Abstract: A display device includes a display panel and a backlight device. A display system includes: a display driver; a light source driver that drives the backlight device, based on luminance information that sets a luminance of a plurality of light source elements; and a display controller. The light source driver causes the plurality of light source elements to emit light, based on a light-emission frame update that is faster than an image frame update. The light source driver causes the plurality of light source elements to emit light in an i-th light-emission frame. At this point, the luminance information of the light source element corresponding to a scan area scanned by the display driver in the i-th light-emission frame, of the plurality of light source elements, is updated, based on image data in the scan area at a timing before the i-th light-emission frame.
