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.

Abstract: A display device includes a data line, a pixel electrically connected to the data line, a data driver for outputting a data voltage, and a transmitter electrically connected between an output terminal of the data driver and the data line. The transmitter may transmit an instance of the data voltage to the data line in a first period. The transmitter may amplify a second instance of the data voltage to generate a reference voltage and then transmit the reference voltage to the data line in a second period different from the first period. The pixel includes a light emitting element for emitting light in response to the first instance of the data voltage. A voltage level of the reference voltage may be higher than a voltage level of the data voltage.
