For example, the third camera (243) may be disposed inside the first housing (210) and at least a portion thereof may be visible through the first front surface (211) of the first housing (210). In another example, the third camera (243) may be disposed inside the first housing (210) and at least a portion thereof may be visible through the first display area (231) of the display (230). The first display area (231) of the display (230) may include at least one opening (not shown) that overlaps the third camera (243) when the display (230) is viewed from above. The third camera (243) may acquire an image based on receiving light from the outside of the display (230) through the at least one opening.

[0048] According to one embodiment, the second camera (242) and the third camera (243) may be positioned below the display (230) (e.g., toward the inside of the first housing (210) or the inside of the second housing (220). For example, the second camera (242) and the third camera (243) may be under-display cameras (UDCs). When the second camera (242) and the third camera (243) are under-display cameras, an area of ​​the display (230) corresponding to the respective positions of the second camera (242) and the third camera (243) may not be an inactive area. For example, when the second camera (242) and the third camera (243) are under-display cameras, an area of ​​the display (230) corresponding to the respective positions of the second camera (242) and the third camera (243) may have a lower pixel density than a pixel density of another area of ​​the display (230). The inactive area of ​​the display (230) may refer to, for example, an area of ​​the display (230) that does not include pixels or does not emit light outside of the electronic device (101). As another example, the second camera (242) and the third camera (243) may be punch-hole cameras. When the second camera (242) and the third camera (243) are punch-hole cameras, an area of ​​the display (230) corresponding to the respective positions of the second camera (242) and the third camera (243) may be an inactive area. For example, when the second camera (242) and the third camera (243) are punch-hole cameras, an area of ​​the display (230) corresponding to the respective positions of the second camera (242) and the third camera (243) may include an opening that does not include pixels.

[0049] According to one embodiment, the hinge structure (250) can rotatably connect the first housing (210) and the second housing (220). The hinge structure (250) can be disposed between the first housing (210) and the second housing (220) of the electronic device (101) so that the electronic device (101) can be bent, curved, or folded. For example, the hinge structure (250) can be disposed between a portion of the first side (213) and a portion of the second side (223) that face each other. The hinge structure (250) can change the electronic device (101) into an unfolding state in which the first front surface (211) of the first housing (210) and the second front surface (221) of the second housing (220) face substantially the same direction, or into a folding state in which the first front surface (211) and the second front surface (221) face each other. When the electronic device (101) is in a folding state, the first housing (210) and the second housing (220) can be folded or overlapped by facing each other.

[0050] According to one embodiment, when the electronic device (101) is in a folded state, the direction in which the first front surface (211) faces and the direction in which the second front surface (221) faces may be different from each other. For example, when the electronic device (101) is in a folded state, the direction in which the first front surface (211) faces and the direction in which the second front surface (221) faces may be opposite to each other. For another example, when the electronic device (101) is in a folded state, the direction in which the first front surface (211) faces and the direction in which the second front surface (221) faces may be inclined with respect to each other. When the direction in which the first front surface (211) faces is inclined with respect to the direction in which the second front surface (221) faces, the first housing (210) may be inclined with respect to the second housing (220). However, the present invention is not limited thereto. For example, in the folded state of the electronic device (101), the first rear surface (212) of the first housing (210) may face the second rear surface (222) of the second housing (220). When the first rear surface (212) and the second rear surface (222) face each other in the folded state of the electronic device (101), the direction in which the first front surface (211) faces and the direction in which the second front surface (221) faces may be opposite to each other. When the first rear surface (212) and the second rear surface (222) face each other in the folded state of the electronic device (101), the display (230) may be visible from the outside in the folded state of the electronic device (101).

[0051] According to one embodiment, the electronic device (101) may be foldable based on a folding axis (f). The folding axis (f) may refer to a virtual line extending through the hinge cover (251) in a direction substantially parallel to the longitudinal direction of the electronic device (101) (e.g., d1 in FIGS. 2A and 2B), but is not limited thereto. For example, the folding axis (f) may be a virtual line extending in a direction substantially perpendicular to the longitudinal direction of the electronic device (101) (e.g., d2 in FIGS. 2A and 2B). When the folding axis (f) extends in a direction substantially perpendicular to the longitudinal direction of the electronic device (101), the hinge structure (250) may extend in a direction parallel to the folding axis (f) to connect the first housing (210) and the second housing (220). The first housing (210) and the second housing (220) may be rotatable by a hinge structure (250) extending in a direction substantially perpendicular to the longitudinal direction of the electronic device (101).

[0052] According to one embodiment, the hinge structure (250) may include a hinge cover (251), a first hinge plate (252), a second hinge plate (253), and a hinge module (254). The hinge cover (251) may surround internal components of the hinge structure (250) and form an outer surface of the hinge structure (250). According to one embodiment, the hinge cover (251) surrounding the hinge structure (250) may be at least partially exposed to the outside of the electronic device (101) through a space between the first housing (210) and the second housing (220) when the electronic device (101) is in a folded state. According to an embodiment, when the electronic device (101) is in an unfolded state, the hinge cover (251) may be covered by the first housing (210) and the second housing (220) and may not be exposed to the outside of the electronic device (101). According to one embodiment, the hinge structure (250) may be disposed between the housing (200) including at least partially the first housing (210) and the second housing (220) and the display (230), but is not limited thereto.

[0053] According to one embodiment, the first hinge plate (252) and the second hinge plate (253) may be coupled to the first housing (210) and the second housing (220), respectively, thereby rotatably connecting the first housing (210) and the second housing (220). For example, the first hinge plate (252) may be coupled to the first bracket (215) of the first housing (210), and the second hinge plate (253) may be coupled to the second bracket (227) of the second housing (220). As the first hinge plate (252) and the second hinge plate (253) are coupled to the first bracket (215) and the second bracket (227), respectively, the first housing (210) and the second housing (220) can be rotated according to the rotation of the first hinge plate (252) and the second hinge plate (253).

[0054] The hinge module (254) can rotate the first hinge plate (252) and the second hinge plate (253). For example, the hinge module (254) can rotate the first hinge plate (252) and the second hinge plate (253) about the folding axis (f) by including gears that are interlocked with each other and can rotate. According to one embodiment, the hinge module (254) can be a plurality of pieces. For example, the plurality of hinge modules (254) can be arranged spaced apart from each other at both ends of the first hinge plate (252) and the second hinge plate (253), respectively.

[0055] For example, the first hinge module (254a) may be spaced apart from the second hinge module (254b). For example, the second hinge module (254b) may be coupled to the third hinge module (254c). A flexible printed circuit board (263) may be at least partially disposed in the space between the first hinge module (254a) and the second hinge module (254b). The flexible printed circuit board (263) may connect the first printed circuit board (261) and the second printed circuit board (262) through the space between the first hinge module (254a) and the second hinge module (254b).

[0056] In one embodiment, the hinge structure (250) may include a buffer member (255). For example, the buffer member (255) may face the display (230). For example, the buffer member (255) may support a deformable area of ​​the display (230) (e.g., the third display area (233)), thereby reducing damage to the display (230). For example, the buffer member (255) may be attached to the display (230), thereby reducing damage to the display (230) as the hinge structure (250) operates.

[0057] In one embodiment, the first housing (210) may include a first bracket (215) and a first cover (216), and the second housing (220) may include a second bracket (227) and a second cover (228). The first bracket (215) may support components within the first housing (210). The first cover (216) may at least partially cover the components within the first housing (210). The first bracket (215) may define the first housing (210) by being coupled with the first cover (216). The first cover (216) may define a portion of an outer surface of the first housing (210). The second bracket (227) may support components within the second housing (220). The second cover (228) can at least partially cover the components within the second housing (220). The second bracket (227) can define the second housing (220) by being coupled with the second cover (228). The second cover (228) can define a portion of an outer surface of the second housing (220). For example, the display (230) can be disposed on one side of the first bracket (215) and one side of the second bracket (227). The first cover (216) can be disposed on the other side of the first bracket (215) opposite the one side of the first bracket (215). The second cover (228) can be disposed on the other side of the second bracket (227) opposite the one side of the second bracket (227). The sub display panel (235) can be placed between the second bracket (227) and the second cover (228).

[0058] In one embodiment, a portion of the first bracket (215) may be surrounded by the first side (213), and a portion of the second bracket (227) may be surrounded by the second side (223). For example, the first bracket (215) may be formed integrally with the first side (213), and the second bracket (227) may be formed integrally with the second side (223). In another example, the first bracket (215) may be formed separately from the first side (213), and the second bracket (227) may be formed separately from the second side (223).

According to one embodiment, at least one electronic component (260) may include a first printed circuit board (261), a second printed circuit board (262), a flexible printed circuit board (263), a battery (264) (e.g., the battery (189) of FIG. 1), and / or an antenna (265) (e.g., the antenna module (197) of FIG. 1). The first printed circuit board (261) and the second printed circuit board (262) may each form an electrical connection between components within the electronic device (101). For example, components for implementing the overall function of the electronic device (101) (e.g., the processor (120) of FIG. 1) may be arranged on the first printed circuit board (261), and electronic components for implementing some functions of the first printed circuit board (261) may be arranged on the second printed circuit board (262). For another example, components for the operation of a sub-display panel (235) disposed on the second rear surface (222) may be disposed on the second printed circuit board (262).

[0060] According to one embodiment, the first printed circuit board (261) may be disposed within the first housing (210). For example, the first printed circuit board (261) may be disposed on one surface of the first bracket (215). According to one embodiment, the second printed circuit board (262) may be disposed within the second housing (220). For example, the second printed circuit board (262) may be spaced apart from the first printed circuit board (261) and disposed on one surface of the second bracket (227). A flexible printed circuit board (263) may connect the first printed circuit board (261) and the second printed circuit board (262).

[0065] According to one embodiment, the hinge structure (250) can rotatably connect the first housing (210) and the second housing (220). For example, referring to FIGS. 2A to 2C together, the hinge structure (250) can provide a plurality of states, including a folded state and an unfolded state, of the electronic device (101) by rotatably connecting the first housing (210) and the second housing (220). For example, the hinge structure (250) can at least partially overlap the first housing (210) and / or the second housing (220). For example, the hinge structure (250) can be at least partially disposed between the first housing (210) and the second housing (220). For example, the hinge structure (250) may be configured to deform at least a portion (e.g., the third display area (233) of FIG. 2A) of a display (e.g., the display (230) of FIG. 2A) by rotatably connecting the first housing (210) and the second housing (220). For example, the hinge structure (250) may provide a folding axis (f) so that the first housing (210) can rotate relative to the second housing (220).

A second printed circuit board (320) may be disposed within the second housing (220) and may be spaced apart from the first printed circuit board (310). For example, the first printed circuit board (310) may be fastened to the first housing (210). The second printed circuit board (320) may be separated from the first printed circuit board (310) by being fastened to the second housing (220). For example, electronic components within the first housing (210) may be mounted on the first printed circuit board (310). Other electronic components within the second housing (220) that are spaced apart from the electronic components within the first housing (210) may be mounted on the second printed circuit board (320). For example, the first printed circuit board (310) and / or the second printed circuit board (320) may be equipped with a processor (e.g., the processor (120) of FIG. 1), a memory (e.g., the memory (130) of FIG. 1), and / or an interface (e.g., the interface (177) of FIG. 1). The processor may include, for example, one or more of a central processing unit, an application processor, a graphics processing unit, an image signal processor, a sensor hub processor, or a communication processor. The memory may include, for example, a volatile memory (e.g., the volatile memory (132) of FIG. 1) or a nonvolatile memory (e.g., the nonvolatile memory (134) of FIG. 1). The interface may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, and / or an audio interface. The interface may electrically or physically connect the electronic device (101) to an external electronic device and may include a USB connector, an SD card / MMC (multimedia card) connector, or an audio connector.The electronic device (101) may require a structure that connects the first printed circuit board (310) and the second printed circuit board (320) to electrically connect at least some of the electronic components within the first housing (210) with at least some of the other electronic components within the second housing (220).

[0067] In one embodiment, the flexible printed circuit board (330) can connect the first printed circuit board (310) and the second printed circuit board (320) by extending from the first printed circuit board (310) across the hinge structure (250) to the second printed circuit board (320). For example, the flexible printed circuit board (310) can electrically connect the first printed circuit board (310) and the second printed circuit board (320) by being coupled to the first printed circuit board (310) and the second printed circuit board (320). For example, at least a portion of the flexible printed circuit board (330) (e.g., the first connector (331)) can be disposed within the first housing (210) to be connected to the first printed circuit board (310). For example, at least a portion of the flexible printed circuit board (330) (e.g., the fourth connector (334)) may be disposed within the second housing (220) to be connected to the second printed circuit board (320). For example, the flexible printed circuit board (330) may include a rigid flexible printed circuit board. The flexible printed circuit board (330) may be referred to as a CTC (connector to connector) FPCB in that it connects the first printed circuit board (310) and the second printed circuit board (320), but is not limited thereto.

[0068] For example, at least a portion of the flexible printed circuit board (330) (e.g., the second connector (332)) may be disposed on the hinge structure (250) to electrically connect the first printed circuit board (310) and the second printed circuit board (320). It should be understood that when an element is referred to as being "on" another element, this may mean directly on the other element or there may be intervening elements between them. For example, within the present disclosure, "B disposed on A" may refer to "B disposed over A." For example, within the present disclosure, "B disposed on A" may refer to "B facing A and spaced apart from A." For example, “a flexible printed circuit board (330) disposed on a hinge structure (250)” may mean “a flexible printed circuit board (330) in contact with the hinge structure (250).” For example, “a flexible printed circuit board (330) disposed on a hinge structure (250)” may mean “a flexible printed circuit board (330) facing the hinge structure (250) and spaced apart from the hinge structure (250).” For example, the flexible printed circuit board (330) may overlap at least a portion of the hinge structure (250) (e.g., the mounting portion (383)) when viewed from above (e.g., when viewed in the -z direction). For example, a flexible printed circuit board (330) may extend from inside the first housing (210) across the hinge structure (250) into inside the second housing (220) to connect the first printed circuit board (310) and the second printed circuit board (320).The electronic device (101) may be configured to include a flexible printed circuit board (330) such that a first printed circuit board (310) within a first housing (210) and a second printed circuit board (320) within a second housing (220) are electrically connected.

For example, the support plate (340) may fasten at least a portion of the flexible printed circuit board (330) to the support plate (340) so that the flexible printed circuit board (330) does not detach from the support plate (340). For example, the support plate (340) may extend from a first printed circuit board (310) disposed within a first housing (210) upwardly across the hinge structure (250) (e.g., across the +x direction) to a second printed circuit board (320) disposed within a second housing (220).

[0071] For example, the support plate (340) may be a component of the housing (200). For example, the support plate (340) may be a component of the housing (200) for supporting the hinge structure (250) and / or the display (e.g., the display (230) of FIG. 2A). For example, a portion of the support plate (340) may form at least a portion of the first housing (210), and the remaining portion of the support plate (340) may form at least a portion of the second housing (220). For example, the support plate (340) may be referred to as, but is not limited to, the first bracket (215) and the second bracket (227) of FIG. 2C.

For example, the second support plate (340b) can fasten a portion (e.g., the fifth portion (335)) of a flexible printed circuit board (330) within the second housing (220) to the second housing (220).

[0073] For example, the hole (345) may be formed along an edge of the first printed circuit board (310). For example, the hole (345) may be formed in a portion of the support plate (340) adjacent to the first printed circuit board (310). For example, the flexible printed circuit board (330) may pass through the hole (345).

For example, the waterproofing member (350) may be positioned within the hole (345) and may come into contact with at least a portion of the flexible printed circuit board (330) passing through the hole (345). For example, the waterproofing member (350) may accommodate at least a portion of the flexible printed circuit board (330) by filling the interior of the hole (345). The waterproof member (350) can fasten at least a portion of the flexible printed circuit board (330) into the hole (345). For example, at least a portion of the waterproof member (350) can be configured to fill the interior of the hole (345) by injecting a waterproof material into the interior of the hole (345), but is not limited thereto. The electronic device (101), by including the waterproof member (350), can prevent and / or inhibit / block foreign substances from entering the space between the support plate (340) and the hinge structure (250) from the outside of the electronic device (101) through the hole (345).

The plurality of conductive pins (360) connecting at least some of the plurality of layers to each other may penetrate the flexible printed circuit board (330) and be connected to a conductive pattern in the first printed circuit board (310) and / or a conductive pattern in the second printed circuit board (320), thereby connecting the flexible printed circuit board (330) (or a plurality of layers of the flexible printed circuit board) and the first printed circuit board (310) and / or the second printed circuit board (320) to each other. For example, a plurality of conductive pins (360) may penetrate a flexible printed circuit board (330). The plurality of conductive pins (360) may, for example, penetrate a plurality of layers included in the flexible printed circuit board (330).

The first region (331) may include a first connector (331a) including a first set of conductive pins (361), and a second connector (331b) including a second set of conductive pins (362) and spaced apart from the first connector (331a). For example, the first region (331) may be a region disposed on the first printed circuit board (310). For example, the first region (331) may be a region fastened to the first printed circuit board (310). For example, the first region (331) may be a region coupled to the first printed circuit board (310). For example, the first region (331) may be a region that overlaps the first printed circuit board (310) when viewed from above (e.g., when viewed in the -z direction). For example, the first region (331) may be a region where at least some of the plurality of conductive pins (360) electrically connected to the first printed circuit board (310) within the first housing (210) (e.g., the first set of conductive pins (361), the second set of conductive pins (362)) are disposed. For example, the first region (331) may be disposed on a side (e.g., the first side (310a) of FIG. 4A) opposite to a side (e.g., the second side (310b) of FIG. 4A) of the printed circuit board (310) that faces a display (e.g., the display (230) of FIG. 2A, the flexible display (430) of FIG. 4A).

[0077] For example, the first connector (331a) may be a portion electrically connected to the first printed circuit board (310) via the first set of conductive pins (361). For example, the first connector (331a) may extend along the hole (345) in a direction in which the hole (345) extends (e.g., +y direction). For example, the first connector (331a) may have a major axis in a direction parallel to the folding axis (f). For example, the first connector (331a) may have a minor axis in a direction perpendicular to the folding axis (f). For example, the first connector (331a) may be closer to the hole (345) than the second connector (331b) which is spaced apart from the first connector (331a). However, the present invention is not limited thereto. For example, the second connector (331b) may be separated from the first connector (331a). For example, the second connector (331b) may be electrically connected to the first printed circuit board (310) via the second set of conductive pins (362). For example, the second connector (331b) may be arranged along the first battery (264a) arranged within the first housing (210). For example, the second connector (331b) may have a major axis in a direction perpendicular to the folding axis (f). For example, the second connector (331b) may have a minor axis in a direction parallel to the folding axis (f). However, the present invention is not limited thereto. The flexible printed circuit board (330) may be configured to provide space for electronic components mounted on the first printed circuit board (310) by including a first region (331) including a first connector (331a) and a second connector (331b) spaced apart from the first connector (331a), and to have a plurality of conductive pins (360) arranged within the flexible printed circuit board (330) for connection with the first printed circuit board (310).

[0078] According to one embodiment, the flexible printed circuit board (330) may include a first set of conductive lines (e.g., the first set of conductive lines (521) of FIG. 5 ) connected to a first set of conductive pins (361), and a second set of conductive lines (e.g., the second set of conductive lines (522) of FIG. 5 ) connected to a second set of conductive pins (362). For example, the first set of conductive lines (521) may be connected to a first connection portion of the first printed circuit board (310) via the first set of conductive pins (361). The first connection portion may be a portion connected to the first connector (331a). For example, the second set of conductive lines (522) may be connected to a second connection portion of the first printed circuit board (310) via the second set of conductive pins (362). The second connection portion may be a portion connected to the second connector (331b). For example, the first set of conductive lines (521) and the second set of conductive lines (522) may be connected to the first printed circuit board (310), respectively, thereby providing various functions. The first set of conductive lines (521) and the second set of conductive lines (522) will be described later with reference to FIG. 5.

[0079] According to one embodiment, the flexible printed circuit board (330) may include a second region (332) between the support plate (340) and the hinge structure (250). For example, the second region (332) may be disposed on at least a portion of the hinge structure (250) (e.g., the mounting portion (383)). For example, the second region (332) may be covered by the support plate (340). For example, the second region (332) may be an region that overlaps the hinge structure (250) when the flexible printed circuit board (330) is viewed from above (e.g., when viewed in the -z direction). For example, the second region (332) may be an region that is disposed under the support plate (340) with respect to the +z-axis direction. The flexible printed circuit board (330) may be configured to electrically connect the first printed circuit board (310) and the second printed circuit board (320) across the hinge structure (250) by including the second region (332).

[0080] According to one embodiment, the flexible printed circuit board (330) may include a third region (333) that includes a slit (330a) for connecting the first region (331) and the second region (332) through a hole (345) and for separating the first connector (331a) and the second connector (331b) of the first region (331). For example, the third region (333) may extend from the first region (331) to the second region (332). For example, at least a portion of the third region (333) may be connected to the second region (332) and thus face the support plate (340). The remaining portion of the third region (333) may be disposed on the first printed circuit board (310) by being connected to the first region (331) through the hole (345) of the support plate (340). For example, at least a portion of the third region (333) may be fastened to the support plate (340).

[0081] For example, the slit (330a) may be formed within the third region (333). For example, at least a portion of the slit (330a) may be disposed on the first printed circuit board (310). For example, the slit (330a) may be formed by separating the first connector (331a) and the second connector (331b) of the first region (331). For example, the slit (330a) may extend from the first region (331) toward the hole (345). For example, the slit (330a) may be disposed between portions (e.g., the first branch portion (333a) and the second branch portion (333b)) connected to the first connector (331a) and the second connector (331b) spaced apart from the first connector (331a) within the third region (333). The above slit (330a) may be referred to as a gap formed between the portions respectively connected to the first connector (331a) and the second connector (331b) within the third region (333), but is not limited thereto. The third region (333) may be configured to include the slit (330a) to separate the first connector (331a) and the second connector (331b) and to allow the first connector (331a) and the second connector (331b) to be easily connected to the first printed circuit board (310).

[0082] According to one embodiment, a slit (330a) may be formed between a first set of conductive lines (521) connected to a first set of conductive pins (361) and a second set of conductive lines (522) connected to a second set of conductive pins (362) so as to space the first connector (331a) and the second connector (331b) apart from each other. A portion of the slit (330a) may be disposed within the waterproof member (350).

[0083] According to one embodiment, the first region (331) may be arranged along the periphery (315) of the first printed circuit board (310). For example, the first connector (331a) of the first region (331) may be arranged along the first peripheral part (315a) of the periphery (315) of the first printed circuit board (310) adjacent to the hole (345) of the support plate (340). The second connector (331b) spaced apart from the first connector (331a) may be arranged along the second peripheral part (315b) of the periphery (315) of the first printed circuit board (310) that is connected to the first peripheral part (315a). The first region (331) may be configured to provide additional space on the first printed circuit board (310) for electronic components mounted on the first printed circuit board (310) by being positioned along an edge (315) of the first printed circuit board (310).

[0084] According to one embodiment, the size (S1) of the first printed circuit board (310) may be larger than the size (S2) of the second printed circuit board (320). For example, when the electronic device (101) is viewed from above (e.g., when viewed in the -z direction), the area of ​​the first printed circuit board (310) may be larger than the area of ​​the second printed circuit board (320). For example, the volume of the space occupied by the first printed circuit board (310) within the first housing (210) may be larger than the volume of the space occupied by the second printed circuit board (320) within the second housing (220).

[0085] According to one embodiment, since the size (S1) of the first printed circuit board (310) is larger than the size (S2) of the second printed circuit board (320), the first area (331) of the flexible printed circuit board (330) connected to the first printed circuit board (310) can be positioned along the edge (315) of the first printed circuit board (310) adjacent to the hole (345) of the support plate (340). Since the length of the third region (333) extending through the hole (345) and along the edge (315) to the first region (331) is relatively short (e.g., the length (d1) of the first branch portion (333a) and / or the length (d2) of the second branch portion (333b)), the probability of damage to the third region (333) may increase due to the slit (330a) in the third region (333). The flexible printed circuit board (330) may require a structure to reduce damage to the third region (333) of the flexible printed circuit board (330).

[0086] According to one embodiment, the slit (330a) may be at least partially disposed in the waterproof member (350) by extending from the first region (331) into the hole (345).

[0087] For example, the slit (330a) may be formed within the third region (333) at least partially disposed within the hole (345). For example, the slit (330a) may be at least partially disposed within the hole (345). For example, the slit (330a) may be at least partially disposed within the hole (345), such that the slit (330a) may be at least partially filled by the waterproofing member (350) disposed within the hole (345). For example, at least a portion of the waterproofing member (350) may pass through at least a portion of the slit (330a). For example, the slit (330a) may extend from the first region (331) toward the waterproofing member (350). For example, at least a portion of the slit (330a) may allow a waterproofing material of the waterproofing member (350) to pass through. For example, the slit (330a) may be at least partially surrounded by the hole (345). For example, at least a portion of the slit (330a) may face the inner surface of the hole (345). The slit (330a) may extend from the first region (331) into the hole (345), thereby reducing damage to the third region (333) caused by the slit (330a).

[0088] According to one embodiment, the third region (333) may include a first branch portion (333a) connected to the first connector (331a), and a second branch portion (333b) connected to the second connector (331b) and separated from the first branch portion (333a) by a slit (330a). A branch point (p1) within the slit (330a) at which the first branch portion (333a) and the second branch portion (333b) are separated may be located within a hole (345) of the support plate (340).

[0089] For example, the first branch portion (333a) may be a portion extending from the first connector (331a) of the third region (333) into the interior of the hole (345). The second branch portion (333b) may be a portion extending from the second connector (331b) of the third region (333) into the interior of the hole (345). The slit (330a) may be formed by separating the first branch portion (333a) and the second branch portion (331b).

[0090] The branch point (p1) of the slit (330a) may be the point where the separation of the first branch portion (333a) and the second branch portion (333b) begins. For example, the first branch portion (333a) may be separated from the second branch portion (333b) based on the branch point (p1). For example, the branch point (p1) may be referred to as an end of the slit (330a), but is not limited thereto.

[0091] For example, the branch point (p1) may be located within the hole (345). For example, the branch point (p1) may be covered by the waterproof member (350) by being disposed within the hole (345). For example, the branch point (p1) may be surrounded by the hole (345). For example, the branch point (p1) may face the inner surface of the hole (345). For example, at least a portion of the first branch portion (333a) and at least a portion of the second branch portion (333b) may be disposed within the hole (345). For example, the first branch portion (333a) and the second branch portion (333b) may be separated within the hole (345). For example, the first branch portion (333a) and the second branch portion (333b) may at least partially contact the waterproof member (350). For example, the first branch portion (333a) and the second branch portion (333b) can be fastened to the support plate (340) by a waterproof member (350). Since the branch point (p1) of the slit (330a) at which the first branch portion (333a) and the second branch portion (333b) are separated is positioned within the hole (345), the flexible printed circuit board (330) can reduce damage to the third region (333) for connecting the first region (331) to the first printed circuit board (310).

[0092] According to one embodiment, the length (d1) of the first branch portion (333a) may be smaller than the length (d2) of the second branch portion (333b). The length (d1) of the first branch portion (333a) may be located within a range of 2 mm or more and 4 mm or less. For example, since the first connector (331a) is arranged along the first peripheral portion (315a) adjacent to the hole (345), and the second connector (331b) spaced apart from the first connector (331a) is arranged along the second peripheral portion (315b) connected to the first peripheral portion (315a), the length (d1) of the first branch portion (333a) extending from the inside of the hole (345) to the first connector (331a) with respect to the branch point (p1) may be smaller than the length (d2) of the second branch portion (333b) extending from the inside of the hole (345) to the second connector (331b). The length (d1) of the first branch portion (333a) may correspond to the length (l1) of the slit (330a). By positioning the length (d1) of the first branch portion (333a) smaller than the length (d2) of the second branch portion (333b) within a range of 2 mm to 4 mm, the flexible printed circuit board (330) can reduce damage to the third area (333) for connecting the first area (331) to the first printed circuit board (310).

[0093] According to one embodiment, the hinge structure (250) may include a first hinge (381), a second hinge (382) spaced from the first hinge (381), and a mounting portion (383) between the first hinge (381) and the second hinge (382) for accommodating a third region (333) of a flexible printed circuit board (330). For example, the first hinge (381) may include a first plate (381a) coupled with the first housing (210) and a second plate (381b) coupled with the second housing (220). The first plate (381a) may be rotatable relative to the second plate (381b) about the folding axis (f) so as to rotate the first housing (210) about the folding axis (f). For example, the second hinge (382) may be configured to be spaced apart from the first hinge (381) such that the hinge structure (250) forms a space between the first hinge (381) and the second hinge (382). The second hinge (382) may include a third plate (382a) coupled with the first housing (210) and a fourth plate (382b) coupled with the second housing (220). The third plate (382a) may be rotatable relative to the fourth plate (382b) about the folding axis (f) so as to rotate the first housing (210) about the folding axis (f).

[0094] For example, the mounting portion (383) may connect the first hinge (381) and the second hinge (382). The mounting portion (383) may provide a mounting space for the second region (332) of the flexible printed circuit board (330) so that the flexible printed circuit board (330) connects the first printed circuit board (310) and the second printed circuit board (320) through the space between the first hinge (381) and the second hinge (382). For example, the mounting portion (383) may include a first mounting structure (383a) between the first plate (381a) and the third plate (382a), and a second mounting structure (383b) between the second plate (381b) and the fourth plate (382b). However, without being limited thereto, the hinge structure (250) may include a structure for passing a flexible printed circuit board (330) connecting a first printed circuit board (310) within a first housing (210) and a second printed circuit board (320) within a second housing (220), thereby allowing the first printed circuit board (310) and the second printed circuit board (320) to be electrically connected.

[0095] In one embodiment, the flexible printed circuit board (330) may include a fourth region (334) that is connected to the second printed circuit board (320) and includes a third connector (334a) that includes a third set of conductive pins (363), and a fourth connector (334b) that is spaced from the third connector (334a) and includes a fourth set of conductive pins (364). The flexible printed circuit board (330) may include a fifth region (335) that connects the fourth region (334) and the second region (332) and includes another slit (330b) for separating the third connector (334a) and the fourth connector (334b).

[0096] For example, the fourth region (334) may be a region disposed on the second printed circuit board (320). For example, the fourth region (334) may be a region fastened to the second printed circuit board (320). For example, the fourth region (334) may be a region coupled to the second printed circuit board (320). For example, the fourth region (334) may be a region where at least some of the plurality of conductive pins (360) electrically connected to the second printed circuit board (320) within the second housing (220) (e.g., the third set of conductive pins (363), the fourth set of conductive pins (364)) are disposed. For example, the third connector (334a) may be a portion electrically connected to the second printed circuit board (320) via the third set of conductive pins (363). For example, the third connector (334a) may extend in a direction perpendicular to the folding axis (f), but is not limited thereto. For example, the fourth connector (334b) may be separated from the third connector (334a). For example, the fourth connector (334b) may be electrically connected to the second printed circuit board (320) via the fourth set of conductive pins (364). For example, the fourth connector (334b) may extend in a direction parallel to the folding axis (f), but is not limited thereto. The flexible printed circuit board (330) may be configured to provide space for electronic components mounted on the second printed circuit board (320) by including a fourth region (334) including a third connector (334a) and a fourth connector (334b) spaced apart from the third connector (334a), and to have a plurality of conductive pins (360) arranged within the flexible printed circuit board (330) for connection with the second printed circuit board (320).

[0097] For example, the fifth region (335) may extend from the second region (332) to the fourth region (334). For example, the support plate (340) may include another hole (346) for passing the fifth region (335). The other hole (346) may be formed in the second support plate (340b) coupled with the second housing (220). The fifth region (335) may connect the second region (332) and the fourth region (334) through the other hole (346). For example, since the size (S1) of the first printed circuit board (310) is larger than the size (S2) of the second printed circuit board (320), another slit (330b) in the fifth region (335) for separating the third connector (334a) and the fourth connector (334b) may be disposed outside another hole (346) passing through the fifth region (335). The other slit (330b) may, for example, be disposed at least partially on the second battery (246b) in the second housing (220). For example, the third branch portion (335a) of the fifth region (335) may be disposed outside another hole (346) extending from the third connector (334a) and passing through the fifth region (335). The fourth branch portion (335b), which is separated from the third branch portion (335a) by another slit (330b) of the fifth region (335), may be positioned outside the other hole (346). The other branch point (p2) of the other slit (330b) through which the third branch portion (335a) and the fourth branch portion (335b) are separated may be located, for example, on the second battery (264b) within the second housing (220).The flexible printed circuit board (330) has another slit (330b) positioned outside of another hole (346) for separating the third connector (334a) and the fourth connector (334b) connected to the second printed circuit board (320), thereby reducing damage to the fifth area (335) connecting the second area (332) and the fourth area (334) by the other slit (330b).

[0098] According to one embodiment, the length (l1) of the slit (330a) in the third region (333) may be smaller than the length (l2) of another slit (330b) in the fifth region (335). The second battery (372) may be spaced apart from the second printed circuit board (320). The fifth region (335) may extend from the second region (332) across the second battery (264b) to the fourth region (334). For example, the length (l1) of the slit (330a) may correspond to a smaller length between the length (d1) of the first branch portion (333a) and the length (d2) of the second branch portion (333b). The length (l2) of the other slit (330b) may correspond to a smaller length between the length (d3) of the third branch portion (335a) and the length (d4) of the fourth branch portion (335b). The length (l1) of the slit (330a) extending from the first region (331) to the inside of the hole (345) may be smaller than the length (l2) of the other slit (330b) extending from the fourth region (334) and disposed outside of the other hole (346). For example, since the length (l2) of the other slit (330b) is greater than the length (l1) of the slit (330a), at least a portion of the fifth region (335) including the other slit (330b) may be at least partially disposed on the second battery (264b) within the second housing (220) adjacent to the second printed circuit board (320). The fifth region (335) extends from the second region (332) across the second battery (264b) to the fourth region (334), thereby reducing damage to the fifth region (335) by another slit (330b).

[0099] According to the above-described embodiment, the flexible printed circuit board (330) of the electronic device (101) can electrically connect the first printed circuit board (310) and the second printed circuit board (320) by extending from the first printed circuit board (310) across the hinge structure (250) to the second printed circuit board (320). The flexible printed circuit board (330) can be configured to include a slit (330a) extending from a first region (331) connected to the first printed circuit board (310) into a hole (345) of a support plate (340), thereby reducing damage to a third region (333) including the slit (330a) by the slit (330a) and allowing the first region (331) to be easily fastened to the first printed circuit board (310).

[0100] FIG. 4A is a partial cross-sectional view of an exemplary electronic device taken along line A-A' of FIG. 3C, according to various embodiments. FIG. 4B illustrates a portion of an exemplary electronic device, according to various embodiments.

[0101] Referring to FIGS. 4A and 4B, an electronic device (101) may include a first housing (210), a second housing (220), and a hinge structure (250) that rotatably connects the first housing (210) and the second housing (220).

The electronic device (101) may include a support plate (340) on the hinge structure (250) including a hole (345) for passing the flexible printed circuit board (330), and a waterproof member (350) disposed within the hole (345). The flexible printed circuit board (330) may include a first region (331) connected to the first printed circuit board (310) and including a first connector (331a) including a first set of conductive pins, and a second connector (331b) including a second set of conductive pins and spaced apart from the first connector (331a). The flexible printed circuit board (330) may include a second region (332) between the support plate (340) and the hinge structure (250). The above flexible printed circuit board (330) may include a third region (333) that includes a slit (330a) for connecting the first region (331) and the second region (332) through the hole (345) and for separating the first connector (331a) and the second connector (331b).The slit (330a) may be at least partially disposed within the waterproof member (350) by extending from the first region (331) into the hole (345). According to one embodiment, the hinge structure (250) may include a first hinge plate (252) coupled with the first housing (210), and a second hinge plate (253) coupled with the second housing (220).

[0102] Hereinafter, a description of the configuration having the same reference numerals as described above in FIGS. 3a to 3c is omitted.

[0103] According to one embodiment, the electronic device (101) may include at least one support member (410) for fastening the flexible printed circuit board (330) to the support plate (340). The third region (333) of the flexible printed circuit board (330) may include at least one bending portion (333c) bent by the at least one support member (410) to connect the first region (331) and the second region (332).

[0104] For example, at least one support member (410) can be in contact with the flexible printed circuit board (330). For example, at least one support member (410) can press the flexible printed circuit board (330) toward the support plate (340). For example, at least one support member (410) can be covered by the support plate (340). For example, at least one support member (410) can include a first support member (411) for supporting a third region (333) of the flexible printed circuit board (330), and a second support member (412). The first support member (411) can extend from the inner surface of the hole (345) toward the second region (332) of the flexible printed circuit board (330). The first support member (411) can fasten the third region (333) passing through the hole (345) to the first support plate (340a) in which the hole (345) is formed by pressing at least a portion of the third region (333). For example, the third region (333) pressed by the first support member (411) can be a region of the flexible printed circuit board (330) that is flexible and thus deformable. For example, the second support member (412) can be supported by the first support member (411) by being disposed on the first support member (411). The second support member (412) can press the third region (333) of the flexible printed circuit board (330) toward the first support plate (340a) together with the first support member (411), thereby fixing the third region (333) to the first support plate (340a). For example, the third region (333) pressed by the second support member (412) can be a portion of the flexible printed circuit board (330) that has relatively high rigidity.The electronic device (101) can reduce the separation of the third region (333) of the flexible printed circuit board (330) from the support plate (340) by including the first support member (411) and the second support member (412).

[0105] Although at least one support member (410) is described as including a first support member (411) and a second support member (412), it is not limited thereto. At least one support member (410) may include a plurality of support members for fixing a fifth region (335) of a flexible printed circuit board (330) to a second support plate (340b) coupled with a second housing (220).

[0106] For example, at least one bending portion (333c) may be arranged between at least one support member (410) and the support plate (340). The flexible printed circuit board (330) may be configured such that the flexible printed circuit board (330) is fastened to the support plate (340) and connected to the first printed circuit board (310) through the hole (345) of the support plate (340) by including the at least one bending portion (333c).

[0107] According to one embodiment, the electronic device (101) may include at least one adhesive member (420) for attaching the flexible printed circuit board (330) to the support plate (340). For example, the at least one adhesive member (420) may include a first adhesive member (421) between the flexible printed circuit board (330) and the support plate (340). For example, the at least one adhesive member (420) may include a second adhesive member (422) between the flexible printed circuit board (330) and the at least one support member (410). For example, the flexible printed circuit board (330) may be attached to the second support member (412) by the second adhesive member (422) attached to the second support member (412). The flexible printed circuit board (330) attached on the second support member (412) can be attached to the support plate (340) via the first adhesive member (421) by the support plate (340) having the first adhesive member (421) attached thereto being coupled to the first housing (210) and the second housing (220). The flexible printed circuit board (330) can be attached to the support plate (340) by the first adhesive member (421) and can be fastened to the support plate (340) by being pressed by the support plate (340) and the second support member (412). However, the present invention is not limited thereto.

[0108] According to one embodiment, the electronic device (101) may include a flexible display (430) (e.g., the display module (160) of FIG. 1, the display (230) of FIG. 2A). The flexible display (430) may include a first display area (431) coupled with a first housing (210) (e.g., the first display area (231) of FIG. 2A), a second display area (432) coupled with a second housing (220) (e.g., the second display area (232) of FIG. 2A), and a deformable third display area (433) connecting the first display area (431) and the second display area (432) (e.g., the third display area (233) of FIG. 2A). For example, the first display area (431) may be disposed on the first housing (210). The second display area (432) may be spaced apart from the first display area (431) and disposed on the second housing (220). For example, the first display area (431) and the second display area (432) may be referred to as a flat portion of the flexible display (430) in that they substantially form a plane, but are not limited thereto. For example, the third display area (433) may extend from the first display area (431) to the second display area (432). The third display area (433) may be disposed on the hinge structure (250). For example, the third display area (433) may be configured to be deformed by the first housing (210) rotating relative to the second housing (220) by the hinge structure (250). For example, the third display area (433) may be an area placed on the second area (332) of the flexible printed circuit board (330). The electronic device (101) may provide various user experiences to the user by including a flexible display (430) including a deformable third display area (433).

[0109] According to one embodiment, the electronic device (101) may include an antenna structure (440) disposed on a first region (331) and for communicating with an external electronic device (e.g., the electronic device (102) or the electronic device (104) of FIG. 1), and an interposer (450) disposed between a first printed circuit board (310) and the antenna structure (440) so as to face the flexible printed circuit board (330). For example, the first printed circuit board (310) may include a first side (310a) to which the first region (331) is fastened, and a second side (310b) opposite to the first side (310a) and facing the flexible display (430). The antenna structure (440) may be disposed on the first side (310a) of the first printed circuit board (310) to which the first region (331) of the flexible printed circuit board (330) is fastened. The antenna structure (440) may at least partially face the first area (331). For example, the antenna structure (440) may overlap the first area (331) when the first surface (310a) of the first printed circuit board (310) is viewed from above. The antenna structure (440) may be referred to as an NFC (near field communication) antenna for short-range wireless communication, but is not limited thereto. For example, the interposer (450) may be disposed between the first surface (310a) of the first printed circuit board (310) and the antenna structure (440). For example, the interposer (450) may be interposed between the first printed circuit board (310) and the antenna structure (440), thereby supporting the antenna structure (440).

[0110] For example, the length of the third region (333) extending from the first region (331) through the hole (345) can be limited by the antenna structure (440) on the first region (331). The slit (330a) in the third region (333) can reduce damage to the third region (333) due to the short length of the third region (333) by extending from the first region (331) into the inside of the hole (345). For example, the branch point (p1) of the slit (330a) where the first branch portion (333a) and the second branch portion (333b) of the third region (333) are separated can be located in the hole (345) where the waterproof member (350) is arranged.

[0111] For example, by the antenna structure (440) and the interposer (450), the first region (331) including the first connector (331a) and the second connector (331b) can be arranged adjacent to the hole (345). For example, since the space between the first printed circuit board (310) and the antenna structure (440) is relatively small, the first connector (331a) and the second connector (331b) can be arranged at the edge of the first printed circuit board (310). The slit (330a) can be arranged at least partially within the waterproof member (350) inside the hole (345), thereby reducing damage to the flexible printed circuit board (330) caused by the slit (330a).

[0112] According to one embodiment, the waterproofing member (350) may include at least one of a cure-in-place gasket (CIPG) and rubber. The first region (331) of the flexible printed circuit board (330) may include carbon nanotubes (CNT).

[0113] For example, the waterproofing member (350) may include a first waterproofing member (351) and a second waterproofing member (352). The first waterproofing member (351) may be filled in the hole (345) after the flexible printed circuit board (330) passes through the hole (345). The second waterproofing member (352) may press at least a portion of the flexible printed circuit board (330) passing through the hole (345) toward the inner surface of the hole (345). The second waterproofing member (352) may occupy the inner surface of the hole (345) together with the first waterproofing member (351). For example, at least a portion of the slit (330a) may be filled by the first waterproofing member (351). For example, the branch point (p1) of the slit (330a) where the first branch portion (333a) and the second branch portion (333b) are separated may be located within the first waterproof member (351). According to one embodiment, the first waterproof member (351) may include CIPG, and the second waterproof member (352) may include rubber, but is not limited thereto.

[0114] According to one embodiment, the support plate (340) may include a side wall (341) that forms at least a portion of the hole (345) and protrudes toward the third region (333). A length (d5) of the side wall (341) that protrudes toward the third region (333) from the first surface (310a) on which the first region (331) of the first printed circuit board (310) is disposed may be positioned within a range of 1 mm or more and 2 mm or less. A distance (d6) between the side wall (341) and the first region (331) may be positioned within a range of 2 mm or more and 4 mm or less. The length of the third region (333) extending from the inside of the hole (345) to the first region (331) can be limited by the length (d5) being located within a range of 1 mm to 2 mm, and the distance (d6) being located within a range of 2 mm to 4 mm. The slit (330a) in the third region (333) can reduce damage to the third region (333) due to the short length of the third region (333) by extending from the first region (331) to the inside of the hole (345). For example, the length (l1) of the slit (330a) can be greater than the distance (d6) between the side wall (341) and the first region (331). However, the present invention is not limited thereto.

[0115] According to the above-described embodiment, the flexible printed circuit board (330) can be configured to include a slit (330a) extending from a first region (331) connected to the first printed circuit board (310) into a hole (345) of a support plate (340), thereby reducing damage to a third region (333) including the slit (330a) by the slit (330a) and allowing the first region (331) to be easily fastened to the first printed circuit board (310).

The flexible printed circuit board (330) may include a second region (e.g., support plate (340) of FIG. 3a) between the support plate (340) and the hinge structure (250). It may include a second area (332).The flexible printed circuit board (330) may include a third region (333) including a slit (330a) for connecting the first region (331) and the second region (332) through the hole (345) and for separating the first connector (331a) and the second connector (331b). The slit (330a) may be at least partially disposed within the waterproof member (350) by extending from the first region (331) into the hole (345).

[0118] According to one embodiment, the flexible printed circuit board (330) may include a power supply area (510) for supplying power to electronic components on the first printed circuit board (310) via a plurality of conductive pins (360), a plurality of signal lines (520), and a ground area (530).

[0119] For example, the power supply area (510) may include a first power supply area (511) for supplying power to electronic components of the first printed circuit board (310) via at least some of the first set of conductive pins (361) within the first connector (331a), and a second power supply area (512) for supplying power to electronic components of the first printed circuit board (310) via at least some of the second set of conductive pins (362) within the second connector (331b). The first power supply area (511) may extend, for example, from the first branch portion (333a) to the first connector (331a). The second power supply area (512) may extend from the second branch portion (333b) to the second connector (331b). The first power supply region (511) and the second power supply region (512) may be arranged along a slit (330a) that separates the first branch portion (333a) and the second branch portion (333b). For example, the plurality of signal lines (520) may include a first set of conductive lines (521) for transmitting data to a first set of conductive pins (361), and a second set of conductive lines (522) for transmitting data to a second set of conductive pins (362).

[0120] For example, the power supply area (510) may include a plurality of power signal lines for supplying power to electronic components mounted on the first printed circuit board (310). For example, the first set of conductive lines (521) may be configured to transmit a signal to a display (e.g., the display (230) of FIG. 2A) connected to the first printed circuit board (310) via the first set of conductive pins (361). For example, the second set of conductive lines (522) may be configured to transmit signals to a display (230), a sensor module (e.g., the sensor module (176) of FIG. 1), a camera module (e.g., the camera module (180) of FIG. 1), an audio module (e.g., the audio module (170) of FIG. 1), and a universal subscriber identity module (USIM) connected to the first printed circuit board (310) via the second set of conductive pins (362), but is not limited thereto.

A thickness (t1) of the third ground region (533) may be positioned within a range of 0.1 mm or more and 0.2 mm or less. For example, by removing at least a portion of the third ground region (533), the length of the slit (330a) (e.g., the length (l1) of FIG. 3a) may be increased. By positioning the thickness (t1) of the third ground region (533) within a range of 0.1 mm or more and 0.2 mm or less, the slit (330a) can be configured to extend from the first region (331) into the inside of the hole (345) of the support plate (340).

By positioning the thickness (t2) between the third ground region (533) and the slit (330a) of the flexible printed circuit board (330) within a range of 1.5 mm or more and 2.5 mm or less, the flexible printed circuit board (330) can reduce the exposure of the third ground region (533) and / or the power supply region (510) to the outside due to damage to the flexible printed circuit board (330).

[0123] According to the above-described embodiment, the flexible printed circuit board (330) can extend the length (l1) of the slit (330a) by adjusting the thickness (t1) of the third ground region (533) arranged along the slit (330a).
