Abstract
A direct view display device includes a light unit, a collimating unit, an image display unit, and a contrast enhancement unit. The contrast enhancement unit includes opposing first and second major surfaces. The first major surface includes an array of optical elements. The second major surface includes a light absorbing layer and an array of apertures in the light absorbing layer and corresponding to the array of optical elements. The optical elements are disposed between the light unit and the light absorbing layer. The collimating unit is disposed between the light unit and the contrast enhancement unit. The image display unit is disposed between the collimating unit and the contrast enhancement unit. The contrast enhancement unit and the image display unit are arranged such that each optical element of the contrast enhancement unit is aligned with at least one corresponding pixel of the image display unit.
