Electronic device and driving method of electronic device

An electronic device comprising:

• a display layer including a light emitting device including an organic light emitting material;
• a driving controller which generates image data based on a received image signal and controls the display layer;
• and
• a temperature sensor which measures a temperature of the light emitting device 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 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,
• wherein a plurality of gray levels are classified into a low gray level zone defined by some of the plurality of gray levels and a high gray level zone defined by the others of the plurality of gray levels,
• wherein the first lookup table calculating unit calculates the first lookup table for each of the plurality of gray levels by calculating the first lookup table for each group of gray levels in the low gray level zone and calculates the first lookup table for each gray level of the high gray level zone based on a maximum gray level value of the high gray level zone, and
• wherein the driving controller generates the image data based on the image signal and the second lookup table.

A driving method of an electronic device, the driving method comprising:

• generating temperature data;
• calculating a first lookup table for each of gray levels based on the temperature data and a reference lookup table set for each of a plurality of gray levels;
• calculating a luminance weight based on luminance data;
• calculating a second lookup table based on the first lookup table and the luminance weight, wherein the second lookup table is different from the first lookup table;
• and
• generating image data based on an image signal and the second lookup table.
