Zusammenfassung:A driver and a display apparatus comprising the same are provided to correct a distorted image signal by using a common voltage from a common voltage generator. A driver of a display apparatus includes a control voltage signal generator(720), a clock signal generator(740), and a DC/DC converter(750). The control voltage signal generator converts the voltage level of a control voltage signal(VCONT) in response to an external signal(EXT). The clock signal generator generates a clock signal(CLK), of which duty ratio is varied according to the voltage level of the control voltage signal. The DC/DC converter converts the voltage level of an input voltage in response to the clock signal and outputs the result as a driving voltage(AVDD).
