Abstract
In accordance with an embodiment, a display device may include a display panel including a plurality of pixels, a dimming controller for setting a first gamma correcting offset of a reference pixel among the plurality of pixels, setting a second gamma correcting offset of at least one pixel other than the reference pixel among the plurality of pixels, and generating a corrected gamma reference voltage per pixel using the first gamma correcting offset and the second gamma correcting offset and a data driver applying the corrected gamma reference voltage to each pixel of the display panel. According to an embodiment, there may be provided a display device capable of eliminating color shift by setting an offset for a gamma reference voltage per pixel and a driving method of the same.
