Abstract: In a backlight assembly, a display apparatus having the backlight assembly, a method for driving the backlight assembly and a method for driving the display apparatus, the backlight assembly includes a plurality of light sources and a light source driving unit. The light sources are disposed along a direction and emit light. The light source driving unit causes the light sources to sequentially emit light along the direction, and causes each of the light sources to emit light during a first emitting period of a time period, and then causes each of the light sources to emit light during a second emitting period of the time period. The time period is substantially the same as a single frame. Accordingly, each of the light sources emits light again after the light sources have emitted light once, so that motion blur in the display apparatus may be decreased.
