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.

Abstract: A display apparatus includes a power supply device. The power supply device includes a power supply part and an integrated circuit chip. The power supply part outputs a first power to drive a backlight and a second power to drive a main circuit. The integrated circuit chip increases, based on a control signal to adjust a brightness of the backlight being received, a current value of the second power, and reduces, based on the control signal not being received for a first threshold time, the current value of the second power.
