A display device is disclosed that includes a display panel, a controller, and a data driver. The controller is configured to determine first luminances with respect to a reference grayscale in a second frame when the reference grayscale is displayed in the second frame after the reference grayscale is displayed in a first frame. The controller is configured to determine second luminances with respect to the reference grayscale in the second frame when the reference grayscale is displayed in the second frame after a minimum grayscale is displayed in the first frame. The controller is further configured to temporally and spatially arrange first data corresponding to the reference grayscale and second data corresponding to the minimum grayscale to generate a data signal. And, the controller is configured to drive the display panel with a digital driving method in a first grayscale section, and drive the display panel with an analog driving method in a second grayscale section. The data driver is configured to generate a data voltage based on the data signal.
