Abstract
A method of driving a light emitting diode (LED) backlight unit, which includes a plurality of LED elements that are connected to a plurality of gate lines and a plurality of source lines, includes generating a plurality of gate signals applied to the plurality of gate lines. While the plurality of gate signals are generated, a non-overlap interval between activation intervals of two adjacent gate signals is generated. All of the plurality of gate signals are deactivated during the non-overlap interval. A plurality of source signals applied to the plurality of source lines are generated. While the plurality of source signals are generated, a high-impedance (Hi-Z) interval included in the non-overlap interval is generated. At least some of the plurality of source signals have a high-impedance state during the high-impedance interval.
