DRICING DEVICE OF BACKLIGHT UNIT, DRIVING METHOD THEREOF AND LIQUID CRYSTAL DISPLAY DEVICE HAVING THE SAME

摘要

A driving device of a backlight unit, a driving method thereof, an LCD(Liquid Crystal Display) including the same are provided to prevent life-time reduction of a light emission diode caused by a high temperature and brightness deterioration caused by a low temperature, by selectively driving the light emission diode according to an internal temperature of a backlight unit. A plurality of fluorescent lamps(153) are disposed at predetermined intervals. A plurality of light emission diode packages(155) are disposed between the fluorescent lamps. A temperature sensor(140) detects a peripheral temperature. A driving unit(160) selectively drives the fluorescent lamps and the light emission diode packages according to a peripheral temperature detected by the temperature sensor.
