Abstract
A display apparatus includes: a backlight to generate light; a display panel to display an image by utilizing the light; a driving part to provide image signals corresponding to the image to the display panel; and a timing controller to drive the backlight, to drive the driving part at a first frequency when the image is a moving image, and to drive the driving part at a second frequency lower than the first frequency when the image is a still image. The timing controller is to set the second frequency based on a value obtained by applying a reduction rate of a flicker index corresponding to a dimming index of the backlight to a flicker index of image signals of a previous frame.
