Abstract
A display device including a display unit including a plurality of data lines for transmitting data currents, a plurality of scan lines for transmitting scan signals, and a plurality of pixel areas defined by the data lines and the scan lines; a data driver for converting a plurality of grayscale data that include first data and second data into at least one of the data currents, and applying the at least one of the data currents to at least one of the data lines; and a scan driver for sequentially applying the scan signals to the plurality of scan lines, and wherein the data driver divides the plurality of grayscale data into at least two grayscale ranges including a first grayscale range, outputs a first current of the first grayscale range including at least one of the plurality of grayscale data by using the first data, and outputs a second current that corresponds to the second data in the first grayscale range.
