Abstract: The present specification discloses a display device which, upon consecutive viewing of images of different frequencies, may improve abnormalities on a screen according to frequency change, and a method for controlling same. A digital device, according to one embodiment of the present invention, comprises: a processor; a display unit comprising a plurality of pixels; and a timing controller for temporally controlling a driving frequency such that the display device is driven, wherein the timing controller controls a light-emitting signal at a preset duty ratio in one frame interval, and when the display unit displays an image of a first input frequency and thereafter displays an image of a second input frequency, a value of a vertical blanking interval for each frame interval gradually changes.
