Description

[0001] This application is a divisional application of Chinese Patent Application No. 202080001213.X, entitled "Electronic Device Including Foldable Conductive Plate", filed on March 11, 2020. Technical Field

[0002] Various embodiments of this disclosure relate to electronic devices including foldable conductive plates. Background Technology

[0003] As the functional differences between manufacturers significantly decrease, electronic devices are becoming increasingly thinner to meet consumer demands. Improvements are being made to electronic devices to increase their rigidity, enhance their design, and differentiate their functional components. Such devices are gradually shifting from a uniform rectangular shape to various other forms. For example, electronic devices are becoming more portable and feature deformable structures that can be used with large-screen displays. Foldable electronic devices have been continuously released, and the support structures for foldable displays are also being improved. Summary of the Invention

[0004] Technical issues The foldable electronic device may include a hinge structure and a first housing structure and a second housing structure connected in opposite directions within the hinge structure. The foldable electronic device can operate in an inward and / or outward folding manner when the first housing structure rotates relative to the second housing structure via the hinge structure in a range of 0º to 360º. The foldable electronic device may include a flexible display arranged to span the first and second housing structures in an unfolded state of 180º.

[0005] Typically, electronic devices with a single housing (e.g., strip-type electronic devices) may include at least one conductive plate disposed on the rear surface of a display within an internal space. This conductive plate can help enhance rigidity by supporting the display and can also be used for noise shielding. Such a conductive plate can be grounded to the ground of a printed circuit board disposed inside the electronic device via an electrical connection member.

[0006] Foldable electronic devices can have a configuration in which a first housing structure and a second housing structure move relative to each other and are separated from each other by a hinge structure. Therefore, in cases where the conductive plates cannot be folded, two conductive plates can be arranged separately in each housing structure.

[0007] However, due to the frequent folding operations of electronic devices, this individual arrangement of conductive plates causes folding marks in the corresponding parts of the display facing the corners of each conductive plate near the hinge structure, and these folding marks may cause malfunctions of electronic devices and reduce operational reliability.

[0008] Various embodiments of this disclosure can provide an electronic device including a foldable conductive plate.

[0009] Various embodiments of this disclosure can provide an electronic device including a flexible foldable conductive plate in each region that can be adjusted according to folding characteristics.

[0049] Figure 1 This is a view showing an electronic device in a flat state according to an embodiment of the present disclosure. Figure 2 This is a view showing an electronic device in a folded state according to an embodiment of the present disclosure.

[0050] refer to Figure 1 The electronic device 100 may include a hinge structure (e.g., Figure 3 The device comprises a hinge structure 164 rotatably coupled to a pair of housing structures 110 and 120 folded relative to each other, a hinge cover 165 covering the foldable portions of the housing structures 110 and 120, and a display 130 (e.g., a flexible display or a foldable display) disposed in the space formed by the housing structures 110 and 120. In the description, the surface on which the display 130 is disposed may be referred to as the front surface of the electronic device 100, and the opposite side of the front surface may be referred to as the rear surface of the electronic device 100. The surface surrounding the space between the front and rear surfaces may be referred to as the side surface of the electronic device 100.

[0051] In one embodiment, the pair of housing structures 110 and 220 may include a first housing structure 110, a second housing structure 120, a first rear cover 140, and a second rear cover 150, wherein the first housing structure 110 includes a sensor region 131d. The pair of housing structures 110 and 120 of the electronic device 100 are not limited to... Figure 1 and Figure 2 The shape or combination shown is not the only one that can be achieved; rather, it can be implemented in various shapes or combinations. For example, in another embodiment, the first housing structure 110 and the first rear cover 140 can be formed as a single body, and the second housing structure 120 and the second rear cover 150 can be formed as a single body.

[0052] In one embodiment, the first housing structure 110 and the second housing structure 120 may be arranged on opposite sides of the folding axis (A) and may be substantially symmetrical with respect to the folding axis (A). In one embodiment, the angle or distance between the first housing structure 110 and the second housing structure 120 may vary depending on whether the electronic device 100 is in a flat or closed state, a folded state, or an intermediate state. In one embodiment, the first housing structure 110 includes a sensor region 131d in which various sensors are arranged, but may have a shape symmetrical to the second housing structure 120 in other regions. In another embodiment, the sensor region 131d may be arranged in a specific region of the second housing structure 120 or may be replaced.

[0053] In one embodiment, during the flat state of the electronic device 100, the first housing structure 110 may be connected to a hinge structure (e.g., Figure 3 The hinge structure 164 may include a first surface 111 facing the front surface of the electronic device 100, a second surface 112 facing away from the first surface 111, and a first side member 113 surrounding 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 surface 113a arranged parallel to the folding axis (A), a second side surface 113b extending from one end of the first side surface 113a in a direction perpendicular to the folding axis, and a third side surface 113c extending from the other end of the first side surface 113a in a direction perpendicular to the folding axis.

[0054] In one embodiment, during the flat state of the electronic device 100, the second housing structure 120 may be connected to a hinge structure (e.g., Figure 3 The hinge structure 164 may include a third surface 121 facing the front surface of the electronic device 100, a fourth surface 122 facing away from the third surface 121, and a second side member 123 surrounding 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 surface 123a arranged parallel to the folding axis (A), a fifth side surface 123b extending from one end of the fourth side surface 123a in a direction perpendicular to the folding axis, and a sixth side surface 123c extending from the other end of the fourth side surface 123a in a direction perpendicular to the folding axis. In one embodiment, the third surface 121 may face the first surface 111 in the folded state.

[0055] In one embodiment, the electronic device 100 may include a recess 101 formed to accommodate a display 130 by a structural combination of the shapes of a first housing structure 110 and a second housing structure 120. The recess 101 may have substantially the same dimensions as the display 130. In one embodiment, due to the sensor region 131d, the recess 101 may have two or more different widths in a direction perpendicular to the folding axis (A). For example, the recess 101 may have a first width (W1) between a first portion 120a of the second housing structure 120 parallel to the folding axis (A) and a first portion 110a of the first housing structure 110 formed at the edge of the sensor region 131d, and a second width (W2) between a second portion 120b of the second housing structure 120 and a second portion 110b of the first housing structure 110 that does not correspond to the sensor region 131d and is parallel to the folding axis (A). Here, the second width (W2) may be wider than the first width (W1). In other words, the recess 101 can be formed with a first width (W1) (asymmetrical shape) from the first portion 110a of the first housing structure 110 to the first portion 120a of the second housing structure 120, and a second width (W2) (symmetrical shape) from the second portion 110b of the first housing structure 110 to the second portion 120b of the second housing structure 120. In one embodiment, the first portion 110a and the second portion 110b of the first housing structure 110 can be located at different distances from the folding axis (A). The width of the recess is not limited to the example shown above. In various embodiments, due to the shape of the sensor region 131d or the asymmetry of the first housing structure 110 or the second housing structure 120, the recess 101 can have two or more different widths.

[0056] In one embodiment, at least a portion of the first housing structure 110 and the second housing structure 120 may be made of a metallic or non-metallic material having a stiffness value selected to support the display 130.

[0057] In one embodiment, sensor region 131d may be formed with a predetermined area near one corner of the first housing structure 110. However, the arrangement, shape, or size of sensor region 131d is not limited to the example shown. For example, in a particular embodiment, sensor region 131d may be formed at another corner of the first housing structure 110, or in any area between the upper and lower corners. In another embodiment, sensor region 131d may be arranged on a portion of the second housing structure 120. In another embodiment, sensor region 131d may be formed to extend between the first housing structure 110 and the second housing structure 120. In one embodiment, to perform various functions, electronic device 100 may include components exposed to the front surface of electronic device 100 through sensor region 131d or through one or more openings arranged in sensor region 131d. These components may include at least one of, for example, a front camera, a receiver, a proximity sensor, an illumination sensor, an iris recognition sensor, an ultrasonic sensor, or an indicator.

[0058] In one embodiment, the first rear cover 140 may be disposed on the second surface 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 enclosed by the first housing structure 110. Similarly, the second rear cover 150 may be disposed on the fourth surface 122 of the second housing structure 120, and at least a portion of its periphery may be enclosed by the second housing structure 120.

[0059] In the illustrated embodiment, the first rear cover 140 and the second rear cover 150 may have a shape that is substantially symmetrical with respect to the folding axis (A). In another embodiment, the first rear cover 140 and the second rear cover 150 may have various different shapes. In yet another embodiment, the first rear cover 140 may be formed as a single body with the first housing structure 110, and the second rear cover 150 may be formed as a single body with the second housing structure 120.

[0060] 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 with each other to provide space for various components of the electronic device 100, such as printed circuit boards, antenna modules, sensor modules, and batteries. In one embodiment, one or more components may be disposed on or visible through the rear surface of the electronic device 100. For example, one or more components or sensors may be visible through a first rear region 141 of the first rear cover 140. Sensors may include proximity sensors, rear cameras, and / or flashes. In another embodiment, at least a portion of the sub-display 152 may be visible through a second rear region 151 of the second rear cover 150.

[0061] Electronic device 100 can be arranged in the space formed by a pair of housing structures 110 and 120. For example, electronic device 100 can be disposed in a recess formed by a pair of housing structures 110 and 120 (e.g., Figure 1 The front surface of the electronic device 100 may be arranged in a recess 101, and may substantially occupy most of the front surface of the electronic device 100. Therefore, the front surface of the electronic device 100 may include a display 130, a portion of the first housing structure 110 near the display 130 (e.g., an edge region), and a portion of the second housing structure 120 near the display 130 (e.g., an edge region). In one embodiment, the rear surface of the electronic device 100 may include a first rear cover 140, a portion of the first housing structure 110 near the first rear cover 140 (e.g., an edge region), a second rear cover 150, and a portion of the second housing structure 120 near the second rear cover 150 (e.g., an edge region).

[0062] In one embodiment, display 130 may refer to a display whose at least a portion can deform into a flat or curved surface. In one embodiment, display 130 may include a folded region 131c, a first region 131a disposed on one side (e.g., the right side of folded region 131c) relative to folded region 131c, and a second region 131b disposed on the other side (e.g., the left side of folded region 131c). For example, the first region 131a may be disposed on a first surface 111 of the first housing structure 110, and the second region 131b may be disposed on a third surface 121 of the second housing structure 120. This division of display 130 is merely an example, and display 130 may be subdivided into multiple regions (e.g., four or more regions) depending on its structure or function. For example, in Figure 1 In one embodiment, the area of ​​display 130 can be subdivided relative to the folding region 131c or a folding axis (A) extending parallel to the y-axis. However, in another embodiment, the area of ​​display 130 can be subdivided relative to different folding regions (e.g., folding regions parallel to the x-axis) or different folding axes (e.g., folding axes parallel to the x-axis). The aforementioned subdivision of the display is based solely on a pair of housing structures 110 and 120 and a hinge structure (e.g., Figure 3 The physical division of the hinge structure 164 in the display 130 can be achieved through a pair of housing structures 110 and 120 and a hinge structure (e.g., Figure 3 The hinge structure 164 in the middle essentially presents a full screen. In one embodiment, the first region 131a and the second region 131b may have a shape symmetrical with respect to the folding region 131c. Although the first region 131a may include a notched region cut according to the presence of the sensor region 131d (e.g., Figure 3The first region 131a may have a shape symmetrical to the second region 131b in other parts, while the second region 131a may have a notched region 133 in the notched region 133 in the notched region 131b. In other words, the first region 131a and the second region 131b may include parts with symmetrical shapes and parts with asymmetrical shapes.

[0063] refer to Figure 2 The hinge cover 165 can be disposed between the first housing structure 110 and the second housing structure 120 to cover internal components (e.g., Figure 3 (Hinge structure 164 in the embodiment). In one embodiment, the hinge cover 165 may be partially covered by the first housing structure 110 and the second housing structure 120, or exposed to the outside depending on the operating state of the electronic device 100 (e.g., flat or folded state).

[0064] For example, when electronic device 100 is in such a state Figure 1 In the flat state shown, the hinge cover 165 can be covered by the first housing structure 110 and the second housing structure 120, thus remaining unexposed. When the electronic device 100 is in such a flat state... Figure 2 In the folded state (e.g., fully folded state), the hinge cover 165 may be exposed outside the space between the first housing structure 110 and the second housing structure 120. When the electronic device 100 is in an intermediate state where the first housing structure 110 and the second housing structure 120 form an angle, the hinge cover 165 may be partially exposed outside the space between the first housing structure 110 and the second housing structure 120. In this case, the exposed portion may be smaller than the exposed portion in the fully folded state. In one embodiment, the hinge cover 165 may include a curved surface.

[0065] Next, based on the operating state of the electronic device 100 (e.g., flat state or folded state), the configuration of the first housing structure 110 and the second housing structure 120, as well as the description of the area of ​​the display 130, are given.

[0066] In one embodiment, when the electronic device 100 is in a flat state (e.g., Figure 1 When the first housing structure 110 and the second housing structure 120 are in the same state, they can form an angle of 180 degrees, and the first region 131a and the second region 131b of the display can be arranged to face the same direction. In addition, the folding region 131c can be coplanar with the first region 131a and the second region 131b.

[0067] In one embodiment, when the electronic device 100 is in a folded state (e.g., Figure 2When the display 130 is in a certain state, the first housing structure 110 and the second housing structure 120 can be arranged to face each other. The first region 131a and the second region 131b of the display 130 can face each other to form a narrow angle (e.g., between 0 degrees and 10 degrees). At least a portion of the folded region 131c can form a curved surface with a preset curvature.

[0068] In one embodiment, when the electronic device 100 is in an intermediate state, the first housing structure 110 and the second housing structure 120 can be arranged to form an angle. The first region 131a and the second region 131b of the display 130 can form an angle larger than the angle of the folded state but smaller than the angle of the flat state. At least a portion of the folded region 131c can form a curved surface with a preset curvature. This curvature can be smaller than the curvature of the folded state.

[0069] Figure 3 This is an exploded perspective view of an electronic device according to an embodiment of the present disclosure.

[0070] refer to Figure 3 In one embodiment, the electronic device 100 may include a display 130, a support component 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. In the description, the display 130 may be referred to as a display unit, display module, or display assembly.

[0071] The display 130 may include a display panel 131 (e.g., a flexible display panel) and at least one plate 132 or layer thereon on the display panel 131. In one embodiment, one or more plates 132 may include conductive plates (e.g., Cu sheets or SUS sheets) 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 the same as the area of ​​the display, and the region facing the folding area of ​​the display may be formed to be flexible. The plate 132 may include at least one auxiliary material layer (e.g., a graphite member) disposed on the rear surface of the display panel 131. In one embodiment, the plate 132 may be formed to correspond to the shape of the display panel 131. For example, a portion of the first plate 132 may be formed to correspond to the shape of a cutout region 133 of the display panel 131.

[0072] The support member assembly 160 may include: a first support member 161; a second support member 162; 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 a wiring member 163 (e.g., a flexible printed circuit board (FPCB)) intersecting the first support member 161 and the second support member 162.

Thus, when a pair of conductive plates are arranged separately based on a third region h3, fold marks on the display panel caused by the boundary edges of the conductive plates can be prevented by receiving the support of the flexible portion 453 of the exemplary integrated conductive plate 450 of this disclosure.

[0087] The structure of the conductive plate 450 will be described in detail below.

In another embodiment, the lightweight region 4511 (or lightweight region 4521) may include a plurality of notches formed at a predetermined depth, and the conductive plate is perforated in these notches. In this case, the lightweight level of the conductive plate can be determined based on the shape, depth, or size of the notches. According to one embodiment, the size or shape of the lightweight region 4511 can be determined without compromising the original functions such as the rigidity enhancement function, heat radiation function, and / or noise shielding function of the conductive plate 450.

Figures 7a to 7e Although a modified arrangement of the opening 4531 at the upper end of the conductive plate 450 is shown and described, the rigid reinforcement structure at the lower end of the conductive plate 450 may also have a substantially the same structure.

[0100] refer to Figure 7a For the upper end of the rigid reinforced conductive plate 450, the upper region of the flexible portion 453 may include a rigid reinforcement portion (part B1), which is formed such that there is no modified opening 4534 by removing some of the openings 4531 or by omitting all openings 4531 in a second direction (e.g., the x-axis direction).

[0101] refer to Figure 7b For the upper end of the rigid reinforced conductive plate 450, by omitting an opening 4531 alternately in the second direction (e.g., the x-axis direction) of the flexible portion 453, the upper region of the flexible portion 453 can be formed to have a third interval d3 that is wider than the periphery.

[0102] refer to Figure 7cFor the upper end of the rigid reinforced conductive plate 450, the upper region of the flexible portion 453 can be formed to have a fourth interval d4 that is wider than the periphery by either modifying the opening 4534 by removing a portion of the opening 4531 or by alternately omitting two openings 4531 in the second direction (e.g., the x-axis direction) of the flexible portion 453.

[0103] refer to Figure 7d For the upper end of the rigid reinforced conductive plate 450, the upper region of the flexible portion 453 can be formed to have a fifth interval d5 that is wider than the periphery by either modifying the opening 4534 by removing a portion of the opening 4531 or by omitting three openings 4531 alternately in the first direction (e.g., the x-axis direction) of the flexible portion 453.

[0104] refer to Figure 7e For the upper end of the rigid reinforced conductive plate 450, the upper region of the flexible portion 453 can be formed to have a sixth interval d6 that is wider than the periphery by either modifying the opening 4534 by removing a portion of the opening 4531 or by omitting four openings 4531 alternately in the first direction (e.g., the x-axis direction) of the flexible portion 453.

[0105] Figure 7f and Figure 7g This is a perspective view showing some cross-sections of the flexible portion 453 according to various embodiments of the present disclosure.

In another embodiment, the cross-sectional shape of the flexible portion 453 can be formed as a circle or an ellipse. For example, when the cross-section of the flexible portion 453 is formed as a circle, an ellipse, or a polygon, the shape of the flexible portion 453 can help alleviate the stress caused by the folding or unfolding operation of the electronic device and reduce the repulsive force caused by bending.

[0109] Figure 9a and Figure 9b This illustrates various embodiments according to the present disclosure. Figure 5 A diagram illustrating various modifications to region C1.

[0110] As described above, the flexible portion 453 of the conductive plate 450 according to various embodiments of the present disclosure may further include rigid reinforcing portions B2 and B3, which are at least partially disposed in other regions and in the upper and / or lower regions. Furthermore, the illustrated rigid reinforcing portions B2 and B3 may be disposed in at least one region of the flexible portion 453 other than region C1.

[0111] refer to Figure 9a The flexible portion 453 of the conductive plate 450 may include a plurality of openings 4531 spaced apart from each other in a first direction (y-axis direction) and / or a second direction (x-axis direction). According to an embodiment, the flexible portion 453 may include a rigid reinforcing portion B2 in the second direction (x-axis direction) where the openings 4531 are omitted. According to one embodiment, the rigid reinforcing portion B2 may not only be present in the display (e.g., Figure 4b The display panel (e.g., the display 400) is securely supported at the rear surface. Figure 4b The display panel 430 can also determine the flexibility of the flexible portion 453. According to one embodiment, rigid reinforcement portions B2 can be arranged in various regions of the flexible portion 453. According to one embodiment, the flexibility of the flexible portion 453 can be determined by the number of rigid reinforcement portions B2 and / or by the spacing distance d7 between the rigid reinforcement portions B2 in the surrounding openings 4531.

[0112] refer to Figure 9bThe flexible portion 453 of the conductive plate 450 may include a plurality of openings 4531 spaced apart from each other in a first direction (y-axis direction) and / or a second direction (x-axis direction). According to an embodiment, the flexible portion 453 may include a rigid reinforcing portion B3 in the second direction (x-axis direction) where the openings 4531 are omitted. According to one embodiment, the rigidity and / or flexibility can be adjusted by adjusting the arrangement density of the openings 4531 arranged in the rigid reinforcing portion B3 to be lower than the arrangement density of the openings 4531 arranged in the surrounding area. According to one embodiment, the flexibility of the flexible portion 453 may be determined by the number of rigid reinforcing portions B3, the arrangement density of the openings 4531, and / or the spacing distance d8 between the openings 4531 around the rigid reinforcing portion B3.

[0113] Figure 10 This is a diagram illustrating the arrangement of flexible openings 4531 in the flexible portion 453 of the conductive plate 450 in each region, taking into account the folding operation of the display 400 according to various embodiments of the present disclosure.

[0114] refer to Figure 10 The bending characteristics of the flexible portion 453 of the conductive plate 450 can be adjusted in each region. According to an embodiment, with the first flat portion 451 and the second flat portion 452 folded to face each other (folded state), the flexible portion 453 can be bent with different radii of curvature in each region, thus allowing for different application of bending characteristics. This is because, in regions where excessive bending is not required, a reduced number of openings 4531 can contribute to increased rigidity. For example, as... Figure 10As shown, with the first flat portion 451 and the second flat portion 452 folded so that they face each other, and advantageously, the flexibility of the first curved region B4 of the flexible portion 453, located furthest from the first flat portion 451 and the second flat portion 452, is determined to be greater than that of the second curved region B5 of the flexible portion 453, located closer to the first flat portion 451 and the second flat portion 452. Therefore, by arranging the arrangement density of the plurality of openings 4531 in the first curved region B4 to be higher than the arrangement density of the plurality of openings 4531 in the second curved region B5, the bending characteristics of the flexible portion 453 in each region can be adjusted. In another embodiment, where relatively less flexibility is required in the second curved region B5, the attachment surface can be increased and rigidity ensured by forming openings 4531 that are thinner and shorter than those in the first curved region B4, or by reducing their arrangement density. In another embodiment, where relatively greater flexibility is required in the first curved region B4, the attachment surface can be reduced by forming openings 4531 that are thicker and longer than those in the second curved region B5, or by increasing their arrangement density. In another embodiment, when the display 400 is in an outward-folding configuration with the first flat portion 451 and the second flat portion 452 folded in opposite directions, the arrangement density of the plurality of openings 4531 in the first curved region B4 can be arranged to be lower than the arrangement density of the plurality of openings 4531 in the second curved region B5. In another embodiment, in addition to adjusting the arrangement density of the plurality of openings 4531, the bending characteristics of the flexible portion 453 in each region can be determined by changing the shape of the plurality of openings 4531, adjusting the spacing of the openings 4531 in the first direction (y-axis direction) and / or the second direction (x-axis direction), and / or partially arranging at least one region in which openings 4531 are omitted. In another embodiment, when a plurality of curvature values ​​are formed in the flexible portion 453, the density of the openings 4531 can be designed to be adjusted according to the curvature values. In particular, flexibility and stiffness can be adjusted by arranging the opening density lower when the curvature value is large and by arranging the opening density higher when the curvature value is small.

[0115] In another embodiment, the flexible display 400 including the foldable conductive plate 450 according to exemplary embodiments of the present disclosure can be applied to foldable electronic devices that operate in an inward and / or outward folding manner within a range of 0º to 360º. In another embodiment, the flexible display 400 including the foldable conductive plate 450 according to exemplary embodiments of the present disclosure can be applied to multiple foldable electronic devices that operate in a multi-folding manner with multiple housings (e.g., three or more housings) configured to fold alternately relative to each other. In another embodiment, the flexible display 400 including the foldable conductive plate 450 according to exemplary embodiments of the present disclosure can also be applied to rollable electronic devices configured to selectively expand the display area by sliding a second housing at least partially from a first housing. For example, the flexible display 400 including the foldable conductive plate 450 according to exemplary embodiments of the present disclosure can be applied to various deformable electronic devices where the shape and / or display area of ​​the display changes accordingly by operatively changing at least one housing.

[0116] According to exemplary embodiments of the present disclosure, the conductive plate can be attached to the polymer layer by an adhesive member. In this case, the conductive plate may further include additional structures to prevent a decrease in flexibility due to adhesion forces on the periphery of the opening or by introducing the adhesive member into the opening.

[0117] Figure 11a This is a cross-sectional view showing the stacked structure of a display 400 according to various embodiments of the present disclosure. Figure 11b This is a partial perspective view of a conductive plate 450 showing a state in which a filling member 460 according to various embodiments of the present disclosure is applied to a flexible portion 453.

[0118] refer to Figure 11a and Figure 11b The display 400 may include a filler member 460 filling a plurality of openings 4531 formed in a flexible portion 453 of a conductive plate 450. According to an embodiment, the flexible portion 453 of the conductive plate 450 may be formed on its front surface as a flat surface relative to the adhesive member P3 by the filler member 460, and on its rear surface as having a flat surface. According to an embodiment, the filler member 460 may include an elastic material that fills the plurality of openings 4531 in the flexible portion 453 of the conductive plate 450 and then cures and / or solidifies. According to an embodiment, the filler member 460 may include resin, polyurethane, silicone, or rubber.

[0119] According to various embodiments, when a conductive plate 450, in which a plurality of openings 4531 are filled by a filling member 460, is attached to a polymer member 440 by an adhesive member P3, deterioration of flexibility and opening visibility due to the adhesive member P3 flowing into the openings 4531 can be prevented.

[0120] Figure 12a This is a cross-sectional view showing the stacked structure of a display 400 according to various embodiments of the present disclosure. Figure 12b This is a partial perspective view showing the state in which the membrane member 470 according to various embodiments of the present disclosure is applied between the conductive plate 450 and the adhesive member P3.

[0121] refer to Figure 12a and Figure 12b The display 400 may include a film member (e.g., thermoplastic polyurethane (TPU)) 470 disposed between the conductive plate 450 and the adhesive member P3. According to an embodiment, the film member 470 may include a flexible portion 453 of the conductive plate 450 and is sized to cover a first flat portion 451 and a second flat portion 452. In another embodiment, the film member 470 may be sized to cover only the flexible portion 453 of the conductive plate 450. According to an embodiment, the film member 470 may be prevented from being observed from the front surface of the display 400 when the adhesive member P3 enters the plurality of openings 4531. In another embodiment, the display 400 may include a printed area disposed between the conductive plate 450 and the adhesive member P3 instead of the film member 470. According to one embodiment, when the film member 470 and / or the printed area are applied only to the flexible portion 453, the adhesive force of the adhesive member P3 on the flexible portion 453 is eliminated or weakened. Therefore, deterioration of the bending characteristics of the flexible portion 453 due to the adhesive force of the adhesive member can be prevented.

[0122] According to various embodiments, although not shown, when viewed from above the display, the adhesive member P3 of the display 400 can be arranged to omit the area overlapping with the flexible portion 453. In another embodiment, when viewed from above the display 400, by differentiating the modulus characteristics of the areas overlapping with the flexible portion 453 and the modulus characteristics of the areas overlapping with the first flat portion 451 and the second flat portion 452, the adhesive member P3 can be prevented from entering the plurality of openings 4531 of the flexible portion 453 in advance. For example, when the adhesive member P3 corresponds to the flexible portion 453, an adhesive member with soft properties can be applied. In the case of such an adhesive member, as the polymer, (meth)acrylate copolymers such as (meth)acrylates or polyurethane acrylates or organosilicon copolymers such as (dimethyl)siloxanes can be used. According to an embodiment, when the adhesive member P3 corresponds to the flexible portion 453, an adhesive member with a modulus of less than 5 × 10⁻⁶ can be applied. 5An adhesive member with a modulus of Pascal (Pa). According to an embodiment, when the adhesive member P3 corresponds to the first flat portion 451 and the second flat portion 452, an adhesive member with rigid properties can be applied. In the case of such an adhesive member P3, a (meth)acrylic acid copolymer such as (meth)acrylate or polyurethane acrylate, or an organosilicon copolymer such as (dimethyl)siloxane, can be used as the polymer. According to an embodiment, when the adhesive member corresponds to the first flat portion 451 and the second flat portion 452, an adhesive member with a modulus of 5 × 10⁻⁶ can be applied. 5 Adhesive components with modulus properties of Pascal (Pa) or greater.

[0123] Figure 13a This is a diagram illustrating a conductive plate 450 according to various embodiments of the present disclosure. Figure 13b This illustrates various embodiments according to the present disclosure. Figure 13a Enlarged view of a portion of regions C6 and C7.

[0124] refer to Figure 13a and Figure 13b The conductive plate 450 may include a surface facing the display (e.g., Figure 4b The first area of ​​the display 400 (e.g., Figure 4b The first flat portion 451 of the first region h1), and the second region facing the display 400 (e.g., Figure 4b The second flat portion 452 of the second region h2), and the third region facing the display 400 (e.g., Figure 4b The flexible portion 453 of the third region h3. According to an embodiment, the flexible portion 453 may include a region in which a plurality of openings 4531 are formed. According to an embodiment, when the first housing structure (e.g., Figure 1 The first shell structure 110) and the second shell structure (e.g., Figure 1 When the second housing structure 120 is in a substantially folded state, the flexible portion 453 may include a bent portion 453a that bends together, a first lower attachment portion 453b connecting the bent portion 453a to the first flat portion 451, and a second lower attachment portion 453c connecting the bent portion 453a to the second flat portion 452. According to one embodiment, the first lower attachment portion 453b and the second lower attachment portion 453c are regions from which a plurality of openings 4531 extend from the bent portion 453a and can be attached to the first housing structure 110 and the second housing structure 120, for example, by an adhesive member. According to one embodiment, stress concentration caused by the bending of the bent portion 453a can be addressed by an attachment structure in which the first lower attachment portion 453b and the second lower attachment portion 453c, with the plurality of openings 4531 extending therefrom, are attached to the housing structures 110 and 120.

[0125] According to various embodiments, the conductive plate 450 may include a first rigid reinforcement region C7 and a second rigid reinforcement region C8 disposed in an upper region and a lower region, where fatigue can accumulate relatively significantly due to frequent folding operations in the flexible portion 453. According to an embodiment, the flexible portion 453 may include a total folded region C6 extending from the first rigid reinforcement region C7 to the second rigid reinforcement region C8.

[0126] According to various embodiments, the flexible portion 453 may include a rigid reinforcement portion 4532, which is formed by omitting at least a portion of a plurality of openings 4531 arranged in the first rigid reinforcement region C7 along the second direction (x-axis direction), creating a gap between one opening 4531a and another adjacent opening 4531b that is larger than the gap between openings 4531 arranged in the total folding region C6. The rigid reinforcement portion 4532 is formed to have a relatively large width t1. According to one embodiment, the rigid reinforcement portion 4532 can be formed by omitting one, two, three, or more openings between one opening 4531a and another adjacent opening 4531b. Although not shown, the second rigid reinforcement region C8 may also have substantially the same construction as the first rigid reinforcement region C7.

[0127] According to various embodiments, the flexible portion 453 can at least partially adjust the curvature in the total folding region C6. According to one embodiment, the curved portion 453a of the flexible portion 453 can at least partially adjust the curvature in the total folding region C6. According to one embodiment, the curvature characteristics of the flexible portion 453 can be adjusted by varying the lengths of the openings 4531 formed in the total folding region C6 in a first direction (y-axis direction). For example, the flexible portion 453 may include a plurality of openings 4531 arranged side-by-side in a first direction (y-axis direction) as follows: a first opening 4531-1 arranged in the first direction (y-axis direction) and having a first length l1 in the total folding area C6; a second opening 4531-2 arranged along the same axis (y-axis) as the first opening 4531-1 and having a second length l2 longer than the first length l1; and a third opening 4531-3 arranged along the same axis (y-axis) as the second opening 4531-2 and having a third length l3 longer than the second length l2. In this case, the openings 4531 may have the same gap in the second direction (x-axis direction) (e.g., Figure 6a The gap d1), has the same gap in the first direction (y-axis direction) (e.g., Figure 6a The gap d2) and the same width itself (e.g., Figure 6a The width w), and only its length is changed (e.g., Figure 6aArranged in a manner that reduces the length l). For example, due to the reduction in the width of the tiny opening 4531 (e.g., Figure 6a The width (w) of the flexible portion 453 may be limited, so it may be advantageous to adjust its bending characteristics by adjusting the length of the flexible portion 453 when the width is relatively constant. According to an embodiment, the opening 4531, which is arranged to gradually increase in length in the first direction (y-axis direction), can be arranged in the same manner in the second direction (x-axis direction). In another embodiment, the length of the opening 4531 can be gradually shortened from the first rigid reinforcement region C7 and the second rigid reinforcement region C8 toward the center of the total folded region C6, or it can be formed to gradually increase its length. In another embodiment, the opening 4531 can be formed such that the length of the opening 4531 gradually decreases or gradually increases from the first rigid reinforcement region C7 toward the second rigid reinforcement region C8. In another embodiment, a plurality of openings 4531 can be arranged to gradually increase or decrease their length in the second direction (x-axis direction) perpendicular to the first direction (y-axis direction). In this case, a plurality of openings 4531 can be arranged to gradually increase their length in the flexible portion 453 in the second direction (x-axis direction) as they travel from the edges near the first flat portion 451 and the second flat portion 452 toward the central portion. This is because a relatively large degree of flexibility is required as the flexible portion 453 travels from the first flat portion and the second flat portion toward the central portion. In other words, this could mean that the bending characteristics of the flexible portion 453 can be adjusted to have relatively high stiffness as it travels from the central portion of the bent portion 453a toward the first lower attachment portion 453b and the second lower attachment portion 453c. In another embodiment, the length of the opening 4531 can be formed to gradually decrease or gradually increase only in at least a partially defined portion of the total folded region C6 in the first direction (y-axis direction) and / or the second direction (x-axis direction). In another embodiment, the length of the opening 4531 can change irregularly rather than gradually.

[0129] Figure 14a The display 130 can at least partially connect with Figure 3 The display 130 is similar to or may include other components of the display.

[0130] refer to Figure 14aThe display 1400 may include a display panel 430 and at least one polymer member 440, a conductive plate 450, and a blocking member 475 (e.g., a polymer layer) sequentially disposed on the display panel 430. The blocking member 475 (e.g., a polymer layer) is arranged to block a flexible portion 453 of the conductive plate 450 having a plurality of openings 4531. According to one embodiment, the blocking member 475 may be formed as a polymer layer and may include at least one of TPU, silicone, rubber, or polyurethane. According to an embodiment, the display 1400 may be arranged to span a first housing structure 110 (e.g., Figure 1 The first surface of the first shell structure 110 (e.g., Figure 1 The first surface 111) and the second shell structure 120 (e.g., Figure 1 The third surface of the second shell structure 120 (e.g., Figure 1 At least a portion of the third surface 121). According to an embodiment, the display 1400 may include a first region h1, a second region h2, and a third region h3, wherein the first region h1 is associated with an electronic device (e.g., Figure 1 The electronic device 100 has a flat region corresponding to the first housing structure 110, a second region h2 is a flat region corresponding to the second housing structure 120, and a third region h3 faces the hinge structure (e.g., Figure 3 (Hinge structure 164). According to an embodiment, the first region h1 and the second region h2 of the display 1400 can be configured to fold or unfold relative to each other based on at least a portion of the third region h3. According to an embodiment, the conductive plate 450 may include a flexible portion 453 corresponding to the third region h3 of the display 1400. According to an embodiment, the flexible portion 453 may include a foldable curved portion 453a and a first lower attachment portion 453b and a second lower attachment portion 453c extending to both sides of the curved portion 453a and respectively connected to the first flat portion 451 and the second flat portion 452.

[0131] According to various embodiments, at least one polymer component 440 may include a buffer layer 441 and a first layer 442 (e.g., a first polymer layer) and a second layer 443 (e.g., a second polymer layer) stacked therebetween with the buffer layer 441. According to one embodiment, at least one polymer component 440 may have a stacked structure for preventing foreign objects from passing through a plurality of openings 4531 formed in the flexible portion 453 of the conductive plate 450 and for preventing visibility of the folding boundary region of the display 1400 due to folding and unfolding operations of the electronic device. According to an embodiment, the buffer layer 441 may be made of a cushioning material (e.g., sponge or foam). According to an embodiment, the first layer 442 (e.g., the first polymer layer) disposed on the buffer layer and the second layer 443 (e.g., the second polymer layer) disposed below the buffer layer 441 may be made of a material for improving surface quality (enhancing visibility) (e.g., TPU). According to an embodiment, the surface roughness of the first layer 442 (e.g., the first polymer layer) and the surface roughness of the second layer 443 (e.g., the second polymer layer) may be the same or different. For example, to improve visibility, the surface roughness of the first layer can be lower than that of the second layer 443 (e.g., the second polymer layer).

[0132] According to various embodiments, the display panel 430, at least one polymer component 440, the conductive plate 450, and the barrier component 475 (e.g., a polymer layer) can be attached to each other via adhesive components 551, 552, 553, and 554. For example, adhesive components 551, 552, 553, and 554 may include at least one of optically clear adhesive (OCA), pressure-sensitive adhesive (PSA), heat-reactive adhesive, common adhesive, or double-sided tape. According to an embodiment, at least one polymer component 440 can be attached to the rear surface of the display panel 430 via a first adhesive component 551. According to an embodiment, the conductive plate 450 can be attached to the rear surface of the polymer component 440 via a second adhesive component 552.

[0133] According to an embodiment, the blocking member 475 (e.g., a polymer layer) can be attached to the rear surface of the conductive plate 450 via a third adhesive member 553. According to an embodiment, the display 1400 can be at least partially attached to the first housing structure 110 and the second housing structure 120 via a fourth adhesive member 554 and a fifth adhesive member 555.

[0134] According to various embodiments, the blocking member 475 (e.g., a polymer layer) can be at least partially attached to the first housing structure 110 and the second housing structure 120 via the fourth adhesive member 554. According to one embodiment, when viewed from above the display, the blocking member 475 (e.g., a polymer layer) attached to the first housing structure 110 and the second housing structure 120 via the fourth adhesive member 554 may include a first lower attachment portion 453b and a second lower attachment portion 453c, but does not include the region overlapping with the curved portion 453a of the flexible portion 453. This can provide a non-adhesive portion for the region of the blocking member 475 (e.g., the polymer layer) corresponding to the curved portion 453a, thereby mitigating stress concentration due to folding operations and separating the first housing structure 110 and the second housing structure 120 from the surface of the display 1400 during the folding operation. In another embodiment, when viewed from above the display 1400, the non-adhesive portion may be arranged to overlap with a region larger than the curved portion 453a and smaller than the flexible portion 453. In another embodiment, when viewed from above the display 1400, the non-adhesive portion may be arranged to overlap with an area larger than the flexible portion 453. 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 an edge region other than the blocking member 475 (e.g., a polymer layer). According to an embodiment, the thickness of the fifth adhesive member 555 may compensate for the thicknesses of the third adhesive member 553, the blocking member 475 (e.g., a polymer layer), and the fourth adhesive member 554. According to one embodiment, the fifth adhesive member 555 may comprise double-sided tape or waterproof tape.

[0135] Figure 14b This 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 disclosure.

[0136] refer to Figure 14bThe conductive plate 450 may include a first flat portion 451 at least partially attached to the first housing structure 110, a second flat portion 452 at least partially attached to the second housing structure 120, and a flexible portion 453 for connecting the first flat portion 451 and the second flat portion 452 and providing bending characteristics at least partially through a plurality of openings 4531. According to an embodiment, the flexible portion 453 may include a curved portion 453a that bends together when the display 1400 is folded, a first lower attachment portion 453b extending from the curved portion 453a to the first flat portion 451, and a second lower attachment portion 453c extending from the curved portion 453a to the second flat portion 452. According to one embodiment, to address stress concentration at the periphery of each flat portion 451 and 452 due 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, respectively. For example, when the flexible portion 453 coincides with the bent portion 453a, stress concentrates at both ends of the bent portion 453a, and the connection portion may be disconnected by the opening 4531 in the corresponding area due to the folding or unfolding operation of the electronic device. Therefore, the stress concentrated in the stress concentration area due to the folding or unfolding operation of the electronic device can be relieved by extending the opening 4531 from the bent portion 453a and at least partially attaching it to the first lower attachment portion 453b and the second lower attachment portion 453c of the first housing structure 110 and the second housing structure 120.

[0137] According to various embodiments, the regions of the first lower attachment portion 453b and the second lower attachment portion 453c may be determined by the endpoint of the last opening 4531 arranged from the curved portion 453a at the left and right ends of the flexible portion 453, a point after the endpoint of the last opening 4531 that includes at least a portion of the first flat portion 451 and the second flat portion 452, or a point that includes a portion of the last opening 4531.

[0138] Figure 15a This is a diagram showing the rear surface of a display 1500 according to various embodiments of the present disclosure. Figure 15b This is a diagram showing the first reinforcing plate 510 and the second reinforcing plate 520 arranged adjacent to each other according to various embodiments of the present disclosure.

[0139] Figure 15a The monitor 1500 can at least partially connect with Figure 3 The display 130 may be similar to or may include other components of the display.

According to one embodiment, the pair of reinforcing plates 510 and 520 may include a first reinforcing plate 510 disposed extending from at least a portion of a first flat portion 451 of the conductive plate 450 to at least a portion of a flexible portion 453, and a second reinforcing plate 520 disposed extending from at least a portion of a second flat portion 451 of the conductive plate 450 to at least a portion of the flexible portion 453. According to one embodiment, the first reinforcing plate 510 and the second reinforcing plate 520 may be formed to avoid the shape of a structure disposed on the rear surface of the conductive plate 450. For example, the first reinforcing plate 510 and the second reinforcing plate 520 may be formed to avoid the shape of an adhesive member P4 disposed along the edge of the rear surface of the conductive plate 450. According to an embodiment, the first reinforcing plate 510 and the second reinforcing plate 520 may be formed to avoid the shape of an adhesive member P4 disposed along the edge of the rear surface of the conductive plate 450. According to an embodiment, the first reinforcing plate 510 and the second reinforcing plate 520 may be formed to avoid the shape of an adhesive member P4 disposed along the edge of the rear surface of the conductive plate 450. Figure 4c The display panel 430 has a folded extension 431, a connecting pad 434, and an FPCB 432, and can be arranged on the rear surface of the conductive plate 450. This prevents an increase in the thickness of the display 1500 due to the stacking of the reinforcing plates 510 and 520.

[0142] According to various embodiments, the first reinforcing plate 510 and the second reinforcing plate 520 may be arranged with different gaps g1, g2, and g3, which are at least partially different from each other based on the axis A in the flexible portion of the conductive plate 450. When the display 1500 is folded based on the flexible portion 453, these gaps g1, g2, and g3 allow the first reinforcing plate 510 and the second reinforcing plate 520 to fold together with the first flat portion 451 and the second flat portion 452 of the conductive plate 450.

[0143] According to various embodiments, the first reinforcing plate 510 and the second reinforcing plate 520 may be arranged facing each other over substantially most of the area with a first gap g1. According to an embodiment, the first reinforcing plate 510 may include a first extension 511 and a second extension 512 for covering the upper end region (region C8) and lower end region (region C9) of the flexible portion 453 of the conductive plate 450. According to an embodiment, the second reinforcing plate 520 may include a third extension 521 and a fourth extension 522 for covering the upper end region C8 and lower end region C9 of the flexible portion 453 of the conductive plate 450. According to an 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 an 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 an 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 of the areas facing each other. The region with a larger gap g3 can assist electrical connection members (e.g., FPCBs) extending from the first internal space of the first housing structure 110 of the electronic device to the second internal space of the second housing structure 120 via a hinge structure. Figure 3 The arrangement space of at least one wiring member 163. According to an embodiment, in order to form the first gap g1, the second gap g2 and / or the third gap g3, the first reinforcing plate 510 and the second reinforcing plate 520 may be formed as having protrusions that at least partially protrude from the edge of the region or including recessed notches. According to one embodiment, the first reinforcing plate 510 and the second reinforcing plate 520 may be made of SUS or Al. In another embodiment, the first reinforcing plate 510, the second reinforcing plate 520 and / or the conductive plate 450 may be made of high-strength non-magnetic SUS to prevent magnetization caused by at least one magnet of the detected member arranged inside the electronic device and used as a detection sensor (e.g., a Hall sensor).

[0144] According to various embodiments, the display 1500 may further include at least one additional adhesive member 540, which is longitudinally arranged on the rear surfaces of the first reinforcing plate 510 and the second reinforcing plate 520 around the regions of the gaps g1, g2, and g3 facing each other. According to one embodiment, the additional adhesive member 540 can prevent bending deformation of the first reinforcing plate 510 and the second reinforcing plate 520 in the portions of the gaps g1, g2, and g3 due to folding operations, or deformation and lifting due to drop impacts.

[0146] According to various embodiments, the first reinforcing plate 510 and the second reinforcing plate 520 may each include attachment regions PA1 and PA2 that are at least partially attached to the rear surface of the conductive plate 450 by an adhesive member.

[0147] refer to Figure 16a The first reinforcing plate 510 can be attached to at least a portion of the first attachment region PA1 of the conductive plate 450 via an adhesive member. According to one embodiment, the first attachment region PA1 may include at least a portion extending from at least a portion of the first flat portion 451 of the conductive plate 450 to at least a portion of the flexible portion 453 (e.g., Figure 13b The area of ​​the first lower attachment portion 453b). According to an embodiment, the second reinforcing plate 520 can be attached to at least a portion of the second attachment region PA2 of the conductive plate 450 by an adhesive member. According to one embodiment, the second attachment region PA2 may include at least a portion extending from at least a portion of the second flat portion 452 of the conductive plate 450 to at least a portion of the flexible portion 453 (e.g., Figure 13b The area of ​​the second lower attachment portion 453c).

[0148] refer to Figure 16b The first attachment region PA1, to which the first reinforcing plate 510 is attached, may include a region corresponding to at least a portion of the first flat portion 451 of the conductive plate 450, excluding the flexible portion 453. According to an embodiment, the second attachment region PA2, to which the second reinforcing plate 520 is attached, may include a region corresponding to at least a portion of the second flat portion 452 of the conductive plate 450, excluding the flexible portion 453.
