Description

electronic devices

[0001] Embodiments of the present disclosure relate to foldable electronic devices.

[0002] As the functional gap between manufacturers narrows significantly, electronic devices are becoming increasingly slimmer to meet consumer purchasing demands. This trend is driven by increased rigidity, enhanced design, and differentiated functional elements. These devices are moving beyond the standard rectangular form factor and evolving into diverse shapes. For example, electronic devices may be designed to be portable and, when in use, feature a transformable structure that allows for large-screen displays.

[0003] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art in connection with the present disclosure.

[0004] As foldable electronic devices continue to be released as part of the electronic device market, a support plate for a foldable display may include a bendable portion. The bendable portion of the support plate may be configured to be foldable by having multiple openings spaced apart from each other.

[0005] A foldable type electronic device may include a support plate including at least one signal line, which is a path for transmitting a signal, and the signal line of the support plate may be arranged to cross the bendable portion. For example, the signal line may be arranged to bypass a plurality of openings arranged in the bendable portion.

[0006] However, due to the narrow width between the multiple openings, the design of the signal line width may be limited when the signal line crosses the bendable section. If the design of the line width is limited, the signal line width inevitably becomes narrow, which may cause a degradation in the performance of the signal line. For example, the signal line may cause signal loss when transmitting a high-speed signal (e.g., a high-speed signal) due to the narrow line width in the bendable section.

[0007] Embodiments of the present disclosure can provide a support plate including a structure of a signal line capable of reducing signal loss and an electronic device including the same.

[0008] The technical problems to be achieved in the present disclosure are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

A differential signal line (630) is disposed and includes a first signal line (631) and a second signal line (632), wherein in the first planar portion (551) and the second planar portion (552), the first signal line (631) and the second signal line (632) are disposed in parallel with a specified interval, and in the bendable portion (553), the first signal line (631) extends along a first curved path that bypasses the plurality of openings (5531), and in the bendable portion (553), the second signal line (632) extends along a second curved path that overlaps at least a portion of the first curved path, wherein the second signal line (632) can be disposed in a different layer from the first signal line (631) in the second curved path.

These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0056] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)).

[0096] FIG. 5 is an exploded perspective view illustrating a laminated structure of a flexible display (500) according to various embodiments of the present invention.

[0097] The flexible display (500) of FIG. 5 may be at least partially similar to the first display (330) of FIG. 2A or may further include other embodiments of the display.

[0098] Referring to FIG. 5, a flexible display (500) (e.g., a first display (330) of FIG. 2A) may include a window (510) (e.g., a polyimide (PI) film), a polarizer (POL) (520) (e.g., a polarizing film) sequentially disposed on a back surface of the window (510), a display panel (530), a polymer member (540), and / or a support plate (550).

[0100] In one embodiment, the polymer member (540) may be applied with a dark color (e.g., black) to help display the background when the display is off. In one embodiment, the polymer member (540) may act as a cushion to absorb external shocks from the electronic device and prevent damage to the flexible display (500).

[0101] According to one embodiment, the support plate (550) serves to support the display panel (530) and may include glass fiber reinforced plastic (GFRP) or carbon fiber reinforced plastic (CFRP). The support plate (550) includes a multi-layer structure including a plurality of layers, and a high-speed signal line (e.g., a differential signal line (630) of FIG. 15), a ground line (e.g., a ground line (640) of FIG. 16), and / or an RF signal line (e.g., an RF signal line (650) of FIG. 22) may be arranged on at least some of the layers. The high-speed signal lines (e.g., differential signal lines), ground lines, and RF signal lines of the support plate (550) can serve to electrically connect some components (e.g., the first substrate (361) of FIG. 4) placed in the first housing (the first housing (310) of FIG. 2A) and some components (e.g., the second substrate (362) of FIG. 4) placed in the second housing (the second housing (320) of FIG. 2A), and accordingly, the electronic device (e.g., the electronic device (101) of FIG. 2A) can reduce or omit the PCB or FPCB for transmitting signals.

[0102] In one embodiment, the support plate (550) may further include a metal sheet to help reinforce the rigidity of the electronic device (101), shield ambient noise, and disperse heat emitted from a surrounding heat dissipating component (e.g., the processor (120) of FIG. 1). In one embodiment, the support plate (550) may include at least one metal sheet of Cu, Al, SUS, or CLAD (e.g., a laminated member in which SUS and Al are alternately arranged).

[0103] Figure 6 is an enlarged plan view of a portion of the support plate illustrated in Figure 5.

[0104] The support plate (550) of FIG. 6 may be at least partially similar to the support plate (550) of FIG. 5 or may further include other embodiments of the support plate (550).

[0105] Referring to FIG. 6, a support plate (550) according to one embodiment may include a first planar portion (551) facing a first housing (e.g., a first housing (310) of FIG. 2a), a second planar portion (552) facing a second housing (e.g., a second housing (320) of FIG. 2a), and a bendable portion (553) formed to be bendable through a plurality of openings (5531) arranged to face a hinge structure (e.g., a hinge structure (340) of FIG. 2b) between the first planar portion (551) and the second planar portion (552) and arranged at intervals.

[0106] According to one embodiment, the bendable portion (553) may include a plurality of openings (5531) spaced apart from each other. According to one embodiment, the openings (5531) may refer to areas from which a metal material is removed. For example, the support plate (550) may include a multi-layer structure including a plurality of layers, and at least some layers among the plurality of layers may include metal members for high-speed signal lines (e.g., the differential signal line (630) of FIG. 15), ground lines (e.g., the ground line (640) of FIG. 16), and / or RF signal lines (e.g., the RF signal line (650) of FIG. 22). The multi-layer structure of the support plate (550) will be described in detail below with reference to FIGS. 18A, 18B, 19A, 19B, 20A, 20B, 21A, 21B, and 21C.

[0107] In the present disclosure, the openings (5531) of the support plate (550) may mean an area in which a metal member is not placed in the bendable portion (553).

[0108] According to one embodiment, the plurality of openings (5531) may be formed along a first direction (e.g., length direction) (e.g., y-axis direction) of the bendable portion (553) and a second direction (e.g., width direction) perpendicular to the first direction (e.g., x-axis direction) (e.g., x-axis direction). According to one embodiment, the plurality of openings (5531) may be formed in an elliptical shape of a long hole along the first direction (e.g., y-axis direction) of the bendable portion (5533). According to one embodiment, the plurality of openings (5531) may be arranged in an alternating and coincident manner along the second direction (e.g., x-axis direction) of the bendable portion (5533). According to one embodiment, the plurality of openings (5531) may be arranged at regular or irregular intervals along the first direction (e.g., y-axis direction) and / or the second direction (e.g., x-axis direction). According to one embodiment, the plurality of openings (5531) may be formed in the same shape or different shapes. According to one embodiment, the bendable portion (553) may exhibit elasticity to return to its original state after being deformed through the lattice structure formed by the plurality of openings (5531), and this elasticity may help provide flexibility to the bendable portion.

[0109] According to one embodiment, the flexibility of the bendable portion (553) may be determined by the spacing, shape, or arrangement density between the plurality of openings (5531). For example, the flexibility of the bendable portion (553) may be determined by the length (l) of one opening (e.g., a unit opening). According to one embodiment, the flexibility of the bendable portion (553) may be determined by the width (w) of one opening. According to one embodiment, the flexibility of the bendable portion (553) may be determined by the first spacing (d1) between the openings (5531) formed in the second direction (e.g., the x-axis direction). According to one embodiment, the flexibility of the bendable portion (553) may be determined by the second spacing (d2) between the openings (5531) formed in the first direction (e.g., the y-axis direction).

[0110] The support plate (550) of FIG. 7 may be at least partially similar to the support plates (550) of FIGS. 5 and 6 or may further include other embodiments of the support plate (550).

[0111] Referring to FIG. 7, a support plate (550) according to one embodiment (e.g., the support plate (550) of FIG. 6) may include a high-speed signal line (e.g., a differential signal line (630)) and an RF signal line (650). Although not shown, the support plate (550) may further include a ground line to serve as a reference plane. The ground line may extend to overlap at least a portion of the differential signal line (630). In the present disclosure, the ground line will be described in detail below with reference to FIGS. 16, 18A, 18B, 19A, 19B, 20A, 20B, 21A, 21B, and 21C.

[0112] According to one embodiment, the differential signal line (630), the ground line, and the RF signal line (650) can be arranged to extend from at least a portion of the first planar portion (551) across the bendable portion (553) to at least a portion of the second planar portion (552).

[0113] According to one embodiment, the differential signal line (630), the ground line, and the RF signal line (650) may serve to electrically connect a first component (610) (e.g., a first substrate (361) of FIG. 4) disposed in a first housing (a first housing (310) of FIG. 2A) and a second component (620) (e.g., a second substrate (362) of FIG. 4) disposed in a second housing (a second housing (320) of FIG. 2A), and accordingly, an electronic device (e.g., an electronic device (101) of FIG. 2A) may reduce or omit a PCB or FPCB for transmitting a signal.

[0114] According to one embodiment, the differential signal line (630) may be a pair of signal lines, including a first signal line (631) and a second signal line (632).

In one embodiment, the multi-foldable electronic device (700) may include a flexible display (740) (e.g., a first display) that is arranged to be supported by a first housing (710), a second housing (720), and a third housing (730). In one embodiment, the multi-foldable electronic device (700) may include a sub-display (750) (e.g., a second display) that is arranged through the third housing (730). In this document, the surface on which the flexible display (740) is arranged may be defined as the front surface of the multi-foldable electronic device (700), and the surface opposite the front surface may be defined as the back surface of the multi-foldable electronic device (700). In one embodiment, the surface surrounding the space between the front surface and the back surface may be defined as the side surface of the electronic device (700).In this document, a state in which the first housing (710), the second housing (720), and the third housing (730) of the multi-foldable electronic device (700) are fully unfolded may be defined as a 'first state' or a 'fully unfolded state', a state in which the first housing (710), the second housing (720), and the third housing (730) are fully folded with respect to each other may be defined as a 'second state' or a 'fully folded state', and a state in which only the first housing (710) and the second housing (720) are folded with respect to each other may be defined as a 'third state' or an 'intermediate state'.

[0119] According to one embodiment, the first housing (710) may include a first surface (711), a second surface (712) facing opposite to the first surface (711), and a first side member (713) surrounding a first space (7101) between the first surface (711) and the second surface (712).

In one embodiment, the second side member (723) may include a third side surface (7231), a fourth side surface (7232) extending in a direction perpendicular to the third side surface (7231), and a fifth side surface (7233) extending from the fourth side surface (7232) and being parallel to the third side surface (7231). In one embodiment, the second housing (720) may include a second rear cover (724) coupled with a second side member (723). In one embodiment, the sub-display (750) may be replaced to be disposed through at least a portion of the second rear cover (724) in the second housing (720). In some embodiments, the multi-foldable electronic device (700) may include an additional sub-display disposed through at least a portion of the second rear cover (724) in the second housing (720). In this case, when the first housing (710) and the second housing (720) are fully folded and the third housing (730) is partially folded (e.g., the third housing (730) is folded at an angle of about 90 degrees with respect to the first housing (710), the sub-display arranged on the fourth side (722) of the second housing (720) can be arranged to be visible from the outside. In one embodiment, the second space (7201) can be formed through the second rear cover (724) coupled with the second side member (723) on the fourth side (722).

[0121] In one embodiment, the third housing (730) may include a fifth side (731), a sixth side (732) facing opposite to the fifth side (731), and a third side member (733) surrounding a third space (7301) between the fifth side (731) and the sixth side (732).

In one embodiment, the seventh side (7332) may form one side (e.g., the left side) of the multi-foldable electronic device (700).

[0123] According to one embodiment, the multi-foldable electronic device (700) may be configured such that, in an unfolded state (e.g., a first state), the first housing (710), the second housing (720), and the third housing (730) are positioned side by side so that the first side (711), the third side (721), and the fifth side (731) face the same direction. In one embodiment, the multi-foldable electronic device (700) may be configured such that, in a folded state (e.g., a second state), the first housing (710), the second housing (720), and the third housing (730) are positioned in a sequentially stacked manner so that the first side (711) and the third side (721) face each other, and the fourth side (722) and the fifth side (731) face each other.

In one embodiment, the sub-display (750) may be positioned so as to be visible from the outside through at least a portion of the sixth side (732) in the unfolded and / or folded state.

[0124] According to various embodiments, the multi-foldable electronic device (700) may include at least one housing, including a first housing (710), a second housing (720), and a third housing (730), and the manner in which these (710, 720, 730) are foldably coupled to each other may be variously changed. For example, the manner in which the first housing (710), the second housing (720), and the third housing (730) are foldably coupled to each other is not limited to the examples of FIGS. 8A to 9C and may be variously changed. According to one embodiment, the first housing (710), the second housing (720), and the third housing (730) may have different sizes. In one embodiment, the first housing (710) may have a first width (HW1), the second housing (720) may have a second width (HW2) smaller than the first width (HW1), and the third housing (730) may have a third width (HW3) larger than the first width (HW1). For example, by defining these widths (HW1, HW2, HW3) of the housings (710, 720, 730), the multi-foldable electronic device (700) may be configured so that, when folded, none of the housings protrudes outward, thereby helping to improve an attractive appearance and portability. However, the present invention is not limited thereto, and at least two of the first, second, and third widths (HW1, HW2, HW3) may be configured to be the same.

[0125] According to one embodiment, the flexible display (740) may include a first region (740a) corresponding to at least a portion of the first housing (710), a second region (740b) extending from one side (e.g., a right side) of the first region (740a) and corresponding to at least a portion of the second housing (720), and a third region (740c) extending from the other side (e.g., a left side) of the first region (740a) and corresponding to at least a portion of the third housing (730). In one embodiment, the flexible display (740) may include a portion of a first region (740a) and a portion of a second region (740b), a fourth region (740d) that is flexible (e.g., a first folding region) corresponding to a first hinge assembly (HA1), and a fifth region (740e) that is flexible (e.g., a second folding region) corresponding to a second hinge assembly (HA2) and a portion of a first region (740a) and a portion of a third region (740c). In one embodiment, the region division of the flexible display (740) is merely an exemplary division by three housings (710, 720, 730) and two hinge assemblies (HA1, HA2), and the flexible display (740) may be displayed as a substantially seamless, single full screen. In one embodiment, the first region (740a) and the second region (740b) may have an overall symmetrical shape or a partially asymmetrical shape with respect to the fourth region (740d) and / or the first folding axis (F1). In one embodiment, the first region (740a) and the third region (740c) may have an overall symmetrical shape or a partially asymmetrical shape with respect to the fifth region (740e) and / or the second folding axis (F2). In one embodiment, the first folding width (BW1) of the fourth region (740d) may be smaller than the second folding width (BW2) of the fifth region (740e) in a direction perpendicular to the first folding axis (F1) (e.g., the x-axis direction). In some embodiments, the area of ​​the fourth region (740d) may be smaller than the area of ​​the fifth region (740e).This may be due to the fact that the first hinge assembly (HA1) connecting the first housing (710) and the second housing (720) and the second hinge assembly (HA2) connecting the first housing (710) and the third housing (730) are different from each other. For example, the size of at least one first hinge module (e.g., narrow hinge module) of the first hinge assembly (HA1) connecting the first housing (710) and the second housing (720) may be smaller than the size of at least one second hinge module (e.g., wide hinge module) of the second hinge assembly (HA2) connecting the first housing (710) and the third housing (730) and folding the flexible display (740) in a folded state.

Accordingly, features not described in FIG. 13 will be replaced with the description of the embodiment of FIG. 12.

[0161] According to one embodiment, in the support plate (550) according to one embodiment, the width of the first bendable portion (553) may be smaller than the width of the second bendable portion (555). Therefore, in one embodiment of FIG. 8b, in a direction perpendicular to the first folding axis (e.g., F1 of FIG. 8b) and the direction perpendicular to the x-axis of FIG. 8b, the first folding width (e.g., the first folding width (BW1) of FIG. 8b) corresponding to the first bendable portion (553) may be smaller than the second folding width (e.g., the second folding width (BW2) of FIG. 8b) corresponding to the second bendable portion (555).

[0162] Referring to FIG. 13, according to one embodiment, a differential signal line (630), a ground line (e.g., a ground line (640) of FIG. 16), and an RF signal line (650) may electrically connect a first component (610) (e.g., a first substrate) disposed in a third housing (a third housing (730) of FIG. 8A) and a third component (615) (e.g., a third substrate) disposed in the first housing (a first housing (710) of FIG. 8A). For example, at least some of the differential signal line (630), the ground line, and the RF signal line (650) may branch from the second plane portion (552) and be electrically connected to the third component (615).

[0163] Fig. 14 is a plan view illustrating a portion of a signal line of a support plate (550) according to a comparative example.

[0164] The support plate (550) of FIG. 14 may be at least partially similar to the support plates (550) of FIGS. 5, 6, and 7.

[0165] Referring to FIG. 14, a support plate (550) according to a comparative example may include a differential signal line (630) including a first signal line (631) and a second signal line (632), and an RF signal line (650). The support plate (550) may further include a ground line (not shown) to serve as a reference plane. The ground line may extend to overlap at least a portion of the differential signal line (630).

[0166] According to a comparative example, the first signal line (631) and the second signal line (632) can be spaced apart at a regularly designated interval in the first flat portion (551), the bendable portion (553), and the second flat portion (552).

[0167] According to a comparative example, the bending characteristic of the support plate (550) can be determined by a first spacing (d1) between adjacent openings (5531) defined in a first direction of the bendable portion (553) and / or a second spacing (d2) between adjacent openings (5531) defined in a second direction perpendicular to the first direction. According to a comparative example, the first spacing (d1) and the second spacing (d2) of the openings (5531) in the bendable portion (553) can be designed to be limited to values ​​specified or less in consideration of the bending characteristic of the bendable portion (553). Therefore, due to the narrow width between the plurality of openings (5531), when the differential signal line (630) and the RF signal line (650) cross the bendable portion (553), the design of the line width can be limited. If the design of the line width is limited, performance degradation of the differential signal line (630) and the RF signal line (650) may occur.

[0168] FIG. 15 is a plan view illustrating a portion of a differential signal line (630) of a support plate (550) according to one embodiment.

[0169] The support plate (550) of FIG. 15 may be at least partially similar to the support plates (550) of FIGS. 5, 6, 7, and 10 to 13, or may further include other embodiments of the support plates (550). The features of the support plate (550) described with reference to FIG. 15 may be applied to the support plates (550) of FIGS. 5, 6, 7, and 10 to 13.

[0170] Referring to FIG. 15, a support plate (550) according to one embodiment (e.g., the support plate (550) of FIG. 6) may include a differential signal line (630). The differential signal line (630) is arranged to extend from at least a portion of a first planar portion (551) across a bendable portion (553) (e.g., the first bendable portion (553) or the second bendable portion (555) of FIG. 10) to at least a portion of a second planar portion (552), and may include a first signal line (631) and a second signal line (632).

[0171] According to one embodiment, in the first plane portion (551) and the second plane portion (552), the first signal line (631) and the second signal line (632) can be arranged in parallel with a specified interval.

[0172] In one embodiment, in the bendable portion (553), the first signal line (631) may extend along a first curved path (810) that bypasses the plurality of openings (5531), and the second signal line (632) may extend across the bendable portion (553) via a different path than the first signal line (631). For example, in the bendable portion (553), the second signal line (632) may extend along a second curved path (820) that bypasses the plurality of openings (5531). Here, the second curved path (820) may be a different path than the first curved path (810).

[0173] In one embodiment, the first curved path (810) may include a plurality of U-shaped portions positioned around the plurality of openings (5531). In one embodiment, the second curved path (820) may include a plurality of U-shaped portions positioned around the plurality of openings (5531).

[0174] In one embodiment, the first curved path (810) and the second curved path (820) may be positioned adjacent to different portions of the plurality of openings (5531). For example, the first curved path (810) may be positioned adjacent to a first portion of the plurality of openings (5531), and the second curved path (820) may be positioned adjacent to a second portion of the plurality of openings (5531).

[0175] According to one embodiment, the plurality of U-shaped portions included in the first curved path (810) and the plurality of U-shaped portions included in the second curved path (820) may be arranged symmetrically with respect to each other. For example, the plurality of U-shaped portions included in the first curved path (810) and the plurality of U-shaped portions included in the second curved path (820) may form mirror images of each other.

[0176] According to one embodiment, the plurality of U-shaped portions included in the first curved path (810) and the plurality of U-shaped portions included in the second curved path (820) can bypass different portions of the plurality of openings (5531).

[0177] According to one embodiment, the widths of the first signal line (631) and the second signal line (632) may be maintained constant in the first planar portion (551) and the second planar portion (552), and may be varied in the flexible portion (553). For example, in the first planar portion (551) and the second planar portion (552), each of the first signal line (631) and the second signal line (632) may have a first width (W1). For example, in the flexible portion (553), each of the first signal line (631) and the second signal line (632) may have a first width (W1) or a second width (W2) greater than the first width (W1). For example, in the bendable portion (553), the second width (W2) of each of the first signal line (631) and the second signal line (632) may have a width that is about 50% or more of the spacing between adjacent openings (5531).

[0178] According to one embodiment, the width of each of the first signal line (631) and the second signal line (632) in the bendable portion (553) may vary depending on whether they are adjacent to each other. For example, in the bendable portion (553), the first signal line (631) and the second signal line (632) may have a relatively large second width (W2) in some paths where they are spaced apart from each other, and a relatively small first width (W1) in other paths where they are adjacent to each other.

[0179] According to one embodiment, the first curved path on which the first signal line (631) is arranged includes at least one first adjacent path (811) adjacent to the second signal line (632), wherein the first signal line (631) may have a first width (W1) in the first adjacent path (811). In the present disclosure, the first adjacent path (811) may mean a path in which the first signal line (631) approaches the second signal line (632) within a specified distance in the bendable portion (553). The first signal line (631) may have a second width (W2) in the first curved path (810) of the bendable portion (553) excluding the first adjacent path (811).

[0180] According to one embodiment, the second curved path (820) on which the second signal line (632) is arranged includes at least one second adjacent path (821) adjacent to the first signal line (631), wherein the second signal line (632) may have a first width (W1) in the second adjacent path (821). In the present disclosure, the first adjacent path (811) may mean a path in which the first signal line (631) approaches the second signal line (632) within a specified distance in the bendable portion (553). The second signal line (632) may have a second width (W2) in the second curved path (820) of the bendable portion (553) excluding the second adjacent path (821).

[0181] According to one embodiment, the support plate (550) includes a multi-layer structure including a plurality of layers, and the differential signal line (630) may be disposed on at least some of the plurality of layers. For example, the differential signal line (630) may be disposed on a first metal layer (e.g., the first metal layer (L1) of FIG. 18A) among the plurality of layers.

[0182] FIG. 16 is a plan view illustrating a portion of a ground line (640) of a support plate (550) according to one embodiment.

[0183] The support plate (550) of FIG. 16 may be at least partially similar to the support plates (550) of FIGS. 5, 6, and 7, or may further include other embodiments of the support plate (550). The features of the support plate (550) described with reference to FIG. 16 may be applied to the support plates (550) of FIGS. 5, 6, 7, and 10 to 13.

[0184] Referring to FIG. 16, a support plate (550) according to one embodiment (e.g., the support plate (550) of FIG. 6) may include a ground line (640) to serve as a reference plane. For example, the ground line (640) may extend to overlap at least a portion of the differential signal line (630) described with reference to FIG. 15.

[0185] According to one embodiment, the support plate (550) includes a multi-layer structure including a plurality of layers, and the ground line (640) may be disposed on at least some layers among the plurality of layers. For example, the ground line (640) may be disposed on a second metal layer (L2), a third metal layer (L3), or each of the second metal layer (L2) and the third metal layer (L3) among the plurality of layers. The second metal layer (L2) or the third metal layer (L3) may be a different layer from the first metal layer (L1) on which the differential signal line (630) described in the embodiment of FIG. 15 is disposed. For example, the second metal layer (L2) may be a layer disposed on top of the first metal layer (L1). For example, the third metal layer (L3) may be a layer disposed below the first metal layer (L1).

[0186] According to one embodiment, the ground line (640) is arranged to extend from at least a portion of the first planar portion (551) across the bendable portion (553) (e.g., the first bendable portion (553) or the second bendable portion (555) of FIG. 10) to at least a portion of the second planar portion (552), similar to the differential signal line (630) described in the embodiment of FIG. 15, and may overlap at least a portion of the differential signal line (630).

[0187] According to one embodiment, in the first planar portion (551) and the second planar portion (552), the ground line (640) may have a third width (W3).

[0188] According to one embodiment, in the bendable portion (553), the ground line (640) may have a third width (W3) or a fourth width (W4) that is smaller than the third width (W3).

[0189] According to one embodiment, the ground line (640) may have a third width (W3) in a path overlapping a first adjacent path (e.g., the first adjacent path (811) of FIG. 15) and a second adjacent path (e.g., the second adjacent path (821) of FIG. 15) in which the first signal line (631) and the second signal line (632) are adjacently arranged.

[0190] FIG. 17 is a plan view illustrating a portion of a differential signal line (630) of a support plate (550) according to another embodiment.

[0191] The support plate (550) of FIG. 17 may be at least partially similar to the support plates (550) of FIGS. 5, 6, and 7, or may further include other embodiments of the support plate (550). The features of the support plate (550) described with reference to FIG. 17 may be applied to the support plates (550) of FIGS. 5, 6, 7, and 10 to 13.

[0192] Referring to FIG. 17, a support plate (550) according to one embodiment (e.g., the support plate (550) of FIG. 6) has a difference in that, unlike the embodiment of FIG. 15, the differential signal line (630) includes a multi-layer structure. Hereinafter, only the embodiment of FIG. 17, which is different from the embodiment of FIG. 15, will be described. Accordingly, features not described in FIG. 17 will be replaced with the description of the embodiment of FIG. 15.

[0193] Referring to FIG. 17, a support plate (550) according to one embodiment is arranged to extend from at least a portion of a first planar portion (551) across a bendable portion (553) to at least a portion of a second planar portion (552), and may include at least one differential signal line (630) including a first signal line (631) and a second signal line (632).

[0194] According to one embodiment, the support plate (550) can arrange the first signal line (631) and the second signal line (632) in a horizontal manner in the first flat portion (551) and the second flat portion (552), and can arrange the first signal line (631) and the second signal line (632) in a vertical manner in the bendable portion (553).

[0195] According to one embodiment, in the first plane portion (551) and the second plane portion (552), the first signal line (631) and the second signal line (632) can be arranged in parallel with a specified interval.

[0196] According to one embodiment, in the bendable portion (553), the first signal line (631) may extend along a first curved path that bypasses the plurality of openings (5531), and the second signal line (632) may extend along a second curved path that overlaps the first curved path. For example, the second signal line (632) may extend along a second curved path that overlaps at least a portion of the first curved path, wherein the second signal line (632) may be disposed in a different layer from the first signal line (631) in the second curved path. In this way, the first signal line (631) may have a single-layer structure disposed in one metal layer, while the second signal line (632) may have a multi-layer structure disposed in a plurality of metal layers.

[0197] According to one embodiment, in the first planar portion (551) and the second planar portion (552), the first signal line (631) and the second signal line (632) may be arranged on the same layer. In the bendable portion (553), the first signal line (631) and the second signal line (632) may be arranged on different layers. For example, the second signal line (632) may be designed as a multi-layer structure including an upper line section arranged on the same layer as the first signal line (631) in the first planar portion (551) and the second planar portion (552), and a lower line section electrically connected to the upper line section through a via (910) and overlapping with at least a portion of the first signal line (631) in the bendable portion (553). In FIG. 17, the upper line section of the second signal line (632) is represented by a solid line, and the lower line section is represented by a dotted line.

[0198] According to one embodiment, the via (910) electrically connecting the upper line section and the lower line section of the second signal line (632) may include a first via (911) disposed at at least a portion of the boundary between the first planar portion (551) and the bendable portion (553), and a second via (912) disposed at at least a portion of the boundary between the second planar portion (552) and the bendable portion (553).

[0199] The support plate (550) according to one embodiment may further include a ground line (640) as described with reference to FIG. 16. For example, the ground line (640) may be arranged on a different layer from the differential signal line (630), may extend from at least a portion of the first planar portion (551) across the bendable portion (553) to at least a portion of the second planar portion (552), and may overlap at least a portion of the differential signal line (630).

[0200] The embodiment of FIG. 17 can increase the line width by having a multi-layer structure in which the first signal line (631) and the second signal line (632) extend while overlapping each other under design conditions in which the width between the openings (5531) in the bendable portion (553) (e.g., d1, d2 in FIG. 6) is limited. Accordingly, the embodiment of FIG. 17 can reduce performance degradation of the differential signal line (630) in the bendable portion (553).

[0201] FIGS. 18a, 18b, 19a, 19b, 20a, 20b, 21a, 21b, and 21c are cross-sectional views of various embodiments illustrating the laminated structure of the support plate (550) illustrated in FIG. 17. For example, FIGS. 18a, 18b, 19a, 19b, 20a, 20b, 21a, 21b, and 21c illustrate cross-sections of portions of the support plate (550) corresponding to the first planar portion (551) and the second planar portion (552) on the left, and cross-sections of other portions of the support plate (550) corresponding to the bendable portion (553) on the right.

[0202] The support plate (550) of FIGS. 18a, 18b, 19a, 19b, 20a, 20b, 21a, 21b, and 21c may be at least partially similar to the support plate (550) of FIGS. 5, 6, and 7, or may further include other embodiments of the support plate (550). The features of the support plate (550) described with reference to FIGS. 18a, 18b, 19a, 19b, 20a, 20b, 21a, 21b, and 21c may be applied to the support plates (550) of FIGS. 5, 6, 7, and 10-13.

[0203] Referring to FIG. 18a, a support plate (550) according to one embodiment (e.g., the support plate (550) of FIG. 6) includes a multi-layer structure including a plurality of layers, and a differential signal line (630) may be arranged in at least some of the plurality of layers.

[0204] According to one embodiment, the support plate (550) may include a first metal layer (L1), a second metal layer (L2) disposed on top of the first metal layer (L1), a third metal layer (L3) disposed under the first metal layer (L1), and / or a fourth metal layer (L4) disposed under the third metal layer (L3). For example, the support plate (550) may include a second metal layer (L2), and may further include a first metal layer (L1), a third metal layer (L3), and a fourth metal layer (L4) sequentially disposed under the second metal layer (L2). According to various embodiments, the support plate (550) may further include other metal layers in addition to the metal layers illustrated in FIGS. 18a, 18b, 19a, 19b, 20a, 20b, 21a, 21b, and 21c, and the present invention may not be limited thereto.

[0205] According to one embodiment, in the first planar portion (551) and the second planar portion (552), the differential signal line (630) may be arranged on the first metal layer (L1). For example, in the first planar portion (551) and the second planar portion (552), the first signal line (631) and the second signal line (632) may be arranged at a specified interval.

[0206] According to one embodiment, in the first planar portion (551) and the second planar portion (552), the differential signal line (630) may be configured in a stripline shape with a ground line (640) disposed on each of its upper and lower portions. For example, in the first planar portion (551) and the second planar portion (552), the ground line (640) may be disposed on each of the second metal layer (L2) and the third metal layer (L3), and these may be disposed to at least partially overlap the first signal line (631) and the second signal line (632).

[0207] According to one embodiment, in the bendable portion (553), the differential signal line (630) may be arranged in a multi-layer structure. For example, in the bendable portion (553), the first signal line (631) may be arranged in the first metal layer (L1), and in the bendable portion (553), the second signal line (632) may be arranged in the third metal layer (L3). Here, the second signal line (632) may be arranged in the third metal layer (L3), but may be arranged to overlap at least partially with the first signal line (631). The end of the second signal line (632) disposed on the third metal layer (L3) corresponding to the bendable portion (553) can be electrically connected to the second signal lines (632) disposed on the first metal layer (L1) corresponding to the first planar portion (551) and the second planar portion (552) through a via (e.g., via (910) of FIG. 17).

[0208] According to one embodiment, in the bendable portion (553), the differential signal line (630) may be implemented in a stripline form in which a ground line (640) is disposed on each of the upper and lower portions thereof. For example, in the bendable portion (553), the ground line (640) may be disposed on each of the second metal layer (L2) and the fourth metal layer (L4), and may be disposed so as to at least partially overlap the first signal line (631) and the second signal line (632). An end of the ground line (640) disposed on the fourth metal layer (L4) corresponding to the bendable portion (553) may be electrically connected to the ground lines (640) disposed on the third metal layer (L3) corresponding to the first planar portion (551) and the second planar portion (552) through a via (not shown).

[0209] The support plate (550) according to one embodiment illustrated in FIG. 18a can arrange the differential signal line (630) even under design conditions where the spacing between the openings (5531) (5513) is narrow by arranging the first signal line (631) and the second signal line (632) in different layers in the bendable portion (553).

[0210] Referring to FIG. 18b, a support plate (550) according to one embodiment (e.g., the support plate (550) of FIG. 6) may have a difference in that the laminated structure of the ground line (640) is changed, unlike the embodiment of FIG. 18a. Hereinafter, only the embodiment of FIG. 18b, which is different from the embodiment of FIG. 18a, will be described. Accordingly, features not described in FIG. 18b will be replaced with the description of the embodiment of FIG. 18a.

[0211] According to one embodiment, the stacked structure of the ground line (640) serving as a reference plane can be varied. For example, in the first planar portion (551) and the second planar portion (552), the ground line (640) is arranged in each of the second metal layer (L2) and the fourth metal layer (L4), and these can be arranged to at least partially overlap with the first signal line (631) and the second signal line (632).

[0212] The support plate (550) illustrated in FIG. 18b may include a design structure that fillcuts the ground in the third metal layer (L3). According to one embodiment, the ground line (640) of the fourth metal layer (L4) corresponding to the first planar portion (551) and the second planar portion (552) may extend to be continuously connected with the ground line (640) of the fourth metal layer (L4) corresponding to the bendable portion (553).

[0213] In the embodiment of FIG. 18b, compared to the embodiment of FIG. 18a, the distance between the differential signal line (630) and the ground line (640) disposed thereunder (e.g., the ground line (640) of the fourth metal layer (L4)) increases, so that the impedance may increase. Accordingly, the support plate (550) according to one embodiment may consider impedance matching, and the embodiment of FIG. 18b may lower the impedance by increasing the line width of the differential signal line (630) compared to the embodiment of FIG. 18a.

[0214] For reference, the impedance of the differential signal line (630) is inversely proportional to the line width of the differential signal line (630) and proportional to the spacing between the first signal line (631) and the second signal line (632).

[0215] Referring to FIG. 19A, a support plate (550) according to one embodiment (e.g., the support plate (550) of FIG. 6) may have a difference in that the line width of the differential signal line (630) is increased, unlike the embodiment of FIG. 18A. Hereinafter, only the embodiment of FIG. 19A that is different from the embodiment of FIG. 18A will be described. Accordingly, features not described in FIG. 19A will be replaced with the description of the embodiment of FIG. 18A.

[0216] According to one embodiment, the support plate (550) can increase the line width of the differential signal line (630) in the first planar portion (551) and the second planar portion (552) to reduce DCR (DC Resistance) and reduce signal loss. As the line width of the differential signal line (630) increases, impedance can decrease, and the support plate (550) can take this into consideration to reduce the area where the differential signal line (630) and the ground line (640) overlap each other. Similarly, the support plate (550) can be designed so that the differential signal line (630) and the ground line (640) do not completely overlap each other in the bendable portion (553), thereby enabling impedance matching, reducing DCR and reducing signal loss due to the increased line width. For example, in the flexible portion (553), the differential signal line (630) can be divided into a first region (6301) that overlaps with the ground line (640) and a second region (6302) that does not overlap with the ground line (640).

[0217] Referring to FIG. 19b, a support plate (550) according to one embodiment (e.g., the support plate (550) of FIG. 6) may have a difference in that the laminated structure of the ground line (640) is changed, unlike the embodiment of FIG. 19a. Hereinafter, only the embodiment of FIG. 19a that is different from the embodiment of FIG. 19a will be described. Accordingly, features not described in FIG. 19b will be replaced with the description of the embodiment of FIG. 19a.

[0218] According to one embodiment, the stacked structure of the ground line (640) serving as a reference plane can be varied. For example, in the first planar portion (551) and the second planar portion (552), the ground line (640) is arranged in each of the second metal layer (L2) and the fourth metal layer (L4), and these can be arranged to at least partially overlap with the first signal line (631) and the second signal line (632).

[0219] The support plate (550) illustrated in FIG. 19b may include a design structure that fillcuts the ground in the third metal layer (L3). According to one embodiment, the ground line (640) of the fourth metal layer (L4) corresponding to the first planar portion (551) and the second planar portion (552) may extend to be continuously connected with the ground line (640) of the fourth metal layer (L4) corresponding to the bendable portion (553).

[0220] Referring to FIG. 20A, a support plate (550) according to one embodiment (e.g., the support plate (550) of FIG. 6) may have a difference in that, unlike the embodiment of FIG. 18A, a differential signal line (630) is implemented in the form of a microstrip overlapping a single ground line (640).

Here, the second signal line (632) may be arranged in the third metal layer (L3), but may be arranged to overlap at least partially with the first signal line (631). The end of the second signal line (632) disposed on the third metal layer (L3) corresponding to the bendable portion (553) can be electrically connected to the second signal lines (632) disposed on the second metal layer (L2) corresponding to the first planar portion (551) and the second planar portion (552) through a via (e.g., via (910) of FIG. 17).

[0226] Referring to FIG. 20b, a support plate (550) according to one embodiment (e.g., the support plate (550) of FIG. 6) may have a difference in that the laminated structure of each of the differential signal line (630) and the ground line (640) is changed, unlike the embodiment of FIG. 20a. Hereinafter, only the embodiment of FIG. 20b that is different from the embodiment of FIG. 20a will be described. Accordingly, features not described in FIG. 20b will be replaced with the description of the embodiment of FIG. 20a.

[0227] According to one embodiment, in the first planar portion (551) and the second planar portion (552), the differential signal line (630) may be arranged on the third metal layer (L3). For example, in the first planar portion (551) and the second planar portion (552), the first signal line (631) and the second signal line (632) may be arranged with a gap therebetween.

[0228] According to one embodiment, in the first planar portion (551) and the second planar portion (552), the differential signal line (630) may be implemented in a stripline form in which a ground line (640) is disposed on each of its upper and lower portions. For example, in the first planar portion (551) and the second planar portion (552), the ground line (640) may be disposed on the first metal layer (L1) and the fourth metal layer (L4), and these may be disposed to at least partially overlap the first signal line (631) and the second signal line (632).

[0229] According to one embodiment, in the bendable portion (553), the differential signal line (630) may be arranged in a multi-layer structure. For example, in the bendable portion (553), the first signal line (631) may be arranged in the second metal layer (L2), and in the bendable portion (553), the second signal line (632) may be arranged in the third metal layer (L3). Here, the second signal line (632) may be arranged in the third metal layer (L3) so as to overlap at least partially with the first signal line (631). An end of the first signal line (631) arranged in the second metal layer (L2) corresponding to the bendable portion (553) may be electrically connected to the first signal lines (631) arranged in the third metal layer (L3) corresponding to the first planar portion (551) and the second planar portion (552) through a via (not shown).

[0230] According to one embodiment, in the bendable portion (553), the ground line (640) may be arranged on the first metal layer (L1) and may be arranged to at least partially overlap with the first signal line (631) and the second signal line (632).

[0231] According to one embodiment, the differential signal line (630) in the bendable portion (553) can be divided into a first region (6301) that overlaps with the ground line (640) and a second region (6302) that does not overlap with the ground line (640), taking impedance matching into consideration.

[0232] Referring to FIG. 21A, a support plate (550) according to one embodiment (e.g., the support plate (550) of FIG. 6) may have a difference in that the line width of the differential signal line (630) is increased, unlike the embodiment of FIG. 20A. Hereinafter, only the embodiment of FIG. 21A that is different from the embodiment of FIG. 20A will be described. Accordingly, features not described in FIG. 21A will be replaced with the description of the embodiment of FIG. 20A.

[0233] According to one embodiment, the support plate (550) can reduce DCR and reduce signal loss by increasing the line width of the differential signal line (630) in the first planar portion (551) and the second planar portion (552). As the line width of the differential signal line (630) increases, impedance can decrease, and the support plate (550) can take this into consideration to reduce the area where the differential signal line (630) and the ground line (640) overlap each other. Similarly, the support plate (550) can be designed so that the differential signal line (630) and the ground line (640) do not completely overlap each other in the bendable portion (553), thereby enabling impedance matching, reducing DCR and reducing signal loss due to the increased line width. For example, in the flexible portion (553), the differential signal line (630) can be divided into a first region (6301) that overlaps with the ground line (640) and a second region (6302) that does not overlap with the ground line (640).

[0234] According to one embodiment, the first signal line (631) in the bendable portion (553) can be divided into a first region (6301) that overlaps with the ground line (640) and a second region (6302) that does not overlap with the ground line (640), taking impedance matching into consideration.

[0235] According to one embodiment, the second signal line (632) in the bendable portion (553) may not completely overlap with the first signal line (631). According to one embodiment, the second signal line (632) may be divided into a third region (6304) overlapping with the ground line (640) and a fourth region (6305) not overlapping with the ground line (640), taking impedance matching into consideration. For example, the width of the fourth region (6305) of the second signal line (632) may be different from the width of the second region (6302) of the first signal line (631).

[0236] Referring to FIG. 21b, a support plate (550) according to one embodiment (e.g., the support plate (550) of FIG. 6) may have a difference in that the laminated structure of each of the differential signal line (630) and the ground line (640) is changed, unlike the embodiment of FIG. 21a. Hereinafter, only the embodiment of FIG. 21b, which is different compared to the embodiment of FIG. 21a, will be described. Therefore, features not described in FIG. 21b will be replaced with the description of the embodiment of FIG. 21a.

[0237] According to one embodiment, in the first planar portion (551) and the second planar portion (552), the differential signal line (630) may be arranged on the third metal layer (L3). For example, in the first planar portion (551) and the second planar portion (552), the first signal line (631) and the second signal line (632) may be arranged with a gap therebetween.

[0238] According to one embodiment, in the first planar portion (551) and the second planar portion (552), the differential signal line (630) may be implemented in a stripline form in which a ground line (640) is disposed on each of its upper and lower portions. For example, in the first planar portion (551) and the second planar portion (552), the ground line (640) may be disposed on the first metal layer (L1) and the fourth metal layer (L4), and these may be disposed to at least partially overlap the first signal line (631) and the second signal line (632).

[0239] According to one embodiment, in the bendable portion (553), the differential signal line (630) may be arranged in a multi-layer structure. For example, in the bendable portion (553), the first signal line (631) may be arranged in the second metal layer (L2), and in the bendable portion (553), the second signal line (632) may be arranged in the third metal layer (L3). Here, the second signal line (632) may be arranged in the third metal layer (L3) so as to overlap at least partially with the first signal line (631). An end of the first signal line (631) arranged in the second metal layer (L2) corresponding to the bendable portion (553) may be electrically connected to the first signal lines (631) arranged in the third metal layer (L3) corresponding to the first planar portion (551) and the second planar portion (552) through a via (not shown).

[0240] According to one embodiment, in the bendable portion (553), the ground line (640) may be arranged on the first metal layer (L1) and may be arranged to at least partially overlap with the first signal line (631) and the second signal line (632).

[0241] According to one embodiment, the differential signal line (630) in the bendable portion (553) can be divided into a first region (6301) that overlaps with the ground line (640) and a second region (6302) that does not overlap with the ground line (640), taking impedance matching into consideration.

[0242] According to one embodiment, the ground line (640) in the bendable portion (553) may be arranged in a single layer form. For example, the ground line (640) in the bendable portion (553) may be arranged in the first metal layer (L1).

[0243] Referring to FIG. 21c, a support plate (550) according to one embodiment (e.g., the support plate (550) of FIG. 6) may have a difference in that the line width of the differential signal line (630) is reduced, unlike the embodiment of FIG. 21b. Hereinafter, only the embodiment of FIG. 21c, which is different from the embodiment of FIG. 21b, will be described. Accordingly, features not described in FIG. 21c will be replaced with the description of the embodiment of FIG. 21b.

[0244] In the embodiment of FIG. 21c, compared to the embodiment of FIG. 21b, the distance between the differential signal line (630) and the overlapping ground line (640) may be changed. For example, in the first planar portion (551) and the second planar portion (552), the distance (d3) from the differential signal line (630) to the ground line (640) of the first metal layer (L1) positioned thereon may increase. For example, in the first planar portion (551) and the second planar portion (552), the distance (d4, d4 being smaller than d3) from the differential signal line (630) to the ground line (640) of the fourth metal layer (L4) positioned thereon may decrease. In this case, the impedance of the differential signal line (630) may be reduced compared to the embodiment of FIG. 21b. The embodiment of FIG. 21c can increase the impedance by relatively reducing the line width of the differential signal line (630) and relatively increasing the spacing between the first signal line (631) and the second signal line (632), taking into account the reduced impedance of the differential signal line (630) compared to the embodiment of FIG. 21b.
