Abstract: Embodiments relate to a display device and driving method thereof. A display device includes a display panel including a sub-pixel, a data driver including a driving circuitry configured to output data voltage to the sub-pixel and a sensing circuitry configured to sense a characteristic of the sub-pixel, and a timing controller configured to determine a compensation value of video data based on the sensed characteristic and corrects the compensation value based on sensing of an output data voltage of the driving circuitry.
