The present invention discloses a FPD-LINK vehicle-mounted information transmission circuit comprises an ARM processor module, a serializer module used for data sending, an FPD-LINK wire harness usedfor high-speed serial data flow, a deserializer module used for receiving data and a vehicle-mounted information displayer used for displaying audios and videos. A control chip U1 is arranged in the ARM processor module, and the serializer module is connected with the data end of the control chip U1; the serializer module is connected with the deserializer module through the FPD-LINK, the deserializer is connected with the vehicle-mounted information display, and a display screen device is arranged in the vehicle-mounted information display. The FPD-LINK wire harness is adopted to connect thevehicle-mounted entertainment central control system with the display instrument panel, the cost of the FPD-LINK wire harness is low, so that the control signals are transmitted when audio and video signals are transmitted. The transmitted audios and videos are higher in definition, and the real-time performance of user operation response is achieved.
