FPC10 includes a binding end 20 and an interface end 30, and the binding end 20 and the interface end 30 of FPC10 are respectively located at two ends of FPC10. The binding end 20 of FPC10 is used to bind with the display screen, and the binding of the binding end 20 and the display screen is fixed after one binding. The interface end 30 of FPC10 is used to connect with the customer's mainboard, and multiple plug-ins may be required during the connection process.

[0025] Reference Figure 1 and Figure 2 In order to prevent the electroplated lead from remaining at the end of the interface end 30 after electroplating to cause a short circuit during multiple plugging, a plating layer 40 is provided on the binding end 20 of the FPC 10, and the plating layer 40 is connected to the interface end 30. By providing the plating layer 40 on the binding end 20 of the FPC 10, the interface end 30 of the FPC 10 can be prevented from causing a short circuit after multiple plugging.

[0026] Reference Figure 1 and Figure 2 The electroplating layer 40 is plated on the surface of the binding end 20, and the electroplating layer 40 is provided with an electroplating lead, one end of the electroplating lead is an electroplating lead crimping area 41, and the electroplating lead crimping area 41 is located at the binding end 20 facing the display screen. The binding end 20 is fixed after the binding mode with the display screen is a one-time binding, and the electroplating lead crimping area 41 will not short-circuit after the binding end 20 is bound once, thereby avoiding the risk of short circuit.

[0027] Reference Figure 1 and Figure 2 The binding end 20 and the interface end 30 of the FPC 10 are connected so that the electroplating layer 40 provided on the binding end 20 can also act on the interface end 30, thereby improving the conductive performance and service life of the interface end 30.

[0028] Reference Figure 1 and Figure 2A plurality of binding leads 21 are provided at the binding end 20, and the plurality of binding leads 21 are used to bind to the display screen. A plurality of interface leads 31 are provided at the interface end 30, and the plurality of interface leads 31 are used to connect to the customer's mainboard. The plurality of interface leads 31 are connected one-to-one with the plurality of binding leads 21 corresponding to the binding end 20, so that the interface end 30 and the binding end 20 are connected, and the electroplating effect of the electroplating layer 40 can also act on the interface end 30.

[0029] Further, refer to Figure 1 The number of interface leads 31 of the interface end 30 is set as an odd number, and the interface leads 31 of the interface end 30 retain the odd number leads as a reserve, and additional electroplating can be performed from the interface end 30 when necessary, thereby ensuring the electroplating effect of the interface end 30.
