摘要

light source including a plurality of image areas of the light source blocks is provided with a light source for providing light to the module a local light source driving method comprises a first target brightness value and the first light source and the neighbor with the second target brightness value of the second image area is adjacent to the second light source the first and second light sources of the first light source and adjacent to the first image section first determining the duty ratio corresponding to the . Compensating for the determined duty ratio to the first value with a target luminance of the other image areas other than the first and second image areas of a plurality of image area that receives the light from the first and second light sources . The first predetermined duty ratio that drives the first and second light sources in the compensated drive signal . ; local dimming driving , the target luminance value , the compensation duty ratio
