  • Patent number: 11308884
    Abstract: A display device includes: a display unit; a display driver configured to drive the display unit; and a display-data generator configured to transfer a screenful of update display data to the display driver. The display driver includes a light-emission controller configured to control self-luminous elements to emit light, and a memory storing a screenful of the update display data. After a lapse of a predetermined time period from a driving stop time, the display driver reads the update display data stored in the memory and then uses the update display data to drive a screen, the driving stop time being a time when the display unit is stopped from driving based on the update display data. The display driver causes the self-luminous elements of the display unit to emit light, even during a display update or no display update performed on the display driver by the display-data generator.
