Abstract
Embodiments of the disclosure provide a backlight module using MJT LEDs and a backlight unit including the same. More specifically, embodiments of the disclosure provide a backlight module, which includes MJT LEDs configured to increase an effective light emitting area of each of light emitting cells and optical members capable of uniformly dispersing light emitted from the MJT LEDs. In addition, embodiments of the disclosure provide a backlight unit using the backlight module, thereby reducing the number of LEDs constituting the backlight unit while allowing operation at low current.
