Abstract
An image display device includes a substrate; a sparse array of light emitting elements formed on one side of the transparent substrate, the light emitting element being selectively addressable to form an image; an array of lens-lets located on the opposite side of the substrate, the focal plane of the lens-lets being at the one side of the substrate and the lens-lets being arranged with respect to the light emitting elements such that the light emitted by the light emitting elements is directed by the respective lens-lets to intersect at a common region associated with a predetermined viewing distance; and the sparseness of the array of the light emitting elements being such that the ratio of the light emitting area of the light-emitting element under a lens-let to the total area of the lens-let is less than or equal to 0.25.
