ABSTRACT:
Provided is a light device. The light device comprises a backlight unit, a multi-sensor unit, a backlight driving unit, and a backlight control unit. The backlight unit comprises light emitting diode devices to provide light. The multi-sensor unit is included in a light emission region of the backlight unit and senses a wavelength and/or intensity of light emitted from the light emitting diode devices and transmits sensed values as feedback. The backlight driving unit supplies driving power to the light emitting diode devices, and the backlight control unit receives the sensed values from the multi-sensor unit to control the light emitting diode devices through the backlight driving unit.
