Abstract:
In a method of local dimming a light source, which includes driving a light source including a plurality of light-emitting blocks by individually driving the light-emitting blocks, the dimming level of each light-emitting block is determined. In the method, the luminance of a first light-emitting area may be adjusted according to a size of the first light-emitting area corresponding to a display area in which an image having a maximum luminance is displayed.
