1. An electronic device comprising:
a display panel including a pixel;
a sensor that obtains luminance data of an image displayed on the display panel;
and a signal controller that receives image data and generates corrected image data based on a compensation value in the image data, wherein
the signal controller calculates the compensation value based on initial luminance data and the luminance data, and wherein the signal controller includes:
an accumulator that stores a cumulative amount of stress applied to the pixel;
a weight calculator that calculates a weight based on the luminance data and the initial luminance data;
a lookup table that stores a plurality of intermediate compensation values according to the cumulative amount of the stress; and
a compensator that calculates the compensation value based on the plurality of intermediate compensation values and the weight, corrects the image data based on the compensation value, and outputs the corrected image data.
