The invention discloses a video digital signal transmission line used for a notebook computer. The video digital signal transmission line is characterized by comprising a display screen butt junction for butting an LED (light-emitting diode) display screen, a mainboard butt junction for butting a PCB (printed circuit board) mainboard and a camera butt junction for butting a camera, wherein the mainboard butt junction adopts an FPC (flexible printed circuit) joint which is connected in series with the display screen butt junction and the camera butt junction through a cable connecting line; and the display screen butt junction and the input joint of the display screen are welded and fixed through soldering wires, the mainboard butt junction and the PCB mainboard are welded and fixed through soldering wires, and the camera butt junction and the camera are welded and fixedly through soldering wires. The video digital signal transmission line has the advantages of high transmission speed/definition, stable EMI (electromagnetic interference) property and characteristic impedance, strong universality and strong signal transmission stability; and in addition, the manpower can be effectively saved, the product quality is controlled, the problem of abnormal LED display during the product assembling and using process is solved, and the tin melting yield of welding points is effectively increased, therefore, the product quality is improved.
