Abstract
A driving circuit of LCD includes a common signal generator and a modulation circuit. The modulation circuit can generate a first frequency, a second frequency, and a third frequency. The common signal generator generates a swing common signal according to the first frequency, and modulates the frequency of the common signal in the frequency range between the second frequency and the third frequency.
