Description

Technical Field

[0001] This utility model relates to the field of wearable device technology, and in particular to a wearable device FPC structure with anti-interference function. Background Technology

[0002] In today's technological age, the wearable product market continues to grow, and consumers are placing higher demands on product performance, appearance, and reliability. However, the design of FPCs in existing wearable products often has some shortcomings. On the one hand, the shape of the FPC does not match the shape of the display screen, resulting in inefficient space utilization. The small area makes it difficult to route electronic components, affecting the overall design and performance of the product. On the other hand, wearable products are susceptible to external electromagnetic interference, affecting the stability and accuracy of signal transmission; specifically, for example... Figure 1 The image shows the traditional FPC structure for wearable devices. It mainly consists of three core components: a display screen, a shielding layer, and the FPC itself. Typically, the FPC's shape differs from the display screen's, resulting in a smaller FPC area and constraining wiring design, making routing difficult. Furthermore, the shielding layer needs to match the display screen's shape to ensure effective shielding. During assembly, the shielding layer must first be fixed to the display screen before being connected to the FPC and having its pins soldered. Testing can only be performed after assembly to determine if it is a good product. The entire process is relatively complex. Therefore, further improvements to the FPC structure are needed to meet the requirements of wearable devices. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing a wearable device FPC structure with anti-interference function.

[0004] The technical solution of this utility model is a wearable device FPC structure with anti-interference function, including an FPC layer integrated on the display screen. The FPC layer is connected to the display screen through a ribbon cable and communicates with the display screen.

[0005] The FPC layer has the same shape as the display screen; and the FPC layer facing the display screen has a shielding layer.

[0006] Preferably, the shielding layer completely covers the FPC layer.

[0007] Preferably, the shielding layer is a copper shielding layer.

[0008] Preferably, the FPC layer utilizes a shielding layer to shield against external electromagnetic interference and reduce the outward radiation of internal signals.

[0009] Preferably, the FPC layer uses a shielding layer to transfer heat outwards, dissipating the heat generated by the electronic components during operation.

[0010] Preferably, one end of the FPC layer is provided with a connector for connection to the motherboard.

[0011] Preferably, the connector extends outward from the FPC layer.

[0012] Preferably, after the connector is connected to the motherboard, a section of the connector can be bent to the back of the FPC layer.

[0013] Preferably, the shielding layer is pre-integrated with the FPC layer to form a component, and then installed with the display screen and motherboard.

[0014] Preferably, the shielding layer is pre-fixed to the FPC layer by adhesive, and grounding pins are provided on the edge of the shielding layer; the grounding pins are connected to the wiring circuit of the FPC by soldering or crimping.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects:

[0016] This invention improves upon existing FPC layers by designing them to match the shape of the display screen. During assembly, the shielding layer can be directly aligned and installed with the FPC layer. The resulting assembly is then tested to ensure both the FPC layer and the shielding layer are of good quality before assembly with the display screen. This pre-determining of component quality avoids wasting manpower and resources in the assembly process. Furthermore, compared to traditional designs, it reduces the installation process between the shielding layer and the display screen, improving production efficiency. The identical shape to the display screen ensures a tight fit and maximizes space utilization. This design not only enhances the product's aesthetics but also simplifies the routing of electronic components, reducing circuit length and complexity, and improving signal transmission efficiency and stability.

[0017] In FPC design, the ample space facilitates easy wiring and layout design, resulting in more rational and concise routing of electronic components. By optimizing the routing and connection methods, interference and crosstalk between signals are reduced, improving signal transmission quality.

[0018] Finally, the copper shielding layer effectively blocks external electromagnetic interference from affecting electronic components. In the environment where wearable products are used, various electromagnetic signals are often present, such as wireless communication signals and radiation from electronic devices. These signals may interfere with the normal operation of the electronic components inside the wearable product. Copper has excellent conductivity and electromagnetic shielding properties, which can guide external electromagnetic interference signals to ground, protecting the normal operation of the internal electronic components. Secondly, the copper shielding layer can also reduce the external radiation of internal signals, preventing the wearable product from interfering with other electronic devices. Furthermore, the copper shielding layer helps improve the heat dissipation performance of the FPC. Electronic components generate heat during operation, and copper's high thermal conductivity can quickly dissipate this heat, extending the product's lifespan. Attached Figure Description

[0022] Example 1

[0023] like Figure 2 As shown, the wearable device FPC structure with anti-interference function proposed in this utility model includes an FPC layer 2 integrated on the display screen 1. The FPC layer 2 is connected to the display screen 1 through a ribbon cable and communicates with the display screen 1.

[0024] The FPC layer 2 has the same shape as the display screen 1; and a shielding layer 3 is provided on the FPC layer 2 facing the display screen 1. In this embodiment, the shielding layer 3 needs to completely cover the FPC layer 2.

[0025] As a preferred embodiment, the shielding layer 3 is a copper shielding layer. The FPC layer 2 utilizes the shielding layer 3 to shield against external electromagnetic interference and reduce the outward radiation of internal signals. The FPC layer 2 also utilizes the shielding layer 3 to transfer heat outward, dissipating the heat generated by the electronic components during operation. Specifically, the copper shielding layer effectively blocks the influence of external electromagnetic interference on the electronic components. In the usage environment of wearable products, various electromagnetic signals often exist, such as wireless communication signals and radiation from electronic devices. These signals may interfere with the normal operation of the electronic components inside the wearable product. Copper has good conductivity and electromagnetic shielding performance, which can guide external electromagnetic interference signals to ground, protecting the normal operation of the internal electronic components. Secondly, the copper shielding layer can also reduce the outward radiation of internal signals, preventing the wearable product from interfering with other electronic devices. Furthermore, the copper shielding layer helps improve the heat dissipation performance of the FPC. Electronic components generate heat during operation, and the high thermal conductivity of copper can quickly dissipate the heat, extending the product's lifespan.

[0026] In this embodiment, one end of the FPC layer 2 is provided with a connector 21 for connection to the motherboard, and the connector 21 extends outward from the FPC layer 2. After the connector 21 is connected to the motherboard, the extended part of the connector can be bent to the back of the FPC layer 2. The shielding layer 3 is pre-integrated with the FPC layer 2 to form an assembly, and then installed with the display screen 1 and the motherboard. The shielding layer 3 is pre-fixed to the FPC layer 2 by adhesive, and grounding pins are provided on the edge of the shielding layer 3. The grounding pins are connected to the wiring circuit of the FPC by soldering or crimping. After the shielding layer 3 and the FPC layer 2 form an assembly, they can be tested to determine whether the assembly is good or not before it is installed with the display screen 1. This avoids the product being a defective product due to the failure of the FPC layer 2 or the shielding layer 3. This method can determine the quality of the assembly in advance, avoiding the waste of manpower and resources in the assembly process. In addition, since the shielding layer 3 and the FPC layer 2 are designed with the same shape, they can be directly aligned and installed with the FPC layer 2, which is more convenient. In the traditional design, because the shielding layer 3 and the FPC layer 2 have different shapes, the shielding layer 3 can only be installed with the display screen 1 first to ensure accurate alignment when it is installed with the FPC layer 2 later.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
