Abstract
A display device includes a display unit, a driving voltage supply unit which supplies a driving voltage to the display unit, a ripple detection circuit which detects the number of times a ripple of the driving voltage is generated, and a controller which controls the driving voltage supply unit so as to change the driving voltage based on the number of times the ripple is generated.
