Abstract: Disclosed is a display apparatus in which each pixel corresponds to at least one light-emitting element. The display apparatus includes a display including a plurality of pixels, a driver configured to drive a plurality of light-emitting elements constituting the plurality of pixels, and a processor configured to control the driver to drive the plurality of light-emitting elements based on a first pulse width modulation signal having a duty corresponding to a grayscale of an input image, and to control the driver to drive light-emitting elements constituting a specific pixel, among the plurality of pixels, using a second PWM signal having a duty corresponding to the grayscale of the input image, wherein a frequency of the first PWM signal is different from a frequency of the second PWM signal.
