Abstract
A display device includes a frame frequency detector, a data generator, a data driver, and a plurality of pixels. The frame frequency detector is configured to detect a varied frame frequency to generate frame frequency information. The data generator is configured to receive an image signal and the frame frequency information, confirm an expanded frame period exceeding a reference frame period in one frame from the frame frequency information, and correct an image data signal corresponding to the image signal to correspond to a luminance changed according to the expanded frame period. The data driver is configured to output a data voltage corresponding to the image data signal. The plurality of pixels is configured to emit luminance corresponding to the data voltage. The reference frame period is a period in which the plurality of pixels is configured to emit light with a constant luminance corresponding to the data voltage.
