Abstract

A backlight unit including a backlight module and a backlight control module. The backlight module includes a printed circuit board including blocks arranged in an M×N matrix, in which M and N are natural numbers of 2 or greater, and M blocks are arranged in a horizontal direction and N blocks are arranged in a vertical direction, and at least one light emitting device disposed on each of the blocks. The backlight control module is configured to perform a dimming control of the M×N blocks such that the at least one light emitting device in one block can be controlled independently from other light emitting devices disposed in the remaining blocks that are disposed in the horizontal direction and in the vertical direction with respect to the one block.
