Abstract
Disclosed is a method of driving a source driver of an LCD which can reduce power consumption of the LCD by reducing the operating range of an amplifier provided on the last terminal of a source driver. According to the method, the output terminal of the source driver is kept at a specified level by connecting the output terminal of the source driver to a gamma reference voltage having a certain level among the plurality of gamma reference voltages in the standby state of the source driver. If the display data of the next frame has a voltage level of a positive region in the standby state, the output terminal of the source driver is connected to the gamma reference voltage having an intermediate level of the positive region, while if the display data of the next frame has a voltage level of a negative region in the standby state, the output terminal of the source driver is connected to the gamma reference voltage having an intermediate level of the negative region.
