摘要： A light source device includes a light source module having a light-emitting block, an image analysis part, a duty ratio calculation part, a duty ratio determination part and a signal generation part. The image analysis part extracts representative luminance data of the light-emitting block based on pixel data. The duty ratio calculation part calculates duty ratio data of the light-emitting block based on the representative luminance data. The duty ratio determination part generates determined duty ratio data of the light-emitting block based on the duty ratio data from a first period, and the signal generation part generates a driving signal having a duty ratio corresponding to the determined duty ratio data to drive the light-emitting block.

摘要： A driving method of a liquid crystal display is provided for improving an echo phenomenon in the screen and improving crosstalk in a 3D display device. The liquid crystal display includes a liquid crystal panel and a light source unit divided into a plurality of blocks and that irradiates light by a light source unit of the corresponding block being driven at a response time of liquid crystals of the liquid crystal panel. Data of a liquid crystal panel corresponding to the plurality of blocks is analyzed to determine an n-th block corresponding to a portion having the highest visibility. Driving periods of light source units of the n-th block, an (n−1)-th block, and an (n+1)-th block are synchronized.
