Abstract
A display device includes: a driving voltage provider for generating a PWM signal according to the frequency of a clock signal, and providing a driving voltage generated according to the duty ratio of the PWM signal to at least one of the pixels, the data driver, and the scan driver. The driving voltage provider tunes the frequency of the clock signal to a first frequency in a first section, tunes the frequency of the clock signal to a second frequency smaller than the first frequency in a second section in which the magnitude of a driving voltage is larger than that in the first section, and tunes the frequency of the clock signal to a third frequency larger than the first frequency in a third section in which the magnitude of a driving voltage is smaller than that in the first section.
