ABSTRACT:
A liquid crystal display apparatus includes a liquid crystal display panel having a data line and a source driver for supplying a data signal to the data line based on a polarity signal. A polarity of the data signal is determined based on the polarity signal. The source driver includes an offset cancel control circuit for generating an offset cancel control signal and an output amplifier used to generate the data signal. The output amplifier is constructed so as to invert a polarity of an offset voltage based on the offset cancel control signal. The offset cancel control signal is generated based on the polarity signal.
