Abstract: In a backlight apparatus, a master driving circuit generates a transmission frame including a training period including a clock training pattern and a data period including a plurality of data packets respectively corresponding to the plurality of blocks. A plurality of slave driving circuits correspond to the plurality of blocks, respectively, and are connected to the master driving circuit in a daisy chain structure. Each slave driving circuit receives the transmission frame through the daisy chain structure, recovers a clock based on the clock training pattern, and drives the plurality of light emitting elements included in a corresponding block among the plurality of blocks based on its own data packet among a plurality of data packets.
