Abstract: An electronic device is disclosed. The electronic device includes a backlight unit including a plurality of backlights; a driving unit for driving the backlight unit; and a processor for identifying, based on luminance information about each of the plurality of backlights, a number of time intervals in which each of the plurality of backlights is to be turned on from among a plurality of time intervals included in a backlight dimming interval, and controlling the driving unit so that the plurality of backlights are turned on during the identified number of time intervals by variously changing times at which the plurality of backlights are turned on.
