[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clear, this application is further described in detail below with reference to the accompanying drawings and embodiments.

[0035] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0040] In the description of the present application, “plurality” means two or more, unless otherwise clearly defined.

[0041] In order to solve the technical problems in the prior art that the outer layer of the flat cable is easily scratched by other components in the display screen, the entire flat cable is crushed and the line is broken, and the flat cable is not resistant to electromagnetic interference; therefore, the embodiments of the present invention provide a flat cable structure and a display screen.

[0042] The following describes in detail the specific structure of the wiring structure provided by the embodiment of the present invention. Figure 1-2 As shown in FIG, the specific structure of the cable structure includes a cable body 11, an electromagnetic shielding film 12, an acetate tape 13 and a foam block 14.

[0043] The cable body 11 is an FPC or FPCB, that is, a Flexible Printed Circuit Board 23. The cable can accommodate a large number of data transmission lines in a limited device space, simplifying the internal structure of the device and saving the volume and weight of the entire electronic device. When an electrical signal or data signal needs to be transmitted, the signal source sends the signal through the cable, and at the same time, the cable transmits the received electrical signal or data signal to the target device.

[0044] The electromagnetic shielding film 12 covers the outer surface of the cable body 11 .

[0045] Specifically, electromagnetic interference is a common problem that can affect the performance and stability of a device during use. Therefore, by covering the outer surface of the cable body 11 with an electromagnetic shielding film 12, the impact of electromagnetic interference on the device can be effectively reduced. More specifically, the electromagnetic shielding film 12 typically comprises one or more layers of conductive material, such as copper, aluminum, or other metal foil. Made from such conductive materials, it forms a continuous conductive layer that effectively isolates the external electromagnetic field from the cable's internal circuitry. When electromagnetic waves encounter the conductive layer, they are reflected and absorbed. The conductive layer absorbs some of the electromagnetic wave's energy, reducing its impact on the internal circuitry by penetrating the cable body 11. Through the conductive layer, the electromagnetic shielding film 12 balances the electric field distribution on both sides of the cable body 11, reducing the electric field strength and thereby lowering electromagnetic interference. This ensures the signal quality of the cable transmission, avoids external interference, and prevents internal signals from affecting the external environment.

[0046] It is understandable that the electromagnetic shielding film 12 in the embodiment of the present invention is a metal mesh film, a metal-plated film or a conductive plastic film, and the specific type is not limited here.

[0047] The acetate tape 13 covers a portion of the two side surfaces of the electromagnetic shielding film 12 .

[0048] Specifically, acetate tape 13 has excellent wear and corrosion resistance. By wrapping it around the two side surfaces of electromagnetic shielding film 12, it helps prevent scratches on the cable. More specifically, acetate tape 13 is a soft and wear-resistant material with excellent adhesion and insulation properties. While non-conductive, it effectively covers and adheres to the surface of electromagnetic shielding film 12 to form a protective layer, thereby preventing damage from scratches and impacts. Due to its excellent ductility and wear resistance, it can effectively resist external pressure and friction, such as scratches on the outer layer of cable body 11 caused by burrs on the metal bracket inside the display. Therefore, by wrapping it around the surface of electromagnetic shielding film 12, it can resist friction and impact pressure, thereby preventing scratches on the electromagnetic shielding film 12 and the cable.

[0049] It should be noted that the acetate tape 13 has good adhesion. By attaching the acetate tape 13 to the surface of the shielding film, it plays a fixing and protective role to avoid damage and poor contact caused by loosening due to long-term friction and vibration.

[0050] A first opening is formed through the electromagnetic shielding film 12 to expose a portion of the surface of the cable body 11 . The foam block 14 is attached to the surface of one side of the cable body 11 through the first opening.

[0051] Specifically, the foam block 14 has good elasticity and cushioning properties, so the foam block 14 is attached to the first opening on the exposed surface of the cable body 11. When other objects press against the foam block 14 of the cable body 11, the foam block 14 can absorb part of the pressure, thereby reducing the direct impact on the cable. In addition, the softness of the foam block 14 can form a protective layer around the cable body 11, further dispersing the pressure and reducing the risk of the cable body 11 being crushed.

[0052] It can be understood that the foam block 14 of the embodiment of the present invention is an ethylene vinyl acetate copolymer foam block 14. The ethylene vinyl acetate copolymer foam block 14, fully known as EVA foam, is a new type of polymer environmentally friendly material with good elasticity and softness. It can absorb and disperse external impact force, provide protection for cables or other fragile components, and prevent them from being damaged or broken.

[0053] In some specific embodiments, at least two acetate tapes 13 are provided, and each acetate tape 13 is provided on the surfaces of two side surfaces of the electromagnetic shielding film 12 at intervals along the length of the electromagnetic shielding film 12 .

[0054] Specifically, each acetate tape 13 should be long enough to cover the majority of the cable, including the cable and other areas susceptible to electromagnetic interference. Therefore, properly spacing the acetate tapes 13 ensures a more uniform shielding effect. It should be noted that, depending on the actual cable situation, multiple acetate tapes 13 can be attached to the front and back, or left and right sides, of the electromagnetic shielding film 12. This arrangement ensures effective shielding of electromagnetic radiation from the cable in different directions.

[0055] In some specific embodiments, the electromagnetic shielding film 12 has a second opening for exposing a portion of the surface of the cable body 11 . The cable structure further includes a conductive double-sided tape 15 , the first adhesive surface of which is attached to the surface of the cable body 11 through the second opening.

[0056] Specifically, in order to achieve the stably attached cable to the installation position or bonding position, the first bonding surface of the conductive double-sided tape 15 is attached to the surface of the cable body 11 through the second through hole, and the second bonding surface of the conductive double-sided tape 15 is adhered to the installation position or bonding position (such as the support frame 22 in the display screen). The strong adhesion of the conductive double-sided tape 15 allows the cable structure to be attached to the installation position or bonding position, preventing the entire cable structure from easily falling off, thereby improving the stability of the cable structure.

[0057] The application of the conductive double-sided tape 15 in the wiring structure is to add a conductive agent to the glue to make the glue conductive. The main components of the conductive double-sided tape 15 are adhesive and conductive agent. For example, the adhesive is the basis of the conductive double-sided tape 15 and plays the role of sticking objects. The conductive agent is the key to the conductive double-sided tape 15 and has conductive properties. For example, commonly used conductive agents include metal powder, carbon fiber, carbon black, etc., which ensure the adhesion of the entire wiring structure and the conduction of current.

[0058] The following describes in detail the specific structure of a display screen provided by the embodiment of the present invention. Figure 3-4 As shown in , the specific structure of the display screen includes a display screen body 21, a support frame 22, a circuit board 23 and a wiring structure of any of the above embodiments.

[0059] An assembly cavity 211 is formed in the display screen body 21 ; an inner display screen 212 is also provided in the display screen body 21 ; a support frame 22 is detachably built into the assembly cavity 211 ; a circuit board 23 is built into the assembly cavity 211 and detachably provided on the support frame 22 .

[0060] Specifically, the assembly cavity 211 is the internal cavity of the display screen body 21. The size and shape of the assembly cavity 211 are designed according to needs and can accommodate other components. The support frame 22 is detachably built into the assembly cavity 211 to support and protect the circuit board 23 and other electronic components inside the display screen. The circuit board 23 is detachably set on the support frame 22 or directly integrated into the assembly cavity 211 to simplify the maintenance and disassembly process. That is, when the circuit board 23 needs to be replaced or repaired, it is only necessary to remove the circuit board 23 from the support frame 22.

[0061] The cable structure is sandwiched between the support frame 22 and the wall of the assembly cavity 211 ; one end of the cable body 11 is electrically connected to the display inner screen 212 , and the other end of the cable body 11 is electrically connected to the circuit board 23 .

[0062] Specifically, the support frame 22 and the wall of the assembly cavity 211 work closely together to clamp the cable structure between the two, and the friction between the two prevents the cable from loosening, falling off or deviating due to external forces or vibrations.

[0063] In some specific embodiments, a cavity wall of the assembly cavity 211 is provided with a protrusion 24 ; the support frame 22 is provided with a pressing portion 25 for pressing the foam block 14 of the cable body 11 until it abuts against one side of the protrusion 24 .

[0064] Specifically, the projection 24 plays a role in positioning and structural support of the cable arrangement structure. At the same time, the pressing portion 25 on the support frame 22 presses the foam block 14 of the entire cable arrangement structure until the foam block 14 abuts against one side of the projection 24, so that the cable arrangement is firmly fixed in a predetermined position, that is, the cable arrangement structure is clamped between the projection 24 and the pressing portion 25. Due to the buffering effect of the foam block 14, even if the cable arrangement structure is clamped between the projection 24 and the pressing portion 25, it is difficult to cause damage to the cable arrangement structure. This arrangement prevents the cable arrangement structure from loosening, falling off or shifting during the assembly process, thereby ensuring the stability of the cable arrangement structure after assembly.

[0065] In some specific embodiments, a positioning frame 26 is further provided in the assembly cavity 211, the positioning frame 26 is provided with a first fixing hole, and the support frame 22 is penetrated by a first locking hole; the display screen also includes a first locking member 27, and the first locking member 27 is simultaneously passed through the first locking hole and the first fixing hole.

[0066] Specifically, in order to improve the convenience of the support frame 22 during the disassembly and assembly process, when assembling the support frame 22, it is only necessary to connect the first fixing hole on the positioning frame 26 with the first locking hole on the support frame 22, and then insert the first locking piece 27 into the first locking hole and the first fixing hole at the same time so that the support frame 22 can be fixed on the positioning frame 26. This arrangement improves the convenience of assembling the support frame 22 and the positioning frame 26; conversely, when disassembling the support frame 22, it is only necessary to detach the first locking piece 27 from the first fixing hole and the first locking hole, and then the support frame 22 can be directly taken out.

[0067] In some specific embodiments, the support frame 22 is provided with a second fixing hole, and the circuit board 23 is penetrated by a second locking hole; the display screen further includes a second locking member 28, and the second locking member 28 is simultaneously provided in the second locking hole and the second fixing hole.

[0068] Specifically, when assembling the circuit board 23, it is only necessary to connect the second fixing hole on the support frame 22 with the second locking hole on the circuit board 23, and then insert the second locking piece 28 into the second locking hole and the second fixing hole at the same time so that the circuit board 23 can be fixed on the support frame 22. This arrangement improves the convenience of assembling the circuit board 23; conversely, when disassembling the circuit board 23, it is only necessary to detach the second locking piece 28 from the second fixing hole and the second locking hole, and then the entire circuit board 23 can be directly taken out.

[0069] It can be understood that the first locking member 27 and the second locking member 28 of the embodiment of the present invention are both bolts, and the first fixing hole, the second fixing hole and the first locking hole, the second locking hole are all threaded holes. By connecting the thread of the bolt with the thread of the two threaded holes, it is difficult for the bolt to loosen or fall off, so that the support frame 22 is fixedly assembled on the positioning frame 26, thereby improving the firmness of both.

[0070] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
