Abstract: An electronic device includes a display layer, a data driving circuit, a scan driving circuit, a driving controller, and a temperature sensor which measures a temperature of the display layer to generate temperature data. The driving controller includes a first lookup table calculating unit which calculates a first lookup table based on the image signal, the temperature data, and a reference lookup table set for each of a plurality of gray levels, a luminance compensating unit which calculates a luminance weight based on luminance data, and a second lookup table calculating unit which calculates a second lookup table based on the first lookup table and the luminance weight, and the driving controller generates the image data based on the image signal and the second lookup table.
