1. An electronic device comprising:
a display layer which displays an image, wherein the display layer includes a plurality of pixels connected with a plurality of data lines and a plurality of scan lines;
a data driving circuit which drives the plurality of data lines;
a scan driving circuit which drives the plurality of scan lines;
a driving controller which generates image data based on a received image signal and controls the data driving circuit and the scan driving circuit; and
a temperature sensor which measures a temperature of the display layer to generate temperature data,
wherein 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
wherein the driving controller generates the image data based on the image signal and the second lookup table.
