    Description

    TECHNICAL FIELD



    [0001] The described embodiments relate to electronic devices, and in particular to an electronic device with advanced antenna.

    BACKGROUND



    [0002] The screen-to-body ratio of electronic devices such as mobile phone and laptop has become higher and higher such that space for the clearance area of antenna has become more and more limited. In a bezel-less electronic device, the clearance area of antenna is very limited. As known, the display screen may influence the performance of the antenna. Thus, how to reduce the influence of the display screen to the antenna is an important factor during the design of electronic devices, especially for those having bezel-less screen.

    [0003] An electronic device according to the preamble of claim 1 is known from US 2017/302771 A1. Further prior art is disclosed in WO 2017/156900 A1, CN 104 935 695 A, and US 2016/233573 A1.

    SUMMARY



    [0004] It is an object of the invention to provide an electronic device comprising an antenna, in which the influence of a display screen on the antenna is reduced and at the same time the strength of the outer cast of the electronic device is increased. The object is satisfied by the subject matter of claim 1.

    [0005] The present disclosure provides an electronic device in order to solve the influence of the display screen to the antenna included in the electronic device.

    [0006] In a first aspect of the present disclosure, an electronic device with antenna is provided. The electronic device may include: a display screen which includes a display panel and a touch-control panel; a metal frame surrounding a side edge of the display screen, wherein at least a part of the metal frame is configured as antenna radiator; and a connecting component disposed between the side edge of the display screen and a top end of the metal frame, wherein the connecting component comprises insulating material.. There is an overlap of height between the side edge of the display screen and the metal frame along an axis perpendicular to an upper surface of the display screen. A height of the connecting component along the axis perpendicular to an upper surface the display screen is larger than a first predetermined value, and the height of the overlap is less than a second predetermined value, such that the influence of the display screen on performance of the metal frame configured as the antenna radiator is reduced or eliminated.

    [0007] Since the height of the connecting component is larger than the preset height such that the area of the portion of the side edge of the display screen which faces directly the metal frame may be smaller than a predetermined value. Thus, interruption between the display screen and the metal frame may be reduced or eliminated.

    DETAILED DESCRIPTION



    [0009] The disclosure will now be described in detail with reference to the accompanying drawings and examples. Apparently, the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. The invention is set out in the independent claims.

    [0010] In the specification, it is to be understood that terms such as "thickness" should be construed to refer to the orientation as then described or as shown in the drawings under discussion. These relative terms are for convenience of description and do not require that the present disclosure be constructed or operated in a particular orientation. In addition, terms such as "first" and "second" are used herein for purposes of description and are not intended to indicate or imply relative importance or significance or to imply the number of indicated technical features.

    [0011] Referring to FIGs. 1 and 2, FIG. 1 is a top view of an electronic device 100, which shows the front-side structure of the electronic device 100, and FIG. 2 is a section view of the electronic device 100 taken along the line I-I and shows some of the components inside. The electronic device 100 includes a display screen 11, a metal frame 12 arranged surrounding the side edge S1 of the display screen 11, and a connecting component 13 located between the side edge S1 of the display screen 11 and the top end of the metal frame 12. The height of the connecting component 13 is larger than a preset height, such that the portion of the side edge S1 of the display screen 11 which does not face directly the metal frame 12 has at least the preset height.

    [0012] As shown in FIG. 2, the top end of the metal frame 12 and the side edge S1 of the display screen 11 may be substantially perpendicular, and form a step. The connecting component 13 may be set at the position of the step such that the outer surface of the electronic device may be smooth and continuous. Since the height of the connecting component 13 is larger than the preset height, the area of the portion of the side edge S1 of the display screen 11 which faces directly the metal frame 12 is less than a predetermined value. Thus, interruption between the display screen 11 and the metal frame 12 is reduced or eliminated.

    [0013] In some embodiments, the top portion of the connecting component 13 may be substantially flush with the upper surface 111 of the display screen 11. The bottom portion of the connecting component 13 may abut the top end of the metal frame 12. In this circumstance, the thicker the connecting component 13 is, the farther the top end of the metal frame 12 is away from the upper surface 111 of the display screen 11. In other words, the height H1 of an overlap between the side edge S1 of the display screen 11 and the metal frame 12 is smaller. Accordingly, the area of the portion of the side edge S1 of the display screen 11 which faces directly the metal frame 12 is smaller.

    [0014] The upper surface 111 may refer to the surface of the display screen 11 close to the front-side of the electronic device 100. The top end of the metal frame 12 may refer to the end of the metal frame 12 close to the front-side of the electronic device 100.

    [0015] According to the invention, at least a portion of the metal frame 12 is configured as antenna radiator for transmitting and receiving signals. The preset height may be determined based on actual requirement. Specifically, the value of the preset height satisfies that the influence of the display screen 11 to the metal frame 12 configured as the antenna radiator is less than a predetermined value. That is, when the height of the connecting component 13 is larger than the preset height, the portion of the display screen 11 which faces directly the metal frame 12 is small enough to make the influence of the display screen 11 to the metal frame 11 configured as antenna radiator to be less than the predetermined value.

    [0016] In some embodiments, the predetermined value of the influence may be, for example but not limited to, 1/10 or 1/8 of the maximal radiation power of the antenna.

    [0017] As shown in FIG. 2, the electronic device 100 may further include a cover plate 14. The cover plate 14 may cover the display screen 11 and be utilized to protect the display screen 11. The size of the cover plate 14 may be larger than the display screen 11. The cover plate 14 may extend outside the display screen 11 in the extending direction of the display screen 11.

    [0018] As shown in FIG. 2, part of the top portion of the connecting component 13 may be located under the cover plate 14. such that the connecting component 13 may be embedded between the cover plate 14 and the metal frame 12.

    [0019] In some embodiments, the cover plate 14 may be a glass cover plate.

    [0020] In some embodiments, the connecting component 13 may be made of insulating material such as plastic and ceramic.

    [0021] As shown in FIG. 2, the top portion of the connecting component 13 may include a fitting portion B1 and a protrusion portion B2. The fitting portion B1 may be the part of the top portion of the connecting component 13 located under the cover plate 14. The fitting portion B1 may be clung to the cover plate 14. The fitting portion B1 may be substantially flush with the upper surface 111 of the display screen 11. The protrusion portion B2 may extend from the fitting portion B1 to the side edge of the cover plate 14, and may cover the side edge of the cover plate 14. The height from the fitting portion B1 to the bottom portion of the connecting component 13 may be larger than the preset height, such that the portion of the side edge S1 of the display screen 11 which does not face directly the metal frame 12 may have at least the preset height.

    [0022] In some embodiments, the protrusion portion B2 may extend to be substantially flush with the upper surface of the cover plate 14. The outer surface W1 of the protrusion portion B2 may be smoothly connected to the outer surface W2 of the metal frame 12 and the upper surface 141 of the cover plate 14. That is, the cover plate 14 and the metal frame 12 of the electronic device 100 may be smoothly connected to present an integral structure. There is no gap between the metal frame 12 and the cover plate 14.

    [0023] It should be understood that, not all the components of the electronic devices 100 are shown in FIG. 2. Various components such as the back case are omitted for simplicity and clarity.

    [0024] Referring to FIG. 3, FIG. 3 is a side view of the display screen 11. According to the invention, the display screen 11 may be a touch-control display screen which includes a display panel 111 and a touch-control panel 112 covering the display panel 111.

    [0025] The display panel 11 may be utilized to display images while the touch-control panel 112 may be utilized for user input and human-machine interaction.

    [0026] Referring also to FIG. 4, FG. 4 is a section view of the electronic device shown in FIG. 1 taken along the line I-I according to another embodiment of the present disclosure. According to the invention, the display screen 11 includes a display panel 111 and a touch-control panel 112.

    [0027] As shown in FIG. 4, in some embodiments, the connecting component 13 may be the touch panel frame which covering closely the side edge of the touch-control panel 112. In this embodiment, the connecting component 13 may also cover part of the side edge of the display panel 111.

    [0028] In some embodiments, the connecting component 13 used as the touch panel frame may only cover the side edge of the touch-control panel 112. In this situation, the whole side edge of the display panel 111 may directly face the metal frame 12. In other embodiments of the present disclosure, the connecting component 13 may cover at least part of the side edge of the display panel 111 such that the location of the metal frame 12 may be lower, i.e., the area of the portion of the side edge S1 of the display screen 11 (including the display panel 111 and the touch-control panel 112) which faces directly the metal frame 12 may be smaller. Thus, the influence of the display screen 11 to the performance of the metal frame 12 used as antenna radiator may be reduced.

    [0029] In some embodiments, the connecting component 13 may cover 1/3 of the thickness of the side edge of the display panel 111. It should be understood that, in other embodiments, this ratio may be determined properly based on actual requirement. For example, the connecting component 13 may alternatively cover 2/5 of the thickness of the side edge of the display panel 111.

    [0030] Referring to FIG. 2 or FIG. 4, in some embodiments, the electronic device 100 may further include a support frame 15. The support frame 15 may support the display screen 11.

    [0031] There may exist a gap between the metal frame 12 and the side edge S1 of the display screen 11. The distance between the support frame 15 and the metal frame 12 may be less than the distance between the metal frame 12 and the side edge S1 of the display screen 11.

    [0032] Specifically, as shown in FIG. 2 or FIG. 4, the support frame 15 may be clung to the metal frame 12. The display screen 11 may be disposed on the support frame 15. The side edge S1 of the display screen 11 and the edge of the metal frame 12 which abuts the support frame 15 may be spaced apart by a preset distance. That is, the side edge S 1 of the display screen 11 may be spaced apart from the metal frame 12 by the preset distance.

    [0033] The support frame 15 may be made of insulating material such as plastic.

    [0034] Referring also to FIG. 5, FIG. 5 is a top view of a metal frame 12 according to an embodiment of the present disclosure. In some embodiments, the metal frame 12 may be a closed frame surrounding four side edges S1 of the display screen 11.

    [0035] The metal frame 12 may define at least one spacing portion 121. The spacing portion 121 may divide the metal frame 12 into at least one independent frame-body 122.

    [0036] As shown in FIG. 3, the electronic device 100 may further include a radio frequency (RF) circuit 20. Each independent frame-body 122 may be utilized as an independent antenna radiator, and may be connected to a respective RF circuit 20 to transmit or receive signals in a same frequency range or different frequency ranges.

    [0037] As shown in FIG. 5, the number of the spacing portions 121 may be two. In this situation, the metal frame 12 may be divided into two independent frame-bodies 122 which may be utilized as antenna radiator. Accordingly, there may be two RF circuits 20, and the two RF circuits 20 may be utilized to generate signals in different frequency ranges. The two RF circuits 20 may electrically connect to the two frame-bodies 122 respectively. Therefore, each frame-body 122 may be utilized as the antenna radiator of a respective RF circuit 20 and to transmit and receive signals in the respective frequency range.

    [0038] In some embodiments, the spacing portion 121 may be a micro-seam band. As shown in FIG. 5, the spacing portion 121 may include at least two micro-seams F1 spaced apart. A metal strip J1 may be disposed between the two micro-seams F1. The length direction of the metal strip J1 (i.e., the extending direction of the metal strip J1) and the width direction of the metal frame 12 (i.e., the direction from the top end to the bottom end) may be parallel.

    [0039] The width of the spacing portion 121 may be 1.5 mm, 5.0 mm or range from 1.5 mm to 5.0 mm. The width of the micro-seam F1 may be 0.05 mm, 0.3 mm or range from 0.05 mm to 0.3 mm. The micro-seam F1 may be filled with signal shielding material, such as insulating material (e.g., plastic). The width of the metal strip J1 may be 0.1 mm, 0.5 mm or range from 0.1 mm to 0.5 mm.

    [0040] The two RF circuits 20 may be any two of GSM (global system for mobile communication) RF circuit, CDMA (code division multiple access) RF circuit, Bluetooth RF circuit, WIFI RF circuit or NFC RF circuit.

    [0041] In some embodiments, all the frame-bodies 122 of the metal frame 12 may be utilized as antenna radiators and may be connected with the corresponding RF circuits 20. In this circumstance, the four side edges S1 of the display screen 11 may be spaced apart from the metal frame 12 by a preset distance.

    [0042] Referring to FIG. 6, FIG. 6 is a top view of a metal frame 12 according to an embodiment of the present disclosure. In this embodiment, there may be four spacing portions 121, such that the metal frame 12 may be divided into four independent frame-bodies 122. The frame-body 122a and the frame-body 122c may be respectively located at two opposite first side edges, and the frame-body 122b and the frame-body 122d may be respectively located at two opposite second side edges. In this embodiment, the electronic device 100 may be of a rectangular shape including four side edges. The metal frame 12 may be utilized as the side frame of the electronic device 100 and also have four side edges. As shown in FIG. 6, the four spacing portions 121 may be located close to the four corners of the metal frame 12.

    [0043] In this embodiment, the frame-bodies 122a and 122c located respectively at the two opposite first side edges are utilized as antenna radiators. The number of the RF circuits 20 may be two. The two RF circuits 20 may be configured to generate signals in different frequency ranges. The two RF circuits 20 may electrically connect to the two frame-bodies 122a and 122c located at the two opposite first side edges respectively. Thus, the frame-bodies 122a and 122c located at the two opposite first side edges may be used as antenna radiators for different RF circuits 20, and to transmit and receive signals in different frequency ranges.

    [0044] Referring to FIG. 7, FIG. 7 illustrates the position relation between a metal frame 12, a display screen 11 and a support frame 15 according to an embodiment of the present disclosure.

    [0045] In some embodiments, the two frame-bodies 122 located at the two opposite first side edges of the metal frame 12 are utilized as antenna radiators of RF circuits 20. The side edges S1 of the display screen 11 facing the two frame-bodies 122 configured as antenna radiator may be spaced apart from the frame-bodies 122 by a first preset distance. The other side edges S1 of the display screen 11 which does not face the frame-bodies 122 configured as antenna radiators may be spaced apart from the from the frame-bodies 122 by a second preset distance. The second preset distance may be smaller than the first preset distance. For example, the first preset distance may be 5 mm, and the second preset distance may be 2 mm. Thus, the bezel-less effect may be achieved in the premise that the performance of the frame-bodies of the metal frame 12 configured as antenna radiators is not influenced by the display screen 11. In some embodiments, the side edges S1 of the display screen 11 which face the frame-bodies 122 not utilized as antenna radiators may be clung to the frame-bodies 122 not utilized as antenna radiators. Therefore, bezel-less effect may be achieved.

    [0046] In some embodiments, the two opposite first side edges may be the two short edges, and the two opposite second edges may be the two long edges.

    [0047] The two RF circuits 20 may be any two of GSM (global system for mobile communication) RF circuit, CDMA (code division multiple access) RF circuit, Bluetooth RF circuit, WIFI RF circuit or NFC RF circuit.

    [0048] It should be understood that, the RF circuits 20 may include a RF transmitting and receiving circuit and corresponding auxiliary circuits.

    [0049] The spacing portion 121 may be a micro-seam band. The spacing portion 121 may include at least two micro-seams F1 spaced apart. A metal strip J1 may be disposed between the two micro-seams F1. The length direction of the metal strip J1 (i.e., the extending direction of the metal strip J1) and the width direction of the metal frame 12 (i.e., the direction from the top end to the bottom end) may be parallel.

    [0050] The width of the spacing portion 121 may be 1.5 mm, 5.0 mm or range from 1.5 mm to 5.0 mm. The width of the micro-seam F1 may be 0.05 mm, 0.3 00 or range from 0.05 mm to 0.3 mm. The micro-seam F1 may be filled with signal shielding material, such as insulating material (e.g., plastic). The width of the metal strip J1 may be 0.1 mm, 0.5 mm or range from 0.1 mm to 0.5 mm.

    [0051] The electronic device 100 may be a cell phone, a laptop and the like.

    [0052] In the electronic device 100 of the present disclosure, the metal frame 12 may be utilized as antenna radiator. The performance of antenna may be improved. Since the area of the display screen 11 facing directly the metal frame 12 is reduced, the influence of the display screen 11 to the performance of the metal frame 12. Thus, the performance of the metal frame 12 as antenna radiator may be improved. The embodiments in the description which are not covered by the claims are useful for understanding the invention and highlighting specific aspects of the invention.

    [0053] Any embodiment that is not covered by the claims does not form a part of the present invention and is described for understanding the present invention.
