Description
BACKGROUND
Field

The disclosure relates to a display and an including an antenna disposed adjacent to the display.


Description of Related Art

Recently, electronic devices (e.g., smartphones) have been introduced that adopt a so-called full display structure for minimizing/reducing the bezel and enlarging the active area. An electronic device adopting the full display structure has a display drive IC (hereinafter, ‘DDI’) and an antenna disposed adjacent to the display and may experience deterioration of antenna performance due to noise caused from the antenna by the DDI when the display is powered on. As an example, when a signal is transmitted from the antenna (e.g., when the maximum Tx power is generated from the antenna), the Tx power is induced in the DDI, and the induced Tx power and the DDI low-frequency noise are mutually modulated. The modulated noise is reinduced at the antenna, significantly deteriorating the reception (Rx) sensitivity of the antenna.


To address deterioration of antenna reception sensitivity as described above, it is preferable to shield the antenna and the DDI from each other but, due to recent design requirements for lighter and more compact electronic devices, it may be hard to adopt a structure for electromagnetically shielding the antenna and the DDI completely.


Thus, a DDI shielding member, e.g., in the form of a film or a tape, may be applied to shield between the DDI and the antenna, but this way cannot fully prevent deterioration of antenna performance. For example, inclusion of a shielding member has a limitation on preventing/reducing deterioration of antenna reception sensitivity when generating the maximum Tx power at the antenna.


SUMMARY

Embodiments of the disclosure provide a ground connecting structure for reducing deterioration of sensitivity of an antenna disposed adjacent to the display due to an influence by the noise (e.g., RF noise) from the display drive IC (DDI) in a device performing communication (e.g., radio frequency (RF) communication) with an external electronic device.


According to various example embodiments of the disclosure, there may be provided an electronic device comprising: a housing, a display, a ground sheet disposed on a rear surface of the display, a substrate disposed in an inner space of the housing, an antenna disposed on one side of the housing, and a flexible sheet including a display drive IC configured to control the display disposed thereon, wherein an opening through the flexible sheet is provided in an area between the display drive IC and the antenna, wherein a conductive member comprising a conductive material is disposed in the opening, and wherein noise induced at the antenna is reduced based on the conductive member being electrically connected to the ground sheet.


According to various example embodiments, there may be provided an electronic device comprising: a housing including a metal frame, a display, a ground sheet disposed on a rear surface of the display, a substrate disposed in an inner space of the housing, an antenna configured to perform communication with another electronic device using the metal frame, a flexible sheet including a display drive IC configured to control the display disposed thereon, and a shielding sheet configured to shield noise of the display drive IC, wherein an opening through the flexible sheet and the shielding sheet is provided in an area between the display drive IC and the antenna, wherein a conductive member comprising a conductive material is included and is disposed through the opening and spaced apart from the display drive IC by a specified interval in a first direction, and wherein the conductive member is connected to the ground sheet on one surface and is stacked with a conductive island formed in the housing along a second direction perpendicular to the first direction, on another surface.


According to various example embodiments, there may be provided an electronic device comprising: a housing, a display, a ground sheet disposed on a rear surface of the display, a substrate disposed in an inner space of the housing, an antenna disposed on at least one side of the housing, and a flexible sheet having a display drive IC configured to control the display disposed thereon, wherein the flexible sheet forms a first grounding point through an electrical connection with the substrate, and wherein noise induced at the antenna is reduced by forming a second grounding point through a conductive member comprising a conductive material disposed in an area between the display drive IC and the antenna and connected to the ground sheet on one surface and stacked with a conductive island formed in the housing on another surface.


In an electronic device according to various example embodiments of the disclosure, it is possible to prevent and/or reduce deterioration of antenna sensitivity by reducing the Tx power reinduced at the antenna through the DDI.


Various example embodiments of the disclosure may advantageously reduce deterioration of antenna performance caused by the display in line with the development trend of lightweight, thin, and compact electronic devices.

According to an embodiment, the battery 350 may be a device for supplying power to at least one component of the electronic device 101. The battery 189 may include, e.g., a primary cell which is not rechargeable, a secondary cell which is rechargeable, or a fuel cell. At least a portion of the battery 350 may be disposed on substantially the same plane as the printed circuit board 340. The battery 350 may be integrally or detachably disposed inside the electronic device 101.


According to various embodiments, the second supporting member 360 (e.g., a rear case) may be disposed between the printed circuit board 340 and the antenna 370. For example, the second supporting member 360 may include one surface to which at least one of the printed circuit board 340 and the battery 350 is coupled, and another surface to which the antenna 370 is coupled.


According to an embodiment, the antenna 370 may be disposed between the rear plate 380 and the battery 350. The antenna 370 may include, e.g., a near-field communication (NFC) antenna, a wireless charging antenna, and/or a magnetic secure transmission (MST) antenna.

According to various embodiments, the rear plate 380 may form at least a portion of the rear surface (e.g., the rear surface 310B of FIG. 3) of the electronic device 101.


The electronic device 101 disclosed in FIGS. 2, 3 and 4 has a bar-type or plate-type appearance but the disclosure is not limited thereto. For example, the illustrated electronic device may be part of a rollable electronic device or a foldable electronic device. “Rollable electronic device” may refer, for example, to an electronic device at least a portion of which may be wound or rolled or received in the housing 210 as the display may be bent and deformed. As the display is stretched out or is made visible to the outside in a larger area according to the user's need, the rollable electronic device may use an expanded second display area. “Foldable electronic device” may refer, for example, to an electronic device that may be folded in directions to face two different areas of the display or in directions opposite to each other. In general, in the portable state, the foldable electronic device may be folded so that the two different areas of the display face each other and, in an actual use state, the user may unfold the display so that the two different areas form a substantially flat shape. In various embodiments, according to various embodiments of the disclosure, the electronic device 101 may be understood as including various electronic devices, such as a laptop computer or a home appliance, as well as a portable electronic device, such as a smart phone.


Referring back to FIG. 4, an electronic device 101 including the display 320 may include a display drive IC (hereinafter, abbreviated as “DDI”) (hereinafter, the DDI 321 of FIG. 5 described below). According to an embodiment, the DDI 321 may be disposed on a flexible sheet (hereinafter, the flexible sheet 322 of FIG. 5 described below).


A ground connecting structure in which an antenna disposed adjacent to the display 320 is affected by noise (e.g., RF noise) caused by the DDI 321 to reduce deterioration in the electronic device 101 performing communication (e.g., the second network communication 199 of FIG. 1) with an external electronic device (e.g., the external electronic device 102 or 104 or the server 108 of FIG. 1) is described in greater detail below with reference to FIGS. 5 to 19. In the following description, the DDI 321 is illustrated as being disposed adjacent to a lower end (e.g., portion A of FIG. 4) of the electronic device 101, but it should be noted that the position of the DDI 321 is not necessarily limited thereto. For example, the DDI 321 may be disposed adjacent to an upper end of the electronic device 101 or a side surface of the electronic device 101. For example, a ground connecting structure for reducing deterioration of antenna sensitivity due to an influence of noise (e.g., RF noise) by the DDI 321 based on an example in which the DDI 321 is disposed adjacent to a lower end (e.g., portion A of FIG. 4) of the electronic device 101 may be described below. These descriptions may also be applied to an embodiment in which the DDI 321 is disposed adjacent to an upper end of the electronic device 101 or a side surface of the electronic device 101.



FIG. 5 is a diagram illustrating a state in which the sensitivity of an antenna is deteriorated due to an influence of noise (e.g., RF noise) by a display drive IC (DDI) according to an comparative embodiment. FIG. 6 is a diagram illustrating a state in which deterioration of antenna sensitivity is reduced when a ground connecting structure is included according to various embodiments.


An electronic device (e.g., the electronic device 101 of FIGS. 1 to 4) according to the embodiments of FIGS. 5 and 6 may include a housing (e.g., the housing 210 of FIGS. 2 and 3), a display 320 (e.g., the display 201 of FIGS. 2 and 3 or the display 320 of FIG. 4), and a DDI 321 for controlling the display 320.


According to various embodiments, the DDI 321 may be connected to a display (e.g., the display 320 of FIG. 4) in a chip on film (COF), chip on pane (COP), or chip on glass (COG) manner. For example, referring to FIG. 5, in a chip on film (COF) manner, it is illustrated that the DDI 321 is disposed on one surface 322a of the flexible sheet 322, and the flexible sheet 322 has one portion connected to the display 320 and another portion connected to a printed circuit board (PCB) 324 (hereinafter, simply referred to as a substrate 324). In this case, the substrate 324 may be disposed on the rear surface of the display 320.


The electronic device 101 may have an antenna 390 disposed adjacent to the display 320 and the DDI 321. According to an embodiment, the antenna 390 may be an antenna for communicating with another electronic device (e.g., the external electronic devices 102 and 104 or the server 108 of FIG. 1) using at least a portion of a conductive portion (e.g., a metal frame) of the housing. For example, the antenna 390 may be an antenna for performing cellular communication (e.g., 2G, 3G, 4G, LTE, 5G, mm Wave, 60 GHz, or WiGig communication), short-range communication (e.g., Wi-Fi, Bluetooth, or NFC), and/or global navigation satellite system (GNSS).


According to an embodiment, the antenna 390 may be disposed at a position different from that of the antenna 370 described above in FIG. 4, e.g., on a side surface of the housing. The side surface of the housing may be formed of a metal material and/or a non-metal (e.g., polymer) material. The side surface of the metal housing may be utilized as an antenna.


In an electronic device (e.g., the electronic device 101 of FIGS. 1 to 4) having such a structure, when the display is powered on, noise may be induced at the antenna 390 by the DDI 321, and thus antenna performance may be deteriorated. For example, as illustrated in FIG. 5, when the antenna 390 transmits a signal, the antenna 390 may generate Tx power T2 radiated to the inside of the electronic device together with Tx power T1 radiated to the outside. The Tx power T2 radiated to the inside of the electronic device may flow through the DDI 321 to a grounding point (the first grounding point P1) connected to the substrate 324. When Tx power is maximally generated at the antenna 390, the Tx power T2 may be induced in the DDI 321, and the induced Tx power T2 and DDI low frequency noise may be modulated with each other. Further, as the modulated noise is reinduced into the antenna 390, the reception (Rx) sensitivity of the antenna 390 may be significantly reduced.


According to various embodiments, the electronic device (e.g., the electronic device 101 of FIGS. 1 to 4) may further include a DDI shielding sheet 323 in the form of a film or tape to shield between the DDI 321 and an antenna in order to prevent and/or reduce DDI low-frequency noise from occurring. However, even when the DDI shielding sheet 323 is applied, DDI low-frequency noise generation is not completely prevented, and there is also a limitation in reducing antenna performance deterioration. For example, the maximum Tx power may be generated at the antenna 390, and it may be difficult to prevent or reduce the decrease in the reception sensitivity of the antenna merely by having the DDI shielding sheet 323.


According to various embodiments of the disclosure, it is possible to provide a ground connecting structure for preventing and/or reducing a decrease in reception sensitivity of the antenna 390 in the comparative embodiment of FIG. 5. The electronic device (e.g., the electronic device 101 of FIGS. 1 to 4) according to various embodiments of the disclosure may include an opening 326 formed through the flexible sheet 322 and the DDI shielding sheet 323 in an area between the DDI 321 and the antenna 390 and a grounding conductive member 325 disposed in the opening, as the ground connecting structure as shown in FIG. 6.


Referring to FIG. 6, when the antenna 390 transmits a signal to an external electronic device, the antenna 390 may generate Tx power T2 radiated to the inside of the electronic device together with Tx power T1 radiated to the outside. In the embodiment illustrated in FIG. 6, as the grounding conductive member 325 is disposed in the area between the DDI 321 and the antenna 390, a portion of the Tx power T2 radiated to the inside of the electronic device may flow to the grounding point (second grounding point P2) connected through the conductive member 325, so that Tx power T3 which is reduced as compared with the Tx power T2 initially radiated may flow through the DDI 321 to the grounding point (first grounding point P1) connected with the substrate 324. Accordingly, even when the Tx power T3 induced at the DDI 321 and the DDI low frequency noise are modulated with each other, the modulated noise induced again to the antenna 390 may be smaller than in the comparative embodiment illustrated in FIG. 5.


In summary, the electronic device (e.g., the electronic device 101 of FIGS. 1 to 4) according to various embodiments of the disclosure may have the second grounding point P2 formed through the conductive member 325 disposed in the area between the DDI 321 and the antenna 390 as well as the first grounding point P1 of the flexible sheet 322 electrically connected with the substrate 324, thereby reducing the modulated noise reinduced to the antenna 390. Accordingly, the reception (Rx) sensitivity of the antenna 390 in the embodiment illustrated in FIG. 6 may be enhanced compared to the comparative embodiment illustrated in FIG. 5.


The position of the opening 326 in which the conductive member 325 is disposed is described in greater detail below with reference to FIGS. 7 and 8.



FIG. 7 is a diagram illustrating rear view of a state in which a flexible sheet and a display drive IC are stretched out, according to various embodiments. FIG. 8 is a diagram illustrating side view of a state in which a flexible sheet and a display drive IC are stretched out, according to various embodiments.



FIGS. 7 and 8 are views for helping understanding of the DDI 321 disposed in a chip on film (COF) manner. Unlike FIG. 6 in which the flexible sheet 322 is bent with respect to the display 320, FIGS. 7 and 8 may show that the flexible sheet 322 is not bent with respect to the display 320 but is stretched out flat between the display 320 and the substrate 324.


According to various embodiments, the flexible sheet 322 may be formed of one of a flexible printed circuit board (flexible PCB (FPCB) or rigid flexible PCB (RFPCB)) or a flexible film or a combination of the flexible printed circuit board and the flexible film.


According to various embodiments, one end of the flexible sheet 322 may be connected to one side of the display 320, and the other end may be connected to the substrate 324. The DDI 321 may be disposed on one surface 322a of the flexible sheet 322. In the embodiment of FIG. 6, the flexible sheet 322 is bent with respect to the display 320, and the position of the opening 326 in which the grounding conductive member (e.g., the grounding conductive member 325 of FIG. 6) is disposed may be formed in an area between the DDI 321 and the antenna 390. In the embodiments of FIGS. 7 and 8, a state in which the flexible sheet 322 is stretched out flat with respect to the display 320 is illustrated. In this case, the position of the opening 326 in which the grounding conductive member (e.g., the grounding conductive member 325 of FIG. 6) is disposed may be formed in the area between the display 320 and the DDI 321. Referring to FIGS. 6 to 8 together, the bent state as in the embodiment shown in FIG. 6 may be implemented by bending the flexible sheet 322 to allow the substrate 324 to be positioned on the rear surface 320a of the display 320 in a state in which one end of the flexible sheet 322 is fixed to the substrate 324. Using the flexible sheet 322, it is possible to move the position of the DDI 321 for the control operation of the display 320 toward the rear surface 320a of the display 320, to enlarge the size area of the display 320, and to shrink the bezel, which is the inactive area. The bending of the flexible sheet 322 may be performed at a portion adjacent to the side surface (or the side surface of the housing) of the electronic device, and the DDI 321 may be disposed at a position adjacent to the side surface (or the side surface of the housing) of the electronic device.


Hereinafter, various ground connecting structures of the disclosure are described in greater detail with reference to FIGS. 9 to 15.



FIG. 9 is a diagram illustrating a rear view of a display having a display drive IC shielding sheet according to various embodiments. FIG. 10 is a diagram illustrating a first grounding point on a rear surface of a display according to various embodiments. FIGS. 9 and 10 are enlarged views illustrating part A of FIG. 4.


According to various embodiments, the substrate 324 may be disposed on the rear surface 320a of the display 320, and the position thereof may be fixed on the rear surface 320a of the display 320. Corresponding thereto, a portion of the flexible sheet 322 in a bent state may be disposed on the rear surface 320a of the display 320. The DDI 321 may be disposed on one surface of the flexible sheet 322. As illustrated in FIGS. 9 and 10, the flexible sheet 322 may have a structure that is bent at an edge of the display 320, e.g., a position adjacent to a side surface of the electronic device (e.g., a lower portion end of the electronic device).


Referring to FIG. 9, when the rear surface 320a of the display 320 is viewed, the DDI shielding sheet 323 may be stacked with the flexible sheet 322 to cover the flexible sheet 322. In the embodiment illustrated in FIG. 10, the DDI shielding sheet 323 is omitted in FIG. 9, and one end of the flexible sheet 322 is connected to the substrate 324. The other end of the flexible sheet 322 may be connected to the rear surface 320a of the display 320, although not shown in the drawings.


According to various embodiments, a grounding point (the first grounding point P1) for grounding Tx power passing through the DDI 321 may be formed on the substrate 324. Since the flexible sheet 322 has small rigidity and has a structure that is bent at a position adjacent to the side surface of the electronic device, it may be difficult to form a grounding point in the structure. Accordingly, according to various embodiments, as a grounding point for grounding Tx power, the first grounding point P1 may be formed on the substrate 324. According to various embodiments, a plurality of first grounding points P1 may be provided on the substrate 324, and may be formed at various positions on the substrate 324. In this case, the first grounding point P1 may be formed at a position farther from the side surface (e.g., the side surface positioned in the +Y direction) of the electronic device than the position where the DDI 321 is disposed. Since the first grounding point P1 is formed at a position farther from the side surface of the electronic device than the position where the DDI 321 is disposed, when Max Tx power is generated at the antenna 390, the Tx power T2 may be induced at the DDI 321, and it may be difficult to prevent or reduce reinduction to the antenna 390 of the modulated noise of the induced Tx power T2 and the DDI low-frequency noise.


Accordingly, the electronic device (e.g., the electronic device 101 of FIGS. 1 to 4) according to various embodiments of the disclosure may provide another grounding point (second grounding point P2) formed between the DDI 321 and the side bezel structure (or antenna disposed on the side surface of the electronic device) of the electronic device and provided separately from the first grounding point P1.


Hereinafter, another grounding point (the second grounding point P2) is described in greater detail with reference to FIGS. 11 to 14.


First, the opening is described in greater detail with reference to FIG. 11.



FIG. 11 is a diagram illustrating a flexible sheet having an opening according to various embodiments.


According to various embodiments, the flexible sheet 322 may include a plurality of conductive lines 327. According to various embodiments, the plurality of conductive lines 327 may be signal lines provided to electrically connect the DDI 321 and the display 320. The plurality of conductive lines 327 may be connected to the DDI 321 disposed on the flexible sheet 322, and the plurality of conductive lines 327 may stay bundled.


According to various embodiments, the opening 326 formed in the flexible sheet 322 may be formed not to overlap the plurality of conductive lines 327. For example, the plurality of conductive lines 327 may be designed to avoid the opening 326.


According to various embodiments, the opening 326 may be formed in various shapes such as a circular shape, an oval shape, or a rectangular shape. However, according to an embodiment, considering that the conductive lines 327 extend from the DDI 321 to the display 320, the opening 326 may be formed in a trapezoidal shape with a short top or a triangular shape with a vertex facing the DDI 321. FIG. 11 illustrates, as an example, a trapezoidal opening 326 having a short top surface.


Although only one opening 326 is illustrated in FIG. 11, two openings 326 are illustrated in FIG. 12A and the subsequent drawings, and a plurality of openings 326 not illustrated in the drawings may be provided.

FIG. 12B is a diagram illustrating a display drive IC shielding sheet having an opening according to various embodiments. FIG. 12C is a diagram illustrating a display drive IC shielding sheet in a state in which a conductive member is formed in an opening according to various embodiments. FIG. 12D is a diagram illustrating a state in which a conductive island is disposed at a position corresponding to the conductive member according to various embodiments.


A DDI shielding sheet 323 is provided to prevent and/or reduce noise from being induced at the antenna due to a close arrangement between the DDI 321 and the antenna (e.g., the antenna disposed at the lower end of the electronic device), and may include a kind of shielding tape. Referring to FIG. 12A, the DDI shielding sheet 323 may be disposed to cover a substantial portion of the flexible sheet 322 on which the substrate 324 and the DDI 321 are disposed.


A ground sheet (the ground sheet 328 of FIG. 17 described below) may be disposed on the rear surface 320a of the display 320. The ground sheet may be stacked on the rear surface 320a of the display 320.


Referring to FIGS. 12A and 12B together, since the DDI shielding sheet 323 is formed to cover the flexible sheet 322, an opening 326 for disposing a grounding conductive member (e.g., the grounding conductive member 325 of FIG. 6) may also be formed in the DDI shielding sheet 323. Hereinafter, to be distinguished from the opening 326 formed in the flexible sheet 322, the opening formed in the flexible sheet 322 may be referred to as a first opening 326a, and the opening formed in the DDI shielding sheet 323 may be referred to as a second opening 326b. In this case, the first opening 326a formed in the flexible sheet 322 may be formed at a position corresponding to the second opening 326b formed in the DDI shielding sheet 323.


Referring to FIG. 12C, the grounding conductive member 325 may be disposed through the openings (the first opening 326a and the second opening 326b). According to various embodiments of the disclosure, by disposing the conductive member 325, an additional grounding path may be formed between the DDI 321 and a side surface (or an antenna disposed adjacent to the side surface) of the electronic device.


According to various embodiments, the conductive member 325 may include an elastic material such as sponge, foam, or poron, or may include a c-clip. Using a material having an elastic material as the conductive member 325, the pressure applied to the display 320 may be reduced, preventing/reducing damage to the display 320.


Referring to FIGS. 12C and 12D together, the conductive member 325 may be disposed at a position corresponding to the conductive island 332 disposed in the housing. According to an embodiment, the conductive island 332 may be a portion fixedly disposed to a supporting member inside the housing, and may include, e.g., a metal material. According to an embodiment, the conductive member 325 may be stacked with the conductive island 332 along the height direction of the electronic device. The conductive member 325 may be stacked with the conductive island 332, providing a grounding path from the conductive member 325 to the conductive island 332. According to an embodiment, the conductive island 332 may include a metal bracket for fixing the socket inside the housing. For example, the conductive island 332 may be a metal bracket for screw hole assembly for fixing a connector socket.


Hereinafter, the conductive island 332 is described in greater detail with reference to FIGS. 13 and 15D.



FIG. 13 is a perspective view illustrating a supporting member according to various embodiments. FIG. 14 is a cross-sectional view illustrating the supporting member of FIG. 13, taken along direction B-B′ according to various embodiments.


According to various embodiments, the supporting member 330 may be provided to support and/or couple other components (e.g., the display 320, the printed circuit board 340, and/or various electronic components). The supporting member 330 is a material having high rigidity for supporting and/or coupling other components (e.g., the display 320, the printed circuit board 340, and/or various electronic components), and may include, e.g., metal or non-metal (e.g., polymer or polycarbonate (PC)). The supporting member 330 may include one surface 330a facing the rear surface (the rear surface 320a of FIGS. 12A to 12D) of the display 320. At least a portion of the supporting member 330 may be formed of a conductive portion 330-1 to provide an electrical path, and another portion of the supporting member 330 may be formed of a non-conductive portion 330-2. For example, as illustrated in FIG. 13, a substantial portion of the supporting member 330 may be formed of the conductive portion 330-1 (e.g., the hatched portion of FIG. 13), and a portion adjacent to the side bezel structure 331 may be formed of the non-conductive portion 330-2 (e.g., the non-hatched portion of FIG. 13) to utilize a portion of the side bezel structure 331 as an antenna. For example, FIG. 13 illustrates that a portion adjacent to the lower end of the electronic device is formed of the non-conductive portion 330-2.


Although not shown separately in the drawings, according to various embodiments, a second shielding sheet (not shown) may be formed in the non-conductive portion. The second shielding sheet (not shown) is provided to prevent and/or reduce noise from being induced at the antenna due to mutual influence by the close arrangement between the DDI 321 and the antenna (e.g., the antenna disposed at a lower end of the electronic device) of the electronic device, similarly to the DDI shielding sheet 323 (which may be referred to hereinafter as a first shielding sheet 323 to be distinguished) described above, and may include a kind of shielding tape. As another example, the second shielding sheet (not shown) may be a shielding sheet provided in the supporting member 330, unlike the DDI shielding sheet 323 disposed to cover one surface of the flexible sheet 322.


Referring to FIGS. 13 and 14 together, according to various embodiments, a conductive island 332 for forming a grounding point (the second grounding point P2) may be disposed in the non-conductive portion 330-2 adjacent to the lower end of the electronic device. In the conductive island 332, non-conductive materials may be formed around a corresponding component, and the corresponding component itself may include a material (e.g., metal) for forming an electrical path. Referring to the cross section of the supporting member 330 illustrated in FIG. 14, the conductive island 332 may be present at a position spaced apart from the conductive portion 330 and the side surface (or the antenna 390 positioned on the side surface of the electronic device) of the electronic device. For example, the conductive island 332 may be formed at a position surrounded by the non-conductive portion between the antenna 390 positioned in the side bezel structure 331 and the conductive portion 330-1 of the supporting member 330.


As described above, it should be noted that the description of the position of the conductive island 332 is intended to help understanding, and is not intended as limited to any particular embodiment. For example, the conductive island 332 forming the grounding point may not be limited as being disposed at a position adjacent to the lower end of the electronic device. Various positions of the conductive island 332 which forms the grounding point may be set corresponding to various positions of the DDI 321 disposed in the electronic device.



FIG. 15A is a diagram illustrating a state in which a conductive island is disposed on a supporting member according to various embodiments. FIG. 15B is a diagram illustrating a state in which a socket is disposed on a supporting member according to various embodiments. FIG. 15C is a diagram illustrating a state in which a coupling member is coupled to a socket according to various embodiments.



FIG. 15A illustrates one surface 330a of the supporting member 330 of FIGS. 13 and 14 viewed from above the display of the electronic device. Referring to FIG. 15A, the conductive island 332 may be positioned between the DDI 321 and the side bezel structure 331. FIG. 15B illustrates another surface 330b of the supporting member 330. For example, FIG. 15A illustrates the front surface of the supporting member 330, and FIG. 15B illustrates the rear surface of the supporting member 330. In addition to the display 320 or the printed circuit board (e.g., the substrate 324) being coupled to the supporting member 330, various electronic components such as the socket 333 and the fingerprint recognition sensor 335 may be disposed on the supporting member 330.


According to various embodiments, the position of the conductive island 332 may correspond to the position of the socket 333 coupled to the supporting member 330. Referring to FIGS. 15A and 15B together, it may be identified that the conductive island 332 is disposed at a position corresponding to the socket 333 coupled to the supporting member 330. The socket 333 may be, e.g., a socket to which a connector (e.g., a USB connector) for transmitting and receiving power and/or data to and from an external electronic device is connected, and may be formed at a position corresponding to a connector hole h (e.g., the first connector hole 208 of FIG. 2) capable of receiving the connector (e.g., the USB connector).


Referring to FIG. 15C, the conductive island 332 may correspond to a metal bracket for assembling the screw 334 for fixing the socket 333 inside the housing. According to an embodiment, the conductive island 332 is a portion fixedly disposed to the supporting member 330, and a screw hole h2 for assembling the screw 334 may be formed. The socket 333 may be fixedly disposed by tightening the screw 334 while being received in the screw hole h2 after placing the socket 333 at a designated position.


However, the socket 333 may not be limited to any specific type. For example, the tray hole 209 illustrated in FIGS. 2 and 3 and the corresponding socket for receiving the SD card tray may also correspond to the socket 333 of the present disclosure. Various positions and shapes may be applied to the conductive island 332, corresponding to the position and shape of the socket 333.


Hereinafter, an electronic device adopting a ground connecting structure according to various embodiments of the disclosure is described in greater detail with reference to FIGS. 16 to 19, based primarily on the arrangement relationship between the components of the electronic device.



FIG. 16 is a perspective view illustrating an electronic device according to various embodiments. FIG. 17 is a cross-sectional view illustrating an electronic device including a ground connecting structure according to various embodiments. FIG. 18 is a cross-sectional view illustrating an electronic device including a ground connecting structure according to various embodiments.



FIG. 16 is a view illustrating an electronic device 101 including a housing (e.g., the housing 210 of FIGS. 2 and 3) and a display 320 according to various embodiments, and FIGS. 17 and 18 are views illustrating a portion of a cross section of the electronic device 101 of FIG. 16, taken along direction D-D′ with respect to the conductive member 325. FIG. 18 illustrates that various components (e.g., the second substrate 340) including the supporting member 330 are omitted from FIG. 17.


Referring to FIG. 16, the electronic device 101 may include a housing (e.g., the housing 210 of FIGS. 2 and 3) and a display 320. The display 320 may be visible to the outside through another portion (e.g., the front plate 310) of the housing while being surrounded by a portion (e.g., the side bezel structure 331) of the housing. For example, the display 320 may be disposed on the rear surface of the front plate 310, and may display a screen to the outside of the electronic device through the substantially transparent front plate 310.


In the electronic device 101 according to various embodiments of the disclosure, at least a portion of the side bezel structure 331 of the housing may be formed of a conductive portion (e.g., a metal frame). In an embodiment, the conductive portion (e.g., a metal frame) may be utilized as an antenna. Further, the electronic device 101 may include the DDI 321 disposed on the rear surface of the display 320, and may include the conductive member 325 for forming a grounding point between the DDI 321 and the side bezel structure 331 of the housing (or the antenna 390 disposed on the side surface of the housing).


Referring to FIGS. 17 and 18, according to various embodiments, the display 320 may form a stacked structure with various layers adjacent thereto. For example, a plurality of layers such as an adhesive layer 311 or a polarization layer 312 may be disposed between the display 320 and the front plate 310, and a ground sheet 328 may be disposed on another surface of the display 320. The plurality of layers may be stacked together with the display 320 in the height direction (e.g., the Z-axis direction) of the electronic device 101. According to various embodiments, the ground sheet 328 may be a component disposed on the rear surface of the display 320 and may provide a ground area on the rear surface of the display 320.


The electronic device 101 may further include various substrates 324 and 340 in the inner space of the housing. For example, various electronic components or various components such as the connector 336 may be disposed on the substrates 324 and 340. According to various embodiments, through a certain substrate 324, the flexible sheet 322 may be supported, or a grounding point (e.g., the first grounding point P1 of FIG. 5) may be provided.


At least a portion of the flexible sheet 322 may be bent at a position adjacent to one side (e.g., the side bezel structure 331) of the housing. The DDI 321 may be disposed on a flat surface of the flexible sheet 322, and the DDI 321 and the flat surfaces around the DDI 321 may be covered by the DDI shielding sheet 323. Further, an opening 326 may be formed through the flexible sheet 322 in an area between the DDI 321 and the side bezel structure 331 (or the antenna 390) of the housing. According to an embodiment, the opening 326 may be formed to penetrate the flexible sheet 322 and the DDI shielding sheet 323 covering the flat surface of the flexible sheet 322.


According to various embodiments, the conductive member 325 may be disposed in the opening 326. According to an embodiment, the conductive member 325 may be disposed at a position spaced apart from the DDI 321 by a predetermined interval in the length direction (the first direction (Y-axis direction)) of the electronic device. As the conductive member 325 is disposed in the opening 326 and one surface is electrically connected to the ground sheet 328, a grounding point (e.g., the second grounding point P2 of FIG. 6) for reducing noise induced at the antenna 390 may be formed.


According to various embodiments, one surface of the conductive member 325 may contact the ground sheet 328, and the other surface of the conductive member 325 may contact the conductive island 332 provided in the supporting member 330. According to an embodiment, the conductive member 325 may be stacked together with the conductive island 332 along the height direction (the second direction (the Z-axis direction)) of the electronic device 101. For example, the conductive island 332 may be a metal bracket for assembling the screw 334 for fixing the socket 333 inside the housing. In an embodiment, the conductive member 325 may include an elastic material, and thus, as the screw 334 for fixing the socket 333 is tightened inside the housing, the conductive member 325 may maintain a stable contact point without being damaged even when a predetermined amount of pressing is applied.



FIG. 19 is a diagram illustrating an electronic device including a ground connecting structure according to various embodiments.



FIG. 19 is a view schematically illustrating main components in the electronic device 101 of FIGS. 16 to 18.


Referring to FIG. 19, the electronic device 101 may have a first grounding point P1 of the flexible sheet 322 electrically connected to the substrate 324, and may additionally form a second grounding point P2 through the conductive member 325 disposed in an area between the DDI 321 and the antenna 390. Further, a third grounding point P3 may be formed through the socket 333 and the conductive island 332 stacked with the conductive member 325. As such, the electronic device 101 according to various embodiments of the disclosure may not only form a grounding point (the first grounding point P1) at a position farther than the DDI 321 with respect to the side surface of the electronic device (or the antenna 390 disposed on the side surface of the electronic device), but also form an additional grounding point (the second grounding point P2 and/or the third grounding point P3) at a position closer to the DDI 321, thereby reducing the modulated noise reinduced to the antenna 390.



FIG. 20A is a diagram illustrating an enlarged shape of a conductive island 332 according to various embodiments. FIG. 20B is a diagram illustrating an enlarged shape of a conductive island 332 according to various embodiments. FIG. 20C is a diagram illustrating an enlarged shape of a conductive island 332 according to various embodiments.


The conductive island 332 may be a portion fixedly disposed on the supporting member 330, and may be a portion in which a screw hole h2 for assembling a screw (e.g., the screw 334 of FIG. 15C) is formed. As illustrated in FIG. 15A, the conductive island 332 may have only a size sufficient to form the screw hole h2, and an additional grounding point may be formed using the conductive island 332. However, examples of the conductive island 332 may not necessarily be limited thereto.


For example, as illustrated in FIGS. 20A and 20B, the conductive island 332 may include a first extension portion 332a formed on one side of any one of the pair of conductive islands 332. As another example, as shown in FIG. 20C, each of the pair of conductive islands 332 may include the first extension portion 332a formed on one side thereof. In an embodiment, the screw hole h2 is not formed in the first extension portion 332a, and may be provided solely for forming an additional grounding point by being stacked with the conductive member 325. As another example, when the conductive island 332 is a metal bracket for assembling the screw 334 for fixing the socket 333 inside the housing, if the position of the metal bracket and the position of the conductive member 325 do not correspond to each other (e.g., if they are not aligned with each other in the +Z direction), the metal bracket may be modified in design to include the first extension portion 332a to provide a grounding point.



FIG. 21 is a diagram illustrating a state in which a conductive island 332 and a supporting member 330 are connected according to various embodiments.


Referring to FIG. 21, the conductive island 332 may include a second extension portion 332b elongated from one side of any one of the pair of conductive islands 332. As another example, unlike shown in FIG. 21, each of the pair of conductive islands 332 may include the first extension portion 332a formed on one side thereof. The second extension portion 332b may be a component for connecting the conductive island 332 and the supporting member 330. When the conductive island 332 is not connected to the ground sheet 328, another path for grounding the conductive island 332 may be provided using the second extension portion 332b connecting the conductive island 332 to the supporting member 330.



FIG. 22A is a diagram illustrating a simulation of distribution of current flowing when TX power is induced at a DDI according to a comparative embodiment. FIG. 22B is a diagram illustrating a simulation of distribution of current flowing when TX power is induced at a DDI according to another comparative embodiment. FIG. 22C is a diagram illustrating a simulation of distribution of current flowing when TX power is induced at a DDI according to various embodiments of the disclosure.



FIG. 22A is a diagram illustrating a comparative embodiment, and may show a simulation result of an electronic device including a shielding sheet on each of a rear surface 320a of the display 320 and one surface 330a of the supporting member 330. FIG. 22B is a diagram illustrating another comparative embodiment, and may show a simulation result of an electronic device including a shielding sheet only on the rear surface of the display 320. FIG. 22C is a diagram illustrating a simulation result of an electronic device including a shielding sheet only on the rear surface of the display 320 and forming a grounding point using the conductive member 325 between the DDI 321 and the antenna 390 according to various embodiments of the disclosure. In this case, FIGS. 22A to 22C may show a current distribution in a state in which Tx power of the same magnitude is induced from the antenna 390.


Referring to FIG. 22A, when the shielding sheet is included on each of the rear surface 320a of the display 320 and the one surface 330a of the supporting member 330, it may be identified that a current of up to 7.6 A/m flows near the DDI. Referring to FIGS. 22A and 22B together, when the shielding sheet is provided only on the rear surface 320a of the display 320, it may be identified that a current of up to 8.2 A/m flows around the DDI. Referring to FIG. 22C, when the shielding sheet is removed from one surface 330a of the supporting member 330 and the shielding sheet is provided only on the rear surface 320a of the display 320, it may be identified that a current of 5.9 A/m, which is significantly reduced from that in the embodiment illustrated in FIG. 22B, flows. Further, as compared with FIG. 22A, even when the shielding sheet is provided only on the rear surface 320a of the display 320, it may be identified that a current significantly smaller than the current value measured in FIG. 22A flows.


As such, in the electronic device according to various embodiments of the disclosure, by forming a grounding point using the conductive member 325 between the DDI 321 and the antenna 390, Tx power reinduced to the antenna through the DDI may be reduced, thereby preventing and/or reducing antenna sensitivity deterioration.


The electronic device according to various embodiments of the disclosure may be one of various types of electronic devices. The electronic devices may include, for example, a portable communication device (e.g., a smartphone), a computer device, a portable multimedia device, a portable medical device, a camera, a wearable device, a home appliance, or the like. According to an embodiment of the disclosure, the electronic devices are not limited to those described above.
