Abstract
A display device includes a display panel having a plurality of gate lines and a plurality of data lines crossing each other and pixels formed at intersections thereof; a gate driving circuit that generates a gate pulse based on a gate power voltage and applies the gate pulse to the gate lines; a data driving circuit that divides the data power voltage to convert input digital video data into an analog data voltage and applies the data voltage to the data lines; a power voltage control circuit that detects an input frame frequency and generates a different power control signal in accordance with the detected frame frequency; and a power voltage adjusting circuit that adjusts at least one of the gate power voltage and the data power voltage differently from a predetermined reference level in response to the power control signal.
