A luminance compensation method for a display device includes measuring a luminance of each of white grayscale values, measuring an actual luminance value for each of colors, determining a target luminance value for each of the colors based on the luminance of each of the white grayscale values and a luminance contribution ratio of each of the colors, determining a luminance compensation amount for each of the colors based on the target luminance value and the actual luminance value, and compensating for input image data for each of the colors based on the luminance compensation amount.

Luminance compensation method for display device

A display device includes a display panel which includes a pixel including a driving transistor and a light-emitting element, and a sensing line connected to the pixel. A sensing driver senses a first sensing signal corresponding to mobility of the driving transistor through the sensing line, and processes the first sensing signal to output first sensing data. A driving controller receives the first sensing data from the sensing driver, generates mobility compensation data and kickback compensation data based on the first sensing data, and converts image data into compensation image data by the mobility compensation data and the kickback compensation data. A data driver converts the compensation image data into a data signal and provides the data signal to the pixel.
