device (500) is in a flat state (or unfolding state), a folded state, or an intermediate state. For example, the unfolded state may be a state in which the first housing (510) and the second housing (520) are moved the furthest from each other. For example, the folded state may be a state in which the first housing (510) and the second housing (520) are moved the closest to each other. For example, the intermediate state may include all states between the unfolded state and the folded state.

[0100] In one embodiment, the first housing (510) and the second housing (520) may provide a space in which a display (400) is placed. The display (400) may be a foldable flexible display (400).

[0101] For example, the display (400) may include a first region (401) (e.g., the first region (261a) of FIG. 2A), a second region (402) (e.g., the second region (261b) of FIG. 2A), and a folding region (403) between the first region (401) and the second region (402) (e.g., the folding region (261c) of FIG. 2A).

[0102] In one embodiment, the first housing (510) may be positioned facing the first area (401) of the display (400) and may support the first area (401) of the display (400). The second housing (520) may be positioned facing the second area (402) of the display (400) and may support the second area (402) of the display (400).

[0103] In one embodiment, the hinge unit (530) may be disposed between the first housing (510) and the second housing (520) to connect the first housing (510) and the second housing (520). For example, the hinge unit (530) may include a first hinge unit (530a) (e.g., the first hinge unit (330a) of FIG. 3) and a second hinge unit (530b) (e.g., the second hinge unit (330b) of FIG. 3).

[0104] In one embodiment, the plurality of hinge units (530a, 530b) may be spaced apart in both directions (e.g., + / - X direction) along the folding axis (A). For example, as shown in FIG. 5, the first hinge unit (530a) and the second hinge unit (530b) may be spaced apart in both sides (e.g., + / - X direction) of the electronic device (500) along the folding axis (A). However, this is merely exemplary, and the number and arrangement of the plurality of hinge units (530a, 530b) are not limited thereto.

[0105] In one embodiment, the hinge unit (530) can be actuated to implement a folding or unfolding operation of the electronic device (500). The hinge unit (530) can operate between a folded state in which the first region (401) and the second region (402) face each other, and an unfolded state in which the first region (401) and the second region (402) do not face each other but are spaced apart and face substantially in the same direction. The hinge unit (530) can generate a detent force that allows a specific state of the electronic device (500) to be maintained.

[0106] For example, when the electronic device (500) is in a folded state, the hinge unit (530) can be driven to generate a force (e.g., a closing detent force) that maintains the electronic device (500) in the folded state.

[0107] For example, when the electronic device (500) is in an unfolded state, the hinge unit (530) can be driven to generate a force (e.g., an open detent force) that maintains the electronic device (500) in the unfolded state.

[0108] For example, when the electronic device (500) is in an intermediate state, the hinge unit (530) can generate a force (e.g., a free stop force) to maintain the electronic device (500) in the intermediate state.

[0109] In one embodiment, the center bar (506) may be positioned horizontally to the folding axis of the hinge unit (530) and facing the folding axis. The center bar (506) may reinforce the rigidity of the hinge unit (530) and absorb shock transmitted from the outside, thereby protecting the hinge unit (530) from external shock.

[0110] In one embodiment, a hinge plate (505) may be provided between the hinge unit (530) and the display (400). The hinge plate (505) may include a first plate (505a) (e.g., the first plate (305a) of FIG. 3) and a second plate (505b) (e.g., the second plate (305b) of FIG. 3).

[0111] In one embodiment, the first plate (505a) and the second plate (505b) may be respectively positioned on opposite sides (e.g., + / - Y direction) with respect to the center bar (506). The first plate (505a) may be connected to at least a portion of the first region (401) of the display (400) to support the first region (401). The second plate (505b) may be connected to at least a portion of the second region (402) of the display (400) to support the second region (402).

[0112] In one embodiment, each of the first plate (505a) and the second plate (505b) may be connected to a hinge unit (530). The first plate (505a) and the second plate (505b) may be driven to move together in conjunction with the operation of the hinge unit (530) and may assist the foldable operation of the first housing (510), the second housing (520), and / or the display (400).

[0113] FIG. 6a is a schematic diagram illustrating a cross-section of an electronic device (500) according to one embodiment, and FIG. 6b is a schematic diagram illustrating a cross-section of an electronic device (500) according to one embodiment.

[0114] Specifically, FIG. 6a is a cross-sectional view of a portion of an electronic device (500) viewed along the BB' line of FIG. 5, and FIG. 6b is an enlarged view of a portion of area C of FIG. 6a.

[0115] Referring to FIGS. 6A and 6B, an electronic device (500) according to one embodiment may include at least some of a connecting member (551), a first member (553), and a second member (555).

[0116] Hereinafter, any content overlapping with the above will be omitted for explanation, and it is to be understood that, in the electronic device (500), some components and structures may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the embodiments described above may be combined in the electronic device (500) unless it is technically clearly impossible.

[0117] In one embodiment, a shield layer (455) may be provided between the metal sheet layer (450) of the display (400) and the fourth adhesive (P4). The shield layer (455) may protect the metal sheet layer (450) and absorb impact transmitted to the metal sheet layer (450). For example, the shield layer (455) may prevent foreign substances such as moisture, sand, or dust from entering the metal sheet layer (450).

[0118] In one embodiment, the shield layer (455) may be arranged adjacent to the connecting member (551) in a lateral direction (e.g., in the XY plane direction). The shield layer (455) may be made of thermoplastic polyurethane (TPU).

[0119] In one embodiment, a center bar (506) (e.g., center bar (306) of FIG. 3) may be positioned between a hinge unit (530) and a folding area (403) of a display (400). A hinge plate (505) (e.g., hinge plate (305) of FIG. 3) may include a first plate (505a) (e.g., first plate (305a) of FIG. 3) and a second plate (505b) (e.g., second plate (305b) of FIG. 3) that are positioned on opposite sides (e.g., +Y direction and -Y direction) with respect to the center bar (506), respectively.

[0120] In one embodiment, an open area (508) may be formed between the center bar (506) and the hinge plate (505). For example, an open area (508) may be formed between the center bar (506) and the first plate (505a), and between the center bar (506) and the second plate (505b), respectively.

[0121] In one embodiment, some components (e.g., gears, cam members, and / or springs) of a hinge unit (e.g., hinge unit (530) of FIG. 5) may be disposed in the open area (508). Alternatively, some components of the hinge unit (530) may be disposed below the open area (508), and when the hinge unit (530) is in a folded or intermediate state, some components of the hinge unit (530) may be located in the open area (508).

[0122] In one embodiment, the connecting member (551) may be positioned facing the folding area (e.g., the folding area (403) of FIG. 5) of the display (400). For example, the connecting member (551) may be positioned facing the metal sheet layer (450) of the display (400), facing the folding area (430) of the display (400) and an area adjacent thereto.

[0123] In one embodiment, the connecting member (551) may be bonded to the step member (571, 572). The step member (571, 572) may include an adhesive material having adhesive properties. For example, at least a portion of one side (e.g., a side in the +Z direction) of the connecting member (551) may be arranged to face the metal sheet layer (450) of the display (400), and at least a portion of the other side (e.g., a side in the -Z direction) of the connecting member (551) may be bonded to the step member (571, 572).

[0124] In one embodiment, the connecting member (551) can prevent foreign substances such as moisture, sand, or dust from entering the metal sheet layer (450) of the display (400). The connecting member (551) can be made of the same material as the shield layer (455), for example, thermoplastic polyurethane (TPU).

[0125] In one embodiment, the first member (553) and the second member (555) may be disposed between the hinge plate (505) and the display (400). For example, the first member (553) and the second member (555) may directly or indirectly connect the hinge plate (505) and the display (400). The first member (553) and the second member (555) may be bonded to the display (400) or the hinge plate (505) via at least one adhesive layer (561, 563) made of an adhesive.

[0126] In one embodiment, the first member (553) and the second member (555) may be disposed on the lower side (e.g., in the -Z direction) of the metal sheet layer (450) of the display (400). For example, the first member (553) may be disposed between the first area (e.g., the first area (401) of FIG. 5) of the display (400) and the first plate (505a). The second member (555) may be disposed between the second area (e.g., the second area (402) of FIG. 5) of the display (400) and the second plate (505b).

[0127] In one embodiment, the first member (553) and the second member (555) may be formed of a material having high rigidity and excellent durability. For example, each of the first member (553) and the second member (555) may be formed of a material including at least one of carbon fiber reinforced plastics (CFRP), glass fiber reinforced plastics (GFRP), and aramid fiber reinforced polymer (AFRP). Alternatively, for example, the first member (553) and the second member (555) may be formed of SUS (steel use stainless) (e.g., STS (stainless steel)), Cu alloy, or Al alloy.

[0128] In one embodiment, the first member (553) and the second member (555) may be arranged so that at least a portion of the connection member (551) overlaps with the hinge plate (505) when the hinge unit (530) is unfolded, based on the direction in which the hinge plate (505) is viewed from the display (400).

[0129] For example, as illustrated in FIG. 6b, one end of the first member (553) (e.g., the end in the -Y direction) and one end of the second member (555) (e.g., the end in the +Y direction) may be arranged to face the lower surface (e.g., the surface in the -Z direction) of the connecting member (551).

[0130] In one embodiment, the first member (553) and the second member (555) are arranged to extend to a position facing the connecting member (551) facing the folding area (403) of the display (400), thereby absorbing shock transmitted from the folding area (403) of the display (400). In addition, the first member (553) and the second member (555) can reinforce the rigidity and durability of the folding area (403) of the display (400), and improve the connectivity of components of the electronic device (500).

[0131] In one embodiment, the electronic device (500) can cover the open area (508) through the first member (553) and the second member (555). The first member (553) and the second member (555) can reduce the area of ​​the open area (508) that is not exposed or is exposed toward the display (400).

[0132] In one embodiment, the first member (553) and the second member (555) can make the folding area (403) of the display (400) flat when the electronic device (500) is in an unfolded state, thereby providing improved surface quality.

[0133] For example, when viewing the electronic device (500) from the outside, the folding area (403) may appear curved due to the configuration (e.g., gear, cam member, and / or spring) of the hinge unit (530) provided in the open area (508), and the surface quality of the display (400) may be degraded.

[0134] The first member (553) and the second member (555) according to one embodiment of the present document can cover the open area (508). The first member (553) and the second member (555) can make the folding area (403) flat, improve the visibility of the electronic device (500), and provide improved surface quality of the display (400).

[0135] In one embodiment, the first member (553) may be arranged so as to be non-overlapping with the center bar (506) in a direction (e.g., -Z direction) when the hinge unit (530) is in an unfolded state (or unfolded state) when looking at the hinge plate (505) from the display (400). In addition, the second member (555) may be arranged so as to be non-overlapping with the center bar (506) in a direction (e.g., -Z direction) when looking at the hinge plate (505) from the display (400) when the hinge unit (530) is in an unfolded state (or unfolded state).

[0136] For example, as illustrated in FIG. 6B, the center bar (506) may form a width region (D), which is a virtual space extending in a vertical direction (e.g., +Z direction) or a front direction. The first member (553) and the second member (555) may be arranged so as to not overlap the width region (D). Alternatively, the first member (553) and the second member (555) may extend to an area that does not exceed the width region (D). However, the first member (553) and the second member (555) are not limited thereto, and the first member (553) and the second member (555) according to one embodiment may be arranged so that at least a portion of the area overlaps the width region (D).

[0137] In one embodiment of the present document, the first member (553) and the second member (555) are arranged non-overlapping with the center bar (506), so that when the hinge unit (530) is folded, the first member (553) and the second member (555) do not collide with or come into contact with other components.

[0138] In one embodiment, the electronic device (500) may include a first adhesive layer (561) and a second adhesive layer (563). The first adhesive layer (561) and the second adhesive layer (563) may be made of a material that is the same as or similar to the adhesives (P1, P2, P3, P4) of the display (400). For example, the first adhesive layer (561) and the second adhesive layer (563) may include at least one of an optical clear adhesive (OCA), a pressure sensitive adhesive (PSA), a heat-reactive adhesive, a general adhesive, or a double-sided tape.

[0139] In one embodiment, the first adhesive layer (561) can connect the first member (553) and the second member (555) to the display (400). The first adhesive layer (561) can be disposed adjacent to the connection member (551) in a lateral direction (e.g., + / -Y direction). For example, the first adhesive layer (561) can be disposed on the upper surfaces (e.g., the surface in the +Z direction) of the first member (553) and the second member (555) to surround the connection member (551) in a lateral direction of the connection member (551).

[0140] In one embodiment, the second adhesive layer (563) can connect the first member (553) and the second member (555) to the hinge plate (505). For example, the second adhesive layer (563) can be adhered to the lower surfaces (e.g., the -Z direction surfaces) of the first member (553) and the second member (555).

[0141] In one embodiment, the first adhesive layer (561) and the second adhesive layer (563) may have different thicknesses. For example, the second adhesive layer (563) may be relatively thicker than the first adhesive layer (561).

[0142] In one embodiment, the second adhesive layer (563) can connect the first plate (505a) and the first member (553), and can connect the second plate (505b) and the second member (555). Since the second adhesive layer (563) must transmit the force transmitted from the first plate (505a) and the second plate (505b) to the first member (553) and the second member (555), respectively, it needs to be structurally stable so that slipping does not occur due to the operation of the hinge unit (530), and thus, it can be relatively thicker compared to the first adhesive layer (561). For example, the second adhesive layer (563) can have a thickness between 1.5 and 2.5 times the thickness of the first adhesive layer (561).

[0143] In one embodiment, when the second adhesive layer (563) is less than 1.5 times the thickness of the first adhesive layer (561), slip may occur due to the operation of the hinge unit (530). In addition, when the second adhesive layer (563) is more than 2.5 times the thickness of the first adhesive layer (561), the thickness of the electronic device (500) may increase, and the space efficiency of the electronic device (500) may decrease.

[0144] In one embodiment of the present document, the second adhesive layer (563) can provide space efficiency of the electronic device (500) and prevent slippage of the operation of the hinge unit (530) by having a thickness of between 1.5 and 2.5 times the thickness of the first adhesive layer (561), preferably 2 times the thickness. For example, the first adhesive layer (561) can have a thickness of 50 μm, and the second adhesive layer (563) can have a thickness of 100 μm.

[0145] In one embodiment, the first adhesive layer (561) and the second adhesive layer (563) may have different storage modulus. For example, the first adhesive layer (561) may have a relatively large storage modulus compared to the second adhesive layer (563).

[0146] In one embodiment, the first adhesive layer (561) needs to provide stable fixing force with little deformation to connect the first member (553) and the second member (555) to the display (400). Since a larger storage modulus means less deformation, the first adhesive layer (561) may have a relatively larger storage modulus compared to the second adhesive layer (563). For example, the first adhesive layer (561) may have a storage modulus that is between 7 and 12 times the storage modulus of the second adhesive layer (563).

[0147] In one embodiment, if the first adhesive layer (561) is less than 7 times the storage elastic modulus of the second adhesive layer (563), the adhesive stability of the first adhesive layer (561) may be reduced. In addition, if the first adhesive layer (561) is more than 12 times the storage elastic modulus of the second adhesive layer (563), the flexibility may be reduced and the first adhesive layer (561) may be detached or separated as the hinge motion is repeated.

[0148] In one embodiment of the present document, the first adhesive layer (561) can provide adhesive stability of the first adhesive layer (561) by having a storage modulus between 7 and 12 times that of the second adhesive layer (563), preferably by having a storage modulus of 10 times that of the second adhesive layer (563).

[0149] For example, the first adhesive layer (561) may have a storage modulus of elasticity of 700 to 1,560 kPa, and the second adhesive liner may have a storage modulus of elasticity of 100 to 130 kP. Alternatively, for example, the first adhesive layer (561) may have a storage modulus of elasticity of 1,000 to 1,170 kPa, and the second adhesive liner may have a storage modulus of elasticity of 100 to 130 kP.

[0150] In one embodiment, the electronic device (500) may further include a first step member (571) and a second step member (572). The first step member (571) may be provided in a portion of the first member (553) facing the first plate (505a). The second step member (572) may be provided in a portion of the second member (555) facing the second plate (505b).

[0151] For example, the first step member (571) may be bonded to a portion of the first member (553) that faces the connecting member (551). Alternatively, the first step member (571) may be bonded to a portion of the connecting member (551) that faces the first member (553).

[0152] For example, the second step member (572) may be bonded to a portion of the second member (555) that faces the connecting member (551). Alternatively, the second step member (572) may be bonded to a portion of the connecting member (551) that faces the second member (555).

[0153] In one embodiment, the first step member (571) and the second step member (572) may be formed of an adhesive material having adhesive strength. For example, the first step member (571) and the second step member (572) may include at least one of an optical clear adhesive (OCA), a pressure sensitive adhesive (PSA), a heat-reactive adhesive, a general adhesive, or a double-sided tape.

[0154] In one embodiment, the connecting member (551) can be connected to the first member (553) and the second member (555) via the first step member (571) and the second step member (572). For example, one side (e.g., the side in the +Z direction) of the first step member (571) can be bonded to the connecting member (551), and the other side (e.g., the side in the -Z direction) can be bonded to the first member (553). For example, one side (e.g., the side in the +Z direction) of the second step member (572) can be bonded to the connecting member (551), and the other side (e.g., the side in the -Z direction) can be bonded to the second member (555).

[0155] In one embodiment, the sum of the thickness of either the first step member (571) or the second step member (572) and the thickness of the connecting member (551) may be equal to the thickness of the first adhesive layer (561). For example, when the thickness of the first adhesive layer (561) is 50 μm, the thickness of the first step member (571) or the second step member (572) may be 16 μm, and the thickness of the connecting member (551) may be 34 μm.

[0156] In one embodiment of the present document, the first step member (571) and the second step member (572) can prevent the first member (553) and the second member (555) extending toward the connecting member (551) from contacting or colliding with the connecting member (551) according to hinge actuation, and can absorb shock transmitted from the outside.

[0157] In one embodiment of the present document, each of the first step member (571) and the second step member (572) can fill a void provided between the first member (553) and the second member (555) and the connecting member (551). In addition, the first step member (571) and the second step member (572) can absorb shock transmitted through the connecting member (551), the first member (553), or the second member (555), and can reinforce the rigidity and durability of the electronic device (500).

[0158] FIG. 7A is a schematic diagram illustrating a cross-section of an electronic device (500) according to an embodiment, and FIG. 7B is a schematic diagram illustrating a cross-section of an electronic device (500) according to an embodiment. Specifically, FIG. 7A is a cross-sectional view of the inside of the electronic device (500) taken along the line BB' of FIG. 5, and FIG. 7B is an enlarged view illustrating the area C' of FIG. 7A.

[0159] Hereinafter, any content overlapping with the above will be omitted for explanation, and it is to be understood that, in the electronic device (500), some components and structures may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the embodiments described above may be combined in the electronic device (500) unless it is technically clearly impossible.

[0160] Referring to FIGS. 7A and 7B, an electronic device (500) according to one embodiment may further include a third step member (581) and a fourth step member (582).

[0161] In one embodiment, the third step member (581) may be provided in a portion of the first member (553) facing the first plate (505a). The fourth step member (582) may be provided in a portion of the second member (555) facing the second plate (505b).

[0162] For example, the third step member (581) may be bonded to a surface of the first member (553) that faces the first plate (505a). Alternatively, the third step member (581) may be bonded to a surface of the first plate (505a) that faces the first member (553).

[0163] For example, the fourth step member (582) may be bonded to a surface of the second member (555) that faces the second plate (505b). Alternatively, the fourth step member (582) may be bonded to a surface of the second plate (505b) that faces the second member (555).

[0164] In one embodiment, the thickness of either the third step member (581) or the fourth step member (582) may be the same as the thickness of the second adhesive layer (563). For example, when the thickness of the second adhesive layer (563) is 100 μm, the thicknesses of the third step member (581) and the fourth step member (582) may be 100 μm.

[0165] In one embodiment of the present document, the third step member (581) and the fourth step member (582) can prevent the first member (553) and the second member (555) extending toward the connecting member (551) from contacting or colliding with the first plate (505a) and the second plate (505b) according to hinge driving, and can absorb shock transmitted from the outside.

[0166] In one embodiment of the present document, each of the third step member (581) and the fourth step member (582) can fill the empty space provided between the first member (553) and the second member (555) and the first plate (505a) and the second plate (505b), respectively. In addition, the third step member (581) can absorb the impact transmitted through the first plate (505a) or the first member (553) to reinforce the rigidity and durability of the electronic device (500), and the fourth step member (582) can absorb the impact transmitted through the second plate (505b) or the second member (555) to reinforce the rigidity and durability of the electronic device (500).

[0167] FIG. 8a is a schematic diagram illustrating a folded state of an electronic device (500) according to one embodiment, and FIG. 8b is a schematic diagram illustrating an unfolded state of an electronic device (500) according to one embodiment.

[0168] Specifically, FIGS. 8A and 8B are schematic diagrams illustrating a portion of an electronic device (500) to explain the arrangement of the first member (553) and the second member (555) in an unfolded state and a folded state.

[0169] Referring to FIGS. 8A and 8B, the arrangement of the first member (553) and the second member (555) in a folded state of the electronic device (500) according to one embodiment can be confirmed.

[0170] Hereinafter, any content overlapping with the above will be omitted for explanation, and it is to be understood that, in the electronic device (500), some components and structures may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the embodiments described above may be combined in the electronic device (500) unless it is technically clearly impossible.

[0171] In one embodiment, in a state where the hinge unit (e.g., hinge unit (530) of FIG. 5) of the display (400) does not face each other and is unfolded (e.g., the display (400) state of the dotted line of FIG. 8), the first member (553) and the second member (555) may be arranged so as not to overlap the center bar (506).

[0172] In one embodiment, when the hinge unit (530) is driven into a folded state (e.g., the display (400) state of the solid line in FIG. 8) in which the first area (401) and the second area (402) of the display (400) face each other, the first member (553) and the second member (555) can move without colliding with other components including the center bar (506).

[0173] In one embodiment, the first member (553) can be actuated to move by being connected to the first region (401) of the display (400) through the first adhesive layer (561). The second member (555) can be actuated to move by being connected to the second region (402) of the display (400) through the first adhesive layer (561).

[0174] In one embodiment, each of the first member (553) and the second member (555) may be connected to the first region (401) and the second region (402), respectively, and may be at risk of contacting or colliding with the center bar (506) or other components while moving.

[0175] According to one embodiment of the present document, the first member (553) and the second member (555) can prevent collision of the first member (553) and the second member (555) through the extension length and arrangement design as shown in FIG. 8, and can provide stability of the electronic device (500) according to the operation of the hinge unit (530).
