Abstract: A display device includes a display panel, a luminance compensator, and a data driver. The display panel includes a plurality of pixels. The luminance compensator is configured to calculate a scaling factor based on a target current, a black image current, and a sensing current. The target current is calculated based on an input current input to the display panel. The sensing current is measured from the display panel. The data driver is configured to generate a data voltage based on input image data to supply the data voltage to the pixels. The data voltage has a voltage level adjusted based on the scaling factor.
