  • Apparatus for driving light emitting diode array and liquid crystal display device using the same
    Patent number: 8970472
    Abstract: Disclosed are an apparatus for driving a light emitting diode (LED) array and an LCD device using the same. The apparatus for driving the LED array includes a current amount setter configured to have a resistance value which varies according to a selection signal inputted from an external system, and a controller configured to generate a driving voltage and a driving current by using an input voltage inputted from the external system and the resistance value set by the current amount setter, and supply the driving voltage and the driving current to the LED array.
    Type: Grant
