Abstract: A display device may include first pixels disposed in a display area and including respective first driving transistors. A second pixel is disposed in a non-display area and includes a second driving transistor. A sensor is configured to sense a current of the second pixel during a sensing period and generate sensing data. A degradation compensator is configured to convert first image data into second image data. A data driver is configured to generate data signals based on the second image data and supply the data signals to the first pixels. The degradation compensator calculates an age of the first pixels based on accumulating the second image data, converts the first image data into the second image data by deriving a compensation value from representative compensation data according to the age of the first pixels, and calibrates the representative compensation data based on the sensing data.
