Abstract
A liquid crystal driver includes a voltage generator for generating gray scale voltages on the basis of reference voltages, and an output device for selecting one gray scale voltage from the generated gray scale voltages in accordance with display data, for applying inversion/non-inversion control to the selected gray scale voltage with respect to an inversion reference voltage on the basis of the selected gray scale voltage, an AC switching signal and the inversion reference voltage, and for outputting different liquid crystal supply voltages for one and the same display data to a liquid crystal panel.
