Abstract: A backlight system includes a plurality of pixel ICs respectively including a plurality of channels connected to a plurality of LEDs and that control the LEDs to be turned on and off through the channels, and a driver IC connected to the pixel ICs and that supplies a data signal to each of the pixel ICs. The pixel ICs include a first pixel IC connected to first LEDs and a second pixel IC connected to second LEDs. The first pixel IC turns the first LEDs on or off in a first order based on first control data included in the data signal, and the second pixel IC turns the second LEDs on or off in a second order different from the first order based on second control data included in the data signal.
