An apparatus for driving a thin-film transistor liquid crystal display is provided. The apparatus is able to reduce power consumption of its source driver IC in the vertical blanking time without affecting image quality in the normal display time. The apparatus comprises an application-specific integrated circuit (ASIC) and a source driver IC. The ASIC outputs a latch pulse signal. The source driver IC has a plurality of output terminals and outputs a data voltage at each of the output terminals in response to the latch pulse signal. The source driver IC further comprises a switch. The switch is electrically connected to two adjacent output terminals of the source driver IC and connects the adjacent output terminals in the vertical blanking time in response to the latch pulse signal.
