Abstract: The present invention relates to an image display apparatus. The image display apparatus according to an embodiment of the present invention a display including an organic light-emitting diode (OLED) panel, and a controller to control the OLED panel, in which, in a case where an image to be displayed on the OLED panel is a moving image, during a first duration, the display displays a portion of a first frame image on a first area of the OLED panel and displays a portion of a second frame image before the first frame image on a second area other than the first area of the OLED panel, and in which, in the case where the image to be displayed on the organic light-emitting is the moving image, during a second duration after the first duration, the display displays a black image on all display areas of the OLED panel.

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.

Abstract: The present invention relates to a display device and a control method therefor, and involves the concept of controlling a display to reduce luminance from a default luminance to a first luminance for a first reduction time when brightness of a fixed area is maintained for a first predetermined time or more, and controlling the display to increase the luminance from the first luminance to the default luminance, when a set-top box receives, from an external device within a second predetermined time, a first signal for changing a screen from a first screen to a second screen.
