A signal line precharge method is provided. The signal line precharge method for precharging a signal line connected to an auxiliary source driver to a predetermined voltage level in a precharge mode involves, in response to the combination of a polarity inversion signal of input data and the most significant bit of the input data, outputting one voltage level selected among precharge voltages having different voltage levels, and in response to a precharge timing control signal, precharging the signal line to the selected voltage level. In the precharge method, in response to change of the polarity inversion signal and change of the MSB of data being input, a signal line connected to the auxiliary source driver is precharged to an optimal precharge level such that a short and constant slew rate of all output signal is maintained.
