Abstract:
In a backlight unit and an LCD apparatus having the backlight unit, in which the backlight unit includes a plurality of lamps and an inverter, the inverter provides the lamps with current. The inverter reduces current provided to the lamps to turn off the lamps. Therefore, currents are gradually decreased to reduce noise generated by the transformer when the lamps are turned off.
