[0030] As described in the background art, a complete FPC is used to connect the display screen to the host to achieve signal transmission and power supply. However, with the increasing complexity and diversification of modern electronic products, this traditional single FPC design has gradually exposed a series of problems. First, the traditional single FPC design is easily damaged by electrostatic interference in the external environment or abnormal fluctuations in input voltage / current. These external factors may cause components on the FPC to fail, thereby causing display screen failure. Once a display screen fails, the repair process is often very complicated and the repair success rate is low. Due to the complexity of the internal structure of the display screen, maintenance personnel often need to spend a lot of time and energy to locate the fault point and repair it, which not only increases repair costs but also reduces product reliability and user satisfaction. Second, the traditional single FPC design has limitations in compatibility. With the continuous upgrading of electronic products, the wiring sequence and interface standards of the display screen are also constantly changing. If the wiring sequence of the display screen needs to be changed, the traditional single FPC design often requires redesigning and manufacturing the entire FPC, which not only increases production costs but also may lead to waste of inventory materials. In addition, the traditional single FPC design also has many inconveniences in repair and replacement. Since the entire display screen is usually regarded as a whole, when a component fails, the entire display screen often needs to be scrapped, which not only increases the maintenance cost, but also causes unnecessary waste to the environment.
