Abstract
A LCD driving circuit drives a LCD panel having a data electrode and a common electrode by applying a periodically inverted signal to the common electrode. The LCD driving circuit includes a parallel resonant circuit which has a static capacitance of the LCD panel and is coupled to the common electrode and ground. The parallel resonant circuit has a parallel resonance frequency equal to a frequency of the signal applied to the common electrode.
