Abstract
A method of driving a light source includes: determining a location of pixel data of a display relative to a plurality of light-emitting blocks of a light source, obtaining a plurality of luminance values of the light-emitting blocks corresponding to the location by using a lookup table (LUT) storing the luminance values of the light-emitting blocks, generating a plurality of histograms corresponding to the light-emitting blocks, determining a plurality of target luminance values of the light-emitting blocks using the histograms, and driving the light-emitting blocks using the determined target luminance values. The luminance values of the light-emitting blocks are based on the location of the pixel data within an image block of the display corresponding to each light-emitting block. Each of the histograms indicates a frequency of each of the luminance values of a respective one of the light-emitting blocks.
