Abstract: A source driver adapted to drive a display panel is provided. The source driver includes an output buffer and a slew rate adjustment circuit. An input terminal of the output buffer receives a driving voltage. An output terminal of the output buffer outputs an output signal adapted to drive the display panel. The slew rate adjustment circuit dynamically adjusts a slew rate of a rising edge of the output signal according to a first setting and dynamically adjusts a slew rate of a falling edge of the output signal according to a second setting independent of the first setting, such that the adjustment to the slew rate of the rising edge of the output signal is independent of the adjustment to the slew rate of the falling edge of the output signal.
