Abstract
A phosphor-based multi-colored display is provided which includes a spatial light modulator comprising an addressable array of apertures each corresponding to a respective sub-pixel in the display; an array of phosphor regions each indexed to a corresponding aperture of the spatial light modulator; and a backlight which provides quasi-monochromatic light to phosphor within each of the phosphor regions. The phosphor within each of the phosphor regions, upon being excited by the quasi-monochromatic light of the backlight, emits light having a color different from a color of the quasi-monochromatic light, through the corresponding aperture of the spatial light modulator.
