Abstract:
Disclosed is a method for analyzing a light profile of a light source includes driving a light source of one of a plurality of blocks which divide a backlight unit, setting a light analyzing region matched to one light emission region of the light source, dividing the light analyzing region into at least two symmetric regions considering a form of the light emission region and symmetry of the light emission region, and analyzing and storing a light profile of one of the at least two symmetric regions.
