    Abstract: A display device includes a display unit, a timing controller, a data driver, and a sensing unit. The display unit includes a data line, a sensing line, and a pixel that includes a light emitting element and a transistor for providing a driving current to the light emitting element. The timing controller generates a first voltage value by compensating a first grayscale value and generates a second voltage value by remapping the first voltage value from a first voltage range to in a second voltage range. The data driver generates a data voltage based on the second voltage value and supplies the data voltage to the data line. The sensing unit provides an initialization voltage to the sensing line. A voltage difference between the data voltage and a threshold voltage of the transistor is greater than or equal to the initialization voltage.
