Display Device

Abstract

A display device includes a display panel having a plurality of sub-pixels to display an image; a data driver for supplying image data to the plurality of sub-pixels; a gate driver for supplying a gate signal to the plurality of sub-pixels; a controller configured to convert a driving frequency of each of the data driver and the gate driver in a high frame rate mode; and a gamma voltage generator for generating gamma voltages respectively based on each driving frequency, wherein the controller is configured to generate a horizontal synchronization signal based on the driving frequency in the high frame rate mode. Accordingly, even when the driving frequency conversion occurs, image quality levels corresponding to various driving frequencies respectively may be kept uniform by applying the same operation duration to the various driving frequencies.
