Abstract:
A backlight unit and a display apparatus are provided. The display apparatus includes a driving unit which applies a driving current using a duty cycle controlling to the light emitting unit; and a controller which controls a first driving current to be applied to the light emitting unit in a section of a plurality of frame sections, and a second driving current to be applied to the light emitting unit in another section of the plurality of frame sections. Therefore, luminance representation of backlight in a low grayscale region can be improved.
