A display device includes L number of display panels where L is a positive integer greater than 1; a driving circuit having L number of controllers for driving the respective display panels; and a central control unit configured to control the driving circuit. The controllers are configured to be synchronized with one another based on a clock signal from the central control unit, and each of the controllers is configured to sequentially and continuously select each one of K number of lines (where K is a positive integer greater than 1) arranged in a row in the corresponding display panel, and allow the selected line to emit light. Further, a direction for sequentially and continuously selecting each one of the lines is set to be the same in all the display panels.
