Claim 0:
1. A method of driving a light emitting diode (LED) backlight unit, the LED backlight unit including a plurality of LED elements that are connected to a plurality of gate lines and a plurality of source lines, the method comprising:
generating a plurality of gate signals applied to the plurality of gate lines;
generating, while the plurality of gate signals are generated, a non-overlap interval between activation intervals of two adjacent gate signals, all of the plurality of gate signals being deactivated during the non-overlap interval;
generating a plurality of source signals applied to the plurality of source lines; and
generating, while the plurality of source signals are generated, a high-impedance interval exclusively in the non-overlap interval, at least some of the plurality of source signals having a high-impedance state during the high-impedance interval.
