1. A display device comprising:
a sensor configured to sense characteristic values of a circuit element included in a pixel of the display device using an input initialization voltage and an input data voltage supplied to the pixel in a sensing period of one frame period;
a timing controller configured to calculate a compensation data voltage using the characteristic values, and calculate an adjusted initialization voltage and an adjusted data voltage using the compensation data voltage; and
a data driver configured to output the adjusted initialization voltage and the adjusted data voltage to the pixels during the sensing period in response to a control signal output from the timing controller,
wherein the characteristic values include a threshold voltage of a driving transistor, a mobility of the driving transistor, and a characteristic value of a light emitting diode.
