Abstract
A backlight unit for a dynamic image and a display employing the same are provided. The backlight unit is used for a light source of a display and includes light-emitting devices located separately on a substrate, an image analyzer which analyzes an image signal and extracts position information on a region requiring the relative increase or decrease of brightness, and a control unit which independently drives and controls the light-emitting devices located in a region corresponding to the position information inputted from the image board. Accordingly, the display employing the backlight unit can provide a more dynamic and realistic image.
