摘要： A source driver includes a gamma voltage generator, in which the gamma voltage generator includes a first gamma resistor string and a second gamma resistor string. The first gamma resistor string receives a first gamma reference voltage and generates a plurality of first gamma voltages. The second gamma resistor string receives a second gamma reference voltage and generates a plurality of second gamma voltages, in which the second gamma voltages have different voltage values from the first gamma voltages. The switch circuit selects the first gamma voltages or the second gamma voltages as output gamma voltages according to a timing control signal. The digital to analog converter selects one of the output gamma voltages as a driving voltage corresponding to a received digital pixel data for driving a first pixel region or a second pixel region of the sub-pixel.
