Abstract
An electronic apparatus is provided, which includes a memory storing an input image, a backlight unit, a driver configured to output a driving current to the backlight unit, and a processor configured to identify a time interval at which current is applied among a plurality of time intervals based on a value of a plurality of first bits among a plurality of bits representing a gray level value of the input image, and control the driver to change a magnitude of a current of a time interval among the plurality of time intervals based on at least one second bit which is the rest of the plurality of bits excluding the plurality of first bits, and a number of the plurality of time intervals is determined based on the number of the plurality of first bits.
