    • A display device includes a display panel for displaying an image. The display device further includes a lens configured to refract at least a portion of a collimated light having a center ray, a first outermost ray, a second outermost ray, a first plurality of rays between the first outermost ray and the center ray, and a second plurality of rays between the second outermost ray and the center ray. The lens may concentrate the first plurality of rays such that a first position on the display panel has a first light intensity. The lens may concentrate the second plurality of rays such that a second position on the display panel has a second light intensity. Each of the first light intensity and the second light intensity is substantially greater than a center light intensity on the display panel corresponding to at least the center ray.
