Abstract
A backlight unit usable in a liquid crystal display. In one embodiment, the backlight unit includes a substrate, a first plurality of light emitting elements positioned on the substrate, and a second plurality of light emitting elements positioned on the substrate, where the first plurality of light emitting elements positioned on the substrate are arranged in rows, such that two neighboring rows define a first pitch therebetween and the second plurality of light emitting elements positioned on the substrate are arranged in a row such that the row of the second plurality of light emitting elements is separated from the closest neighboring row of the first plurality of light emitting elements by a second pitch, where the first pitch is less than the second pitch.
