Specific details for implementing the invention

[0028] Hereinafter, some embodiments of the present invention will be described in detail with reference to the exemplary drawings. In assigning reference numerals to the components of each drawing, the same components may have the same reference numeral as much as possible, even if they are shown in different drawings. Furthermore, in describing the present invention, if it is determined that a detailed description of related known components or functions may obscure the essence of the present invention, such detailed description may be omitted. Where terms such as "comprising," "having," or "consisting of" are used in this specification, other parts may be added unless "only" is used. Where a component is expressed in the singular, it may include a plural unless there is a special explicit description otherwise.

[0029] Additionally, terms such as first, second, A, B, (a), (b), etc., may be used to describe the components of the present invention. These terms are used merely to distinguish the components from other components, and the essence, order, sequence, or number of the components are not limited by such terms.

[0030] In describing the positional relationship of components, where it is stated that two or more components are "connected," "combined," or "joined," it should be understood that while the two or more components may be directly "connected," "combined," or "joined," they may also be "connected," "combined," or "joined" with other components "intervened."

[0032] Meanwhile, where numerical values ​​or corresponding information regarding a component (e.g., levels, etc.) are mentioned, even without separate explicit notation, the numerical values ​​or corresponding information may be interpreted as including a range of error that may occur due to various factors (e.g., process factors, internal or external shocks, noise, etc.).

[0033] FIG. 1 is a diagram showing the schematic configuration of a communication device including a connecting member according to embodiments of the present invention.

[0034] Referring to FIG. 1, a communication device (100) according to an embodiment of the present invention may include a cover glass (150) and a housing (110), a printed circuit board (130) and a display panel (140) located between them, and a connecting member (120) connecting the housing (150) and the printed circuit board (PCB, 130).

[0035] At this time, the communication device (100) according to the embodiment of the present invention may omit some of the components shown in FIG. 1 or additionally include other components not shown. Also, the stacking order of the components included in the communication device (100) according to the embodiment of the present invention may differ from the stacking order shown in FIG. 1.

[0036] Here, the cover glass (150) corresponds to a cover made of a transparent material that forms the upper surface of the communication device (100), and may also be referred to as an upper housing. In this case, the cover glass (150) corresponding to the upper housing and the housing (110) located at the bottom may be collectively referred to as a housing.

[0037] The housing (110) can protect components included in the communication device (100). For example, a printed circuit board (130), a display panel (140), and a battery, etc., may be housed between the cover glass (150) and the housing (110), and the housing (110) can protect these components from external impact. The housing (110) may be formed of tempered glass, plastic, and / or metal, etc.

[0038] At this time, in order to improve the performance and design of the communication device (100), the exterior of the communication device (100) may be constructed with a housing (110) made of metal or a similar material.

[0039] In particular, the communication device may include an antenna capable of transmitting or receiving wireless signals of various frequencies, at least a portion of the housing (110) may be used as a radiator for the antenna, and the antenna may be a film type or a patch type and may be placed in the housing (110) located at the top or bottom of the communication device (100).

[0040] In the housing (110), an antenna may be formed, and a conductive area that transmits a signal transmitted from the antenna and a non-conductive area that does not transmit a signal may be formed.

[0041] For example, the housing (110) of the communication device (100) may include a first conductive area (111) for transmitting and receiving signals in a high frequency band, a third conductive area (113) for transmitting and receiving Wi-Fi signals, and a second conductive area (112) corresponding to an antenna ground area. In this case, at least a portion of the first conductive area (111) or the third conductive area (113) may be used as a radiator for the antenna.

[0042] The first conductive region (111), the second conductive region (112), and the third conductive region (113) can each be physically separated. For example, a non-conductive material (e.g., plastic) may be placed between the first conductive region (111) and the second conductive region (112) to form a non-conductive region (114) that separates the first conductive region (111) and the second conductive region (112). Additionally, a non-conductive region in which a non-conductive material is located may also be formed between the second conductive region (112) and the third conductive region (113).

[0043] The cover glass (150) is made of a transparent material that can transmit light generated from the display panel (140), and the user can perform touch actions by touching a finger or a stylus pen to the surface of the cover glass (150). For example, the cover glass (150) may be formed of tempered glass, reinforced plastic, a flexible polymer material, etc.

[0044] The printed circuit board (130) can mount various electronic components, elements, or printed circuits of the communication device (100). For example, the printed circuit board (130) may include a wireless communication circuit (131) including a communication processor, an application processor, and memory.

[0045] The wireless communication circuit (131) may be electrically connected to the first conductive area (111) or the third conductive area (113) through signal wiring. The wireless communication circuit (131) may apply current to the first conductive area (111) or the third conductive area (113) through signal wiring and transmit or receive a signal of a specified frequency band based on an electrical path formed through the first conductive area (111) or the third conductive area (113).

[0046] A connecting member (120) may be positioned between the housing (110) and the printed circuit board (130). For example, one side of the connecting member (120) may be electrically connected to the housing (110), and the other side of the connecting member (120) may be electrically connected to the printed circuit board (130).

[0047] The connecting member (120) can be attached to the housing (110) through an adhesive material. For example, one side of the connecting member (120) can be attached to the first conductive area (111), and the other side of the connecting member (120) can be attached to the second conductive area (112). Accordingly, the first conductive area (111) can be electrically connected to the second conductive area (112) through the connecting member (120).

[0048] A display panel (140) can be placed between a printed circuit board (130) and a cover glass (150). The display panel (140) is electrically connected to the printed circuit board (130) and can output images such as text, images, videos, icons, widgets, or symbols. If a touch panel is placed on the display panel (140), it can sense touch input from a user.

[0049] The display panel (110) may have a plurality of pixels arranged in a matrix form, and each pixel may consist of subpixels of different colors, for example, a white subpixel, a red subpixel, a green subpixel, and a blue subpixel.

[0050] In the case of a liquid crystal display, the display panel (140) includes a liquid crystal layer formed between two substrates and may operate in any known mode, such as a TN (Twisted Nematic) mode, a VA (Vertical Alignment) mode, an IPS (In Plane Switching) mode, or an FFS (Fringe Field Switching) mode. On the other hand, in the case of an organic light-emitting display, the display panel (140) may be implemented in a top emission method, a bottom emission method, or a dual emission method.

[0051] The communication device (100) of the present invention can improve frequency characteristics by configuring the connecting member (120) connecting the housing (110) and the printed circuit board (130) to enable frequency characteristic control.

[0052] FIG. 2 is a perspective view of a connecting member located between a housing and a printed circuit board in a communication device according to embodiments of the present invention.

[0053] Referring to FIG. 2, in a communication device (100) according to embodiments of the present invention, a connecting member (120) located between a housing (110) and a printed circuit board (130) may include a first electrode (122) electrically connected to the housing (110), a second electrode (126) electrically connected to the printed circuit board (130), and a component part (124) located between the first electrode (122) and the second electrode (126).

[0054] The first electrode (122) is composed of a first external electrode (122a) that contacts the housing (110) and a first internal electrode (122b) that contacts the element part (124), and the first external electrode (122a) and the first internal electrode (122b) are connected to each other and a buffer material (121) that acts as a buffer can be filled between them.

[0055] The second electrode (126) is composed of a second external electrode (126a) that contacts the printed circuit board (120) and a second internal electrode (126b) that contacts the component part (124), and the second external electrode (126a) and the second internal electrode (126b) are connected to each other and a buffer material (127) that acts as a buffer can be filled between them.

[0056] The first electrode (122) and the second electrode (126) may be made of a conductive metal such as copper or a conductive fiber, and the cushioning material (121, 127) filled in the first electrode (122) and the second electrode (126) may be made of a foaming agent such as rubber, vinyl, or polyurethane.

[0057] The component part (124) may be composed of an impedance element consisting of a resistor, a capacitor, or an inductor to control the frequency characteristics of the communication device (100).

[0058] At this time, since the frequency characteristics of the impedance element constituting the element part (124) can be changed depending on the size and structure and the properties of the dielectric placed inside, it can be configured in various ways considering the current transfer characteristics of the communication device (100).

[0059] FIG. 3 is a diagram showing various examples of impedance circuits constituting a component part in a communication device according to embodiments of the present invention.

[0060] Referring to FIG. 3, the element part (124) for controlling frequency characteristics in a communication device (100) according to embodiments of the present invention may be composed of at least one impedance element among a resistor (R), a capacitor (C), and an inductor (L).

[0061] For example, if the wireless signal received through the antenna and the internal signal of the communication device (100) have the same phase and different magnitudes, there is a difference in the resistance (R) component between the impedance of the wireless signal and the impedance of the internal signal, so only a resistance (R) of a certain magnitude can be connected.

[0062] However, when the housing (110) and the printed circuit board (130) are electrically connected, electromagnetic interference (EMI) may be improved as a signal transmission path is formed, but noise may increase in unexpected specific frequency bands.

[0063] As a result, a trade-off phenomenon may occur in which the frequency band at which noise occurs when the housing (110) and the printed circuit board (130) are separated is different from the frequency band at which noise occurs when the housing (110) and the printed circuit board (130) are connected.

[0064] Accordingly, an impedance element can be configured to form a component part (124) so ​​that signal transmission within the communication device (100) is achieved by avoiding a first frequency band in which noise occurs when the housing (110) and the printed circuit board (130) are separated and a second frequency band in which noise occurs when the housing (110) and the printed circuit board (130) are connected.

[0065] For example, an impedance element constituting the element part (124) can be formed by connecting a capacitor (C) and an inductor (L) of a certain size in parallel (Figs. 3(a) to 3(d)).

[0066] Alternatively, the impedance element of the device part (124) may be configured by connecting the capacitor (C) and the inductor (L) in a T structure (Fig. 3(e) and Fig. 3(f)).

[0067] In this way, by configuring the impedance element of the component part (124) constituting the connecting member (120) using a capacitor (C) or an inductor (L), the frequency band in which signal transmission takes place in the communication device (100) can be controlled.

[0068] FIG. 4 is an exemplary diagram showing a signal change according to the configuration of the component part of the connecting member in a communication device according to embodiments of the present invention.

[0069] Referring to FIG. 4, in a communication device (100) according to embodiments of the present invention, the component part (124) of a connecting member (120) located between a housing (110) and a printed circuit board (130) may be configured such that at least one impedance element among a resistor (R), a capacitor (C), and an inductor (L) is connected in series or in parallel.

[0070] At this time, the impedance elements constituting the element section (124) can be arranged in various types and forms, and the resonance frequency of the signal transmitted through the antenna can be changed depending on the type, number, and arrangement of the impedance elements.

[0071] For example, in the case where the component part (124) forming the connecting member (120) is filled only with dielectric material (case 1) and in the case where an impedance element is configured within the component part (124) forming the connecting member (120) (case 2), the resonance frequency and frequency characteristics of the communication circuit (100) may differ.

[0072] As a result, the magnitude of the current and voltage transmitted within the communication circuit (100) may vary according to the frequency band, and the component part (124) of the connecting member (120) can be configured so that signal transmission occurs in a frequency band that avoids the frequency band where noise occurs.

[0073] In this way, when the impedance element configuration of the element part (124) formed in the connecting member (120) is changed, the resonance frequency of the signal transmitted through the antenna and the internal signal can be changed, so the resonance characteristics, i.e., the frequency characteristics of the communication device (100) can be controlled in various ways.

[0074] FIG. 5 is a drawing showing a component part composed of a capacitor in a communication device according to embodiments of the present invention, and FIG. 6 is a drawing showing a connecting member including a component part composed of a capacitor.

[0075] Referring to FIGS. 5 and 6, in a communication device (100) according to embodiments of the present invention, a connecting member (120) located between a housing (110) and a printed circuit board (130) may include a component part (124) composed of a capacitor between a first electrode (122) and a second electrode (126).

[0076] The component part (124) composed of a capacitor may be made of a first conductor (123a) and a second conductor (123b) having an intersecting stacked shape, and a dielectric (125) disposed in the space between the first conductor (123a) and the second conductor (123b).

[0077] The first conductor (123a) may be composed of a plurality of conductive plates that are connected at one end and extended at regular intervals in the first direction (here, the horizontal direction).

[0078] The second conductor (123b) may be composed of a plurality of conductive plates that are connected at one end and extended at regular intervals in the first direction.

[0079] At this time, the first conductor (123a) and the second conductor (123b) may be positioned such that a plurality of conductive plates are arranged facing each other, while forming a certain gap so as not to come into contact.

[0080] A dielectric (125) is placed in the space between the first conductor (123a) and the second conductor (123b). Accordingly, a capacitance can be formed between the first conductor (123a) and the second conductor (123b) that is proportional to the area and number of conductor plates and inversely proportional to the distance between the conductor plates.

[0081] Accordingly, considering the frequency characteristics of the communication device (100), the area of ​​the conductors (123a, 123b) of the component part (124) constituting the connecting member (120), the number of conductive plates, and the distance between the conductive plates may be changed.

[0082] As a result, when the connecting member (124) forms an electrical connection between the housing (110) and the printed circuit board (130), the frequency characteristics of the communication device (100) can be changed by the capacitance formed by the connecting member (124).

[0083] FIG. 7 is a drawing showing a component part composed of an inductor in a communication device according to embodiments of the present invention, and FIG. 8 is a drawing showing a connecting member including a component part composed of an inductor.

[0084] Referring to FIGS. 7 and 8, in a communication device (100) according to embodiments of the present invention, a connecting member (120) located between a housing (110) and a printed circuit board (130) may include a component part (124) in which a plurality of conductive coils (123c) connected in a loop form constitute an inductor.

[0085] The component part (124) constituting the inductor may be formed in a stacked structure in which a plurality of conductive coils (123c) formed in a loop shape share an electrical contact (123d).

[0086] At this time, the conductive coil (123c) may be formed as a single spring shape, or as shown in the drawing, a plurality of separated conductive coils (123c) having a closed-loop shape may be connected through an electrical contact (123d) to form a single integrated connection structure. Alternatively, it may be a structure in which a plurality of separable conductive coils (123c) are connected through an electrical contact (123d) in a certain area.

[0087] In this case, when multiple separated conductive coils (123c) are connected through electrical contacts (123d), the electrical contacts (123d) may be formed at multiple positions symmetrical to each other for a stable structure.

[0088] In the middle region of the conductive coil (123c) forming the loop, a magnetic material such as ferrite may be located as a core, or it may be made of an air core where only air exists without a separate magnetic material.

[0089] In this way, the element part (124) composed of an inductor can form an inductance proportional to the cross-sectional area formed by the conductive coil (123c), the length of the conductive coil (123c), and the number of turns.

[0090] Accordingly, by considering the frequency characteristics of the communication device (100), the frequency characteristics can be controlled by changing the area, length, and number of turns of the conductive coil (123c) located within the component part (124) constituting the connecting member (120).

[0091] As a result, when the connecting member (124) forms an electrical connection between the housing (110) and the printed circuit board (130), the frequency characteristics of the communication device (100) can be changed by the inductance formed by the connecting member (124).

[0092] Meanwhile, the above description was given as an example in which the first electrode (122) of the connecting member (120) is located at the top and the second electrode (126) is located at the bottom, because the housing (110) and the printed circuit board (130) of the communication device (100) are positioned in a vertical direction.

[0093] However, if the housing (110) of the communication device (100) and the printed circuit board (130) are located on the same plane in the horizontal direction, the first electrode (122) and the second electrode (126) may be located on the left and right sides of the connecting member (120), respectively.

[0094] FIG. 9 is a drawing showing a connecting member composed of a capacitor in a communication device according to embodiments of the present invention, where the housing and the printed circuit board are located on the same plane.

[0095] Referring to FIG. 9, in a communication device (100) according to embodiments of the present invention, when a housing (110) and a printed circuit board (130) are located on the same plane, a connecting member (120) may include a first external electrode (122a) positioned to the left for connection with the housing (110), a second external electrode (126a) positioned to the right for connection with the printed circuit board (130), and a component part (124) positioned between the first external electrode (122a) and the second external electrode (126a).

[0096] Here, the positions of the housing (110) and the printed circuit board (130) may be opposite to each other.

[0097] Since the housing (110) and the printed circuit board (130) are located on the same plane, the first external electrode (122a) and the second external electrode (126a) will each extend to the left and right in the same plane and will be electrically in contact with the housing (110) and the printed circuit board (130), respectively.

[0098] At this time, the first external electrode (122a) and the second external electrode (126a) may each include a first internal electrode (122b) and a second internal electrode (126b) that are in contact with the element part (124), and the first internal electrode (122b) and the second internal electrode (126b) may be formed in a region that is in contact with the conductor (123a, 123b) constituting the element part (124).

[0099] Here, a case is illustrated in which the first internal electrode (122b) and the second internal electrode (126b) extend along the lower surface of the element part (124) to form a structure connecting the first external electrode (122a) and the second external electrode (126a).

[0100] Meanwhile, if the housing (110) of the communication device (100) extends from the left side through the lower part of the connecting member (120), an adhesive portion (128) may be provided so that the connecting member (120) can be contacted on one side of the housing (110).

[0101] FIG. 10 is a drawing showing a connecting member composed of an inductor when the housing and the printed circuit board are located on the same plane in a communication device according to embodiments of the present invention.

[0102] Referring to FIG. 10, in a communication device (100) according to embodiments of the present invention, when a housing (110) and a printed circuit board (130) are located on the same plane, a connecting member (120) may include a first external electrode (122a) positioned to the left for connection with the housing (110), a second external electrode (126a) positioned to the right for connection with the printed circuit board (130), and a component part (124) positioned between the first external electrode (122a) and the second external electrode (126a).

[0103] Here, the positions of the housing (110) and the printed circuit board (130) may be opposite to each other.

[0104] Since the housing (110) and the printed circuit board (130) are located on the same plane, the first external electrode (122a) and the second external electrode (126a) will each extend to the left and right in the same plane and will be electrically in contact with the housing (110) and the printed circuit board (130), respectively.

[0105] At this time, the first external electrode (122a) and the second external electrode (126a) may each include a first internal electrode (122b) and a second internal electrode (126b) that are in contact with the element part (124), and the first internal electrode (122b) and the second internal electrode (126b) may be formed to be in contact with a conductive coil (123c) inside the element part (124).

[0106] Here, a case is illustrated in which the first internal electrode (122b) and the second internal electrode (126b) are connected to the first external electrode (122a) and the second external electrode (126a) through a conductive coil (123c) along the right side of the element part (124).

[0107] Meanwhile, if the housing (110) of the communication device (100) extends from the left side through the lower part of the connecting member (120), an adhesive portion (128) may be provided so that the connecting member (120) can be contacted on one side of the housing (110).

[0108] FIG. 11 is a diagram showing an example of controlling frequency characteristics through a connecting member in a communication device according to embodiments of the present invention.

[0109] Referring to FIG. 11, in the communication device (100) according to embodiments of the present invention, a trade-off phenomenon may occur in which the frequency bands where noise occurs differ from each other when the housing (110) and the printed circuit board (130) are electrically separated so that a signal transmission path is not formed, and when the housing (110) and the printed circuit board (130) are directly connected so that a signal transmission path is formed.

[0110] For example, as shown in FIG. 11(a), noise may occur in the band of a first frequency (150 MHz) while the housing (110) and the printed circuit board (130) constituting the communication device (100) are electrically separated.

[0111] In contrast, when the housing (110) and the printed circuit board (130) constituting the communication device (100) are electrically connected, noise may occur in a band of a second frequency (220 MHz) different from the first frequency (150 MHz), as shown in FIG. 11(b).

[0112] In this case, the frequency band that effectively transmits the signal of the communication device (100) while the housing (110) and the printed circuit board (130) are connected through the connecting member (120) may be a band between a first frequency (150 MHz) where noise occurs when the housing (110) and the printed circuit board (130) are electrically separated and a second frequency (220 MHz) where noise occurs when the housing (110) and the printed circuit board (130) are directly connected.

[0113] That is, the component part (124) of the connecting member (120) can be configured to operate as a band-pass filter, with the first frequency (150 MHz) at which noise occurs when the housing (110) and the printed circuit board (130) are electrically separated being a low frequency, and the second frequency (220 MHz) at which noise occurs when the housing (110) and the printed circuit board (130) are directly connected being a high frequency.

[0114] In this case, the electromagnetic interference formed between the housing (110) and the printed circuit board (130) can be effectively improved by configuring the frequency characteristics of the connecting member (120) so that the signal transmission of the communication device (100) is centered on 180 to 190 MHz, which corresponds to an intermediate frequency between 150 MHz and 220 MHz, so that signal transmission can be achieved in a frequency band between 150 MHz and 220 MHz.

[0115] Meanwhile, the above description was given as an example where the connecting member (120) connects the housing (110) and the printed circuit board (130), but the upper housing and the lower housing constituting the communication device (100) may also be connected by the connecting member (120). In this case, even when the connecting member (120) comes into contact with the conductive regions (111, 112, 113) of the upper housing and the lower housing, the frequency characteristics of the communication device (100) can be controlled through a capacitor or inductor configuration, just as described above.

[0116] The foregoing description is merely an illustrative explanation of the technical concept of the present invention, and those skilled in the art to which the present invention pertains will be able to make various modifications and variations within the scope of the essential characteristics of the present invention. Furthermore, the embodiments disclosed in the present invention are intended to explain, not limit, the technical concept of the present invention, and thus the scope of the technical concept of the present invention is not limited by these embodiments. The scope of protection of the present invention shall be interpreted by the claims below, and all technical concepts within an equivalent scope shall be interpreted as being included within the scope of rights of the present invention.
