  • Publication number: 20140028657
    Abstract: An object of the present invention is to provide (i) a display device which, during a display of a moving image and a still image, reduces electric power consumption without causing a deterioration in display quality, and (ii) a method for displaying the display device. In an intermittent drive mode in which driving and a pause of the driving are repeated, an image identification section (6) identifies an input image (image data (DA)) as a still image or a moving image. In a case where the input image is identified as the moving image, a drive/pause control section (7) generates a drive/pause control signal (DSC) in accordance with a period ratio which is in accordance with the moving image. A timing control section (8) generates a driver control signal so that intermittent driving is carried out.
