Abstract
Disclosed is a display device including: a display panel configured to display an image of a series of frames based on input image data; a light source configured to emit light to the display panel; a light source driver configured to supply a driving signal to the light source so that the light source can emit light; and a processor configured to detect a brightness change of a first frame of image data input to the display panel, make the light source driver supply a driving signal having a first frequency to the light source when the brightness change is lower than a predetermined boundary value, and make the light source driver supply a driving signal having a second frequency lower than the first frequency to the light source when the brightness change is higher than the boundary value. Thus, it is possible to decrease a flicker that occurs when the liquid crystal display device is driven with a PWM signal, i.e. an impulse signal for reducing a motion blur.
