Abstract: A display device includes a display panel including a plurality of pixels, a controller configured to output image data and a gated clock signal, the image data including a plurality of pixel data for the plurality of pixels, and a data driver configured to receive the image data and the gated clock signal from the controller, and to sample the image data in response to the gated clock signal. The controller detects a repeated data pattern where same pixel data is repeated in the image data, generates a clock enable signal having an off level in a period in which the repeated data pattern is transferred, and gates an input clock signal in response to the clock enable signal to produce the gated clock signal.
