Abstract
An electronic device comprises: a memory to store an image input; a backlight unit; a driving unit to output a driving current to the backlight unit; and a processor to identify, based on a grayscale value of the image, a first intensity of the driving current corresponding to one from among a plurality of time sections of a backlight dimming section, obtaining, based on the identified first intensity, a first control value that allows control of an intensity of the driving current, providing a second control value, which is greater than a first control value to the driving unit, that allows the driving unit to output a driving current of a second intensity that is greater than the first intensity, and provide the first control value to the driving unit that allows the driving unit to output the driving current of the first intensity during the one time section.
