PURPOSE: A liquid crystal display(LCD) driving system is provided to achieve a slim and lightweight LCD while simplifying the layer configuration of printed circuit board (PCB) mounted with a source driver IC and a gate driver IC. CONSTITUTION: An LCD driving system comprises a signal supply source, one or more low voltage differential signal receiving units(40,42), and an LCD module(44). The signal supply source includes a graphic card(32) for outputting a color signal and a plurality of control signals for forming a predetermined screen, a timing controller(34) for determining a timing format for a plurality of color signals and control signals outputted from the graphic card, and one or more low voltage differential signal transmitting units(36,38) for converting the signals outputted from the timing controller(34) into low voltage differential signals and outputting the converted signals. The low voltage differential signal receiving units(40, 42) inversely convert the low voltage differential signals outputted from the signal supply source into TTL signals. The LCD module(44) forms a screen using the thus-obtained TTL signals.
