    Abstract: A display device includes a backlight unit including a plurality of light emitting blocks, a first controller configured to generate first block representative value information for first pixel blocks based on first image data, and a second controller configured to generate second block representative value information for second pixel blocks based on second image data. The first controller receives the second block representative value information from the second controller, and the second controller receives the first block representative value information from the first controller. The first and second controllers generate duty information for the plurality of light emitting blocks based on the first and second block representative value information, and generate light profile information of the backlight unit. The first controller compensates the first image data based on the light profile information, and the second controller compensates the second image data based on the light profile information.
