Abstract
A driving circuit of an LCD device contains a driving circuit. The driving circuit includes a digital-to-analog converter that outputs a first data signal by converting a digital data signal to an analog data signal; a modulator that outputs a second data signal by modulating the amplitude and pulse width of the first data signal; and a combiner that combines the first data signal with the second data signal. The combiner provides the combined data signal to a data line of an LCD panel.
