Abstract
A method of driving a light source including a light-emitting block includes generating a luminance representative value based on an average grayscale value and a maximum grayscale value extracted from an image signal corresponding to the light-emitting block. The method further includes detecting a predetermined pattern of the light-emitting block, generating a compensation control signal based on the predetermined pattern, generating a compensated luminance representative value by compensating the luminance representative value based on the compensation control signal, and driving the light-emitting block based on the luminance level of the light-emitting block corresponding to the compensated luminance representative value.
