Abstract: A display apparatus includes a temperature sensor, a timing controller, a data driver and a display panel. The temperature sensor senses a temperature, the timing controller includes a dynamic capacitance capture (“DCC”) block, which converts a green data, a red data and a blue data into a green compensation data, a red compensation data and a blue compensation data, respectively, based on the temperature sensed by the temperature sensor, and the data driver converts the red compensation data, the green compensation data and the blue compensation data into a data voltage and outputs the data voltage. The display panel receives the data voltage and displays an image.

Abstract: 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.
