摘要: A display device includes: a display element for displaying an image on a screen; and driving means for driving the display element so that a scan mode for carrying out scanning and a pause mode for pausing the scanning are alternately repeated. The driving means drives, by transmitting a pause and drive control signal to the display element, the display element so that scanning of a single frame is carried out by going through the scan mode twice and the pause mode twice. During the pause mode, the driving means outputs, to a touch panel, a detection command signal which commands that detection be carried out.
