Display device and method of setting driving firmware of the same

An electronic 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 over time of a flicker detection pattern displayed in the display area, and
• wherein the flicker noise detection value is computed from a luminance difference value measured through a photometer, wherein the luminance difference value is measured over time while gradually changing a display driving frequency and voltage values of output signals of the display control firmware and gradually changing a touch driving frequency and voltage values of a touch driving signal of the touch driving firmware through a flicker noise detection device.

A method of setting driving firmware of a display device, the method comprising:

• driving pixels included in a display panel with a display driving circuit, wherein the pixels are driven based on display control firmware;
• driving touch electrodes of a touch sensing unit with a touch driving circuit, wherein the touch electrodes are driven based on touch driving firmware and generating touch coordinate data;
• detecting flicker noise of an image displayed on the display panel using a flicker noise detection device that measures luminance of the driven pixels;
• and
• changing the display control firmware and the touch driving firmware according to a comparison result between a flicker noise detection value detected by the flicker noise detection device and a pre-quantified flicker noise detection value.
