Description

Electronic device including foldable conductive plate

Technical Field

Various embodiments of the present disclosure relate to electronic devices that include a foldable conductive plate.

Background

As the functional gap between each manufacturer is greatly reduced, electronic devices are becoming increasingly thinner to meet the consumer's purchase needs. Improvements are being made to electronic devices in order to increase their rigidity, enhance their design aspects, and differentiate their functional elements. Such electronic devices are gradually changing from a uniform rectangular shape to various shapes. For example, the electronic device may be conveniently carried and have a deformable structure that may use a large screen display when in use. Foldable electronic devices have been continuously released and support structures for foldable displays may also be improved.

Disclosure of Invention

Technical problem

The foldable electronic device may include a hinge structure and a first case structure and a second case structure connected in opposite directions to each other in the hinge structure. When the first housing structure is rotated in a range of 0 ° to 360 ° with respect to the second housing structure by the hinge structure, the foldable electronic device may be operated in an inwardly folded and/or outwardly folded manner. The foldable electronic device may comprise a flexible display arranged to span the first and second housing structures in an unfolded state of 180 °.

Generally, an electronic device (e.g., a bar type electronic device) having a single case may include at least one conductive plate disposed at a rear surface of a display in an inner space and may help to reinforce rigidity by supporting the display and to shield noise. Such a conductive plate may be grounded to the ground of the printed circuit board disposed inside the electronic device through the electrical connection member.

The foldable electronic device may have a configuration in which the first housing structure and the second housing structure are moved relative to each other and separated from each other by the hinge structure. Thus, in case the conductive plates cannot be folded, two conductive plates may be arranged separately in each housing structure.

However, such a separately arranged structure of the conductive plates causes folding marks in a corresponding portion of the display near a corner portion of each conductive plate of the hinge structure by frequent folding operations of the electronic device, and these folding marks may cause malfunction of the electronic device and reduce operational reliability.

Various embodiments of the present disclosure may provide an electronic device including a foldable conductive plate.

Various embodiments of the present disclosure may provide an electronic device including a foldable conductive plate capable of adjusting flexibility in each region according to folding characteristics.

Various embodiments of the present disclosure may provide an electronic device including a foldable conductive plate having low production costs and excellent assembly properties.

Detailed Description

Fig. 1 is a view illustrating an electronic apparatus in a flat state according to an embodiment of the present disclosure. Fig. 2 is a view illustrating an electronic apparatus in a folded state according to an embodiment of the present disclosure.

Referring to fig. 1, an electronic device 100 may include a pair of

case structures

110 and 120 rotatably coupled to be folded with respect to each other via a hinge structure (e.g., a hinge structure 164 in fig. 3), a hinge cover 165 covering a foldable portion of the pair of

case structures

110 and 120, and a display 130 (e.g., a flexible display or a foldable display) disposed in a space formed by the pair of

case structures

110 and 120. In the description, a surface on which the display 130 is disposed may be referred to as a front surface of the electronic apparatus 100, and an opposite side of the front surface may be referred to as a rear surface of the electronic apparatus 100. A surface surrounding a space between the front surface and the rear surface may be referred to as a side surface of the electronic apparatus 100.

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 back cover 140, and a second back cover 150, the first housing structure 110 including a sensor region 131 d. The pair of

housing structures

110 and 120 of the electronic device 100 is not limited to the shapes or combinations shown in fig. 1 and 2, but may be implemented in various shapes or combinations. For example, in another embodiment, the first housing structure 110 and the first rear cover 140 may be formed as a unitary body, and the second housing structure 120 and the second rear cover 150 may be formed as a unitary body.

In one embodiment, the first and

second housing structures

110 and 120 may be disposed on both sides with respect to 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 state or a 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 symmetrical shape to the second housing structure 120 in other regions. In another embodiment, the sensor region 131d may be disposed in a specific region of the second housing structure 220 or may be replaced.

In one embodiment, the first case structure 110 may be connected to a hinge structure (e.g., the hinge structure 164 in fig. 3) during a flat state of the electronic device 100, and may include a first surface 111 facing a front surface of the electronic device 100, a second surface 112 facing away from the first surface 111, and a first side member 113 enclosing at least a portion of a 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.

In one embodiment, the second case structure 120 may be connected to a hinge structure (e.g., the hinge structure 164 in fig. 3) during a flat state of the electronic device 100, and may include a third surface 121 facing a front surface of the electronic device 100, a fourth surface 122 facing away from the third surface 121, and a second side member 123 enclosing at least a portion of a 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.

In one embodiment, the electronic device 100 may include a recess 101, the recess 101 being formed to accommodate the display 130 by a structural combination of the shapes of the first housing structure 110 and the second housing structure 120. The recess 101 may be substantially the same size as the display 130. In one embodiment, the recess 101 may have two or more different widths in a direction perpendicular to the folding axis (a) due to the sensor region 131 d. For example, the recess 101 may have a first width (W1) between a first portion 120a of the second case structure 120 parallel to the folding axis (a) and a first portion 110a of the first case structure 110 formed at an edge of the sensor region 131d, and a second width (W2) between a second portion 120b of the second case structure 120 and a second portion 110b of the first case 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 may be formed to have a first width (W1) (asymmetric shape) from the first portion 110a of the first case structure 110 to the first portion 120a of the second case structure 120, and a second width (W2) (symmetric shape) from the second portion 110b of the first case structure 110 to the second portion 120b of the second case structure 120. In one embodiment, the first portion 110a and the second portion 110b of the first housing structure 110 may be located at different distances from the fold axis (a). The width of the recess is not limited to the examples shown above. In various embodiments, the recess 101 may have two or more different widths due to the shape of the sensor region 131d or the asymmetry of the first housing structure 110 or the second housing structure 120.

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.

In one embodiment, the sensor region 131d may be formed to have a predetermined region near one corner of the first case structure 110. However, the arrangement, shape, or size of the sensor region 131d is not limited to the illustrated example. For example, in certain embodiments, the sensor region 131d may be formed at another corner of the first housing structure 110, or in any region between the upper and lower corners. In another embodiment, the sensor region 131d may be disposed at a portion of the second housing structure 120. In another embodiment, the 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, the electronic device 100 may include a member exposed to a front surface of the electronic device 100 through the sensor region 131d or through one or more openings disposed in the sensor region 131 d. These components may include, for example, at least one of a front camera, a receiver, a proximity sensor, an illuminance sensor, an iris recognition sensor, an ultrasonic sensor, or an indicator.

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 back cover 150 may be disposed on the fourth surface 122 of the second housing structure 120, and at least a portion of the periphery thereof may be wrapped by the second housing structure 120.

In the illustrated embodiment, the first and second rear covers 140 and 150 may have a substantially symmetrical shape with respect to the folding axis (a). In another embodiment, the first and second rear covers 140 and 150 may have various different shapes. In another embodiment, the first rear cover 140 may be formed as a unitary body with the first housing structure 110 and the second rear cover 150 may be formed as a unitary body with the second housing structure 120.

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 a space in which various components of the electronic device 100 (e.g., a printed circuit board, an antenna module, a sensor module, and a battery) may be arranged. In one embodiment, one or more components may be disposed on a rear surface of the electronic device 100 or visually exposed via the rear surface 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. The sensors may include a proximity sensor, a rear camera, and/or a flash. In another embodiment, at least a portion of the sub-display 152 may be visually exposed through the second rear area 151 of the second rear cover 150.

The electronic device 100 may be disposed on a space formed by the pair of

housing structures

110 and 120. For example, the electronic device 100 may be disposed in a recess (e.g., recess 101 in fig. 1) formed by the pair of

housing structures

110 and 120, and may be arranged to occupy substantially a majority of a front surface of the electronic device 100. Accordingly, the front surface of the electronic device 100 may include the display 130, a portion (e.g., an edge region) of the first housing structure 110 near the display 130, and a portion (e.g., an edge region) of the second housing structure 120 near the display 130. In one embodiment, the back surface of electronic device 100 may include first back cover 140, a portion (e.g., an edge region) of first housing structure 110 proximate first back cover 140, second back cover 150, and a portion (e.g., an edge region) of second housing structure 120 proximate second back cover 150.

In one embodiment, display 130 may refer to a display at least a portion of which may 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 at one side (e.g., a right side of the folding area 131 c) with respect to the folding area 131c, and a second area 131b disposed at the other side (e.g., a left side of the folding area 131 c). For example, the first region 131a may be disposed on the first surface 111 of the first case structure 110, and the second region 131b may be disposed on the third surface 121 of the second case structure 120. This division of the display 130 is merely an example, and the display 130 may be subdivided into a plurality of regions (e.g., four or more regions) according to structure or function. For example, in the embodiment of fig. 1, the region of display 130 may be subdivided relative to fold region 131c or a fold axis (a) extending parallel to the y-axis. However, in another embodiment, the area of display 130 may be subdivided relative to a different fold region (e.g., a fold region parallel to the x-axis) or a different fold axis (e.g., a fold axis parallel to the x-axis). The foregoing subdivision of the display is based solely on the physical division of the pair of

housing structures

110 and 120 and the hinge structure (e.g., hinge structure 164 in fig. 3), and the display 130 may appear substantially full screen through the pair of

housing structures

110 and 120 and the hinge structure (e.g., hinge structure 164 in fig. 3). In one embodiment, the first and

second regions

131a and 131b may have a symmetrical shape with respect to the folding region 131 c. Although the first region 131a may include a notch region (e.g., the notch region 133 in fig. 3) cut according to the presence of the sensor region 131d, the first region 131a may have a shape symmetrical to the second region 131b in other portions. In other words, the first and

second regions

131a and 131b may include portions having a symmetrical shape and portions having an asymmetrical shape.

Referring to fig. 2, a hinge cover 165 may be disposed between the first housing structure 110 and the second housing structure 120 to cover the internal components (e.g., the hinge structure 164 in fig. 3). In one embodiment, the hinge cover 165 may be covered by portions of the first and

second case structures

110 and 120 or exposed to the outside according to an operation state (e.g., a flat state or a folded state) of the electronic device 100.

For example, when the electronic device 100 is in a flat state as shown in fig. 1, the hinge cover 165 may be covered by the first and

second housing structures

110 and 120 so as not to be exposed. When the electronic device 100 is in a folded state (e.g., a fully folded state) as shown in fig. 2, the hinge cover 165 may be exposed to the outside between the first case structure 110 and the second case structure 120. When the electronic device 100 is in an intermediate state where the first case structure 110 and the second case structure 120 form an angle, the hinge cover 165 may be partially exposed to the outside between the first case structure 110 and the second case 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.

Next, a description is given of the configuration of the first and

second case structures

110 and 120 and the area of the display 130 according to the operation state (e.g., the flat state or the folded state) of the electronic apparatus 100.

In one embodiment, when the electronic device 100 is in a flat state (e.g., the state of fig. 1), the first and

second housing structures

110 and 120 may form an angle of 180 degrees, and the first and

second regions

131a and 131b of the display may be arranged to face the same direction. In addition, the folding region 131c may be coplanar with the first and

second regions

131a and 131 b.

In one embodiment, the first housing structure 110 and the second housing structure 120 may be arranged to face each other when the electronic device 100 is in a folded state (e.g., the state of fig. 2). The first and

second regions

131a and 131b of the display 130 may face each other to form a narrow angle (e.g., between 0 and 10 degrees). At least a portion of the folding region 131c may form a curved surface having a preset curvature.

In one embodiment, the first housing structure 110 and the second housing structure 120 may be arranged to form an angle when the electronic device 100 is in the intermediate state. The first and

second regions

131a and 131b of the display 130 may form an angle greater than that of the folded state and smaller than that of the flat state. At least a portion of the folding region 131c may form a curved surface having a preset curvature. The curvature may be smaller than the curvature of the folded state.

Fig. 3 is an exploded perspective view of an electronic device according to an embodiment of the present disclosure.

Referring to fig. 3, in one embodiment, 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 back cover 140, and a second back cover 150. In the description, the display 130 may be referred to as a display unit, a display module, or a display assembly.

Display 130 may include a display panel 131 (e.g., a flexible display panel), and at least one panel 132 or layer on which display panel 131 is located. In one embodiment, the 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 substantially the same area as that of the display, and a region facing the folding region of the display may be formed to be bendable. The plate 132 may include at least one auxiliary material layer (e.g., a graphite member) disposed at the rear 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 partial region of the first plate 132 may be formed in a shape corresponding to the cut region 133 of the display panel 131.

The support member assembly 160 may include: the 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)) crossing the first and

second support members

161 and 162.

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

In one embodiment, at least a portion of the hinge structure 164 and the routing member 163 may be disposed within the support member assembly 160. The wiring member 163 may be arranged in a direction (e.g., x-axis direction) intersecting the first and

Hereinafter, the configuration of the conductive plate 450 will be described in detail.

Fig. 5 is a diagram illustrating a conductive plate 450 according to various embodiments of the present disclosure.

Referring to fig. 5, the conductive plate 450 may include a first flat portion 451 facing a first region (e.g., the first region h1 of fig. 4 b) of a display (e.g., the display 400 of fig. 4 b), a second flat portion 452 facing a second region (e.g., the second region h2 of fig. 4 b) of the display 400, and a flexible portion 453 facing a third region h3 (e.g., the third region h3 of fig. 4 b) of the display 400. According to an embodiment, the conductive plate 450 may include light-

weight regions

4511 and 4521 arranged in at least some regions of the first and second

Fig. 6a to 6e are enlarged views illustrating respective portions of fig. 5.

Fig. 6a is an enlarged view illustrating the region C1 of fig. 5 according to various embodiments of the present disclosure, and although fig. 6a is an enlarged view of a partial region (e.g., the region C1) of the flexible portion 453 of the conductive plate 450, the partial region may be formed in substantially the entire region of the flexible portion 453.

Referring to fig. 6a, the flexible portion 453 may include a pattern. According to one embodiment, the pattern may include a plurality of openings 4531 spaced apart from one another. In some embodiments, the plurality of openings 4531 may be replaced with a plurality of notches. According to an embodiment, the plurality of openings 4531 may be formed as oblong holes in the first direction (e.g., y-axis direction) of the flexible portion 453. According to an exemplary embodiment, the plurality of openings 4531 may be alternately arranged to coincide with each other in the second direction (e.g., x-axis direction) of the flexible portion 453. According to an embodiment, the plurality of openings 4531 may be arranged at regular or irregular intervals in the first direction (e.g., the y-axis direction) and/or the second direction (e.g., the x-axis direction). According to an embodiment, the plurality of openings 4531 may be formed in the same shape or different shapes. According to an embodiment, the flexible portion 453 may exhibit elastic force to be restored to an original state after being deformed by punching a mesh structure (a mesh structure, a slit structure, or an opening structure) using the plurality of openings 4531, and such elastic force may help to provide flexibility of the flexible portion.

According to various embodiments, the flexibility of the flexible portion 453 may be determined by a gap, a shape, or an arrangement density between the plurality of openings 4531. For example, the flexibility of the flexible portion 453 can be determined by the length l of the cell opening. According to an embodiment, the flexibility of the flexible portion 453 may be determined by the width w of the cell opening. According to an embodiment, the flexibility of the flexible portion 453 may be determined by a first gap d1 between the openings 4531 formed in the second direction (e.g., the x-axis direction). According to an embodiment, the flexibility of the flexible portion 453 may be determined by the second gap d2 between the openings 4531 formed in the first direction (e.g., the y-axis direction). As will be described later, the flexibility of the flexible portion 453 can be determined by the arrangement density between the plurality of openings 4531 arranged in the first direction (e.g., the y-axis direction) and/or the second direction (e.g., the x-axis direction).

Fig. 6d is an enlarged view illustrating region C4 of fig. 5, according to various embodiments of the present disclosure. To lighten the electronic device, the conductive plate may include a lightening region 4511 formed in at least a part of the region. According to an embodiment, the lightweight region 4511 may include a plurality of holes 4512, and the plurality of holes 4512 may be formed in a first flat portion (e.g., the first flat portion 451 of fig. 5) and/or a second flat portion (e.g., the second flat portion 452 of fig. 5) and spaced apart from each other at a predetermined interval. According to one embodiment, the plurality of holes 4512 may be formed in a circular shape. In another embodiment, the plurality of holes 4512 may be formed in various shapes other than a circle, such as an oval, a square, or a polygon. In another embodiment, the lightweight region 4511 (or the lightweight region 4521) may include a plurality of notches formed at a predetermined depth, and the conductive plate is perforated in the notches. In this case, the light weight of the conductive plate may be determined according to the shape, depth, or size of the notch. According to one embodiment, the size or shape of the lightweight region 4511 may be determined without impairing the original functions such as the rigidity enhancement function, the heat radiation function, and/or the noise shielding function of the conductive plate 450.

Fig. 6e is an enlarged view illustrating the region C5 of fig. 5, the conductive plate 450 may include a support 4502 protruding along an edge of the flexible part 453 in a length including at least the flexible part 453 so as to support a lower end portion in a third region (e.g., the third region h3 of fig. 4 b) of a display (e.g., the display 400 of fig. 4 b), according to various embodiments of the present disclosure. In another embodiment, the conductive plate 450 may include a support (e.g., the support 4501 of fig. 5) formed in the same manner so as to support an upper end of the third region (e.g., the third region h3 of fig. 4 b) of the display (e.g., the display 400 of fig. 4 b). According to an embodiment, the

supports

4501 and 4502 may be formed to protrude further than edges of the upper and lower ends of the display panel 430 in the flexible portion 453 when viewed from above the display (e.g., the display 400 of fig. 4 b). In another embodiment, the support 4502 may be the same as the display panel 430. According to one embodiment, supports 4501 and 4502 include a flexible portion 453 and may extend to at least a portion of first planar portion 451 and/or at least a portion of second planar portion 452. In another embodiment, supports 4501 and 4502 may extend to an entire edge of first flat portion 451 and/or an entire edge of second flat portion 452.

Fig. 7 a-7 e are diagrams illustrating various modifications of region C2 of fig. 5, according to various embodiments of the present disclosure. In fig. 7a to 7e, although a modified arrangement structure for rigidly reinforcing the opening 4531 of the upper end portion of the conductive plate 450 is shown and described, the rigid reinforcing structure of the lower end portion of the conductive plate 450 may have substantially the same structure.

Referring to fig. 7a, for the upper end of the rigid reinforced conductive plate 450, the upper end region of the flexible portion 453 may include a rigid reinforced portion (portion B1) formed such that there is no modified opening 4534 removed through some of the openings 4531 or an opening formed by omitting all of the openings 4531 in the second direction (e.g., the x-axis direction).

Referring to fig. 7b, with respect to the upper end portion of the rigid reinforcing conductive plate 450, by alternately omitting one opening 4531 arrangement in the second direction (e.g., x-axis direction) of the flexible portion 453, the upper end region of the flexible portion 453 may be formed to have a third interval d3 wider than the outer periphery.

Referring to fig. 7c, for the upper end portion of the rigid reinforcing conductive plate 450, the upper end region of the flexible portion 453 may be formed to have a fourth interval d4 wider than the outer periphery by modifying an opening 4534 from which a portion of the opening 4531 is removed or by alternately omitting two openings 4531 arrangements in the second direction (e.g., x-axis direction) of the flexible portion 453.

Referring to fig. 7d, for the upper end portion of the rigid reinforcing conductive plate 450, the upper end region of the flexible portion 453 may be formed to have a fifth interval d5 wider than the outer periphery by modifying an opening 4534 from which a portion of the opening 4531 is removed or by alternately omitting the arrangement of three openings 4531 in the first direction (e.g., x-axis direction) of the flexible portion 453.

Referring to fig. 7e, for the upper end portion of the rigid reinforcing conductive plate 450, the upper end region of the flexible portion 453 may be formed to have a sixth interval d6 wider than the outer periphery by modifying the opening 4534 with a portion of the opening 4531 removed or by alternately omitting the arrangement of four openings 4531 in the first direction (e.g., x-axis direction) of the flexible portion 453.

Fig. 7f and 7g are perspective views illustrating some cross-sections of the flexible portion 453, according to various embodiments of the present disclosure.

Referring to fig. 7f and 7g, the flexible portion 453 of the conductive plate 450 may be formed in a mesh structure through a plurality of openings 4531. In this case, the cross-sectional shape of the flexible portion 453 formed through the opening 4531 may be formed in a square shape or a polygonal shape (e.g., an octagon shape). In another embodiment, the cross-sectional shape of the flexible portion 453 may be formed in a circular or elliptical shape. For example, when the cross section of the flexible portion 453 is formed in a circular shape, an elliptical shape, or a polygonal shape, the shape of the flexible portion 453 may help to alleviate stress caused by a folding or unfolding operation of the electronic device and reduce repulsive force due to bending.

Fig. 8a to 8c are diagrams illustrating various shapes of

openings

4535, 4536, and 4537 according to various embodiments of the present disclosure.

As shown in fig. 8a to 8c, in addition to the oval-shaped opening (e.g., the opening 4531 of fig. 6 a) extending in the first direction (y-axis direction) as described above, it is contemplated that the flexible portion 453 of the conductive plate 450 may be replaced with

openings

4535, 4536, and 4537 of various shapes for the perforation. For example, the

openings

4535, 4536, and 4537 may include circular openings 4535, rectangular openings 4536, and/or diamond-shaped openings 4537 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 shapes of openings may be formed. In other embodiments, the openings may be arranged to have at least partially different shapes.

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

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 in the first direction (y-axis direction) and/or the second direction (x-axis direction). According to an embodiment, the flexible portion 453 may include the rigid reinforcement portion B2 omitting the opening 4531 in the second direction (x-axis direction). According to one embodiment, rigid reinforcement portion B2 may not only securely support a display panel (e.g., display panel 430 of fig. 4B) at the back surface of a display (e.g., display 400 of fig. 4B) but may also determine the flexibility of flexible portion 453. According to one embodiment, the rigid reinforcement portion B2 may be disposed 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 rigid reinforcement portions B2 and/or the separation distance d7 between the surrounding openings 4531 through the rigid reinforcement portion B2.

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 in the first direction (y-axis direction) and/or the second direction (x-axis direction). According to an embodiment, the flexible portion 453 may include the rigid reinforcement portion B3 omitting the opening 4531 in the second direction (x-axis direction). According to one embodiment, the rigidity reinforcement and/or flexibility can be adjusted by adjusting the arrangement density of the openings 4531 arranged in the rigidity reinforcement 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 reinforcement portions B3, the arrangement density of the openings 4531, and/or the spacing distance d8 between the openings 4531 around the rigid reinforcement portion B3.

Fig. 10 is a diagram illustrating an arrangement configuration of the openings 4531 in consideration of the flexibility of the flexible portion 453 of the conductive plate 450 in each region according to the folding operation of the display 400 according to various embodiments of the present disclosure.

Referring to fig. 10, the bending characteristics of the flexible portion 453 of the conductive plate 450 may be adjusted in each region. According to an embodiment, in a state where the first and second

flat portions

451 and 452 are folded to face each other (folded state), the flexible portion 453 may be bent at a different radius of curvature in each region, and thus the bending characteristics may be differently applied. This is because, in the region where excessive bendability is not required, the reduced number of openings 4531 may contribute to reinforcement of rigidity. For example, as shown in fig. 10, in a state where the first flat portion 451 and the second flat portion 452 are folded to face each other, and it is advantageous that the flexibility of the first bending region B4 of the flexible portion 453 located farthest from the first flat portion 451 and the second flat portion 452 is determined to be greater than the flexibility of the second bending region B5 of the flexible portion 453 located near 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 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 portion 453 in each region can be adjusted. In another embodiment, in the case where the second bending region B5 requires relatively less flexibility, by forming the openings 4531 thinner and shorter than those in the first bending region B4 or by reducing the arrangement density thereof, it is possible to increase the attachment surface and ensure rigidity. In another embodiment, in the case where a relatively greater flexibility is required for the first bending region B4, the attachment surface may be reduced by forming the openings 4531 thicker and longer than those in the second bending region B5 or by increasing the arrangement density thereof. In another embodiment, when the display 400 is in an outwardly folded form in which the first and second

flat portions

451 and 452 are reversely folded, the arrangement density of the plurality of openings 4531 in the first curved region B4 may 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 may be determined by changing the shape of the plurality of openings 4531, adjusting the interval 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 the openings 4531 are omitted. In another embodiment, when a plurality of curvature values are formed in flexible portion 453, it may be designed to adjust the density of openings 4531 according to the curvature values. In particular, the flexibility and stiffness can be adjusted by arranging the density of the openings to be lower when the curvature value is larger and by arranging the density of the openings to be larger when the curvature value is smaller.

In another embodiment, the flexible display 400 including the foldable conductive plate 450 according to an exemplary embodiment of the present disclosure may be applied to a foldable electronic device operating in an inward folding and/or outward folding manner in a range of 0 ° to 360 °. In another embodiment, the flexible display 400 including the foldable conductive plates 450 according to an exemplary embodiment of the present disclosure may be applied to a multi-foldable electronic device operating in a multi-folding manner in which a plurality of housings (e.g., three or more housings) are configured to be alternately folded with respect to each other. In another embodiment, the flexible display 400 including the foldable conductive plate 450 according to an exemplary embodiment of the present disclosure may also be applied to a rollable electronic device configured to selectively expand a display area by sliding the second housing at least partially from the first housing. For example, the flexible display 400 including the foldable conductive plate 450 according to an exemplary embodiment of the present disclosure may be applied to various deformable electronic devices in which the shape and/or display area of the display is changed accordingly by operatively changing at least one housing.

According to an exemplary embodiment of the present disclosure, the conductive plate may be attached to the polymer layer by an adhesive member. In this case, the conductive plate may further include an additional structure for preventing a decrease in flexibility due to adhesion of a peripheral region of the opening or introduction of the adhesive member into the opening.

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

Referring to fig. 11a and 11b, the display 400 may include a filling member 460 filled in a plurality of openings 4531 formed in the flexible portion 453 of the conductive plate 450. According to an embodiment, the flexible portion 453 of the conductive plate 450 may be formed to have a flat surface at a front surface thereof with respect to the adhesive member P3 through the filling member 460 and to have a flat surface at a rear surface thereof. According to an embodiment, the filling member 460 may include an elastic material filled in the plurality of openings 4531 of the flexible portion 453 of the conductive plate 450 and then cured and/or solidified. According to an embodiment, the filling member 460 may include resin, polyurethane, silicone, or rubber.

According to various embodiments, when the conductive plate 450 in which the plurality of openings 4531 are filled by the filling member 460 is attached to the polymer member 440 by the adhesive member P3, it is possible to prevent deterioration of flexibility and opening visibility due to the adhesive member P3 flowing into the openings 4531.

Fig. 12a is a cross-sectional view illustrating a stacked structure of a display 400 according to various embodiments of the present disclosure. Fig. 12b is a partial perspective view illustrating a state in which the film member 470 according to various embodiments of the present disclosure is applied between the conductive plate 450 and the adhesive member P3.

Referring to fig. 12a and 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 the flexible portion 453 of the conductive plate 450 and be formed to cover the size of the first and second

flat portions

451 and 452. In another embodiment, the membrane member 470 may be formed in a size that may cover only the flexible portion 453 of the conductive plate 450. According to an embodiment, when the adhesive member P3 enters the plurality of openings 4531, the film member 470 may be prevented from being viewed from the front surface of the display 400. In another embodiment, the display 400 may include a printed region 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 region are applied only to the flexible portion 453, the adhesive force of the adhesive member P3 to the flexible portion 453 is removed or weakened. Accordingly, it is possible to prevent the bending characteristics of the flexible portion 453 from being deteriorated due to the adhesive force of the adhesive member.

According to various embodiments, although not shown, the adhesive member P3 of the display 400 may be arranged to omit an area overlapping the flexible portion 453 when viewed from above the display. In another embodiment, by differently arranging the modulus property of the region overlapping with the flexible portion 453 and the modulus property of the region overlapping with the first and second

flat portions

451 and 452 when viewed from above the display 400, the adhesive members P3 may be prevented from entering the plurality of openings 4531 of the flexible portion 453 in advance. For example, in the case where the adhesive member P3 corresponds to the flexible portion 453, an adhesive member having a soft type property may be applied. In the case of such an adhesive member, as the polymer, a (meth) acrylic copolymer such as (meth) acrylate or urethane acrylate, or a silicone copolymer such as (dimethyl) siloxane may be used. According to an embodiment, in the case that the adhesive member P3 corresponds to the flexible portion 453, a tape having less than 5 × 10 may be applied⁵An adhesive member having a modulus characteristic of pascal (Pa). According to the embodiment, the adhesive member P3 correspond to the first and second

flat portions

451 and 452, an adhesive member having a hard type property may be applied. In the case of such an adhesive member P3, a (meth) acrylic acid copolymer such as (meth) acrylate or urethane acrylate or a silicone copolymer such as (dimethyl) siloxane or the like as a polymer may be used. According to the embodiment, in the case that the adhesive member corresponds to the first and second

flat portions

451 and 452, the adhesive member having a size of 5 × 10 may be applied⁵An adhesive member of modulus characteristics of pascal (Pa) or greater.

Fig. 13a is a diagram illustrating a conductive plate 450 according to various embodiments of the present disclosure. Fig. 13b is an enlarged view illustrating a portion of region C6 and region C7 of fig. 13a, according to various embodiments of the present disclosure.

Referring to fig. 13a and 13b, the conductive plate 450 may include a first flat portion 451 facing a first region (e.g., the first region h1 of fig. 4 b) of the display (e.g., the display 400 of fig. 4 b), a second flat portion 452 facing a second region (e.g., the second region h2 of fig. 4 b) of the display 400, and a flexible portion 453 facing a third region (e.g., the third region h3 of fig. 4 b) of the display 400. 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., 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 the substantially folded state, the flexible portion 453 may include a curved portion 453a that curves together, a first lower attachment portion 453b connected from the curved portion 453a to the first flat portion 451, and a second lower attachment portion 453c connected from the curved portion 453a to the second flat portion 452. According to one embodiment, the first and second

lower attachment portions

453b and 453c are regions where the plurality of openings 4531 extend from the bent portion 453a and may be attached to the first and

second case structures

110 and 120, for example, by adhesive members. According to one embodiment, a stress concentration phenomenon due to bending of the bending portion 453a may be solved by the first and second

lower attachment portions

453b and 453c, in which the plurality of openings 4531 extend, being attached to the attachment structure of the

case structures

110 and 120.

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

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

According to various embodiments, the flexible portion 453 may at least partially adjust the flexibility in the total folding area C6. According to one embodiment, the bending portion 453a of the flexible portion 453 may at least partially adjust the flexibility in the total folding area C6. According to one embodiment, by differently forming the length of the opening 4531 arranged in the first direction (y-axis direction) in the total folding area C6, the bending characteristic of the flexible portion 453 may be adjusted. For example, the flexible portion 453 may include a plurality of openings 4531, the plurality of openings 4531 being arranged side by side in the first direction (y-axis direction) in the following manner: a first opening 4531-1 arranged in the first direction (y-axis direction) and having a first length l1 in the total fold region C6, a second opening 4531-2 arranged along the same axis (y-axis) as the axis (y-axis) of the first opening 4531-1 and having a second length l2 longer than the first length l1, a third opening 4531-3 arranged along the same axis (y-axis) as the axis (y-axis) of the second opening 4531-2 and having a third length l3 longer than the second length l 2. In this case, the openings 4531 may have the same gap (e.g., the gap d1 of fig. 6 a) in the second direction (x-axis direction), the same gap (e.g., the gap d2 of fig. 6 a) and the same width itself (e.g., the width w of fig. 6 a) in the first direction (y-axis direction), and be arranged in such a manner that only the length thereof (e.g., the length l of fig. 6 a) is changed. For example, since there may be a limit to reducing the size of the width (e.g., width w of fig. 6 a) of the minute opening 4531, it may be advantageous to adjust the bending characteristics of the flexible portion 453 by adjusting the length thereof when the widths are relatively the same. According to an embodiment, the openings 4531 arranged in a manner of being gradually longer in the first direction (y-axis direction) may be arranged in the second direction (x-axis direction) in the same manner. In another embodiment, the length of the opening 4531 may gradually decrease from the first and second rigid reinforcement regions C7 and C8 toward the center of the total folding region C6, or may be formed in such a manner that the length thereof gradually increases. In another embodiment, the opening 4531 may be formed in such a manner 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, the plurality of openings 4531 may be arranged to gradually increase or decrease their lengths 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 to gradually increase the length thereof in the flexible portion 453 as proceeding from the edges near the first flat portion 451 and the second flat portion 452 toward the central portion in the second direction (x-axis direction). This is because relatively large flexibility is required as the flexible portion 453 travels from the first flat portion and the second flat portion toward the center portion. In other words, this may mean that the bending characteristics of the flexible portion 453 may be adjusted to have a relatively high stiffness as going from the central portion of the bending portion 453a to the first and second

lower attachment portions

453b and 453 c. In another embodiment, the length of the opening 4531 may be formed to gradually decrease or gradually increase in the first direction (y-axis direction) and/or the second direction (x-axis direction) only in at least a partially defined portion of the total folding area C6. In another embodiment, the length of opening 4531 may vary irregularly rather than gradually.

Fig. 14a is a partial cross-sectional view illustrating a stacked structure of a display 1400 according to various embodiments of the present disclosure.

The display 130 of fig. 14a may be at least partially similar to the display 130 of fig. 3 or may also include other components of a display.

Referring to fig. 14a, a 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) arranged in sequence at the display panel 430, the blocking member 475 (e.g., the polymer layer) being 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 form a polymer layer and include at least one of TPU, silicone, rubber, or polyurethane. According to an embodiment, the display 1400 may be arranged to span at least a portion of a first surface (e.g., the first surface 111 of fig. 1) of the 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 the second housing structure 120 (e.g., the second housing structure 120 of fig. 1). According to an embodiment, the display 1400 may include a first region h1, a second region h2, and a third region h3, the first region h1 being a flat region corresponding to the first housing structure 110 of the electronic device (e.g., the electronic device 100 of fig. 1), the second region h2 being a flat region corresponding to the second housing structure 120, the third region h3 facing the hinge structure (e.g., the hinge structure 164 of fig. 3). According to an embodiment, the first and second regions h1 and h2 of the display 1400 may be configured to be folded or unfolded with respect to each other based on at least a portion of the third region h 3. 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 curved portion 453a that may be folded and first and second

lower attachment portions

453b and 453c extending to both sides of the curved portion 453a and connected to the first and second

flat portions

451 and 452, respectively.

According to various embodiments, the at least one polymer member 440 may include a buffer layer 441 and first and second layers 442 (e.g., first and second polymer layers) 443 (e.g., second polymer layers) stacked with the buffer layer 441 interposed therebetween. According to one embodiment, the at least one polymer member 440 may have a stacked structure for blocking foreign substances from passing through the plurality of openings 4531 formed in the flexible portion 453 of the conductive plate 450 and preventing visibility of the folding boundary area 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 material for buffering (e.g., sponge or foam). According to an embodiment, the first layer 442 (e.g., a first polymer layer) disposed on the buffer layer and the second layer 443 (e.g., a second polymer layer) disposed under the buffer layer 441 may be made of a material (e.g., TPU) for improving surface quality (e.g., improving visibility). According to an embodiment, the surface roughness of the first layer 442 (e.g., a first polymer layer) and the surface roughness of the second layer 443 (e.g., a second polymer layer) may be the same or different. For example, to improve visibility, the surface roughness of the first layer may be lower than the surface roughness of the second layer 443 (e.g., the second polymer layer).

According to various embodiments, the display panel 430, the at least one polymer member 440, the conductive plate 450, and the blocking member 475 (e.g., a polymer layer) may be attached to each other by the

adhesive members

551, 552, 553, and 554. For example, the

adhesive members

551, 552, 553, and 554 may include at least one of Optically Clear Adhesive (OCA), Pressure Sensitive Adhesive (PSA), heat reactive adhesive, general adhesive, or double-sided tape. According to an embodiment, the at least one polymer member 440 may be attached to the rear surface of the display panel 430 by the first adhesive member 551. According to an embodiment, the conductive plate 450 may be attached to the rear surface of the polymer member 440 by the second adhesive member 552.

According to an embodiment, the blocking member 475 (e.g., a polymer layer) may be attached to the rear surface of the conductive plate 450 by the third adhesive member 553. According to an embodiment, the display 1400 may be at least partially attached to the first and

second housing structures

110 and 120 by the fourth and fifth

adhesive members

554 and 555.

According to various embodiments, the barrier member 475 (e.g., a polymer layer) may be at least partially attached to the first and

second housing structures

110, 120 by a fourth adhesive member 554. According to one embodiment, the blocking member 475 (e.g., a polymer layer) attached to the first and

second housing structures

110 and 120 by the fourth adhesive member 554 may include the first and second

lower attachment portions

453b and 453c without including an area overlapping with the bending portion 453a of the flexible portion 453 when viewed from above the display. This may provide a non-adhesive portion to an area of the blocking member 475 (e.g., a polymer layer) corresponding to the bending portion 453a, thereby alleviating a stress concentration phenomenon due to the folding operation and separating the first and

second case structures

110 and 120 from the surface of the display 1400 during the folding operation. In another embodiment, the non-adhesive portion may be disposed to overlap with an area larger than the bending portion 453a and smaller than the flexible portion 453 when viewed from above the display 1400. In another embodiment, the non-adhesive portion may be arranged to overlap with an area larger than the flexible portion 453 when viewed from above the display 1400. According to one embodiment, the conductive plate 450 may be directly attached to the first and

second housing structures

110 and 120 by the 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 thickness of the third adhesive member 553, the barrier member 475 (e.g., a polymer layer), and the fourth adhesive member 554. According to one embodiment, the fifth adhesive member 555 may include a double-sided adhesive tape or a waterproof adhesive tape.

Fig. 14b is a partial cross-sectional view of the display 1400 showing a folded structure of the conductive plates in a folded state, according to various embodiments of the present disclosure.

Referring to fig. 14b, the 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 and second

flat portions

451, 452 and providing bending properties at least partially through the plurality of openings 4531. According to an embodiment, the flexible portion 453 may include a curved portion 453a that is curved 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 an embodiment, in order to solve a stress concentration phenomenon generated at the periphery of each of the

flat portions

451 and 452 due to the folding operation of the conductive plate 450, the first and second

lower attachment portions

453b and 453c may be attached to the first and

second case structures

110 and 120, respectively. For example, when the flexible portion 453 is overlapped with the bending portion 453a, stress is concentrated on both left and right ends of the bending portion 453a, and there may occur a problem that the connection portion is disconnected by the opening 4531 due to a folding or unfolding operation of the electronic apparatus in the corresponding region. Accordingly, stress concentrated in the stress concentration region due to the folding or unfolding operation of the electronic device may be relaxed by the first and second

lower attachment portions

453b and 453c of the first and

second case structures

110 and 120, which are at least partially attached to the curved portion 453a by the extension of the opening 4531.

According to various embodiments, the areas of the first and second

lower attachment portions

453b and 453c may be determined by end points of the final opening 4531 disposed at left and right ends of the flexible portion 453 from the bent portion 453a, a point including at least a portion of the first and second

flat portions

451 and 452 after the end point of the final opening 4531, or a point including a portion of the final opening 4531.

Fig. 15a is a diagram illustrating a back surface of a display 1500 according to various embodiments of the present disclosure. Fig. 15b is a diagram illustrating a state in which the first reinforcing plate 510 and the second reinforcing plate 520 are arranged next to each other according to various embodiments of the present disclosure.

Display 1500 of fig. 15a may be at least partially similar to display 130 of fig. 3 or may also include other components of a display.

When describing fig. 15a and 15b, at least some components of the display 1500 may be substantially the same as those of fig. 4c, the same reference numerals may be used for the same components, and detailed descriptions thereof may be omitted.

Referring to fig. 15a and 15b, the display 1500 may include a pair of reinforcing

plates

510 and 520 disposed at the rear surface of the conductive plate 450 to assist in rigid reinforcement of the display 1500. According to one embodiment, the pair of reinforcing

plates

510 and 520 may include a first reinforcing plate 510 arranged to extend 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 and a second reinforcing plate 520 arranged to extend from at least a portion of the 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 and second reinforcing

plates

510 and 520 may be formed in a shape avoiding the structure disposed at the rear surface of the conductive plate 450. For example, the first and

second reinforcement plates

510 and 520 may be formed in a shape avoiding the adhesive member P4 arranged 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 in a shape avoiding the extension portion 431, the connection pad 434, and the FPCB 432 folded from the display panel (e.g., the display panel 430 of fig. 4 c) and may be disposed at the rear surface of the conductive plate 450. This may prevent an increase in thickness of the display 1500 due to the stacking of the reinforcing

plates

510 and 520.

According to various embodiments, the first and

second reinforcement plates

510 and 520 may be arranged to have different gaps g1, g2, and g3, the different gaps g1, g2, and g3 having at least partially different spacings from each other based on the axis a in the flexible portion of the conductive plate 450. These gaps g1, g2, and g3 may cause the first and second reinforcing

plates

510 and 520 to be folded together with the first and second

flat portions

451 and 452 of the conductive plate 450 when the display 1500 is folded based on the flexible portion 453.

According to various embodiments, the first reinforcement plate 510 and the second reinforcement plate 520 may be disposed to face each other with the first gap g1 over a substantially majority of area. According to an embodiment, the first reinforcing plate 510 may include first and

second extension portions

511 and 512 for covering upper and lower end regions (regions C8 and C9) of the flexible portion 453 of the conductive plate 450. According to an embodiment, the second reinforcement plate 520 may include third and

fourth extension parts

521 and 522 for covering upper and lower end regions C8 and C9 of the flexible portion 453 of the conductive plate 450. According to an embodiment, the first and

third extension portions

511 and 521 may be disposed to face each other with a second gap g2 smaller than the first gap g 1. According to an embodiment, the second and

fourth extension portions

512 and 522 may also be disposed to face each other with the second gap g 2. According to an embodiment, the first and

second reinforcement plates

510 and 520 may be arranged to have a third gap g3 greater than the first gap g1 in at least some regions facing each other. The region of the third gap g3 having a larger interval may assist the arrangement space of the electrical connection member (e.g., FPCB) (e.g., the at least one wiring member 163 of fig. 3) extending from the first inner space of the first case structure 110 of the electronic device to the second inner space of the second case structure 120 through the hinge structure. According to an embodiment, to form the first gap g1, the second gap g2, and/or the third gap g3, the first reinforcement plate 510 and the second reinforcement plate 520 may be formed to have a protrusion at least partially protruding from an edge of the region or to include a concave notch. 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 a magnetization phenomenon caused by at least one magnet of the member to be detected, which is disposed inside the electronic device and used as a detection sensor (e.g., a hall sensor).

According to various embodiments, the display 1500 may further include at least one additional adhesive member 540, the at least one additional adhesive member 540 being arranged in the longitudinal direction around the region of the gaps g1, g2, and g3 facing each other on the rear surfaces of the first reinforcing plate 510 and the second reinforcing plate 520. According to one embodiment, by adding the adhesive member 540, it is possible to prevent bending deformation of the first reinforcing plate 510 and the second reinforcing plate 520 generated in the portions of the gaps g1, g2, and g3 due to the folding operation or deformation and lifting due to a drop impact.

According to various embodiments, the first and

second reinforcement plates

510 and 520 may include attachment areas PA1 and PA2, respectively, attached at the rear surface of the conductive plate 450 at least partially by adhesive members.

Referring to fig. 16a, the first reinforcement plate 510 may be attached to at least a portion of the first attachment area PA1 of the conductive plate 450 by an adhesive member. According to one embodiment, the first attachment region PA1 may include a region that extends 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., the first lower attachment portion 453b of fig. 13 b). According to an embodiment, the second reinforcement plate 520 may be attached to at least a portion of the second attachment area PA2 of the conductive plate 450 by an adhesive member. According to one embodiment, the second attachment region PA2 may include a region that extends 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., the second lower attachment portion 453c of fig. 13 b).

Referring to fig. 16b, the first attachment area PA1 to which the first reinforcement plate 510 is attached may include an area corresponding to at least a portion of the first flat portion 451 of the conductive plate 450 except for the flexible portion 453. According to an embodiment, the second attachment region PA2 to which the second reinforcement plate 520 is attached may include a region corresponding to at least a part of the second flat portion 452 of the conductive plate 450 other than the flexible portion 453. For example, the first and second attachment areas PA1, PA2 may or may not at least partially include the flexible portion 453 of the conductive plate 450 depending on the bending characteristics at least partially required for the flexible portion 453.

Fig. 17 is an enlarged view illustrating a region C10 of fig. 15a according to various embodiments of the present disclosure.

Referring to fig. 17, the first and

second extension portions

511 and 512 of the first reinforcing plate 510, and the third and

fourth extension portions

521 and 522 of the second reinforcing plate 520 may be formed to have a protruding amount t2 protruding at least further than the flexible portion 453, so as to support and protect the upper and lower edges of the flexible portion 453 in a third region (e.g., a third region h3 of fig. 4 b) of a display (e.g., the display 400 of fig. 4 b). According to an embodiment, the first and

second extension portions

511 and 512 and the third and

fourth extension portions

521 and 522 of the second reinforcement plate 520 may extend to protrude further than the display panel 430.

Fig. 18 and 19 are partial sectional views illustrating a stacked structure of

displays

1500 and 1600 according to various embodiments of the present disclosure.

The

displays

1500 and 1600 of fig. 18 and 19 may be at least partially similar to the display 130 of fig. 3 or may include other components of the display.
