LED DRIVING APPARATUS, METHOD FOR DRIVING THE LED AND DISPLAY APPARATUS USING THE SAME

摘要

PURPOSE: An LED driving device, an LED driving method, and a display device using the same are provided to easily apply driving voltage to a module by exciting an inductor. CONSTITUTION: An LED module(310) provides backlight to a display panel. An LED driving part(321) applies driving voltage to the LED module. The LED driving part selectively uses current flowing in an inductor. A sensing part(323) senses the amount of the current flowing in the inductor. A switching control part(322) controls the amount of the driving voltage according to a sensed result of the sensing part.
