A second back film layer 6 is disposed on a side of the binding part 1c facing the display part 1a. A support layer 7, a copper foil layer 8, and a foam layer 9, etc. can be disposed between the first back film layer 5 and the second back film layer 6. A first insulating layer 10, an electromagnetic interference tape (EMI Tape) 11, and a second insulating layer 12 are disposed on a side of the binding part 1c facing away from the display part 1a. The thickness of the bending part 1b is small (on the order of 0.0xx millimeters). The bending part 1b is a bare area and is easily damaged by electrostatic breakdown.
[0086] The related art can cover a module coating layer (MCL) 13 on an outer side of the bending part 1b, a partial area of the display part 1a, and a partial area of the binding part 1c. One end of the EMI Tape 11, which is grounded, can be lapped on the MCL 13 to achieve a grounding effect. External static electricity is guided along the MCL 13 and the EMI Tape 11 (as shown by the arrows in FIG. 1), thereby reducing damage to the display module 1 caused by external static electricity.
[0087] In the left-right direction shown in FIG. 1, the distance from a vertex O (a vertex of an arc on a side of the MCL 13 facing away from the bending part 1b) to a connecting end surface of the MCL 13 on the display part 1a is defined as A, and the distance from the vertex O to a lapped end surface of the EMI Tape 11 is defined as B. In the case where B is less than A, external static electricity can be guided along the MCL 13 and the EMI Tape 11 (as shown by the arrows in FIG. 1), thereby achieving the purpose of static electricity release. In the case where B is greater than A, external static electricity will be guided along the MCL 13 toward the side of the display part 1a, which can cause damage to the display part 1a.
[0088] In the manufacturing process of the display module 1 in the related art, the EMI Tape 11 and the MCL 13 are prone to poor lapping. The lapping tolerance of the EMI Tape fixture is large (up to ±0.8 millimeters). These factors can make it difficult to meet the requirement that B is less than A, and the bending part 1b of the display module 1 is prone to damage caused by electrostatic breakdown. Typically, the manufacturer of the display module 1 sets the anti-static capability of the display module 1 to about 6 kilovolts (kV). In order to ensure the high reliability of the anti-static capability of the entire electronic device, the anti-static capability of the entire electronic device can be set to 10 kV.
[0089] It is difficult to achieve the anti-static ability of 10kV of the whole electronic device by using the protection glue 13 and the conductive cloth 11 overlapping scheme. On the basis of the protection glue 13 and the conductive cloth 11 overlapping scheme, in combination with FIG. 2 and FIG. 3, the conductive silver paste 16 is screen printed on the inner surface of the frame 15 corresponding to the bending part 1b of the display module 1 to form a screen printing area, and the grounding point of the middle frame 14 is provided with a laser etching area (not shown in the figure), so that the screen printing area and the laser etching area are directly connected or gap coupled, the external static electricity is guided to the middle frame 14, and the static electricity is released.
[0090] However, the conductive silver paste 16 is a composite material of metal particles and glue, the conductivity of the conductive silver paste 16 is low, the impedance of the conductive silver paste 16 is high (tens to hundreds of ohms), the conductive silver paste 16 will absorb the antenna energy to cause the antenna performance to be poor, and it is not conducive to densely arranging the antennas (not shown in the figure) on the circuit board (not shown in the figure) corresponding to the bending part 1b of the display module 1. If the antennas are arranged on the circuit board corresponding to the bending part 1b of the display module 1, the conductive silver paste 16 is a suspended metal relative to these antennas, and the more the number of antennas, the more grounding points are needed. If a small number of parasitic antennas are arranged on the circuit board corresponding to the bending part 1b of the display module 1, the antenna grounding points need to be arranged, and the circuit board and the middle frame 14 can be electrically connected through the spring piece. Moreover, the conductive silver paste 16 is screen printed on the inner surface of the frame 15 to form a screen printing area, and the screen printing area and the laser etching area are directly connected by smearing the conductive silver paste, and the cost of these processes is relatively high.
[0091] The electronic device provided in the embodiments of the present application can be a mobile phone, a tablet computer, a notebook computer, an e-book reader, a netbook, a personal digital assistant, a smart wearable device (such as a smart watch), etc. The mobile phone can be a folding machine, a side sliding machine or a straight board machine, etc. The following mainly takes the electronic device as a folding machine as an example for description.
[0092] Referring to FIG. 4 to FIG. 8, the electronic device 1000 provided in the embodiments of the present application comprises a first main body 100, a first display module 200, a first frame 100a, a metal layer 300 and an elastic conductive piece 400. The first display module 200 is arranged on one side of the first main body 100, and the first display module 200 has a bending part 220 located at the edge of the first main body 100. The first frame 100a is arranged on the first main body 100, and the first frame 100a is located at the edge of the first display module 200 corresponding to the first main body 100. The inner surface 100b of the first frame 100a corresponding to the bending part 220 is provided with the metal layer 300. The elastic conductive piece 400 is mounted on the first main body 100, and the elastic conductive piece 400 is electrically connected with the first main body 100. The elastic conductive piece 400 has a spring contact part 400a abutting against the metal layer 300. The edge of the first main body 100 is provided with an antenna 500, and at least part of the antenna 500 is arranged adjacent to the metal layer 300.
[0093] The first main body 100 can serve as a carrier for mounting devices such as the first display module 200, a circuit board, a battery, and the like. The first main body 100 can serve as a large area of the electronic device 1000. The first main body 100 can include a middle frame.
[0094] The first display module 200 can be configured to display images and information. The first display module 200 can include a display portion 210, a bending portion 220, and a binding portion 230. One end of the bending portion 220 is connected to an edge of the display portion 210, and the other end of the bending portion 220 is connected to the binding portion 230. The display portion 210 and the binding portion 230 are electrically connected through the bending portion 220. The binding portion 230 is disposed on the back of the display portion 210. A touch layer can be disposed in the first display module 200 to implement a touch function.
[0095] The first bezel 100a can shield and protect the edge of the first display module 200, thereby reducing damage to the edge of the first display module 200. The inner surface 100b of the first bezel 100a refers to a surface of the first bezel 100a that faces the first display module 200.
[0096] The electrical connection between the elastic conductive member 400 and the first main body 100 refers to the electrical connection between the elastic conductive member 400 and a large area of the first main body 100.
[0097] The antenna 500 at the edge of the first main body 100 can be disposed on a circuit board of the first main body 100, and can also be disposed in an edge region of the first main body 100.
[0098] The electronic device 1000 provided by the embodiments of the present application includes the first display module 200 and the first bezel 100a on the first main body 100. The first bezel 100a is located at the edge of the first display module 200. The inner surface 100b of the first bezel 100a corresponding to the bending portion 220 of the first display module 200 is provided with a metal layer 300. The elastic connecting portion 400a of the elastic conductive member 400 on the first main body 100 abuts against the metal layer 300. The metal layer 300 can be understood as a pure metal material. The metal layer 300 has a large electrical conductivity and a small impedance, and has a small absorption of antenna energy. External static electricity can be guided to the first main body 100 through the metal layer 300 and the elastic conductive member 400, thereby effectively releasing static electricity and improving the anti-static capability (e.g., greater than or equal to 10 kV) of the entire electronic device 1000. The antenna 500 on the first main body 100 is disposed adjacent to the metal layer 300. The metal layer 300 and the antenna 500 are coupled. The metal layer 300 serves as part of an antenna radiator to promote radiation, which is conducive to densely arranging antennas at positions corresponding to the bending portion 220 of the first display module 200. In the related art, a conductive silver paste is arranged on the inner surface of the bezel corresponding to the bending portion of the display module. The conductive silver paste absorbs antenna energy, which leads to poor performance of the antenna.
[0099] In some embodiments, referring to FIGS. 4-6, the electronic device 1000 is a folding machine, and the electronic device 1000 further includes a second body 600 hinged with the first body 100. The first body 100 and the second body 600 can rotate relative to each other to switch between a flat state and a closed state. One end of the first body 100 and one end of the second body 600 are both hinged on the rotating shaft assembly 700 to realize the rotating movement of the first body 100 and the second body 600 relative to the rotating shaft assembly 700, respectively.
[0100] The first display module 200 is a flexible screen, and the display part 210 of the flexible screen has a first fixed area 211, a bending area 212, and a second fixed area 213 connected in sequence. The first fixed area 211 is fixed on the first body 100, the second fixed area 213 is fixed on the second body 600, and the bending area 212 is correspondingly arranged with the rotating shaft assembly 700. The first fixed area 211 and the first body 100, and the second fixed area 213 and the second body 600 can be connected by colloid bonding or other means.
[0101] During the opening and closing movement of the first body 100 and the second body 600, the first display module 200 follows the opening and closing movement of the first body 100 and the second body 600. As shown in FIG. 4, in the flat state of the folding machine, the size of the flat flexible screen is large, and the user has a good viewing experience. As shown in FIG. 5, in the closed state of the folding machine, the structure is compact and convenient to carry.
[0102] In some embodiments, referring to FIGS. 4 and 6, the second body 600 is provided with a second frame 600a, and the second frame 600a is located at the edge of the first display module 200 corresponding to the second body 600. The second frame 600a can shield and protect the edge of the first display module 200, reducing damage to the edge of the first display module 200.
[0103] For example, the flat state of the flexible screen can be substantially a circular rectangular, and the outer shape of the first body 100 and the second body 600 can be substantially a plate-shaped cuboid. The first frame 100a and the second frame 600a can both be substantially a right-angle U-shaped extension, and the cross-sectional shape of the first frame 100a and the second frame 600a perpendicular to the extension direction can be substantially an L-shaped. The opening of the first frame 100a and the opening of the second frame 600a are arranged to face each other. The first frame 100a and the second frame 600a are respectively arranged corresponding to different edges of the flexible screen to shield and protect the corresponding edge positions of the flexible screen.
[0104] To reliably abut the metal layer 300 on the first side frame 100a and the elastic conductive piece 400, in some embodiments, referring to FIG. 9 and FIG. 10, the first side frame 100a includes a first side 110 and a second side 120 connected to each other, the first side 110 is arranged to face the display surface 200a of the first display module 200, the second side 120 is arranged to face the side surface 200b of the first display module 200, and the second side 120 is fixed to the first main body 100. In combination with FIG. 8 and FIG. 11, the metal layer 300 includes a first metal part 310 and a second metal part 320, the first metal part 310 is arranged on the inner surface 110a of the first side 110, the second metal part 320 is arranged on the inner surface 120a of the second side 120, and the first metal part 310 and the second metal part 320 are connected to each other. The elastic contact part 400a is arranged to abut against the second metal part 320.
[0105] In combination with FIG. 8, the inner surface 110a of the first side 110 refers to the side of the first side 110 facing the display surface 200a of the first display module 200. The inner surface 120a of the second side 120 refers to the side of the second side 120 facing the side surface 200b of the first display module 200. The display surface 200a of the first display module 200 is the side of the first display module 200 from which light is emitted, and the display surface 200a can include a display area and a non-display area located at the edge of the display area. The side surface 200b of the first display module 200 is the peripheral surface adjacent to the display surface 200a.
[0106] The first side 110 and the second side 120 can be arranged perpendicularly. It is also possible to consider that the second side 120 has a mold draft angle of 3° or less.
[0107] The first side frame 100a is easy to assemble on the first main body 100 and can shield and protect the edge of the first display module 200. The first metal part 310 on the first side 110 and the second metal part 320 on the second side 120 are connected to each other, and the elastic contact part 400a of the elastic conductive piece 400 is arranged to abut against the second side 120, so that the metal layer 300 on the first side frame 100a and the elastic conductive piece 400 are reliably abutted. External static electricity can be guided to the first main body 100 through the first metal part 310, the second metal part 320, and the elastic conductive piece 400, so that the static electricity is effectively released, and the anti-static capability of the entire electronic device 1000 is improved. The elastic conductive piece 400 is prevented from abutting against the metal layer 300 in the thickness direction of the first main body 100, so that the first side frame 100a is prevented from being assembled to arch and fall off in the thickness direction of the first main body 100 (the up-down direction in FIG. 8), and the problem of unstable electrical connection caused by the large-area coupling between the metal layer 300 and the elastic conductive piece 400 is avoided.
[0108] Exemplarily, referring to FIG. 11, the inner surface 110a of the first side edge 110 corresponding to the bending part 220 of the first display module 200 is provided with a first metal part 310, and the inner surface 120a of the second side edge 120 is provided with a plurality of second metal parts 320. The plurality of second metal parts 320 are arranged in sequence along the extension direction of the second side edge 120. The first metal part 310 is connected with the plurality of second metal parts 320.
[0109] Exemplarily, referring to FIG. 11, the inner surface 110a of the first side edge 110 corresponding to the bending part 220 of the first display module 200 is provided with a plurality of first metal parts 310, and the plurality of first metal parts 310 are arranged in sequence along the extension direction of the first side edge 110. The plurality of second metal parts 320 are arranged in sequence along the extension direction of the second side edge 120. Each first metal part 310 is connected with one or more second metal parts 320.
[0110] When assembling the first frame 100a and the first main body 100, referring to FIG. 9 and FIG. 10, the edge of the first main body 100 has a slot 101, and the second side edge 120 is inserted into the slot 101. By inserting the second side edge 120 into the slot 101 of the first main body 100, the first frame 100a can be reliably connected to the first main body 100. The second metal part 320 on the second side edge 120 and the elastic contact part 400a of the elastic conductive part 400 can be in reliable abutment, so that they can be reliably electrically connected, realizing electrostatic guiding and releasing. The second side edge 120 and the inner wall of the slot 101 can be bonded by a colloid.
[0111] When setting the second side edge 120 and the second metal part 320 of the first frame 100a, referring to FIG. 8 and FIG. 11, the second side edge 120 has a pin 121 extending along the thickness direction (the up-down direction of FIG. 8) of the first main body 100, the pin 121 is inserted into the first main body 100, and the inner surface of the pin 121 is provided with the second metal part 320; the elastic contact part 400a is abutted against the second metal part 320 at the pin 121.
[0112] The pin 121 of the second side edge 120 is inserted into the first main body 100, so that the second side edge 120 can be reliably connected to the first main body 100. The elastic contact part 400a of the elastic conductive part 400 is abutted against the second metal part 320 on the inner surface of the pin 121, which increases the distance between the elastic conductive part 400 and the bending part 220 of the first display module 200, and reduces the influence of the elastic conductive part 400 on the bending part 220.
[0113] Exemplarily, the second side edge 120 has a plurality of spaced-apart pins 121, and the inner surface of each pin 121 in the region of the bending portion 220 is provided with a second metal portion 320. The elastic contact portion 400a of each elastic conductive member 400 corresponds to and abuts against the second metal portion 320 of the inner surface of the corresponding pin 121, thereby improving the reliability of the electrostatic discharge path.
[0114] In order to make the first main body 100 with the elastic conductive member 400 compact, in some embodiments, referring to FIG. 8, in the thickness direction of the first main body 100, the bending portion 220 is located between the first side edge 110 and the elastic conductive member 400. The thickness direction of the first main body 100 is the thickness direction of the first display module 200.
[0115] Arranging the elastic conductive member 400 at a position away from the first side edge 110 of the bending portion 220 effectively utilizes the space in the thickness direction of the first main body 100, so that the first main body 100 with the elastic conductive member 400 is compact and occupies less space.
[0116] When the metal layer 300 is provided, referring to FIG. 8, the metal layer 300 includes at least one of a laser ablation metal layer, a laser direct structuring metal layer, a laser restructuring printing metal layer, and a laser structuring coating metal layer. The material of the metal layer 300 can be silver, gold, nickel, or stainless steel, etc.
[0117] The laser ablation metal layer is made by laser activating plating (LAP). A pattern is engraved on the surface of a workpiece by laser, the pattern area is activated by chemical reagent, and the pattern area is metallized by chemical plating.
[0118] The laser direct structuring metal layer is made by laser direct structuring (LDS). A pattern is engraved on the surface of a workpiece by laser, the surface of the pattern area is activated, and the pattern area is metallized by chemical plating.
[0119] The laser restructuring printing metal layer is made by laser restructuring printing (LRP). A metal material is coated on the surface of a workpiece by three-dimensional printing process, and a predetermined pattern of metal area is formed by three-dimensional laser trimming.
[0120] The laser structuring coating metal layer is made by laser structuring coating (LSC). A powder metal material is coated on the surface of a workpiece, and a predetermined pattern of metal area is formed on the surface of the workpiece by laser melting the metal material and the surface layer of the workpiece.
[0121] The metal layer 300 can be selected as required. The metal layer 300 is easily attached to the inner surface 100b of the first frame 100a, and the connection is reliable and stable. The metal layer 300 can be understood as a pure metal material. The metal layer 300 has a large electrical conductivity and a small impedance, and has a small absorption of antenna energy.
[0122] The metal layer 300 on the first frame 100a, in combination with the elastic conductive part 400 of the first body 100, can achieve static electricity guiding and releasing, and improve the anti-static capability of the electronic device 1000. The antenna 500 on the first body 100 is arranged adjacent to the metal layer 300. The metal layer 300 and the antenna 500 are coupled. The metal layer 300 promotes radiation as part of the antenna radiator, and is conducive to densely arranging the antenna at a position corresponding to the bending part 220 of the first display module 200. Compared with the related art of arranging conductive silver paste on the inner surface of the frame, the embodiment arranges the metal layer 300 on the inner surface 100b of the first frame 100a, which has a low cost.
[0123] When measuring the impedance of the metal layer 300, the impedance of the metal layer 300 between the two ends in the extension direction of the first frame 100a is less than or equal to 1 ohm (Ω). An ohmmeter can be used to measure the impedance of the metal layer 300 at the two ends in the extension direction of the first frame 100a. The metal layer 300 can be understood as a pure metal material, and has a small absorption of antenna energy. External static electricity can be guided to the first body 100 through the metal layer 300 and the elastic conductive part 400, to achieve effective release of static electricity, and to improve the anti-static capability of the entire electronic device 1000 (e.g., greater than or equal to 10 kV).
[0124] For example, the impedance of the metal layer 300 between the two ends in the extension direction of the first frame 100a is less than or equal to 0.5 ohm.
[0125] When comparing the metal layer 300 and the conductive silver paste, the conductive silver paste is a composite material of metal particles and glue, and the metal layer 300 is a pure metal material. The electrical conductivity of the metal layer 300 is greater than that of the conductive silver paste, and the square resistance of the metal layer 300 is smaller than that of the conductive silver paste.
[0126] The related art arranges the conductive silver paste on the inner surface of the frame. When the conductive silver paste is arranged adjacent to the antenna, the conductive silver paste will absorb antenna energy, which will cause the antenna performance to deteriorate, and is not conducive to densely arranging the antenna at a position corresponding to the bending part of the display module.
[0127] In the embodiment, the metal layer 300 is arranged on the inner surface of the first frame. The antenna 500 on the first body 100 is arranged adjacent to the metal layer 300. The metal layer 300 has a small absorption of antenna energy. The metal layer 300 and the antenna 500 are coupled. The metal layer 300 promotes radiation as part of the antenna radiator, and is conducive to densely arranging the antenna at a position corresponding to the bending part 220 of the first display module 200.
[0128] To facilitate the installation of the elastic conductive part 400 on the first main body 100, in some embodiments, referring to FIG. 8, FIG. 10, and FIG. 12, the first main body 100 is provided with a limiting groove 102 near the first frame 100a, and the elastic conductive part 400 is embedded in the limiting groove 102. This facilitates the positioning and assembly of the elastic conductive part 400 at a predetermined position of the first main body 100, improving assembly efficiency. The metal layer 300 of the first frame 100a and the elastic contact part 400a of the elastic conductive part 400 can be reliably abutted, improving the reliability of the electrostatic discharge path.
[0129] In the setting of the elastic conductive part 400, the elastic conductive part 400 can include a base 410 and an elastic arm 420, the base 410 is fixed on the first main body 100, the base 410 and the first main body 100 are electrically connected, and the elastic arm 420 serves as the elastic contact part 400a and is connected to the base 410.
[0130] The elastic conductive part 400 with the base 410 and the elastic arm 420 is easy to form. The base 410 is easy to assemble on the first main body 100, and the elastic arm 420 and the metal layer 300 on the first frame 100a can be reliably abutted, so that the metal layer 300 and the elastic conductive part 400 are combined to realize electrostatic discharge. The base 410 can be fixed on the first main body 100 by welding, fasteners (screws), etc., to realize the fixation and electrical connection between the elastic conductive part 400 and the first main body 100. The metal layer 300, the elastic arm 420, the base 410, and the first main body 100 form a reliable electrostatic discharge path.
[0131] There are various optional implementation ways in the setting of the elastic arm 420. Two implementation ways are exemplarily given below.
[0132] The first implementation way of the elastic arm 420: referring to (a), (b) in FIG. 13 and (a) to (c) in FIG. 14, the elastic arm 420 includes a bending segment 421, a swinging segment 422, and an abutting segment 423 connected in sequence, one end of the bending segment 421 away from the swinging segment 422 is connected to the base 410, the swinging segment 422 can swing around the axis 421a of the bending segment 421, and the abutting segment 423 abuts with the metal layer 300.
[0133] The elastic arm 420 with the bending segment 421, the swinging segment 422, and the abutting segment 423 is easy to form. The abutting segment 423 can swing around the axis 421a of the bending segment 421 following the swinging segment 422. Under the elastic force of the elastic arm 420, the abutting segment 423 and the metal layer 300 can be reliably abutted. The metal layer 300, the abutting segment 423, the swinging segment 422, the bending segment 421, the base 410, and the first main body 100 form a reliable electrostatic discharge path.
[0134] In order to reliably abut the abutting section 423 and the metal layer 300, in some embodiments, referring to (a) and (b) of FIG. 13, the abutting section 423 has a convex spherical surface 423a at one end away from the swinging section 422, and the convex spherical surface 423a abuts with the metal layer 300. Under the elastic force of the elastic arm 420, the convex spherical surface 423a of the abutting section 423 reliably abuts with the metal layer 300, and the contact area between the convex spherical surface 423a and the metal layer 300 is large, so that the impedance is small, which is beneficial to the external static electricity guidance.
[0135] In order to limit the maximum moving position of the swinging section 422, in some embodiments, referring to (a) and (b) of FIG. 13, the base 410 is provided with a limiting stop rib 430 for limiting the swinging range of the swinging section 422. The swinging section 422 can swing around the axis 421a of the bending section 421, and when the swinging section 422 moves to the limiting stop rib 430 and is blocked, the limiting stop rib 430 limits the maximum moving position of the swinging section 422, preventing the swinging section 422 from continuing to move. The limiting stop rib 430 can be L-shaped or other shapes.
[0136] In order to improve the structural strength of the elastic arm 420, in some embodiments, referring to (a) and (b) of FIG. 13, at least one of the bending section 421 and the swinging section 422 has a reinforcing rib 424. The reinforcing rib 424 can improve the structural strength of the elastic arm 420, so that the elastic arm 420 can reliably abut on the metal layer 300. The reinforcing rib 424 can be arranged along the extension direction of the bending section 421 and the swinging section 422.
[0137] When connecting the abutting section 423 and the swinging section 422, referring to (c) of FIG. 14, the included angle θ between the connecting area of the abutting section 423 connected with the swinging section 422 and the swinging section 422 is greater than or equal to 90°. The included angle θ between the connecting area of the abutting section 423 connected with the swinging section 422 and the swinging section 422 is the included angle θ between the segment of the abutting section 423 connected with the swinging section 422 and the swinging section 422 when the elastic conductive piece 400 is not installed on the first main body 100. This can make the elastic arm 420 have a certain yield strength, so that the elastic arm 420 and the metal layer 300 can reliably abut.
[0138] When arranging the base 410, referring to (a) and (b) of FIG. 13, the base 410 includes a first section 411 and a second section 412 connected with each other, the first section 411 and the second section 412 are arranged in an L shape, the first section 411 is connected with the first main body 100, the second section 412 is connected with the bending section 421, and the swinging section 422 is arranged spaced apart from the second section 412.
[0139] The base 410 with the first section 411 and the second section 412 is easy to be molded and assembled. The first section 411 is connected with the first body 100 to realize the fixation and electrical connection of the two. The first section 411 and the first body 100 can be connected by welding, fasteners (such as screws), etc. The swing section 422 is arranged in the space between the first section 411 and the second section 412 to form a swing space of the swing section 422, allowing the swing section 422 to swing around the axis 421a of the bending section 421. The limiting rib 430 can be connected to the second section 412. The first section 411 and the second section 412 can both be substantially rectangular.
[0140] When the abutting section 423 is arranged, the abutting section 423 is in the shape of a hook. The hook-shaped abutting section 423 can provide a certain elastic force, so that the end of the abutting section 423 can reliably abut on the metal layer 300.
[0141] When the bending section 421 is arranged, the axis 421a of the bending section 421 and the thickness direction of the first body 100 can be parallel, or the axis 421a of the bending section 421 and the thickness direction of the first body 100 can not be parallel. The above-mentioned scheme can make the swing section 422 swing around the axis 421a of the bending section 421, so that the abutting section 423 and the metal layer 300 can reliably abut.
[0142] When the elastic conductive piece 400 is made, the base 410, the bending section 421, the swing section 422, and the abutting section 423 can be integrally formed, such as a sheet metal piece. The integrally formed elastic conductive piece 400 is easy to make and has a reliable structure.
[0143] The second implementation manner of the elastic arm 420: The elastic arm 420 is substantially in the shape of a sheet. The base 410 is substantially in the shape of a sheet. The base 410 and the elastic arm 420 are arranged in an L shape and connected. This manner can install the base 410 on the first body 100, electrically connect the base 410 and the first body 100 in a large area, and arrange the elastic arm 420 against the metal layer 300 on the inner surface of the first frame 100a. The metal layer 300, the elastic arm 420, the base 410, and the first body 100 form a reliable electrostatic discharge path.
[0144] When the first frame 100a is made, the first frame 100a includes a substrate layer and an appearance coating layer arranged on the appearance surface of the substrate layer. The substrate layer can provide a certain strength as a base, and the appearance coating layer can provide a high-gloss or matte effect. The material of the substrate layer can include polycarbonate (PC), which has good impact resistance and toughness. The material of the appearance coating layer can include fiber glass (GF), which can improve the rigidity. The appearance coating layer can be arranged on the substrate layer by spraying and baking to reliably adhere the appearance coating layer to the appearance surface of the substrate layer.
[0145] The thickness of the material layer can range from 0.15 mm to 0.35 mm, and the thickness of the exterior coating can range from 0.03 mm to 0.1 mm. The thickness of the material layer and the exterior coating refer to the thickness of the material layer and the exterior coating, respectively, in the thickness direction of the second side 120 (i.e., the left-right direction in Figure 8). The overall thickness of the first frame 100a is small, which can shield and protect the edges of the first display module 200. By adjusting the thickness of the exterior coating, the exterior coating can be made to have a high-gloss or matte effect.
[0146] The mass ratio of the material layer and the exterior coating can range from 3 to 9. Set the material ratio of the material layer and the exterior coating as needed.
[0147] For example, the mass ratio of the material layer and the appearance coating is 9, the thickness of the material layer ranges from 0.15 mm to 0.35 mm, the thickness of the appearance coating is 0.05 mm, and the appearance effect of the first frame 100a is high gloss.
[0148] For example, the mass ratio of the material layer and the appearance coating is 4, the thickness of the material layer ranges from 0.15 mm to 0.35 mm, the thickness of the appearance coating is 0.05 mm, and the appearance effect of the first frame 100a is high gloss.
[0149] For example, the mass ratio of the material layer and the appearance coating is 3, the thickness of the material layer ranges from 0.15 mm to 0.35 mm, the thickness of the appearance coating is 0.05 mm, and the appearance effect of the first frame 100a is high gloss.
[0150] For example, the mass ratio of the material layer and the appearance coating is 9, the thickness of the material layer ranges from 0.15 mm to 0.35 mm, the thickness of the appearance coating is 0.03 mm, and the appearance of the first frame 100a is matte.
[0151] For example, the mass ratio of the material layer and the appearance coating is 4, the thickness of the material layer ranges from 0.15 mm to 0.35 mm, the thickness of the appearance coating is 0.03 mm, and the appearance effect of the first frame 100a is matte.
[0152] For example, the mass ratio of the material layer and the appearance coating is 3, the thickness of the material layer ranges from 0.15 mm to 0.35 mm, the thickness of the appearance coating is 0.03 mm, and the appearance of the first frame 100a is matte.
[0153] There are multiple optional process methods for manufacturing the first frame 100a having the metal layer 300. Two process methods are exemplified below.
[0154] The first process of the first bezel 100a with the metal layer 300: as shown in (a) of FIG. 15, a substrate layer is prepared; as shown in (b) of FIG. 15, the inner surface of the substrate layer corresponding to the bending part 220 of the first display module 200 is treated by laser; as shown in (c) of FIG. 15, after the inner surface of the substrate layer is activated, metal plating is performed, so that the inner surface of the substrate layer is attached with the metal layer 300, and the outer surface of the substrate layer needs to be shielded in this process; as shown in (d) of FIG. 15, an appearance coating is arranged on the outer surface of the substrate layer, and the metal layer 300 needs to be shielded in this process.
[0155] The second process of the first bezel 100a with the metal layer 300: as shown in (a) of FIG. 16, a substrate layer is prepared; an appearance coating is arranged on the outer surface of the substrate layer, and the inner surface of the substrate layer needs to be shielded in this process; as shown in (b) and (c) of FIG. 16, the inner surface of the substrate layer corresponding to the bending part 220 of the first display module 200 is treated by laser; as shown in (d) of FIG. 16, after the inner surface of the substrate layer is activated, metal plating is performed, so that the inner surface of the substrate layer is attached with the metal layer 300, and the appearance coating needs to be shielded in this process.
[0156] In the case that the electronic device 1000 is a folding machine, the folding machine has at least two main bodies, and adjacent two main bodies are hinged and can switch between a flat state and a closed state. The first display module 200 can be a flexible screen. In the flat state of the folding machine, the size of the flexible screen after being flattened is large, and the user has a good viewing experience. In the closed state of the folding machine, the structure is compact and convenient to carry. The electronic device 1000 can adopt an integrated antenna scheme and a distributed antenna scheme.
[0157] Referring to FIG. 17, the electronic device 1000 adopts an integrated antenna scheme, and a system on chip (SOC), a radio frequency integrated circuit (RFIC), a short-range antenna, and part of a mobile cellular antenna are integrated in the first circuit board 801 of the electronic device 1000. The mobile cellular antenna with a parasitic antenna is integrated in the second circuit board 802 of the electronic device 1000. The first circuit board 801 and the second circuit board 802 are respectively arranged on the second main body 600 and the first main body 100. In the integrated antenna scheme, the antenna 500 arranged at the edge of the first main body 100 includes a mobile cellular antenna with a parasitic antenna; the edge of the second main body 600 is provided with a short-range antenna and a mobile cellular antenna.
[0158] The short-range antenna can include an antenna of various short-range communication technologies such as a global positioning system (GPS), a wireless fidelity (WIFI), a bluetooth (BT) module, and the like.
[0159] The mobile cellular antenna is an antenna supporting a mobile cellular communication technology, which can include a parasitic antenna, which can be a medium and high frequency (MHF) parasitic antenna or a low frequency (LF) parasitic antenna.
[0160] For example, the first circuit board 801 is provided with at least one short-range antenna and at least one mobile cellular antenna. The first circuit board 801 is provided with a GPS1, a WIFI1, and a first mobile cellular antenna at a position 1, a second mobile cellular antenna at a position 2, a BT at a position 3, a GPS2, a WIFI2, and a third mobile cellular antenna at a position 4, a fourth mobile cellular antenna at a position 5, a fifth mobile cellular antenna at a position 6, and a sixth mobile cellular antenna at a position 7.
[0161] The second circuit board 802 is provided with at least one mobile cellular antenna with a parasitic antenna. The second circuit board 802 is provided with a seventh mobile cellular antenna with a MHF parasitic antenna at a position 8, an eighth mobile cellular antenna with a MHF parasitic antenna at a position 9, and a ninth mobile cellular antenna with a LF parasitic antenna at a position 10.
[0162] In the above integrated antenna scheme, the antenna coinciding with the bending part of the display module is mainly a mobile cellular antenna with a parasitic antenna, and the frequency is distributed in 0.7 GHz to 1 GHz. If the related technical conductive silver paste scheme shown in FIG. 3 is used, the conductive silver paste 16 is pad printed on the inner surface of the frame 15 corresponding to the bending part 1b of the display module 1 to form a pad printing area, and the grounding point of the middle frame 14 is provided with a laser etching area, so that the pad printing area and the laser etching area are directly connected or gap coupled. The conductivity of the conductive silver paste 16 is low, and the impedance is high, which will absorb part of the parasitic antenna energy and cause the antenna performance to deteriorate. The frequency of the parasitic antenna is relatively low, and the conductive silver paste 16 has less influence on the antenna performance of the parasitic antenna.
[0163] Referring to FIG. 18, the electronic device 1000 adopts a distributed antenna scheme, the system on chip and the short-range antenna are integrated in the first circuit board 801 of the electronic device 1000, the radio frequency integrated circuit and the mobile cellular antenna are integrated in the second circuit board 802 of the electronic device 1000, and the radio frequency integrated circuit and the display module bending part 220 are arranged coincidentally. The first circuit board 801 and the second circuit board 802 are arranged on the second main body 600 and the first main body 100 respectively. In the distributed antenna scheme, the antenna 500 arranged at the edge of the first main body 100 includes a mobile cellular antenna with a medium-high frequency parasitic antenna and a mobile cellular antenna with a low frequency parasitic antenna; and the short-range antenna is arranged at the edge of the second main body 600. The electronic components are reasonably distributed on the circuit board, the area of the circuit board occupied by the electronic devices is reduced, the distribution area of the battery is improved, and the capacity of the battery is higher.
[0164] For example, the first circuit board 801 is provided with at least one short-range antenna. The first circuit board 801 is provided with GPS1 and WIFI1 at position 1, WIFI2 at position 2, BT at position 3, GPS2 and WIFI3 at position 4, WIFI4 at position 5, WIFI5 at position 6, WIFI6 at position 7, WIFI7 at position 8, and WIFI8 at position 9.
[0165] The second circuit board 802 is provided with at least one mobile cellular antenna. The second circuit board 802 is provided with a first mobile cellular antenna with a medium-high frequency parasitic antenna at position 10, a second mobile cellular antenna with a medium-high frequency parasitic antenna at position 11, a third mobile cellular antenna with a medium-high frequency parasitic antenna at position 12, a mobile cellular antenna with a low frequency parasitic antenna at position 13, and a fourth mobile cellular antenna with a medium-high frequency parasitic antenna at position 14. The frequency range of the medium-high frequency can be 1000 megahertz (MHz) to 3000 MHz. The frequency range of the low frequency can be lower than 1000 MHz.
[0166] In the above-mentioned distributed antenna scheme, the antenna coinciding with the display module bending part is a mobile cellular antenna, which has all low-medium-high frequency mobile cellular antennas, and the frequency is distributed in 0.7 gigahertz (GHz) to 5 GHz. If the related technical conductive silver paste 16 scheme shown in FIG. 3 is adopted, the conductive silver paste 16 is pad printed on the inner surface of the frame 15 corresponding to the display module 1 bending part 1b to form a pad printing area, and the grounding point of the middle frame 14 is arranged in the laser etching area, so that the pad printing area and the laser etching area are directly connected or gap coupled. The conductivity of the conductive silver paste 16 is low and the impedance is high, which will absorb the antenna energy and cause the antenna performance to be poor. The energy loss of the medium-high frequency band antenna is large, which will have a large influence on the over the air (OTA) performance test.
[0167] When the folding machine adopts the distributed antenna scheme, it is difficult to realize electrostatic discharge by screen printing conductive silver paste 16 on the inner surface of the frame 15 combined with the middle frame 14 laser etching area, and can only realize electrostatic discharge by the protective glue 13 and conductive cloth 11 of the display module itself. As described above, the related art protective glue 13 and conductive cloth 11 lapping scheme, it is difficult to achieve the anti-static ability of the electronic device 1000 to reach 10kV.
[0168] In some embodiments, referring to FIGS. 4-6, one side of the first body 100 is provided with a first display module 200, the side of the first body 100 opposite to the first display module 200 is provided with a second display module 900, and the antenna 500 located at the edge of the first body 100 is located between the first display module 200 and the second display module 900 (i.e., the double-screen clamping side).
[0169] In this embodiment, in combination with FIG. 8, the metal layer 300 of the inner surface 100b of the first frame 100a, the elastic conductive part 400 of the first body 100 and the large area of the first body 100 are sequentially electrically connected. The metal layer 300 can be understood as a pure metal material, the conductivity of the metal layer 300 is relatively large, the impedance is relatively small, and the energy absorption of the antenna 500 is very small. The antenna 500 on the first body 100 is arranged adjacent to the metal layer 300, the metal layer 300 and the antenna 500 are coupled, the metal layer 300 acts as part of the antenna radiator to promote radiation, which can improve the antenna radiation efficiency of the double-screen clamping side, and make the over the air (OTA) performance index of the double-screen clamping side antenna higher.
[0170] The antenna 500 can include a mobile cellular antenna. For example, the antenna 500 can include a mobile cellular antenna with a mid-high frequency parasitic antenna, and a mobile cellular antenna with a low frequency parasitic antenna. The frequency range of the mid-high frequency can be 1000 megahertz (MHz) to 3000 MHz. The frequency range of the low frequency can be lower than 1000 MHz.
[0171] In some embodiments, the electronic device 1000 is a folding machine, and the first body 100 and the second body 600 are hinged. The first display module 200 is provided on the same side of the first body 100 and the second body 600 in the unfolded state, the second display module 900 is provided on the side of the first body 100 opposite to the first display module 200, and the back cover is provided on the side of the second body 600 opposite to the first display module 200. The antenna 500 is located between the first display module 200 and the second display module 900 (i.e., the double-screen clamping side). The antenna can also be arranged between the back cover and the first display module 200 (i.e., the non-double-screen clamping side). The first display module 200 can serve as the inner screen of the electronic device 1000, and the second display module 900 can serve as the outer screen of the electronic device 1000.
[0172] If the metal layer 300, the elastic conductive member 400 and the first main body 100 are not sequentially electrically connected, when the folding machine is in a closed state, the first main body 100 and the second main body 600 are closed together, and a natural cavity is formed between the first display module 200 and the second display module 900, which causes the low-frequency band to enter the band.
[0173] In this embodiment, the metal layer 300, the elastic conductive member 400 and the first main body 100 are sequentially electrically connected, which can effectively block the generation of cavity clutter, inhibit the energy coupling of the antenna 500 main feeder branch on the double-screen clamping side from entering the cavity, play a role in shielding signal crosstalk, improve the radiation efficiency of the double-screen clamping side antenna, and make the air performance indicators of the double-screen clamping side antenna and the non-double-screen clamping side antenna equivalent. By sequentially electrically connecting the metal layer 300, the elastic conductive member 400 and the first main body 100 to block the cavity clutter, this scheme can be applied to an integrated antenna scheme and a distributed antenna scheme.
[0174] When the metal layer 300 is arranged, referring to FIG. 19, in the case where the antistatic ability of the electronic device 1000 is greater than or equal to 10 kilovolts (kV), the length L1 of the metal layer 300 in the length direction of the bending part 220 (the left-right direction of FIG. 19) is less than or equal to the length L2 of the bending part 220.
[0175] When the antistatic ability of the entire electronic device 1000 is greater than or equal to 10 kilovolts, the metal layer 300 does not need to be completely arranged on the inner surface 100b of the first frame 100a corresponding to the entire bending area 212, and the metal layer 300 can be arranged locally at a position where the antenna clutter and the antenna efficiency need to be improved, so that the metal layer 300 and the elastic connecting part 400a of the elastic conductive member 400 abut, and the elastic conductive member 400 and the first main body 100 are electrically connected in a large area, which can effectively block the cavity clutter and improve the radiation efficiency of the double-screen clamping side antenna.
[0176] Under the premise that the antistatic ability of the entire electronic device 1000 is greater than or equal to 10 kilovolts, simulation tests are respectively performed on the antenna of this embodiment provided with the metal layer 300 and the comparative antenna without the metal layer. In this embodiment, the metal layer 300 on the inner surface 100b of the first frame 100a, the elastic conductive member 400 of the first main body 100 and the first main body 100 are sequentially electrically connected. The radiation efficiency curves of this embodiment and the comparative example are shown in FIG. 20, where the solid line represents the radiation efficiency of the antenna provided with the metal layer 300, and the dotted line represents the radiation efficiency of the antenna without the metal layer. In the B8 (880 MHz to 960 MHz) frequency band, compared with the radiation efficiency of the comparative antenna, the radiation efficiency of the antenna of this embodiment is improved by more than 1 dB, and it can be seen that this embodiment has a higher radiation efficiency.
[0177] For example, referring to FIG. 19, a metal layer 300 is arranged on the inner surface 100b of the first frame 100a corresponding to one end of the bending part 220, which can block the generation of antenna clutter and improve the antenna radiation efficiency of the predetermined frequency band.
[0178] In some embodiments, the electronic device 1000 is a slide phone, and the first display module 200 can be a flexible screen or a rigid screen. The electronic device 1000 further includes a second main body 600, and the second main body 600 and the first main body 100 are slidingly connected. The first main body 100 is provided with the first display module 200, and the second main body 600 can be provided with a second display module 900. The metal layer 300 of the inner surface 100b of the first frame 100a, the elastic conductive part 400 of the first main body 100, and the large area of the first main body 100 are sequentially electrically connected, which can guide and release external static electricity along the static electricity release path, thereby achieving static electricity protection for the first display module 200.
[0179] In some embodiments, the electronic device 1000 is a straight phone. The first display module 200 can be a flexible screen or a rigid screen. The first main body 100 is provided with the first display module 200, and the metal layer 300 of the inner surface 100b of the first frame 100a, the elastic conductive part 400 of the first main body 100, and the large area of the first main body 100 are sequentially electrically connected, which can guide and release external static electricity along the static electricity release path, thereby achieving static electricity protection for the first display module 200.
[0180] In some embodiments, the first display module 200 can be an electrochromic back cover, a photochromic back cover, or other non-screen modules. The metal layer 300 of the inner surface 100b of the first frame 100a, the elastic conductive part 400 of the first main body 100, and the large area of the first main body 100 are sequentially electrically connected, which can guide and release external static electricity along the static electricity release path, thereby achieving static electricity protection for the non-screen module.
[0181] In order to confirm whether the electronic device 1000 of the embodiments of the present application is adopted, the electronic device 1000 can be disassembled and analyzed to confirm that the inner surface 100b of the first frame 100a has a metal layer 300, the elastic conductive part 400 is installed on the first main body 100, and the elastic connecting part 400a of the elastic conductive part 400 is arranged on the metal layer 300 to form an electrical connection. The metal layer 300 can be understood as a pure metal material, and the impedance between the two ends of the metal layer 300 in the extension direction of the first frame 100a is less than or equal to 1 ohm, which can be measured by an ohmmeter.
[0182] Finally, it should be noted that the above only describes specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any changes or replacements within the technical scope disclosed by the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
