Claim:
1. A display system, the display system comprising: a pixelated display comprising a plurality of pixels, each of the plurality of pixels having a pixel size and comprising a plurality of subpixels, wherein the pixelated display generates an inter-pixel gap between a first subpixel and a second subpixel when the first subpixel and the second subpixel are on and one or more subpixels located between the first subpixel and the second subpixel are off; a transparent substrate disposed in front of and substantially parallel to the pixelated display, the transparent substrate having an antiglare surface distal from the pixelated display; and a diffraction element having a grating period disposed between the antiglare surface and the pixelated display, wherein the transparent substrate is separated from the pixelated display by a predetermined distance and the grating period is determined at least based on the predetermined distance and the size of the inter-pixel gap.
