Abstract
An information display system includes a pixelated display including a plurality of pixels, each pixel including a plurality of subpixels, an inter-pixel region defined between two of the subpixels and at least one subpixel zone. Also included is an optically-scattering layer in optical communication with the pixelated display, the optically-scattering layer including: a matrix and phase-separated microdomains, wherein the matrix and the phase separated microdomains have different refractive indices and wherein the phase-separated microdomains are disposed in at least one subpixel zone.
