Abstract
A display device includes a sensor, a timing controller, and a data driver. The sensor senses characteristic values of an element included in a pixel of the display device using input initialization and data voltages in a sensing period of one frame period. The timing controller calculates compensation data voltage using the characteristic values, and calculate adjusted initialization and data voltages in the sensing period by using the compensation data voltage. The data driver output the adjusted initialization and data voltages to the pixel during the sensing period in response to a control signal output from the timing controller.
