Abstract
A source driver, which has a first resistor string, a first digital-to-analog converter, and a channel buffer, is provided. The first resistor string has a plurality of resistors connected in series, wherein each of the resistors of the first resistor string provides a corresponding gamma voltage. The first digital-to-analog converter is coupled to the resistors of the first resistor string. The digital-to-analog converter selectively outputs one of gamma voltages provided by the resistors as a first output voltage according to a data code. The channel buffer is coupled to an output terminal of the first digital-to-analog converter to output a second output voltage by shifting a voltage level of the first output voltage.
