Abstract: An electronic apparatus is provided. The electronic apparatus includes: a plurality of LED arrays disposed in parallel, a first sensing inductor connected to a first LED array of the plurality of LED arrays in series, a first auxiliary inductor disposed adjacent to the first sensing inductor, a second sensing inductor connected to a second LED array of the plurality of LED arrays in series, a second auxiliary inductor disposed adjacent to the second sensing inductor, a variable resistance connected to the plurality of LED arrays and configured to adjust an amount of a current flowing to the plurality of LED arrays according to a resistance value, and an LED driver configured to, based on at least one of a first induced voltage generated on the first auxiliary inductor or a second induced voltage generated in the second auxiliary inductor being a threshold voltage or more, identify that an error occurs in at least one of the first LED array or the second LED array, and adjust the resistance value of the variable resistance based on the identified result.
