Abstract
A digital-to-analog converter unit is adapted to apply at an output a pixel charging voltage for a liquid crystal display corresponding to a digital signal. A digital-to-analog converter generates a high resolution signal. An offset generator generates an offset voltage according to an inversion signal and an adder adds the offset voltage to the high resolution signal thus providing the pixel charging voltage.
