    摘要: A backlight unit for a liquid crystal display (LCD) device, disposed under a liquid crystal panel to illuminate the liquid crystal panel. The backlight unit includes a light guide plate, first and second light emitting diode (LED) arrays, disposed on adjacent sides, perpendicular to each other, of the light guide plate, each array having a plurality of LED blocks, consisting of one or more LEDs, and a control unit that controls electric signals, respectively inputted to the LED blocks, to regulate luminance for the respective LED blocks, wherein light emitted from the first and second LED arrays is overlapped each other in the light guide plate.
