[0019] FIG. 1 is a drawing illustrating an unfolded state of an electronic device (100) according to various embodiments of the present invention. FIG. 2 is a drawing illustrating a folded state of the electronic device (100) of FIG. 1 according to various embodiments of the present invention.

[0020] Referring to FIG. 1, the electronic device (100) may include a pair of housing structures (110, 120) (e.g., foldable housing structures) rotatably joined by a hinge structure (e.g., hinge structure (164) of FIG. 3) so as to be folded against each other, a hinge cover (e.g., hinge cover (165) of FIG. 2) covering a foldable portion of the pair of housing structures (110, 120), and a display (130) (e.g., flexible display, foldable display, or first display) disposed in the space formed by the pair of housing structures (110, 120). In this document, the surface on which the display (130) is disposed may be defined as the front surface of the electronic device (100), and the surface opposite to the front surface may be defined as the rear surface of the electronic device (100). In addition, the surface surrounding the space between the front and the rear can be defined as the side of the electronic device (100).

[0021] In one embodiment, a pair of housing structures (110, 120) may include a first housing structure (110) including a sensor area (131d), a second housing structure (120), a first rear cover (140), and a second rear cover (150). The pair of housing structures (110, 120) of the electronic device (100) are not limited to the shapes and combinations shown in FIGS. 1 and 2, and may be implemented by other shapes or combinations and / or combinations of parts. For example, in another embodiment, the first housing structure (110) and the first rear cover (140) may be formed integrally, and the second housing structure (120) and the second rear cover (150) may be formed integrally.

[0022] According to one embodiment, the first housing structure (110) and the second housing structure (120) are positioned on both sides of the folding axis (A-axis) and may have a shape that is symmetrical overall with respect to the folding axis (A-axis). According to one embodiment, the angle or distance between the first housing structure (110) and the second housing structure (120) may vary depending on whether the state of the electronic device (100) is in a flat stage or unfolding state, a folding state, or an intermediate state. According to one embodiment, the first housing structure (110) additionally includes a sensor area (131d) in which various sensors are positioned, unlike the second housing structure (120), but may have a mutually symmetrical shape in other areas. In another embodiment, the sensor area (131d) may be additionally positioned or replaced in at least a part of the second housing structure (120).

[0023] In one embodiment, the first housing structure (110) is connected to a hinge structure (e.g., hinge structure (164) of FIG. 3) in an unfolded state of the electronic device (100) and may include a first surface (111) positioned to face the front of the electronic device (100), a second surface (112) facing in the opposite direction of the first surface (111), and a first side member (113) that surrounds at least a portion of the space between the first surface (111) and the second surface (112). In one embodiment, the first side member (113) may include a first side (113a) arranged parallel to the folding axis (A axis), a second side (113b) extending in a direction perpendicular to the folding axis from one end of the first side (113a), and a third side (113c) extending in a direction perpendicular to the folding axis (A axis) from the other end of the first side (113a).

[0024] In one embodiment, the second housing structure (120) is connected to a hinge structure (e.g., hinge structure (164) of FIG. 3) in the unfolded state of the electronic device (100) and may include a third surface (121) positioned to face the front of the electronic device (100), a fourth surface (122) facing in the opposite direction of the third surface (121), and a second side member (123) that surrounds at least a portion of the space between the third surface (121) and the fourth surface (122). In one embodiment, the second side member (123) may include a fourth side (123a) positioned parallel to the folding axis (A axis), a fifth side (123b) extending in a direction perpendicular to the folding axis (A axis) from one end of the fourth side (123a), and a sixth side (123c) extending in a direction perpendicular to the folding axis (A axis) from the other end of the fourth side (123a). In one embodiment, the third side (121) may be positioned to face the first side (111) in a folded state.

[0025] In one embodiment, the electronic device (100) may include a recess (101) formed to accommodate a display (130) through the structural shape combination of a first housing structure (110) and a second housing structure (120). The recess (101) may have substantially the same size as the display (130). In one embodiment, due to the sensor area (131d), the recess (101) may have two or more different widths in a direction perpendicular to the folding axis (A axis). For example, the recess (101) may have a first width (W1) between a first part (120a) parallel to the folding axis (A-axis) of the second housing structure (120) and a first part (110a) formed at the edge of the sensor area (131d) of the first housing structure (110), and a second width (W2) formed by a second part (120b) of the second housing structure (110) and a second part (110b) parallel to the folding axis (A-axis) that does not correspond to the sensor area (131d) of the first housing structure (110). In this case, the second width (W2) may be formed to be longer than the first width (W1). For example, the recess (101) may be formed to have a first width (W1) formed from a first part (110a) of a first housing structure (110) having a mutually asymmetrical shape to a first part (120a) of a second housing structure (120), and a second width (W2) formed from a second part (110b) of a first housing structure (110) having a mutually symmetrical shape to a second part (120b) of a second housing structure (120). In one embodiment, the first part (110a) and the second part (110b) of the first housing structure (110) may be formed to have different distances from the folding axis (A axis). The width of the recess (101) is not limited to the illustrated example. In various embodiments, the recess (101) may have two or more different widths by the shape of the sensor area (131d) or the part having an asymmetric shape of the first housing structure (110) and the second housing structure (120).

[0026] In one embodiment, at least a portion of the first housing structure (110) and the second housing structure (120) may be formed of a metal or non-metal material having a selected size of rigidity to support the display (130).

[0027] In one embodiment, the sensor area (131d) may be formed to have a predetermined area adjacent to one side corner of the first housing structure (110). However, the arrangement, shape, or size of the sensor area (131d) is not limited to the illustrated example. For example, in another embodiment, the sensor area (131d) may be provided in any area between the top corner and the bottom corner of the other corner of the first housing structure (110). In another embodiment, the sensor area (131d) may be placed in at least a portion of the second housing structure (120). In another embodiment, the sensor area (131d) may be placed to extend to the first housing structure (110) and the second housing structure (120). In one embodiment, the electronic device (100) may be components for performing various functions that are positioned to be exposed on the front of the electronic device (100) through a sensor area (131d) or through one or more openings provided in the sensor area (131d). In various embodiments, the components may include, for example, at least one of a front camera device, a receiver, a proximity sensor, an ambient light sensor, an iris recognition sensor, an ultrasonic sensor, or an indicator.

[0028] In one embodiment, the first rear cover (140) may be placed on the second side (112) of the first housing structure (110) and may have a substantially rectangular periphery. In one embodiment, at least a portion of the periphery may be covered by the first housing structure (110). Similarly, the second rear cover (150) may be placed on the fourth side (122) of the second housing structure (120) and at least a portion of its periphery may be covered by the second housing structure (120).

[0029] In the illustrated embodiment, the first rear cover (140) and the second rear cover (150) may have substantially symmetrical shapes with respect to the folding axis (A-axis). In another embodiment, the first rear cover (140) and the second rear cover (150) may include various different shapes. In another embodiment, the first rear cover (140) may be formed integrally with the first housing structure (110), and the second rear cover (150) may be formed integrally with the second housing structure (120).

[0030] In one embodiment, the first rear cover (140), the second rear cover (150), the first housing structure (110), and the second housing structure (120) may be combined to provide a space in which various components of the electronic device (100) (e.g., printed circuit board, antenna module, sensor module, or battery) can be placed. In one embodiment, one or more components may be placed or visually exposed on the rear of the electronic device (100). For example, one or more components or sensors may be visually exposed through the first rear area (141) of the first rear cover (140). In various embodiments, the sensors may include a proximity sensor, a rear camera device, and / or a flash. In another embodiment, at least a portion of a sub-display (152) (e.g., a second display) may be visually exposed through the second rear area (151) of the second rear cover (150). In another embodiment, the electronic device (100) may include a speaker module (153) positioned through at least a portion of the second rear cover (150).

[0031] The display (130) may be placed in a space formed by a pair of housing structures (110, 120). For example, the display (130) may be seated in a recess (101) formed by a pair of housing structures (110, 120) and may be positioned to occupy substantially most of the front surface of the electronic device (100). Thus, the front surface of the electronic device (100) may include the display (130) and a portion of the first housing structure (110) adjacent to the display (130) (e.g., an edge area) and a portion of the second housing structure (120) (e.g., an edge area). In one embodiment, the rear surface of the electronic device (100) may include a first rear cover (140), a portion of a first housing structure (110) adjacent to the first rear cover (140) (e.g., an edge area), a second rear cover (150), and a portion of a second housing structure (120) adjacent to the second rear cover (150) (e.g., an edge area).

[0032] In one embodiment, the display (130) may mean a display in which at least some area can be deformed into a flat or curved surface. In one embodiment, the display (130) may include a folding area (131c), a first area (131a) disposed on one side (e.g., the right side of the folding area (131c)) relative to the folding area (131c), and a second area (131b) disposed on the other side (e.g., the left side of the folding area (131c). For example, the first area (131a) may be disposed on the first surface (111) of the first housing structure (110), and the second area (131b) may be disposed on the third surface (121) of the second housing structure (120). In one embodiment, the division of the display (130) into regions is exemplary, and the display (130) may be divided into multiple regions (e.g., four or more or two) according to structure or function. For example, in the embodiment illustrated in FIG. 1, the regions of the display (130) may be divided by a folding region (131c) extending parallel to the y-axis or a folding axis (A-axis), but in other embodiments, the display (130) may be divided into regions based on a different folding region (e.g., a folding region parallel to the x-axis) or a different folding axis (e.g., a folding axis parallel to the x-axis). The area division of the display described above is merely a physical division by a pair of housing structures (110, 120) and a hinge structure (e.g., the hinge structure (164) of FIG. 3), and substantially, the display (130) can display a single entire screen through the pair of housing structures (110, 120) and the hinge structure (e.g., the hinge structure (164) of FIG. 3). In one embodiment, the first area (131a) and the second area (131b) may have a shape that is symmetrical overall with respect to the folding area (131c).However, unlike the second region (131b), the first region (131a) may include a notch region (e.g., the notch region (133) of FIG. 3) cut according to the presence of the sensor region (131d), but other regions may have a shape symmetric to the second region (131b). For example, the first region (131a) and the second region (131b) may include a portion having a shape symmetric to each other and a portion having a shape asymmetric to each other.

[0034] Referring to FIG. 2, the hinge cover (165) may be configured to be positioned between the first housing structure (110) and the second housing structure (120) to cover an internal component (e.g., the hinge structure (164) of FIG. 3). In one embodiment, the hinge cover (165) may be covered by a part of the first housing structure (110) and the second housing structure (120) or exposed to the outside, depending on the operating state (flat state or folded state) of the electronic device (100).

[0035] For example, as shown in FIG. 1, when the electronic device (100) is in an unfolded state, the hinge cover (165) may be covered by the first housing structure (110) and the second housing structure (120) and not exposed. For example, as shown in FIG. 2, when the electronic device (100) is in a folded state (e.g., a completely folded state), the hinge cover (165) may be exposed to the outside between the first housing structure (110) and the second housing structure (120). For example, when the first housing structure (110) and the second housing structure (120) are in an intermediate state where they are folded with a certain angle, the hinge cover (165) may be at least partially exposed to the outside of the electronic device (100) between the first housing structure (110) and the second housing structure (120). In this case, the exposed area may be smaller than in a fully folded state. In one embodiment, the hinge cover (165) may include a curved surface.

[0036] Hereinafter, the operation of the first housing structure (110) and the second housing structure (120) and each area of ​​the display (130) according to the operating state of the electronic device (100) (e.g., flat state and folded state) will be described.

[0037] In one embodiment, when the electronic device (100) is in a flat state (e.g., the state of FIG. 1), the first housing structure (110) and the second housing structure (120) form an angle of 180 degrees, and the first area (131a) and the second area (131b) of the display may be arranged to face in the same direction. Additionally, the folding area (131c) may form a plane with the first area (131a) and the second area (131b). In another embodiment, when the electronic device (100) is in a flat state, the first housing structure (110) and the second housing structure (120) may be folded in opposite directions so that the second surface (112) and the fourth surface (122) face each other, and the first area (131a) and the second area (131b) of the display may be arranged to face in opposite directions relative to each other.

[0038] In one embodiment, when the electronic device (100) is in a folded state (e.g., the state of FIG. 2), the first housing structure (110) and the second housing structure (120) may be positioned facing each other. The first region (131a) and the second region (131b) of the display (130) may face each other and form a narrow angle (e.g., between 0 and 10 degrees). The folding region (131c) may be formed as a curved surface having at least a portion having a predetermined curvature.

[0039] In one embodiment, when the electronic device (100) is in an intermediate state, the first housing structure (110) and the second housing structure (120) may be arranged at a certain angle to each other. The first region (131a) and the second region (131b) of the display (130) may form an angle that is larger than the folded state and smaller than the unfolded state. The folding region (131c) may be formed of a curved surface having at least a certain curvature, and the curvature may be smaller than in the folded state.

[0041] FIG. 3 is an exploded perspective view of an electronic device (100) according to various embodiments of the present invention.

[0042] Referring to FIG. 3, in one embodiment, the electronic device (100) may include a display (130), a support member assembly (160), at least one printed circuit board (170), a first housing structure (110), a second housing structure (120), a first rear cover (140), and a second rear cover (150).

[0043] The display (130) may include a display panel (131) (e.g., a flexible display panel) and one or more plates (132) or layers on which the display panel (131) is placed. In one embodiment, one or more plates (132) may include a conductive plate (e.g., a Cu sheet or a SUS sheet) disposed between the display panel (131) and the support member assembly (160). According to one embodiment, the conductive plate may be formed to have an area substantially identical to the display, and the area facing the folding area of ​​the display may be formed to be bendable. The plate (132) may include at least one auxiliary material layer (e.g., a graphite material) disposed on the back surface of the display panel (131). In one embodiment, the plate (132) may be formed in a shape corresponding to the display panel (131). For example, a portion of the first plate (132) may be formed in a shape corresponding to the notch area (133) of the display panel (131).

[0044] The support member assembly (160) may include a first support member (161) (e.g., a first support plate), a second support member (162) (e.g., a second support plate), a hinge structure (164) disposed between the first support member (161) and the second support member (162), a hinge cover (165) covering the hinge structure (164) when viewed from the outside, and at least one wiring member (163) (e.g., a flexible printed circuit board (FPCB)) crossing the first support member (161) and the second support member (162).

[0045] In one embodiment, the support member assembly (160) may be disposed between the plate (132) and at least one printed circuit board (170). For example, the first support member (161) may be disposed between the first area (131a) of the display (130) and the first printed circuit board (171). The second support member (162) may be disposed between the second area (131b) of the display (130) and the second printed circuit board (172).

[0079] FIGS. 7a to 7e illustrate various variations of the region C2 of FIG. 5 according to various embodiments of the present invention. Although the drawings illustrate and describe a modified arrangement structure of the opening (4531) for reinforcing the rigidity of the upper portion of the conductive plate (450), the rigidity reinforcing structure of the lower portion of the conductive plate (450) may also have substantially the same configuration.

[0080] Referring to FIG. 7a, the conductive plate (450) may include a rigidity reinforcement portion (B1 portion) formed such that, for the rigidity reinforcement of the upper portion, at least partially in the upper region of the flexible portion (453), the opening (4531) in the second direction (e.g., x-axis direction) is completely omitted or no opening exists through modified openings (4534) in which a part of the opening (4531) is removed.

[0082] Referring to FIG. 7b, in order to reinforce the rigidity of the upper portion of the conductive plate (450), the upper region of the flexible portion (453) may be formed to have a third gap (d3) wider than the surroundings by arranging one opening (4531) alternately in the second direction (e.g., x-axis direction) of the flexible portion (453).

[0084] Referring to FIG. 7c, to reinforce the rigidity of the upper portion of the conductive plate (450), the upper region of the flexible portion (453) may be arranged such that two openings (4531) are omitted alternately in the second direction (e.g., x-axis direction) of the flexible portion (453), or formed to have a fourth gap (d4) wider than the surroundings through modified openings (4534) in which a part of the opening (4531) is removed.

In another embodiment, the cross-sectional shape of the flexible portion (453) may be formed into a circular or elliptical shape. For example, if the cross-section of the flexible portion (453) is formed into a circular, elliptical, or polygonal shape, it may help to relieve stress generated by the folding or unfolding motion of the electronic device and to reduce the repulsive force caused by bending.

[0093] FIGS. 8a to 8c are drawings illustrating various shapes of openings (4535, 4536, 4537) according to various embodiments of the present invention.

[0094] As illustrated in FIGS. 8a through 8c, the flexible portion (453) of the conductive plate (450) may be replaced with openings of various shapes (4535, 4536, 4537) that are perforated, in addition to the elliptical openings (e.g., the openings (4531) of FIG. 6a) that extend in the first direction (y-axis direction) as described above. For example, the openings (4535, 4536, 4537) may include circular openings (4535), square openings (4536), and / or rhombus-shaped openings (4537) that are arranged regularly or irregularly in the first direction (y-axis direction) and / or the second direction (x-axis direction) of the flexible portion (453). In addition, various other shapes of openings may be formed. In another embodiment, the openings may be arranged to have at least partially different shapes.

[0096] FIGS. 9a and 9b are drawings illustrating various variations of the region C1 of FIG. 5 according to various embodiments of the present invention.

[0097] The flexible portion (453) of the conductive plate (450) according to various embodiments of the present invention may further include rigidity reinforcing portions (B2, B3) that are at least partially disposed in the upper portion and / or lower portion as well as in other portions, as described above. Furthermore, the illustrated rigidity reinforcing portions (B2, B3) may be disposed in at least one portion of the flexible portion (453) other than the C1 portion.

[0098] Referring to FIG. 9a, the flexible portion (453) of the conductive plate (450) may include a plurality of openings (4531) spaced apart from each other along a first direction (y-axis direction) and / or a second direction (x-axis direction). According to one embodiment, the flexible portion (453) may include a rigidity reinforcing portion (B2) in which the openings (4531) are omitted along the second direction (x-axis direction). According to one embodiment, the rigidity reinforcing portion (B2) may not only firmly support the display panel (e.g., the display panel (430) of FIG. 4b) on the back of the display (e.g., the display (400) of FIG. 4b) but may also determine the flexibility of the flexible portion (453). According to one embodiment, the rigidity reinforcing portion (B2) may be placed in various regions of the flexible portion (453). According to one embodiment, the flexibility of the flexible portion (453) may be determined by the number of rigidity reinforcing portions (B2) and / or the spacing distance (d7) between the surrounding openings (4531) by the rigidity reinforcing portions (B2).

[0099] Referring to FIG. 9b, the flexible portion (453) of the conductive plate (450) may include a plurality of openings (4531) spaced apart from each other along a first direction (y-axis direction) and / or a second direction (x-axis direction). According to one embodiment, the flexible portion (453) may include a rigidity reinforcement portion (B3) in which the openings (4531) are omitted along the second direction (x-axis direction). According to one embodiment, the density of the openings (4531) placed in the rigidity reinforcement portion (B3) may be adjusted to be lower than the density of the openings (4531) placed in the surrounding area, thereby helping to reinforce rigidity and / or control flexibility. According to one embodiment, the flexibility of the flexible portion (453) may be determined by the number of rigidity reinforcing portions (B3), the arrangement density of the openings (4531), and / or the spacing distance (d8) between the openings (4531) around the rigidity reinforcing portions (B3).

[0101] FIG. 10 is a diagram illustrating the arrangement configuration of openings (4531) considering the regional bending of the flexible portion (453) of the conductive plate (450) according to the folding operation of the display (400) according to various embodiments of the present invention.

[0102] Referring to FIG. 10, the flexible portion (453) of the conductive plate (450) can have its bending characteristics adjusted by region. According to one embodiment, when the first planar portion (451) and the second planar portion (452) are folded so as to face each other (in-folded state), the flexible portion (453) can be bent with different radii of curvature depending on the region, and the resulting bending characteristics can be applied differently. This is because, in regions where excessive bending is not required, the number of openings (4531) can be reduced to help reinforce rigidity. For example, as illustrated, when the first planar section (451) and the second planar section (452) are folded to face each other, it may be advantageous to determine that the flexibility of the first bending region (B4) of the flexible section (453) located furthest from the first planar section (451) and the second planar section (452) is greater than the flexibility of the second bending region (B5) of the flexible section (453) located close to the first planar section (451) and the second planar section (452). Accordingly, by setting the arrangement density of the plurality of openings (4531) in the first bending region (B4) to be higher than the arrangement density of the plurality of openings (4531) in the second bending region (B5), the bending characteristics of the flexible section (453) can be adjusted by region. In another embodiment, for a second bending area (B5) where relatively less flexibility is required, the opening (4531) may be formed thinner and shorter than in the first bending area (B4), or the placement density may be reduced to increase the attachment surface and secure rigidity. In another embodiment, for a first bending area (B4) where relatively more flexibility is required, the opening (4531) may be formed thicker and longer than in the second bending area (B5), or the placement density may be increased to reduce the attachment surface. In another embodiment, when the display (400) is in an out-folding form where the first flat portion (451) and the second flat portion (452) are folded in opposite directions, the placement density of the plurality of openings (4531) in the first bending area (B4) may be set lower than the placement density of the plurality of openings (4531) in the second bending area (B5).In another embodiment, the regional bending characteristics of the flexible part (453) may be determined in addition to adjusting the arrangement density of the plurality of openings (4531), by changing the shape of the plurality of openings (4531), adjusting the spacing between the openings (4531) in a first direction (y-axis direction) and / or a second direction (x-axis direction), or by partially arranging at least one area in which the openings (4531) are omitted. In another embodiment, when a plurality of curvature values ​​are formed in the flexible part (453), the design may be configured by adjusting the density of the openings (4531) according to the curvature values. In particular, flexibility and rigidity can be controlled by setting the density of the openings low when the curvature value is large and setting the density of the openings high when the curvature value is small.

[0103] In another embodiment, a flexible display (400) comprising a foldable conductive plate (450) according to exemplary embodiments of the present invention may be applied to a foldable electronic device that operates in-folding and / or out-folding in a range of 0 to 360 degrees. In another embodiment, a flexible display (400) comprising a foldable conductive plate (450) according to exemplary embodiments of the present invention may be applied to a multi-foldable electronic device that operates in a multi-folding manner in which a plurality of housings (e.g., three or more housings) are configured to be folded alternately in opposite directions relative to each other. In another embodiment, a flexible display (400) comprising a foldable conductive plate (450) according to exemplary embodiments of the present invention may also be applied to a rollable electronic device configured to allow selective expansion of the display area by enabling a second housing to slide at least partially from a first housing. For example, a flexible display (400) including a foldable conductive plate (450) according to exemplary embodiments of the present invention can be applied to various deformable electronic devices in which the shape and / or display area of ​​the display is correspondingly changed through an operational change of at least one housing.

[0105] According to exemplary embodiments of the present invention, a conductive plate may be attached to a polymer layer through an adhesive member. In this case, the adhesive member may further include an additional structure to prevent the adhesive member from entering the openings or to prevent a decrease in flexibility due to the adhesive force in the area surrounding the openings.

[0106] FIG. 11a is a cross-sectional view illustrating a stacked structure of a display (400) according to various embodiments of the present invention. FIG. 11b is a partial perspective view of a conductive plate (450) illustrating a state in which a filling member (460) is applied to a flexible part (453) according to various embodiments of the present invention.

[0107] Referring to FIGS. 11a and 11b, the display (400) may include a filling member (460) that is filled into a plurality of openings (4531) formed in the flexible portion (453) of the conductive plate (450). According to one embodiment, the flexible portion (453) of the conductive plate (450) may be formed to have a flat surface with respect to the adhesive member (P3) on the front side through the filling member (460) and may also be formed to have a flat surface on the rear side. According to one embodiment, the filling member (460) may include an elastic material that hardens and / or solidifies after being filled into the plurality of openings (4531) of the flexible portion (453) of the conductive plate (450). According to one embodiment, the filling member (460) may include resin, urethane, silicone, or rubber.

[0108] According to various embodiments, when a conductive plate (450) filled with a plurality of openings (4531) through a filling member (460) is attached to a polymer member (440) through an adhesive member (P3), it may help prevent a decrease in flexibility and visibility of the openings caused by the inflow of the openings (4531) of the adhesive member (P3).

[0110] FIG. 12a is a cross-sectional view illustrating a stacked structure of a display (400) according to various embodiments of the present invention. FIG. 12b is a partial perspective view illustrating a state in which a film member (470) is applied between a conductive plate (450) and an adhesive member (P3) according to various embodiments of the present invention.

[0111] Referring to FIGS. 12a and 12b, the display (400) may include a film member (e.g., TPU (thermoplastic polyurethane), 470) disposed between a conductive plate (450) and an adhesive member (P3). According to one embodiment, the film member (470) may be formed to a size that covers the first planar portion (451) and the second planar portion (452), including the flexible portion (453) of the conductive plate (450). In another embodiment, the film member (470) may be formed to a size that covers only the flexible portion (453) of the conductive plate (450). According to one embodiment, the film member (470) may prevent the phenomenon of the adhesive member (P3) being visible from the front of the display (400) by being introduced into a plurality of openings (4531). In another embodiment, instead of a film member (470), a printing area may be included that is positioned between a conductive plate (450) and an adhesive member (P3). According to one embodiment, if the film member (470) and / or the printing area is applied only to the flexible portion (453), the adhesive force of the adhesive member (P3) to the flexible portion (453) is excluded or weakened, thereby preventing the deterioration of the bending characteristics of the flexible portion (453) due to the adhesive force of the adhesive member.

[0112] According to various embodiments, although not illustrated, the adhesive member (P3) of the display (400) may be arranged such that the area overlapping with the flexible portion (453) is omitted when the display is viewed from above. In another embodiment, the adhesive member (P3) may prevent the inflow of the adhesive member (P3) into the multiple openings (4531) of the flexible portion (453) by setting the modulus characteristics of the area overlapping with the flexible portion (453) and the area overlapping with the first planar portion (451) and the second planar portion (452) differently when the display (400) is viewed from above. For example, in the case of the adhesive member (P3) corresponding to the flexible portion (453), an adhesive member having soft type properties may be applied. In the case of such adhesive members, a (meth)acrylate copolymer such as (meth)acrylate or urethane acrylate, or a silicone copolymer such as (dimethyl)siloxane may be used. According to one embodiment, for the adhesive member (P3) corresponding to the flexible portion (453), an adhesive member with a modulus characteristic of less than 5 × 10⁵ Pascal (Pa) may be applied. According to one embodiment, for the adhesive member (P3) corresponding to the first planar portion (451) and the second planar portion (452), an adhesive member with hard type properties may be applied. In the case of such adhesive members (P3), a (meth)acrylate copolymer such as (meth)acrylate or urethane acrylate, or a silicone copolymer such as (dimethyl)siloxane may be used. According to one embodiment, for the adhesive member corresponding to the first planar portion (451) and the second planar portion (452), an adhesive member having a modulus characteristic of 5×105 Pascal (Pa) or higher may be applied.

[0114] FIG. 13a is a diagram showing the configuration of a conductive plate (450) according to various embodiments of the present invention. FIG. 13b is an enlarged view of a part of region C6 and region C7 of FIG. 13a according to various embodiments of the present invention.

[0115] Referring to FIGS. 13a and FIGS. 13b, the conductive plate (450) may include a first planar portion (451) facing a first area (e.g., the first area (h1) of FIG. 4b) of a display (e.g., the display (400) of FIG. 4b), a second planar portion (452) facing a second area (e.g., the second area (h2) of FIG. 4b) of the display (400), and a flexible portion (453) facing a third area (e.g., the third area (h3) of FIG. 4b) of the display (400). According to one embodiment, the flexible portion (453) may include an area in which a plurality of openings (4531) are formed. According to one embodiment, the flexible portion (453) may substantially include a bending portion (453a) that bends together when the first housing structure (e.g., the first housing structure (110) of FIG. 1) and the second housing structure (e.g., the second housing structure (120) of FIG. 1) are in a folded state, a first lower attachment portion (453b) connected from the bending portion (453a) to the first planar portion (451), and a second lower attachment portion (453c) connected from the bending portion (453a) to the second planar portion (452). According to one embodiment, the first lower attachment portion (453b) and the second lower attachment portion (453c) are areas formed by extending a plurality of openings (4531) from the bending portion (453a), and can be attached, for example, to the first housing structure (110) and the second housing structure (120) through an adhesive member. According to one embodiment, the stress concentration phenomenon caused by the bending of the bending portion (453a) can be relieved through an attachment structure in which the first lower attachment portion (453b) and the second lower attachment portion (453c), with the plurality of openings (4531) extended therefrom, are attached to the housing structures (110, 120).

[0116] According to various embodiments, the conductive plate (450) may include a first rigidity reinforcement area (C7) and a second rigidity reinforcement area (C8) disposed in upper and lower regions of the flexible portion (453) where fatigue may accumulate relatively significantly due to frequent folding movements. According to one embodiment, the flexible portion (453) may include a general folding area (C6) extending from the first rigidity reinforcement area (C7) to the second rigidity reinforcement area (C8).

[0117] According to various embodiments, the flexible portion (453) may include rigidity reinforcing portions (4532) formed to have a relatively large width (t1) by omitting at least some of the plurality of openings (4531) arranged in the second direction (x-axis direction) in the first rigidity reinforcing area (C7), so that the gap between one opening (4531a) and another adjacent opening (4531b) is greater than the gap between the openings (4531) arranged in the general folding area (C6). According to one embodiment, the rigidity reinforcing portion (4532) may be formed by omitting one, two, three, or more openings between one opening (4531a) and another adjacent opening (4531b). Although not illustrated, the second rigidity reinforcing area (C8) may also have substantially the same configuration as the first rigidity reinforcing area (C7).

[0118] According to various embodiments, the flexible portion (453) may have at least partially adjustable flexibility in a general folding area (C6). According to one embodiment, the bending portion (453a) of the flexible portion (453) may have at least partially adjustable flexibility in a general folding area (C6). According to one embodiment, the flexible portion (453) may have adjustable flexibility in a general folding area (C6) by forming different lengths of openings (4531) arranged along a first direction (y-axis direction). For example, the flexible portion (453) may include a plurality of openings (4531) arranged side by side along the first direction (y-axis direction) in the same manner as a first opening (4531-1) having a first length (l1) arranged along the first direction (y-axis direction) in a general folding area (C6), a second opening (4531-2) having a second length (l2) longer than the first length (l1) arranged along the same axis (y-axis) as the first opening (4531-1), and a third opening (4531-3) having a third length (l3) longer than the second length (l2) arranged along the same axis (y-axis) as the second opening (4531-2). In this case, the openings (4531) may be arranged such that they have equal spacing in the second direction (x-axis direction) (e.g., spacing (d1) in FIG. 6a), equal spacing in the first direction (y-axis direction) (e.g., spacing (d2) in FIG. 6a), and equal width (e.g., width (w) in FIG. 6a), with only the length (e.g., length (l) in FIG. 6a) changing. For example, since there may be a limit to reducing the size of the width (e.g., width (w) in FIG. 6a) of the fine openings (4531), it may be advantageous to control the bending characteristics of the flexible part (453) by adjusting the length while maintaining a relatively equal width. According to one embodiment, the openings (4531) arranged such that their length gradually increases along the first direction (y-axis direction) may also be arranged along the second direction (x-axis direction) in the same manner.In another embodiment, the length of the openings (4531) may be formed such that they gradually decrease in length or gradually increase in length from the first rigidity reinforcement area (C7) and the second rigidity reinforcement area (C8) toward the center of the general folding area (C6). In another embodiment, the length of the openings (4531) may be formed such that they gradually decrease in length or gradually increase in length from the first rigidity reinforcement area (C7) toward the second rigidity reinforcement area (C8). In another embodiment, the plurality of openings (4531) may be arranged so that their length gradually increases or decreases in a second direction (x-axis direction) perpendicular to the first direction (y-axis direction). In this case, the plurality of openings (4531) may be arranged such that, in the flexible portion (453), their length increases as they proceed from the edge near the first planar portion (451) and the second planar portion (452) toward the center in the second direction (x-axis direction). This is because relatively large bending properties are required as the flexible portion (453) proceeds from the first planar portion and the second planar portion to the central portion. In other words, this means that the bending properties of the flexible portion (453) can be adjusted to have relatively high rigidity as it proceeds from the central portion of the bending portion (453a) to the first lower attachment portion (453b) and the second lower attachment portion (453c). In another embodiment, the length of the openings (4531) may be formed so that their length gradually shortens or gradually lengthens along the first direction (y-axis direction) and / or the second direction (x-axis direction) only in at least partially defined portions of the general folding area (C6). In another embodiment, the length of the openings (4531) may not change gradually but change irregularly.

[0120] FIG. 14a is a partial cross-sectional view illustrating a stacked structure of a display (1400) according to various embodiments of the present invention.

[0121] The display (1400) of FIG. 14a may include at least some similarities to the display (130) of FIG. 3 or other embodiments of the display.

[0122] Referring to FIG. 14a, the display (1400) may include a display panel (430), at least one polymer member (440) sequentially disposed on the display panel (430), a conductive plate (450), and a blocking member (475) (e.g., TPU, silicone, rubber, or urethane) disposed to block a flexible portion (453) in which a plurality of openings (4531) of the conductive plate (450) are formed. According to one embodiment, the display (1400) may be disposed to cross at least a portion of a first surface (e.g., the first surface (111) of FIG. 1) of a first housing structure (110) (e.g., the first housing structure (110) of FIG. 1) and a third surface (e.g., the third surface (121) of FIG. 1) of a second housing structure (120) (e.g., the second housing structure (120) of FIG. 1). According to one embodiment, the display (1400) may include a first region (h1) which is a planar area corresponding to a first housing structure (110) of an electronic device (e.g., electronic device (100) of FIG. 1), a second region (h2) which is a planar area corresponding to a second housing structure (120), and a third region (h3) which faces a hinge structure (e.g., hinge structure (164) of FIG. 3). According to one embodiment, the first region (h1) and the second region (h2) of the display (1400) may be configured to be foldable or unfoldable relative to each other with respect to at least a portion of the third region (h3). According to one embodiment, the conductive plate (450) may include a flexible portion (453) corresponding to the third region (h3) of the display (1400). According to one embodiment, the flexible portion (453) may include a foldable bending portion (453a) and a first lower attachment portion (453b) and a second lower attachment portion (453c) that extend to both sides of the bending portion (453a) and are respectively connected to a first planar portion (451) and a second planar portion (452).

[0123] According to various embodiments, at least one polymer member (440) may include a cushion layer (441) and a first layer (442) and a second layer (443) laminated between the cushion layer (441). According to one embodiment, at least one polymer member (440) may have a laminated structure to block the ingress of foreign substances through a plurality of openings (4531) formed in the flexible portion (453) of the conductive plate (450) and to prevent visibility of the fold boundary area of ​​the display (1400) due to the folding and unfolding operation of the electronic device. According to one embodiment, the cushion layer (441) may be formed of a material for cushioning (e.g., sponge or poron). According to one embodiment, the first layer (442) placed on top of the cushion layer and the second layer (443) placed on bottom of the cushion layer (441) may be formed of a material for surface quality improvement (visibility improvement) (e.g., TPU). According to one embodiment, the surface roughness (e.g., surface roughness) of the first layer (442) and the surface roughness of the second layer (443) may be the same or different from each other. For example, to improve visibility, the surface roughness of the first layer may be formed to be lower than the surface roughness of the second layer (443).

[0124] According to various embodiments, a display panel (430), at least one polymer member (440), a conductive plate (450), and a blocking member (475) may be attached to each other through adhesive members (551, 552, 553, 554). For example, the adhesive members (551, 552, 553, 554) may include at least one of an optical clear adhesive (OCA), a pressure-sensitive adhesive (PSA), a thermoreactive adhesive, a general adhesive, or double-sided tape. According to one embodiment, at least one polymer member (440) may be attached to the back surface of the display panel (430) through a first adhesive member (551). According to one embodiment, the conductive plate (450) may be attached to the back surface of the polymer member (440) through a second adhesive member (552). According to one embodiment, the blocking member (475) may be attached to the back surface of the conductive plate (450) through the third adhesive member (553). According to one embodiment, the display (1400) may be attached at least partially to the first housing structure (110) and the second housing structure (120) through the fourth adhesive member (554) and the fifth adhesive member (555).

[0125] According to various embodiments, the blocking member (475) may be attached to the first housing structure (110) and the second housing structure (120) at least partially through the fourth adhesive member (554). According to one embodiment, the blocking member (475) may be attached to the first housing structure (110) and the second housing structure (120) through the fourth adhesive member (554), including the first lower attachment part (453b) and the second lower attachment part (453c), except for the area that overlaps with the bending part (453a) of the flexible part (453) when the display is viewed from above. This may be intended to provide a non-adhesive section in the area of ​​the blocking member (475) corresponding to the bending section (453a), thereby relieving the stress concentration phenomenon caused by the folding operation and allowing the first housing structure (110) and the second housing structure (120) to be separated from the surface of the display (1400) during the folding operation. In another embodiment, the non-adhesive section may be arranged to overlap with an area that is larger than the bending section (453a) and smaller than the flexible section (453) when the display (1400) is viewed from above. In another embodiment, the non-adhesive section may be arranged to overlap with an area that is larger than the flexible section (453) when the display (1400) is viewed from above. According to one embodiment, the conductive plate (450) may be directly attached to the first housing structure (110) and the second housing structure (120) via a fifth adhesive member (555) in the edge area excluding the blocking member (475). According to one embodiment, the fifth adhesive member may be formed with a thickness to compensate for the thickness of the third adhesive member (553), the blocking member (475), and the fourth adhesive member (554). According to one embodiment, the fifth adhesive member (555) may include double-sided tape or waterproof tape.

[0127] FIG. 14b is a partial cross-sectional view of a display (1400) showing a folded structure of a conductive plate in a folded state according to various embodiments of the present invention.

[0128] Referring to FIG. 14b, the conductive plate (450) may include a first planar portion (451) that is at least partially attached to a first housing structure (110), a second planar portion (452) that is at least partially attached to a second housing structure (120), and a flexible portion (453) that connects the first planar portion (451) and the second planar portion (452) and is provided with at least partial flexibility through a plurality of openings (4531). According to one embodiment, the flexible portion (453) may include a bending portion (453a) that bends together when the display (1400) is folded, a first lower attachment portion (453b) extending from the bending portion (453a) to a first planar portion (451), and a second lower attachment portion (453c) extending from the bending portion (453a) to a second planar portion (452). According to one embodiment, in order to resolve the stress concentration phenomenon occurring near each planar portion (451, 452) according to the folding operation of the conductive plate (450), the first lower attachment portion (453b) and the second lower attachment portion (453c) may be attached to the first housing structure (110) and the second housing structure (120). For example, if the flexible part (453) aligns with the bending part (453a), stress is concentrated at both ends of the bending part (453a), and a problem may occur in which parts connected to the opening (4531) in that area are severed depending on the folding or unfolding motion of the electronic device. Therefore, the stress concentrated in the stress concentration area depending on the folding or unfolding motion of the electronic device can be relieved through the first lower attachment part (453b) and the second lower attachment part (453c), which are extended from the bending part (453a) through the extension formation of the openings (4531) and at least partially attached to the first housing structure (110) and the second housing structure (120).

[0129] According to various embodiments, the area of ​​the first lower attachment portion (453b) and the second lower attachment portion (453c) may be determined from the bending portion (453a) to the point where the last opening (4531) located at both left and right ends of the flexible portion (453) ends, the point where the last opening (4531) ends and at least partially includes at least a part of the first planar portion (451) and the second planar portion (452), or a point that includes a part of the last opening (4531).

[0131] FIG. 15a is a configuration diagram showing the rear view of a display (1500) according to various embodiments of the present invention. FIG. 15b is a diagram showing a state in which a first reinforcing plate (510) and a second reinforcing plate (520) are arranged close to each other according to various embodiments of the present invention.

[0132] The display (1500) of FIG. 15a may include at least some similarities to the display (130) of FIG. 3 or other embodiments of the display.

[0133] In describing FIGS. 15a and FIGS. 15b, at least some of the configurations of the display (1500) may be substantially the same as the configuration of FIG. 4c, and the same reference numerals may be assigned to identical components, and redundant descriptions may be omitted.

[0134] Referring to FIGS. 15a and 15b, the display (1500) may include a pair of reinforcing plates (510, 520) that can help reinforce the rigidity of the display (1500) by being disposed on the back surface of the conductive plate (450). According to one embodiment, the pair of reinforcing plates (510, 520) may include a first reinforcing plate (510) disposed to extend from at least a part of the first planar portion (451) of the conductive plate (450) to at least a part of the flexible portion (453), and a second reinforcing plate (520) disposed to extend from at least a part of the second planar portion (452) of the conductive plate (450) to at least a part of the flexible portion (453). According to one embodiment, the first reinforcing plate (510) and the second reinforcing plate (520) may be formed in a shape that avoids structures disposed on the back surface of the conductive plate (450). For example, the first reinforcing plate (510) and the second reinforcing plate (520) may be formed in a shape that avoids an adhesive member (P4) disposed along the edge of the back surface of the conductive plate (450). According to one embodiment, the first reinforcing plate (510) and the second reinforcing plate (520) may be formed in a shape that avoids an extension (431), a connecting pad (434), and an FPCB (432) that are folded from a display panel (e.g., the display panel (430) of FIG. 4c) and disposed on the back surface of the conductive plate (450). This may be to prevent an increase in the thickness of the display (1500) due to the stacking of the reinforcing plates (510, 520).

[0135] According to various embodiments, the first reinforcing plate (510) and the second reinforcing plate (520) may be arranged in the flexible portion of the conductive plate (450) to have spaced gaps (g1, g2, g3) that are at least partially different from each other with respect to axis A. These gaps (g1, g2, g3) may be implemented so that when the display (1500) is folded with respect to the flexible portion (453), the first reinforcing plate (510) and the second reinforcing plate (520) also fold together with the first planar portion (451) and the second planar portion (452) of the conductive plate (450).

[0136] According to various embodiments, the first reinforcing plate (510) and the second reinforcing plate (520) may be arranged to face each other with a first gap (g1) over substantially most of the area. According to one embodiment, the first reinforcing plate (510) may include a first extension (511) and a second extension (512) to cover the upper area (C8 area) and the lower area (C9 area) of the flexible portion (453) of the conductive plate (450). According to one embodiment, the second reinforcing plate (520) may include a third extension (521) and a fourth extension (522) to cover the upper area (C8 area) and the lower area (C9) of the flexible portion (453) of the conductive plate (450). According to one embodiment, the first extension (511) and the third extension (521) may be arranged to face each other with a second gap (g2) smaller than the first gap (g1). According to one embodiment, the second extension (512) and the fourth extension (522) may also be arranged to face each other with a second gap (g2). According to one embodiment, the first reinforcing plate (510) and the second reinforcing plate (520) may be arranged to have a third gap (g3) larger than the first gap (g1) in at least some areas facing each other. Through an area having a relatively large third gap (g3), an electrical connection member (e.g., FPCB) (e.g., at least one wiring member (163) of FIG. 3) can be provided for placement space extending from the first internal space of the first housing structure (110) of the electronic device through a hinge structure to the second internal space of the second housing structure (120).
