Abstract: Provided is a light-emitting diode (LED) driving system. The LED driving system includes an LED current controller, a detector, and a system controller. The LED current controller is configured to control a current flowing through a plurality of LED arrays including at least one LED, such that no current flows through a first LED array from among the plurality of the LED arrays and a current flows through a second LED array from among the plurality of the LED arrays. The detector is configured to detect a sensing voltage from the first LED array. The system controller is configured to determine, based on a comparison result between the sensing voltage and a reference voltage, a failure of the at least one LED included in the second LED array.
