Abstract
A source driver and a polarity inversion control circuit are provided. The source driver includes a plurality of channel pairs and the polarity inversion control circuit. The polarity inversion control circuit includes a signal generating circuit and a routing circuit. The signal generating circuit generates a polarity control signal. The routing circuit outputs a plurality of switching control signals corresponding to the polarity control signal to a plurality of output switching circuits of the channel pairs. The routing circuit changes the correspondence between the polarity control signal and the switching control signals according to a polarity inversion configuration signal.
