Description

Technical Field

[0001] Embodiments of the present invention relate to an electronic device including a foldable flexible plate.

Background Art

[0002] As the functional gap between each manufacturer of electronic devices decreases significantly, the electronic devices are gradually being slimmed down to meet the purchasing needs of consumers, enhanced in rigidity, strengthened in design aspects, and improved to differentiate their functional elements. Such electronic devices are deviating from a uniform rectangular shape and gradually transforming into various shapes. For example, an electronic device has a deformable structure that is convenient for carrying and can utilize a large-screen display when used. As part of such electronic devices, foldable-type electronic devices are constantly being launched, and an improved support structure for a folding display is required.

[0003] A foldable electronic device can include a hinge structure and a first housing structure and a second housing structure that are connected to each other in opposite directions by the hinge structure. Such a foldable electronic device operates in an infolding manner and / or an outfolding manner by rotating the first housing structure relative to the second housing structure within a range of 0 degrees to 360 degrees via the hinge structure. A foldable electronic device includes a flexible display disposed across the first housing structure and the second housing structure in a state of being opened at 180 degrees. Generally, an electronic device having a single housing (e.g., a bar-type electronic device) can be disposed behind the display within the internal space and help strengthen the rigidity by supporting the display, and includes at least one flexible plate provided for noise shielding.

[0004] Such flexible plates are grounded to the ground of a printed circuit board located inside an electronic device via an electrical connecting member. In the case of a foldable electronic device, a hinge structure allows the first housing structure and the second housing structure to move relative to each other, thereby separating them. Therefore, in the case of flexible plates that cannot be folded, each housing structure is separated and arranged into two flexible plates. In a flexible plate separation structure, frequent folding movements of the electronic device can cause creases to form on the corresponding parts of the display facing the edges of each flexible plate near the hinge structure. Such creases can cause malfunctions in the electronic device and reduce its operational reliability. [Overview of the project] [Problems that the invention aims to solve]

[Modes for carrying out the invention]

[0011] Figure 1 shows the unfolded state of the electronic device 100 according to an embodiment of the present invention, and Figure 2 shows the folded state of the electronic device 100 of Figure 1 according to an embodiment of the present invention.

[0012] Referring to Figures 1 and 2, the electronic device 100 includes a pair of housing structures (110, 120) (e.g., a foldable housing structure), a hinge cover 165, and a display 130 (e.g., a flexible display or a foldable display).

[0013] According to one embodiment of the present invention, a pair of housing structures (110, 120) (e.g., foldable housing structures) are rotatably coupled via a hinge structure (e.g., hinge structure 164 in Figure 3) so as to fold relative to one another. According to one embodiment, the hinge cover 165 covers the foldable portion of a pair of housing structures (110, 120). According to one embodiment, the display 130 (for example, a flexible display or a foldable display) is placed in a space formed by a pair of housing structures (110, 120).

[0014] In this specification, the side on which the display 130 is positioned is defined as the front of the electronic device 100, and the side opposite the front is defined as the rear of the electronic device 100. Furthermore, the surface enclosing the space between the front and rear surfaces is defined as the side surface of the electronic device 100. In one embodiment, a pair of housing structures (110, 120) includes a first housing structure 110 containing a sensor area 131d, a second housing structure 120, a first rear cover 140, and a second rear cover 150. The pair of housing structures (110, 120) of the electronic device 100 are not limited to the forms and combinations shown in Figures 1 and 2, but may be embodied by other shapes or combinations and / or combinations of parts. For example, in other embodiments, the first housing structure 110 and the first rear cover 140 can be formed integrally, and the second housing structure 120 and the second rear cover 150 can be formed integrally.

[0015] According to one embodiment, the first housing structure 110 and the second housing structure 120 are arranged on both sides of the folding axis (A axis) and have an overall symmetrical shape with respect to the folding axis (A axis). According to one embodiment, the angle and distance between the first housing structure 110 and the second housing structure 120 change depending on whether the state of the electronic device 100 is in an unfolded state (flat state), a folded state (folding state), or an intermediate state.

[0016] According to one embodiment, the first housing structure 110 differs from the second housing structure 120 in that it further includes a sensor area 131d on which various sensors are arranged. Outside of the sensor region 131d, the first housing structure 110 and the second housing structure 120 have symmetrical shapes. In another embodiment, the sensor placement area 131d may be further placed or replaced in at least a portion of the second housing structure 120.

[0017] In one embodiment, the first housing structure 110 is connected to a hinge structure (for example, the hinge structure 164 in Figure 3) when the electronic device 100 is deployed. The first housing structure 110 includes a first surface 111 positioned facing the front of the electronic device 100, a second surface 112 facing in the opposite direction from the first surface 111, and a first side member 113 enclosing 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 includes a first side surface 113a arranged parallel to the folding axis (A axis), 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 (A axis) and parallel to the second side surface 113b.

[0018] In one embodiment, the second housing structure 120 is connected to a hinge structure (for example, the hinge structure 164 in Figure 3) when the electronic device 100 is deployed. The second housing structure 120 includes a third surface 121 positioned facing the front of the electronic device 100, a fourth surface 122 facing in the opposite direction from the third surface 121, and a second side member 123 enclosing 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 includes a fourth side 123a arranged parallel to the folding axis (A axis), a fifth side 123b extending from one end of the fourth side 123a in a direction perpendicular to the folding axis (A axis), and a sixth side 123c extending from the other end of the fourth side 123a in a direction perpendicular to the folding axis (A axis) and parallel to the fifth side 123b. In one embodiment, the first surface 111 faces the third surface 121 when folded.

[0019] In one embodiment, the electronic device 100 includes a recess 101 formed to receive a display 130 via a structural connection between a first housing structure 110 and a second housing structure 120. Recess 101 is substantially the same size as display 130. In one embodiment, for the sensor area 131d, the recess 101 has two or more different widths in a direction perpendicular to the folding axis (A-axis).

[0020] For example, recess 101 has a first width (w1) between a first portion 110a formed at the edge of the sensor area 131d within the first housing structure 110 and a second portion 120a parallel to the folding axis (A-axis) of the second housing structure 120, and a second width (w2) formed by a third portion 110b parallel to the folding axis (A-axis) and not corresponding to the sensor area 113d within the first housing structure 110 and a fourth portion 120b of the second housing structure 120. In this case, the second width (w2) is formed to be longer than the first width (w1). For example, the recess 101 is formed to have a first width (w1) that extends from the first part 110a of the first housing structure 110, which has an asymmetrical shape, to the second part 120a of the second housing structure 120, and a second width (w2) that extends from the third part 110b of the first housing structure 110, which has an asymmetrical shape, to the fourth part 120b of the second housing structure 120.

[0021] In one embodiment, the first portion 110a and the third portion 110b of the first housing structure 110 are formed to be at different distances from each other from the folding axis (A axis). The width of recess 101 is not limited to the example shown in the figure. In the embodiment, the recess 101 may have two or more different widths depending on the shape of the sensor area 131d or the asymmetrical shape of the first housing structure 110 and 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 formed from a metallic or non-metallic material of a rigidity of a size selected to support the display 130.

[0022] In one embodiment, the electronic device 100 consists of electronic components for performing various functions, which are arranged to be exposed on the front of the electronic device 100 via the sensor area 131d or via one or more openings provided in the sensor area 131d. In one embodiment, the electronic components may include, for example, at least one of a front camera device, a receiver, a proximity sensor, an illuminance sensor, an iris recognition sensor, an ultrasonic sensor, or an indicator.

[0023] In one embodiment, the first rear cover 140 is positioned on the second surface 112 of the first housing structure 110. The first rear cover 140 has a substantially rectangular periphery. In one embodiment, at least a portion of the edge is surrounded by the first housing structure 110. Similarly, the second rear cover 150 is positioned on the fourth surface 122 of the second housing structure 120, and at least a portion of its edge is enclosed by the second housing structure 120.

[0024] In one embodiment, the first rear cover 140 and the second rear cover 150 have substantially symmetrical shapes based on the folding axis (A axis). In other embodiments, the first rear cover 140 and the second rear cover 150 may include a variety of shapes that differ from each other. In other embodiments, the first rear cover 140 may be integrally formed with the first housing structure 110, and the second rear cover 150 may be integrally formed with the second housing structure 120.

[0025] In one embodiment, the first rear cover 140, the second rear cover 150, the first housing structure 110, and the second housing structure 120 provide space through interconnected structures that can accommodate various components of the electronic device 100 (e.g., printed circuit boards, antenna modules, sensor modules, or batteries). In one embodiment, one or more components are arranged on or visually exposed on the rear surface of the electronic device 100. For example, one or more components or sensors are visually exposed through the first rear region 141 of the first rear cover 140. In one embodiment, the sensor includes a proximity sensor, a rear camera device, and / or a flash. In other embodiments, at least a portion of the sub-display 152 is visually exposed through the second rear area 151 of the second rear cover 150. In other embodiments, the electronic device 100 includes a speaker module 153 positioned through at least a portion of the second rear cover 150.

[0026] In one embodiment, the display 130 is placed in a space formed by a pair of housing structures (110, 120). For example, the display 100 can be mounted in a recess 101 formed by a pair of housing structures (110, 120) and positioned to occupy substantially the entire front surface of the electronic device 100. Therefore, the front surface of the electronic device 100 includes the display 130 and a portion of the first housing structure 110 adjacent to the display 130 (e.g., the edge region) and a portion of the second housing structure 120 (e.g., the edge region).

[0027] In one embodiment, the rear surface of the electronic device 100 includes a first rear cover 140, a portion of the first housing structure 110 adjacent to the first rear cover 140 (e.g., an edge region), a second rear cover 150, and a portion of the second housing structure 120 adjacent to the second rear cover 150 (e.g., an edge region).

[0028] In one embodiment, the display 130 means a display in which at least a portion of the area is deformable into a flat or curved surface. In one embodiment, the display 130 includes a folding area 131c, a first area 131a located on one side of the folding area 131c (for example, the area to the right of the folding area 131c), and a second area 131b located on the other side (for example, the area to the left of the folding area 131c). For example, the first region 131a is located on the first surface 111 of the first housing structure 110, and the second region 131b is located on the third surface 121 of the second housing structure 120.

[0029] In one embodiment, the regional divisions of the display 130 are illustrative, and the display 130 is divided into multiple (for example, four or more or two) regions according to its structure or function. For example, in the embodiment shown in Figure 1, the area of ​​the display 130 is distinguished by a folding region 131c or a folding axis (A axis) that extends parallel to the y axis. In other embodiments, the display 130 distinguishes regions based on other folding regions (e.g., folding regions parallel to the x-axis) or other folding axes (e.g., folding axes parallel to the x-axis).

[0030] The above-described division of the display area is merely a physical division by a pair of housing structures (110, 120) and a hinge structure (e.g., hinge structure 164 in Figure 3), and the display 130 substantially displays a single full screen through the pair of housing structures (110, 120) and hinge structure (e.g., hinge structure 164 in Figure 3). In one embodiment, the first region 131a and the second region 131b have an overall symmetrical shape with respect to the folding region 131c. However, unlike the second region 131b, the first region 131a includes a notch region (for example, the notch region 133 in Figure 3) that is cut in response to the presence of the sensor region 131d, but the other regions have a shape symmetrical to that of the second region 131b. For example, the first region 131a and the second region 131b may include a portion having a symmetrical shape and a portion having an asymmetrical shape.

[0031] The hinge cover 165 shown in Figure 2 is positioned between the first housing structure 110 and the second housing structure 120 and is configured to cover the internal components (for example, the hinge structure 164 in Figure 3). In one embodiment, the hinge cover 165 is covered by a portion of 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 (flat state or folded state).

[0032] For example, as shown in Figure 1, when the electronic device 100 is in the deployed state, the hinge cover 165 may be covered by the first housing structure 110 and the second housing structure 120 and not exposed. For example, as shown in Figure 2, when the electronic device 100 is in a folded state (for example, a completely folded state), the hinge cover 165 is exposed to the outside between the first housing structure 110 and the second housing structure 120. For example, in an intermediate state where the first housing structure 110 and the second housing structure 120 are folded at a certain angle, the hinge cover 165 is at least partially exposed to the outside of the electronic device 100 between the first housing structure 110 and the second housing structure 120. In this case, the exposed area may be less than when it is fully folded. In one embodiment, the hinge cover 165 includes a curved surface.

[0033] The operation of the first housing structure 110 and the second housing structure 120, and the respective areas of the display 130, depending on the operating state of the electronic device 100 (for example, the unfolded state (flat state) and the folded state), will be described below. In one embodiment, when the electronic device 100 is in a flat state (for example, the state in Figure 1), the first housing structure 110 and the second housing structure 120 are at an angle of 180 degrees, and the first region 131a and the second region 131b of the display are arranged to face the same direction. Furthermore, the folding region 131c forms the same plane as the first region 131a and the second region 131b. In another embodiment, when the electronic device 100 is in a flat state, the first housing structure 110 rotates 360 degrees relative to the second housing structure 120 and folds in the opposite direction so that the second surface 112 and the fourth surface 122 face each other.

[0034] In one embodiment, when the electronic device 100 is in a folded state (for example, the state shown in Figure 2), the first housing structure 110 and the second housing structure 120 are arranged facing each other. The first region 131a and the second region 131b of the display 130 face each other, forming a narrow angle (for example, between 0 and 10 degrees). The folding region 131c is formed by a curved surface having a predetermined curvature, at least in part.

[0035] In one embodiment, when the electronic device 100 is in an intermediate state, the first housing structure 110 and the second housing structure 120 are arranged at a certain angle to each other. The first region 131a and the second region 131b of the display 130 form an angle that is larger than in the folded state and smaller than in the unfolded state. The folding region 131c consists of a curved surface having a predetermined curvature, at least in part, and this curvature is smaller than that in the folded state.

[0036] Figure 3 is a separated perspective view of an electronic device 100 according to an embodiment of the present invention. Referring to Figure 3, the electronic device 100 according to an embodiment of the present invention includes a display 130, a support member assembly 160, at least one printed circuit board 170, a first housing structure 110, a second housing structure 120, a first rear cover 140, and a second rear cover 150.

[0037] According to one embodiment, the display 130 includes a display panel 131 (for example, a flexible display panel) and one or more plates 132 or layers to which the display panel 131 is attached. In one embodiment, one or more plates 132 include a flexible plate (for example, the flexible plate 500 in Figures 4a and 5a) (for example, a Cu sheet or a SUS sheet) that is placed between the display panel 131 and the support member assembly 160. According to one embodiment, the flexible plate (for example, the flexible plate 500 in Figures 4a and 5a) includes a conductive metal.

[0038] According to one embodiment, the flexible plate (for example, the flexible plate 500 in Figures 4a and 5a) is formed to have substantially the same area as the display 130, and the area facing the folding area of ​​the display is formed to be bendable. The plate 132 includes at least one auxiliary material layer (e.g., a graphite member) that is positioned on the back of the display panel 131. In one embodiment, the plate 132 is formed in a shape corresponding to the display panel 131. For example, a portion of the first plate 132 is formed in a shape corresponding to the notch area 133 of the display panel 131.

[0039] The support member assembly 160 includes a first support member 161 (e.g., a first support plate), a second support member 162 (e.g., a second support plate), a hinge structure 164 positioned between the first support member 161 and the second support member 162, a hinge cover 165 that covers the hinge structure 164 when viewed from the outside, and at least one wiring member 163 (e.g., a flexible printed circuit board (FPCB)) that crosses the first support member 161 and the second support member 162.

[0040] In one embodiment, the support member assembly 160 is positioned between the plate 132 and at least one printed circuit board 170. For example, the first support member 161 can be positioned between the first region 131a of the display 130 and the first printed circuit board 171. The second support member 162 is positioned between the second region 131b of the display 130 and the second printed circuit board 172. In one embodiment, a wiring member 163 and at least a portion of a hinge structure 164 are arranged inside the support member assembly 160. The wiring member 163 is positioned in a direction that crosses the first support member 161 and the second support member 162 (for example, in the x-axis direction). The wiring member 163 is positioned perpendicular to the folding axis of the folding region 131c (for example, the y-axis or folding axis A in Figure 1) (for example, in the x-axis direction).

[0041] In one embodiment, at least one printed circuit board 170 includes a first printed circuit board 171 located on the side of the first support member 161 and a second printed circuit board 172 located on the side of the second support member 162. The first printed circuit board 171 and the second printed circuit board 172 are arranged inside the space formed by the support member assembly 160, the first housing structure 110, the second housing structure 120, the first rear cover 140, and the second rear cover 150. Components for realizing various functions of the electronic device 100 can be arranged on the first printed circuit board 171 and the second printed circuit board 172.

[0042] In one embodiment, a first printed circuit board 171 is placed in the first space of the first housing structure 110 formed via the first support member 161, and a first battery 191 is placed in a position facing the first sweeping hole 1611 of the first support member 161. Furthermore, at least one sensor module 181 or at least one camera module 182 is arranged in the first space of the first housing structure 110. The first housing structure 110 includes a window glass 183 positioned to protect at least one sensor module 181 and at least one camera module 182 at a location corresponding to the notch area 133 of the display 130. In one embodiment, a second printed circuit board 172 and a second battery 192 are placed in the second space of the second housing structure 120 formed via a second support member 162, at a position facing the second sweeping hole 1621 of the second support member 162.

The first region (h1) and the second region (h2) are configured to be foldable or unfoldable based on the third region (h3) (for example, the flexible portion 503 (h3) in Figure 5a (for example, the folding region).

[0050] According to one embodiment, the flexible plate 500 has a first planar portion 501 facing the first region of the display 400 (for example, the first region (h1) in Figure 4b), a second planar portion 502 facing the second region of the display 400 (for example, the second region (h2) in Figure 4b), and a flexible portion 503 facing the third region of the display 400 (for example, the third region (h3) in Figure 4b).

According to one embodiment, the flexible plate 500 is provided with flexibility of at least a portion of the flexible portion 503 via a conductive elastic member 460. According to one embodiment, the conductive elastic member 460 is formed to have an elongation ratio of about 1% or more.

[0052] According to one embodiment, the polymer member 440 is painted in a dark color (e.g., black) to help the background be visible when the display is off.

[0054] Figure 5a shows an electronic device 100 according to an embodiment of the present invention, and Figure 5b shows a flexible plate 500 according to an embodiment of the present invention. Referring to Figures 5a and 5b, the electronic device 100 (for example, the electronic device 100 in Figures 1 and 2, and the electronic device 100 in Figure 3) includes a first housing structure 401 (for example, the first housing structure 110 in Figures 1 and 2), a second housing structure 402 (for example, the second housing structure 120 in Figures 1 and 2), a first rear cover 404 (for example, the first rear cover 140 in Figures 1 and 2), a second rear cover 405 (for example, the second rear cover 150 in Figures 1 and 2), and a flexible plate 500 (the flexible plate 500 in Figure 4b).

[0055] According to one embodiment, the first housing structure 401 (e.g., the first housing structure 110 in Figures 1 and 2) and the second housing structure 402 (e.g., the second housing structure 120 in Figures 1 and 2) of the electronic device 100 (e.g., the electronic device 100 in Figures 1 and 2, and the electronic device 100 in Figure 3) are arranged on both sides of a folding axis (e.g., the A axis). The flexible plate 500 allows the first housing structure 401 and the second housing structure 402 to be folded and unfolded around a folding axis (e.g., axis A).

[0056] According to one embodiment, the first rear cover 404 and the second rear cover 405 are arranged substantially symmetrically with respect to the folding axis (A axis). The first housing structure 401, the second housing structure 402, the first rear cover 404, and the second rear cover 405 have a structure that is connected to one another. According to one embodiment, the flexible plate 500 is in the form of a conductive metal sheet and is used to help enhance the rigidity of the electronic device, shield against ambient noise, and dissipate heat emitted from surrounding heat dissipation components. According to one embodiment, the flexible plate 500 may include at least one of Cu, Al, SUS, or CLAD (for example, a laminated member in which SUS and Al are arranged alternately). In other embodiments, the flexible plate 500 may include other alloy materials.

[0057] According to one embodiment, the flexible plate 500 includes a first planar portion 501 facing a first region of the display (for example, the display 400 in Figure 4b) (for example, the first region (h1) in Figure 4b), a second planar portion 502 facing a second region of the display 400 (for example, the second region (h2) in Figure 4b), and a flexible portion 503 facing a third region of the display 400 (for example, the second region (h3) in Figure 4b). According to one embodiment, the flexible plate 500 is folded and unfolded together with the display panel (e.g., the display panel 430 in Figure 4b) with respect to a folding axis (e.g., axis A) via at least a portion of the flexible portion 503.

[0058] According to one embodiment, at least a portion of the flexible portion 503 is positioned to support the back of the display panel (for example, the display panel in Figure 4b) when bending occurs in the display (for example, the third region (h3) of the display 400 in Figure 4b). In another embodiment, the third region (h3) may correspond to at least a portion of the flexible portion 503.

[0059] According to one embodiment, the flexible plate 500 is positioned between a first region (e.g., the first region (h1) in Figure 4b) and a second region (e.g., the second region (h2) in Figure 4b) of a display (e.g., the display 400 in Figure 4b). According to one embodiment, the first planar portion 501 of the flexible plate 500 includes a first support portion 510 that supports a first region (e.g., the first region (h1) in Figure 4b) of a display (e.g., the display 400 in Figure 4b). According to one embodiment, the second planar portion 502 of the flexible plate 500 includes a second support portion 520 that supports a second region (e.g., the second region (h2) in Figure 4b) of a display (e.g., the display 400 in Figure 4b).

[0060] The flexible portion 503 of the flexible plate 500 includes slits 530 formed at regular or irregular intervals and a plurality of support pieces 540. The first flat portion 501 of the flexible plate 500 is composed only of the first support portion 510 without the slit 530, and the second flat portion 502 is composed only of the second support portion 520 without the slit 530. Multiple support pieces 540 of the flexible section 503 are arranged to be connected to one another. As another example, the multiple support pieces 540 of the flexible portion 503 may be separated from one another. Because a slit 530 is formed in the flexible portion 503, the overall weight of the flexible plate 500 can be reduced, flexibility is ensured by the slit 530, and folding and unfolding operations can be easily performed in the third region (h3) (for example, the folding region).

[0061] According to one embodiment, a conductive elastic member (for example, the conductive elastic member 460 in Figure 4b) for connecting a plurality of support pieces 540 of the flexible portion 503 is arranged at the bottom of the flexible plate 500. For example, the conductive elastic member (e.g., the conductive elastic member 460 in Figure 4b) is positioned on the side of the flexible plate 500 that faces away from the side facing the display panel (e.g., the display panel 430 in Figure 4b). In one embodiment, the conductive elastic member (for example, the conductive elastic member 460 in Figure 4b) is arranged to overlap with at least a portion of the first planar portion 501, at least a portion of the second planar portion 502, and the entirety of the flexible portion 503.

[0062] The first planar portion 501, the second planar portion 502, and the flexible portion 503 are connected by a conductive elastic member (for example, the conductive elastic member 460 in Figure 4b). The multiple support pieces 540, separated (or detached) by the multiple slits 530, remain connected to one another via the conductive elastic member 460. Furthermore, the flexible portion 503 provides flexibility through multiple support pieces 540 that are separated by multiple slits 530 and connected via conductive elastic members 460. Furthermore, since the multiple slits 530 are closed via the conductive elastic member 460, it is possible to prevent foreign matter from flowing into the front surface of the flexible plate.

[0063] In one embodiment, the conductive elastic member 460 includes a conductive elastic tape member or a conductive elastic film member that is attached to the back surface of the flexible plate 500 from a part of the first planar portion 501 to at least a part of the second planar portion 502 via a plurality of support pieces 540. In one embodiment, the conductive elastic tape member may be formed from at least one of conductive rubber, conductive silicone, or conductive urethane. In one embodiment, the first planar portion 501 and the second planar portion 502 of the flexible plate 500, which are spaced apart from each other, are electrically connected to each other via a conductive elastic member 460. This electrically connects the ground area of ​​the printed circuit board (for example, the printed circuit board 170 in Figure 3) inside the electronic device 100 (for example, the electronic device 100 in Figure 3) with the flexible plate 500.

[0064] Figure 6 shows a flexible plate 600 according to an embodiment of the present invention.

[0065] According to one embodiment, the first housing structure 401 and the second housing structure 402 are folded and unfolded around a folding axis (e.g., axis A) by a flexible plate 600 (for example, the flexible plate 500 in Figure 4b). According to one embodiment, the flexible plate 600 is in the form of a conductive metal sheet and is used to help enhance the rigidity of the electronic device, shield against ambient noise, and disperse heat emitted from surrounding heat dissipation components. According to one embodiment, the flexible plate 600 may include at least one of Cu, Al, SUS, or CLAD (for example, a laminated member in which SUS and Al are arranged alternately). In other embodiments, the flexible plate 600 may include other alloy materials.

[0066] According to one embodiment, the flexible plate 600 includes a first planar portion 601 facing a first region of the display (e.g., the display 400 in Figure 4b) (e.g., the first region (h1) in Figure 4b), a second planar portion 602 facing a second region of the display 400 (e.g., the second region (h2) in Figure 4b), and a flexible portion 603 facing a third region of the display 400 (e.g., the third region (h3) in Figure 4b). According to one embodiment, the flexible plate 600 is folded and unfolded together with the display panel (e.g., the display panel 430 in Figure 4b) with respect to a folding axis (e.g., axis A) via at least a portion of the flexible portion 603.

[0067] According to one embodiment, at least a portion of the flexible portion 603 is positioned to support the back of the display panel (e.g., the display panel in Figure 4b) 430 when bending occurs in the display (e.g., the third region (h3) of the display 400 in Figure 4b). In another embodiment, the third region (h3) corresponds to at least a portion of the flexible portion 603. According to one embodiment, the flexible plate 600 is positioned between a first region (e.g., the first region (h1) in Figure 4b) and a second region (e.g., the second region (h2) in Figure 4b) of a display (e.g., the display 400 in Figure 4b).

[0068] According to one embodiment, the first planar portion 601 of the flexible plate 600 includes a first support portion 610 that supports a first region (e.g., the first region (h1) in Figure 4b) of a display (e.g., the display 400 in Figure 4b). According to one embodiment, the second planar portion 602 of the flexible plate 600 includes a second support portion 620 that supports a second region (e.g., the second region (h2) in Figure 4b) of a display (e.g., the display 400 in Figure 4b).

[0069] In one embodiment, the flexible portion 603 of the flexible plate 600 includes slits 630 and a plurality of support pieces 640 formed at regular or irregular intervals. For example, the slit 630 is formed in a bar shape. In one embodiment, the flexible portion 603 of the flexible plate 600 is arranged such that a plurality of support pieces 640 having a certain width w are spaced apart via slits 630 having a certain interval (d). The first flat portion 601 of the flexible plate 600 is composed only of the first support portion 610 without the slit 630, and the second flat portion 602 is composed only of the second support portion 620 without the slit 630.

[0070] According to one embodiment, the multiple support pieces 640 of the flexible portion 603 are arranged to be connected to one another. As another example, the multiple support pieces 640 of the flexible section 603 may be arranged to be spaced apart from one another. Because a slit 630 is formed in the flexible portion 603, the overall weight of the flexible plate 600 can be reduced, and the slit 630 ensures flexibility, making it easier to fold and unfold in the third region (h3) (for example, the folding region).

[0071] According to one embodiment, a conductive elastic member (for example, the conductive elastic member 460 in Figure 4b) for connecting a plurality of support pieces 640 of the flexible portion 603 is arranged at the bottom of the flexible plate 600. For example, the conductive elastic member (e.g., the conductive elastic member 460 in Figure 4b) is positioned on the side of the flexible plate 600 that faces away from the side facing the display panel (e.g., the display panel 430 in Figure 4b). In one embodiment, the conductive elastic member (for example, the conductive elastic member 460 in Figure 4b) is arranged to overlap with at least a portion of the first planar portion 601, at least a portion of the second planar portion 602, and the entirety of the flexible portion 603.

[0072] The first planar portion 601, the second planar portion 602, and the flexible portion 603 are connected by a conductive elastic member (for example, the conductive elastic member 460 in Figure 4b). The multiple support pieces 640, separated (or detached) by the multiple slits 630, remain connected to one another via the conductive elastic member 460. Furthermore, flexibility is provided to the flexible portion 603 via multiple support pieces 640 that are separated by multiple slits 630 and connected via conductive elastic members 460. Furthermore, since the multiple slits 630 are closed via the conductive elastic member 460, it is possible to prevent foreign matter from flowing into the front surface of the flexible plate.

[0073] According to one embodiment, the flexibility of the flexible portion 603 of the flexible plate 600 is determined by changing the shape and / or arrangement density of the multiple support pieces 640 and slits 630. According to one embodiment, the flexibility of the flexible portion 603 is determined by the change in the width w of the plurality of support pieces 640. For example, the flexibility of the flexible section 603 is adjusted by forming a plurality of support pieces 640 having equal intervals (d) such that the width w of each piece gradually increases or decreases as it moves left or right with respect to the folding axis (e.g., the A-axis). According to one embodiment, the flexibility of the flexible portion 603 can also be adjusted by forming it such that the spacing (d) between a plurality of support pieces 640 having the same width w gradually decreases or widens as it moves left or right with respect to the folding axis (e.g., the A axis). According to one embodiment, the flexible portion 603 adjusts its flexibility through a plurality of support pieces 640 having different widths and spacings (d) from each other.

[0074] In one embodiment, the first planar portion 601 and the second planar portion 602 of the flexible plate 600, which are spaced apart from each other, are electrically connected to each other via a conductive elastic member 460. This electrically connects the ground area of ​​the printed circuit board (e.g., printed circuit board 170 in Figure 3) within the electronic device 100 (e.g., the electronic device 100 in Figure 3) to the flexible plate 600.

Referring to Figure 7, the flexible plate 700 according to an embodiment of the present invention includes a first planar portion 701 that supports a first region (e.g., the first region (h1) in Figure 4b) of a display (e.g., the display 400 in Figure 4b), a second planar portion 702 that supports a second region (e.g., the second region (h2) in Figure 4b) of the display (e.g., the display 400 in Figure 4b), and a flexible portion 703 that supports a third region (e.g., the third region (h3) in Figure 4b) of the display (e.g., the display 400 in Figure 4b).

[0076] In one embodiment, the flexible portion 703 of the flexible plate 700 includes slits 730 and a plurality of support pieces 740 formed at regular or irregular intervals. For example, the slit 730 is formed in a bar shape. In one embodiment, the flexible portion 700 of the flexible plate 700 is arranged such that a plurality of support pieces 740 having a certain width are spaced apart via slits 730 having a certain interval between them. The first flat portion 701 of the flexible plate 700 is composed only of the first support portion 710 without the slit 730, and the second flat portion 702 is composed only of the second support portion 720 without the slit 730.

[0077] According to one embodiment, the slit 730 of the flexible portion 703 is formed in a shape in which the upper side 704 (e.g., in the y-axis direction) and the lower side 705 (e.g., in the -y-axis direction) are open based on the folding axis (e.g., the A-axis). Multiple support pieces 740 are separated by the slit 730 so as to be separated at regular intervals. The multiple support pieces 740, separated by the multiple slits 730, remain connected to one another via conductive elastic members (for example, the conductive elastic member 460 in Figure 4b). Furthermore, the flexible portion 703 provides flexibility to the multiple support pieces 740 connected via the conductive elastic member 460.

[0078] Figure 8 shows the material of the flexible plate 800 according to an embodiment of the present invention. Referring to Figure 8, according to one embodiment, the first planar portion 801 (for example, the first planar portion 701 in Figure 7) and the second planar portion 802 (for example, the second planar portion 702 in Figure 7) of the flexible plate 800 are formed from a single material.

Resin 810 is formed in the space between multiple support pieces (for example, multiple support pieces 740 in Figure 7). For example, the resin 810 may be a conductive elastic resin, and is formed by filling multiple slits in liquid form and then curing it.

[0080] By forming the flexible section 803 from different materials, durability against impacts applied to the front of the electronic device can be enhanced, and shear strength can be increased. Furthermore, by forming the flexible portion 803 from different materials, the repulsive force is increased and flexibility is ensured, making folding and unfolding operations easier in the third region (h3) (for example, the folding region).

The bridge section 912 connects the first support section 910 and the second support section 920. The slit 930 of the flexible portion 703 is formed in a configuration in which the lower side 905 (for example, in the -y axis direction) is open with respect to the folding axis (for example, the A axis).

[0084] In one embodiment, the upper portions 940a of a plurality of support pieces 940 are connected by a bridge portion 912. The intermediate portion 940b and the lower portion 940c of the multiple support pieces 940 are separated at a certain interval by the slit 930. Multiple support pieces 940 of the flexible section 703 are connected by the bridge section 912, and the upper part 904 of the flexible section 703 is formed flat, improving the surface quality of the flexible section 703.

[0085] In one embodiment, the multiple support pieces 940 maintain a state of being connected to one another via conductive elastic members (for example, the conductive elastic member 460 in Figure 4b).

In one embodiment, a plurality of support pieces 940 (for example, a plurality of support pieces 740 in Figure 7) are formed from carbon fiber reinforced plastic (for example, carbon fiber reinforced plastic 820 in Figure 8). A resin (e.g., resin 810 in Figure 8) is formed in the space between the multiple support pieces 940 (e.g., the multiple support pieces 740 in Figure 7). By forming the flexible section 903 from different materials, durability against impacts applied to the front of the electronic device can be enhanced, and shear strength can be increased. Furthermore, by forming the flexible portion 903 from different materials, the repulsive force is increased and flexibility is ensured, making it easier to fold and unfold in the third region (h3) (for example, the folding region).

[0087] Figure 10 shows a folding axis according to an embodiment of the present invention, and Figure 11 shows the orientation direction of the flexible plate along the folding axis according to an embodiment of the present invention. Referring to Figures 10 and 11, the electronic device 1000 (for example, the electronic device 100 in Figure 5a) includes a flexible plate 1100 (for example, the flexible plate 500 in Figure 5a). The flexible plate 1100 is formed from multiple layers (1110, 1120). The flexible plate 1100 has multiple layers (1110, 1120), including a first support layer 1110 and a second support layer 1120. In one embodiment, the first support layer 1110 is located at the uppermost end, and the second support layer 1120 is located below the first support layer 1110.

[0088] According to one embodiment, the first support layer 1110 of the flexible plate 1100 is formed from a single planar layer that supports a display panel (for example, the display panel 430 in Figure 4b). According to one embodiment, the second support layer 1120 of the flexible plate 1100 includes a first planar portion 1101 facing a first region of the display (e.g., the display 400 in Figure 4b) (e.g., the first region (h1) in Figure 4b), a second planar portion 1102 facing a second region of the display 400 (e.g., the second region (h2) in Figure 4b), and a flexible portion 1103 facing three regions of the second region of the display 400 (e.g., the third region (h3) in Figure 4b). According to one embodiment, the flexible plate 1100 is folded and unfolded together with the display panel (e.g., the display panel 430 in Figure 4b) based on a folding axis (e.g., axis A) via at least a portion of the flexible portion 1103.

[0089] According to one embodiment, at least a portion of the flexible portion 1103 is positioned to support the back of the display panel (e.g., the display panel in Figure 4b) 430 when bending occurs in the display (e.g., the third region (h3) of the display 400 in Figure 4b). According to one embodiment, the flexible portion 1103 of the flexible plate 1100 includes a plurality of slits 1130 and a plurality of support pieces 1140 formed at regular or irregular intervals. The first flat portion 1101 and the second flat portion 1102 of the flexible plate 1100 are constructed without slits 1130. Multiple support pieces 1140 of the flexible section 1103 are arranged to be connected to one another. As another example, the multiple support pieces 1140 of the flexible section 1103 can be separated from one another.

[0090] According to one embodiment, the first support layer 1110 is positioned above (for example, in the y-axis direction) with respect to the folding axis (for example, the A-axis), and the upper side (for example, in the y-axis direction) of the multiple slits 1130 of the flexible portion 1103 is formed in a closed state. The first support layer 1110 connects the first support section 1110 and the second support section 1120. The multiple slits 1130 of the flexible portion 1103 are formed in a configuration in which the lower side (for example, in the -y axis direction) is open with respect to the folding axis (for example, the A axis).

[0091] According to one embodiment, the first support layer 1110 of the flexible plate 1100 includes carbon fiber reinforced plastic (CFRP). According to one embodiment, the second support layer 1120 of the flexible plate 1100 includes carbon fiber reinforced plastic (CFRP). According to one embodiment, the orientation directions of the first support layer 1110 and the second support layer 1120 of the flexible plate 1100 are formed differently based on the folding axis 1001 of the electronic device 1000. For example, the same direction 1020 (e.g., the y-axis direction) as the folding axis 1001 of the electronic device 1000 is defined as the 0-degree orientation. For example, the direction 1010 (e.g., the x-axis direction) perpendicular to the folding axis 1001 is defined as a 90-degree orientation.

[0092] According to one embodiment, the first support layer 1110 of the flexible plate 1100 is oriented in a single direction. In one embodiment, the first support layer 1110 of the flexible plate 1100 is oriented (e.g., 0 degrees) in the same direction as the first direction (e.g., the folding axis 1001) (e.g., the A axis). According to one embodiment, the second support layer 1120 of the flexible plate 1100 is oriented in multiple directions. In one embodiment, the second support layer 1120 of the flexible plate 1100 is oriented in the same direction as the first direction (e.g., the folding axis 1001) (e.g., the A axis) (e.g., 0-degree orientation) and in the direction orthogonal to the second direction (e.g., the folding axis 1001) (e.g., the A axis) (e.g., 90-degree orientation).

[0093] In one embodiment, the flexible plate 1100 has a first support layer 1110 positioned on top of the flexible portion 1103 of the second support layer 1120, and the upper sides of the multiple support pieces 1140 of the flexible portion 1103 are connected by the first support layer 1110. Multiple support pieces 1140 of the flexible section 1103 are connected by the first support layer 1110, and the upper side of the flexible section 1103 is formed flat, reducing the step difference on the upper surface of the flexible plate 1100 and improving the surface quality. Furthermore, in the flexible plate 1100, the first support layer 1110 is oriented in the same first direction as the folding axis 1001 (e.g., axis A), and the second support layer 1120 is oriented in a second direction perpendicular to the first direction and the folding axis 1001 (e.g., axis A), thereby increasing shear strength and ensuring flexibility.

[0094] Figure 12 shows the orientation direction of the flexible plate along the folding axis according to an embodiment of the present invention. Referring to Figures 10 and 12, the electronic device 1000 (for example, the electronic device 100 in Figure 5a) includes a flexible plate 1200 (for example, the flexible plate 500 in Figure 5a). The flexible plate 1200 includes multiple layers (1210, 1220, 1230, 1240).

[0095] According to one embodiment, the flexible plate 1200 has multiple layers (1210, 1220, 1230, 1240) including a first support layer 1210, a second support layer 1220, a third support layer 1230, and a flexible layer 1240. In one embodiment, the first support layer 1210 is located at the uppermost unit, and the second support layer 1220 is positioned below the first support layer 1210. The third support layer 1230 is located below the second support layer 1220. The flexible layer 1240 is located below the first support layer 1210.

[0096] In one embodiment, the first support layer 1210 is positioned to face the entirety of the first planar portion 1201, the second planar portion 1202, and the flexible portion 1203. In one embodiment, the first support portion 1221 of the second support layer 1220 is positioned to overlap with the first planar portion 1201. The second support portion 1222 of the second support layer 1220 is positioned to overlap with the second planar portion 1202. The first support portion 1231 of the third support layer 1230 is positioned to overlap with the first planar portion 1201. The second support portion 1232 of the third support layer 1230 is positioned to overlap with the second planar portion 1202. In one embodiment, the second support layer 1220 and the third support layer 1230 are not formed at the positions facing the flexible portion 1203. In one embodiment, a flexible layer 1240 is placed in the flexible portion 1203 located between the first flat portion 1201 and the second flat portion 1202.

[0097] According to one embodiment, the flexible plate 1200 is folded and unfolded together with the display panel (e.g., the display panel 430 in Figure 4b) based on a folding axis (e.g., the A axis) via at least a portion of the flexible portion 1203 (e.g., the flexible layer 1240). According to one embodiment, at least a portion of the flexible portion 1203 is positioned to support the back of the display panel (e.g., the display panel 430 in Figure 4b) when bending occurs in the display (e.g., the third region (h3) of the display 400 in Figure 4b). According to one embodiment, the first support layer 1210 is positioned above (for example, in the y-axis direction) with respect to the folding axis (for example, the A-axis), and the upper side (for example, in the y-axis direction) of the flexible portion 1203 is formed in a closed form. The first support layer 1210 connects the first support portion 1221 and the second support portion 1222 of the second support layer 1220.

[0098] According to one embodiment, the first support layer 1210 of the flexible plate 1200 includes carbon fiber reinforced plastic (CFRP). According to one embodiment, the first support portion 1221 and the second support portion 1222 of the second support layer 1220 of the flexible plate 1200 include carbon fiber reinforced plastic (CFRP). According to one embodiment, the first support portion 1231 and the second support portion 1232 of the third support layer 1230 of the flexible plate 1200 include carbon fiber reinforced plastic (CFRP). According to one embodiment, the flexible layer 1240 may include a thermally conductive flexible composite resin (e.g., graphite composite), a soft graphite resin, and / or carbon fiber reinforced plastic (CFRP).

[0099] According to one embodiment, the orientation directions of the first support layer 1210, the second support layer 1220, and the third support layer 1230 of the flexible plate 1200 are different based on the folding axis 1001 of the electronic device 1000. For example, the same direction 1020 (e.g., the y-axis direction) as the folding axis 1001 of the electronic device 1000 is defined as the 0-degree orientation. For example, the direction 1010 (e.g., the x-axis direction) perpendicular to the folding axis 1001 is defined as a 90-degree orientation.

[0100] According to one embodiment, the first support layer 1210 of the flexible plate 1200 is oriented in a single direction. In one embodiment, the first support layer 1210 of the flexible plate 1200 is oriented (e.g., 0 degrees) in the same direction as the first direction (e.g., the folding axis 1001) (e.g., the A axis). According to one embodiment, the second support layer 1220 of the flexible plate 1200 is oriented in multiple directions. In one embodiment, the second support layer 1220 of the flexible plate 1200 is oriented (e.g., 0-degree orientation) in the same direction as the first direction (e.g., the folding axis 1001) (e.g., the A axis) (1020) and in a direction 1010 perpendicular to the second direction (e.g., the folding axis 1001) (e.g., the A axis) (e.g., 90-degree orientation).

[0101] According to one embodiment, the third support layer 1230 of the flexible plate 1200 is oriented in a single direction. In one embodiment, the third support layer 1230 of the flexible plate 1200 is oriented (e.g., 0 degrees) in the same direction 1020 as the first direction (e.g., folding axis 1001) (e.g., A axis). As another example, the third support layer 1230 of the flexible plate 1200 is oriented in a single direction. In one embodiment, the third support layer 1230 of the flexible plate 1200 is oriented (for example, 90-degree orientation) in a direction 1010 perpendicular to the second direction (for example, the folding axis 1001) (for example, the A-axis).

[0102] In one embodiment, the flexible plate 1200 has a first support layer 1210 positioned on top of the flexible layer 1240, and the upper side of the flexible portion 1103 is formed flat. This reduces the step difference on the upper surface of the flexible plate 1200 and improves the surface quality. Furthermore, the flexible plate 1200 is configured such that the first support layer 1210 is oriented in the same first direction as the folding axis 1001 (e.g., axis A), the second support layer 1220 is oriented in a second direction perpendicular to the first direction and the folding axis 1001 (e.g., axis A), and the third support layer 1230 is oriented in the first or second direction to increase shear strength and ensure flexibility.

[0103] Figure 13a shows a flexible plate for an electronic device according to an embodiment of the present invention, and Figure 13b shows the Velcro (registered trademark, hereinafter omitted) pattern of the flexible plate according to an embodiment of the present invention. Referring to Figures 13a and 13b, the electronic device 1300 (for example, the electronic device 100 in Figure 5a) includes a flexible plate 1310 (for example, the flexible plate 500 in Figure 5a). The flexible plate 1310 is formed from a single layer or multiple layers (for example, multiple layers in Figure 11 (1110, 1120), multiple layers in Figure 12 (1210, 1220, 1230, 1240)).

[0104] According to one embodiment, the flexible plate 1310 includes an eleventh planar portion 1311a facing a first region (h1) 1317 (for example, the first region (h1) in Figure 4b) of the display (for example, the display 400 in Figure 4b), a second planar portion 1311b facing a second region (h2) 1319 (for example, the second region (h2) in Figure 4b) of the display 400, and a flexible portion 1311c facing a third region (for example, the third region (h3) in Figure 4b) of the display 400. According to one embodiment, the flexible plate 1310 is folded and unfolded together with the display panel (e.g., the display panel 430 in Figure 4b) based on a folding axis (e.g., axis A) via at least a portion of the flexible portion 1311c.

[0105] According to one embodiment, at least a portion of the flexible portion 1311c is positioned to support the back of the display panel (e.g., the display panel 430 in Figure 4b) when bending occurs in the display (e.g., the third region (h3) of the display 400 in Figure 4b). According to one embodiment, the flexible portion 1311c of the flexible plate 1310 includes a plurality of slits 1316 and a plurality of support pieces 1312 formed at regular or irregular intervals, and a plurality of Velcro patterns 1314 extending from the plurality of support pieces 1312.

[0106] In one embodiment, the first flat portion 1311a and the second flat portion 1311b of the flexible plate 1310 are configured without a plurality of slits 1316 and a plurality of Velcro patterns 1314. The multiple support pieces 1312 of the flexible section 1311c are arranged to be separated from each other by multiple slits 1316. Multiple support pieces 1312 are connected by multiple Velcro patterns 1314. In one embodiment, the plurality of Velcro patterns 1314 include a first Velcro pattern 1314a whose length extends in a first direction (e.g., the x-axis direction) from the first side surface 1312a of the plurality of support pieces 1312, and a plurality of second Velcro patterns 1314b whose length extends in a second direction (e.g., the -x-axis direction) on the second side surface 1312b of the support piece 1312.

[0107] In one embodiment, a plurality of first Velcro patterns 1314a include a first portion (1314a-1) extending in a first direction (e.g., x-axis direction) from the first side surface 1312a of a plurality of support pieces 1312, and a second portion (1314a-2) extending in a third direction (e.g., y-axis direction) and a fourth direction (e.g., -y-axis direction) from the end of the first portion (1314a-1). The first part (1314a-1) is extended in length in a first direction (e.g., the x-axis direction), and the second part (1314a-2) is extended in length in a third direction (e.g., the y-axis direction) and a fourth direction (e.g., the -y-axis direction). In one embodiment, a plurality of second Velcro patterns 1314b include a third portion (1314b-1) whose length extends in a second direction (e.g., the -x axis direction) from the second side surface 1312b of a plurality of support pieces 1312, and a fourth portion (1314b-2) whose length extends in a third direction (e.g., the y axis direction) and a fourth direction (e.g., the -y axis direction) from the end of the third portion (1314b-1). The third section (1314b-1) is extended in length in the second direction (e.g., the -x axis direction), and the fourth section (1314b-2) is extended in length in the third direction (e.g., the y axis direction) and the fourth direction (e.g., the -y axis direction).

[0108] In one embodiment, the support piece 1312 is located in the center, the first Velcro pattern 1314a is located in one direction (e.g., in the x-axis direction) of the support piece 1312, and the second Velcro pattern 1314b is located in the other direction (e.g., in the -x-axis direction) of the support piece 1312. In another example, the support piece 1312 is centrally located, the second Velcro pattern 1314b is located on one side of the support piece 1312 (e.g., in the x-axis direction), and the first Velcro pattern 1314a is located on the other side of the support piece 1312 (e.g., in the -x-axis direction). In one embodiment, a first Velcro pattern 1314a and a second Velcro pattern 1314b, whose lengths are extended by a plurality of adjacent support pieces 1312, are arranged to engage with each other in a lattice shape, connecting the plurality of support pieces 1312.

[0109] In one embodiment, the first portion (1314a-1) of the first Velcro pattern 1314a and the third portion (1314b-1) of the second Velcro pattern 1314b are formed to have a first width (w1) (for example, about 0.05 mm). In one embodiment, the second portion (1314a-2) of the first Velcro pattern 1314a and the fourth portion (1314b-2) of the second Velcro pattern 1314b are formed to have a second width (w2) (for example, about 0.05 mm). In one embodiment, when it includes a support piece 1312, a first Velcro pattern 1314a, and a second Velcro pattern 1314b, it is formed to have a third width w3 (for example, about 0.2 mm).

[0110] In one embodiment, increasing the width of the support piece 1312 can increase the rigidity of supporting the display panel in the folding region. In one embodiment, increasing the widths of the first Velcro pattern 1314a and the second Velcro pattern 1314b increases the elongation rate of the flexible portion 1311c, thereby increasing the shear strength and ensuring flexibility. In one embodiment, by reducing the density of the support piece 1312, the first Velcro pattern 1314a, and the second Velcro pattern 1314b, and increasing the thickness of the first Velcro pattern 1314a and the second Velcro pattern 1314b, the tensile strength and shear strength can be improved.

[0111] Figure 14 shows a flexible plate in the folded state (e.g., closed state) of an electronic device according to an embodiment of the present invention. Referring to Figures 2 and 14, when the electronic device 100 is in a folded state (e.g., closed state), the gaps between the multiple slits 1316 formed in the flexible portion of the flexible plate 1310 (e.g., flexible portion 703 in Figure 7, flexible portion 903 in Figure 9, flexible portion 1103 in Figure 11, and flexible portion 1311c in Figure 13a) are extended to a first interval (d1).

[0112] For example, when the electronic device 100 is in a folded state (e.g., closed state), the display 130 is folded, which extends the spacing between the multiple slits 1316 in the flexible portion of the flexible plate 1310 in the folding region to its maximum (e.g., first spacing). Even if the distance between the multiple slits 1316 is extended to a first interval (d1), the multiple support pieces 1312 of the multiple Velcro patterns 1314 and the multiple second Velcro patterns 1314b are arranged to engage with each other in a lattice shape, allowing the multiple support pieces 1312 to be connected to each other without detaching.

[0113] Figure 15 shows a flexible plate in an open state (e.g., open state) of an electronic device according to an embodiment of the present invention. Referring to Figures 1 and 15, when the electronic device 100 is in an open state (for example, an open state), the gaps between the multiple slits 1316 formed in the flexible portion of the flexible plate 1310 (for example, flexible portion 703 in Figure 7, flexible portion 903 in Figure 9, flexible portion 1103 in Figure 11, and flexible portion 1311c in Figure 13a) are narrowed to a second interval (d2).

[0114] For example, when the electronic device 100 is in a folded state (e.g., closed state), the display 130 is unfolded, which narrows the spacing between the multiple slits 1316 in the flexible portion of the flexible plate 1310 in the folded area. Even if the gap between the multiple slits 1316 narrows to a second interval (d2), the multiple support pieces 1312 of the multiple Velcro patterns 1314 and the multiple second Velcro patterns 1314b are arranged to engage with each other in a lattice shape, allowing the multiple support pieces 1312 to be connected to each other without detaching.

[0115] Figure 16 shows a flexible plate in a compressed state. Referring to Figures 1, 2, and 16, when the electronic device 100 falls in a folded state (e.g., closed state) or an open state (e.g., open state), a strong unfolding pressure is instantaneously applied to the electronic device 100, causing the gaps between the multiple slits 1316 formed in the flexible portion of the flexible plate 1310 (e.g., flexible portion 703 in Figure 7, flexible portion 903 in Figure 9, flexible portion 1103 in Figure 11, and flexible portion 1311c in Figure 13a) to narrow to a third gap (d3).

[0116] For example, when pressure is applied by a user gripping the electronic device 100 in an open state (e.g., open state), a strong unfolding pressure is applied to the electronic device 100, narrowing the minimum spacing (e.g., third spacing (d3)) between the multiple slits 1316 formed in the flexible portion of the flexible plate 1310 (e.g., flexible portion 703 in Figure 7, flexible portion 903 in Figure 9, flexible portion 1103 in Figure 11, and flexible portion 1311c in Figure 13a). Even when the gaps between the multiple slits 1316 narrow to a third interval (d3), the multiple support pieces 1312 of the multiple Velcro patterns 1314 and the multiple second Velcro patterns 1314b are arranged to engage with each other in a lattice shape, and the multiple support pieces 1312 are connected to each other without detaching.

[0117] Figure 17 shows a flexible plate according to an embodiment of the present invention. Referring to Figure 17, the flexible plate 1700 according to an embodiment of the present invention is formed of a single layer or multiple layers (for example, multiple layers in Figure 11 (1110, 1120), multiple layers in Figure 12 (1210, 1220, 1230, 1240)).

[0118] According to one embodiment, the flexible plate 1700 includes a first planar portion 1701 facing a first region (e.g., the first region (h1) in Figure 4b) of the display (e.g., the display 400 in Figure 4b), a second planar portion 1702 facing a second region (e.g., the second region (h2) in Figure 4b) of the display 400, and a flexible portion 1703 facing a third region (e.g., the third region (h3) in Figure 4b) of the display 400. According to one embodiment, the flexible plate 1700 is folded and unfolded together with the display panel (e.g., the display panel 430 in Figure 4b) based on a folding axis (e.g., axis A) via at least a portion of the flexible portion 1703.

[0119] According to one embodiment, at least a portion of the flexible portion 1703 is positioned to support the back of the display panel (e.g., the display panel 430 in Figure 4b) when bending occurs in the display (e.g., the third region (h3) of the display 400 in Figure 4b). According to one embodiment, the flexible portion 1703 of the flexible plate 1700 includes a plurality of slits 1730 and a plurality of support pieces 1710 formed at regular or irregular intervals, and a plurality of Velcro patterns 1720 extending from the plurality of support pieces 1710.

[0120] According to one embodiment, the first flat portion 1701 of the flexible plate 1700 encloses the first support portion 1740. According to one embodiment, the first planar portion 1702 of the flexible plate 1700 includes a second support portion 1750. The first support section 1740 and the second support section 1750 are constructed without multiple slits 1730 and multiple support pieces 1710.

[0121] In one embodiment, the first flat portion 1701 and the second flat portion 1702 of the flexible plate 1700 are configured without a plurality of slits 1730 and a plurality of Velcro patterns 1720. The multiple support pieces 1710 of the flexible section 1703 are arranged to be separated from each other by multiple slits 1720. Multiple support pieces 1710 are connected by multiple Velcro patterns 1720. In one embodiment, the plurality of Velcro patterns 1720 include a first Velcro pattern 1722 whose length extends in a first direction (e.g., the x-axis direction) from the first side surface of the plurality of support pieces 1710, and a plurality of second Velcro patterns 1724 whose length extends in a second direction (e.g., the -x-axis direction) from the second side surface of the support piece 1710.

[0122] In one embodiment, the first Velcro pattern 1722 is formed in the shape of a "rightward-facing triangle" that widens as it extends from the first side surface of the support piece 1710 in the first direction (for example, the x-axis direction). In one embodiment, the second Velcro pattern 1724 is formed in the shape of a "left-facing triangle" that widens as it extends from the second side surface of the support piece 1710 in the second direction (for example, the -x axis direction).

[0123] In one embodiment, the support piece 1710 is located in the center, the first Velcro pattern 1722 is located in one direction (e.g., in the x-axis direction) of the support piece 1312, and the second Velcro pattern 1724 is located in the other direction (e.g., in the -x-axis direction) of the support piece 1710. As another example, the support piece 1710 is centrally located, the second Velcro pattern 1724 is located on one side of the support piece 1710 (e.g., in the x-axis direction), and the first Velcro pattern 1724 is located on the other side of the support piece 1710 (e.g., in the -x-axis direction). In one embodiment, a first Velcro pattern 1722 and a second Velcro pattern 1724, whose lengths are extended by a plurality of adjacent support pieces 1710, are arranged to engage with each other in a lattice shape to connect the support pieces 1710.

[0124] Figure 18 shows a flexible plate according to an embodiment of the present invention. Referring to Figure 18, the electronic device (e.g., the electronic device 100 in Figure 5a) includes flexible plates 1800 (e.g., flexible plate 900 in Figure 9, flexible plate 1100 in Figure 11, and flexible plate 1200 in Figure 12).

[0125] The flexible plate 1800 is formed from multiple layers (1810, 1820, 1830, 1822, 1832). The flexible plate 1800 has multiple layers (1810, 1820, 1830, 1822, 1832), including a first support layer 1810, a second support layer 1820, a third support layer 1830, a first skin layer 1822, and a second skin layer 1832. In one embodiment, the second support layer 1820 and the first skin layer 1822 are located at the uppermost end, and the first support layer 1810 is located below the second support layer 1820. The third support layer 1830 and the second skin layer 1832 are located below the first support layer 1810.

[0126] According to one embodiment, the flexible plate 1800 includes a first planar portion 1801 facing a first region (e.g., the first region (h1) in Figure 4b) of the display (e.g., the display 400 in Figure 4b), a second planar portion 1802 facing a second region (e.g., the second region (h2) in Figure 4b) of the display 400, and a flexible portion 1803 facing a third region (e.g., the third region (h3) in Figure 4b) of the display 400. According to one embodiment, the flexible plate 1800 is folded and unfolded together with the display panel (e.g., the display panel 430 in Figure 4b) based on a folding axis (e.g., axis A) via at least a portion of the flexible portion 1803.

[0127] According to one embodiment, at least a portion of the flexible portion 1803 is positioned to support the back of the display panel (e.g., the display panel 430 in Figure 4b) when bending occurs in the display (e.g., the third region (h3) of the display 400 in Figure 4b). In one embodiment, the second support layer 1820 is formed on the first planar portion 1801 and the second planar portion 1802, but not on the flexible portion 1803. The first skin layer 1822 is positioned on the flexible portion 1803 in the same plane as the second support layer 1820. The first skin layer 1822 is positioned in the space between the second support layers 1820. In one embodiment, the third support layer 1830 is formed on the first planar portion 1801 and the second planar portion 1802, but not on the flexible portion 1803. The second skin layer 1832 is positioned on the flexible portion 1803 in the same plane as the third support layer 1830. The second skin layer 1832 is positioned in the space between the third support layers 1830.

[0128] According to one embodiment, the flexible portion 1803 of the flexible plate 1800 includes a plurality of slits 1814 and a plurality of support pieces 1812 formed at regular or irregular intervals. Multiple slits 1814 and multiple support pieces 1812 are formed in the first support layer 1810. The first flat portion 1816 and the second flat portion 1818 of the first support layer 1810 are constructed without the slit 1814. Multiple support pieces 1812 of the flexible section 1803 are arranged to be connected to one another. As another example, the multiple support pieces 1812 of the flexible section 1803 may be separated from each other.

[0129] According to one embodiment, a first skin layer 1822 is positioned above the first support layer 1810 (for example, in the y-axis direction) with respect to the folding axis (for example, the A-axis), and the upper side (for example, in the y-axis direction) of the multiple slits 1814 of the flexible portion 1803 is formed in a closed configuration. Multiple support pieces 1812 are connected by the first skin layer 1822. According to one embodiment, a second skin layer 1832 is positioned below the first support layer 1810 (for example, in the -y axis direction) with respect to the folding axis (for example, the A axis), and the lower side (for example, in the -y axis direction) of the multiple slits 1814 of the flexible portion 1803 is formed in a closed configuration. Multiple support pieces 1812 are connected by a second skin layer 1832.

[0130] In another embodiment, the first skin layer 1822 and the second skin layer 1832 include slits in a direction perpendicular to the plurality of slits 1814. According to one embodiment, the first support layer 1810, the second support layer 1820, and the third support layer 1830 of the flexible plate 1800 include carbon fiber reinforced plastic (CFRP). In one embodiment, the first support layer 1810, the second support layer 1820, and the third support layer 1830 of the flexible plate 1800 are oriented in the same direction 1020 as the first direction (e.g., the folding axis 1001) (e.g., the A axis) (e.g., 0-degree orientation).

[0131] In one embodiment, the first support layer 1810, the second support layer 1820, and the third support layer 1830 of the flexible plate 1800 are oriented in the same direction 1020 as the first direction (e.g., the folding axis 1001) (e.g., the A axis) (e.g., 0-degree orientation) and in the direction 1010 perpendicular to the second direction (e.g., the folding axis 1001) (e.g., the A axis) (e.g., 90-degree orientation). In one embodiment, the flexible plate 1800 has a first skin layer 1822 positioned on the upper part of the flexible portion 1803 and a second skin layer 1832 positioned on the lower part of the flexible portion 1803, forming the upper and lower sides of the flexible portion 1803 flat. This reduces the step difference between the upper and lower surfaces of the flexible plate 1800, improves surface quality, increases shear strength, and ensures flexibility.

[0132] Figure 19 shows a flexible plate according to an embodiment of the present invention. Referring to Figure 19, the electronic device (e.g., the electronic device 100 in Figure 5a) includes flexible plates 1900 (e.g., flexible plate 900 in Figure 9, flexible plate 1100 in Figure 11, and flexible plate 1200 in Figure 12).

[0133] The flexible plate 1900 is formed from multiple layers (1910, 1920, 1930). The flexible plate 1900 has multiple layers (1910, 1920, 1930), including a first support layer 1910, a second support layer 1920, and a third support layer 1930. In one embodiment, the second support layer 1920 is located at the uppermost end, and the first support layer 1910 is located below the second support layer 1920. The third support layer 1930 is located below the first support layer 1910.

[0134] According to one embodiment, the flexible plate 1900 includes a first planar portion 1901 facing a first region (e.g., the first region (h1) in Figure 4b) of the display (e.g., the display 400 in Figure 4b), a second planar portion 1902 facing a second region (e.g., the second region (h2) in Figure 4b) of the display 400, and a flexible portion 1903 facing a third region (e.g., the third region (h3) in Figure 4b) of the display 400. According to one embodiment, the flexible plate 1900 is folded and unfolded together with the display panel (e.g., the display panel 430 in Figure 4b) based on a folding axis (e.g., axis A) via at least a portion of the flexible portion 1903.

[0135] According to one embodiment, at least a portion of the flexible portion 1903 is positioned to support the back of the display panel (e.g., the display panel 430 in Figure 4b) when bending occurs in the display (e.g., the third region (h3) of the display 400 in Figure 4b). According to one embodiment, the flexible portion 1903 of the flexible plate 1900 includes a plurality of slits 1914 and a plurality of support pieces 1912 formed at regular or irregular intervals. The first flat portion 1916 and the second flat portion 1918 of the first support layer 1910 are constructed without the slit 1914.

[0136] In one embodiment, the multiple slits 1914 are formed in the first support layer 1910, the second support layer 1920, and the third support layer 1930 of the flexible portion 1903, and the multiple slits 1914 are filled with resin. Multiple support pieces 1912 are connected by resin filling multiple slits 1914. Furthermore, the resin filling the multiple slits 1914 seals the upper and lower sides of the flexible portion 1903, forming it flat. This reduces the step difference between the upper and lower surfaces of the flexible plate 1900, improves surface quality, increases shear strength, and ensures flexibility.

[0137] Figure 20 shows the Velcro pattern depending on the position of the flexible plate according to an embodiment of the present invention, and Figure 21 shows the folded state (e.g., closed state) of the electronic device according to an embodiment of the present invention. Referring to Figures 20 and 21, the electronic device 2000 (for example, the electronic device 100 in Figure 5a) includes flexible plates 2010 (for example, flexible plate 500 in Figure 5a, flexible plate 1310 in Figure 13a). The flexible plate 2010 is formed from a single layer or multiple layers (for example, multiple layers in Figure 11 (1110, 1120), multiple layers in Figure 12 (1210, 1220, 1230, 1240)).

[0138] According to one embodiment, the flexible plate 2010 includes a first planar portion (e.g., the first planar portion 1311a in Figure 13a) facing a first region (e.g., the first region (h1) in Figure 4b) of the display (e.g., the display 400 in Figure 4b), a second planar portion (e.g., the second planar portion 1311b in Figure 13a) facing a second region (e.g., the second region (h2) in Figure 4b) of the display 400, and a flexible portion 2001 (e.g., the flexible portion 1311c in Figure 13a) facing a third region (e.g., the third region (h3) in Figure 4b) of the display 400. According to one embodiment, the flexible plate 2010 is folded and unfolded together with the display panel (e.g., the display panel 430 in Figure 4b) based on a folding axis (e.g., axis A in Figure 13a) via at least a portion of the flexible portion 2001.

[0139] According to one embodiment, at least a portion of the flexible portion 2001 is positioned to support the back of the display panel (e.g., the display panel 430 in Figure 4b) when bending occurs in the display (e.g., the third region (h3) of the display 400 in Figure 4b). According to one embodiment, the flexible portion 2001 of the flexible plate 2010 includes a plurality of slits 2011 formed at regular or irregular intervals, a plurality of support pieces 2013, and a plurality of Velcro patterns (2012, 2014, 2016) extending from the plurality of support pieces 2013. Multiple support pieces 2013 of the flexible section 2001 are arranged to be separated from each other by multiple slits 2011. Multiple support pieces 2013 are connected by multiple Velcro patterns (2012, 2014, 2016).

[0140] In one embodiment, the plurality of Velcro patterns (2012, 2014, 2016) include a plurality of first Velcro patterns 2012, a plurality of second Velcro patterns 2014, and a plurality of third Velcro patterns 2016. In one embodiment, a plurality of first Velcro patterns 2012 are arranged on the upper end portion 2010a of the flexible plate 2010. In one embodiment, a plurality of second Velcro patterns 2014 are arranged in the central part 2010b of the flexible plate 2010. In one embodiment, a plurality of third Velcro patterns 2016 are arranged on the lower end portion 2010c of the flexible plate 2010.

[0141] According to one embodiment, when the electronic device 2000 is in a folded state (e.g., closed state), a high tensile load may be applied to the multiple first Velcro patterns 2012 located at the upper end 2010a and the multiple third Velcro patterns 2016 located at the lower end 2010c. In one embodiment, to withstand the high tensile load applied when the electronic device 2000 is in a folded state (e.g., closed state), the multiple first Velcro patterns 2012 located at the upper end 2010a and the multiple third Velcro patterns 2016 located at the lower end 2010c are formed to be thicker than the multiple second Velcro patterns 2014 located at the central part 2010b.

[0142] Figure 22 shows a flexible plate for an electronic device according to an embodiment of the present invention. Referring to Figure 22, the electronic device 2200 (for example, the electronic device 100 in Figure 5a) includes flexible plates 2210 (for example, flexible plate 500 in Figure 5a, flexible plate 1310 in Figure 13a). The flexible plate 2210 is formed from a single layer or multiple layers (for example, multiple layers in Figure 11 (1110, 1120), multiple layers in Figure 12 (1210, 1220, 1230, 1240)).

[0143] According to one embodiment, the flexible plate 2210 includes a first planar portion (e.g., the first planar portion 1311a in Figure 13a) facing a first region (e.g., the first region (h1) in Figure 4b) of the display (e.g., the display 400 in Figure 4b), a second planar portion (e.g., the second planar portion 1311b in Figure 13a) facing a second region (e.g., the second region (h2) in Figure 4b) of the display 400, and a flexible portion 2201 (e.g., the flexible portion 1311c in Figure 13a) facing a third region (e.g., the third region (h3) in Figure 4b) of the display 400. According to one embodiment, the flexible plate 2210 is folded and unfolded together with the display panel (e.g., the display panel 430 in Figure 4b) based on a folding axis (e.g., axis A in Figure 13a) via at least a portion of the flexible portion 2201.

[0144] According to one embodiment, at least a portion of the flexible portion 2201 is positioned to support the back of the display panel (e.g., the display panel 430 in Figure 4b) when bending occurs in the display (e.g., the third region (h3) of the display 400 in Figure 4b). According to one embodiment, the flexible portion 2201 of the flexible plate 2210 includes a plurality of slits 2211 formed at constant or irregular intervals, a plurality of support pieces (2212, 2216), and a plurality of Velcro patterns (2214, 2218) extending from the plurality of support pieces (2212, 2216).

[0145] Multiple support pieces (2212, 2216) of the flexible section 2201 are arranged to be separated from each other by multiple slits 2211. Multiple support pieces (2212, 2216) are connected by multiple Velcro patterns (2214, 2218). In one embodiment, the plurality of support pieces (2212, 2216) include a plurality of first support pieces 2212 and a plurality of second support pieces 2216. The multiple first support pieces 2212 are formed such that their width narrows from the upper end 2210a of the flexible plate 2210 to the central part 2210b. The multiple second support pieces 2216 are formed such that their width narrows from the lower end 2210c of the flexible plate 2210 to the central part 2210b. In another embodiment, the plurality of first support pieces 2212 and the plurality of second support pieces 2216 may be formed such that their width gradually increases or decreases as they move left or right with respect to the folding axis.

[0146] In one embodiment, the plurality of Velcro patterns (2214, 2218) includes a plurality of first Velcro patterns 2214 and a plurality of second Velcro patterns 2218. In one embodiment, a plurality of first Velcro patterns 2214 are formed such that their length is extended by a plurality of first support pieces 2212. Multiple second Velcro patterns 2218 are formed such that their length is extended in multiple second support pieces 2216.

[0147] In one embodiment, the flexible plate 2210 has multiple first support pieces 2212 that are wider at the upper end 2210a and multiple second support pieces 2216 that are wider at the lower end 2210c, thereby enhancing durability against impacts applied to the upper and lower ends of the electronic device 2200 and increasing shear strength. Furthermore, flexibility is ensured, making it easy to fold and unfold the folding area.

[0148] Figure 23 shows a flexible plate according to an embodiment of the present invention. Referring to Figure 23, the tensile elongation and compression ratios can be adjusted according to the widths (w1) and w2 of the multiple support pieces (2311, 2321, 2331) of the flexible plates (2310, 2320, 2330) and the lengths (d1, d2) of the multiple Velcro patterns (2312, 2314, 2322, 2324, 2332, 2334).

[0149] In one embodiment, the width (w1) of the first support piece 2311 of the first flexible plate 2310 and the width (w1) of the second support piece 2321 of the second flexible plate 2320 are made the same. The first Velcro patterns (2312, 2314) of the first flexible plate 2310 are formed to have a first length (w1), and the second Velcro patterns (2322, 2324) of the second flexible plate 2320 are formed to have a second length (w2) that is longer than the first length (w1). In this way, by making the width (w1) of the first support piece 2311 and the second support piece 2321 the same, and making the length (w2) of the second Velcro pattern (2322, 2324) longer than the length (w1) of the first Velcro pattern (2312, 2314), the tensile elongation ratio can be increased.

[0150] In one embodiment, the third support piece 2331 of the third flexible plate 2330 is made wider (w2) than the width (w1) of the first support piece 2311 of the first flexible plate 2310. The first Velcro patterns (2312, 2314) of the first flexible plate 2310 are formed to have a first length (w1), and the third Velcro patterns (2332, 2334) of the third flexible plate 2320 are similarly formed to have a first length (d1). In this way, by making the lengths (d1) of the first Velcro pattern (2312, 2314) and the third Velcro pattern (2332, 2334) the same, and making the width (w2) of the third support piece 2331 wider than the width (w1) of the first support piece 2311, the tensile elongation rate can be reduced and the shear strength can be increased.

[0151] Figure 24 shows a Velcro pattern 2420 of a flexible plate 2400 according to an embodiment of the present invention. Referring to Figure 24, in the embodiment of the present invention, the flexible plate 2400 has flexible parts (for example, flexible part 1103 in Figure 11, flexible part 1311c in Figure 13a, and flexible part 1703 in Figure 17) that are positioned in the folding region of an electronic device (for example, electronic device 100 in Figure 5a).

[0152] According to one embodiment, the flexible portion of the flexible plate 2400 (for example, the flexible portion 1103 in Figure 11, the flexible portion 1311c in Figure 13a, and the flexible portion 1703 in Figure 17) includes a plurality of support pieces 2410 and a plurality of Velcro patterns 2420. In one embodiment, the plurality of Velcro patterns 2420 include a first portion 2422 whose length is extended on the sides of the plurality of support pieces 2410 and a second portion 2424 whose length is extended at the ends of the first portion 2422. The first portion 2422 of each of the multiple Velcro patterns 2420 is formed to have a first width, and the second portion 2424 is formed to have a second width that is greater than the first width. The first portion 2422 of the multiple Velcro patterns 2420 is formed in a bar shape, and the second portion 2424 is formed in an elliptical shape with a certain curvature.

[0153] Figure 25 shows the flexible portion of a flexible plate according to an embodiment of the present invention. Referring to Figure 25, in the folded state (e.g., closed state) of the electronic device (e.g., electronic device 100 in Figure 2), the flexible part 2500 (e.g., flexible part 703 in Figure 7, flexible part 903 in Figure 9) is in a compressed state 2501. When the electronic device (for example, the electronic device 100 in Figure 2) is in an open state (for example, an open state), the flexible part 2500 (for example, the flexible part 703 in Figure 7, the flexible part 903 in Figure 9) is in a tensile state 2502.

[0154] As an embodiment, the flexible portion 2500 (for example, the flexible portion 703 in FIG. 7, the flexible portion 903 in FIG. 9) includes a plurality of Velcro patterns 2510. For example, the plurality of Velcro patterns 2510 includes a plurality of support pieces 2520 and a plurality of slit patterns 2530 formed in the plurality of Velcro patterns 2510. For example, a plurality of adjacent support pieces 2520 are arranged on the same line in the x-axis direction (for example, the horizontal direction). A plurality of adjacent support pieces 2520 are inserted into the slit pattern 2530 and arranged to engage with each other in a lattice shape, and the plurality of Velcro patterns 2510 are connected to each other without detachment.

[0155] For example, according to the compression state 2501 or the tensile state 2502, the interval between the plurality of Velcro patterns 2510 of the flexible portion 2500 is maximally increased or decreased. Even if the interval between the plurality of Velcro patterns 2510 of the flexible portion 2500 is maximally extended or decreased, the support piece 2520 and the slit pattern 2530 are arranged to engage with each other, and the plurality of Velcro patterns 2510 are connected to each other without detachment.

[0156] FIG. 26 is a diagram showing a flexible portion of a flexible plate according to an embodiment of the present invention. Referring to FIG. 26, in the folding state (for example, the closed state) of the electronic device (for example, the electronic device 100 in FIG. 2), the flexible portion 2600 (for example, the flexible portion 703 in FIG. 7, the flexible portion 903 in FIG. 9) is in the compression state 2601. In the open state (for example, the open state) of the electronic device (for example, the electronic device 100 in FIG. 2), the flexible portion 2600 (for example, the flexible portion 703 in FIG. 7, the flexible portion 903 in FIG. 9) is in the tensile state 2602.

[0157] In one embodiment, the flexible portion 2600 (for example, the flexible portion 703 in Figure 7, the flexible portion 903 in Figure 9) includes a plurality of Velcro patterns 2610. For example, the multiple Velcro patterns 2610 include multiple support pieces 2620 and multiple slit patterns 2630 formed on the multiple Velcro patterns 2610. For example, multiple adjacent support pieces 2620 are located on different lines in the x-axis direction (e.g., horizontal direction) and are arranged in a zigzag shape. Adjacent support pieces 2620 are inserted into the slit pattern 2630 and arranged to engage with each other in a lattice shape, so that multiple Velcro patterns 2610 are connected to each other without detachment.

[0158] For example, depending on the compression state 2601 or the tension state 2602, the spacing between the multiple Velcro patterns 2610 of the flexible portion 2600 increases or decreases to the maximum. Even when the spacing between the multiple Velcro patterns 2610 in the flexible section is maximized or reduced, the multiple support pieces 2620 and the slit pattern 2630 are arranged to engage with each other, and the multiple Velcro patterns 2610 are connected to each other without detaching.

[0159] Figure 27 shows the flexible portion of a flexible plate according to an embodiment of the present invention. Referring to Figure 27, in the folded state (e.g., closed state) of the electronic device (e.g., electronic device 100 in Figure 2), the flexible part 2700 (e.g., flexible part 703 in Figure 7, flexible part 903 in Figure 9) is in a compressed state 2701. When the electronic device (for example, the electronic device 100 in Figure 2) is in an open state (for example, an open state), the flexible part 2700 (for example, the flexible part 703 in Figure 7, the flexible part 903 in Figure 9) is in a tensile state 2702.

[0160] In one embodiment, the flexible portion 2700 (for example, the flexible portion 703 in Figure 7, the flexible portion 903 in Figure 9) includes a plurality of Velcro patterns 2710. For example, a plurality of Velcro patterns 2710 includes a plurality of support pieces 2720 and a plurality of slit patterns 2730 formed on the plurality of Velcro patterns 2710. For example, multiple support pieces 2720 are formed in a raised dumbbell shape, and multiple slit patterns 2730 are formed in an intaglio dumbbell shape. For example, multiple adjacent support pieces 2720 are arranged on the same line in the x-axis direction (e.g., horizontal direction). Adjacent support pieces 2720 are inserted into the slit pattern 2730 and arranged to engage with each other in a lattice shape, so that multiple Velcro patterns 2710 are connected to each other without detachment.

[0161] For example, depending on the compression state 2701 or the tension state 2702, the spacing between the multiple Velcro patterns 2710 of the flexible portion 2700 increases or decreases to the maximum. Even when the spacing between the multiple Velcro patterns 2710 in the flexible section is maximized or reduced, the multiple support pieces 2720 and the slit pattern 2730 are arranged to engage with each other, and the multiple Velcro patterns 2710 are connected to each other without detaching.

[0162] Figure 28 shows the flexible portion of a flexible plate according to an embodiment of the present invention. Referring to Figure 28, in the folded state (e.g., closed state) of the electronic device (e.g., electronic device 100 in Figure 2), the flexible part 2800 (e.g., flexible part 703 in Figure 7, flexible part 903 in Figure 9) is in a compressed state 2801. When an electronic device (for example, electronic device 100 in Figure 2) is in an open state (for example, an open state), the flexible part 2800 (for example, flexible part 703 in Figure 7, flexible part 903 in Figure 9) is in a tensile state 2802.

[0163] In one embodiment, the flexible portion 2800 (for example, the flexible portion 703 in Figure 7, the flexible portion 903 in Figure 9) includes a plurality of Velcro patterns 2810. For example, the multiple Velcro patterns 2810 include multiple support pieces 2820 and multiple slit patterns 2830 formed on the multiple Velcro patterns 2810. For example, multiple support pieces 2820 are formed in a raised dumbbell shape, and multiple slit patterns 2830 are formed in an intaglio dumbbell shape. For example, multiple adjacent support pieces 2820 are located on different lines in the x-axis direction (e.g., horizontal direction) and are arranged in a zigzag shape. Adjacent support pieces 2820 are inserted into the slit pattern 2830 and arranged to engage with each other in a lattice shape, so that multiple Velcro patterns 2810 are connected to each other without detachment.

[0164] For example, depending on the compression state 2801 or the tension state 2802, the spacing between the multiple Velcro patterns 2810 of the flexible portion 2800 increases or decreases to the maximum. Even when the spacing between the multiple Velcro patterns 2810 in the flexible section is maximized or reduced, the multiple support pieces 2820 and the slit pattern 2830 are arranged to engage with each other, and the multiple Velcro patterns 2810 are connected to each other without separating.

[0165] Figure 29 shows the flexible portion of a flexible plate according to an embodiment of the present invention. Referring to Figure 29, in the folded state (e.g., closed state) of the electronic device (e.g., electronic device 100 in Figure 2), the flexible part 2900 (e.g., flexible part 703 in Figure 7, flexible part 903 in Figure 9) is in a compressed state 2901. When the electronic device (for example, the electronic device 100 in Figure 2) is in an open state (for example, an open state), the flexible part 2900 (for example, the flexible part 703 in Figure 7, the flexible part 903 in Figure 9) is in a tensile state 2902.

[0166] As an embodiment, the flexible part 2900 (for example, the flexible part 703 in FIG. 7, the flexible part 933 in FIG. 9) includes a plurality of Velcro patterns 2910. For example, the plurality of Velcro patterns 2910 include a plurality of support pieces 2920 and a plurality of slit patterns 2930 formed in the plurality of Velcro patterns 2910. For example, the plurality of support pieces 2920 are formed in a male wedge shape, and the plurality of slit patterns 2930 are formed in a female wedge shape. For example, a plurality of adjacent support pieces 2920 are arranged on the same line in the x-axis direction (for example, the horizontal direction). Adjacent support pieces 2920 are inserted into the slit pattern 2930 and arranged to engage with each other in a lattice shape, and the plurality of Velcro patterns 2910 are connected to each other without detachment.

[0167] For example, according to the compressed state 2901 or the tensile state 2902, the interval between the plurality of Velcro patterns 2910 of the flexible part 2900 is maximally increased or decreased. Even if the interval between the plurality of Velcro patterns 2910 of the flexible part extends or decreases maximally, the plurality of support pieces 2920 and the slit pattern 2930 are arranged to engage with each other, and the plurality of Velcro patterns 2910 are connected to each other without detachment.

[0168] FIG. 30 is a diagram showing a flexible part of a flexible plate according to an embodiment of the present invention. Referring to FIG. 30, in the folding state (for example, the closed state) of the electronic device (for example, the electronic device 100 in FIG. 2), the flexible part 3000 (for example, the flexible part 703 in FIG. 7, the flexible part 903 in FIG. 9) is in the compressed state 3001. In the open state (for example, the open state) of the electronic device (for example, the electronic device 100 in FIG. 2), the flexible part 3000 (for example, the flexible part 703 in FIG. 7, the flexible part 903 in FIG. 9) is in the tensile state 3002. In one embodiment, the flexible portion 3000 (for example, the flexible portion 703 in Figure 7, the flexible portion 903 in Figure 9) includes a plurality of Velcro patterns 3010. For example, the multiple Velcro patterns 3010 include multiple support pieces 3020 and multiple slit patterns 3030 formed on the multiple Velcro patterns 3010. For example, multiple support pieces 3020 are formed in a raised wedge shape, and multiple slit patterns 3030 are formed in an intaglio wedge shape. For example, multiple adjacent support pieces 3020 are located on different lines in the x-axis direction (e.g., horizontal direction) and are arranged in a zigzag shape. Adjacent support pieces 3020 are inserted into the slit pattern 3030 and arranged to engage with each other in a lattice shape, so that multiple Velcro patterns 3010 are connected to each other without detachment.

[0170] For example, depending on the compression state 3001 or the tension state 3002, the spacing between the multiple Velcro patterns 3010 of the flexible part 3000 is increased or decreased to the maximum. Even when the spacing between the multiple Velcro patterns 3010 in the flexible section is maximized or reduced, the multiple support pieces 3020 and the slit pattern 3030 are arranged to engage with each other, and the multiple Velcro patterns 3010 are connected to each other without separating.

[0171] Figure 31 shows the flexible portion of a flexible plate according to an embodiment of the present invention. Referring to Figure 31, in the folded state (e.g., closed state) of the electronic device (e.g., electronic device 100 in Figure 2), the flexible part 3100 (e.g., flexible part 703 in Figure 7, flexible part 903 in Figure 9) is in a compressed state 3101. When the electronic device (for example, the electronic device 100 in Figure 2) is in an open state (for example, an open state), the flexible part 3100 (for example, the flexible part 703 in Figure 7, the flexible part 903 in Figure 9) is in a tensile state 3102.

[0172] In one embodiment, the flexible portion 3100 (for example, the flexible portion 703 in Figure 7, the flexible portion 903 in Figure 9) includes a plurality of Velcro patterns 3110. For example, the multiple Velcro patterns 3110 include multiple support pieces 3120 and multiple slit patterns 3130 formed on the multiple Velcro patterns 3110. For example, multiple support pieces 3120 are formed in an embossed staple-like (eye-shaped) form, and multiple slit patterns 3130 are formed in an intagliod staple-like (eye-shaped) form. For example, multiple adjacent support pieces 3120 are arranged on the same line in the x-axis direction (e.g., horizontal direction). Adjacent support pieces 3120 are inserted into the slit pattern 3130 and arranged to engage with each other in a lattice shape, so that multiple Velcro patterns 3110 are connected to each other without coming apart.

[0173] For example, depending on the compression state 3101 or the tension state 3102, the spacing between the multiple Velcro patterns 3110 of the flexible part 3100 increases or decreases to the maximum. Even when the spacing between the multiple Velcro patterns 3110 in the flexible section is maximized or reduced, the multiple support pieces 3120 and the slit pattern 3130 are arranged to engage with each other, and the multiple Velcro patterns 3110 are connected to each other without separating.

Referring to Figure 32, in the folded state (e.g., closed state) of the electronic device (e.g., electronic device 100 in Figure 2), the flexible part 3200 (e.g., flexible part 703 in Figure 7, flexible part 903 in Figure 9) is in a compressed state 3201. When an electronic device (for example, electronic device 100 in Figure 2) is in an open state (for example, an open state), the flexible part 3200 (for example, flexible part 703 in Figure 7, flexible part 903 in Figure 9) is in a stretched state 3202.

[0175] In one embodiment, the flexible portion 3200 (for example, the flexible portion 703 in Figure 7, the flexible portion 903 in Figure 9) includes a plurality of Velcro patterns 3210. For example, a plurality of Velcro patterns 3210 include a plurality of support pieces 3220 and a plurality of slit patterns 3230 formed on the plurality of Velcro patterns 3210. For example, multiple support pieces 3220 are formed in a raised wedge shape, and multiple slit patterns 3230 are formed in an intaglio wedge shape. For example, multiple adjacent support pieces 3220 are located on different lines in the x-axis direction (e.g., horizontal direction) and are arranged in a zigzag shape. Adjacent support pieces 3220 are inserted into the slit pattern 3230 and arranged to engage with each other in a lattice shape, so that multiple Velcro patterns 3210 are connected to each other without detachment.

[0176] For example, depending on the compression state 3201 or the tension state 3202, the spacing between the multiple Velcro patterns 3210 of the flexible portion 3200 increases or decreases to the maximum. Even when the spacing between the multiple Velcro patterns 3210 of the flexible portion 3200 is maximized or reduced, the multiple support pieces 3220 and the slit pattern 3230 are arranged to engage with each other, and the multiple Velcro patterns 3210 are connected to each other without detaching.

For example, the slit 3310 is formed in a bar shape.

[0179] In one embodiment, the flexible portion 3300 of a flexible plate (for example, the conductive plate 700 in Figure 7) is arranged such that a plurality of support pieces 3320 having a certain width are spaced apart via slits 3310 having a certain interval between them. The first planar portion (for example, the first planar portion 701 in Figure 7) of the flexible plate (for example, the conductive plate 700 in Figure 7) is composed only of the first support portion (for example, the first planar portion 701 in Figure 7) without the slit 3310, and the second planar portion (for example, the second planar portion 702 in Figure 7) is composed only of the second support portion (for example, the second support portion 720 in Figure 7) without the slit 3310.

[0180] According to one embodiment, the multiple slits 3310 of the flexible portion 3300 are formed in a manner in which the upper side (e.g., in the y-axis direction) and the lower side (e.g., in the -y-axis direction) are open based on the folding axis (e.g., axis A in Figure 7). According to one embodiment, the multiple slits 3310 of the flexible portion 3300 are formed to penetrate from the upper surface 3311 to the lower surface 3312 of the flexible portion 3300. The multiple slits 3310 of the flexible portion 3300 are formed to have a constant width from the upper surface 3311 to the lower surface 3312.

[0181] According to one embodiment, a plurality of support pieces 3320 are separated at regular intervals by a plurality of slits 3310. The multiple support pieces 3320, separated by the multiple slits 3310, remain connected to one another via conductive elastic members (for example, the conductive elastic member 460 in Figure 4b). Furthermore, the flexible portion 3300 is provided with flexibility via a plurality of support pieces 3320 connected via conductive elastic members (for example, the conductive elastic member 460 in Figure 4b).

[0182] In one embodiment, the number of slits 3310 in the flexible portion 3300 can be reduced from n to (1 / 2)n, and the width of the slits 3310 can be narrowed to improve the surface quality of the portion in contact with the flexible portion 3300 and the display (for example, the display 400 in Figure 4b).

[0183] Figure 34 shows the flexible portion of a flexible plate according to an embodiment of the present invention. Referring to Figure 34, a flexible plate according to an embodiment of the present invention (for example, the conductive plate 700 in Figure 7) includes a first planar portion (for example, the first planar portion 701 in Figure 7) that supports a first region (for example, the first region (h1) in Figure 4b) of a display (for example, the display 400 in Figure 4b), a second planar portion (for example, the second planar portion 702 in Figure 7) that supports a second region (for example, the second region (h2) in Figure 4b) of the display (for example, the display 400 in Figure 4b), and a flexible portion 3400 (for example, the flexible portion 703 in Figure 7) that supports a third region (for example, the third region (h3) in Figure 4b) of the display (for example, the display 400 in Figure 4b).

Furthermore, the flexible portion 3400 is provided with flexibility via a plurality of support pieces 3420 connected via conductive elastic members (for example, the conductive elastic member 460 in Figure 4b). Multiple slits 3410 in the flexible portion 3400 are formed such that their width increases from the upper surface 3411 to the lower surface 3412, thereby further improving the flexibility of the flexible portion 3400.

[0188] In one embodiment, the number of slits 3410 in the flexible portion 3400 is reduced from n to (1 / 2)n, and the slits 3410 in the flexible portion 3400 are formed such that their width narrows from the lower surface 3412 towards the upper surface 3411, thereby improving the surface quality of the portion in contact with the flexible portion 3400 and the display (for example, the display 400 in Figure 4b).

[0195] In one embodiment, the planar portion 3810 includes a first member 3811 (for example, a first carbon fiber) and a second member 3812 (a second carbon fiber) as rigid regions. For example, the first member 3811 (e.g., first carbon fiber) and the second member 3812 (second carbon fiber) are formed in a twisted manner. For example, the first member 3811 (e.g., the first carbon fiber) and the second member 3812 (the second carbon fiber) may have different stretching directions. For example, the first member 3811 (e.g., the first carbon fiber) and the second member 3812 (the second carbon fiber) may be arranged so that their stretching directions are perpendicular to each other.

[0196] For example, the fiber direction 3811a of the first member 3811 (e.g., first carbon fiber) of the planar portion 3810 is formed to extend in the x-axis direction (e.g., the transverse direction in Figure 38). The fiber direction 3812a of the second member 3812 (second carbon fiber) of the planar portion 3810 is formed to extend in the y-axis direction (for example, the longitudinal direction in Figure 38).

[0200] In one embodiment, the flat portion 3910 includes a first member 3911 (for example, a first resin) and a second member 3912 (a second resin) as rigid regions. For example, the first member 3911 (e.g., first resin) and the second member 3912 (second resin) are formed by twisting. For example, the first member 3911 of the flat portion 3910 contains a hard resin. For example, the first member 3911 (e.g., the first resin) and the second member 3912 (the second resin) may have different stretching directions. For example, the first member 3911 (e.g., the first resin) and the second member 3912 (the second resin) may be arranged so that their stretching directions are perpendicular to each other. For example, the first member 3911 (e.g., first resin) of the planar portion 3910 may be formed to extend in the lateral direction (e.g., in the x-axis direction). The second member 3912 (second resin) of the planar portion 3910 may be formed to extend in the vertical direction (for example, in the y-axis direction).
