ABSTRACT:
A source driver which can control the spatial cycle of inverting the polarity of offset voltage in response to the spatial cycle of inverting the polarity of data signal. The liquid crystal display device according to the present invention has an LCD panel, having data lines, and source drivers for supplying data signal to the data lines. The source driver includes an offset cancel control circuit for generating an offset cancel control signal and an amplifier used for generating the data signal, which is configured so as to invert the polarity of the offset voltage in response to the offset cancel control signal OCC. The offset cancel controller circuit receives the pattern select signal PSEL specifying the cycle of inverting the polarity of the offset voltage of the amplifier to generate the offset cancel control signal in response to the pattern select signal PSEL.
