Abstract
A backlight system includes a backlight and a master driving circuit. The backlight includes a plurality of slave driving circuits and a plurality of light sources driven by the plurality of slave driving circuits, wherein the plurality of slave driving circuits are arranged in a matrix of driving rows and driving columns such that first through m-th slave driving circuits, where m is a positive integer greater than one, are arranged in each driving row of the driving rows, and the first through m-th slave driving circuits are connected in a daisy chain structure. The master driving circuit is configured to generate a plurality of input data signals, wherein each input data signal of the plurality of input data signals corresponds to the each driving row, and the each input data signal includes first through m-th packets including luminance data corresponding to the first through m-th slave driving circuits.
