1. A display device comprising:
a display panel including a display area including a plurality of pixels;
a touch sensing unit disposed on a front surface of the display panel;
a display driving circuit, configured to drive the pixels of the display area based on display control firmware; and
a touch driving circuit configured to drive touch electrodes of the touch sensing unit based on touch driving firmware, and further configured to generate touch coordinate data,
wherein the display control firmware and the touch driving firmware are initialized or changed according to a comparison result between a flicker noise detection value of the display area and a reference flicker noise detection value, wherein the flicker noise detection value is determined by measuring a change in luminance, of the plurality of pixels, over time with a flicker detection pattern displayed in the display area.
