A display apparatus includes an array of microlenses disposed in or on a substrate. In one embodiment, the apparatus includes scattering centers disposed in or on the substrate and offset relative to the microlenses. The scattering centers are positioned substantially at focal points of the microlenses such that light incident upon a first side the substrate is scattered off of the scattering centers and collimated by corresponding ones of the microlenses before emission from the display apparatus. In another embodiment, the apparatus includes light emitting pixels disposed in or on the substrate and offset relative to the microlenses. The light emitting pixels are positioned substantially at focal points of the microlenses such that non-collimated light emitted from the light emitting pixels is collimated by the microlenses upon emission from the display apparatus.
