    Abstract: A display device according to an embodiment of the disclosure includes a timing controller, a scan driver including a plurality of stages connected to a plurality of clock signal lines and generating a plurality of scan signals in response to the scan start signal, a data driver configured to generate a plurality of data signals based on the image data, and a pixel portion including a plurality of pixels. One stage in the scan driver transmits a carry signal to 2n-th next stage. The timing controller selects any one of a normal frequency and low frequencies lower than the normal frequency as a driving frequency based on the input image data, and adjusts a clock duty of the plurality of clock signals so that a time required to output all of the plurality of scan signals during one frame is constant irrespective of the driving frequency.

    Abstract: A display device includes a display panel including a plurality of pixels, a data driver which provides data signals to the plurality of pixels, and a controller which controls the data driver. The controller writes frame data to a frame memory, reads the frame data in each of a plurality of frame periods, performs in a first frame period of the plurality of frame periods a still image detection operation that determines whether the frame data represent a still image, and does not performs the still image detection operation in a second frame period of the plurality of frame periods subsequent to the first frame period.
