Abstract
A display device includes: a display panel; a driving frequency converter circuit configured to convert a driving frequency according to an input image data. A common voltage controller outputs a common voltage data corresponding to the driving frequency; and a common voltage generator receives the common voltage data to generate a common voltage and outputs the common voltage to the display panel. The common voltage has an inclined waveform within an integer multiple of a frame period.
