Abstract

A display device is provided. The display device includes a light emitting diode (LED) module including a plurality of LEDs; a plurality of driving integrated chips (ICs), each of the plurality of driving ICs being configured to apply voltages to a corresponding group of the plurality of LEDs; and a controller. The controller is configured to identify a first voltage corresponding to a first LED from among the plurality of LEDs based on image data, identify a first LED driving voltage as the first voltage or a second voltage based on the first voltage and a reference value, and control a first driving IC, from among the plurality of driving ICs, that corresponds to the first LED based on the first LED driving voltage.
